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)

How should we understand good philosophical inquiry? Ernest Sosa has argued that the key to answering this question lies with virtue-based epistemology. According to virtue-based epistemology, competences are prior to epistemic justification. More precisely, a subject is justified in having some type of belief only because she could have a belief of that type by exercising her competences. Virtue epistemology is well positioned to explain why, in forming false philosophical beliefs, agents are often less rational than it is possible to (...) be. False philosophical beliefs are often unjustified—and the agent is thereby less rational for having them—precisely because these beliefs could not be formed by exercising competences. But, virtue epistemology is not well positioned to explain why, in failing to form some true philosophical beliefs, agents are less rational than it is possible to be. In cases where agents fall short by failing to believe philosophical truths, the problem is not that they believe things they shouldn’t, but that they lack beliefs they ought to have. We argue that Timothy Williamson's recent critique of the a priori/a posteriori distinction falls prey to similar problem cases. Williamson fails to see that a type of belief might be a priori justified if and only if, even without any special confirming experiences, agents fall short by failing to have this type of belief. We conclude that there are types of beliefs that are deeply a priori justified for any agent regardless of what epistemic competences the agent has. However, we also point out that this view has a problem of its own: it appears to make the acquisition of a priori knowledge too easy. We end by suggesting that a move back towards virtue-based epistemology is necessary. But in order for this move to be effective, epistemic competences will have to be understood very differently than in the reliabilist tradition. (shrink)

Cooperation is rife in the microbial world, yet our best current theories of the evolution of cooperation were developed with multicellular animals in mind. Hamilton’s theory of inclusive fitness is an important case in point: applying the theory in a microbial setting is far from straightforward, as social evolution in microbes has a number of distinctive features that the theory was never intended to capture. In this article, I focus on the conceptual challenges posed by the project of extending Hamilton’s (...) theory to accommodate the effects of gene mobility. I begin by outlining the basics of the theory of inclusive fitness, emphasizing the role that the concept of relatedness is intended to play. I then provide a brief history of this concept, showing how, over the past fifty years, it has departed from the intuitive notion of genealogical kinship to encompass a range of generalized measures of genetic similarity. I proceed to argue that gene mobility forces a further revision of the concept. The reason in short is that, when the genes implicated in producing social behaviour are mobile, we cannot talk of an organism’s genotype simpliciter; we can talk only of an organism’s genotype at a particular stage in its life cycle. We must therefore ask: with respect to which stage(s) in the life cycle should relatedness be evaluated? For instance: is it genetic similarity at the time of social interaction that matters to the evolution of social behaviour, or is it genetic similarity at the time of reproduction? I argue that, strictly speaking, it is neither of these: what really matters to the evolution of social behaviour is diachronic genetic similarity between the producers of fitness benefits at the time they produce them and the recipients of those benefits at the end of their life-cycle. I close by discussing the implications of this result. The main payoff is that it makes room for a possible new mechanism for the evolution of altruism in microbes that does not require correlated interaction among bearers of the genes for altruism. The importance of this mechanism in nature remains an open empirical question. (shrink)

Recent developments in experimental philosophy (‘x-phi’) suggest that there is a new way in which the empirical and normative dimensions of bioethics can be brought into successful dialogue with one another. It revolves around conceptual analysis – though not the kind of conceptual analysis one might perform in an armchair. Following Édouard Machery, this is Conceptual Analysis Rebooted. In short, morally-pertinent medical concepts like ‘treatment’, ‘euthanasia’ and ‘sanctity of life’ can each have several meanings that underwrite inferences with different (...) moral implications. X-phi shows us that an experimental approach to conceptual analysis can make explicit the implicit structures that underpin our thinking about such concepts. By presenting concrete examples, I aim to offer a glimpse of an empirically-grounded, practically-normative 'bioxphi' that demystifies and distinguishes medical concepts, assesses the normative inferences these concepts dispose us to draw and revises those inferences that are deficient.

Intuitively, collective nouns are pseudo-singular: a collection of things (a pair of people, a flock of birds, etc.) just is the things that make ‘it’ up. But certain facts about natural language seem to count against this view. In short, distributive predicates and numerals interact with collective nouns in ways that they seemingly shouldn’t if those nouns are pseudo-singular. We call this set of issues ‘the distribution problem’. To solve it, we propose a modification to cover-based semantics. On this (...) semantics, the interpretation of distributive predicates and numerals depends on a cover, where the choice of cover is strongly semantically constrained by the noun with which they interact.

Suppose that, while you are dreamlessly asleep, the sizes of and distances between all objects in the world are uniformly multiplied. Would you be able to detect this global inflation? Intuitively, no. But would your experience of size remain accurate? Intuitively, yes. On these grounds, some have concluded that our experiences do not represent size and instead represent modes of presentation of size. We are, in this sense, ‘cut off’ from the sizes of things in the external world. Here, I (...) argue for a more modest conclusion: undetectable inflation reveals that our experiences represent only relative size. Call this view austere phenomenal relativism––or austere relativism, for short. I develop a framework to contrast austere relativism with its competitors, give an extended argument for the view, and then defuse a potential dilemma concerning the units in which our experiences represent size.

Deep Brain Stimulation is currently being investigated as an experimental treatment for patients suffering from treatment-refractory AN, with an increasing number of case reports and small-scale trials published. Although still at an exploratory and experimental stage, initial results have been promising. Despite the risks associated with an invasive neurosurgical procedure and the long-term implantation of a foreign body, DBS has a number of advantageous features for patients with SE-AN. Stimulation can be fine-tuned to the specific needs of the particular patient, (...) is relatively reversible, and the technique also allows for the crucial issue of investigating and comparing the effects of different neural targets. However, at a time when DBS is emerging as a promising investigational treatment modality for AN, lesioning procedures in psychiatry are having a renaissance. Of concern it has been argued that the two kinds of interventions should instead be understood as rivaling, yet “mutually enriching paradigms” despite the fact that lesioning the brain is irreversible and there is no evidence base for an effective target in AN. We argue that lesioning procedures in AN are unethical at this stage of knowledge and seriously problematic for this patient group, for whom self-control is particularly central to wellbeing. They pose a greater risk of major harms that cannot justify ethical equipoise, despite the apparent superiority in reduced short term surgical harms and lower cost. (shrink)

While many have argued that moral disagreement poses a challenge to moral knowledge, the precise nature of this challenge is controversial. Indeed, in the moral epistemology literature, there are many different versions of ‘the’ argument from moral disagreement to moral scepticism. This paper contributes to this vast literature on moral disagreement by arguing for two theses: 1. All (or nearly all) moral disagreement arguments share an underlying structure; and, 2. All moral disagreement arguments that satisfy this underlying structure cannot establish (...) moral scepticism because this underlying structure leads to a previously unrecognized reductio ad absurdum. In short, I argue that this reductio argument (very likely) refutes all versions of the moral disagreement to moral scepticism argument in one fell swoop. (shrink)

A reply to commentators -- Jake Beck, Nico Orlandi and Aaron Franklin, and Ian Phillips -- on our paper "Does perceptual consciousness overflow cognitive access?".

This is a short introductory article. I focus on three questions: What is instrumental rationality? What are the principles of instrumental rationality? Could instrumental rationality be all of practical rationality?

In “The Possibility of Epistemic Nudging” (2021), Thomas Grundmann examines nudging as applied to doxastic attitudes. Grundmann argues that given the right presuppositions about knowledge, justified beliefs, and the relevant belief-forming processes, doxastic nudging can result in justified beliefs and even knowledge in the nudgee. In this short response we will raise some critical concerns for Grundmann’s project as well as open up a path for epistemic nudges (nudges that result in justified beliefs or knowledge) that Grundmann too quickly (...) dismisses.

Michael Rose’s Zukünftige Generationen in der heutigen Demokratie: Theorie und Praxis der Proxy-Repräsentation (Future Generations in Today’s Democracy: Theory and Practice of Proxy Representation) is an ambitious and fascinating work. It provides a new conceptualisation of the representation of future generations and it also delivers the most extensive empirical study of institutions for the representation of future generations available to date. The book is based on Rose’s PhD thesis at the Heinrich Heine University, Düsseldorf, Germany, and is 516 pages long (...) (excluding an extensive bibliography, list of sources and appendices). A third of the thesis is devoted to short case studies of a total of 29 institutions which are presented in a catalogue format, allowing this section to be used as an encyclopaedia. The book is written concisely and is well documented throughout. (shrink)

It is a matter of philosophical debate whether Jonathan Israel’s assessment of Spinoza’s notion of ‘state religion’ can be interpreted as an atheistic and Marxist reading of Spinoza. Contrary to the widely accepted view, Spinoza has a peculiar understanding of religion; and thus, his views cannot, simply, be equated with atheism. By relying on this fact, in this article, I am going to shed light on the issue and try to show to what extent Israel’s interpretation goes beyond what (...) Spinoza himself claims and whether or not Spinoza’s views can make him an atheist. Another concern of the text will be elucidating Marx’s critique of Bruno Bauer’s argument for the abolition of religion and laying bare if there is any continuity between Marx and Spinoza on the problem of religion. After Israel’s interpretation is restated, both Spinozistic view of religion, as he puts forward in the Theological-Political Treatise [Tractatus Theologico- Politicus, 1670] and Political Treatise [Tractatus Politicus, 1676] and Marx’s arguments on the same issue in “On the Jewish Question” [in Deutsch-Franzosische Jahrbucher, 1844] will be examined in detail. Depending on these investigations, it will be argued that what Israel defends in his text Radical Enlightenment [2001] does not make Spinoza an atheist; on the contrary, although Spinoza is not an advocate of the commonsensical view of religion, he defends his own understanding of religion—which causes him to be regarded, prejudicedly, as an atheist. Furthermore, it will be pointed out that Israel’s interpretation cannot be a Marxist interpretation either because Marx’s critique of religion is generally misunderstood and mistaken with that of Bruno Bauer. Neither Spinoza’s views on religion nor that of Marx are completely compatible with what Israel defends in Radical Enlightenment; nevertheless, this does not mean that Israel tries to make an atheist or Marxist out of Spinoza through his appropriation of the philosopher.

Short‐term memory in vision is typically thought to divide into at least two memory stores: a short, fragile, high‐capacity store known as iconic memory, and a longer, durable, capacity‐limited store known as visual working memory (VWM). This paper argues that iconic memory stores icons, i.e., image‐like perceptual representations. The iconicity of iconic memory has significant consequences for understanding consciousness, nonconceptual content, and the perception–cognition border. Steven Gross and Jonathan Flombaum have recently challenged the division between iconic memory (...) and VWM by arguing against the idea of capacity limits in favor of a flexible resource‐based model of short‐term memory. I argue that, while VWM capacity is probably governed by flexible resources rather than a sharp limit, the two memory stores should still be distinguished by their representational formats. Iconic memory stores icons, while VWM stores discursive (i.e., language‐like) representations. I conclude by arguing that this format‐based distinction between memory stores entails that prominent views about consciousness and the perception–cognition border will likely have to be revised.

Jonathan Jenkins Ichikawa has presented a series of examples that are meant to spell trouble for Presuppositional Epistemic Contextualism. In this short article I aim to establish two things. First, I argue that even if Ichikawa’s examples were viable counterexamples to PEC, they would not threaten the key ideas underlying the account in my 2009 article ‘Knowledge and Presuppositions’. The philosophically interesting work that is done in that article remains unaffected by Ichikawa’s alleged counterexamples. In the second part (...) of the paper, I argue that the examples are not in fact successful counterexamples to PEC. The data emerging from Ichikawa’s examples can be accounted for within the framework of PEC. (shrink)

The Emotions chapter (XXV) in James' Principles of Psychology traverses the entire range of experienced emotions from the “coarser” and more instinctual to the “subtler” emotions intimately involved in cognitive, moral, and aesthetic aspects of life. But Principles limits himself to an account of emotional consciousness and so there are few direct discussions in the text of Principles about what later came to be called moral psychology, and fewer about anything resembling philosophical ethics. Still, James’ short section on the (...) subtler emotions, when read in connection with his later philosophical writings, still provides insight on James’ views about how human emotion colors our moral psychology and agency. The paper tries to articulate how James' somatic account of emotion adds significantly to contemporary discussions at the borders of moral psychology and philosophy: discussions over the foreground/background distinction, emotional temperament, emotional learning, moral imagination, and selfhood and narrativity. The final section focuses on the neo-Jamesian character of "new sentimentalist" moral psychologists. Among the substantial connections I discuss between James and 1) between Jonathan Haidt’s “social intuitionism” and 2) Jesse Prinz’s "emotionism" are the critiques that they each share of the pretensions of hard universalist ethical theories.

In a widely read essay, “For the Law, Neuroscience Changes Nothing and Everything,” Joshua Greene and Jonathan Cohen argue that the advance of neuroscience will result in the widespread rejection of free will, and with it – of retributivism. They go on to propose that consequentialist reforms are in order, and they predict such reforms will take place. We agree that retributivism should be rejected, and we too are optimistic that rejected it will be. But we don’t think that (...) such a development will have much to do with neuroscience – it won’t, because neuroscience is unlikely to show that we have no free will. We have two main aims in this paper. The first is to rebut various aspects of the case against free will. The second is to examine the case for consequentialist reforms. We take Greene and Cohen’s essay as a hobbyhorse, but our criticisms are applicable to neurodeterministic anti-free-willism in general. We first suggest that Greene and Cohen take proponents of free will to be committed to an untenable homuncular account of agency. But proponents of free will can dispense with such a commitment. In fact, we argue, it is Greene and Cohen who work with an overly simple account of free will. We sketch a more nuanced conception. We then turn to the proposal for consequentialist reforms. We argue that retributivism will fall out of favor not as a consequence of neuroscience-driven rejection of free will, but rather, as a result of a familiar feature of moral progress – the expanding circle of concern. In short, retributivism can and must die, but neuroscience will not kill it – humanity will. (shrink)

This dissertation answers the three value problems in epistemology. These three problems require an answer as to how knowledge is more valuable 1) than mere true belief, 2) any of the proper subsets of knowledge, and 3) in kind than that which falls short of knowledge. The methodology used to provide an answer to these problems relies on the arguments put forth in a rarely discussed paper from Ward Jones. In short, the Jonesian approach can be summed up (...) as the view that epistemic axiology and analysis ought to be kept separate. The Jonesian framework instead looks outside of the necessary and sufficient conditions of knowledge to find properties of knowledge which, though contingent, can explain the distinctive value of knowledge. Thisframework, though remarkably robust, requires going against what I consider to be the orthodox approach to the problems. This orthodox approach relies on two axiological assumptions. The first is that every component of an analysis on knowledge must provide independent value to knowledge. The second assumption is that the value of knowledge cannot be derived from factors excluded from an analysis of knowledge. Once these assumptions are appropriately discarded, the Jonesian view has a straightforward answer to the first problem. Answering the second requires assessing Jonathan Kvanvig’s claim that a satisfied Gettier condition contributes no independent value. While I agree with Kvanvig regarding a satisfied Gettier condition, I will argue that an unsatisfied Gettier condition is not likewise neutral; it contributes disvalue. With that distinction in place, a solution to the second problem follows immediately. The third value problem, however, is a different kind of problem altogether. Answering it requires not only the Jonesian framework, but also a novel account of how we determine final value. Once this account is offered, a Jonesian answer to the tertiary problem follows immediately. This dissertation closes by applying the Jonesian framework to an argument that claims there can be no modal conditions on knowledge due to such conditions failing to help answer the value problems. This claim will be found wanting. (shrink)

What faculty of our mind is best suited to endow us with all that is required to carry forth our moral enterprise? In other words, what are the cognitive resources that subserve the moral mind? This is a core empirical question, raised much to the delight of the investigative inquisitiveness of the moral psychologists. But the philosophical connection to this problem can be traced back to as far in time as that of Plato the main tenet of whose tripartite theory (...) of soul was that the rational element of the soul is like the charioteer who holds sway over his two horses – the manageable one, i.e. the spirited element and the unwieldy one, i.e. the vegetative, emotionally unruly element of the soul. And the era of reasonemotion debate begins, percolating into the field of moral beliefs that we inculcate and judgments that we pronounce. The mainstay of this short paper is a comparative analysis of two recently emerging theoretical frameworks claimed to be underlying moral judgments – one espoused by moral psychologist Jonathan Haidt claims that moral judgment is primarily elicited unconsciously by affectdriven intuition and the other put forward by philosopher Shaun Nichols attempts to highlight the conscious deliberation about moral rules. After critical analysis of both the views, this work suggests that a syncretic approach to the aetiological theorization about moral judgment may provide some silver lining. (shrink)

In this paper, we shall describe and critically evaluate four contemporary theories which attempt to solve the problem of the infinite regress of reasons: BonJour's ‘impure’ coherentism, BonJour's foundationalism, Haack's ‘foundherentism’ and Dancy's pure coherentism. These theories are initially put forward as theories about the justification of our empirical beliefs; however, in fact they also attempt to provide a successful response to the question of their own ‘metajustification.’ Yet, it will be argued that 1) none of the examined theories is (...) successful as a theory of justification of our empirical beliefs, and that 2) they also fall short of being adequate theories of metajustification. It will be further suggested that the failure of these views on justification is not coincidental, but is actually a consequence of deeper and tacitly held problematic epistemological assumptions (namely, the requirements of justificatory generality and epistemic priority), whose acceptance paves the way towards a generalized scepticism about empirical justification.

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.

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)

Critical notice of Christoph Kelp and Mona Simion's _Sharing Knowledge: A Functionalist Account of Assertion_.

A number of writers have drawn on Hayek’s epistemic defence of market institutions to argue that free-markets and tort law are best placed to overcome the knowledge problems associated with the environmental sphere. This paper argues to the contrary, that this Austrian School approach itself suffers from significant knowledge problems. The first of these relates to the ability of Austrian economics to assign victim compensation and the second to the difficulty of establishing causation in complex environmental problems. The paper will (...) also show how alternative approaches may not suffer from these epistemic challenges and are better placed to overcome them. (shrink)

Epistemic questions have become an important area of debate within democratic theory. Epistemic democrats have revived epistemic justification of democracy, while social scientific research has speared a significant debate on voter knowledge. An area which has received less attention, however, is the epistemic case for markets. Market advocates have developed a number of epistemic critiques of democracy which suggest that most goods are better provided by markets than democratic institutions. Despite representing important challenges to democracy, these critiques have gone without (...) reply as democratic theorists have tended to exclude markets from consideration. This article responds to these critiques and argues that there are good epistemic grounds for granting a much greater role to democracy than its market critics have claimed. It argues that there is a broad range of goods, including important ethical goods, which are better provided by democracy than markets due to the particular epistemic burdens they create. (shrink)

Political polarization is one of the most discussed challenges facing contemporary democracies and is often associated with a broader epistemic crisis. While inspiring a large literature in political science, polarization’s epistemic problems also have significance for normative democratic theory, and this study develops a new approach aimed at understanding them. In contrast to prominent accounts from political psychology—group polarization theory and cultural cognition theory—which argue that polarization leads individuals to form unreliable political beliefs, this study focuses on system-level diversity. It (...) argues that polarization’s epistemic harms are best located in its tendency to reduce the diversity of perspectives utilized in a democratic system and in how this weakens the system’s ability to identify and address problems of public concern. Understanding such harms is also argued to require a greater consideration of the political dynamics of polarization and issues of elite discourse, alongside political psychology. (shrink)

This chapter examines the history of philosophy of psychology and philosophy of psychiatry as subfields of philosophy of science that emerged in the late twentieth and early twenty-first century. The chapter also surveys related literatures that developed in psychology and psychiatry. Philosophy of psychology (or philosophy of cognitive science) has been a well-established subfield of philosophy of mind since the 1990s and 2000s. This field of philosophy of psychology is narrowly focused on issues in cognitive psychology and cognitive science. Compared (...) to the thriving subfield of philosophy of cognitive science, there has been a lack of corresponding interest among philosophers of science in broader methodological questions about different paradigms and fields of study in psychology. These broader methodological questions about psychology have been addressed in the field of theoretical psychology, which is a subfield of psychology that materialized in the 1980s and 1990s. Philosophy of psychiatry emerged as a subfield of philosophy of science in the mid-2000s. Compared to philosophy of psychology, the philosophy of psychiatry literature in philosophy of science engaged with issues examined in an older and more interdisciplinary tradition of philosophy of psychiatry that developed after the 1960s. The participation of philosophers of science in the literature on theoretical psychology, by contrast, has been limited. (shrink)

A crux of Plato’s Symposium is how beauty relates to the good. Diotima distinguishes beauty from the good, I show, to explain how erotic pursuits are characteristically ambivalent and opaque. Human beings pursue beauty without knowing why or thinking it good; yet they are rational, if aiming at happiness. Central to this reconstruction is a passage widely taken to show that beauty either coincides with the good or demands disinterested admiration. It shows rather that what one loves as beautiful does (...) not appear good, a proposal with ramifications for ethical psychology. (shrink)

Conciliationism is the family of views that rationality requires agents to reduce confidence or suspend belief in p when acknowledged epistemic peers (i.e. agents who are (approximately) equally well-informed and intellectually capable) disagree about p. While Conciliationism is prima facie plausible, some have argued that Conciliationism is not an adequate theory of peer disagreement because it is self-undermining. Responses to this challenge can be put into two mutually exclusive and exhaustive groups: the Solution Responses which deny Conciliationism is self-undermining and (...) attempt to provide arguments which demonstrate this; and the Skeptical Responses which accept that Conciliationism is self-undermining but attempt to mitigate this result by arguing this is either impermanent and/or not very worrisome. I argue that, by Conciliationism’s own lights, both kinds of responses (almost certainly) fail to save Conciliationism from being self-undermining. Thus, Conciliationism is (almost certainly) permanently self-undermining. This result is significant because it demonstrates that Conciliationism is likely hopeless: there is likely nothing that can save Conciliationism from this challenge. I further argue that Conciliationism, like any view, should be abandoned if it is (almost certainly) hopeless. (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.

For several decades scientists and philosophers studying how the mind works have debated the issue of modularity. Their main disagreements concern the massive modularity hypothesis, according to which all (or most) of our cognitive mechanisms are modular in nature. Pietraszewski and Wertz (2022) have recently suggested that the modularity debate is based on a confusion about the levels of analysis at which the mind can be explained. This article argues that their position suffers from three major problems: (1) the argument (...) is unsound, with untrue premises; (2) it glosses over important empirical issues; and (3) the guidelines it offers are not sufficient for avoiding future confusions. As these criticisms are developed, this article will provide a way of making sense of the modularity debate—with an eye for what really is at stake both conceptually and empirically—and, by identifying a false assumption often shared by proponents and opponents of the massive modularity hypothesis alike, it will sketch out some guidelines for moving the debate forward.

Using two decades worth of experimental philosophy (aka x-phi), Edouard Machery argues in Philosophy within its Proper Bounds (OUP, 2017) that philosophers’ use of the “method of cases” is unreliable because it has a strong tendency to elicit different intuitive responses from non-philosophers. And because, as Machery argues, appealing to such cases is usually the only way for philosophers to acquire the kind of knowledge they seek, an extensive philosophical skepticism follows. I argue that Machery’s “Unreliability” argument fails because, once (...) its premises are percisified, they are either self-defeating or without justification. This is a significant result because Machery’s arguments are the most widely cited and discussed x-phi arguments for philosophical skepticism and many hold that Machery provides the most empirically informed, convincing, and thus best case for this kind of skepticism. So, if my arguments are sound, then the best x-phi argument for philosophical skepticism fails. I further argue that this result provides strong reason to believe the more general conclusion that “negative” x-phi is likely doomed: x-phi likely can never support a substantive philosophical skepticism. Ultimately, I argue for the broad conclusion that all empirically minded arguments for philosophical skepticism are likely to fail for the same reasons that Machery’s does, i.e. they are (likely) self-defeating.

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 an intriguing though somewhat enigmatic line of thought first proposed by Jonathan Bennett, if humanity went extinct any time soon this would be unfortunate because important business would be left unfinished. This line of thought remains largely unexplored. I offer an interpretation of the idea that captures its intuitive appeal, is consistent with plausible constraints, and makes it non-redundant to other views in the literature. The resulting view contrasts with a welfare-promotion perspective, according to which extinction would (...) be bad because it would come at a massive opportunity cost in terms of feasibly achievable welfare over the lifetime of our species.

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)

Can octopuses feel pain and pleasure? What about crabs, shrimps, insects, or spiders? How do we tell whether a person unresponsive after severe brain injury might be suffering? When does a fetus in the womb start to have conscious experiences? Could there even be rudimentary feelings in miniature models of the human brain, grown from human stem cells? And what about AI? These are questions about the edge of sentience, and they are subject to enormous, disorienting uncertainty. The stakes are (...) immense, and neglecting the risks can have terrible costs. We need to err on the side of caution, yet it’s often far from clear what ‘erring on the side of caution’ should mean in practice. When are we going too far? When are we not doing enough? The Edge of Sentience presents a comprehensive precautionary framework designed to help us reach ethically sound, evidence-based decisions despite our uncertainty. (shrink)

Abstract: In The Imaginary Jean-Paul Sartre makes what will strike many as an implausibly strong claim, namely that perception and imagination are incompatible kinds of experience - I call this the exclusion claim. This paper offers a reconstruction of Sartre’s exclusion claim. First, it frames the claim in terms of cross-modal attention distribution, such that it is not possible to simultaneously attend to what one is imagining and what one is perceiving. However, this leaves it open that a subject can (...) simultaneously imagine and perceive on the condition that either the perceived or imagined objects are not attended to. While this is a philosophically plausible position it fails to do justice to Sartre’s intended position, which suggests a more radical exclusion between perception and imagination. In light of this section 3 develops a supplementary argument to remove one of the possible configurations of attention that the ban on divided attention leaves in place by arguing that the objects of imagining must be attended to, which follows from Sartre’s characterisation of imagination as spontaneous. The resulting exclusion is as follows: attentive perception excludes imagination (and vice versa), given that the latter is necessarily attentive, but attentive imagination can co-occur with non-attentive or background perception (in this sense the exclusion is asymmetric in a way that Sartre fails to recognise). In concluding I detail how from this exclusion we get an important consequence – which Sartre wants the exclusion claim to have – namely that it rules out an imagination-based solution to the problem of perceptual presence.

There are two central kinds of epistemological mistakes: believing things you shouldn’t, and failing to believe things that you should. The knowledge-first program offers a canonical explanation for the former: if you believe something without knowing it, you violate the norm to believe only that which you know. But the explanation does not extend in any plausible way to a story about what’s wrong with suspending judgment when one ought to believe. In this paper I explore prospects for a knowledge-centering (...) account of positive epistemic norms that describe epistemic duties to believe. (shrink)

It would be unwise to dismiss the possibility of human brain organoids developing sentience. However, scepticism about this idea is appropriate when considering current organoids. It is a point of consensus that a brain-dead human is not sentient, and current organoids lack a functioning brainstem. There are nonetheless troubling early warning signs, suggesting organoid research may create forms of sentience in the near future. To err on the side of caution, researchers with very different views about the neural basis of (...) sentience should unite behind the “brainstem rule”: if a neural organoid develops or innervates a functioning brainstem that regulates arousal and leads to sleep-wake cycles, then it is a sentience candidate. If organoid research leads to the creation of sentience candidates, a moratorium or indefinite ban on the creation of the relevant type of organoid may be appropriate. A different way forward, more consistent with existing approaches to animal research, would be to require ethical review and harm-benefit analysis for all research on sentience candidates. (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)

Recently, more attention has been paid to the nature and value of the intellectual virtue of epistemic autonomy. One underexplored issue concerns how epistemic autonomy is related to other intellectual virtues. Plausibly, epistemic autonomy is closely related to a number of intellectual virtues like curiosity, inquisitiveness, intellectual perseverance, and intellectual courage to name just a few. Here, however, I will examine the relation between epistemic autonomy and intellectual humility. I will argue that epistemic autonomy and intellectual humility bear an interesting (...) relationship to one another in that they are interconnected and mutually supporting intellectual virtues. In sections 2 and 3 I will provide a brief overview of the predominant accounts of intellectual humility (section 2) and epistemic autonomy (section 3) in the literature. With an understanding of these intellectual virtues in hand, we will examine their relationship of mutual support in section 4. Section 5 will explore a challenge to this relationship coming from the epistemology of disagreement, and section 6 concludes. (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)

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.

Human neural organoid research is advancing rapidly. As Greely notes in the target article, this progress presents an “onrushing ethical dilemma.” We can’t rule out the possibility that suff...

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. He introduced three key innovations - now known as Hamilton's rule, kin selection, and inclusive fitness - and his pioneering work kick-started a research program now known as social evolution theory. This is a book about the philosophical foundations and future prospects of that program. [Note: only the Introduction (...) is available to download.]. (shrink)

In an intriguing essay, G. A. Cohen has defended a conservative bias in favour of existing value. In this paper, we consider whether Cohen’s conservatism raises a new challenge to the use of human enhancement technologies. We develop some of Cohen’s suggestive remarks into a new line of argument against human enhancement that, we believe, is in several ways superior to existing objections. However, we shall argue that on closer inspection, Cohen’s conservatism fails to offer grounds for a strong sweeping (...) objection to enhancement, and may even offer positive support for forms of enhancement that preserve valuable features of human beings. Nevertheless, we concede that Cohen’s arguments may suggest some plausible and important constraints on the modality of legitimate and desirable enhancements. (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)
