This study takes inquiry as the starting point for epistemological theorising. It uses this idea to develop new and systematic answers to some of the most fundamental questions in epistemology, including about the nature of core epistemic phenomena as well as their value and the extent to which we possess them.

Traditionally, epistemologists have held that only truth-related factors matter in the question of whether a subject can be said to know a proposition. Various philosophers have recently departed from this doctrine by claiming that the answer to this question also depends on practical concerns. They take this move to be warranted by the fact that people’s knowledge attributions appear sensitive to contextual variation, in particular variation due to differing stakes. This paper proposes an alternative explanation of the aforementioned fact, one (...) that allows us to stick to the orthodoxy. The alternative applies the conceptual spaces approach to the concept of knowledge. With knowledge conceived of spatially, the variability in knowledge attributions follows from recent work on identity, according to which our standards for judging things (including concepts) to be identical are context-dependent. On the proposal to be made, it depends on what is at stake in a context whether it is worth distinguishing between knowing and being at least close to knowing. (shrink)

This paper highlights some connections between work on truth approximation and work in social epistemology, in particular work on peer disagreement. In some of the literature on truth approximation, questions have been addressed concerning the efficiency of research strategies for approximating the truth. So far, social aspects of research strategies have not received any attention in this context. Recent findings in the field of opinion dynamics suggest that this is a mistake. How scientists exchange and take into account information about (...) each others’ beliefs may greatly influence the accuracy and speed with which the scientific community as a whole approximates the truth. On the other hand, social epistemologists concerned with peer disagreement have so far neglected the question of how practices of responding to disagreements with peers fare with respect to the goal of approximating the truth. Again, work on opinion dynamics shows that this may be a mistake, and that how we ought to respond to disagreements with our peers may depend on the specific purposes of our investigations. (shrink)

The literature on the nature of understanding can be divided into two broad camps. Explanationists believe that it is knowledge of explanations that is key to understanding. In contrast, their manipulationist rivals maintain that understanding essentially involves an ability to manipulate certain representations. The aim of this paper is to provide a novel knowledge based account of understanding. More specifically, it proposes an account of maximal understanding of a given phenomenon in terms of fully comprehensive and maximally well-connected knowledge of (...) it and of degrees of understanding in terms of approximations to such knowledge. It is completed by a contextualist semantics for outright attributions of understanding according to which an attribution of understanding is true of one just in case one knows enough about it to perform some contextually determined task. It is argued that this account has an edge over both its explanationist and manipulationist competitors. (shrink)

According to a much discussed argument, reliabilism is defective for making knowledge too easy to come by. In a recent paper, Weisberg aims to show that this argument relies on a type of reasoning that is rejectable on independent grounds. We argue that the blanket rejection that Weisberg recommends of this type of reasoning is both unwarranted and unwelcome. Drawing on an older discussion in the philosophy of science, we show that placing some relatively modest restrictions on the said type (...) of reasoning suffices to block the anti-reliabilist argument.

Assertion is the central vehicle for the sharing of knowledge. Whether knowledge is shared successfully often depends on the quality of assertions: good assertions lead to successful knowledge sharing, while bad ones don't. In Sharing Knowledge, Christoph Kelp and Mona Simion investigate the relation between knowledge sharing and assertion, and develop an account of what it is to assert well. More specifically, they argue that the function of assertion is to share knowledge with others. It is this function that (...) supports a central norm of assertion according to which a good assertion is one that has the disposition to generate knowledge in others. The book uses this functionalist approach to motivate further norms of assertion on both the speaker and the hearer side and investigates ramifications of this view for other questions about assertion.

Recent clinical trials show that psychedelics such as LSD and psilocybin can be given safely in controlled conditions, and can cause lasting psychological benefits with one or two administrations. Supervised psychedelic sessions can reduce symptoms of anxiety, depression, and addiction, and improve well-being in healthy volunteers, for months or even years. But these benefits seem to be mediated by "mystical" experiences of cosmic consciousness, which prompts a philosophical concern: do psychedelics cause psychological benefits by inducing false or implausible beliefs about (...) the metaphysical nature of reality? This book is the first scholarly monograph in English devoted to the philosophical analysis of psychedelic drugs. Its central focus is the apparent conflict between the growing use of psychedelics in psychiatry and the philosophical worldview of naturalism. Within the book, Letheby integrates empirical evidence and philosophical considerations in the service of a simple conclusion: this "Comforting Delusion Objection" to psychedelic therapy fails. While exotic metaphysical ideas do sometimes come up, they are not, on closer inspection, the central driver of change in psychedelic therapy. Psychedelics lead to lasting benefits by altering the sense of self, and changing how people relate to their own minds and lives-not by changing their beliefs about the ultimate nature of reality. The upshot is that a traditional conception of psychedelics as agents of insight and spirituality can be reconciled with naturalism (the philosophical position that the natural world is all there is). Controlled psychedelic use can lead to genuine forms of knowledge gain and spiritual growth-even if no Cosmic Consciousness or transcendent divine Reality exists. Philosophy of Psychedelics is an indispensable guide to the literature for researchers already engaged in the field of psychedelic psychiatry, and for researchers-especially philosophers-who want to become acquainted with this increasingly topical field.

This paper aims to develop a novel account of the normativity of assertion. Its core thesis is that assertion has an etiological epistemic function, viz. to generate knowledge in hearers. In conjunction with a general account of etiological functions and their normative import, it is argued that an assertion is epistemically good if and only if it has the disposition to generate knowledge in hearers. In addition, reason is provided to believe that it makes sense to regulate the practice of (...) assertion by a speaker rule—and, more specifically, by a knowledge rule—as so regulating assertion contributes to ensuring that assertion fulfils its etiological function reliably. (shrink)

Using a vague predicate can make commitments about the appropriate use of that predicate in the remaining part of the discourse. For instance, if I assert that some particular pig is fat, I am committed to judging any fatter pig to be fat as well. We can model this update effect by recognizing that truth depends both on the state of the world and on the state of the discourse: the truth conditions of ‘This pig is fat’ rule out evaluation (...) points for which the pig in question in world w is thinner than the cutoff for fatness in the discourse d. Then disagreements about taste are disagreements about the discourse. Unlike disagreements about the world, disagreements about the discourse can be faultless, given that none of the discourse participants has privileged authority to make pronouncements about conventions for appropriate use of a predicate. Thus on the dynamic view developed here, whether or not a dispute about taste turns out to be faultless depends in part on predictable features of the previous discourse. On this account, faultless disagreement involving predicates of personal taste does not force relativizing truth to a judge or assessor. (shrink)

In this paper, we develop a general normative framework for criticisability, blamelessness and blameworthiness in action. We then turn to the debate on norms of assertion. We show that an application of this framework enables champions of the so-called knowledge rule of assertion to offer a theoretically motivated response to a number of putative counterexamples in terms of blamelessness. Finally, we argue that, on closer inspection, the putative counterexamples serve to confirm the knowledge rule and disconfirm rival views.

Can we engineer conceptual change? While a positive answer to this question would be exciting news for philosophy, there has been a growing number of pessimistic voices in the literature. This paper resists this trend. Its central aim is to argue not only that conceptual engineering is possible but also that it is not even distinctively hard. In order to achieve this, we will develop a novel approach to conceptual engineering that has two key components. First, it proposes a reorientation (...) of the conceptual engineering project away from fixing conceptual defects and towards bringing about conceptual innovation. Second, it offers a new account of when conceptual engineering is successful in terms of etiological functions. We then turn to the reasons that have motivated various forms of pessimism about conceptual engineering and show that, on our novel approach, none of them stands up to scrutiny. (shrink)

This paper develops a novel, bifocal account of trustworthiness according to which both trustworthinesssimpliciter(as in ‘Ann is trustworthy’) and trustworthiness tophi(as in ‘Ann is trustworthy when it comes to keeping your secrets’) are analysed in terms of dispositions to fulfil one's obligations. We also offer a systematic account of the relation between the two types of trustworthiness, an account of degrees of trustworthiness and comparative trustworthiness, as well as a view of permissible trustworthiness attribution.

This paper connects two important debates in epistemology—to wit, on the goal of inquiry and on the nature of understanding—and offers a unified knowledge-based account of both.

Suppose you ask yourself whether your father's record collection includes a certain recording of The Trout and venture to find out. At that time, you embark on an inquiry into whether your father owns the relevant recording. Your inquiry is a project with a specific goal: finding out whether your father owns the recording. This fact about your inquiry generalizes: inquiry is a goal-directed enterprise. A specific inquiry can be individuated by the question it aims to answer and by who (...) aims to answer the question. Your inquiry into whether your father owns the recording differs from your inquiry into how many records your father owns because different questions are being asked. Your inquiry into whether your father owns the recording differs from my inquiry into whether he does because different people are inquiring. The goal of inquiry into a given question by an agent, α, can be characterized, neutrally, as α's having the answer to that question. I will here focus only on inquiries into whether questions and characterize the goal of inquiry into whether φ by α as α's having the answer to the question whether φ. (shrink)

According to virtue epistemology, knowledge involves cognitive success that is due to cognitive competence. This paper explores the prospects of a virtue theory of knowledge that, so far, has no takers in the literature. It combines features from a couple of different virtue theories: like Pritchard's [forthcoming; et al. 2010] view, it qualifies as what I call an ‘impure’ version of virtue epistemology, according to which the competence condition is supplemented by an additional condition; like Sosa's 2007, 2010 view, it (...) construes the ‘because’ relation at issue in the competence condition in terms of competence manifestation. I argue that this virtue epistemology can steer clear of a number of old and new problems that arise for its rivals on both sides. (shrink)

Recent knowledge first epistemology features a number of different accounts of justified belief, including a knowledge first reductionism according to which to believe justifiably is to know Sutton, Littlejohn, Williamson, a knowledge first version of accessibilism Millar and a knowledge first version of mentalism Bird. This paper offers a knowledge first version of virtue epistemology and argues that it is preferable to its knowledge first epistemological rivals: only knowledge first virtue epistemology manages to steer clear of a number of problems (...) that its competition encounters.

In a comprehensive and innovative reassessment of the discipline, this book argues that classical and contemporary social theories must be studied in relation to the ambition that shaped and established sociology: the ambition to comprehend the relationship between social and moral life. Surveying a range of sociological analyses from Comte to feminism, postmodernism and rational choice theory, this book examines the various attempts that have been made to reconstruct the discipline over the last century, and the challenges facing it today. (...) The book situates sociology in its historical, philosophical and theological contexts and examines how the founders of the discipline developed competing analyses of the processes elementary to social and moral life through their distinctive sociological contributions. Individual chapters examine `Human Sociology', `Sacred Sociology', `Tragic Sociology', `Heroic Sociology' and `Normative Sociology'. The book moves on to discuss post-classical thought, and the attempted reconstruction of the subject. Separate chapters are devoted to `Conflict Sociology', `Feminist Sociology', `Racial Sociology', `Rational Sociology' and `Post//Modern Sociology'. The result is a landmark work in recent sociological study. Accomplished, erudite and alive with ideas, the book will be required reading for students of sociology, social theory, religious studies and cultural studies. (shrink)

Users of psychedelic drugs often report that their sense of being a self or ‘I’ distinct from the rest of the world has diminished or altogether dissolved. Neuroscientific study of such ‘ego dissolution’ experiences offers a window onto the nature of self-awareness. We argue that ego dissolution is best explained by an account that explains self-awareness as resulting from the integrated functioning of hierarchical predictive models which posit the existence of a stable and unchanging entity to which representations are bound. (...) Combining recent work on the ‘integrative self' and the phenomenon of self-binding with predictive processing principles yields an explanation of ego dissolution according to which self-representation is a useful Cartesian fiction: an ultimately false representation of a simple and enduring substance to which attributes are bound which serves to integrate and unify cognitive processing across levels and domains. The self-model is not a mere narrative posit, as some have suggested; it has a more robust and ubiquitous cognitive function than that. But this does not mean, as others have claimed, that the self-model has the right attributes to qualify as a self. It performs some of the right kinds of functions, but it is not the right kind of entity. Ego dissolution experiences reveal that the self-model plays an important binding function in cognitive processing, but the self does not exist. (shrink)

This paper raises a problem for so-called safety-based conceptions of knowledge: It is argued that none of the versions of the safety condition that can be found in the literature succeeds in identifying a necessary condition on knowledge. Furthermore, reason is provided to believe that the argument generalizes at least in the sense that there can be no version of the safety condition that does justice to the considerations motivating a safety condition whilst, at the same time, being requisite for (...) knowledge.

What is the nature of deep disagreement? In this paper, I consider two similar albeit seemingly rival answers to this question: the Wittgensteinian theory, according to which deep disagreements are disagreements over hinge propositions, and the fundamental epistemic principle theory, according to which deep disagreements are disagreements over fundamental epistemic principles. I assess these theories against a set of desiderata for a satisfactory theory of deep disagreement, and argue that while the fundamental epistemic principle theory does better than the Wittgensteinian (...) theory on this score, the fundamental epistemic principle theory nevertheless struggles to explain the variety of deep disagreement.

If dangerous climate change is to be avoided, it is vital that carbon sinks such as tropical rainforests are protected. But protecting them has costs. These include opportunity costs: the potential economic benefits which those who currently control rainforests have to give up when they are protected. But who should bear those costs? Should countries which happen to have rainforests within their territories sacrifice their own economic development, because of our broader global interests in protecting key carbon sinks? This essay (...) develops an argument from the “principle of fairness,” which seeks to establish that outsiders should pay states with rainforests so as to share the costs of protection. If they do not, they can be condemned for free-riding on forest states. The argument is, I suggest, compelling and also capable of enjoying support from adherents of a wide variety of positions on global justice. (shrink)

In Kelp, it is argued that there are epistemic Frankfurt cases that serve to show that knowledge does not require safety from error. In this paper, these Frankfurt cases are revisited. It is first argued that a recent response to the earlier argument by Duncan Pritchard remains unsatisfactory. Then it is shown that Frankfurt cases impact a much wider range of accounts. Specifically, it is argued in some detail that, in conjunction with the infamous Fake Barn cases, they generate (...) a problem for the two most prominent virtue theoretic accounts of knowledge, due to Ernest Sosa and John Greco.

Struggles over precious resources such as oil, water, and land are increasingly evident in the contemporary world. States, indigenous groups, and corporations vie to control access to those resources, and the benefits they provide. These conflicts are rapidly spilling over into new arenas, such as the deep oceans and the Polar regions. How should these precious resources be governed, and how should the benefits and burdens they generate be shared? Justice and Natural Resources provides a systematic theory of natural resource (...) justice. It argues that we should use the benefits and burdens flowing from these resources to promote greater equality across the world, and share governance over many important resources. At the same time, the book takes seriously the ways in which particular resources can matter in peoples lives. It provides invaluable guidance on a series of pressing issues, including the scope of state resource rights, the claims of indigenous communities, rights over ocean resources, the burdens of conservation, and the challenges of climate change and transnational resource governance. It will be required reading for anyone interested in natural resource governance, climate politics, and global justice. (shrink)

This book takes concepts developed by researchers in theoretical computer science and adapts and applies them to the study of natural language meaning. Summarizing over a decade of research, Chris Barker and Chung-chieh Shan put forward the Continuation Hypothesis: that the meaning of a natural language expression can depend on its own continuation.

Pritchard and Vaesen have recently argued that robust virtue epistemology does not square with the extended cognition thesis that has enjoyed an increasing degree of popularity in recent philosophy of mind. This paper shows that their arguments fail. The relevant cases of extended cognition pose no new problem for robust virtue epistemology. It is shown that Pritchard’s and Vaesen’s cases can be dealt with in familiar ways by a number of virtue theories of knowledge.

States claim the right to choose who can come to their country. They put up barriers and expose migrants to deadly journeys. Those who survive are labelled ‘illegal’ and find themselves vulnerable and unrepresented. The international state system advantages the lucky few born in rich countries and locks others into poor and often repressive ones. In this book, Christopher Bertram skilfully weaves a lucid exposition of the debates in political philosophy with original insights to argue that migration controls must be (...) justifiable to everyone, including would-be and actual immigrants. Until justice prevails, states have no credible right to exclude and no-one is obliged to obey their immigration rules. Bertram’s analysis powerfully cuts through the fog of political rhetoric that obscures this controversial topic. It will be essential reading for anyone interested in the politics and ethics of migration. (shrink)

When in the business of offering an account of the epistemic normativity of belief, one is faced with the following dilemma: strongly externalist norms fail to account for the intuition of justification in radical deception scenarios, while milder norms are incapable to explain what is epistemically wrong with false beliefs. This paper has two main aims; we first look at one way out of the dilemma, defended by Timothy Williamson and Clayton Littlejohn, and argue that it fails. Second, we identify (...) what we take to be the problematic assumption that underlies their account and offer an alternative way out. We put forth a knowledge-first friendly normative framework for belief which grants justification to radically deceived subjects while at the same time acknowledging that their false beliefs are not epistemically good beliefs.

According to what Williamson labels ‘the C account of assertion’, there is one and only one rule that is constitutive of assertion. This rule, the so-called ‘C Rule’, states that one must assert p only if p has property C. This paper argues that the C account of assertion is incompatible with any live proposal for C in the literature.

This paper explores the application of hinge epistemology to deep disagreement. Hinge epistemology holds that there is a class of commitments—hinge commitments—which play a fundamental role in the structure of belief and rational evaluation: they are the most basic general ‘presuppositions’ of our world views which make it possible for us to evaluate certain beliefs or doubts as rational. Deep disagreements seem to crucially involve disagreements over such fundamental commitments. In this paper, I consider pessimism about deep disagreement, the thesis (...) that such disagreements are rationally irresolvable, and ask whether the Wittgensteinian account of deep disagreement—according to which such disagreements are disagreements over hinge commitments—provides adequate support for pessimism. I argue that the answer to this question depends on what hinge commitments are and what our epistemic relation to them is supposed to be. I argue for two core claims. First, that non-epistemic theories of hinge commitments provide adequate support for pessimism. Nevertheless, such theories have highly implausible consequences in the context of deep disagreement. Secondly, at least one epistemic theory of hinge commitments, the entitlement theory, permits optimism about such disagreements. As such, while hinge epistemology is mainly pessimistic about deep disagreement, it doesn’t have to be. (shrink)

An Introduction to Philosophical Methods is the first book to survey the various methods that philosophers use to support their views.

While eminently student-friendly, the book makes an important contribution to the debate regarding the acceptability of the various philosophical methods, and (...) so it will also be of interest to more experienced philosophers.

This paper develops an account of trustworthy AI. Its central idea is that whether AIs are trustworthy is a matter of whether they live up to their function-based obligations. We argue that this account serves to advance the literature in a couple of important ways. First, it serves to provide a rationale for why a range of properties that are widely assumed in the scientific literature, as well as in policy, to be required of trustworthy AI, such as safety, justice, (...) and explainability, are properties (often) instantiated by trustworthy AI. Second, we connect the discussion on trustworthy AI in policy, industry, and the sciences with the philosophical discussion of trustworthiness. We argue that extant accounts of trustworthiness in the philosophy literature cannot make proper sense of trustworthy AI and that our account compares favourably with its competitors on this front.

The second edition of Doing Ethics in Media continues its mission of providing an accessible but comprehensive introduction to media ethics, with a theoretical grounding in moral philosophy, to help students think clearly and systematically about dilemmas in the rapidly changing media environment. Each chapter highlights specific considerations, cases, and practical applications for the fields of journalism, advertising, digital media, entertainment, public relations, and social media. Six fundamental decision-making questions - the "5Ws and H" around which the book is organized (...) - provide a path for students to articulate the issues; understand applicable law and ethics codes; consider the needs of stakeholders; work through conflicting values; integrate philosophic principles; and pose a "test of publicity." Students are challenged to be active ethical thinkers through the authors' reader-friendly style and use of critical early-career examples. While most people will change careers several times during their lives, all of us are life-long media consumers, and Doing Ethics in Media prepares readers for that task. Doing Ethics in Media is aimed at undergraduate and graduate students studying media ethics in mass media, journalism, and media studies. It also serves students in rhetoric, popular culture, communication studies, and interdisciplinary social sciences. The book's companion website-doingethicsin.media, or www.doingmediaethics.com-provides continuously updated real-world media ethics examples and collections of essays from experts and students. The site also hosts ancillary materials for students and for instructors, including a test bank and instructor's manual. (shrink)

Some disagreements concern our most fundamental beliefs, principles, values, or worldviews, such as those about the existence of God, society and politics, or the trustworthiness of science. These are ‘deep disagreements’. But what exactly are deep disagreements? This paper critically overviews theories of deep disagreement. It does three things. First, it explains the differences between deep and other kinds of disagreement, including peer, persistent, and widespread disagreement. Second, it critically overviews two mainstream theories of deep disagreement, the Wittgensteinian account and (...) the Fundamental Epistemic Principle account, before introducing a Hybrid account. Finally, it explores the notion that deep disagreements can be deeper than others. (shrink)

In a recent exchange, Vaesen and Kelp have argued over whether cases of extended cognition pose a problem for robust virtue epistemology.

Philosophers often treat racist and sexist slurs as a special sort of puzzle. What is the difference between a slur and its correlates? In attempting to answer this question, a second distinction has been overlooked: that between slurs and insults. What makes a term count as a slur? This is not an unnecessary taxonomical question as long as ableist terms such as ‘moron’ are dismissed as mere insults. Attempts to resolve the insult/slur distinction by considering the communicative content of slurs (...) are not promising. A better solution is offered by speech act theory, and this paper develops a novel way to describe ordinary slurring utterances as oppressive speech acts. This can both explain the difference between slurs and insults, and challenge the dismissal of ableist terms. (shrink)

The doctrine of permanent sovereignty over natural resources is a hugely consequential one in the contemporary world, appearing to grant nation-states both jurisdiction-type rights and rights of ownership over the resources to be found in their territories. But the normative justification for that doctrine is far from clear. This article elucidates the best arguments that might be made for permanent sovereignty, including claims from national improvement of or attachment to resources, as well as functionalist claims linking resource rights to key (...) state functions. But it also shows that these defences are insufficient to justify permanent sovereignty and that in many cases they actually count against it as a practice. They turn out to be compatible, furthermore, with the dispersal of resource rights away from the nation-state which global justice appears to demand. (shrink)
