According to the Humean theory of motivation, desire is identified as the primary source of motivation, while cognitive states like beliefs are recognized as necessary but not sufficient conditions. This paper conducts a comprehensive analysis of the established teleological argument supporting the Humean theory of motivation. The analysis finds that recent anti-Humean strategies cannot conclusively challenge the core premises of this argument. While this result may initially imply a strong and convincing defense of the Humean theory against opponents’ criticisms, it (...) will be shown that the argument can withstand objections only through the adoption of an assumption that renders it unfalsifiable.

According to the causal-historical theory of reference, natural kind terms refer in virtue of complicated causal relations the speakers have to their environment. A common objection to the theory is that purely causal relations are insufficient to fix reference in a determinate fashion. The so-called hybrid view holds that what is also needed for successful fixing are true descriptions associated in the mind of the speaker with the referent. The main claim of this paper is that the objection fails: reference (...) fixing of natural kind terms can be purely causal. The main argument draws inspiration from recent theoretical advances made in metaphysics of kinds by Marion Godman, Antonella Mallozzi, and David Papineau. The main claim is that their notion of super-explanatory properties may explain how reference of many kind terms can be fixed purely causally. (shrink)

Philosophers debate about which logical system, if any, is the One True Logic. This involves a disagreement concerning the sufficient conditions that may single out the correct logic among various candidates. This paper discusses whether there are necessary conditions for the correct logic; that is, I discuss whether there are features such that if a logic is correct, then it has those features, although having them might not be sufficient to single out the correct logic. Traditional rationalist arguments suggest that (...) the necessary conditions of thought are necessary and sufficient conditions singling out the correct logical and mathematical theories. In the contemporary debate, Chalmers advocates a view along this line. Jago, analogously, suggests that the necessary conditions for thought—or, as he calls them, our basic epistemic expectations—single out a family of logical and mathematical theories. Warren and Williamson, on the other hand, argue that there are no necessary conditions of thought. I argue that there are necessary conditions for thought, and these are necessary but not sufficient conditions to be the correct logic; indeed, these are features that all logics—correct or incorrect—share. No view we can understand is ruled out by the necessary conditions for thought, but we cannot understand quite any view. Human linguistic and conceptual abilities are genetically constrained, and these constraints are our best guide to the boundaries of logic. Arguing for this, I tackle two dogmas of modern rationalism: namely, the view that the biological constraints of human cognition have no bearing on the boundaries of the epistemic space, and the view that the boundaries of thought coincide with the boundaries of language.

The mechanistic account of computation offers one promising and influential theory of computational implementation. The aim of this paper is to shore up its conceptual foundations by responding to several recent challenges. After outlining and responding to a recent proposal from Kuokkanen (2022a), I suggest that computational description should be conceptualised as a form of idealisation (selectively attending to modified subsets of model features) rather than abstraction (selectively attending to subsets of features within a target system). I argue that this (...) conceptualisation not only offers the best way of making sense of computational implementation, but also a way of resolving each of the outstanding challenges facing the mechanistic account. The idealisation view allows the mechanistic account to make sense of the omission process found in computational descriptions without leaving the relationship between physical and computational properties mysterious.

According to what Birch (2022) calls the theory-heavy approach to investigating nonhuman-animal consciousness, we select one of the well-developed theories of consciousness currently debated within contemporary cognitive science and investigate whether animals exhibit the neural structures or cognitive abilities posited by that theory as sufficient for consciousness. Birch argues, however, that this approach is in general problematic because it faces what he dubs the dilemma of demandingness—roughly, that we cannot use theories that are based on the human case to assess (...) consciousness in nonhuman animals and vice versa. We argue here that, though this dilemma may problematize the application of many current accounts of consciousness to nonhuman animals, it does not challenge the use of standard versions of the higher-order thought theory (“HOTT”) of consciousness, according to which a creature is in a conscious mental state just in case it is aware of being in that state via a suitable higher-order thought (“HOT”). We show this in two ways. First, we argue that, unlike many extant theories of consciousness, HOTT is typically motivated by a commonsense, and more importantly, neutral condition on consciousness that applies to humans and animals alike. Second, we offer new empirical and theoretical reasons to think that many nonhuman animals possess the relevant HOTs necessary for consciousness. Considering these issues not only reveals the explanatory power of HOTT and some of its advantages over rival accounts, but also enables us to further extend and clarify the theory. (shrink)

We argue that there is a large class of questions—specifically questions about how to epistemically evaluate environments that currently available epistemic theories are not well-suited for answering, precisely because these questions are not about the epistemic state of particular agents or groups. For example, if we critique Facebook for being conducive to the spread of misinformation, then we are not thereby critiquing Facebook for being irrational, or lacking knowledge, or failing to testify truthfully. Instead, we are saying something about the (...) social media environment. In this paper, we first propose that a new branch of epistemology–Environmental Epistemology–is needed to address these questions. We argue that environments can be proper objects of epistemic evaluation, and that there are genuine epistemic norms that govern environments. We then provide a positive account of these norms and conclude by considering how recognition of these norms may require us to rethink longstanding epistemic debates. (shrink)

The epistemicist theory aims to explain ignorance due to vagueness by semantic plasticity: the shiftiness of intensions across close possible worlds resulting from shiftiness in usage. This explanation is challenged by the Omniscient Speaker Puzzle (Sennet in Philos Stud 161(2):273–285, 2012). Suppose that an omniscient speaker, Barney, who knows all the facts about usage and how these facts determine the intensions of expressions, cooks up a scheme to stabilise the intension of a normally semantically plastic term like ‘rich’. It seems (...) that ‘rich’ would display all the phenomena associated with vagueness without being semantically plastic, thus making the epistemicist explanation of ignorance due to vagueness insufficient. In this paper, I present a few choice points for epistemicism that arise as a result of the puzzle. (shrink)

This paper studies the epistemic failures to reach understanding in relation to scientific explanations. We make a distinction between genuine understanding and its negative phenomena—lack of understanding and misunderstanding. We define explanatory understanding as inclusive as possible, as the epistemic success that depends on abilities, skills, and correct explanations. This success, we add, is often supplemented by specific positive phenomenology which plays a part in forming epistemic inclinations—tendencies to receive an insight from familiar types of explanations. We define lack of (...) understanding as the epistemic failure that results from a lack of an explanation or from an incorrect one. This can occur due to insufficient abilities and skills, or to fallacious explanatory information. Finally, we characterize misunderstanding by cases where one’s epistemic inclinations do not align with an otherwise correct explanation. We suggest that it leads to potential debates about the explanatory power of different explanatory strategies. We further illustrate this idea with a short meta-philosophical study on the current debates about distinctively mathematical explanations. (shrink)

In Death and Nonexistence, Palle Yourgrau defends what he calls the principle of Prior Possibility: nothing comes to exist unless it was previously possible that it exists. While this seems like a plausible principle, it’s not strong enough; it allows the impossible to come to exist. I argue for a stronger principle: nothing exists unless its existence has always been possible. Further, I argue that we then have reason to accept a surprising result: nothing exists unless its existence is always (...) possible. Or, more generally, that nothing is the case unless it’s always possible that it’s the case. (shrink)

Straightening the current ‘value-laden turn’ (VLT) in the philosophical literature on values in science, and reviving the legacy of the value-free ideal of science (VFI), this paper argues that the influence of extra-scientific values should be minimised—not excluded—in the core phase of scientific inquiry where claims are accepted or rejected. Noting that the original arguments for the VFI (ensuring the truth of scientific knowledge, respecting the autonomy of science results users, preserving public trust in science) have not been satisfactorily addressed (...) by proponents of the VLT, it proposes four prerequisites which any model for values in the acceptance/rejection phase of scientific inquiry should respect, coming from the fundamental requirement to distinguish between facts and values: (1) the truth of scientific knowledge must be ensured; (2) the uncertainties associated with scientific claims must be stated clearly; (3) claims accepted into the scientific corpus must be distinguished from claims taken as a basis for action. An additional prerequisite of (4) simplicity and systematicity is desirable, if the model is to be applicable. Methodological documents from international institutions and regulation agencies are used to illustrate the prerequisites. A model combining Betz’s conception (stating uncertainties associated with scientific claims) and Hansson’s corpus model (ensuring the truth of the scientific corpus and distinguishing it from other claims taken as a basis for action) is proposed. Additional prerequisites are finally suggested for future research, stemming from the requirement for philosophy of science to self-reflect on its own values: (5) any model for values in science must be descriptively and normatively relevant; and (6) its consequences must be thoroughly assessed.

The propensity interpretation of fitness (PIF) holds that evolutionary fitness is an objectively probabilistic causal disposition (i.e., a propensity) toward reproductive success. I characterize this as the conceptual foundation of the PIF. Reproductive propensities are meant to explain trends in actual reproductive outcomes. In this paper, I analyze the minimal theoretical and ontological commitments that must accompany the explanatory power afforded by the PIF’s foundation. I discuss three senses in which these commitments are less burdensome than has typically been recognized: (...) the PIF’s foundation is (i) compatible with a principled pluralism regarding the mathematical relationship between measures of individual and trait reproductive success; (ii) independent of the propensity interpretation of probability; and (iii) independent of microphysical indeterminism. The most substantive ontological commitment of the PIF’s foundation is to objective modal structures wherein macrophysical probabilities and causation can be found, but I hedge against metaphysically inflationary readings of this modality.

Supersymmetry (SUSY) has long been considered an exceptionally promising theory. A central role for the promise has been played by naturalness arguments. Yet, given the absence of experimental findings it is questionable whether the promise will ever be fulfilled. Here, I provide an analysis of the promises associated with SUSY, employing a concept of pursuitworthiness. A research program like SUSY is pursuitworthy if (1) it has the plausible potential to provide high epistemic gain and (2) that gain can be achieved (...) with manageable research efforts. Naturalness arguments have been employed to support both conditions (1) and (2). First, SUSY has been motivated by way of analogy: the proposed symmetry between fermions and bosons is supposed to 'protect' the small Higgs mass from large quantum corrections just as the electron mass is protected through the chiral symmetry. Thus, SUSY held the promise of solving a major problem of the Standard Model of particle physics. Second, naturalness arguments have been employed to indicate that such gain is achievable at relatively low cost: SUSY discoveries seemed to be well in reach of upcoming high-energy experiments. While the first part of the naturalness argument may have the right form to facilitate considerations of pursuitworthiness, the second part of the argument has been problematically overstated.

Episodic memory gives us the ability to mentally travel back in time to revisit and relive past experiences. In recent years, there has been an increased interest in the function of episodic memory. According to the orthodox view, episodic memory should be considered a part of a constructive system that simulates the future for sophisticated foresight and flexible planning. In this paper, I offer a novel alternative view. I argue that episodic memory provides invaluable information about the past behavior of (...) others, allowing us to identify reliable and trustworthy partners while avoiding dealing with cheaters. Theoretical models demonstrate that cooperation in groups can be maintained if potential partners use information about an individual’s past behavior to guide their behavior toward that individual. In these reputation-based models of human cooperation, individuals with a history of cheating are ostracized, whereas those with a history of cooperative behavior flourish. Against this theoretical background, it is possible to see a function of episodic memory in facilitating information exchange about others, helping group members make effective partner choices, and avoiding the risk of interacting with cheaters. If correct, episodic memory may have played a significant role in the evolution of human cooperation. (shrink)

Numerous philosophers accept the differentiation condition, according to which one does not see an object unless one visually differentiates it from its immediate surroundings. This paper, however, sounds a sceptical note. Based on suggestions by Dretske (2007) and Gibson (2002 [1972]), I articulate two ‘principles of occlusion’ and argue that each principle admits of a reading on which it is both plausible and incompatible with the differentiation condition. To resolve the inconsistency, I suggest we abandon the differentiation condition.

Hofweber (Ontology and the ambitions of metaphysics, Oxford University Press, 2016) argues for a thesis he calls “internalism” with respect to natural number discourse: no expressions purporting to refer to natural numbers in fact refer, and no apparent quantification over natural numbers actually involves quantification over natural numbers as objects. He argues that while internalism leaves open the question of whether other kinds of abstracta exist, it precludes the existence of natural numbers, thus establishing what he calls “restricted nominalism” about (...) natural numbers. We argue that Hofweber’s internalism fails to establish restricted nominalism. Not only is his primary argument for restricted nominalism invalid, the analysis of quantification proposed threatens to collapse internalism into either a traditional form of error theory or realism.

I argue that there is tension in Wittgenstein’s position on trivialities (i.e. tautologies and contradictions) in the Tractatus, as it contains the following claims: (A) sentences are pictures; (B) trivialties are not pictures; (C) trivialities are sentences. A and B follow from the “picture theory” of language which Wittgenstein proposes, while C contradicts it. I discuss a way to resolve this tension in light of Logicality, a hypothesis recently developed in linguistic research. Logicality states that trivialities are excluded by the (...) grammar, and that under the right analysis sentences which look trivial are in fact contingent. The tools necessary to support Logicality, I submit, were not available to Wittgenstein at the time, which explains his commitment to C. I end the paper by commenting on some points of contact between analytic philosophy and the generative enterprise in linguistics which are brought into relief by the discussion. (shrink)

In recent years there has been a noticeable yet largely unacknowledged ‘pragmatic turn’ in the scientific realism debate, inspired in part by van Fraassen’s work on ‘epistemic stances’. Features of this new approach include: an ascent to the meta-level (the focus is not so much on whether scientific realism is true, but on the prior questions of the nature of the positions in this debate, how to decide whether to be a scientific realist, etc.); a reinterpretation of scientific realism and (...) anti-realism as (or as closely associated with) stances or frameworks, rather than theories or beliefs; a move away from the previously dominant empirical-explanatory (i.e. quasi-scientific or naturalistic) conception of scientific realism, anti-realism, and their justification; and a stress on the pragmatic and values-based elements in the debate. The traditional scientific realism debate is concerned with determining which position is true, or most epistemically justified. The new approach by contrast is concerned with determining which position best serves certain values, e.g. is most useful, fruitful, or otherwise prudentially preferable. In this paper we try to bring together the various strands in this new orientation, summarise its key features, contrast it with superficially similar but opposing views, and explore the similarities and differences among some of its adherents. Given we are advocates of the turn, we also offer a defence of the value and fruitfulness of this reconceptualization of the debate. (shrink)

An objection to shifty epistemologies such as subject-sensitive invariantism is that it predicts that agents are susceptible to guaranteed losses. Bob Beddor (Analysis, 81, 193–198, 2021) argues that these guaranteed losses are not a symptom of irrationality, on the grounds that forgetful agents are susceptible to guaranteed losses without being irrational. I agree that forgetful agents are susceptible to guaranteed losses without being irrational– but when we investigate why, the analogy with shifty epistemology breaks down. I argue that agents with (...) shifty epistemologies are susceptible to guaranteed losses in a way which is a symptom of irrationality. Along the way I make a suggestion about what it takes for an agent to be coherent over time. I close by offering a taxonomy of shifty epistemologies. (shrink)

The aim of the paper is to evaluate the prospects for an aesthetically informed assessment-sensitive semantic account of thick aesthetic predicates (TAPs) such as 'intense', 'sombre', ‘balanced’, ‘harmonious’, etc. We distinguish two meaning dimensions concerning TAPs, truth-conditional and use-conditional or expressive, and provide a dualist semantics that posits assessment sensitivity at both levels. Then we evaluate the extent to which assessment sensitivity is an apt rendition of aesthetic discourse involving TAPs. We distinguish between experiential TAPs (‘intense’, ‘sombre’) and theoretical TAPs (...) (‘balanced’, ‘dynamic’), and argue that there is evidence for a relativistic construal both at the truth-conditional and the expressive level for experiential TAPs, but not for theoretical TAPs. Thus, an upper bound is found on how much assessment sensitivity characterises aesthetic discourse. (shrink)

What exactly is the role of empirical beliefs in moral reflective equilibrium (RE)? And if they have a part to play, can changes in our empirical beliefs effectuate changes in the moral principles we adopt? Conversely, can empirical beliefs be adjusted in light of certain moral convictions? While it is generally accepted that empirical background theory is of importance to the method of wide reflective equilibrium (WRE), this article focuses on a different aspect, namely the role of empirical beliefs that (...) is intrinsic to the coherence relation of moral beliefs in any (narrow or wide) conception of RE. First, it is shown that in the application of RE, empirical beliefs are crucial to the procedure of matching principles to considered judgments. Changes in our empirical beliefs may therefore upset the relevant coherence relation and motivate changes in the moral principles we adopt. This more detailed account of the interplay between empirical and moral beliefs can help evaluate the overall philosophical appeal of RE. Finally, it is argued that, at least in WRE, the relation between empirical and moral beliefs need not be a one-way street, that is, moral convictions can provide us with some epistemic means of adjudicating between competing empirical descriptions of the world.

Epistemic reliabilism holds that a belief is justified if and only if it is produced by a reliable or truth-conducive process. I argue that reliabilism offers an epistemology for bounded rationality. This latter concept refers to normative and descriptive accounts of real-world reasoning instead of some ideal reasoning. However, as initially formulated, reliabilism involves an absolute, context-independent assessment of rationality that does not do justice to the fact that several processes are reliable in some reasoning environments but not in others, (...) as is widely reported in the cognitive sciences literature. I consider possible solutions to this problem. Resorting to ‘normality reliabilism’, a variant of the theory, is one; but I find it insufficient. Therefore, in addition, I propose to relativise the reliability assessment to reasoning environments. This novel version of reliabilism fits bounded rationality better than the original one does.

I introduce and discuss an underappreciated form of motivated cognition: motivational pessimism, which involves the biasing of beliefs for the sake of self-motivation. I illustrate how motivational pessimism avoids explanatory issues that plague other (putative) forms of motivated cognition and discuss distinctions within the category, related to awareness, aetiology, and proximal goals.

This paper develops a problem for conciliationism that is structurally similar to the self-undermining problem but which is immune to most of the solutions offered against it. A popular objection to conciliationism is that it undermines itself. Given the current disagreement among philosophers about conciliationism, conciliationism seems to require rejecting conciliationism. Adam Elga (2010) has influentially argued that this shows that conciliationism is an incoherent method. By recommending its own rejection, conciliationism recommends multiple, incompatible responses to the same body of (...) experience. Many have offered solutions to this problem, including Elga himself. However, there is another undermining problem. When a peer disagrees about their own peerhood, conciliationism can require the rejection of the peer’s peerhood. The result is that conciliationism recommends two incompatible responses to the same body of experience in a way that parallels the original self-undermining problem. But since many, if not all, of the proposed solutions to the original undermining problem depend on distinctive characteristics of conciliationism undermining itself, they cannot apply to a peer undermining themself. I illustrate this by dividing the solutions that have been offered against the self-undermining problem into two categories: self-exempting solutions and non-exempting solutions. I then show how the proposed solutions under each type do not extend to the peer-undermining problem. If that is right, then conciliationism is faced with a more difficult undermining problem than has been so far acknowledged. (shrink)

According to the cognitive model of psychopathology, maladaptive beliefs about oneself, others, and the world are the main factors contributing to the development and persistence of various forms of mental suffering. Therefore, the key therapeutic process of Cognitive Behavioral Therapy (CBT)—a therapeutic approach rooted in the cognitive model—is cognitive restructuring, i.e., a process of revision of such maladaptive beliefs. In this paper, I examine the philosophical assumptions underlying CBT and offer theoretical reasons to think that the effectiveness of belief revision (...) in psychotherapy is very limited. This is the case, I argue, because the cognitive model wrongly assumes that our body of beliefs is unified, while it is in fact fragmented. (shrink)

In a number of papers, Kit Fine introduced a theory of embodiment which distinguishes between rigid and variable embodiments, and has been successfully applied to clarify the ontological nature of entities whose parts may or may not vary in time. In particular, he has applied this theory to describe a process such as the erosion of a cliff, which would be a variable embodiment whose manifestations are the different states of erosion of the cliff. We find this theory very powerful, (...) and especially appropriate to capture the intuition that the same process may go on at different times. However, its formal principles have been subject to some criticisms, mainly concerning the mereological structure of a variable embodiment. Moreover, since the notion of variable embodiment is very general, simply saying that processes are variable embodiments is not enough to understand their ontological nature. To address these concerns, in this paper we proceed in two phases: first, we propose a revised version of Fine’s original theory adapted to the case of processes, which adopts a classical mereology instead of Fine’s hylomorphic mereology, and a temporalized constitution relation in place of Fine’s function of variable embodiment; second, we go deeper into the ontological nature of processes by revisiting the notions of homogeneity, intentionality, and telicity discussed in the literature, and propose an account based on ontological principles and not on semantic properties of predicates. This allows us to organize processes into a novel taxonomy based exclusively on their unity and individuation principles. (shrink)

Natural modalities are often analysed from an abstract point of view where they are associated with putative laws of nature. However, the way possibilities are represented in physics is more complex. Lagrangian mechanics, for instance, involves two different layers of modalities: kinematical and dynamical possibilities. This paper examines the status of these two layers, both in the classical and quantum case. The quantum case is particularly problematic: we identify four possible interpretive options. The upshot is that a close inspection of (...) the way possibilities are represented in physics could lead to new ways of thinking about natural modalities. (shrink)

Work in philosophy of mind often engages in descriptive phenomenology, i.e., in attempts to characterize the phenomenal character of our experience. Nagel’s famous discussion of what it’s like to be a bat demonstrates the difficulty of this enterprise (1974). But while Nagel located the difficulty in our absence of an objective vocabulary for describing experience, I argue that the problem runs deeper than that: we also lack an adequate subjective vocabulary for describing phenomenology. We struggle to describe our own phenomenal (...) states in terms we ourselves find adequately expressive. This paper aims to flesh out why our phenomenological vocabulary is so impoverished – what I call the impoverishment problem. As I suggest, this problem has both practical and philosophical import. After fleshing out the problem in more detail, I draw some suggestive morals from the discussion in an effort to point the way forward towards a solution. (shrink)

Deceptionism about lying is the view that all lies are intended to deceive. This view sits uneasily with some cases that seem to involve lies not intended to deceive. We call these lies bald-faced because the liar lies while believing that the hearer knows that they are lying. The most recent deceptionist argument put forward by Rudnicki and Odrowąż-Sypniewska (this journal) defends the view that all genuine bald-faced lies are intended to deceive some of their hearers. I argue that this (...) argument is interesting but problematic: its premises do not support the view that all bald-faced lies are intended to deceive but rather only that some people who bald-faced lie to institutions or large audiences intend to deceive someone. Also, genuine bald-faced lies addressed at institutions are intended to (non-deceptively) manipulate institutions rather than deceive anyone. (shrink)

This paper seeks to carve out a distinctive category of conspiracy theorist, and to explore the process of becoming a conspiracy theorist of this sort. Those on whom I focus claim their beliefs trace back to simply trusting their senses and experiences in a commonsensical way, citing what they take to be authoritative firsthand evidence or observations. Certain flat Earthers, anti-vaxxers, and UFO conspiracy theorists, for example, describe their beliefs and evidence this way. I first distinguish these conspiracy theorists by (...) contrasting them with another group that has recently received a lot of attention from the media, philosophers, and academics more broadly. I then dig more deeply into the nature of these conspiracy theorists’ epistemic self-understanding, in order to give an account of the process by which one becomes such a conspiracy theorist. I conclude with some takeaways and implications: first, I explore the implications of my account for whether these conspiracy theorists’ beliefs are rational; then, I argue that my account has practical takeaways about counteracting beliefs in misinformation, since strategies appropriate to this kind of conspiracy theorist may not be the same ones that are appropriate for other kinds.

Epidemiological models of the transmission of SARS-CoV-2 played an important role in guiding the decisions of policy-makers during the pandemic. Such models provide output projections, in the form of time -series of infections, hospitalisations, and deaths, under various different parameter and scenario assumptions. In this paper I caution against handling these outputs uncritically: raw model-outputs should not be presented as direct projections in contexts where modelling results are required to support policy -decisions. I argue that model uncertainty should be handled (...) and communicated transparently. Drawing on methods used by climate scientists in the fifth IPCC report I suggest that this can be done by: attaching confidence judgements to projections based on model results; being transparent about how multi-model ensembles are supposed to deal with such uncertainty; and using expert judgement to ‘translate’ model-outputs into projections about the actual world. In a slogan: tell me what you think (and why), not (just) what your models say. I then diffuse the worry that this approach infects model-based policy advice with some undesirably subjective elements, and explore how my discussion fares if one thinks the role of a scientific advisor is to prompt action, rather than communicate information.

To deal with memory-based modes of presentation I propose a couple of revisions to the standard criterion of difference for modes of presentation attributed to Frege. First, we need to broaden the scope of the criterion so that not merely the thoughts of a given subject at a given time may or may not involve the same way of thinking of some object, but also the thoughts of a subject at different times. Second, we need to ‘relativize’ the criterion of (...) difference to particular subjects in particular situations. Thanks to these revisions, we can make sense of Evans’ notion of a dynamic mode of presentation that persists through time despite lower-level changes. A dynamic mode of presentation is a complex mode of presentation involving several epistemically rewarding relations to the reference successively (in contrast to composite modes of presentation, which involve several epistemically rewarding relations simultaneously). I show how this idea can be cashed out in the mental file framework, and how, in that framework, we can provide a straightforward answer to the question: when is a mode of presentation based on a memory M the same as the mode of presentation based on the perception P from which the memory derives? The answer appeals to the distinction between anchored and unanchored memories. (shrink)

In order to explain that sentences containing empty definite descriptions are nevertheless true or false, Russell famously analyzes sentences of the form ‘The F is G’ as ‘There is exactly one F and it is G’. Against this it has been objected that Russell’s analysis provides the wrong truth-conditions when it comes to non-doxastic attitude ascriptions. For example, according to Heim, Kripke, and Elbourne (HKE), there are circumstances in which (1) is true and (2) is false. Hans wants the ghost (...) in his attic to be quiet tonight.Hans wants there to be exactly one ghost in his attic and for it to be quiet tonight. After all, the argument goes, unlike (2), (1) can be true without Hans wanting there to be exactly one ghost in his attic. Kaplan and Neale famously reply that the HKE objection presupposes that non-doxastic attitudes are closed under entailment, which they are not. For Rostworowski, on the other hand, the problematic principle used by the HKE objection is a substitutivity principle for non-doxastic attitude ascriptions. This is further supported by the fact that, as Elbourne points out, Russell’s analysis already leads to a problem similar to the HKE objection together with substitutivity alone. By questioning substitutivity for non-doxastic attitude ascriptions, Rostworowski tries to block both the HKE objection and Elbourne’s variant of the HKE objection. In this paper, I will argue that Russell’s analysis of definite descriptions leads to a variant of the HKE objection even in the context of doxastic attitude ascriptions. Since, as we will see, doxastic attitude ascriptions do not seem to suffer from the substitutivity problems discussed by Rostworowski in the context of non-doxastic attitude ascriptions, this will further exacerbate the problem for Russell’s analysis. I will then discuss the possibility to reject substitutivity for doxastic attitude ascriptions using a contextualist analysis of attitude ascriptions. However, we will see that, independent of whether we accept substitutivity for doxastic attitude ascriptions, a complete solution of the doxastic problem has to reject Russell’s analysis of the truth-conditions of sentences of the form ‘The F is G’. Concluding, I will show that, unlike Russell’s analysis, the Frege–Strawson analysis of definite descriptions, according to which a sentence of the form ‘The F is G’ presupposes that there is exactly one F, rather than asserting it, provides an explanation of the HKE objection, Elbourne’s variant of the HKE objection, and the doxastic problem presented in this paper. This will speak not only in favor of a Fregean analysis of definite descriptions, but also of a Fregean conception of propositions. (shrink)

When Kuhn first published his _Structure of Scientific Revolutions_ he was accused of promoting an “irrationalist” account of science. Although it has since been argued that this charge is unfair in one aspect or another, the early criticism still exerts an influence on our understanding of Kuhn. In particular, normal science is often characterized as dogmatic and uncritical, even by commentators sympathetic to Kuhn. I argue not only that there is no textual evidence for this view but also that normal (...) science is much better understood as being based on _epistemically justified_ commitment to a paradigm and as _pragmatic_ in its handling of anomalies. I also argue that normal science is an example of what I call Kuhn’s program of _revisionary rational reconstruction_. (shrink)

One particularly influential strand of the contemporary philosophical literature on the metaphysics of social institutions has been the collective acceptance approach, most prominently advocated by John Searle and Raimo Tuomela. The continuing influence of the collective acceptance approach has resulted in alternative accounts that either preserve a role for collective acceptance, or replace it with some other kind of mental state. I argue that this emphasis on the mental in the metaphysics of social institutions is a mistake. First, I raise (...) problems for the collective acceptance approach itself, then for pluralist approaches that preserve a role for collective acceptance, and finally for approaches that replace collective acceptance with individual mental states such as beliefs and intentions. Lest my arguments undermining these approaches to the metaphysics of social institutions seem to also undermine our ability to give such a metaphysics at all, I end by sketching an alternative approach: focusing only on observable behavior, with no role for mental states.

Scholarship in experimental jurisprudence has reported surprising findings about various concepts of legal significance: _acting intentionally_, _causation_, _consent_, _knowledge, recklessness_, _reasonableness,_ and _law_ itself. Often, these studies examine laypeople’s ordinary concepts and draw broader conclusions about legal experts’ concepts. This Article questions such inferences, from empirical findings about ordinary concepts to conclusions about the concepts of those with legal expertise. It presents a case study concerning what it means to act _intentionally._ An experiment examines intentionality judgments across four populations (N (...) = 774): laypeople, law students, non-law students, and United States judges. Legal training affected judgments in three ways that are consistent with the acquisition of a distinctive legal concept. This case study supports the Article’s broader claim: Laypeople’s ordinary concepts are not equivalent to experts’ legal concepts. The acquisition of legal concepts is an important form of legal expertise. (shrink)

We argue that two well-known examples (strawberry distribution and Konigsberg bridges) generally considered genuine cases of distinctively _mathematical_ explanation can also be understood as cases of distinctively _generic_ explanation. The latter answer resemblance questions (e.g., why did neither person A nor B manage to cross all bridges) by appealing to ‘generic task laws’ instead of mathematical necessity (as is done in distinctively mathematical explanations). We submit that distinctively generic explanations derive their explanatory force from their role in ontological unification. Additionally, (...) we argue that distinctively generic explanations are better seen as standardly mathematical instead of distinctively mathematical. Finally, we compare and contrast our proposal with the work of Christopher Pincock on abstract explanations in science and the views of Michael Strevens on abstract causal event explanations.

Conceptual engineers are always on the lookout for concepts that can be improved upon or replaced. Kevin Scharp has argued that the concept truth is inconsistent, and that this inconsistency thwarts its ability to serve in philosophical and scientific explanatory projects, such as developing linguistic theories of meaning. In this paper I present Scharp’s view about what makes a concept inconsistent, and why he believes that truth in particular is inconsistent. Then I examine the concepts that he suggests should replace (...) truth for various explanatory and expressive duties. I argue that those concepts are not up to the tasks for which they are posited, and so Scharp’s replacement methodology itself needs to be reengineered. (shrink)

What fixes the referents of episodic memories? While developed theories are lacking, it is generally assumed that the causal production of a memory, via memory traces, determines its referent. Recently, it has been pointed out that the “promiscuity” of memory traces poses a problem for this approach. Proposed solutions focus on finding some nonpromiscuous causal link. In this paper, I refine the problem posed by promiscuous memory traces and show that these solutions fail. By developing the question of mnemonic episodic (...) reference within the framework of informational signs, I argue that no pure “producer-side” theory of reference will work. The only solution, I argue, is to abandon pure producer-side theories for theories which appeal to consumer-side factors, i.e., factors concerning how referring signs are used. Once it is admitted that mnemonic episodic reference depends on consumer-side factors, the natural question is whether producer-side factors (i.e., causal production) play any role at all in mnemonic episodic reference. I conclude by outlining two possible pure consumer-side theories for mnemonic episodic reference, one based on the work of Imogen Dickie and one based on the work of Ruth Millikan. Both theories explain how the referents of episodic memories are fixed without any appeal to a causal link, and, hence, are compatible with “post-causal” theories of memory, like simulationism.

The method of reflective equilibrium is typically characterized as a process of two kinds of adjustments: hold fixed one’s current set of commitments/intuitions and adjust rules/principles to account for them, then hold fixed those rules while making adjustments to one’s set of commitments. Repeat until no further adjustments are required. Such characterizations ignore the role of precedent, i.e., information about the commitments and rules of others and how those might serve as guides in one’s own process of deliberation. In this (...) paper we develop a model that narrows in on a local part of a reflective equilibrium process in which a group of peer agents start with identical lists of commitments and work towards finding the rule that captures that set. If successful, we say they reach rest stop interpersonal convergence. The trouble is that, without precedent, reaching this convergence rests on implausible deterministic assumptions. We analyze how far the inclusion of a kind of soft precedent goes towards aiding the group in reaching said convergence when those assumptions are relaxed. (shrink)

The goal of this paper is to re-assess reflective equilibrium (“RE”). We ask whether there is a conception of RE that can be defended against the various objections that have been raised against RE in the literature. To answer this question, we provide a systematic overview of the main objections, and for each objection, we investigate why it looks plausible, on what standard or expectation it is based, how it can be answered and which features RE must have to meet (...) the objection. We find that there is a conception of RE that promises to withstand all objections. However, this conception has some features that may be unexpected: it aims at a justification that is tailored to understanding and it is neither tied to intuitions nor does it imply coherentism. We conclude by pointing out a cluster of questions we think RE theorists should pay more attention to. (shrink)

Various data from communication that does not occur face-to-face are taken to be problematic for Kaplan’s account of indexical expressions, as is the case with the so-called answering machine paradox. One fix, developed by Sidelle (1991) and Briciu (2018), is the remote utterance view: recording artifacts are means by which speakers perform utterances at a distance, just as by means of other artifacts agents performs other types of actions at a distance. This view has faced an important objection, namely that (...) remote utterances lead to Moorean paradoxes. In this paper, I defend the remote utterance view against this objection and further develop the view. I argue that worries about Moorean paradoxes can easily be dispelled if we take into consideration the artifactual nature of recording devices, their materiality, and the communicative affordances they bring about. In the first section, we’ll present the answering machine paradox and give a brief overview of the remote utterance view. The second section presents the objection against the view, while the third gives a detailed rejoinder to the objection. Answering this objection is important also because it allows us to explore some underdeveloped aspects of the remote utterance view. First, I will discuss how the theorist calibrates her model with the data she seeks to explain and predict. Secondly, I will argue that speech acts performed via recording devices have different felicity conditions than their oral counterparts. I conclude with a short discussion of some semantic and pragmatic consequences of the view. (shrink)

Brian Cutter (Analysis 77: 278-287, 2017) argues that one of the most prominent versions of the consequence argument—viz., Peter van Inwagen’s (An Essay on Free Will. Oxford University Press, 1983) ‘Third Formal Argument’—does not support an incompatibility thesis that every paradigmatic compatibilist would reject. Justin Capes (Thought 8: 50-56, 2019) concedes Cutter’s conclusion concerning van Inwagen’s Third Formal Argument and tries to meet the important challenge that Cutter issues at the end of his paper—viz., articulate a promising version of the (...) consequence argument whose conclusion is an incompatibility thesis that every paradigmatic compatibilist would reject. After arguing that Capes’s response to Cutter’s challenge fails, I meet Cutter’s challenge by presenting and discussing a version of the consequence argument that focuses on ordinary human agents in circumstances that are ordinary for human agents.

The paper disputes the common view which holds that to lie is, essentially, to assert a disbelieved proposition. It shows by reference to self-defeating prophecies that one can lie by asserting a believed proposition, and by reference to self-fulfilling prophecies that one can be truthful by asserting a disbelieved proposition. It concludes that lying is, essentially, asserting a proposition believed to be false conditionally on the occurrence of the assertion.

The widely accepted view states that an intention to deceive is not necessary for lying. Proponents of this view, the so-called non-deceptionists, argue that lies are simply insincere assertions. We conducted three experimental studies with false explanations, the results of which put some pressure on non-deceptionist analyses. We present cases of explanations that one knows are false and compare them with analogical explanations that differ only in having a deceptive intention. The results show that lay people distinguish between such false (...) explanations and to a higher degree classify as lies those explanations that are made with the intention to deceive. Non-deceptionists fail to distinguish between such cases and wrongly classify both as lies. This novel empirical finding indicates the need for supplementing non-deceptionist definitions of lying, at least in some cases, with an additional condition, such as an intention to deceive.

This paper discusses a novel response to two closely related regress arguments from Bolzano’s Theory of Science and Carroll’s What the Tortoise Said to Achilles. Bolzano’s argument aims to refute the thesis that full grounds must include propositions involving notions such as entailment, grounding or lawhood which link the respective grounds to their groundee. This thesis is motivated, Bolzano’s argument is reconstructed, and a response based on self-referential linking propositions is developed and defended against objections concerning self-reference and Curry’s paradox. (...) Finally, the idea is applied to a reading of Carroll’s dialogue and a corresponding solution to the so-called infinite regress problem of inference is proposed. (shrink)

Several promising approaches have been developed to represent conscious experience in terms of mathematical spaces and structures. What is missing, however, is an explicit definition of what a ‘mathematical structure of conscious experience’ is. Here, we propose such a definition. This definition provides a link between the abstract formal entities of mathematics and the concreta of conscious experience; it complements recent approaches that study quality spaces, qualia spaces, or phenomenal spaces; and it provides a general method to identify and investigate (...) structures of conscious experience. We hope that ultimately this work provides a basis for developing a common formal language to study consciousness. (shrink)

This paper concerns the semantics of coordinated if-clauses, as in (1)-(2). It is argued that the meanings of such sentences are explained straightforwardly on theories of conditionals that tie their non- monotonic behaviour to the if-clause itself (e.g. Schlenker 2004, but not theories that tie it to a (covert) modal operator (e.g. Kratzer 1981; 1991). Coordinated if-clauses are revealing of the fine-grained compositional semantics of conditionals.

Ground is all the rage in contemporary metaphysics. But what is its nature? Some metaphysicians defend what we could call, following Skiles and Trogdon (2021), the inheritance view: it is because constitutive forms of metaphysical explanation are such-and-such that we should believe that ground is so-and-so. However, many putative instances of inheritance are not primarily motivated by scientific considerations. This limitation is harmless if one thinks that ground and science are best kept apart. Contrary to this view, we believe that (...) ground is a highly serviceable tool for investigating metaphysical areas of science. In this paper, we defend a naturalistic version of the inheritance view which takes constitutive scientific explanation as a better guide to ground. After illustrating the approach and its merits, we discuss some implications of the emerging scientific conception for the theory of ground at large. (shrink)

Aristotelian naturalism (AN) holds that the norms governing the human will are special instances of a broader type of normativity that is also found in other living things: natural goodness and natural defect. Both critics and defenders of AN have tended to focus on the thorny issues that are specific to human beings. But some philosophers claim that AN faces other difficulties, arguing that its broader conception of natural normativity is incompatible with current biological science. This paper has three aims. (...) First, we consider a distinctive and nuanced critique of AN’s general understanding of natural normativity put forward by Tim Lewens. Second, after giving a defense of AN, we explore and evaluate Lewens’ proposed alternative view—Kantian projectivism about life forms. We present a problem for Kantian projectivism and suggest reasons for thinking that AN is, after all, the superior position. Finally, we clarify and explain how AN’s claims about life forms and our knowledge of them, relate to empirical observation and to contemporary biological science. (shrink)

In this paper, I argue that the Hole Argument can be formulated without using the notion of isomorphism, and for this reason it is not threatened by the criticism of Halvorson and Manchak (Br J Philos Sci, 2022. https://doi.org/10.1086/719193). Following Earman and Norton (Br J Philos Sci 38, pp. 515–525, 1987), I divide the Hole Argument into two steps: the proof of the Gauge Theorem and the transition from the Gauge Theorem to the conclusion of radical indeterminism. In the analaysis (...) of the first step, I argue that the Gauge Theorem does not rely on the notion of isomorphism but on the notion of the diffeomorphism-invariance of the equations of local spacetime theories; however, for this approach to work, the definition of local spacetime theories needs certain amendments with respect to Earman and Norton’s formulation. In the analysis of the second step, I postulate that we should use the notion of radical indeterminism instead of indeterminism simpliciter and that we should not decide in advance what kind of maps are to be used in comparing models. Instead, we can tentatively choose some kind of maps for this purpose and check whether a given choice leads to radical indeterminism involving empirically indistinguishable models. In this way, the use of the notion of isomorphism is also avoided in the second step of the Hole Argument. A general picture is that physical equivalence can be established by means of an iterative procedure in which we examine various candidate classes of maps, and, depending on the outcomes, we need to broaden or narrow these classes. The Hole Argument can be viewed as a particular instance of this procedure. (shrink)

According to the traditional view in the philosophy of logic facts of logic bear normative authority regarding how one ought to reason. Usually this is to mean that the relation of logical consequence between statements has some special relevance for how one’s beliefs should cohere. However, as I will argue in this article, this is just one way in which logic is normative for reasoning. For one thing, belief is not the only kind of mental state involved in reasoning. Besides (...) adopting and revising beliefs, rational agents pose and resolve questions. For another thing, the consequence relation of classical logic can be conservatively extended such that it includes logical relations between questions as well. Therefore, there is an argument to be made that not only the inference of new beliefs from extant beliefs but also the process of raising additional questions falls under the normative authority of logic. Accordingly, a nuanced account of the normativity of logic presents itself, which convincingly deals with problems such as clutter-avoidance and the paradox of the preface. (shrink)

Structuralism in philosophy of mathematics has largely focused on arithmetic, algebra, and basic analysis. Some have doubted whether distinctively structural working methods have any impact in other fields such as differential equations. We show narrowly construed structuralism as offered by Benacerraf has no practical role in differential equations. But Dedekind’s approach to the continuum already did not fit that narrow sense, and little of mathematics today does. We draw on one calculus textbook, one celebrated analysis textbook, and a monograph on (...) the Navier–Stokes equation to show structural methods like Dedekind’s have long been central to differential equations, and have philosophically respectable ontology and epistemology.

Recent theories of remembering and of reference (or singular thought) have de-emphasised the role causation was thought to play in mid- to late-twentieth century theorising. According to postcausal theories of remembering, such as simulationism, instances of the psychofunctional kind _remembering_ are not, in principle, dependent on appropriate causal chains running from some event(s) remembered to the occurrence of remembering. Instead they depend only on the reliability, or proper functioning, of the cognitive system responsible for their production. According to broadly reliabilist (...) accounts of _singular thought_, such thought is not, in principle, dependent on causal chains running from the object(s) of thought to the occurrence of thinking. Despite this common trend, accounts of the two phenomena have been pursued separately. In this paper, we argue that the two lines of research can profitably converge to address a neglected question: what enables occurrences of remembering to _refer_ to particular events, and what determines _which_ event a given occurrence of remembering refers to? We motivate and present a reliabilist account of reference-fixing for postcausal theories of remembering, focusing in particular on simulationism. We then show that this account draws attention to the possibility of _referential mnemic confabulation:_ cases where the reliability requirement for reference is met despite the improper functioning of the episodic construction system. We suggest that this makes sense of some underdiscussed phenomena described in the empirical literature on confabulation and argue that our reliabilist account of mnemic reference-fixing accommodates these more naturally than could causal theories of remembering.

This paper critically examines and evaluates Yacin Hamami’s reconstruction of the standard view of mathematical rigor. We will argue that the reconstruction offered by Hamami is premised on a strong and controversial epistemological thesis and a strong and controversial thesis in the philosophy of mind. Secondly, we will argue that Hamami’s reconstruction of the standard view robs it of its original philosophical rationale, i.e. making sense of the notion of rigor in mathematical practice.

Recent debates about disagreement’s significance have largely focused on its _epistemic_ significance. However, given how much attention has already been paid to its epistemic significance, we might well wonder: what significance might disagreement have when we consider other related normative domains? And, in particular, what significance might it have when we consider the broader _domain of inquiry,_ or what some thinkers have called either the “zetetic” or “erotetic” domain? In response, this paper suggest three things. Firstly, it suggests how we (...) might clarify the relations among the epistemic, erotetic, and zetetic domains of normativity, given their potential differences and incompatibilities. Then, it suggests that disagreement’s significance within inquiry can either be tied to erotetic norms or to either of two sorts of zetetic norms: vindication-directed or possession-directed norms. And finally, it suggests preferred answers to the question of what disagreement’s _distinctly_ zetetic significance might be, given the participating inquirers’ ordinarily-conceived zetetic standings and how their sets of dialectically accessible evidence might compare.

This paper offers an alternate solution to the puzzle of transformative experience raised by Paul (2014), through an appeal to Arthur Schopenhauer’s concept of the _acquired character_, which speaks to the intuition that authenticity entails a notion of the ‘self-as-guide’ (Rivera et al., 2019 ). On Paul’s solution to the puzzle, transformative decisions may be made authentically by adopting a meta-preference concerning personal transformation, such that the self is constituted after a decision is made. Yet when comparing Paul’s account of (...) authenticity to that of Somogy Varga’s (2012), we see that the former is too formal in that it neglects certain requirements of personal identity-formation, which Varga defines as wholehearted commitment based in strong evaluation. However, in defining these requirements as such, Varga’s account of authenticity is unequipped to adequately address the puzzle of transformative experience. Varga’s account further falls short with respect to specifying sufficient criteria for personal fitness, as Rings (2017) argues. In connection with this deficiency, Varga’s account also does not fully reckon with the threat of manipulation, given the possibility of egoistically driven self-deception in conjunction with oppressive social conditions. I argue that with the aim of character acquisition via acts of subjective contemplation, the authenticity of transformative decisions can be understood at least partly in terms of self-discovery. To expand on authenticity’s ethical dimension, as first introduced by Varga, in a way that is compatible with this established dimension of self-discovery, and with the help of Christopher Gill’s (1996) analysis of an ancient Greek conception of personhood, I suggest that we conceive of authenticity also as a process of value-interpretation, while employing a concept of the self that I will refer to as the _metapersonal_. This process is congruent with a metapersonal self in so far as it is aimed at defining and clarifying the human good in general, from within a community whose fundamental ethical demand consists of maximizing mutual and reciprocal benefit.

Naïve Realism claims that the Phenomenal Character of perception is constituted by the mind-independent objects one perceives. According to this view, the Phenomenal Character of perception is object-dependent: experiences of different objects have different Phenomenal Characters, even if those objects are qualitatively identical. Proponents of Naïve Realism often defend this conception by arguing that it is necessary to accommodate the cognitive role of perceptual experience. John Campbell has presented the most influential version of this argument, according to which only an (...) object-dependent conception of the Phenomenal Character of experience can explain its epistemic role—how (conscious) perception ‘justifies’ the patterns of inference that reflect our conception of mind-independence. In this paper, I argue that Campbell’s argument is unsound. First, I reconstruct the relevant patterns and argue that, independently of one’s conception of Phenomenal Character, perceptual experience does not ‘justify’ them in the way Campbell intends—by making their validity transparent to the subject. Second, I suggest that perception justifies those patterns by justifying their premises. I argue that a Representationalist, object-independent conception of its Phenomenal Character is at least as well suited as an object-dependent one to explain how this is possible. This undermines one of the main motivations to endorse a Naïve Realist, object-dependent account of the Phenomenal Character of perception. (shrink)

It has been argued that nonreductive physicalism’s problems with mental causation disappear if we abandon the intuitive but naïve production-based conception of causation in favor of one based on counterfactual dependence and difference-making. In recent years, this response has been thoroughly developed and defended by James Woodward, who contends that Kim’s causal exclusion argument, widely thought to be the most serious threat to nonreductive mental causation, cannot even be given a coherent formulation within Woodward’s preferred interventionist framework. But Woodward has, (...) even more recently, defended a pair of necessary conditions on mental causation and higher-order causation more generally, and it is here that the interventionist framework proves less friendly to nonreductive mental causation. Functionalism is arguably the most important species of nonreductive physicalism concerning specifically mental properties, but, as I argue, functional properties fail both of Woodward’s tests of causal relevance, one of them in two different ways. The problem, moreover, seems unique to functionalism, for other types of higher-order properties appear to pass Woodward’s tests. If functionalism faces defeat even in such friendly territory, its problems with mental causation are not an artifact of naïve metaphysics. They run deep. (shrink)

In a recent series of papers, Timothy Williamson argues that one can reach Edmund Gettier’s conclusion that the justified-true-belief (JTB) theory of knowledge is insufficient for knowledge by constructing Gettier cases in the framework of epistemic logic. In this paper, I argue, however, that Williamson’s Gettier cases in the framework of epistemic logic crucially turn on an assumption that the JTB theorist can plausibly and justifiably reject. In particular, I argue that it is rational for the JTB theorist to reject (...) Williamson’s preferred epistemic accessibility relation in favor of one for which Gettier cases in epistemic logic do not arise. Thus, I conclude that Williamson’s Gettier cases in epistemic logic do not genuinely threaten the tripartite theory of knowledge. (shrink)

According to ‘orthodox’ representationalism, perceptual states possess constitutive veridicality (truth, accuracy, or satisfaction) conditions. Typically, philosophers who deny orthodox representationalism endorse some variety of anti-representationalism. But we argue that these haven’t always been, and needn’t continue to be, the only options. Philosophers including Descartes, Malebranche and Helmholtz appear to have rejected orthodox representationalism while nonetheless endorsing perceptual representations of a fundamentally practical kind not captured by orthodox representationalism. Moreover, we argue that the perceptual science called on by contemporary philosophers to (...) defend orthodox representationalism instead motivates a return to this older view, and we suggest that contemporary philosophers may conceptualize fundamentally practical perceptual representations as _‘de agendo’_ representations, a species of representation that has constitutive appropriateness rather than veridicality conditions.

Formal methods for representing the characteristic features of organic development and growth make it possible to map the large-scale teleological structure of organic activity. This provides a basis for semantically evaluating, or providing a theory of meaning for, talk of organic activity as purposive. For the processes of organic generation and growth are subjunctively robust under a variety of influences characteristic for the kind or species in question, and these subjunctive conditions can be displayed in a two-dimensional array. After motivating (...) and introducing this array, I use its two dimensions to partially account for features of the purposiveness characterizing two sets of exemplars of the plant and animal kingdoms: ferns and cacti, and cheetah and gazelle. The result is a formal framework for interpreting talk of organic activity as purposive, able to be adapted to a range of research traditions in the philosophy of language and the philosophy of biology.

Deep learning (DL) is a statistical technique for pattern classification through which AI researchers train artificial neural networks containing multiple layers that process massive amounts of data. I present a three-level account of explanation that can be reasonably expected from DL models in cognitive neuroscience and that illustrates the explanatory dynamics within a future-biased research program (Feest Philosophy of Science 84:1165–1176, 2017 ; Doerig et al. Nature Reviews: Neuroscience 24:431–450, 2023 ). By relying on the mechanistic framework (Craver Explaining the (...) brain: Mechanisms and the mosaic unity of neuroscience. Clarendon, 2007 ; Stinson Eppuor si muove: Doing history and philosophy of Science with Peter Machamer. Springer, 2017, The Routledge Handbook of the computational mind. Routledge, 2018 ), I develop an account that corresponds to the stages of mechanism discovery, i.e., our shifting epistemic position and epistemic goals, and propose a representative model for each level. Generic, theoretical DL models at _Level 1_ address the general features of a cognitive phenomenon through exploration and provide us with how-possibly explanations. On the other hand, DL models at _Level 2_ either identify the interaction between the features or represent the epistemic stage when the researcher is still unsure if the modeled features are crucial or arbitrary. These models should provide us with how-plausibly explanations. Finally, specific DL models of specific brain areas, i.e., ersatz models filled with relevant cognitive and neuroscientific details, are at _Level 3_. At this level, a researcher can advance how-actually explanations of cognitive phenomena. The main strength of this account is that it elucidates both _global explanatory dynamics_ and _local explanatory dynamics_ (cf. Dresow Synthese 199:10441–10474, 2021 ). The former occurs when the transition between levels happens in accordance with the process of obtaining more details about a particular cognitive phenomenon through multiple DL models. The latter, meanwhile, involves cases in which the transition between levels takes place within a single DL model by elucidating internal mechanisms (e.g., using Explainable AI techniques for rendering models more transparent).

Reductionism about testimony has become less popular as philosophers have uncovered our epistemic dependence on others. Meanwhile, both non-reductionism and the interpersonal view face a challenge from gullibility. Surprisingly, the concept of gullibility has not been sustainedly examined. The primary goal in this paper is to propose an analysis of gullibility. After some introductory remarks, we begin this paper by discussing an account of gullibility in terms of insensitivity to defeaters. We argue that this account cannot accommodate cases where agents (...) are gullible. We, therefore, offer a dispositional account of gullibility. In so doing, we show how gullibility differs from other epistemic vices vis-à-vis its interpersonal features. We also discuss how treating gullibility as an intellectual vice has salient implications for the debate between reductionists and non-reductionists about gullibility. (shrink)

This paper defends a reading of Wittgenstein’s philosophy of mathematics in the Lectures on the Foundation of Mathematics as a radical conventionalist one, whereby our agreement about the particular case is constitutive of our mathematical practice and ‘the logical necessity of any statement is a direct expression of a convention’ (Dummett 1959, p. 329). -/- On this view, mathematical truths are conceptual truths and our practices determine directly for each mathematical proposition individually whether it is true or false. Mathematical truths (...) are thus not consequences of a prior adoption of a convention or rules as orthodox conventionalism has it. -/- The goal of the paper is not merely exegetical, however, and argues that radical conventionalism can withstand some of the most difficult objections that have been brought forward against it, including those of Dummett himself, and thus that radical conventionalism has been prematurely excluded from consideration by philosophers of mathematics.

Beliefs based on pernicious ideology are widespread, and they often have harmful consequences. Attempts to solve the problems these beliefs cause could benefit from epistemological work on them, so it is heartening to see more epistemologists turning to study ideological beliefs. In this paper, I discuss one recent approach, radical epistemology, which has two aims: (1) offering structural explanations of epistemic justification and (2) putting these explanations to work in opposing ideology. While I share radical epistemologists’ opposition to pernicious ideology, (...) I argue that their position is untenable because it gives rise to a vicious circularity. Its core commitment maintains that theorists’ choice between competing epistemological theories should be guided by their moral and political commitments. These commitments themselves, however, are susceptible to reasonable disagreement and thus stand in need of defense. To defend them, radical epistemologists must employ the very theories those commitments are supposed to undergird. I call this _the problem of theory choice_ and conclude that radical epistemologists cannot solve it. But we shouldn’t despair: the time-honored tools of _non_-radical epistemology offer all we need to successfully theorize about and combat bad ideology. (shrink)

The Aristotelian view of universals, according to which each universal generically depends for its existence on its instantiations, has recently come under attack by a series of ground-theoretic arguments. The last such arguments, presented by Raven, promises to offer several significant improvements over its predecessors, such as avoiding commitment to the transitivity of ground and offering new reasons for the metaphysical priority of universals over their instantiations. In this paper, we argue that Raven's argument does not effectively avoid said commitment (...) and that Raven's new reasons fail. Moreover, we present a novel ground-theoretic interpretation of the Aristotelian view, referred to as strong immanence, and introduce a new argument against the Aristotelian view, intended to sidestep any commitment to the transitivity of ground.

This paper aims to flesh out the celebrated notion of reflective equilibrium within a probabilistic framework for epistemic rationality. On the account developed here, an agent's attitudes are in reflective equilibrium when there is a certain sort of harmony between the agent's credences, on the one hand, and what the agent accepts, on the other hand. Somewhat more precisely, reflective equilibrium is taken to consist in the agent accepting, or being prepared to accept, all and only claims that follow from (...) a maximally comprehensive theory that is more probable than any other such theory. Drawing on previous work, the paper shows that when an agent is in reflective equilibrium in this sense, the set of claims they accept or are prepared to accept is bound to be logically consistent and closed under logical implication. The paper also argues that this account can explain various features of philosophical argumentation in which the notion of reflective equilibrium features centrally, such as the emphasis on evaluating philosophical theories holistically rather than in a piecemeal fashion.

Daniel Isaacson has advanced an epistemic notion of arithmetical truth according to which the latter is the set of truths that we grasp on the basis of our understanding of the structure of natural numbers alone. Isaacson’s thesis is then the claim that Peano Arithmetic (PA) is the theory of finite mathematics, in the sense that it proves all and only arithmetical truths thus understood. In this paper, we raise a challenge for the thesis and show how it can be (...) overcome. We introduce the concept of purity for theories of arithmetic: a theory of arithmetic is pure when it only proves arithmetical truths. Then, we argue that, under Isaacson’s thesis, some PA-provable truths—including transfinite induction claims for infinite ordinals and some consistency statements—are seemingly not arithmetical in Isaacson’s sense, and hence that Isaacson’s thesis might entail the impurity of PA. Nonetheless, we conjecture that the advocate of Isaacson’s thesis can avoid this undesirable consequence: the arithmetical nature, as understood by Isaacson, of all contentious PA-provable statements can be justified. As a case study, we explore how this is done for transfinite induction claims with infinite ordinals below ε0. To this end, we show that the PA-proof of such claims employs exclusively resources from finite mathematics, and that ordinals below ε0 are finitary objects despite being infinite. (shrink)

While the Value-Free Ideal (VFI) had many precursors, it became a solidified bulwark of normative claims about scientific reasoning and practice in the mid-twentieth century. Since then, it has played a central role in the philosophy of science, first as a basic presupposition of how science should work, then as a target for critique, and now as a target for replacement. In this paper, we will argue that a narrow focus on the VFI is misguided, because the VFI coalesced in (...) the midst of other important shifts in the relationship between science and society. In particular, the mid-twentieth century saw the acceptance of the “social contract for science,” a tacit agreement between scientists and government officials, and more broadly between science and society. It was built around three core concepts: a distinction between basic and applied science, a conception of scientific freedom that limited social responsibility for scientists, and a justification for public funding of basic science in the form of the linear model. Within the conceptual framework of the social contract for science, it is clearer both (1) why the VFI was adopted, (2) why it is difficult to replace the VFI within the old social contract, and (3) how we need to revise the social contract for science in order to replace the VFI.

Memories can be accurate or inaccurate. They have, then, accuracy conditions. A reasonable picture of the accuracy conditions of a memory is that a memory is accurate just in case the reference of a memory satisfies the information provided by the memory. But how are the references of our memories determined exactly? And what are the accuracy conditions of memories, given their references? In this paper, I argue that the notion of accuracy conditions for memories is ambiguous. There are two (...) types of conditions which can be plausibly construed as accuracy conditions for memories. I motivate this idea by using some resources from two-dimensional semantics. The outcome of applying two-dimensionalism to memory is that memories have two kinds of accuracy conditions. In both cases, causal relations play an important role in the framing of those conditions. But the role is quite different in each case. For one type of accuracy conditions, the causal relations which produce a memory play the role of fixing the reference of that memory. For the other type of accuracy conditions, the causal relations which produce a memory become part of the information which needs to be satisfied by the reference of the memory for it to be accurate. However, in both cases, the picture according to which a memory is accurate just in case the reference of a memory satisfies the information provided by the memory reemerges as being correct, though for interestingly different reasons.

General epistemic polarization arises when the beliefs of a population grow further apart, in particular when all agents update on the same evidence. Epistemic factionalization arises when the beliefs grow further apart, but different beliefs also become correlated across the population. I present a model of how factionalization can emerge in a population of ideally rational agents. This kind of factionalization is driven by probabilistic relations between beliefs, with background beliefs shaping how the agents’ beliefs evolve in the light of (...) new evidence. Moreover, I show that in such a model, the only possible outcomes from updating on identical evidence are general convergence or factionalization. Beliefs cannot spread out in all directions: if the beliefs overall polarize, then it must result in factionalization. (shrink)

I argue that there are different orders of mechanisms with different constitutive relevance and individuation conditions. In common first-order mechanistic explanations, constitutive relevance norms are captured by the matched-interlevel-experiments condition (Craver et al. (2021) Synthese 199:8807–8828). Regarding individuation, we say that any two mechanisms are of the same type when they have the same concrete components performing the same activities in the same arrangement. By contrast, in higher-order mechanistic explanations, we formulate the decompositions in terms of generalized basic components (GBCs). (...) These GBCs (e.g., logic gates) possess causal properties that are common to a set of physical systems. Mechanistic explanations formulated in terms of GBCs embody the epistemic value of horizontal integration, which aims to explain as many phenomena as possible with a minimal amount of abstract components (Wajnerman Paz (2017a) Philos Psychol 30:213–234). Two higher-order mechanisms are of the same type when they share all the same GBCs, and they are organized as performing the same activities with the same interactions. I use this notion of mechanistic order to enhance the mechanistic account of computation (MAC) and provide an account of the epistemic norms of computational explanation and the nature of medium-independent functional properties and mechanisms. Finally, I use these new conceptual tools to address four criticisms of the MAC. (shrink)

Surveying and criticising attitudes towards the role and strength of the iterative conception of set—widely seen as the justificatory basis of Zermelo-Fraenkel set theory with Choice—this paper highlights a tension in both contemporary and historic accounts of the iterative conception’s justificatory role: on the one hand its advocates wish to claim that it justifies ZFC, but on the other hand they abstain from stating whether the preconditions for such justification exists. Expanding the number of axioms that the conception is standardly (...) charged with failing to justify, in the forms of the Emptyset and Powerset, this paper aims to extend the critique that the iterative conception does not justify ZFC to its subsystems. Exploring the historic and contemporary relationship between the iterative conception and set theory, the paper then attempts to defuse strategies that avoid the problems of intrinsic justification by weakening the iterative conception’s role to the ‘motivational’ or ‘heuristic’ by showing that what the iterative conception has been seen to motivate has changed over time. It is suggested that the conjunction of these arguments seriously weakens the programme of reasoning on an ‘atheoretic’ notion of set. (shrink)

This paper empirically investigates whether people’s implicit decision theory is more like causal decision theory or more like a non-causal decision theory (such as evidential decision theory). We also aim to determine whether implicit causalists, without prompting and without prior education, make a distinction that is crucial to causal decision theorists: preferring something _as a news item_ and preferring it _as an object of choice_. Finally, we investigate whether differences in people’s implicit decision theory correlate with differences in their level (...) of _future bias_: the preference for positively valenced events to be located in the future and not the past, and negatively valenced events to be located in the past and not the future. We find that people are overwhelmingly non-causalists. We also find that implicit causalists _do not_ make the distinction between news items and objects of choice, and that there is little to no correlation between people’s future bias and their implicit decision theory. We end by discussing the philosophical upshots of this work. (shrink)

In this paper we examine titles of early modern German dissertations with regard to their ‘interdiscplinarity’, challenging the established consensus that interdisciplinarity evolved only in the 18th century. Based on the construction and analysis of a co-occurrence network of 909 dissertation titles published in the 17thc entury it can be shown that various dimensions of early modern interdisciplinarity should be distinguished. This concerns dissertations that connect philosophical disciplines to the ‘higher’ faculties of the early modern university (theology, jurisprudence, medicine) as (...) well as titles that connect theoretical and practical subdisciplines of philosophy itself. We also observe that the emerging disciplines of historiography and philology seem to play a prominent role in the emergence of early modern interdisciplinarity. On a structural level it seems to be misguided to construe the early modern system of knowledge as a ‘tree’. It rather seems that relations betweeen disciplines in this period exhibit both tree-like and lattice-like features. (shrink)

If contextual values can play necessary and beneficial roles in scientific research, to what extent should science communicators be transparent about such values? This question is particularly pressing in contexts where there appears to be significant resistance among some non-experts to accept certain scientific claims or adopt science-based policies or recommendations. This paper examines whether value transparency can help promote non-experts’ warranted epistemic trust of experts. I argue that there is a prima facie case in favor of transparency because it (...) can promote four conditions that are thought to be required for epistemic trustworthiness. I then consider three main arguments that transparency about values is likely to be ineffective in promoting such trust (and may undermine it). This analysis shows that while these arguments show that value transparency is not sufficient for promoting epistemic trust, they fail to show that rejecting value transparency as a norm for science communicators is more likely to promote warranted epistemic trust than a qualified norm of value transparency (along with other strategies). Finally, I endorse a tempered understanding of value transparency and consider what this might require in practice. (shrink)

One of the main obstacles for panpsychism, the view that consciousness is fundamental and ubiquitous, is the difficulty of explaining how simple subjects could combine to form complex subjects. Known as the subject combination problem, it poses a possibly insurmountable challenge to the view. In this paper, I will assume that this challenge cannot be overcome and instead present a version of panpsychism that completely avoids talk of combination. Inspired by Gottfried Wilhelm Leibniz’s metaphysics of monads, I will focus on (...) a relational explanation of how simple subjects could constitute complex experiences, without them having to combine in virtue of their subjectivity. I call this view _monadic panpsychism_. Additionally, my proposal will not rely on emergence and so it will circumvent problems commonly faced by emergentist accounts. As I will argue, monadic panpsychism is preferable to combinatory and emergentist panpsychism because it faces a significantly less worrisome set of objections. Apart from being unaffected by the seemingly insuperable issue of subject combination, I will demonstrate that monadic panpsychism also has tools to address other kinds of the combination problem. That alone justifies the need for a new formulation of panpsychism, one which faces unique difficulties but also offers unique solutions. (shrink)

Pragmatist responses to skepticism about empirical justification have mostly been underwhelming, either presupposing implausible theses like relativism or anti-realism, or else showing our basic empirical beliefs to be merely psychologically inevitable rather than rationally warranted. In this paper I defend a better one: a modified version of an argument by Wilfrid Sellars that we are pragmatically warranted in accepting that our perceptual beliefs are likely to be true, since their likely truth is necessary for the satisfaction of our goal of (...) effective agency. On the version of the argument I defend, the great good for human life of control over our empirical circumstances renders our goal of effective agency reasonable. But only if our perceptual beliefs are likely to be true—and only if we accept that this is so, assuming it as a premise for inference and a guide for action—will the success of our actions be due to our effective agency, not mere luck. Since we’re warranted in taking the necessary means to our reasonable ends, we’re warranted in accepting that our perceptual beliefs are generally justified, and so that skepticism about empirical justification is false.

Functional reductionism characterises inter-theoretic reduction as the recovery of the upper-level behaviour described by the reduced theory in terms of the lower-level reducing theory. For instance, finding a statistical mechanical realiser that plays the functional role of thermodynamic entropy allows for establishing a reductive link between thermodynamics and statistical mechanics. This view constitutes a unique approach to reduction that enjoys a number of positive features, but has received limited attention in the philosophy of science. -/- This paper aims to clarify (...) the meaning of functional reductionism in science, with a focus on physics, to define both its place with respect to other approaches to reduction and its connection to ontology. To do so, we develop and explore two alternative frameworks for functional reduction, called Syntactic Functional Reductionism and Semantic Functional Reductionism. They represent two different possible stances on the view that expand and improve the basic functional reductionist approach along different lines, and make clear how the approach works in practice. The former elaborates on David Lewis’ account, is connected with the syntactic view of theories, is committed to a logical characterisation of functional roles, and is embedded within Nagelian reductionism. The latter adopts a semantic view of theories, spells out functional roles mainly in terms of mathematical roles within the models of theories, and is expressed in terms of the related structuralist approach to reduction. The development of these frameworks has the final goal of advancing functional reductionism, to make it a fully-fledged alternative account for reduction in science. (shrink)

Among the areas of knowledge that the method of reflective equilibrium (RE) has been applied to is that of logical validity. According to RE in logic, we come to be justified in believing a (deductive) logical theory in virtue of establishing some state of equilibrium between our initial judgements over the validity of specific (natural language) arguments and the logical principles which constitute our logical theory. Unfortunately, however, while relatively popular, RE with regards to logical theorizing is underspecified. In particular, (...) it’s unclear what constitute: (1) the relevant logical “data”, (2) logical theories, so that they can be suitably tested, and (3) the mechanisms under which such theories are tested. Considering the various options for how to interpret the position, we argue that in order to be workable the advocate of RE about logic must embrace what we call an _operationalised_, _wide_ and _communal_ version of RE with a _rich_ understanding of logical theories. Fortunately for the advocate of RE, there is an available account of logic’s epistemology which possesses just these properties, _logical predictivism_. However, equally unfortunately, logical predictivism commits the advocate of RE to certain further claims that they have historically been weary of holding. Consequently, it is unclear whether RE about logic itself is a viable proposal, or rather a similar but distinct epistemology of logic. (shrink)

This paper deals with the nature of trust in science. Understanding what appropriate trust in science is and why it can reasonably break down is important for improving scientists’ trustworthiness. There are two different ways in which philosophers of science think about trust in science: as based on objectivity or as based on shared values. Some authors argue that objectivity actually grounds mere reliance, not genuine trust. They draw on a distinction that philosophers of trust following Annette Baier have made (...) with respect to interpersonal trust, where genuine trust has some normative element to it that is missing in cases of mere reliance. However, I will show that there are plural forms of trust in science: Both objectivity and shared values ground trust in science in a normative sense. I will link the trust in science debate to the literature on interpersonal trust. This is significant in that, beyond references to Baier, there is little connection between both areas of philosophy. In a pluralist reading, different trust accounts help to identify the normative elements involved in different kinds of trust in science. (shrink)

Accuracy-first epistemologists argue that rational agents have probabilistically coherent credences. But why should we care, given that we can’t help being incoherent? A common answer: probabilistic coherence is an ideal to be approximated as best one can. De Bona (in: Philos Sci 84(2), 189–213, 2017) and Staffel (in: Unsettled thoughts: a theory of degrees of rationality, Oxford University Press, 2019) show how accuracy-firsters can spell out this answer by adopting an appropriate notion of approximate coherence. In this essay, I argue (...) that De Bona and Staffel’s proposal is not entirely satisfactory, because it does not show whether, or why, it’s generally better to be more rather than less approximately coherent from an accuracy-first perspective. To address this point, I give a characterisation of their notion of approximate coherence in terms of accuracy. This shows that accuracy-firsters should maintain that more approximately coherent credences are better than less approximately coherent ones _if and only if_ they accept that it’s better to miss out on less rather than more guaranteed accuracy.

People with bad beliefs — roughly beliefs that conflict with those of the relevant experts and are maintained regardless of counter-evidence — are often cast as bad believers. Such beliefs are seen to be the result of, e.g., motivated or biased cognition and believers are judged to be epistemically irrational and blameworthy in holding them. Here I develop a novel framework to explain why people form bad beliefs. People with bad beliefs follow the social epistemic norms guiding how agents are (...) supposed to form and share beliefs within their respective communities. Beliefs go bad because these norms aren’t reliably knowledge-conducive. In other words, bad beliefs aren’t due to bad believers but due bad social epistemic norms. The framework also unifies different explanations of bad beliefs, is testable and provides distinct interventions to combat such beliefs. The framework also helps to capture the complex and often contextual normative landscape surrounding bad beliefs more adequately. On this picture, it’s primarily groups that are to be blamed for bad beliefs. I also suggest that some individuals will be blameless for forming their beliefs in line with their group’s norms, whereas others won’t be. And I draw attention to the factors that influence blameworthiness-judgements in these contexts. (shrink)

Infinitism is often presented as a rival to foundationalism and coherentism as available answers to the epistemic regress problem. The most prominent contemporary defense of infinitism, due to Peter Klein, rests on the notion that an agent can perpetually amplify the justification for her belief insofar as they are able to iteratively answer an interlocutor’s questions why the proffered grounds for their belief should count as providing justification for that belief. We show that this argument does not offer any basis (...) for preferring infinitism over foundationalism and coherentism, because those views are able to accommodate the insight that justification for a belief can be continually amplified. Klein’s argument for infinitism thus falls short of its aspirations of proving that infinitism qua rival of foundationalism and coherentism is the most credible solution to the epistemic regress problem.

Reference is a basic feature of human language. A much debated question in the scholarship on animal communication and language evolution is whether traces of the human capacity for reference can be found in animals too. Do animals refer to things with their signals in the manner that humans do? Or is reference something that is unique to human communication? Answers to these questions have shifted significantly over the years and remain contentious. In this paper, I start by reconstructing and (...) critically analysing three influential discussions of the ways in which animal signals refer: the theory of functional reference (Marler, Evans and Hauser, 1992), Wheeler and Fischer (2012)’s meaning attribution framework, and Scarantino (2013)’s revised definition of functional reference. I show that functional reference, both in its traditional and revised version, as well as the meaning attribution framework, fail to adequately characterise animal reference as an evolutionary precursor of linguistic reference. This is because they all overlook at least some aspects of the psychology of signal production. Nonetheless, drawing on Crockford et al. (2012, 2017), I show that we can plausibly interpret chimpanzees’ alert hoos as a case of intentional, human-like animal reference. (shrink)

When P(E) > 0, conditional probabilities P(H|E)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(H|E)$$\end{document} are given by the ratio formula. An agent engages in ratio conditionalization when she updates her credences using conditional probabilities dictated by the ratio formula. Ratio conditionalization cannot eradicate certainties, including certainties gained through prior exercises of ratio conditionalization. An agent who updates her credences only through ratio conditionalization risks permanent certainty in propositions against which she has overwhelming evidence. To avoid this undesirable consequence, (...) I argue that we should supplement ratio conditionalization with Kolmogorov conditionalization, a strategy for updating credences based on propositions E such that P(E) = 0. Kolmogorov conditionalization can eradicate certainties, including certainties gained through prior exercises of conditionalization. Adducing general theorems and detailed examples, I show that Kolmogorov conditionalization helps us model epistemic defeat across a wide range of circumstances. (shrink)

Epistemic trustworthiness depends not only on one’s epistemic but also on moral qualities. Such qualities need to be upheld by scientific communities and institutions as well as by individual scientific experts. While non-experts can often take scientific experts’ epistemic trustworthiness for granted, in some cases they cannot rationally treat it as the default, and they need to be convinced of the experts’ commitment to the well-being of others. This study contributes to philosophical discussions on public trust in science by introducing (...) an impact assessment model. The model helps philosophers understand how scientific experts can build and maintain epistemic trustworthiness in relation to those social groups who have reasons to distrust scientists. (shrink)

Dualism holds that experiences are non-physical states that exist alongside physical states. Dualism leads to the postulation of psychophysical laws that generate experiences by operating on certain sorts of physical states. What sorts of physical states? To the limited extent that dualists have addressed this question, they have tended to favor a brain-based approach that locates the physical basis of experience in the head. In contrast, this paper develops an argument for a form of dualism on which experience has a (...) physical basis that reaches out into the world. Specifically, the argument uses a puzzle about spatial experience to support a theory I call _tracking dualism_. On tracking dualism, a psychophysical law generates experiences by operating on complex physical states that involve both brain states and tracking relations that they bear to features of the environment. To develop the argument, I discuss tracking dualism alongside its more familiar physicalist counterpart, the tracking intentionalist theory associated with Dretske, Lycan, and Tye. I conclude by outlining a tracking dualist research agenda. (shrink)

In this essay, I seek to clarify and defend a unified account of realism, i.e. a conception of realism that does not only apply to philosophy of science, but also acknowledges how realism is understood in other philosophical disciplines—particularly, how moral realism is treated in metaethics. I will argue that integrating scientific and moral realism is less straightforward than is commonly assumed, due to several substantial, but often unnoticed disanalogies that obtain between both views. As a consequence, scientific realists should (...) consider modifying their traditional understanding and move towards an alternative conception of realism—one that is much more in line with the conception that moral realists usually adopt. Realism (about science or ethics) is, in the final analysis, best characterised as an alethic view which restricts itself to an idea about the objectivity of truth, rather than an epistemic view which underwrites more extensive theses concerning the accessibility of this truth for human knowledge.

Benardete paradoxes involve a beginningless set each member of which satisfies some predicate just in case no earlier member satisfies it. Such paradoxes have been wielded on behalf of arguments for the impossibility of an infinite past. These arguments often deploy patchwork principles in support of their key linking premise. Here I argue that patchwork principles fail to justify this key premise.

The prospect of consciousness in artificial systems is closely tied to the viability of functionalism about consciousness. Even if consciousness arises from the abstract functional relationships between the parts of a system, it does not follow that any digital system that implements the right functional organization would be conscious. Functionalism requires constraints on what it takes to properly implement an organization. Existing proposals for constraints on implementation relate to the integrity of the parts and states of the realizers of roles (...) in a functional organization. This paper presents and motivates three novel integrity constraints on proper implementation not satisfied by current neural network models. It is proposed that for a system to be conscious, there must be a straightforward relationship between the material entities that compose the system and the realizers of functional roles, that the realizers of the functional roles must play their roles due to internal causal powers, and that they must continue to exist over time.

From a purely formalist viewpoint on the philosophy of mathematics, experiments cannot (and should not) play a role in warranting mathematical statements but must be confined to heuristics. Yet, due to the incorporation of new mathematical methods such as computer-assisted experimentation in mathematical practice, experiments are now conducted and used in a much broader range of epistemic practices such as concept formation, validation, and communication. In this article, we combine corpus studies and qualitative analyses to assess and categorize the epistemic (...) roles experiments are seen—by mathematicians—to have in actual mathematical practice. We do so by text-mining a corpus of reviews from the _Mathematical Reviews_, which include the indicator word “experiment”. Our qualitative, grounded classification of samples from this corpus allows us to explore the various roles played by experiments. We thus identify instances where experiments function as references to established knowledge, as tools for heuristics or exploration, as epistemic warrants, as communication or pedagogy, and instances simply proposing experiments. Focusing on the role of experiments as epistemic warrants, we show through additional sampling that in some fields of mathematics, experiments can warrant theorems as well as methods. We also show that the expressed lack of experiments by reviewers suggests concordant views that experiments could have provided epistemic warrants. Thus, our combination of corpus studies and qualitative analyses has added a typology of roles of experiments in mathematical practice and shown that experiments can and do play roles as epistemic warrants depending on the mathematical field.

Rawls’ notion of reflective equilibrium has a hybrid character. It is embedded in the pragmatist tradition, but also includes various Kantian and other non-pragmatist elements. I argue that we should discard all non-pragmatist elements and develop reflective equilibrium in a consistently pragmatist manner. I argue that this pragmatist approach is the best way to defend reflective equilibrium against various criticisms, partly by embracing the critiques as advantages. I begin with discussing how each of the three versions of reflective equilibrium in (...) Rawls’ work combines pragmatist and non-pragmatist elements. For Rawls, the primary purpose of reflective equilibrium is epistemic: namely, to construct moral theories or judgments. In a pragmatist approach, there are three connected purposes for moral inquiry: right action, reliable understanding and self-improvement. Depending on the specific context of a reflective equilibrium process, these general purposes can give rise to a variety of specific purposes. In the next sections, I develop a pragmatist approach to reflective equilibrium and discuss the implications of this approach for core elements of reflective equilibrium. These elements are: the initial convictions, facts, personal commitments and comprehensive views of life, coherence and additional methods for critical scrutiny. (shrink)

In recent years, philosophers have identified a number of moral and psychological harms associated with the attention economy (Alysworth & Castro, 2021; Castro & Pham, 2020; Williams, 2018). Missing from many of these accounts of the attention economy, however, is what exactly attention is. As a result of this neglect of the cognitive science of attention, many of these accounts are not empirically credible. They rely on oversimplified and unsophisticated accounts of not only attention, but self- control, and addiction as (...) well. Of note are accounts of the attention economy that rely on the ‘brain disease’ rhetoric of addiction and subsequent control failures (Aylsworth & Castro, 2021; Bhargava & Velasquez, 2021), accounts that rely on a strict dichotomy of top-down vs. bottom-up attention (Williams, 2018; Aylsworth & Castro, 2021), and accounts that construe attention as a limited resource (Williams, 2018). -/- Drawing on recent work from the neuroscience and psychology of attention, I demonstrate the shortcomings of these accounts and sketch a way forward for an empirically grounded account of the attention economy. These accounts tend to uphold strict dichotomies of voluntary control (e.g., compulsion versus choice, dual-process models of self-control, and top-down versus bottom-up) that cannot account for the complexities of attentional control, mental agency, and decision-making. As such, these empirically and conceptually impoverished accounts cannot adequately address the current so-called crisis of attention. To better understand the harms associated with the attention economy, we need an empirically responsible account of the nature and function of attention and mental agency. (shrink)

In this paper we articulate a characterization of the concept of disease as a social problem. We argue that, from a social ontology point of view, diseases are problems that are identified and addressed within the framework of concrete social institutions and practices (those that shape medicine). This approach allows us to overcome the classical distinction between naturalist and normativist approaches in the philosophy of medicine, taking into account both the material and the symbolic factors that shape the categories and (...) determine the practices of medicine.

Our paper contributes to the rapidly expanding body of experimental research on transformative decision making, and in the process, marks out a novel empirical interpretation for assessments of subjective value in transformative contexts. We start with a discussion of the role of subjective value in transformative decisions, and then critique extant experimental work that explores this role, with special attention to Reuter and Messerli (2018). We argue that current empirical treatments miss a crucial feature of practical deliberation manifesting across a (...) variety of everyday decisions: often, people attach more weight to decision criteria that they can know—a phenomenon known as the “evaluability bias.” In transformative contexts, if people cannot know the subjective value of an option, they are unlikely to attach it much weight. Despite this, people may care very much about such value. We then use this point to develop and present new empirical results that, in addition to supporting our concerns about evaluability bias, support the hypothesis that people care about subjective value. Our work enriches the current philosophical understanding of transformative decisions and helps to frame the emerging experimental paradigm for the empirical dimensions of the debate. (shrink)

A key ingredient of the metaphysical doctrine of dual-aspect monism is a psychophysically neutral domain, of which mental and physical aspects arise as epistemic descendants that manifest themselves by decomposition. This primer first introduces some elementary notions to define the basic concepts needed to understand the approach, such as those of states, state spaces, observables, partitions and correlations. Using these notions, the concepts of decomposition and manifestation are explained, and a differentiated view of the mereological distinction of wholes and parts (...) is outlined. Next, a number of historical and contemporary accounts of psychophysical neutrality with philosophical (Plato, Spinoza, Schelling, Kant), scientific (Bohm, Pauli, Jung, Connes, Gibson), and artistic (sculpture, music) flavor are given as illustrative examples. Finally, correlations between the psychophysically neutral, the mental, and the physical domain of reality are discussed, in which these correlations are substantiated by meaning. (shrink)

Our ordinary conception of time has it that there are temporal particulars: not only do people do things, but there are particular doings by people; not only are we born, but the birth of each one of us was a particular event, and each of us will have our own particular death. Temporal particulars in this sense are individuated, fundamentally, by their temporal locations or relations, rather than by their intrinsic or qualitative characteristics. In this respect they are unrepeatable, not (...) just de facto, but as a matter of their very nature. However, there is a tradition in philosophy that seriously downplays this aspect of our thinking about time. According to this tradition, the fundamental unit of temporal representation is _tensed truth_; the notion of an unrepeatable particular, individuated by its temporal location, is at best an abstraction from a complex of tensed truths. The aims of this paper are, first, to argue that the representation of temporal particulars is deeply implicated in our ordinary conception of the past as fixed and unalterable; and, secondly, to argue that the theorist of tensed truth is able to provide only a pale imitation of this aspect of our thinking. I will then reflect on the consequences of this for debates about the metaphysics of tense. (shrink)

A formal theory of causal reasoning is presented that encompasses both Pearl’s approach to causality and several key formalisms of nonmonotonic reasoning in Artificial Intelligence. This theory will be derived from a single rationality principle of causal acceptance for propositions. However, this principle will also set the theory of causal reasoning apart from common representational approaches to reasoning formalisms.

This paper ties together three threads of discussion about the following question: in accepting a system of axioms S, what else are we thereby warranted in accepting, on the basis of accepting S? First, certain foundational positions in the philosophy of mathematics are said to be epistemically stable, in that there exists a coherent rationale for accepting a corresponding system of axioms of arithmetic, which does not entail or otherwise rationally oblige the foundationalist to accept statements beyond the logical consequences (...) of those axioms. Second, epistemic stability is said to be incompatible with the implicit commitment thesis, according to which accepting a system of axioms implicitly commits the foundationalist to accept additional statements not immediately available in that theory. Third, epistemic stability stands in tension with the idea that in accepting a system of axioms S, one thereby also accepts soundness principles for S. We offer a framework for analysis of sets of implicit commitment which reconciles epistemic stability with the latter two notions, and argue that all three ideas are in fact compatible. (shrink)

The traditional conception of immune function is that of a system which differentiates the organism’s own tissues (the self) from any foreign invaders (nonself), preserving the former by rejecting the latter. In a mammalian pregnancy, however, the immunologically foreign foetus is accepted by the gestator’s immune system. This presents a serious challenge to the self–nonself theory which has sometimes been called the immunological paradox of pregnancy. In this paper I shall defend the self–nonself theory against the critique posed by Thomas (...) Pradeu. In addition I critically examine the alternative he proposes—the continuity theory. The main problem I will raise for any theory of immunology is that the phenomenon to be explained in pregnancy is the non-rejection of the foetus despite the triggering of the gestator’s immune system. I will argue that contemporary modified versions of the self–nonself theory can rise to this challenge but that continuity theory cannot. As such, the immunology of pregnancy gives us a good reason to favour contemporary self–nonself theory over the continuity theory. (shrink)

Given the extent of using deep convolutional neural networks to model the mechanism of object recognition, it becomes important to analyse the evidence of their similarity and the explanatory potential of these models. I focus on one frequent method of their comparison—representational similarity analysis, and I argue, first, that it underdetermines these models as how-actually mechanistic explanations. This happens because different similarity measures in this framework pick out different mechanisms across DCNNs and the brain in order to correspond them, and (...) there is no arbitration between them in terms of relevance for object recognition. Second, the reason similarity measures are underdetermining to a large degree stems from the highly idealised nature of these models, which undermines their status as how-possibly mechanistic explanatory models of object recognition as well. Thus, building models with more theoretical consideration and choosing relevant similarity measures may bring us closer to the goal of mechanistic explanation. (shrink)

According to an influential account of the new mechanistic philosophy of science, entities and activities compose mechanisms. However, the new mechanists have paid too little attention to activities. Critics have charged that accounts of activities in the new mechanism literature are philosophically uninformative and opaque. This paper defends a novel account of causally productive activities, which I call the Hybrid Account, that marries the two dominant philosophical approaches to causation: production and difference-making. The Hybrid Account of Activities (HAA) identifies causally (...) productive activities as robust difference-makers to the next stage of a mechanism. The Hybrid Account provides attractive solutions to causal identification and causal selection problems faced by earlier activities views. (shrink)

In Posterior Analytics 1.13, Aristotle introduced a distinction between two kinds of demonstrations: of the fact (quia), and of the reasoned fact (propter quid). Both demonstrations take a syllogistic form, in which the middle term links either two facts (in the case of quia demonstrations) or a proximate cause and a fact (in the case of propter quid demonstrations). While Aristotle stated that all the terms of one demonstration must be taken from within the same subject matter, he admitted some (...) exceptions in which the fact and the reasoned fact are instantiated by terms from different sciences, as when mathematics provides the reason and another science the empirical fact. This was the methodological foundation of the “mixed sciences”, a subject of varying interpretations in the thirteenth century. Roger Bacon (C. 1220–1292), adhering to Robert Grosseteste’s (C. 1168–1563) commentary on Posterior Analytics, presented a unique interpretation of this exception. He replaced propositional demonstrations with geometrical considerations and diagrams, thus producing geometrical arguments for theorems in natural philosophy. I focus on Bacon’s propter quid arguments, as applied in three case studies: (1) the heat caused by a body moving to its natural place; (2) the motion of the scale; (3) and the contraction of water. Based on an analysis of these demonstrations, I argue that Bacon’s interpretation of propter quid demonstration reflects his application of a scientific methodology that imbues geometrical objects with causal power over material bodies.

I argue that a certain kind of naturalist approach to social ontology is likely to be both philosophically fruitful and relevant to empirical social science. The kind of naturalism I employ might be called contextualism, which emphasizes the constant presence of assumed background knowledge, is suspicious of general inference rules and all or nothing claims about the ontology of the social sciences, and argues that Quine’s quantificational criterion for ontological commitment has to be supplemented with local interpretations and arguments about (...) what specific social science research is committed to. I look at three case studies employing this perspective, one on agent based models and individualism, a second on the reality of social class, and a third on the reality of race. In all three cases work is first needed to clarifying what empirical social science is claiming, what ontology or ontologies it seems to presuppose, and then description of the kinds of evidence that supports its commitments.

This paper develops a way to model performative speech acts within a framework of dynamic semantics. It introduces a distinction between performative and informative updates, where informative updates filter out indices of context sets (cf. Stalnaker, Cole (ed), Pragmatics, Academic Press, 1978), whereas performative updates change their indices (cf. Szabolcsi, Kiefer (ed), Hungarian linguistics, John Benjamins, 1982). The notion of index change is investigated in detail, identifying implementations by a function or by a relation. Declarations like _the meeting is (hereby) (...) adjourned_ are purely performative updates that just enforce an index change on a context set. Assertions like _the meeting is (already) adjourned_ are analyzed as combinations of a performative update that introduces a guarantee of the speaker for the truth of the proposition, and an informative update that restricts the context set so that this proposition is true. The first update is the illocutionary act characteristic for assertions; the second is the primary perlocutionary act, and is up for negotiations with the addressee. Several other speech acts will be discussed, in particular commissives, directives, exclamatives, optatives, and definitions, which are all performative, and differ from related assertions. The paper concludes a discussion of locutionary acts, which are modelled as index changers as well, and proposes a novel analysis for the performative marker _hereby._. (shrink)

Critical psychiatry has recently echoed Szasz’s longstanding concerns about medical understandings of mental distress. According to Szaszianism, the analogy between mental and somatic disorders is illegitimate because the former presuppose psychosocial and ethical norms, whereas the latter merely involve deviations from natural ones. So-called “having-it-both-ways” views have contested that social norms and values play a role in _both_ mental and somatic healthcare, thus rejecting that the influence of socio-normative considerations in mental healthcare compromises the analogy between mental and somatic disorders. (...) This paper has two goals. Firstly, I argue that having-it-both-ways views fail to provide a compelling answer to Szasz’s challenge. The reason is that what is essential to Szasz’s argument is not that mental disorder attributions involve value judgements, but that mental attributions _in general_ do. Mental disorders are thus doubly value-laden and, _qua_ mental, only metaphorically possible. To illustrate this, I construe Szasz’s view and Fulford’s having-it-both-ways approach as endorsing two different kinds of expressivism about mental disorders, pointing out their different implications for the analysis of delusions. Secondly, I argue, against Szaszianism, that Szasz’s rejection of the analogy is relatively irrelevant for discussions about the appropriateness of medicalizing mental distress. Specifically, I draw from socio-normative approaches to the psychopathology/social deviance distinction and mad and neurodiversity literature to argue that a) it is still possible to distinguish social deviance from psychopathology once we reject the analogy; and b) that _both_ medicalizing and normalizing attitudes to mental distress can harmfully wrong people from relevant collectives.

Counterpossibles are counterfactuals with an impossible antecedent. According to the orthodox view of counterfactuals, all counterpossibles are vacuously true. This is puzzling because some counterpossible statements seem to be false. The paper analyzes two approaches to explaining why certain counterpossibles, though perhaps true, may appear to be false. The first, which appeals to the Gricean mechanism of conversational implicatures, asserts that some counterpossibles appear to be false because their assertion carries with it a false conversational implicature. However, I argue that, (...) under a closer scrutiny, this approach collapses. I therefore turn to a second approach, proposed by Timothy Williamson. It appeals to a heuristic according to which speakers may regard a counterpossible to be false if they have previously accepted its opposite. Since the applicability of Williamson’s solution is limited, I suggest a more general account. Its underlining idea is that a counterpossible is rejected if the speaker cannot find what they regard as a universally true conditional function derivable from the counterpossible by substitutions and syntactic transformations.

This article investigates the connection and dependence between the definiteness of the totalities involved in mathematical structures and the determinateness of statements about that structure. From a logical perspective, we investigate whether logical principles expressing the definiteness of totalities license the use of classical logic. From a philosophical perspective, this article provides a reconstruction of Solomon Feferman’s claim that the definiteness of the natural number conception implies the determinateness of arithmetical statements and therefore justifies the adoption of classical logic for (...) arithmetical theories.

Contra recent, inflationary views, the paper submits a deflationary approach to legal ontology. It argues, in particular, that to answer ontological questions about legal entities, we only need conceptual analysis and empirical investigation. In developing this proposal, it follows Amie Thomasson’s ‘easy ontology’ and her strategy for answering whether ordinary objects exist. The purpose of this is to advance a theory that, on the one hand, does not fall prey to sceptical views about legal reality (viz., that ontological truths about (...) legal entities are established by metaphysical principles); and, on the other, is compatible with common-sense jurisprudence (viz., that there in fact exist legal entities, and they all have important practical implications). While this methodology is common to legal philosophers interested in elucidating the ‘artifactual nature’ of law, the paper departs from their projects by taking a step forward in connecting this deflationary approach to legal ontology with an expressivist account of legal discourse, thus providing enough resources to satisfy the general ambition of jurisprudence, viz., to establish the conditions for the analysis of legal reality and its normative character.

There is an ongoing debate on the ontology of relations, which features four main competing approaches: directionalism, positionalism, anti-positionalism, and primitivism. This paper focuses on a particular version of positionalism, namely role positionalism, and proposes the results of an experimental philosophy research concerning aspects of it. We tested the intuitions of ordinary subjects regarding the inter-relational generality of the roles typically assumed for spatial and kinematic relations, namely source, destination, theme, location. According to a 2014 paper by Orilia, this generality (...) is rather wide, as it encompasses relations of temporal order, causation, quantitative order, transaction, possession, and parthood. Our findings do not support this proposal, except for parthood, and, in a limited way, for temporal order. We also tested the intuitions of ordinary subjects regarding the contrast between the pro-converses option, according to which non-symmetric relations split into distinct converse relations, and the anti-converses option, according to which non-symmetric relations have no distinct converses. Although traditionally positionalism is associated to the latter option, in recent works by Orilia role positionalism is associated to the former option for at least some relations, while remaining anchored to the latter option for other relations. Our findings support this mixed line to some extent, but not quite in the way suggested by Orilia in such works. (shrink)

A hyperintensional epistemic logic would take the contents which can be known or believed as more fine-grained than sets of possible worlds. I consider one objection to the idea: Williamson’s Objection from Overfitting. I propose a hyperintensional account of propositions as sets of worlds enriched with topics: what those propositions, and so the attitudes having them as contents, are about. I show that the account captures the conditions under which sentences express the same content; that it can be pervasively applied (...) in formal and mainstream epistemology; and that it is left unscathed by the objection.

In this paper, I aim to discuss what puns, metaphysically, are. I argue that the type-token view of words leads to an indeterminacy problem when we consider puns. I then outline an alternative account of puns, based on recent nominalist views of words, that does not suffer from this indeterminacy.

A common objection to Sosa’s epistemology is that it countenances, in an objectionable way, unsafe knowledge. This objection, under closer inspection, turns out to be in far worse shape than Sosa’s critics have realised. Sosa and his defenders have offered two central response types to the idea that allowing unsafe knowledge is problematic: one response type adverts to the animal/reflective knowledge distinction that is characteristic of bi-level virtue epistemology. The other less-discussed response type appeals to the threat of dream scepticism, (...) and in particular, to the idea that many of our everyday perceptual beliefs are unsafe through the nearness of the dream possibility. The latter dreaming response to the safety objection to Sosa’s virtue epistemology has largely flown under the radar in contemporary discussions of safety and knowledge. We think that, suitably articulated in view of research in the philosophy and science of dreaming, it has much more going for it than has been appreciated. This paper further develops, beyond what Sosa does himself, the dreaming argument in response to those who think safety (as traditionally understood) is a condition on knowledge and who object to Sosa’s account on the grounds that it fails this condition. The payoffs of further developing this argument will be not only a better understanding of the importance of insights about dreaming against safety as a condition on knowledge, but also some reason to think a weaker safety condition, one that is relativised to SSS (i.e., skill/shape/situation) conditions for competence exercise, gets better results all things considered as an anti-luck codicil on knowledge.

Physicist Percy Bridgman has been taken by Heather Douglas to be an exemplar defender of an untenable value-free ideal for science. This picture is complicated by a detailed study of Bridgman's philosophical views of the relation between science and society. The normative autonomy of science, a version of the value-free ideal, is defended. This restriction on the provenance of permissible values in science is given a basis in Bridgman's broader philosophical commitments, most importantly, his view that science is primarily an (...) individual commitment to a set of epistemic norms and values. Considerations of external moral or social values are not, on this view, intrinsic to scientific practice, though they have a broader pragmatic significance. What Bridgman takes as the proper relation between science and society is shown through analysis of his many writings on the topic and consideration of his rarely remarked upon involvement in the most problematic example of "Big Science" of his day: the atomic bomb. A reevaluation of Bridgman's views provides a unique characterization of what is at stake in the values in science debate: the normative autonomy of science. (shrink)
