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.

There is no agreement on whether any invertebrates are conscious and no agreement on a methodology that could settle the issue. How can the debate move forward? I distinguish three broad types of approach: theory-heavy, theory-neutral and theory-light. Theory-heavy and theory-neutral approaches face serious problems, motivating a middle path: the theory-light approach. At the core of the theory-light approach is a minimal commitment about the relation between phenomenal consciousness and cognition that is compatible with many specific theories of consciousness: the (...) hypothesis that phenomenally conscious perception of a stimulus facilitates, relative to unconscious perception, a cluster of cognitive abilities in relation to that stimulus. This “facilitation hypothesis” can productively guide inquiry into invertebrate consciousness. What is needed? At this stage, not more theory, and not more undirected data gathering. What is needed is a systematic search for consciousness-linked cognitive abilities, their relationships to each other, and their sensitivity to masking. (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.

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)

When two agents engage in a joint action, such as rowing together, they exercise joint know-how. But what is the relationship between the joint know-how of the two agents and the know-how each agent possesses individually? I construct an “active mutual enablement” account of this relationship, according to which joint know-how arises when each agent knows how to predict, monitor, and make failure-averting adjustments in response to the behaviour of the other agent, while actively enabling the other to make such (...) adjustments. I defend the AME account from three objections, and I then use this account as the platform for an examination of the reducibility of joint know-how to joint propositional knowledge. A summative account of joint propositional knowledge is incompatible with the reduction of joint know-how to joint propositional knowledge, whereas a distributive account is not. I close by highlighting some open questions the AME account brings into view concerning the evolutionary origin and scaling up of joint know-how. (shrink)

Emotion theory includes attempts to reduce or assimilate emotions to states such as bodily feelings, beliefs-desire combinations, and evaluative judgements. Resistance to such approaches is motivated by the claim that emotions possess a sui generis phenomenology. Uriah Kriegel defends a new form of emotion reductivism which avoids positing irreducible emotional phenomenology by specifying emotions’ phenomenal character in terms of a combination of other phenomenologies. This article argues Kriegel’s approach, and similar proposals, are unsuccessful, since typical emotional experiences are constituted by (...) sui generis feelings towards value. (shrink)

Peter Carruthers has recently argued for a surprising conditional: if a global workspace theory of phenomenal consciousness is both correct and fully reductive, then there are no substantive facts to discover about phenomenal consciousness in nonhuman animals. I present two problems for this conditional. First, it rests on an odd double-standard about the ordinary concept of phenomenal consciousness: its intuitive non-gradability is taken to be unchallengeable by future scientific developments, whereas its intuitive determinacy is predicted to fall by the wayside. (...) Second, it relies on dismissing, prematurely, the live empirical possibility that phenomenal consciousness may be linked to a core global broadcast mechanism that is shared by a wide range of animals. Future developments in the science of consciousness may lead us to reconsider the non-gradability of phenomenal consciousness, but they are unlikely to lead us to accept that there are no facts to discover outside the paradigm case of a healthy adult human.

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)

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)

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)

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)

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)

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)

This is a response to the nine commentaries on our target article “Unlimited Associative Learning: A primer and some predictions”. Our responses are organized by theme rather than by author. We present a minimal functional architecture for Unlimited Associative Learning that aims to tie to together the list of capacities presented in the target article. We explain why we discount higher-order thought theories of consciousness. We respond to the criticism that we have overplayed the importance of learning and underplayed the (...) importance of spatial modelling. We decline the invitation to add a negative marker to our proposed positive marker so as to rule out consciousness in plants, but we nonetheless maintain that there is no positive evidence of consciousness in plants. We close by discussing how UAL relates to development and to its material substrate. (shrink)

Altruistic deception (or the telling of “white lies”) is common in humans. Does it also exist in non-human animals? On some definitions of deception, altruistic deception is impossible by definition, whereas others make it too easy by counting useful-but-ambiguous information as deceptive. I argue for a definition that makes altruistic deception possible in principle without trivializing it. On my proposal, deception requires the strategic exploitation of a receiver by a sender, where “exploitation” implies that the sender elicits a behaviour in (...) the receiver that is beneficial in a different type of situation and is expressed only because the signal raises the probability, from the receiver’s standpoint, of that type of situation. I then offer an example of a real signal that is deceptive in this sense, and yet potentially altruistic (and certainly cooperative): the purr call of the pied babbler. Fledglings associate purr calls with food, and adults exploit this learned association, in the absence of food, to lead fledglings away from predators following an alarm call. I conclude by considering why altruistic deception is apparently so rare in non-human animals. (shrink)

Jurgen Habermas has argued that carrying out pre-natal germline enhancements would be inimical to the future child's autonomy. In this article, I suggest that many of the objections that have been made against Habermas' arguments by liberals in the enhancement debate misconstrue his claims. To explain why, I begin by explaining how Habermas' view of personal autonomy confers particular importance to the agent's embodiment and social environment. In view of this, I explain that it is possible to draw two arguments (...) against germline enhancements from Habermas' thought. I call these arguments ‘the argument from negative freedom’ and ‘the argument from natality’. Although I argue that many of the common liberal objections to Habermas are not applicable when his arguments are properly understood, I go on to suggest ways in which supporters of enhancement might appropriately respond to Habermas' arguments.

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.

Over the past two decades, Ginsburg and Jablonka have developed a novel approach to studying the evolutionary origins of consciousness: the Unlimited Associative Learning framework. The central idea is that there is a distinctive type of learning that can serve as a transition marker for the evolutionary transition from non-conscious to conscious life. The goal of this paper is to stimulate discussion of the framework by providing a primer on its key claims and a clear statement of its main empirical (...) predictions. (shrink)

I briefly present and motivate a ‘skill hypothesis’ regarding the evolution of human normative cognition. On this hypothesis, the capacity to internally represent action-guiding norms evolved as a solution to the distinctive problems of standardizing, learning and teaching complex motor skills and craft skills, especially skills related to toolmaking. We have an evolved cognitive architecture for internalizing norms of technique, which was then co-opted for a rich array of social functions. There was a gradual expansion of the normative domain, with (...) ritual playing an important role in bridging the gap between concrete, enacted norms and general, abstract norms, such as kinship norms. I conclude by stating nine predictions arising from the skill hypothesis. (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.

This paper attempts to reconcile critics and defenders of inclusive fitness by constructing a synthesis that does justice to the insights of both. I argue that criticisms of the regression-based version of Hamilton’s rule, although they undermine its use for predictive purposes, do not undermine its use as an organizing framework for social evolution research. I argue that the assumptions underlying the concept of inclusive fitness, conceived as a causal property of an individual organism, are unlikely to be exactly true (...) in real populations, but they are approximately true given a specific type of weak selection that Hamilton took, on independent grounds, to be responsible for the cumulative assembly of complex adaptation. Finally, I reflect on the uses and limitations of “design thinking” in social evolution research. The debate about the foundations of inclusive fitness theory that has followed in the wake of Nowak, Tarnita and Wilson’s (1) critique has been remarkably polarizing. After several rounds of rebuttals and replies, there is still little evidence of any serious reconciliation between the theory’s critics (2-10) and its defenders (11-24). It doesn’t have to be this way. I believe that, on the main points of disagreement, it is possible to find a way forward that does justice to the insights of both camps. My aim in this paper is to find that way forward. (shrink)

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)

This article gives an overview of some recent debates about the relationship between reasons and rational requirements of coherence - e.g. the requirements to be consistent in our beliefs and intentions, and to intend what we take to be the necessary means to our ends.

This chapter surveys a few of the central questions about philosophical perspectives on the ethics of belief, focusing especially on (1) questions about whether doxastic involuntarism is consistent with the normative approach to epistemology characteristic of any ethics of belief; (2) the status and interpretation of William Clifford's famous injunction against belief on "insufficient" evidence, and broader questions about the role of negative versus positive doxastic norms; (3) whether norms governing belief are distinctively epistemic norms, or are instead moral or (...) practical ones; and (4) how moral and political questions about belief bear on epistemic norms, including a discussion of doxastic wronging, racist beliefs, skepticism and rape culture, and epistemic partiality—whether, for instance, friendship requires beliefs that violate epistemic norms.

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.

What makes fast, cumulative cultural evolution work? Where did it come from? Why is it the sole preserve of humans? We set out a self-assembly hypothesis: cultural evolution evolved culturally. We present an evolutionary account that shows this hypothesis to be coherent, plausible, and worthy of further investigation. It has the following steps: (0) in common with other animals, early hominins had significant capacity for social learning; (1) knowledge and skills learned by offspring from their parents began to spread because (...) bearers had more offspring, a process we call CS1 (or Cultural Selection 1); (2) CS1 shaped attentional learning biases; (3) these attentional biases were augmented by explicit learning biases (judgements about what should be copied from whom). Explicit learning biases enabled (4) the high-fidelity, exclusive copying required for fast cultural accumulation of knowledge and skills by a process we call CS2 (or Cultural Selection 2), and (5) the emergence of cognitive processes such as imitation, mindreading and metacognition – ‘cognitive gadgets’ specialised for cultural learning. This self-assembly hypothesis is consistent with archaeological evidence that the stone tools used by early hominins were not dependent on fast, cumulative cultural evolution, and suggests new priorities for research on ‘animal culture’.

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)

My aim in this chapter is to clarify the nature of the shift in Feyerabend’s philosophical thinking in the 1970s, focusing on issues of realism, relativism, and pluralism. Contra-Preston, I argue that realism-relativism is a misleading variable for characterizing Feyerabend’s shift in the 1970s. Rather, I characterize this shift as Feyerabend’s expansion of pluralism and suggest that this shift appears in Feyerabend’s publications starting in the late-1960s (e.g., Feyerabend 1968b, 1969b, 1970a, 1970c). Adopting the terminology of Brown and Kidd (2016), (...) this shift is characterized by a move from arguments for pluralism within science to broader arguments for pluralism in society. I argue that this shift was largely due to: (1) Feyerabend’s rejection of an empiricist demarcation criterion for science in the mid-1960s, and (2) Feyerabend’s incorporation of Mill’s arguments for pluralism into his own publications starting in 1970. This shift can be characterized as a broadening or expanding the scope of Feyerabend’s arguments for pluralism from contexts of scientific knowledge to the broader context of social or cultural (including ethical) knowledge. I articulate this argument with reference to the framework for classifying Feyerabend’s works formulated by Brown and Kidd (2016). Against Brown and Kidd (and Preston), I argue that realism-relativism is a red-herring as a variable for distinguishing Feyerabend’s early and middle works. Brown and Kidd’s distinction between pluralism within science and pluralism in society is a more useful variable for characterizing Feyerabend’s shift in thinking in the 1970s. Whereas Preston (1997) and Brown and Kidd (2016) identify the beginning of Feyerabend’s pluralism in society phase in 1978 with the publication of Science in a Free Society (Feyerabend 1978), I suggest that the relevant shift occurs much earlier, and it appears in Feyerabend’s publications starting in 1970 (Feyerabend 1970a, 1970b). On this understanding, Feyerabend’s philosophical shift (c. 1970) should be viewed as an expansion (or broadening) of the scope of application of his pluralist arguments, inspired by Mill’s ethical arguments for pluralism in society (Mill 1859/1977).

Drawing on the SAGE minutes and other documents, I consider the wider lessons for norms of scientific advising that can be learned from the UK’s initial response to coronavirus in the period January-March 2020, when an initial strategy that planned to avoid total suppression of transmission was abruptly replaced by an aggressive suppression strategy. I introduce a distinction between “normatively light advice”, in which no specific policy option is recommended, and “normatively heavy advice” that does make an explicit recommendation. I (...) argue that, although scientific advisers should avoid normatively heavy advice in normal times in order to facilitate democratic accountability, this norm can be permissibly overridden in situations of grave emergency. SAGE’s major mistake in early 2020 was not that of endorsing a particular strategy, nor that of being insufficiently precautionary, but that of relying too heavily on a specific set of “reasonable worst-case” planning assumptions. I formulate some proposals that assign a more circumscribed role to “worst-case” thinking in emergency planning. In an epilogue, I consider what the implications of my proposals would have been for the UK’s response to the “second wave” of late 2020. (shrink)

This paper presents a detailed analysis of affective persistence and its significance – that is the persistence of affect in the face of countervailing or contradictory evaluative information. More specifically, it appeals to the phenomena of affective persistence to support the claim that a significant portion of the emotional experiences of adult humans involve a kind of normative phenomenology. Its central claim is that by appealing to a distinctive kind of normative phenomenology that emotions exhibit, we get a neat personal (...) level explanation of why affect persists. In doing so it introduces and explores an interesting claim that Ronald de Sousa makes concerning the distinctiveness of emotion, explicating it in terms of the idea of affective persistence. As such, the contribution of the paper is twofold: a thesis about emotional phenomenology qua its normative phenomenology is presented, and that thesis is used to explain something distinctive about our emotional experiences, namely that they often persist in the face of conflicting evaluative judgements and beliefs.

In “Against Arguments from Reference” (Mallon et al., 2009), Ron Mallon, Edouard Machery, Shaun Nichols, and Stephen Stich (hereafter, MMNS) argue that recent experiments concerning reference undermine various philosophical arguments that presuppose the correctness of the causal-historical theory of reference. We will argue three things in reply. First, the experiments in question—concerning Kripke’s Gödel/Schmidt example—don’t really speak to the dispute between descriptivism and the causal-historical theory; though the two theories are empirically testable, we need to look at quite different data (...) than MMNS do to decide between them. Second, the Gödel/Schmidt example plays a different, and much smaller, role in Kripke’s argument for the causal-historical theory than MMNS assume. Finally, and relatedly, even if Kripke is wrong about the Gödel/Schmidt example—indeed, even if the causal-historical theory is not the correct theory of names for some human languages—that does not, contrary to MMNS’s claim, undermine uses of the causalhistorical theory in philosophical research projects.

Under the current Mental Health Act of England and Wales, it is lawful to perform deep brain stimulation in the absence of consent and independent approval.

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)

A fundamental fact is “pure” just in case it has no grounded entities—ex. Tokyo, President Biden, the River Nile, {Socrates}, etc.—among its constituents. Purity is the thesis that every fundamental fact is pure. I argue that Purity is false. My argument begins with a familiar conditional: if Purity is true, then there are no fundamental “grounding facts” or facts about what grounds what. This conditional is accepted by virtually all of Purity’s defenders. However, I argue that it is also the (...) first step toward Purity’s undoing. For, if every grounding fact has a ground, then some grounded entities have “groundmates” or distinct grounded entities that share their full grounds. But, if there are groundmates, then Purity is false. So Purity leads to a contradiction. Therefore, it is false. I close by noting that my argument against Purity also gives us a powerful reason to think that some grounding facts are fundamental. (shrink)

Since its earliest incarnations, just war theory has included the requirement that war must be initiated and waged by a legitimate authority. However, while recent years have witnessed a remarkable resurgence in interest in just war theory, the authority criterion is largely absent from contemporary discussions. In this paper I aim to show that this is an oversight worth rectifying, by arguing that the authority criterion plays a much more important role within just war theorising than is commonly supposed. As (...) standardly understood, the authority criterion provides a necessary condition for the justification of the resort to war, but has no bearing on the question of permissible conduct in war. In opposition, I argue for an alternative interpretation of the criterion, which attributes to it a fundamental role in assessing this latter question. With this revised interpretation in place, I then demonstrate its advantages by applying it to the practical issue of armed conflicts that are initiated and fought by non-traditional belligerents. While several theorists have recognised that this common feature of modern armed conflict poses a challenge to mainstream just war theory in general—and to the authority criterion in particular—I argue that existing discussions frequently misconstrue the nature of the challenge, since they assume the standard interpretation of the authority requirement and its role within the theory. I then show that the revised interpretation provides a clearer account of both the challenge posed by non-traditional belligerency and the kind of response that it requires. (shrink)

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)

Is the brain really a computer? In particular, is our intelligence a computational achievement: is it because our brains are computers that we get on in the world as well as we do? In this paper I will evaluate an ambitious new argument to the contrary, developed in Landgrebe and Smith (2021a, 2022). Landgrebe and Smith begin with the fact that many dynamical systems in the world are difficult or impossible to model accurately (inter alia, because it is intractable to (...) find exact solutions to the differential equations that describe them—meaning we have to approximate—but at the same time they are such that small differences in starting conditions lead to big differences in final conditions, thwarting accurate approximation). Yet we manage to survive and thrive in a world full of such systems. Landgrebe and Smith argue from these premises that it is not because our brains are computers that we get on as well as we do: instead it is because of the various ways that we dynamically couple with such systems, these couplings themselves impossible to model well enough to emulate in silico. Landgrebe and Smith thus defend a dynamical systems model in the lineage of Gibson (1979), Van Gelder (1995), and Thompson (2007), though their focus is on decisively refuting the computationalist alternatives rather than developing the positive account. Here I will defend the claim that human intelligence is genuinely computational (and that whole brain emulation and others forms of AGI may be possible) against this argument. (shrink)

In the debates regarding the ethics of human enhancement, proponents have found it difficult to refute the concern, voiced by certain bioconservatives, that cognitive enhancement violates the autonomy of the enhanced. However, G. Owen Schaefer, Guy Kahane and Julian Savulescu have attempted not only to avoid autonomy-based bioconservative objections, but to argue that cognition-enhancing biomedical interventions can actually enhance autonomy. In response, this paper has two aims: firstly, to explore the limits of their argument; secondly, and more importantly, to develop (...) a more complete understanding of autonomy and its relation to cognitive enhancement. By drawing a distinction between the capacity for autonomy and the exercise and achievement of autonomy and by exploring the possible effects of cognitive enhancement on both competence and authenticity conditions for autonomy, the paper identifies and explains which dimensions of autonomy can and cannot, in principle, be enhanced via direct cognitive interventions. This allows us to draw conclusions regarding the limits of cognitive enhancement as a means for enhancing autonomy. (shrink)

This paper assesses whether Evaluativism, as a view about the nature of unpleasant pains, can meet a specific normative condition. The normative condition says whatever candidate state is offered as an analysis of unpleasant pain should be intrinsically phenomenally bad for its subject to be in. I first articulate a method reflecting this condition, called the normative contrast method, and then frame Evaluativism in detail. The view is then tested through this method. I show that Evaluativism can explain why cases (...) of evaluative thought, with the same contents as unpleasant pains, are not intrinsically phenomenally bad for their subjects to be in by appeal to intentional modes. However, I argue the appeal to perceptuality, which is central to this response is problematic, and therefore it remains unclear whether Evaluativism, as standardly articulated, can meet the normative condition on unpleasant pains.

This article responds to two arguments against ‘Epistemic Perceptualism’, the view that emotional experiences, as involving a perception of value, can constitute reasons for evaluative belief. It first provides a basic account of emotional experience, and then introduces concepts relevant to the epistemology of emotional experience, such as the nature of a reason for belief, non-inferentiality, and prima facie vs. conclusive reasons, which allow for the clarification of Epistemic Perceptualism in terms of the Perceptual Justificatory View. It then challenges two (...) arguments which purport to show that emotional experience is not a source of reasons for evaluative belief. The first argument claims that because normative why-questions are always appropriate in the case of emotions, then emotions can never be conclusive reasons for corresponding evaluative beliefs. The second purports to show that appeal to emotional experience as a source of reasons for evaluative beliefs renders emotions problematically self-justifying, and since emotions cannot be self-justifying, they cannot provide any sort of reason for corresponding evaluative beliefs. This article responds to these arguments, and in doing so shows there is still much to be learned about the epistemology of emotional experience by drawing analogies with perceptual experience.

Experimental design is one aspect of a scientific method. A well-designed, properly conducted experiment aims to control variables in order to isolate and manipulate causal effects and thereby maximize internal validity, support causal inferences, and guarantee reliable results. Traditionally employed in the natural sciences, experimental design has become an important part of research in the social and behavioral sciences. Experimental methods are also endorsed as the most reliable guides to policy effectiveness. Through a discussion of some of the central concepts (...) associated with experimental design, including controlled variation and randomization, this chapter will provide a summary of key ethical issues that tend to arise in experimental contexts. In addition, by exploring assumptions about the nature of causation and by analyzing features of causal relationships, systems, and inferences in social contexts, this chapter will summarize the ways in which experimental design can undermine the integrity of not only social and behavioral research but policies implemented on the basis of such research.

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)
