I respond to Tim Smartt’s (2023) skepticism about epistemic blame. Smartt’s skepticism is based on the claims that (i) mere negative epistemic evaluation can better explain everything proponents of epistemic blame say we need epistemic blame to explain; and (ii) no existing account of epistemic blame provides a plausible account of the putative force that any response deserving the label “blame” ought to have. He focuses primarily on the prominent “relationship-based” account of epistemic blame to defend these claims, arguing that (...) the account is explanatorily idle, and cannot distinguish between epistemically excused and epistemically blameworthy agents. I argue that Smartt mischaracterizes the account’s role for judgments of epistemic relationship impairment, leading to mistaken claims about the account’s predictions. I also argue that the very feature of the account that Smartt mischaracterizes is key to understanding what epistemic blame does for our epistemic responsibility practices that mere negative epistemic evaluation cannot.

We regularly make graded normative judgements in the epistemic domain. Recent work in the literature examines degrees of justification, degrees of rationality, and degrees of assertability. This paper addresses a different dimension of the gradeability of epistemic normativity, one that has been given little attention. How should we understand degrees of epistemic criticizability? In virtue of what sorts of factors can one epistemic failing be worse than another? The paper develops a dual-factor view of degrees of epistemic criticizability. According to (...) the view, degrees of epistemic criticizability are (i) an inverse function of degrees of doxastic justification and (ii) a function of degrees of agent culpability. The paper develops an account of each factor, and explains how they should be weighted. The paper also addresses the importance of modelling degrees of epistemic criticizability in a broader context. I focus on the role that such a model can play in the ethics of epistemic criticism. (shrink)

The paper critically examines recent work on justifications and excuses in epistemology. I start with a discussion of Gerken’s claim that the “excuse maneuver” is ad hoc. Recent work from Timothy Williamson and Clayton Littlejohn provides resources to advance the debate. Focusing in particular on a key insight in Williamson’s view, I then consider an additional worry for the so-called excuse maneuver. I call it the “excuses are not enough” objection. Dealing with this objection generates pressure in two directions: one (...) is to show that excuses are a positive enough normative standing to help certain externalists with important cases; the other is to do so in a way that does not lead back to Gerken’s objection. I show how a Williamson-inspired framework is flexible enough to deal with both sources of pressure. Perhaps surprisingly, I draw on recent virtue epistemology. (shrink)

Why comply with epistemic norms? In this paper, I argue that complying with epistemic norms, engaging in epistemically responsible conduct, and being epistemically trustworthy are constitutive elements of maintaining good epistemic relations with oneself and others. Good epistemic relations are in turn both instrumentally and finally valuable: they enable the kind of coordination and knowledge acquisition underpinning much of what we tend to associate with a flourishing human life; and just as good interpersonal relations with others can be good for (...) their own sake, standing in good epistemic relations is good for its own sake. On my account, we have reason to comply with epistemic norms because it is a way of respecting the final value of something that also tends to be an instrumentally valuable thing: good epistemic relations. Situating the account within the recent social turn in debates about epistemic instrumentalism, I argue that the dual‐value aspect of good epistemic relations can explain important anti‐instrumentalist intuitions, in a well‐motivated way, within a broadly instrumentalist framework.

Epistemological Disjunctivism is a view about paradigm cases of perceptual knowledge. Duncan Pritchard claims that it is particularly well suited to accounting for internalist and externalist intuitions. A number of authors have disputed this claim, arguing that there are problems for Pritchard’s way with internalist intuitions. I share the worry. However, I don’t think it has been expressed as effectively as it can be. My aim in this paper is to present a new way of formulating the worry, in terms (...) of an “explanatory challenge”. The explanatory challenge is a simple, yet powerful and illuminating challenge for Epistemological Disjunctivism. It is illuminating in the sense that it shows us why Epistemological Disjunctivism must take on certain internalistically problematic commitments. A secondary aim of this paper is to examine whether the recently much-discussed distinction between justifications and excuses in epistemology can support an adequate response. I will argue that it cannot. (shrink)

I address an intuition commonly endorsed by metaphysicians, that there must be a fundamental layer of reality, i.e., that chains of ontological dependence must terminate: there cannot be turtles all the way down. I discuss applications of this intuition with reference to Bradley’s regress, composition, realism about the mental and the cosmological argument. I discuss some arguments for the intui- tion, but argue that they are unconvincing. I conclude by making some suggestions for how the intuition should be argued for, (...) and discussing the ramifications of giving the justification I think best. (shrink)

In artificial intelligence, recent research has demonstrated the remarkable potential of Deep Convolutional Neural Networks (DCNNs), which seem to exceed state-of-the-art performance in new domains weekly, especially on the sorts of very difficult perceptual discrimination tasks that skeptics thought would remain beyond the reach of artificial intelligence. However, it has proven difficult to explain why DCNNs perform so well. In philosophy of mind, empiricists have long suggested that complex cognition is based on information derived from sensory experience, often appealing to (...) a faculty of abstraction. Rationalists have frequently complained, however, that empiricists never adequately explained how this faculty of abstraction actually works. In this paper, I tie these two questions together, to the mutual benefit of both disciplines. I argue that the architectural features that distinguish DCNNs from earlier neural networks allow them to implement a form of hierarchical processing that I call “transformational abstraction”. Transformational abstraction iteratively converts sensory-based representations of category exemplars into new formats that are increasingly tolerant to “nuisance variation” in input. Reflecting upon the way that DCNNs leverage a combination of linear and non-linear processing to efficiently accomplish this feat allows us to understand how the brain is capable of bi-directional travel between exemplars and abstractions, addressing longstanding problems in empiricist philosophy of mind. I end by considering the prospects for future research on DCNNs, arguing that rather than simply implementing 80s connectionism with more brute-force computation, transformational abstraction counts as a qualitatively distinct form of processing ripe with philosophical and psychological significance, because it is significantly better suited to depict the generic mechanism responsible for this important kind of psychological processing in the brain.

This book provides a framework for thinking about foundational philosophical questions surrounding machine learning as an approach to artificial intelligence. Specifically, it links recent breakthroughs in deep learning to classical empiricist philosophy of mind. In recent assessments of deep learning's current capabilities and future potential, prominent scientists have cited historical figures from the perennial philosophical debate between nativism and empiricism, which primarily concerns the origins of abstract knowledge. These empiricists were generally faculty psychologists; that is, they argued that the active (...) engagement of general psychological faculties-such as perception, memory, imagination, attention, and empathy-enables rational agents to extract abstract knowledge from sensory experience. This book explains a number of recent attempts to model roles attributed to these faculties in deep neural network based artificial agents by appeal to the faculty psychology of philosophers such as Aristotle, Ibn Sina (Avicenna), John Locke David Hume, William James, and Sophie de Grouchy. It illustrates the utility of this interdisciplinary connection by showing how it can provide benefits to both philosophy and computer science: computer scientists can continue to mine the history of philosophy for ideas and aspirational targets to hit on the way to more robustly rational artificial agents, and philosophers can see how some of the historical empiricists' most ambitious speculations can be realized in specific computational systems.

We offer an overview of what we take to be the main themes in Annalisa Coliva’s book, Moore and Wittgenstein: Scepticism, Certainty and Common Sense. In particular, we focus on the ‘framework reading’ that she offers of Wittgenstein’s On Certainty and its anti-sceptical implications. While broadly agreeing with the proposal that Coliva puts forward on this score, we do suggest one important supplementation to the view—viz., that this way of dealing with radical scepticism needs to be augmented with an account (...) of the meta-sceptical problem which this proposal generates, which we call epistemic vertigo.

The connection between whole and part is intimate: not only can we share the same space, but I’m incapable of leaving my parts behind; settle the nonmereological facts and you thereby settle what is a part of what; wholes don’t seem to be an additional ontological commitment over their parts. Composition as identity promises to explain this intimacy. But it threatens to make the connection too intimate, for surely the parts could have made a different whole and the whole have (...) had different parts. In this paper I attempt to offer an account of parthood that is intimate enough but not too intimate: the parts generate the whole, but they are not themselves the whole. (shrink)

A prominent objection to the knowledge norm of belief is that it is too demanding or too strong. The objection is commonly framed in terms of the idea that there is a tight connection between norm violation and the appropriateness of criticism or blame. In this paper I do two things. First, I argue that this way of motivating the objection leads to an impasse in the epistemic norms debate. It leads to an impasse when knowledge normers invoke excuses to (...) explain away a prima facie connection between blamelessness and justified belief. Second, I argue that a way out of the impasse becomes available when we take a closer look at some distinctions in the theory of responsibility. There are at least three different notions of responsibility relevant here. I argue that a weaker notion of responsibility – attributability – should be used to motivate the objection that the knowledge norm of belief is too strong. Insofar as the proposal motivates the objection without appeal to blamelessness, it opens up space to move beyond the impasse. (shrink)

How should we determine the distribution of psychological traits—such as Theory of Mind, episodic memory, and metacognition—throughout the Animal kingdom? Researchers have long worried about the distorting effects of anthropomorphic bias on this comparative project. A purported corrective against this bias was offered as a cornerstone of comparative psychology by C. Lloyd Morgan in his famous “Canon”. Also dangerous, however, is a distinct bias that loads the deck against animal mentality: our tendency to tie the competence criteria for cognitive capacities (...) to an exaggerated sense of typical human performance. I dub this error “anthropofabulation”, since it combines anthropocentrism with confabulation about our own prowess. Anthropofabulation has long distorted the debate about animal minds, but it is a bias that has been little discussed and against which the Canon provides no protection. Luckily, there is a venerable corrective against anthropofabulation: a principle offered long ago by David Hume, which I call “Hume’s Dictum”. In this paper, I argue that Hume’s Dictum deserves a privileged place next to Morgan’s Canon in the methodology of comparative psychology, illustrating my point through a discussion of the debate over Theory of Mind in nonhuman animals.

Our prominent definitions of cognition are too vague and lack empirical grounding. They have not kept up with recent developments, and cannot bear the weight placed on them across many different debates. I here articulate and defend a more adequate theory. On this theory, behaviors under the control of cognition tend to display a cluster of characteristic properties, a cluster which tends to be absent from behaviors produced by non-cognitive processes. This cluster is reverse-engineered from the empirical tests that comparative (...) psychologists use to determine whether a behavior was generated by a cognitive or a non-cognitive process. Cognition should be understood as the natural kind of psychological process that non-accidentally exhibits the properties assessed by these tests (as well as others we have not yet discovered). Finally, I review two plausible neural accounts of cognition's underlying mechanisms?one based in localization of function to particular brain regions and another based in the more recent distributed networks approach to neuroscience?which would explain why these properties non-accidentally cluster. While this notion of cognition may be useful for a number of debates, I here focus on its application to a recent crisis over the distinction between cognition and association in comparative psychology.

Philosophers and cognitive scientists have worried that research on animal mind-reading faces a ‘logical problem’: the difficulty of experimentally determining whether animals represent mental states (e.g. seeing) or merely the observable evidence (e.g. line-of-gaze) for those mental states. The most impressive attempt to confront this problem has been mounted recently by Robert Lurz. However, Lurz' approach faces its own logical problem, revealing this challenge to be a special case of the more general problem of distal content. Moreover, participants in this (...) debate do not agree on criteria for representation. As such, future debate should either abandon the representational idiom or confront underlying semantic disagreements. (shrink)

In this short paper, I critically examine Veli Mitova’s proposal that social-identity groups can have collective epistemic reasons. My primary focus is the role of privileged access in her account of how collective reasons become epistemic reasons for social-identity groups. I argue that there is a potentially worrying structural asymmetry in her account of two different types of cases. More specifically, the mechanisms at play in cases of “doxastic reasons” seem fundamentally different from those at play in cases of “epistemic-conduct (...) reasons”. The upshot is a need for further explanation of what unifies these dimensions of the account. (shrink)

Works of music do not appear to be concrete objects; but they do appear to be created by composers, and abstract objects do not seem to be the kind of things that can be created. In this paper I aim to develop an ontological position that lets us salvage the creativity intuition without either adopting an ontology of created abstracta or identifying musical works with concreta. I will argue that there are no musical works in our ontology, but nevertheless the (...) English sentences we want to hold true are literally true. I rely on a meta-ontological view whereby ‘a exists’ can be true without committing us to an entity that is a. This meta-ontological view is illustrated by its application to the familiar example of the statue and the clay. I argue that my account of musical ontology fares better on the balance of costs and benefits than its rivals. (shrink)

This paper attempts to locate, within an actualist ontology, truthmakers for modal truths: truths of the form or . In Sect. 1 I motivate the demand for substantial truthmakers for modal truths. In Sect. 21 criticise Armstrong's account of truthmakers for modal truths. In Sect. 31 examine essentialism and defend an account of what makes essentialist attributions true, but I argue that this does not solve the problem of modal truth in general. In Sect. 41 discuss, and dismiss, a theistic (...) account of the source of modal truth proposed by Alexander Pruss. In Sect. 5 I offer a means of (dis)solving the problem. (shrink)

Responsible leadership is rare. It is not that most leaders are irresponsible, but responsibility in leadership is frequently defined so that an important connotation of responsible leadership is ignored. This article equates responsible leadership with virtuousness. Using this connotation implies that responsible leadership is based on three assumptions—eudaemonism, inherent value, and amplification. Secondarily, this connotation produces two important outcomes—a fixed point for coping with change, and benefits for constituencies who may never be affected otherwise. The meaning and advantages of responsible (...) leadership as virtuous leadership are discussed. (shrink)

There is a widely accepted distinction between being directly responsible for a wrongdoing versus being somehow indirectly or vicariously responsible for the wrongdoing of another person or collective. Often this is couched in analyses of complicity, and complicity’s role in the relationship between individual and collective wrongdoing. Complicity is important because, inter alia, it allows us to make sense of individuals who may be blameless or blameworthy to a relatively low degree for their immediate conduct, but are nevertheless blameworthy to (...) a higher degree for their implication in some larger (or another person’s) wrongdoing. In this paper, I argue that there is a distinctively epistemic kind of complicity. First, I motivate the distinction between direct and vicarious responsibility with three interlocking arguments, respectively appealing to: i) the structure of rational agency; ii) linguistic considerations; iii) the role of “principal vs. accomplice” in legal doctrine. I show how these arguments naturally extend to the epistemic domain, motivating an epistemic form of vicarious responsibility. I then examine complicity as a mechanism of vicarious epistemic responsibility. To fill this out, I engage with an epistemic analogue of the debate about the role of intention versus causal contribution in complicity. I propose a Casual Account of Epistemic Complicity, arguing that it accommodates a wide range of cases, and enables fine-grained explanations of degrees of culpability for epistemic complicity. With an adequate account of epistemic complicity on hand, we can explain what is objectionable about an important class of epistemic agent who, on an individual level, may be epistemically blameless or blameworthy to a relatively low degree, but whose relation to other individuals or collectives nevertheless makes them epistemically blameworthy to a higher degree. I explore some broader implications of this result. (shrink)

Blameless norm violation in young children is an underexplored phenomenon in epistemology. An understanding of it is important for accounting for the full range of normative standings at issue in debates about epistemic norms, and the internalism-externalism debate generally. More specifically, it is important for proponents of factive epistemic norms. I examine this phenomenon and put forward a positive proposal. I claim that we should think of the normative dimension of certain actions and attitudes of young children in terms of (...) a kind of “prospective agency”. I argue that the most sophisticated account of exculpatory defenses in epistemology – due to Clayton Littlejohn – does not provide an adequate model for exculpatory defenses of prospective agents. The aim is not primarily to challenge Littlejohn. Rather, I engage with his framework as a way of setting up my positive proposal. I call it the “heuristic model”. (shrink)

The functionalist approach to kinds has suffered recently due to its association with law-based approaches to induction and explanation. Philosophers of science increasingly view nomological approaches as inappropriate for the special sciences like psychology and biology, which has led to a surge of interest in approaches to natural kinds that are more obviously compatible with mechanistic and model-based methods, especially homeostatic property cluster theory. But can the functionalist approach to kinds be weaned off its dependency on laws? Dan Weiskopf has (...) recently offered a reboot of the functionalist program by replacing its nomological commitments with a model-based approach more closely derived from practice in psychology. Roughly, Weiskopf holds that the natural kinds of psychology will be the functional properties that feature in many empirically successful cognitive models, and that those properties need not be localized to parts of an underlying mechanism. I here skeptically examine the three modeling practices that Weiskopf thinks introduce such non-localizable properties: fictionalization, reification, and functional abstraction. In each case, I argue that recognizing functional properties introduced by these practices as autonomous kinds comes at clear cost to those explanations’ counterfactual explanatory power. At each step, a tempting functionalist response is parochialism: to hold that the false or omitted counterfactuals fall outside the modeler’s explanatory aims, and so should not be counted against functional kinds. I conclude by noting the dangers this attitude poses to scientific disagreement, inviting functionalists to better articulate how the individuation conditions for functional kinds might outstrip the perspective of a single modeler.

In this book, Yagisawa defends a type of realism about merely possible worlds and individuals.1 The view defended is much closer to David Lewis’s genuine modal realism than it is to any kind of actualist or ersatzist modal realism, and I think the best way of understanding Yagisawa’s view will be to see where it differs from Lewis’s. To that end, let’s briefly remind ourselves of Lewis’s theory.

A. F. Norman has recently suggested that a hitherto overlooked passage in Suidas is a fragment from the history of Eunapius of Sardis. He is clearly correct in referring the passage to an incident at the siege of Maiozamalcha during the Persian campaign of the emperor Julian, but I am not so sure that he is right in ascribing it to Eunapius, or in the conclusions he draws from this ascription. I give in parallel columns the accounts of Ammianus Marcellinus, (...) Zosimus, and the passage from Suidas, together with a further version of the incident, unfortunately without names, from the pen of Libanius. (shrink)

The application of digital humanities techniques to philosophy is changing the way scholars approach the discipline. This paper seeks to open a discussion about the difficulties, methods, opportunities, and dangers of creating and utilizing a formal representation of the discipline of philosophy. We review our current project, the Indiana Philosophy Ontology (InPhO) project, which uses a combination of automated methods and expert feedback to create a dynamic computational ontology for the discipline of philosophy. We argue that our distributed, expert-based approach (...) to modeling the discipline carries substantial practical and philosophical benefits over alternatives. We also discuss challenges facing our project (and any other similar project) as well as the future directions for digital philosophy afforded by formal modeling. (shrink)

Simon Blackburn posed a dilemma for any realist attempt to identify the source of necessity. Either the facts appealed to to ground modal truth are themselves necessary, or they are contingent. If necessary, we begin the process towards regress; but if contingent, we undermine the necessity whose source we wanted to explain. Bob Hale attempts to blunt both horns of this dilemma. In this paper I examine their respective positions and attempt to clear up some confusions on either side. I (...) come to defend Hale’s conclusion that both horns of the dilemma can be resisted. I end by defending my own account of the source of necessity, and showing why it does not fall victim to Blackburn’s problem. (shrink)

This book is about our practice of criticizing one another for epistemic failings. We clearly evaluate and critique one another for forming unjustified beliefs, harboring biases, and pursuing faulty methods of inquiry. But what is the nature of this criticism? Does it ever rise to the level of blame? The question is puzzling because there are competing sources of pressure in our intuitions about “epistemic blame,” ones not easy to reconcile. The more blame-like a response is, the less at home (...) in the epistemic domain it seems—but the more at home in the epistemic domain a response is, the less blame-like it seems. These competing sources of pressure constitute a puzzle about epistemic blame. The most promising solution to this puzzle focuses on the interpersonal side of epistemic normativity. Members of an epistemic community stand in an “epistemic relationship,” and epistemic blame is a way of modifying this relationship. Understanding epistemic blame as a distinctive kind of relationship modification locates a response that is both robustly blame-like, and entirely at home in the epistemic domain. Epistemic relationships can also illuminate a unique set of issues in the “ethics of epistemic blame,” ones that mirror corresponding issues in the ethics of moral blame. The book examines the scope of appropriate epistemic blame, standing to epistemically blame, and the value of epistemic blame in our social and political lives. Throughout the investigation, a better understanding of the parallels and points of interaction between the epistemic and other normative domains emerges. -/- **Front matter, ToC, and Introduction uploaded here**.

In this paper I argue that warrant for Lewis’ Modal Realism is unobtainable. I consider two familiar objections to Lewisian realism – the modal irrelevance objection and the epistemological objection – and argue that Lewis’ response to each is unsatisfactory because they presuppose claims that only the Lewisian realist will accept. Since, I argue, warrant for Lewisian realism can only be obtained if we have a response to each objection that does not presuppose the truth of Lewisian realism, this circularity (...) is vicious. I end by contrasting Lewis’ methodology with Forrest’s in order to illustrate a rival method that does not fall victim to the objection I lay against Lewis. (shrink)

When is life-sustaining treatment not in the best interests of a minimally conscious child? This is an extremely difficult question that incites seemingly intractable debate. And yet, it is the question courts in England and Wales have set out to answer in disputes about appropriate medical treatment for children.

I argue that Agustín Rayo’s symmetric ‘just is’ statements cannot be defined in terms of notions like essence, grounding or metaphysical truth-conditions. I go on to argue that one of these latter notions, which allow us to express an asymmetric relationship between facts, is needed to do some of the work that Rayo intends ‘just is’ statements to do, such as stating reductionist claims.

This paper is an investigation of metaphysical nihilism: the view that there could have been no contingent or concrete objects. I begin by showing the connections of the nihilistic theses to other philosophical doctrines. I then go on to look at the arguments for and against metaphysical nihilism in the literature and find both to be flawed. In doing so I will look at the nature of abstract objects, the nature of spacetime and mereological simples, the existence of the empty (...) set, the dependence of universals on particulars, and other general questions of ontology.

In this paper I argue that warrant for Lewis ' principle of recombination presupposes warrant for a combinatorial analysis of intrinsicality, which in turn presupposes warrant for the principle of recombination. This, I claim, leads to a vicious circularity: warrant for neither doctrine can get off the ground.

I reply to Miller, Sider and Skow’s comments on my book The Moving Spotlight. I aim to make clearer the epistemic argument against non-presentist A-theories of time, and why I avoid it.
