In this paper I examine a recent incarnation of common objection to evidentialism. According to this common objection, evidentialism gives the wrong verdicts in cases where the subject has been irresponsible in inquiry. Sandy Goldberg (2021) has argued that a particularly vivid instance of this problem occurs when an individual violates normative expectations that have been placed on them in their inquiry. Having laid out Goldberg’s case, I argue that the desirable verdicts can be better attained by endorsing (...) evidentialism and supplementing it with an account of robust justification that I have defended elsewhere.

One emerging issue in contemporary epistemology concerns the relation between animal knowledge, which can be had by agents unable to take a view on the epistemic status of their attitudes, and reflective knowledge, which is only available to agents capable of taking such a view. Philosophers who are open to animal knowledge often presume that while many of the beliefs of human adults are formed unreflectively and thus constitute mere animal knowledge, some of them—those which become subject of explicit scrutiny (...) or are the result of a deliberative effort—may attain the status of reflective knowledge. According to Sanford Goldberg and Jonathan Matheson (2020), however, it is impossible for reflective subjects to have mere animal knowledge. If correct, their view would have a number of repercussions, perhaps most notably the vindication of a dualism about knowledge, which would frustrate attempts to provide a unified account of knowledge-attributions to human adults, very young children, and non-human animals. I discuss Goldberg and Matheson’s proposal, outline some of the ways in which it is insightful, and argue that it is ultimately unsuccessful because it neglects the inherent temporal dimension of knowledge acquisition. While the article is pitched as a reply to Goldberg and Matheson, its primary aim is to highlight significant connections between the debates on the relation between animal and reflective knowledge, propositional and doxastic justification, and the theory of epistemic defeat.

Gignac and Zajenkowski (2020) find that “the degree to which people mispredicted their objectively measured intelligence was equal across the whole spectrum of objectively measured intelligence”. This Comment shows that Gignac and Zajenkowski’s (2020) finding of homoscedasticity is likely the result of a recoding choice by the experimenters and does not in fact indicate that the Dunning-Kruger Effect is a mere statistical artifact. Specifically, Gignac and Zajenkowski (2020) recoded test subjects’ responses to a question regarding self-assessed comparative IQ onto a (...) linear IQ scale when a normal IQ scale would likely have been more appropriate. More generally, researchers studying self-assessed intelligence should be aware of potential measurement problems that may arise when transforming an ordinal scale onto an interval scale. (shrink)

Ignorance usually excuses from responsibility, unless the person is culpable for the ignorance itself. Since a lot of wrongdoing occurs in ignorance, the question of what makes ignorance culpable is central for a theory of moral responsibility. In this article I examine a prominent answer, which I call the ‘volitionalist tracing account,’ and criticize it on the grounds that it relies on an overly restrictive conception of responsibility‐relevant control. I then propose an alternative, which I call the ‘capacitarian conception of (...) control,’ and on the basis of it I advance an account of culpable ignorance that avoids the skeptical upshots of the volitionalist proposal. If correct, my account establishes three important truths: agents can be directly in control of their ignorance, they can be directly responsible for more than actions and omissions, and their moral obligations extend beyond the performance of intentional actions and omissions.

In this paper I sketch a socially situated account of responsible agency, the main tenet of which is that the powers that constitute responsible agency are themselves socially constituted. I explain in detail the constitution relation between responsibility-relevant powers and social context and provide detailed examples of how it is realized by focusing on what I call ‘expectations-generating social factors’ such as social practices, cultural scripts, social roles, socially available self-conceptions, and political and legal institutions. I then bring my account (...) to bear on the debate about the exculpatory potential of moral ignorance. I show that a prominent position in this debate – the position that denies that moral ignorance exculpates – is grounded on an individualistic and acontextualist conception of moral capacities, moral cognition, and blameworthiness, and that this conception leads those philosophers who endorse it to make a number of questionable claims regarding the ability of ordinary agents to overcome their moral ignorance and the culpability they bear for the latter. I conclude by indicating how my socially situated account addresses the issue of moral ignorance. (shrink)

In this article I discuss David Shoemaker’s recently published piece “Responsibility: The State of the Question. Fault Lines in the Foundations.” While agreeing with Shoemaker on many points, I argue for a more unified diagnosis of the seemingly intractable debates that plague (what I call) “responsibility studies.” I claim that, of the five fault lines Shoemaker identifies, the most basic one is about the role that the notion of deserved harm should play in the theory of moral responsibility. I argue (...) that the deep divide between those theorists who affirm and those who deny that moral responsibility is essentially about the justification of desert thus understood can be traced to the disagreement about whether the focus on the reactive attitudes by itself entails that moral responsibility has nothing to do with traditional questions about desert and free will. I then show that the seeming intractableness of the other four fault lines Shoemaker identifies is expectable and explicable in light of this more basic disagreement. After this diagnostic work, I conclude by suggesting a solution to the “morass” that has taken over responsibility studies: theorists working in the field should acknowledge that it has effectively bifurcated into two discrete subareas, which I suggest calling “retribution studies” and “interpersonal studies.” -/- .

Thomas Hurka, in his book Virtue, Vice, and Value, and elsewhere, develops a recursive analysis of higher-order pleasures and pains. The account leads Hurka to some potentially controversial conclusions. For instance, Hurka argues on its basis that some states are both good and evil and also that the view he calls the conditionality view is false. In this paper, I argue that Hurka’s formulation of the recursive account is unusual and inelegant, and that Hurka reaches his conclusions only because of (...) its peculiar aspects. I provide an alternative recursive account which is similar in spirit to Hurka’s but which is theoretically elegant and does not entail those conclusions. (shrink)

In this article, we re-examine Pascal’s Mugging, and argue that it is a deeper problem than the St. Petersburg paradox. We offer a way out that is consistent with classical decision theory. Specifically, we propose a “many muggers” response analogous to the “many gods” objection to Pascal’s Wager. When a very tiny probability of a great reward becomes a salient outcome of a choice, such as in the offer of the mugger, it can be discounted on the condition that there (...) are other symmetric, non-salient rewards that one may receive if one chooses otherwise.

Consent theory in sexual ethics, Jonathan Ichikawa argues, has a Euthyphro problem. -/- It is widely held that sexual violations are explicable in terms of nonconsensual sexual contact. But a notion of consent adequate to explain many moral judgments typical of sexual ethics — a notion that vindicates the idea that consent cannot be coerced, that it must be sober, that children cannot consent to sex with adults, etc. — cannot, Ichikawa argues, be articulated, motivated, or explained in a (...) way independently of moral judgments about sexual wrongs. Consequently, if there is as tight a connection between consent and sexual violation as many people think there is, there is good reason to suppose that that connection must ultimately explain consent in terms of sexual wronging, rather than vice versa. The paper highlights some costs and drawbacks to this horn of the Euthyphro dilemma in sexual ethics. One central upshot of the argument will be that mainstream accounts of sexual ethics fail in their explanatory ambitions. Consent cannot play its canonical explanatory role. (shrink)

To what extent do we value future generations? It may seem from our behavior that we don’t value future generations much at all, at least in relation to how much we value present generations. However, in his book _Death and the Afterlife_, Samuel Scheffler argues that we value the future even _more_ than we value the present, even though this is not immediately apparent to us. If Scheffler’s argument is sound, then it has important ramifications: It would give us a (...) strong motivation to put more energy into abating environmental crises like climate change, and it supports at least a limited form of ethical _longtermism_. However, in this paper, I show that Scheffler’s argument is fallacious. Scheffler claims that we do not regard the fact that we in the present generation will all die relatively soon as a catastrophe, but we do regard the non-existence of future generations as a catastrophe. But the particular scenario used by Scheffler to illustrate this point—the plot of the book _The Children of Men_—is one in which _both_ the present generation will perish _and_ there will be no future generations, and it is this _conjunction_ that is catastrophic, thus giving no information about which is worse. I suggest other ways to compare our valuations of present and future generations, and recommend that philosophers who are interested in the moral psychology of how we value future generations ought to engage with social science, as it is an empirical issue.

The question of how disability affects wellbeing has occupied a number of philosophers in recent years. However, this literature has proceeded without a careful examination of the fairly vast empirical research on the topic. In this paper, I review the scholarly literature and discuss some philosophically-relevant aspects of it. On average, those with disabilities have a significantly lower level of wellbeing than those without disabilities. Furthermore, there is strong evidence that this reduction in wellbeing is not due entirely to ableist (...) factors. Hence, I argue that it shows that the Mere Difference View of disability is most likely false. However, the literature indeed shows that disabled people typically live good lives. Thus, despite its rejection of the Mere Difference View, it still upholds a disability-affirmative view. These findings allow for a measured critique of some of Peter Singer’s writings on disability.

All ordinary decisions involve some risk. If I go outside for a walk, I may trip and injure myself. But if I don’t go for a walk, I slightly increase my chances of cardiovascular disease. Typically, we disregard most small risks. When, for practical purposes, is it appropriate for one to ignore risk? This issue looms large because many activities performed by those in wealthy societies, such as driving a car, in some way risk contributing to climate harms. Are these (...) activities morally appropriate? -/- In this paper, I first summarize and respond to some arguments that purport to show that it is appropriate to ignore or discount very small risks. I argue that because our rationality is bounded, it is impossible for us to include every small risk in our decision-making process, and so we may reasonably use heuristics to guide many decisions. However, contrary to some thinkers, I argue that this does not violate the spirit of expected value theory; it merely shows that we should adopt a so-called "two-level" view. Our use of heuristics allows for the reasonable ignoring of some risks, and this perhaps explains why one might be inclined to think that individual climate-related risks are negligible. However, virtually all greenhouse-gas emitting activities in fact have some climate risk on the negative side of the ledger, and the use of heuristics does not permit the general ignoring of climate-change-related risk by individuals on grounds of expediency of judgment and decision-making.

In this paper I revisit Gregory Kavka’s Toxin Puzzle and propose a novel solution to it. Like some previous accounts, mine postulates a tight link between intentions and reasons but, unlike them, in my account these are motivating rather than normative reasons, i.e. reasons that explain (rather than justify) the intended action. I argue that sensitivity to the absence of possible motivational explanations for the intended action is constitutive of deliberation-based intentions. Since ordinary rational agents display this sensitivity, when placed (...) in the toxin scenario they will believe that there is no motivational explanation for actually drinking the toxin and this is why they can’t form the intention to drink it in the first place. I thus argue that my Motivating-Explanatory Reason Principle correctly explains the toxin puzzle, thereby revealing itself as a genuine metaphysical constraint on intentions. I also explore at length the implications of my account for the nature of intention and rational agency. (shrink)

How a group G can know that p has been the subject of much investigation in social epistemology in recent years. This paper clarifies and defends a form of non-supervenient, non-summative group knowledge: G can know that p even if none of the members of G knows that p, and whether or not G knows that p does not locally supervene on the mental states of the members of G. Instead, we argue that what is central to G knowing that (...) p is whether G has an epistemic structure that is functioning appropriately in accord with the action-related purposes of the group, and this structure may include non-agential elements such as devices that retain or process information. We argue that recent objections to non-summative group knowledge given by Jennifer Lackey do not in fact succeed in undermining the view, but do help to clarify the nature of non-summative group knowledge. The main upshot of our response to Lackey’s objections is that groups put their knowledge into action in ways that often differ from how individuals do so, and social epistemologists should be careful to notice these differences, especially insofar as groups often structure themselves by employing various epistemically-relevant devices.

Non‐reflectivist real self views claim that people are morally responsible for all and only those bits of conduct that express their true values and cares, regardless of whether they have endorsed them or not. A phenomenon that is widely cited in support of these views is inverse akrasia, that is, cases in which a person is praiseworthy for having done the right thing for the right reasons despite her considered judgment that what she did was wrong. In this paper I (...) show that non‐reflectivist real self views are problematic by focusing on the related but neglected phenomenon of inverse enkrasia, which occurs when an agent commits wrongdoing by following a mistaken evaluative judgment that, unbeknownst to her, runs contrary to her true values and cares. Intuitively, inverse enkratics are blameworthy for their actions although the latter don't express their real selves; therefore, non‐reflectivist real self views are false. I assess the implications of this result for the viability of the quality of will paradigm and conclude that the latter survives unscathed to the problems besetting real self views. The lesson is that defenders of the quality of will paradigm should stop talking about real selves altogether. (shrink)

There has been much work on ontological dependence in recent literature. However, relatively little of it has been dedicated to the ways in which individual physical objects may depend on other distinct, non-overlapping objects. This paper gives several examples of such object-dependence and distinguishes between different types of it. The paper also introduces and refines the notion of an n-tet. N-tets (typically) occur when there are object-dependence relations between n objects. I claim that the identity (or, rather, what I call (...) the n-dentity) conditions for n-tets are not grounded in the individual identity conditions of each of the n objects, but instead are metaphysically basic. The paper then briefly discusses some ramifications of accepting object-dependence (and n-tets) on the philosophy of biology, ethics, and logic. (shrink)

Jesper Kallestrup has provided an insightful response to our paper, “Epistemic Structure in Non-Summative Social Knowledge”. Kallestrup identifies some important issues pertaining to our non-summative, non-supervenient account of group knowledge which we did not address in our original paper. Here, we develop our view further in light of Kallestrup’s helpful reply.

This paper develops a Humean environmental meta-ethic to apply to the animal world and, given some further considerations, to the rest of nature. Our interpretation extends Hume’s account of sympathy, our natural ability to sympathize with the emotions of others, so that we may sympathize not only with human beings but also animals, plants and ecosystems as well. Further, we suggest that Hume has the resources for an account of environmental value that applies to non-human animals, non-sentient elements of nature (...) as well as nature as whole even without the appeal to sympathy. One consequence of this approach is that the reasons for promoting animal welfare need not be restricted to sentientist reasons. (shrink)

Research on the capacity to understand others' minds has tended to focus on representations ofbeliefs,which are widely taken to be among the most central and basic theory of mind representations. Representations ofknowledge, by contrast, have received comparatively little attention and have often been understood as depending on prior representations of belief. After all, how could one represent someone as knowing something if one does not even represent them as believing it? Drawing on a wide range of methods across cognitive science, (...) we ask whether belief or knowledge is the more basic kind of representation. The evidence indicates that nonhuman primates attribute knowledge but not belief, that knowledge representations arise earlier in human development than belief representations, that the capacity to represent knowledge may remain intact in patient populations even when belief representation is disrupted, that knowledge (but not belief) attributions are likely automatic, and that explicit knowledge attributions are made more quickly than equivalent belief attributions. Critically, the theory of mind representations uncovered by these various methods exhibits a set of signature features clearly indicative of knowledge: they are not modality-specific, they are factive, they are not just true belief, and they allow for representations of egocentric ignorance. We argue that these signature features elucidate the primary function of knowledge representation: facilitating learning from others about the external world. This suggests a new way of understanding theory of mind – one that is focused on understanding others' minds in relation to the actual world, rather than independent from it. (shrink)

This paper focuses on an underexplored challenge in infinite ethics. On realistic assumptions, if our universe is infinite, every nomologically possible history is actual and nothing we ever do makes a difference to the moral quality of the world as a whole. Call this thought Every History. This paper unpacks Every History and explores some of its ethical implications. Specifically, I argue that if Every History is true and the universe turns out to be infinite (1) our lives are globally (...) insignificant, (2) moral principles enjoining the promotion of value need to be given an appropriately scope-restricted interpretation, and (3) impersonal consequentialism faces a serious challenge.

This paper looks at Gregory of Nyssa's so-called "bundle theory" sensible individuals and matter (as recently argued by Gerd Van Riel and Thomas Wauters in a 2020 article) amidst the broader context of Gregory's view of created beings and his reception of Neoplatonist, Stoic, and Aristotelian conceptions of particulars and matter. I argue that Gregory's position is closer to an Aristotelian position, despite the parallels to Plotinus and other contemporaneous bundle theory positions: in arguing against prime matter, and insofar as (...) he emphasizes the identity of each kind of created being with its material substrate—understood as a "bundle" of properties—Gregory inadvertently upholds a reading of Aristotle that refutes an ontological notion of prime matter.

According to a prominent narrative, the problem of recognition arises in the modern period in opposition to premodern notions of honor. This chapter invites us to reconsider this narrative by examining two views of honor in ancient Greek thought. I first show that Homeric honor includes contestable norms of reciprocal respect and esteem for individual virtue. I then show how Plato appropriates the Homeric view in his ethical psychology yet articulates a competing view of the nature and value of honor. (...) By showing that ancient Greek honor is more continuous with theories of recognition than has been appreciated, this chapter offers fresh perspectives on a central strand of ancient Greek ethics and its relevance to social and political thought.

I believe that the sort of disagreements we encounter in philosophy—disagreements that often take the form that I have elsewhere called system- atic peer disagreements—make it unreasonable to think that there is any knowledge, or even justified belief, when the disagreements themselves are systematic. I readily acknowledge that this skeptical view is quite controversial; I suspect many are unconvinced. However, I will not be defending it here. Rather, I will be exploring a worry, or set of worries, that arise on (...) the assumption that this view is correct. For if it is unreasonable to think that there is justified belief in contexts of systematic philosophical disagreements, by what right do we continue to advance philosophical claims in such contexts? Indeed, by what right do we believe the philosophical claims we advance? And if we don’t believe them, why do we advance them in the first place? An inability to respond to these worries would leave us with the dis- tinct impression that the practice or activity of philosophy is quite suspect: what sort of practice or activity would have us believe unreasonably, assert unwarrantedly, and perhaps exhibit insincerity to boot?

Definitions of animal welfare often invoke consciousness or sentience. Marian Stamp Dawkins has argued that to define animal welfare this way is a mistake. In Dawkins’s alternative view, an animal with good welfare is one that is healthy and “has what it wants.” The dispute highlights a source of strain on the concept of animal welfare: consciousness-involving definitions are better able to capture the normative significance of welfare, whereas consciousness-free definitions facilitate the validation of welfare indicators. I reflect on how (...) the field should respond to this strain, ultimately recommending against splitting the concept and in favor of consciousness-involving definitions. (shrink)

[Author's note: I am posting this dissertation since it may be of interest to some people working on vagueness and related topics. It does not represent my current views on the topic. I have never attempted to publish any of this work, though I hope some day to return to it.] -/- Philosophers have devoted a lot of attention to vagueness in recent years, but there is still no general consensus about how to resolve the Sorites paradox. Timothy Williamson‘s epistemic (...) view, which claims that our vague terms have unknown sharp boundaries, is the most popular and most controversial current account. No one has shown exactly what is wrong the epistemic view and no one has provided a satisfying alternative to it. These two projects – articulating what is wrong with the epistemic view, and providing a plausible alternative – are the primary goals of this dissertation. -/- Additionally, I survey ordinary intuitions that underlie Sorites paradoxes, and I note how these intuitions inform, and are informed by, a number of deeper philosophical debates in metaphysics, epistemology, philosophy of language, and ethics. In part, this serves as an explanation of why the Sorites paradox has remained so difficult to resolve. -/- The most common objection to the epistemic view – that it provides an unsatisfactory account of the connection between meaning and use – has not been successful in undermining the view. My own objection is a metaphysical, and not a semantic, objection: the epistemic view fails to provide the best explanation of what objects and properties exist. Instead, an eliminativist account of macro-level objects and properties, according to which there are no mountains and there is no property of being lavender-colored, is a better metaphysical account than one that claims that there are mountains and color properties that have sharp boundaries. -/- Of course, this eliminativist view is intuitively unappealing, and to show how statements in ordinary language can in some way be taken to be true, I introduce the normative choice account. According to this view, although non-normative facts about linguistic behavior and about the external world do not determine a precise reference for our terms, our choices may do so. I claim that this provides all that is needed for there to be semantic normativity. First, we are still guided in our choices to some extent by psychological tendencies, and second, there are resources in semantic deliberation to respond to aberrant uses of language. (shrink)

For many years there has been a debate about the role of the parietal lobe in the generation of behavior. Does it generate movement plans (intention) or choose objects in the environment for further processing? To answer this, we focus on the lateral intraparietal area (LIP), an area that has been shown to play independent roles in target selection for saccades and the generation of visual attention. Based on results from a variety of tasks, we propose that LIP acts as (...) a priority map in which objects are represented by activity proportional to their behavioral priority. We present evidence to show that the priority map combines bottom-up inputs like a rapid visual response with an array of top-down signals like a saccade plan. The spatial location representing the peak of the map is used by the oculomotor system to target saccades and by the visual system to guide visual attention. (shrink)

Could emotions be a uniquely human phenomenon? One prominent theory in emotion science, Lisa Feldman Barrett’s Theory of Constructed Emotion (tce), suggests they might be. The source of the sceptical challenge is that tce links emotions to abstract concepts tracking socio-normative expectations, and other animals are unlikely to have such concepts. Barrett’s own response to the sceptical challenge is to relativize emotion to the perspective of an interpreter, but this is unpromising. A more promising response may be to amend the (...) theory, dropping the commitment to the abstract nature of emotion concepts and allowing that, like olfactory concepts, they have disjunctive sensory groundings. Even if other animals were emotionless, this would not imply they lack morally significant interests. Unconceptualized valenced experiences are a sufficient basis for morally significant interests, and such experiences may occur even in the absence of discrete, constructed emotions. (shrink)

Current approaches to formal representation in biomedicine are characterized by their focus on either the static or the dynamic aspects of biological reality. We here outline a theory that combines both perspectives and at the same time tackles the by no means trivial issue of their coherent integration. Our position is that a good ontology must be capable of accounting for reality both synchronically (as it exists at a time) and diachronically (as it unfolds through time), but that these are (...) two quite different tasks, whose simultaneous realization is by no means trivial. The paper is structured as follows. We begin by laying out the methodological and philosophical background of our approach. We then summarize the structure and elements of the Basic Formal Ontology on which it rests, in particular the SNAP ontology of objects and the SPAN ontology of processes. Finally, we apply the general framework to the specific domain of biomedicine. (shrink)

How does consciousness vary across the animal kingdom? Are some animals ‘more conscious’ than others? This article presents a multidimensional framework for understanding interspecies variation in states of consciousness. The framework distinguishes five key dimensions of variation: perceptual richness, evaluative richness, integration at a time, integration across time, and self-consciousness. For each dimension, existing experiments that bear on it are reviewed and future experiments are suggested. By assessing a given species against each dimension, we can construct a consciousness profile for (...) that species. On this framework, there is no single scale along which species can be ranked as more or less conscious. Rather, each species has its own distinctive consciousness profile. (shrink)

According to some philosophers, when introspectively attending to experience, we seem to see right through it to the objects outside, including their properties. This is called the transparency of experience. This paper examines whether, and in what sense, emotions are transparent. It argues that emotional experiences are opaque in a distinctive way: introspective attention to them does not principally reveal non-intentional somatic qualia but rather felt valenced intentional attitudes. As such, emotional experience is attitudinally opaque.

According to some philosophers, the mind enjoys a form of presence to itself. That is to say, in addition to being aware of whatever objects it is aware of, it is also (co-presently) aware of itself. This paper explores the proposal that we should think about this kind of experiential-presence in terms of a form of non-intentional awareness. Various candidates for the relevant form of awareness, as constituting supposed non-intentional experiential-presence, are considered and are shown to encounter significant problems. The (...) fact that a plausible account of the non-intentional awareness which experience putatively has of itself cannot be framed with reference to such forms of awareness is grounds for scepticism concerning the cogency of non-intentional experiential presence.

In this paper, we defend Lucretian Presentism. Although the view faces many objections and has proven unpopular with presentists, we rehabilitate Lucretianism and argue that none of the objections stick.

Those arguing for the existence of non-propositional content appeal to emotions for support, although there has been little engagement in those debates with developments in contemporary theory of emotion, specifically in connection with the kind of mental states that emotional experiences are. Relatedly, within emotion theory, one finds claims that emotional experiences per se have non-propositional content without detailed argument. This paper argues that the content of emotional experience is propositional in a weak sense, associated with aspectual experience and correctness (...) conditions. Furthermore, it provides an interpretation of purely-objectual emotional experiences which satisfies this weak view of propositional content. (shrink)

Jonathan Y. Tsou examines and defends positions on central issues in philosophy of psychiatry. The positions defended assume a naturalistic and realist perspective and are framed against skeptical perspectives on biological psychiatry. Issues addressed include the reality of mental disorders; mechanistic and disease explanations of abnormal behavior; definitions of mental disorder; natural and artificial kinds in psychiatry; biological essentialism and the projectability of psychiatric categories; looping effects and the stability of mental disorders; psychiatric classification; and the validity of the (...) DSM's diagnostic categories. The main argument defended by Tsou is that genuine mental disorders are biological kinds with harmful effects. This argument opposes the dogma that mental disorders are necessarily diseases that result from biological dysfunction. Tsou contends that the broader ideal of biological kinds offers a more promising and empirically ascertainable naturalistic standard for assessing the reality of mental disorders and the validity of psychiatric categories.

In debates about animal sentience, the precautionary principle is often invoked. The idea is that when the evidence of sentience is inconclusive, we should “give the animal the benefit of the doubt” or “err on the side of caution” in formulating animal protection legislation. Yet there remains confusion as to whether it is appropriate to apply the precautionary principle in this context, and, if so, what “applying the precautionary principle” means in practice regarding the burden of proof for animal sentience. (...) Here I construct a version of the precautionary principle tailored to the question of animal sentience together with a practical framework for implementing it. I explain and defend the key features of this framework, argue that it is well-aligned with current practice in animal welfare science, and consider and reject a number of influential counterarguments to the use of precautionary reasoning in this area.

From mitochondria to meerkats, the natural world is full of spectacular examples of social behaviour. In the early 1960s W. D. Hamilton changed the way we think about how such behaviour evolves.

This is a book about the philosophical foundations and future prospects of that program. [Note: only the Introduction (...) is available to download.]. (shrink)

Sentience is the capacity to have feelings, such as feelings of pain, pleasure, hunger, thirst, warmth, joy, comfort and excitement. It is not simply the capacity to feel pain, but feelings of pain, distress or harm, broadly understood, have a special significance for animal welfare law. Drawing on over 300 scientific studies, we evaluate the evidence of sentience in two groups of invertebrate animals: the cephalopod molluscs or, for short, cephalopods (including octopods, squid and cuttlefish) and the decapod crustaceans or, (...) for short, decapods (including crabs, lobsters and crayfish). We also evaluate the potential welfare implications of current commercial practices involving these animals. (shrink)

We are all guided by thousands of norms, but how did our capacity for normative cognition evolve? I propose there is a deep but neglected link between normative cognition and practical skill. In modern humans, complex motor skills and craft skills, such as toolmaking, are guided by internally represented norms of correct performance. Moreover, it is plausible that core components of human normative cognition evolved as a solution to the distinctive problems of transmitting complex motor skills and craft skills, especially (...) skills related to toolmaking, through social learning. If this is correct, the expansion of the normative domain beyond technique to encompass more abstract norms of fairness, reciprocity, ritual and kinship involved the elaboration of a basic platform for the guidance of skilled action by technical norms. This article motivates and defends this “skill hypothesis” for the origin of normative cognition and sets out various ways in which it could be empirically tested. (shrink)

Many philosophers have been attracted to the view that reasons are premises of good reasoning – that reasons to φ are premises of good reasoning towards φ-ing. However, while this reasoning view is indeed attractive, it faces a problem accommodating outweighed reasons. In this article, I argue that the standard solution to this problem is unsuccessful and propose an alternative, which draws on the idea that good patterns of reasoning can be defeasible. I conclude by drawing out implications for the (...) debate over pragmatic reasons for belief and other attitudes and for one influential form of reductionism about the normative. (shrink)

Consciousness has an important role in ethics: when a being consciously experiences the frustration or satisfaction of its interests, those interests deserve higher moral priority than those of a behaviourally similar but non-conscious being. I consider the relationship between this ethical role and an a posteriori (or “type-B”) materialist solution to the mind-body problem. It is hard to avoid the conclusion that, if type-B materialism is correct, then the reference of the concept of phenomenal consciousness is radically indeterminate between a (...) neuronal-level property that is distinctive to mammals and a high-level functional property that is much more widely shared. This would leave many non-mammalian animals (such as birds, fish, insects and octopuses) with indeterminate moral status. There are ways to manage this radical moral indeterminacy, but all of these ways lead to profoundly troubling consequences. (shrink)

Epistemic Courage is a timely and thought-provoking exploration of the ethics of belief, which shows why epistemology is no mere academic abstraction - the question of what to believe couldn't be more urgent. Jonathan Ichikawa argues that a skeptical, negative bias about belief is connected to a conservative bias that reinforces the status quo.
