A central theme in social epistemology is that there are important and underappreciated phenomena involving social epistemic dependence—that is, epistemic dependence on other persons and on features of the broader social environment. Epistemologies that are inconsistent with this kind of dependence are labeled “individualist” and epistemologies that accommodate it are labeled “anti-individualist.” But how should the relevant notion of social epistemic dependence be understood? One important criterion for an adequate account is that it plausibly sorts epistemologies into the “individualist” and “anti-individualist” categories. For example, standard reductionism about testimonial justification and knowledge should count as individualist, and many trust theories should count as anti-individualist. This paper argues that several accounts of social epistemic dependence in the literature fail to pass this simple sorting test. An alternative account that does is proposed.

For over thirty years, Robert Audi has produced important work in ethics, epistemology, and the theory of action. This volume features thirteen new critical essays on Audi by a distinguished group of authors: Fred Adams, William Alston, Laurence BonJour, Roger Crisp, Elizabeth Fricker, Bernard Gert, Thomas Hurka, Hugh McCann, Al Mele, Walter Sinnott-Armstrong, Raimo Tuomela, Candace Vogler, and Timothy Williamson. Audi's introductory essay provides a thematic overview interconnecting his views in ethics, epistemology, and philosophy of action. The volume concludes with his comprehensive response essay that yields an illuminating dialog with all his critics and often extends his previous work.

Virtue epistemology is one of the most flourishing research programmes in contemporary epistemology. Its defining thesis is that properties of agents and groups are the primary focus of epistemic theorising. Within virtue epistemology two key strands can be distinguished: virtue reliabilism, which focuses on agent properties that are strongly truth-conducive, such as perceptual and inferential abilities of agents; and virtue responsibilism, which focuses on intellectual virtues in the sense of character traits of agents, such as open-mindedness and intellectual courage. This volume brings together ten new essays on virtue epistemology, with contributions to both of its key strands, written by leading authors in the field. It will advance the state of the art and provide readers with a valuable overview of what virtue epistemology has achieved.

This contribution to the topical collection presents an overview of my previous work in epistemology. Specifically, I review arguments for the claim that important skeptical arguments in the history of philosophy motivate externalism in epistemology. In effect, only externalist epistemologies can be anti-skeptical epistemologies. I also review motivations for adopting a virtue-theoretic account of epistemic normativity. Such an account, I argue, has considerable explanatory power regarding the nature, value and scope of knowledge. In addition, a virtue-theoretic account is tailor made for externalism. In effect, it shows how externalist epistemologies can also be normative epistemologies. Finally, I review arguments in favor of a general framework for understanding the epistemology of testimony, and, in particular, the transmission of knowledge. The framework motivates anti-reductionism in the epistemology of testimony, as well as the common anti-reductionist theme that trust can be epistemically significant, as opposed to merely practically significant. The framework, I argue, also weds nicely to a virtue-theoretic account of epistemic normativity, and in doing so answers an important objection to virtue epistemology—that the view is overly individualistic.

In ”Virtues in Epistemology,” John Greco presents and evaluates two main notions of intellectual virtue. The first concerns Ernest Sosa's development of this concept as a disposition to grasp truth and avoid falsehood. Greco contrasts this with moral models of intellectual virtue that include a motivational component in their definition, namely a desire for truth. Instead, Greco argues that a minimalist reliabilist account of intellectual virtue “in which the virtues are conceived as reliable cognitive abilities or powers,” can be illuminating in an account of knowledge. He sets out to support this on the grounds that his approach to intellectual virtue can adequately address three major problems on the theory of knowledge: Humean skepticism, the Gettier problem, and the problem of showing that knowledge is more valuable than mere true belief.

Section 1 of the paper reviews a family of “no good inference” arguments for skepticism about the external world, and a straightforward externalist reply. Section 2 reviews skeptical regress arguments, and another straightforward reply. Section 3 considers three objections to foundationalism that are inspired by Sellars’ critique of “the given” in “Empiricism and the Philosophy of Mind,” and argues that none of these is effective against the kind of “externalist foundationalism” defended in Sects. 1 and 2.

This paper explores a familiar skeptical problematic and considers some strategies for responding to it. Section 1 reconstructs and disambiguates the skeptical problematic, distinguishing between some importantly different lines of skeptical reasoning. Section 2 distinguishes two kinds of anti-skeptical strategy. “Cooperative strategies” accept the conditions on knowledge that are laid down by a target skeptical argument, and argue that those conditions can be satisfied in a relevant domain. “Critical strategies” respond to a skeptical argument by rejecting some condition on knowledge that the argument supposes. It is argued that critical strategies readily present themselves against the skeptical problematic once it is disambiguated as in Section 1. Section 3 looks at an interesting anti-skeptical strategy from Ram Neta and Duncan Pritchard on behalf of John McDowell. Here I argue that, initial appearances to the contrary, no plausible cooperative strategy is available to the internalist

Epistemic Evaluation aims to explore and apply a particular methodology in epistemology. The methodology is to consider the point or purpose of our epistemic evaluations, and to pursue epistemological theory in light of such matters. Call this purposeful epistemology. The idea is that considerations about the point and purpose of epistemic evaluation might fruitfully constrain epistemological theory and yield insights for epistemological reflection. Several contributions to this volume explicitly address this general methodology, or some version of it. Others focus on advancing some application of the methodology rather than on theorizing about it. The papers go on to explore the idea that purposes allow one to understand the conceptual demands on knowing, examine how purposeful epistemology might shed light on the debate between internalist and externalist epistemologies, and further develop the idea of purposeful epistemology.

John Greco’s Putting Skeptics in Their Place is an important book. Greco persuasively argues that the best skeptical arguments cannot be easily dismissed and should not be ignored. These arguments cannot be easily dismissed because they defend important conclusions and make no obvious mistake. The arguments should not be ignored because their proper analysis reveals much about central philosophical notions such as knowledge and evidence. While defending these conclusions Greco offers sophisticated metaepistemological and metaphilosophical reflections. Philosophers properly attending to the strongest skeptical arguments will, according to Greco, find themselves heading in the direction of a virtue-based version of reliabilism. Greco defends this general type of theory and outlines the major components of his preferred version of the theory. Greco stops short of defending a fully precise account of knowledge, but he offers a spirited defense of his claim that such a theory should fall somewhere in the family of virtue-based reliabilist theories, a type of theory that Greco calls “agent reliabilism.” Greco concludes with a brief discussion of moral and religious epistemology in which he applies some of the insights gained in his exploration and defense of agent reliabilism.

According to a popular objection, Hume assumes that only deductive inferences can generate knowledge and reasonable belief, and so Hume’s skepticism can be avoided by simply recognizing the role of inductive inferences in empirical matters. This paper offers an interpretation of Hume’s skepticism that avoids this objection. The resulting skeptical argument is a powerful one in the following sense: it is not at all obvious where the argument goes wrong, and responding to the argument forces us to adopt a substantive and even surprising position regarding the nature of knowledge and evidence. The main strategy is to draw a three way distinction among kinds of inferential support. Thus inferences can be deductive-supportive, inductive-supportive, or non-supportive. Hume does not assume that inductive inferences cannot generate knowledge or reasonable belief. Rather, he makes the more plausible assumption that non-supportive inferences cannot.

How do we transmit or distribute knowledge, as distinct from generating or producing it? In this book John Greco examines the interpersonal relations and social structures which enable and inhibit the sharing of knowledge within and across epistemic communities. Drawing on resources from moral theory, the philosophy of language, action theory and the cognitive sciences, he considers the role of interpersonal trust in transmitting knowledge, and argues that sharing knowledge involves a kind of shared agency similar to giving a gift or passing a ball. He also explains why transmitting knowledge is easy in some social contexts, such as those involving friendship or caregiving, but impossible in contexts characterized by suspicion and competition rather than by trust and cooperation. His book explores phenomena that have been undertheorized by traditional epistemology, and throws new light on existing problems in social epistemology and the epistemology of testimony.
