Conditional constructions (if–then) enable us to express our thoughts about possible states of the world, and they form an important ingredient for our reasoning and argumentative capabilities. Different types and argumentative uses have been distinguished in the literature, but their applicability to actual language use is rarely evaluated. This paper focuses on the reliability of applying classifications of connections between antecedents and consequents of conditionals to discourse, and three issues are identified. First, different accounts produce incompatible results when applied to (...) language data. Second, a discrepancy between theory and data was observed in previous studies, which sometimes discard existing classifications for being detached from actual language use. Finally, language users construct various cognitive relations between clauses of conditionals without being able to rely on overt linguistic features, which poses problems for the annotation of conditionals in argumentation and discourse. This paper addresses these issues by means of comparing theoretical types and actual uses of conditionals, by inspecting the dispersion of types in natural-language corpora, and by conducting an experiment in which the inter-rater reliability of classifications was assessed. The results show that the reliability of classifications of conditionals when applied to language data is low. With respect to the aforementioned issues, different classifications produced incompatible results, a discrepancy between theory and data was indeed observed, and low reliability scores indicated a largely interpretative nature of types of conditionals. Given these results, suggestions for the enhancement of reliability in corpus studies of conditionals and beyond are provided to enhance future classification design. (shrink)

Although decision‐making algorithms are not new to medicine, the availability of vast stores of medical data, gains in computing power, and breakthroughs in machine learning are accelerating the pace of their development, expanding the range of questions they can address, and increasing their predictive power. In many cases, however, the most powerful machine learning techniques purchase diagnostic or predictive accuracy at the expense of our ability to access “the knowledge within the machine.” Without an explanation in terms of reasons or (...) a rationale for particular decisions in individual cases, some commentators regard ceding medical decision‐making to black box systems as contravening the profound moral responsibilities of clinicians. I argue, however, that opaque decisions are more common in medicine than critics realize. Moreover, as Aristotle noted over two millennia ago, when our knowledge of causal systems is incomplete and precarious—as it often is in medicine—the ability to explain how results are produced can be less important than the ability to produce such results and empirically verify their accuracy.

In this paper, I defend the view that it is wrong for us to consume only, or overwhelmingly, media that broadly aligns with our own political viewpoints: that is, it is wrong to be politically “partisan” in our decisions about what media to consume. We are obligated to consume media that aligns with political viewpoints other than our own – to “diversify our sources”. This is so even if our own views are, as a matter of fact, substantively correct.

Philosophy of Medicine provides a fresh and comprehensive treatment of the topic. It offers a novel theory of the nature of medicine, and proposes a new attitude to medicine, aimed at improving the quality of debates between medical traditions and facilitating medicine's decolonization.

What is it to want something? Or, as philosophers might ask, what is a desire? This book defends “desire-as-belief”, the view that desires are just a special subset of our beliefs: normative beliefs. This view entitles us to accept orthodox models of human motivation and rationality that explain those things with reference to desire, but nonetheless to also make room for our normative beliefs to play a role in those domains. And this view tells us to diverge from the orthodox (...) view on which desires themselves can never be right or wrong. Rather, according to desire-as-belief, our desires can themselves be assessed for their accuracy, and they are wrong when they misrepresent normative features of the world. Hume says that it is not contrary to reason to prefer the destruction of the whole world to the scratching of your finger, but he is wrong: it is foolish to prefer the destruction of the whole world to the scratching of your finger, and this is foolish because this preference misrepresents the relative worth of these things.

In her black and white room, Mary doesn’t know what it is like to see red. Only after undergoing an experience as of something red and hence acquainting herself with red can Mary learn what it is like. But learning what it is like to see red requires more than simply becoming acquainted with it. To be acquainted with something is to know it, but such knowledge, as we argue, is object-knowledge rather than propositional-knowledge. To know what it is like (...) one must know an appropriate propositional answer to the question ‘what is it like?’. Despite this mismatch between object-knowledge and knowing an answer, we believe that acquaintance is crucial to Mary’s epistemic progress. When Mary leaves her black and white room, her new knowledge tempts one to think that she must come to know a candidate answer (a coarse-grained fact) that she didn’t know in her room. Since Mary already knows all the physical facts in her room, any additional facts she might learn appear to threaten physicalism. In reply, many physicalists have been attracted to the phenomenal concept strategy according to which Mary can come to have new knowledge and hence know a new answer to the question ‘what is it like to see red?’ by entertaining a coarse-grained fact under a concept she didn’t possess in her room – Mary learns a new fine-grained fact. We believe both of these accounts of Mary’s epistemic progress are mistaken. As we argue, Mary could know every fact (coarse-grained and fine-grained) that might serve as an answer to the question ‘what is it like to see red?’ and still not know what it is like. The physical world leaves no leftover coarse-grained facts for Mary to learn and because concepts are sharable, easy to possess, and easy to introduce, there are possible situations in which Mary, while in her black and white room, has every concept that might make a fine-grained difference. In short, even when Mary is granted a great deal of factual knowledge and vast conceptual resources, she may still not know an appropriate answer to the question ‘what is it like to see red?’. But in any such situation, Mary lacks acquaintance with red and on this basis we argue that in order to know what it is like, in order for Mary to know an appropriate answer, Mary’s propositional knowledge must be appropriately related to her acquaintance with red.

In this paper, we consider how certain longstanding philosophical questions about mental representation may be answered on the assumption that cognitive and perceptual systems implement hierarchical generative models, such as those discussed within the prediction error minimization framework. We build on existing treatments of representation via structural resemblance, such as those in Gładziejewski :559–582, 2016) and Gładziejewski and Miłkowski, to argue for a representationalist interpretation of the PEM framework. We further motivate the proposed approach to content by arguing that it (...) is consistent with approaches implicit in theories of unsupervised learning in neural networks. In the course of this discussion, we argue that the structural representation proposal, properly understood, has more in common with functional-role than with causal/informational or teleosemantic theories. In the remainder of the paper, we describe the PEM framework for approximate Bayesian inference in some detail, and discuss how structural representations might arise within the proposed Bayesian hierarchies. After explicating the notion of variational inference, we define a subjectively accessible measure of misrepresentation for hierarchical Bayesian networks by appeal to the Kullbach–Leibler divergence between posterior generative and approximate recognition densities, and discuss a related measure of objective misrepresentation in terms of correspondence with the facts.

I begin the paper by outlining one classic argument for the guise of the good: that we must think that desires represent their objects favourably in order to explain why they can make actions rational (Quinn 1995; Stampe 1987). But what exactly is the conclusion of this argument? Many have recently formulated the guise of the good as the view that desires are akin to perceptual appearances of the good (Oddie 2005; Stampe 1987; Tenenbaum 2007). But I argue that this (...) view fails to capitalize on the above argument, and that the argument is better understood as favouring a view on which desires are belief-like states. I finish by addressing some countervailing claims made by Avery Archer (2016). (shrink)

In a narrow sense of ‘disagreement,’ you and I disagree iff we believe inconsistent propositions. But there are numerous cases not covered by this definition that seem to constitute disagreements in a wider sense: disagreements about what to do, disagreements in attitude, disagreements in credence, etc. This wider sense of disagreement plays an important role in metaethics and epistemology. But what is it to disagree in the wider sense? On the view I’ll defend, roughly, you and I disagree in the (...) wide sense iff we hold attitudes that it would be incoherent for a single individual to hold. I’ll argue that this captures the relevant cases, and explore the consequences for metaethical debates between expressivists and contextualists. My view has two broader upshots: that coherence is a theoretically important property, and that an apparently descriptive question—are two subjects disagreeing?—turns on a normative one—are their attitudes jointly incoherent?

This paper investigates how inquiry into normative language can improve substantive normative theorizing. First I examine two dimensions along which normative language differs: “strength” and “subjectivity.” Next I show how greater sensitivity to these features of the meaning and use of normative language can illuminate debates about three issues in ethics: the coherence of moral dilemmas, the possibility of supererogatory acts, and the connection between making a normative judgment and being motivated to act accordingly. The paper concludes with several brief (...) reflections on the theoretical utility of the distinction—at least so-called—between “normative” and “non-normative” language and judgment. Clarifying the language we use in normative conversation and theorizing can help us diagnose problems with bad arguments and formulate better motivated questions. This can lead to clearer answers and bring into relief new theoretical possibilities and avenues to explore. (shrink)

The history of the idea of predicate is the history of its emancipation. The lesson of this paper is that there are two more steps to take. The first is to recognize that predicates need not have a fixed degree, the second that they can combine with plural terms. We begin by articulating the notion of a multigrade predicate: one that takes variably many arguments. We counter objections to the very idea posed by Peirce, Dummett's Frege, and Strawson. We show (...) that the arguments of a multigrade predicate must be grouped into places, with perhaps several arguments occupying positions at a place. Variability may relate to places or positions. Russell's multiple judgement predicate turns out to be just one example of a family-'is necessarily true of', 'is said of', 'is instantiated by' and so on-of predicates with variably many places. Our main concern, however, is lists. Any adequate account of lists must include plural as well as singular terms. On one account, lists are mere strings of separate arguments, which occupy variably many positions within a place of a multigrade predicate. A quite different account takes the list itself to be a compound plural term. We compare these rival conceptions, and reach some surprising conclusions. As a coda, we deploy the conceptual apparatus developed in the paper to assess Morton's pioneer system of multigrade logic. (shrink)

Russell had two theories of definite descriptions: one for singular descriptions, another for plural descriptions. We chart its development, in which ‘On Denoting’ plays a part but not the part one might expect, before explaining why it eventually fails. We go on to consider many-valued functions, since they too bring in plural terms—terms such as ‘4’ or the descriptive ‘the inhabitants of London’ which, like plain plural descriptions, stand for more than one thing. Logicians need to take plural reference seriously (...) if only because mathematicians take many-valued functions seriously. We assess the objection (by Russell, Frege and others) that many-valued functions are illegitimate because the corresponding terms are ambiguous. We also assess the various methods proposed for getting rid of them. Finding the objection ill-founded and the methods ineffective, we introduce a logical framework that admits plural reference, and use it to answer some earlier questions and to raise some more.

We all learn about the mistake of treating ‘nothing’ as if it were a term standing for something; but is it a mistake to treat it as an empty term, denoting nothing? We argue not, and we introduce ‘zilch’, defined as ‘the non-self-identical thing’, as a term which is empty as a matter of logical necessity. We contrast its behaviour with that of the quantifier ‘nothing’, and illustrate its uses. We use the same idea to vindicate Locke’s, Descartes’ and Hume’s (...) handling of ‘nothing’, and we show how Heidegger’s ‘das Nichts nichtet’ comes out as logically true. (shrink)

We present a plural logic that is as expressively strong as it can be without sacrificing axiomatisability, axiomatise it, and use it to chart the expressive limits set by axiomatisability. To the standard apparatus of quantification using singular variables our object-language adds plural variables, a predicate expressing inclusion (is/are/is one of/are among), and a plural definite description operator. Axiomatisability demands that plural variables only occur free, but they have a surprisingly important role. Plural description is not eliminable in favour of (...) quantification; on the contrary, quantification is definable in terms of it. Predicates and functors (function signs) can take plural as well as singular terms as arguments, and both many-valued and single-valued functions are expressible. The system accommodates collective as well as distributive predicates, and the condition for a predicate to be distributive is definable within it; similarly for functors. An essential part of the project is to demonstrate the soundness and completeness of the calculus with respect to a semantics that does without set-theoretic domains and in which the use of settheoretic extensions of predicates and functors is replaced by the sui generis relations and functions for which the extensions were at best artificial surrogates. Our metalanguage is designed to solve the difficulties involved in talking plurally about individuals and about the semantic values of plural items. (shrink)

Research suggests that interventions involving extensive training or counterconditioning can reduce implicit prejudice and stereotyping, and even susceptibility to stereotype threat. This research is widely cited as providing an “existence proof” that certain entrenched social attitudes are capable of change, but is summarily dismissed—by philosophers, psychologists, and activists alike—as lacking direct, practical import for the broader struggle against prejudice, discrimination, and inequality. Criticisms of these “debiasing” procedures fall into three categories: concerns about empirical efficacy, about practical feasibility, and about the (...) failure to appreciate the underlying structural-institutional nature of discrimination. I reply to these criticisms of debiasing, and argue that a comprehensive strategy for combating prejudice and discrimination should include a central role for training our biases away. (shrink)

Response-dependence theories have historically been very popular in aesthetics, and aesthetic response-dependence has motivated response-dependence in ethics. This chapter closely examines the prospects for such theories. It breaks this category down into dispositional and fittingness strands of response-dependence, corresponding to descriptive and normative ideal observer theories. It argues that the latter have advantages over the former but are not themselves without issue. Special attention is paid to the relationship between hedonism and response-dependence. The chapter also introduces two aesthetic properties that (...) lead to wrong kinds of reasons problems for aesthetic response-dependence: insightfulness and the capacity to change one’s perspective. These properties do not have obvious parallels in the ethical domain, and so present an obstacle for response-dependence even in aesthetics. The chapter ends by examining replies on behalf of the response-dependence theorist, ultimately suggesting that a restricted form of response-dependence is the most promising way forward for fans of such theories.

This book explores how our minds represent things in the world, asking whether these representations necessarily have the structure of propositions about the world. The hope is that this will lead towards a more complete understanding of the puzzle of intentionality -- how it is that our minds make contact with the world.

A short reply to Sankey's 'To Believe is to Believe True'.

In this paper, I argue that theories of perception that appeal to Helmholtz’s idea of unconscious inference (“Helmholtzian” theories) should be taken literally, i.e. that the inferences appealed to in such theories are inferences in the full sense of the term, as employed elsewhere in philosophy and in ordinary discourse. -/- In the course of the argument, I consider constraints on inference based on the idea that inference is a deliberate acton, and on the idea that inferences depend on the (...) syntactic structure of representations. I argue that inference is a personal-level but sometimes unconscious process that cannot in general be distinguished from association on the basis of the structures of the representations over which it’s defined. I also critique arguments against representationalist interpretations of Helmholtzian theories, and argue against the view that perceptual inference is encapsulated in a module. (shrink)

We situate the debate on intentionality within the rise of cognitive neuroscience and argue that cognitive neuroscience can explain intentionality. We discuss the explanatory significance of ascribing intentionality to representations. At first, we focus on views that attempt to render such ascriptions naturalistic by construing them in a deflationary or merely pragmatic way. We then contrast these views with staunchly realist views that attempt to naturalize intentionality by developing theories of content for representations in terms of information and biological function. (...) We echo several other philosophers by arguing that these theories over-generalize unless they are constrained by a theory of the functional role of representational vehicles. This leads to a discussion of the functional roles of representations, and how representations might be realized in the brain. We argue that there’s work to be done to identify a distinctively mental kind of representation. We close by sketching a way forward for the project of naturalizing intentionality. This will not be achieved simply by ascribing the content of mental states to generic neural representations, but by identifying specific neural representations that explain the puzzling intentional properties of mental states.

Discussions of aesthetic reasons and normativity are becoming increasingly popular. This piece outlines six basic questions about aesthetic reasons, normativity, and value and discusses the space of possible answers to these questions. I divide the terrain into two groups of three questions each. First are questions about the shape of aesthetic reasons: what they favour, how strong they are, and where they come from. Second are relational questions about how aesthetic reasons fit into the wider normative landscape: whether they are (...) distinctive, what their normative status is, and how they interact with each other and with non-aesthetic reasons. This piece aims to provide a taxonomy to clarify and organise the burgeoning literature and to make a few concrete suggestions for avenues of future research. (shrink)

In order for the so-called strengthened impairment argument to succeed, it must posit some reason R that causing fetal alcohol syndrome is immoral, one that also holds in cases of abortion. In formulating SIA, Blackshaw and Hendricks borrow from Don Marquis to claim that the reason R that causing FAS is immoral lies in the fact that it deprives an organism of a future like ours. I argue here that SIA fails to show that it is immoral to cause FAS (...) and abort fetuses that will not be born because it deprives them of an FLO. This is because fetuses that will not be born have no chance of having an FLO in the first place, so causing FAS for and aborting them cannot deprive them of one. I then consider three responses to my argument. I conclude that each fails. SIA does not accomplish its task of showing why it is immoral to impair fetuses that will not be born. Perhaps it can accomplish the task of showing why it is immoral to impair fetuses that will be born, but not without sacrificing at least some of its alleged significance. (shrink)

Positive logics are $\{ \wedge, \vee, \to \}$-fragments of intermediate logics. It is clear that the positive fragment of $Int$ is not structurally complete. We give a description of all hereditarily structurally complete positive logics, while the question whether there is a structurally complete positive logic which is not hereditarily structurally complete, remains open.

I provide an opinionated overview of the literature on the relationship of contextualism to knowledge norms for action, assertion, and belief. I point out that contextualists about ‘knows’ are precluded from accepting the simplest versions of knowledge norms; they must, if they are to accept knowledge norms at all, accept “relativized” versions of them. I survey arguments from knowledge norms both for and against contextualism, tentatively concluding that commitment to knowledge norms does not conclusively win the day either for contextualism (...) or for its rivals. But I also suggest that an antecedent commitment to contextualism about normative terms may provide grounds for suspicion about knowledge norms, and a debunking explanation of some of the data offered in favor of such norms.

This paper tries to do three things. First, it tries to make it plausible that correct rules of reasoning do not always preserve justification: in other words, if you begin with a justified attitude, and reason correctly from that premise, it can nevertheless happen that you’ll nevertheless arrive at an unjustified attitude. Attempts to show that such cases in fact involve following an incorrect rule of reasoning cannot be vindicated. Second, it also argues that correct rules of reasoning do not (...) even correspond to permissions of “structural rationality”: it is not always structurally permissible to base an attitude on other attitudes from which it follows by correct reasoning. Third, from these observations it tries to build a somewhat positive account of the correctness of rules of reasoning as a more sui generis notion irreducible to either justification or structural rationality. This account vindicates an important unity of theoretical and practical reasoning as well as a qualified version of the thesis that deductive logic supplies correct rules of reasoning. (shrink)

The most influential philosopher in the analytic tradition of his time, Willard Van Orman Quine changed the way we think about language and its relation to the world. His rejection of the analytic/synthetic distinction, his scepticism about modal logic and essentialism, his celebrated theme of the indeterminacy of translation, and his advocacy of naturalism have challenged key assumptions of the prevailing orthodoxy and helped shape the development of much of recent philosophy. This introduction to Quine's philosophical ideas provides philosophers, students (...) and generalists with an authoritative analysis of his lasting contributions to philosophy. Quine's ideas throughout are contrasted with more traditional views, as well as with contemporaries such as Frege, Russell, Carnap, Davidson, Field, Kripke and Chomsky, enabling the reader to grasp a clear sense of the place of Quine's views in twentieth-century philosophy and the important criticisms of them.

It seems possible to see a star that no longer exists. Yet it also seems right to say that what no longer exists cannot be seen. We therefore face a puzzle, the traditional answer to which involves abandoning naïve realism in favour of a sense datum view. In this article, however, I offer a novel exploration of the puzzle within a naïve realist framework. As will emerge, the best option for naïve realists is to embrace an eternalist view of time, (...) and claim that in the relevant case, one sees a still existent star‐stage located somewhere in the distant past.

Adverbialist theories of thought such as those advanced by Hare and Sellars promise an ontologically sleek understanding of a variety of intentional states, but such theories have been largely abandoned due to the ‘many-property problem’. In an attempt to revitalize this otherwise attractive theory, in a series of papers as well as his recent book, Uriah Kriegel has offered a novel reply to the ‘many-property problem’ and on its basis he argues that ‘adverbialism about intentionality is alive and well’. If (...) true, Kriegel will have shown that the logical landscape has long been unnecessarily constrained. His key idea is that the many-property problem can be overcome by appreciating that mental states stand in the determinable–determinate relation to one another. The present paper shows that this relation can’t save adverbialism because it would require thinkers to think more thoughts than they need be thinking. (shrink)

Intersubjectivity refers to the variety of possible relations between perspectives. It is indispensable for understanding human social behaviour. While theoretical work on intersubjectivity is relatively sophisticated, methodological approaches to studying intersubjectivity lag behind. Most methodologies assume that individuals are the unit of analysis. In order to research intersubjectivity, however, methodologies are needed that take relationships as the unit of analysis. The first aim of this article is to review existing methodologies for studying intersubjectivity. Four methodological approaches are reviewed: comparative self-report, (...) observing behaviour, analysing talk and ethnographic engagement. The second aim of the article is to introduce and contribute to the development of a dialogical method of analysis. The dialogical approach enables the study of intersubjectivity at different levels, as both implicit and explicit, and both within and between individuals and groups. The article concludes with suggestions for using the proposed method for researching intersubjectivity both within individuals and between individuals and groups. (shrink)

Robotic warfare has now become a real prospect. One issue that has generated heated debate concerns the development of ‘Killer Robots’. These are weapons that, once programmed, are capable of finding and engaging a target without supervision by a human operator. From a conceptual perspective, the debate on Killer Robots has been rather confused, not least because it is unclear how central elements of these weapons can be defined. Offering a precise take on the relevant conceptual issues, the article contends (...) that Killer Robots are best seen as executors of targeting decisions made by their human programmers. However, from a normative perspective, the execution of targeting decisions by Killer Robots should worry us. The article argues that what is morally bad about Killer Robots is that they replace human agency in warfare with artificial agency, a development which should be resisted. Finally, the article contends that the issue of agency points to a wider problem in just war theory, namely the role of moral rights in our normative reasoning on armed conflict. (shrink)

Are grounding claims fully general in character? If an object a is F in virtue of being G, does it follow that anything that’s G is F for that reason? According to the thesis of Weak Formality, the answer here is ‘yes’. In this paper, however, I argue that there is philosophical utility in rejecting this thesis. More exactly, I argue that two currently unresolved problems in contemporary metaphysics can be dealt with if we hold that there can be cases (...) of ‘kind-dependent grounding’, the key thought being that once we allow for such cases, we must also accept that Weak Formality is false.

Despite increasing prominence, ‘ought’-contextualism is regarded with suspicion by most metaethicists. As I’ll argue, however, contextualism is a very weak claim, that every metaethicist can sign up to. The real controversy concerns how contextualism is developed. I then draw an oft-overlooked distinction between “parochial” contextualism—on which the contextually-relevant standards are those that the speaker, or others in her environment, subscribe to—and “aspirational” contextualism—on which the contextually-relevant standards are the objective standards for the relevant domain. However, I argue that neither view (...) is acceptable. I suggest an original compromise: “ecumenical contextualism”, on which some uses of ‘ought’ are parochial, others aspirational. Ecumenical contextualism is compatible with realism or antirealism, but either combination yields interesting results. And though it’s a cognitivist view, it is strengthened by incorporating an expressivist insight: for robustly normative usages of ‘ought’, the contextually-relevant standards must be endorsed by the speaker.

Intentionalism about demonstratives is the view that the referent of a demonstrative is determined solely by the speaker's intentions. Intentionalists can disagree about the nature of these intentions, but are united in rejecting the relevance of other factors, such as the speaker's gestures, her gaze, and any facts about the addressee or the audience. In this paper, I formulate a particular version of this view, and I defend it against six objections, old and new.

In "Frege: Philosophy of Mathematics" Dummett recommends the following thesis, (PNP): the correct analysis of any sentence containing a plural noun phrase will show that the phrase is functioning predictively. According to Dummett, (PNP), applied to numerical predications such as the leaves are 1,000' is the key premise in Frege's argument against Mill's theory of numbers. But Frege never subscribed to (PNP) and he rejected such numerical predications, and point out how Frege's own semantic theory for plural noun phrases obscures (...) his idea of a relation. (shrink)

This paper presents a formal account of how to determine the discourse relations between propositions introduced in a text, and the relations between the events they describe. The distinct natural interpretations of texts with similar syntax are explained in terms of defeasible rules. These characterise the effects of causal knowledge and knowledge of language use on interpretation. Patterns of defeasible entailment that are supported by the logic in which the theory is expressed are shown to underly temporal interpretation.

This essay examines a recent line of thought in aesthetics that challenges realist-leaning aesthetic theories. According to this line of thought, aesthetic diversity and disagreement are good, and our aesthetic judgments, responses, and attachments are deeply personal and even identity-constituting. These facts are further used to support anti-realist theories of aesthetic normativity. I aim to achieve two goals: (1) to disentangle arguments concerning diversity, disagreement, and personality; and (2) to offer realist-friendly replies to all three.

Dummctt argues that classical quantification is illegitimate when the domain is given as the objects which fall under an indefinitely extensible concept, since in such cases the objects are not the required definite totality. The chief problem in understanding this complex argument is the crucial but unexplained phrase 'definite totality' and the associated claim that it follows from the intuitive notion of set that the objects over which a classical quantifier ranges form a set. 'Definite totality' is best understood as (...) disguised plural talk like Cantor's 'consistent multiplicity', although this does not help in understanding how a totality could be anything other than definite. Moreover, contrary to his claims, Dummett's own notion of set is not intuitive and he does not demystify the set-theoretic paradoxes. In conclusion, it is argued that Dummett's context principle is responsible for the incoherent projection of the haziness of a conception of some objects onto reality. (shrink)

There have been many readings of Mead's work, and this paper proposes yet another: Mead, theorist of the social act. It is argued that Mead's core theory of the social act has been neglected, and that without this theory, the concept of taking the attitude of the other is inexplicable and the contemporary relevance of the concept of the significant symbol is obfuscated. The paper traces the development of the social act out of Dewey's theory of the act. According to (...) Mead, Dewey's theory does not sufficiently account for consciousness. Grappling with this problematic leads Mead to several key ideas, which culminate in his theory of the social act. The social act and taking the attitude of the other are then illustrated by the analysis of a game of football. The interpretation presented has two novel aspects: first, symbolisation arises not simply through self taking the attitude of the other, but through the pairing of this attitude with the complementary attitude in self; second, self is able to take the attitude of the other to the extent that self has in actuality or in imagination previously been in the social position of the other. From this standpoint the key issue is how the attitude of self and other become integrated. New directions for empirical research, aimed at advancing this question are outlined. Finally, the paper shows how the social act can contribute to our contemporary concerns about the nature of the symbolic. (shrink)

Many philosophers believe that truth is grounded: True propositions depend for their truth on the world. Some philosophers believe that truth’s grounding has implications for our ontology of time. If truth is grounded, then truth supervenes on being. But if truth supervenes on being, then presentism is false since, on presentism, e.g., that there were dinosaurs fails to supervene on the whole of being plus the instantiation pattern of properties and relations. Call this the grounding argument against presentism. Many presentists (...) claim that the grounding argument fails because, despite appearances, supervenience is compatible with presentism. In this paper, I claim that the grounding argument fails because, despite appearances, truth’s grounding gives the presentist no compelling reason to adopt the sort of supervenience principle at work in the grounding argument. I begin by giving two precisifications of the grounding principle: truthmaking and supervenience. In Sect. 2, I give the grounding argument against presentism. In Sect. 3, I argue that we should distinguish between eternalist and presentist notions of grounding; once this distinction is in hand, the grounding argument is undercut. In Sect. 4, I show how the presentist’s notion of grounding leads to presentist-friendly truthmaking and supervenience principles. In Sect. 5, I address some potential objections. (shrink)

At the heart of John Broome’s research program in the philosophy of normativity is a distinction between reasons, on one hand, and requirements of rationality, on the other. I am a friend of Broome’s view that this distinction is deep and important, and that neither notion can be analyzed in terms of the other. However, I also think there are major challenges that this view is yet to meet. In the first part of the paper, I’ll raise four such challenges, (...) and programmatically indicate how I think such challenges might be headed off. In the second part of the paper, I’ll discuss a third normative notion that Broome is interested in: that of (rules of) correct reasoning. On Broome’s view, correct reasoning is closely tied to requirements of rationality. More particularly, every rule of correct reasoning corresponds to a “basing permission”, which states that it’s rationally permissible to base one attitude on one or more other attitudes. I’ll argue that this proposal can’t be made to work. If I’m right, this suggests that the same kind of pulling-apart that Broome has effected so persuasively with respect to reasons and requirements of rationality needs to be effected again to separate rules of correct reasoning from both of those other categories.

: The debate over when medical research may be performed in developing countries has steered clear of the broad issues of social justice in favor of what seem more tractable, practical issues. A better approach will reframe the question of justice in international research in a way that makes explicit the links between medical research, the social determinants of health, and global justice.

An approach to implementing variational Bayesian inference in biological systems is considered, under which the thermodynamic free energy of a system directly encodes its variational free energy. In the case of the brain, this assumption places constraints on the neuronal encoding of generative and recognition densities, in particular requiring a stochastic population code. The resulting relationship between thermodynamic and variational free energies is prefigured in mind–brain identity theses in philosophy and in the Gestalt hypothesis of psychophysical isomorphism.

Hendricks’ The Impairment Argument (TIA) claims that it is immoral to impair a fetus by causing it to have fetal alcohol syndrome (FAS). Since aborting a fetus impairs it to a greater degree than causing it to have FAS, then abortion is also immoral. In this article, I argue that TIA ought to be rejected. This is because TIA can only succeed if it explains why causing an organism to have FAS impairs it to a morally objectionable degree, entails that (...) abortion impairs an organism to a morally objectionable and greater degree than causing FAS, and satisfies The Impairment Principle’s ceteris paribus clause. In order to do all three things, TIA must presuppose some theory of well-being. Even then, no theory of well-being accomplishes all three tasks that TIA must in order to succeed. However, even if this is false and TIA can meet all three objectives by presupposing some theory of well-being, it would not do very much to advance the debate about the morality of abortion. As I argue, TIA would essentially restate well-established arguments against abortion based on whatever theory of well-being it must presuppose in order to be successful. (shrink)

We analyse the tensions in a hybrid collaboration and how these are mitigated using boundary-spanning community impact, leading to compatibility between distinctive institutional logics. Our qualitative longitudinal study undertaken during 2011–2016 involved reviewing literature and archival data, key informant interviews, workshop and focus groups. We analysed common themes within the data, relating to our two research questions concerning how and why hybrids collaborate, and how resulting tensions are mitigated. The findings suggest a viable model of service delivery termed hybridized collaboration (...) in which the inherent tensions from different institutional logics do not prevent success. Paradoxically, multiple logics are a basis for the partnership’s existence, but the ability to achieve different and occasionally conflicting aims simultaneously can be difficult, resulting in tensions. We offer two novel insights. First, we highlight how social enterprise hybrids collaborate locally and in multi-organizational relationships. We found that the initial opportunity to collaborate was catalysed by the existence of shared objectives. Pre-existing relationships between organizations, and the existence of synergistic capabilities also influence the choice of partners. Secondly, we identify how tensions arise, and are mitigated via several factors including the pre-existing relationships, allowing for regular “spaces of negotiation” between collaborators, the shared social mission, community social impact, the resulting public relations, and shared resources and knowledge.

Epistemologists typically assume that the acquisition of knowledge from testimony is not threatened at the stage at which audiences interpret what proposition a speaker has asserted. Attention is instead typically paid to the epistemic status of a belief formed on the basis of testimony that it is assumed has the same content as the speaker’s assertion. Andrew Peet has pioneered an account of how linguistic context sensitivity can threaten the assumption. His account locates the threat in contexts in which an (...) audience’s evidence under-determines which proposition a speaker is asserting. I argue that Peet’s epistemic uncertainty account of the threat is mistaken and I propose an alternative. The alternative locates the threat in contexts that provide factors that give audiences a mistaken psychological certainty or confidence that a speaker has asserted a proposition she has not. (shrink)
