Both utilitarian and deontological moral theories locate the source of our moral beliefs in the wrong sorts of considerations. One way this failure manifests itself, we argue, is in the ways these theories analyze the proper human relationship toward the non-human environment. Another, more notorious, manifestation of this failure is found in Derek Parfit's Repugnant Conclusion. Our goal is to explore the connection between these two failures, and to suggest that they are failures of act-centered moral theories in general. As (...) such, they cannot be fixed by simply developing a better version of such a theory. Virtue-based theories, we suggest, provide a more promising alternative. (shrink)

The Reliability Challenge to moral non-naturalism has received substantial attention recently in the literature on moral epistemology. While the popularity of this particular challenge is a recent development, the challenge has a long history, as the form of this challenge can be traced back to a skeptical challenge in the philosophy of mathematics raised by Paul Benacerraf. The current Reliability Challenge is widely regarded as the most sophisticated way to develop this skeptical line of thinking, making the Reliability Challenge the (...) strongest epistemic challenge to normative nonnaturalism. In this paper, I argue that the innovations that have occurred since Benacerraf’s statement of the challenge are misconceived and confused in a number of ways. The Reliability Challenge is not the most potent epistemic challenge to moral non-naturalism. The most potent challenge comes from the fact that there is a causal condition on knowledge – or, more precisely, a becaual condition – that non-natural moral facts cannot satisfy. (shrink)

I argue that there is a wide variety of epistemic norms, distributed along two different spectra. One spectrum runs from the ideal to the practical and concerns the extent to which it is possible to follow the norm given our cognitive and epistemic limitations. The other spectrum runs from thin to thick and concerns the extent to which the norm concerns facts about our beliefs over and above the content of the belief. Many putative epistemic norms, such as truth and (...) various conceptions of justification, can be found at different points on the spectra. There is no single obvious privileged point from which to say any of these norms is more fundamental than the others, though there may be some reason to doubt that some of the norms are intrinsically interesting.

The standard view of honesty is a subjectivist one, according to which honesty concerns the facts merely “as the agent sees them”. Against this view, the present paper argues for a non-subjectivist view of honesty. It argues, in particular, that ideal honesty requires not merely expressing what one believes to be true but, moreover, expressing what is true. In that case, though one can be honest to an extent while merely expressing what one believes to be true, one cannot be (...) ideally honest without expressing the truth. (shrink)

This article deals with an object of Philosophy, strictly the Philosophy of Language, which concerns the study of the logic and of the dialectics. So, it proposes to analyze the dialectic-logical conceptual aspects in the Corpus Hermeticum 12.12-14a in comparison with the logical texts of the Stoicorum Veterum Fragmenta, in order to find supposed sources conformed with the hermetic text, and know how they were re-worked in it. For that, the references, descriptions and quotations of Sextus Empiricus and of Diocles (...) Magnes, apud Diogenes Laertius, they constitute important sources on the philosophical doctrines of Zenon, Cleanthes and Crysippus. One considers that the doctrine of the first part of the Corp. Herm. 12 is, often, Platonic. Nevertheless, there are realized signs of influences of stoicism. The conception about νοῦς [nous] in the man is from Platonic origin, but the expression προφοριϰὸς λόγος [prophorikos logos] is certainly Stoic. Then, the Corp. Herm. 12 is a product of a middle-stoicism or middle-Platonism, stoicizing Platonism or platonizing Stoicism, which cannot have appeared before the c. I B.C.E. Specifically, the article is interested in the dialectic-logical problem that involve some Stoic concepts, as λόγος, προφοριϰὸς λόγος, φωνή [phōnē], as well as the problem of the connective propositional logic in the platonizing process through the doctrine of νοῦς themed in the Corp. Herm. 12.12-14a, assuming a theological dimension and a divine character of λόγος, by being ἐνδιάϑετος λόγος, the thought that exists ἐν τῇ διαϑέσει, ἐν τῷ νῷ. (shrink)

The Skillfulness of Virtue provides a new framework for understanding virtue as a skill, based on psychological research on self-regulation and expertise. Matt Stichter lays the foundations of his argument by bringing together theories of self-regulation and skill acquisition, which he then uses as grounds to discuss virtue development as a process of skill acquisition. This account of virtue as skill has important implications for debates about virtue in both virtue ethics and virtue epistemology. Furthermore, it engages seriously with criticisms (...) of virtue theory that arise in moral psychology, as psychological experiments reveal that there are many obstacles to acting and thinking well, even for those with the best of intentions. Stichter draws on self-regulation strategies and examples of deliberate practice in skill acquisition to show how we can overcome some of these obstacles, and become more skillful in our moral and epistemic virtues.

It seems like experience plays a positive—even essential—role in generating some knowledge. The problem is, it’s not clear what that role is. To see this, suppose that when your visual system takes in information about the world around you it skips the experience step and just automatically and immediately generates beliefs in you about your surroundings. A lot of philosophers think that, in such a case, you would (or at least could) still know, via perception, about the world around you. (...) But then that raises the question: What epistemic role was the experience playing? How did it contribute to your knowledge of your surroundings? Philosophers have given many different answers to these questions. But, for various reasons, none of them has really stuck. In this paper I offer and defend a different answer to these questions—a solution to the problem—which avoids the pitfalls of other answers. I argue that experience is, all by itself, a kind of knowledge—it’s what Bertrand Russell (1912) calls “knowledge of things”. So I argue that experience helps generate knowledge simply by being knowledge. (shrink)

Since its resurgence in the 1990s, character education has been subject to a bevy of common criticisms, including that it is didactic and crudely behaviorist; premised on a faulty trait psychology; victim‐blaming; culturally imperialist, racist, religious, or ideologically conservative; and many other horrible things besides. Matt Ferkany and Benjamin Creed examine an intellectualist Aristotelian form of character education that has gained popularity recently and find that it is largely not susceptible to such criticisms. In this form, character education is education (...) for practically intelligent virtue, or the intrinsically motivated and psychically harmonious exercise of robust and stable traits involving practical intelligence conducive to individual and collective human flourishing.

When we experience the world – see, hear, feel, taste, or smell things – we gain all sorts of knowledge about the things around us. And this knowledge figures heavily in our reasoning about the world – about what to think and do in response to it. But what is the nature of this knowledge? On one commonly held view, all knowledge is constituted by beliefs in propositions. But in this paper I argue against this view. I argue that some (...) knowledge is constituted, not by beliefs in propositions, but by awareness of properties and objects. To make my case, I focus on the role of visual perception in reasoning. I start by introducing a principle about the relationship between knowledge and reasoning, which says that to learn something new by reasoning, one must know the bases of one’s reasoning. Then I argue that in some cases of genuine, knowledge-conferring reasoning, the bases of our reasoning are not propositions that we believe; rather, they’re properties or objects that we see. Thus, I conclude that some such knowledge is non-propositional and is rather what some call “knowledge of things”. (shrink)

Subjectivity is that feature of consciousness whereby there is something it is like for a subject to undergo an experience. One persistent challenge in the study of consciousness is to explain how subjectivity relates to, or arises from, purely physical brain processes. But, in order to address this challenge, it seems we must have a clear explanation of what subjectivity is in the first place. This has proven challenging in its own right. For the nature of subjectivity itself seems to (...) resist straightforward characterization. In this paper, I won't address how subjectivity relates to the physical. Instead, I'll address subjectivity itself. I'll do this by introducing and defending a model of subjectivity based on self-acquaintance. My model does not purport to reduce, eliminate, or naturalize subjectivity, but it does make subjectivity more tractable, less paradoxical, and perhaps less dubious to those averse to obscurity.

These days almost everyone seems to think it obvious that equality of opportunity is at least part of what constitutes a fair society. At the same time they are so vague about what equality of opportunity actually amounts to that it can begin to look like an empty term, a convenient shorthand for the way jobs should be allocated, whatever that happens to be. Matt Cavanagh offers a highly provocative and original new view, suggesting that the way we think about (...) equality and opportunity should be radically changed. (shrink)

This paper argues that a sweatshop worker's choice to accept the conditions of his or her employment is morally significant, both as an exercise of autonomy and as an expression of preference. This fact establishes a moral claim against interference in the conditions of sweatshop labor by third parties such as governments or consumer boycott groups. It should also lead us to doubt those who call for MNEs to voluntarily improve working conditions, at least when their arguments are based on (...) the claim that workers have a moral right to such improvement. These conclusions are defended against three objections: 1) that sweatshop workers' consent to the conditions of their labor is not fully voluntary, 2) that sweatshops' offer of additional labor options is part of an overall package that actually harms workers, 3) that even if sweatshop labor benefits workers, it is nevertheless wrongfully exploitative.

Julia Annas is one of the few modern writers on virtue that has attempted to recover the ancient idea that virtues are similar to skills. In doing so, she is arguing for a particular account of virtue, one in which the intellectual structure of virtue is analogous to the intellectual structure of practical skills. The main benefit of this skill model of virtue is that it can ground a plausible account of the moral epistemology of virtue. This benefit, though, is (...) only available to some accounts of virtue. Annas claims that Aristotle rejects this skill model of virtue, and so the model of virtues as a skill that Annas endorses for the modern virtue theory is Socratic. This paper argues that while Aristotle rejects the Socratic model of virtue as a skill, he does not reject the model of virtue as a skill altogether. Annas has mischaracterized Aristotle's position on the skill model, because she has not recognized that Aristotle endorses a different account of the structure of skill than the one put forth by Socrates. In addition, recent research on expertise provides an account of skills very much at odds with the description of skills offered by Annas, but similar to the account endorsed by Aristotle. Contrary to Annas, not only is the skill model of virtue compatible with a neo-Aristotelian account of virtue, but it also appears that basing a skill model of virtue on a Socratic account of virtue is likely to prove unsuccessful.

Though one of anti-intellectualism’s key historical figures, Henri Bergson’s thought has not played a significant role in ongoing discussions of that topic. This paper attempts to help change this situation by discussing the notion at the centre of Bergson’s anti-intellectualism (namely, intuition) alongside the notion at the centre of a central form of contemporary anti-intellectualism (namely, know-how or skill). In doing so, it focuses on perhaps the most common objection to both Bergson and contemporary anti-intellectualists: that their anti-intellectualisms are rather (...) forms of irrationalism. It argues that in fact only a narrow charge of irrationalism applies to Bergsonian intuition and that a form of contemporary anti-intellectualism may offer help in responding to this remaining accusation.

This paper argues for a reinterpretation of the skill analogy in virtue ethics. It argues that the skill analogy should not be understood as proposing that being virtuous is analogous to possessing a practical skill but, rather, as proposing that being virtuous is analogous to being a good occupant of a skill-involving role. The paper argues for this by engaging with various standard objections to the analogy, two recent defences of it, and Aristotle’s treatment of it in developing his account (...) of virtue in the Nicomachean Ethics. It aims to show that neither virtue nor the skill analogy is correctly understood without recourse to the notion of a role and that once we have recourse to that notion, many objections to the analogy are met.

Philosophers of perception frequently assume that we see actual states of affairs, or facts. Call this claim factualism. In his book, William Fish suggests that factualism is supported by phenomenological observation as well as by experimental studies on multiple object tracking and dynamic feature-object integration. In this paper, I examine the alleged evidence for factualism, focusing mainly on object detection and tracking. I argue that there is no scientific evidence for factualism. This conclusion has implications for studies on the phenomenology (...) and epistemology of visual perception. (shrink)

The prominence of Bayesian modeling of cognition has increased recently largely because of mathematical advances in specifying and deriving predictions from complex probabilistic models. Much of this research aims to demonstrate that cognitive behavior can be explained from rational principles alone, without recourse to psychological or neurological processes and representations. We note commonalities between this rational approach and other movements in psychology – namely, Behaviorism and evolutionary psychology – that set aside mechanistic explanations or make use of optimality assumptions. Through (...) these comparisons, we identify a number of challenges that limit the rational program's potential contribution to psychological theory. Specifically, rational Bayesian models are significantly unconstrained, both because they are uninformed by a wide range of process-level data and because their assumptions about the environment are generally not grounded in empirical measurement. The psychological implications of most Bayesian models are also unclear. Bayesian inference itself is conceptually trivial, but strong assumptions are often embedded in the hypothesis sets and the approximation algorithms used to derive model predictions, without a clear delineation between psychological commitments and implementational details. Comparing multiple Bayesian models of the same task is rare, as is the realization that many Bayesian models recapitulate existing (mechanistic level) theories. Despite the expressive power of current Bayesian models, we argue they must be developed in conjunction with mechanistic considerations to offer substantive explanations of cognition. We lay out several means for such an integration, which take into account the representations on which Bayesian inference operates, as well as the algorithms and heuristics that carry it out. We argue this unification will better facilitate lasting contributions to psychological theory, avoiding the pitfalls that have plagued previous theoretical movements. (shrink)

The sensorimotor theory of vision and visual consciousness is often described as a radical alternative to the computational and connectionist orthodoxy in the study of visual perception. However, it is far from clear whether the theory represents a significant departure from orthodox approaches or whether it is an enrichment of it. In this study, I tackle this issue by focusing on the explanatory structure of the sensorimotor theory. I argue that the standard formulation of the theory subscribes to the same (...) theses of the dynamical hypothesis and that it affords covering-law explanations. This however exposes the theory to the mere description worry and generates a puzzle about the role of representations. I then argue that the sensorimotor theory is compatible with a mechanistic framework, and show how this can overcome the mere description worry and solve the problem of the explanatory role of representations. By doing so, it will be shown that the theory should be understood as an enrichment of the orthodoxy, rather than an alternative. (shrink)

Modern physics has provided a range of motivations for holding time to be fundamentally undirected. But how does a temporally adirectional metaphysics, or ‘C-theory’ of time, fit with the time of experience? In this chapter, I look at what kind of problem human time poses for C-theories. First, I ask whether there is a ‘hard problem’ of human time: whether it is in principle impossible to have the kinds of experience we do in a temporally adirectional world. Second I consider (...) the ‘easy problem’: how specific directed aspects of our temporal experience are to be explained by C-theorists. This leads to a greater issue: is there such a thing as an experience of time direction at all to even be explained? I show how the kinds of experience we have that we typically associate with the idea of time being directed can be accommodated within a directionless picture of time. (shrink)

:This essay seeks to defend the claim that political philosophy ought to be appropriately guided by the phenomenon of politics that it seeks to both offer a theory of and, especially in its normative guise, offer a theory for. It does this primarily through the question of political values. It begins by arguing that for any value to qualify as a value for the political domain, it must be intelligible in relation to the constitutive features of politics as a human (...) activity. It then examines the extent to which the preconditions for the realization of values in practice ought to figure in our considerations as to whether they are values that fit or belong to our social world. We can understand these parts of the essay as responding to two related questions, respectively: Is this a political value at all? — which is to ask, is it a value that is appropriate for the political realm?; and then Is this a political value for us? The final section responds to the often-made complaint that political philosophy ought not to make any concessions to the actual world of politics as it really is, arguing that attending to the realities of politics, and in particular the constitutive conditions of political activity, gives meaning to the enterprise as the theorization of politics. Furthermore those same conditions provide the limits of intelligibility beyond which ideals and values can no longer be, in any meaningful sense, ideals and values for the political sphere. (shrink)

On an account of virtue as skill, virtues are acquired in the ways that skills are acquired. In this paper I focus on one implication of that account that is deserving of greater attention, which is that becoming more skillful requires learning from one’s failures, but that turns out to be especially challenging when dealing with moral failures. In skill acquisition, skills are improved by deliberate practice, where you strive to correct past mistakes and learn how to overcome your current (...) limitations. A similar story applies to virtue acquisition, as moral failures will be a part of anyone’s life, and we will all have to learn from these experiences. However, despite the importance of being able to learn from our mistakes, this is very difficult in practice, given that failure of any kind can be distressing, and especially so for moral failure. The distress created by a recognition of moral failure often prompts responses of anger, avoidance, or defensiveness; rather than attempts to make amends and when necessary to work on self-improvement. The most potentially distressing response to moral failure is shame, as it is often associated with defensiveness. It is here where emotion regulation will be important to manage that distress, and I focus on the skill of emotion differentiation. I argue that emotion differentiation is a promising strategy for distinguishing the emotions we may experience in the wake of failure, including shame, and to encourage those emotions that motivate self-improvement. Thus, emotion regulation is important for virtue acquisition. (shrink)

Some philosophers claim that propositions are simple—i.e., lack parts. In this paper, I argue that this claim is mistaken. I start with the widely accepted claim that propositions are the objects of beliefs. Then I argue that the objects of beliefs have parts. Thus, I conclude that propositions are not simple. My argument for the claim that the objects of beliefs have parts derives from the fact that beliefs are productive and systematic. This fact lurks in the background of debates (...) about the metaphysics of propositions. But its import for these debates has yet to be fully appreciated. So here I bring the point to the fore, and thus make manifest a powerful argument against simple propositions. (shrink)

Cognitive representations are typically analysed in terms of content, vehicle and format. While current work on formats appeals to intuitions about external representations, such as words and maps, in this paper we develop a computational view of formats that does not rely on intuitions. In our view, formats are individuated by the computational profiles of vehicles, i.e., the set of constraints that fix the computational transformations vehicles can undergo. The resulting picture is strongly pluralistic, it makes space for a variety (...) of different formats, and is intimately tied to the computational approach to cognition in cognitive science and artificial intelligence.

What would it be for a process to happen backwards in time? Would such a process involve different causal relations? It is common to understand the time-reversal invariance of a physical theory in causal terms, such that whatever can happen forwards in time can also happen backwards in time. This has led many to hold that time-reversal symmetry is incompatible with the asymmetry of cause and effect. This article critiques the causal reading of time reversal. First, I argue that the (...) causal reading requires time-reversal-related models to be understood as representing distinct possible worlds and, on such a reading, causal relations are compatible with time-reversal symmetry. Second, I argue that the former approach does, however, raise serious sceptical problems regarding the causal relations of paradigm causal processes and as a consequence there are overwhelming reasons to prefer a non-causal reading of time reversal, whereby time reversal leaves causal relations invariant.

This article attempts to determine whether there exists a coherent, plausible, and ultimately compelling explication of what it is to act neutrally. I argue that there is – an account I label neutrality of volition, and according to which an actor acts non-neutrally where she either acts for the purpose of differentially helping or hindering a particular party in a given contest, or acts or in the belief that there is a substantial likelihood that her action will have this effect. (...) Along the way, I suggest that political philosophers concerned with whether justice requires that the state’s laws and policies be publicly justifiable, as well as legal commentators who note that oftentimes laws of general application have disparate impacts, would do well to cease framing their arguments in the language of neutrality. I conclude by arguing that debate over the proper interpretation of neutrality is not merely a matter of semantics. Having identified an account of neutrality that aligns with our ordinary understanding of the concept, and which is also internally consistent, we have access to a conceptual tool that we can use to make better sense of a wide array of actions in the political sphere and beyond, while also avoiding an unhelpful conflation of neutrality with distinct concepts such as fairness, public justifiability, anti-perfectionism, equal impact, and non-discrimination.

Humans have a flexible and accurate ability to coordinate their movement in time with external rhythms. However, it remains unclear when and how, during their development, human children acquire the ability to adjust tempo and control the timing of their movement toward others. A previous study suggested that such self-regulation of coordination develops at around 18 and 30 months after birth. In this study, we investigated the performance of 24-month-old children and compared their data with those of 18- and 30-month-olds (...) provided in our previous study. In the joint-drumming task, each child was enticed to drum under four conditions [partner: mother or robot; speed: 400 or 600 ms inter-stimulus-interval ]. The most pivotal test condition was the 600 ms ISI speed condition. We found that from the age of 24 months, children try to slow down their drumming tempo toward the 600 ms ISI speed condition, regardless of the drumming partner. On the other hand, significant timing control toward the onset of the 600 ms ISI condition was observed from the age of 30 months. This implies that both motor and cognitive mechanisms are required for flexible tempo adjustment and accurate synchronization and that these develop gradually among 18-, 24-, and 30-month-olds.

In this paper I explore buck passing analyses of deontic properties in terms of reasons. The preferred analysis is that the permissibility/impermissibility/optionality/requiredness/etc. of some agent's acting is to be couched in terms of reasons to respond in some way to that agent's action, or the prospect thereof. Along the way I try to accommodate supererogation, wrong kinds of reasons objections, and commonly accepted inferences in deontic logic.

When contemporary philosophers discuss the nature of knowledge, or conduct debates that the nature of knowledge is relevant to, they typically treat all knowledge as propositional. However, recent introductory epistemology texts and encyclopedia entries often mention three kinds of knowledge: (i) propositional knowledge, (ii) abilities knowledge, and (iii) knowledge of things/by acquaintance. This incongruity is striking for a number of reasons, one of which is that what kinds of knowledge there are is relevant to various debates in philosophy. In this (...) paper I focus on this point as it relates to the third kind of knowledge mentioned above – knowledge of things. I start by supposing that we have knowledge of things, and then I show how this supposition reshapes various debates in philosophy. (shrink)

Evolutionary Debunking Arguments purport to show that our moral beliefs do not amount to knowledge because these beliefs are “debunked” by the fact that our moral beliefs are, in some way, the product of evolutionary forces. But there is a substantial gap in this argument between its main evolutionary premise and the skeptical conclusion. What is it, exactly, about the evolutionary origins of moral beliefs that would create problems for realist views in metaethics? I argue that evolutionary debunking arguments are (...) best understood as offering up defeaters for our moral beliefs. Moreover, the defeater in question is a paradigmatic instance of undercutting defeat. If anything is an undercutting defeater, then learning about the evolutionary origins of our moral beliefs is a defeater for those beliefs. (shrink)
