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.

A Virtue Epistemology presents a new approach to some of the oldest and most gripping problems of philosophy, those of knowledge and scepticism. Ernest Sosa argues for two levels of knowledge, the animal and the reflective, each viewed as a distinctive human accomplishment. By adopting a kind of virtue epistemology in line with the tradition found in Aristotle, Aquinas, Reid, and especially Descartes, he presents an account of knowledge which can be used to shed light on different varieties of scepticism, (...) the nature and status of intuitions, and epistemic normativity.

§1 To many in or on the edges of the Academy, ”Relativism” is a word with overtones of sinister iconoclasm, representing a kind of intellectual and ethical free-for-all in which the traditional investigative virtues of clarity, rigour, objectivity, consistency and the unbiased pursuit of truth are dismissed as illusory and the great scientific constructions of the last two hundred years, together with our deepest moral convictions, rated merely as ‘our way of seeing’ the world, more elaborate and organised but otherwise (...) on all fours with the cosmology and customs of primitive tribes. In his short book, Paul Boghossian aims to address, and to expose as bankrupt, the idea that there is even a coherent, let alone defensible philosophical stance about truth and knowledge that can underwrite these ‘pluralist’, or ‘postmodernist’ tendencies. But since it is crucial to his project that his style of discussion make it available to non-specialists, much of the recent more technical, less emotional debate within analytical philosophy about relativism’s renaissance as a particular form of semantic theory is passed over unmentioned. Part of my aim in what follows is to illustrate how Boghossian's discussion connects quite straightforwardly with relativism in its contemporary analytical philosophical livery—what I have elsewhere called New Age relativism1— and how some of his critical arguments may be presented in that setting. My main contentions will be, first, that when relativism about epistemic justification, and about morals, are couched in the currently canonical sort of form, they still remain in range of artillery that Boghossian positions in chapter 6 of his book; second, that there is evasive action that they can..

Abstract: Some proponents of “experimental philosophy” criticize philosophers' use of thought experiments on the basis of evidence that the verdicts vary with truth-independent factors. However, their data concern the verdicts of philosophically untrained subjects. According to the expertise defence, what matters are the verdicts of trained philosophers, who are more likely to pay careful attention to the details of the scenario and track their relevance. In a recent article, Jonathan M. Weinberg and others reply to the expertise defence that there (...) is no evidence for such expertise. They now receive a reply in this article, which argues that they have misconstrued the dialectical situation. Since they have produced no evidence that philosophical training is less efficacious for thought experimentation than for other cognitive tasks for which they acknowledge that it produces genuine expertise, such as informal argumentation, they have produced no evidence for treating the former more sceptically than the latter.

Sometimes, we think of belief as a phenomenon that comes in degrees – that is, in the many different levels of confidence that a thinker might have in various different propositions. Sometimes, we think of belief as a simple two-place relation that holds between a thinker and a proposition – that is, as what I shall here call "outright belief".

I consider the problem of how to derive what an agent believes from their credence function and utility function. I argue the best solution of this problem is pragmatic, i.e. it is sensitive to the kinds of choices actually facing the agent. I further argue that this explains why our notion of justified belief appears to be pragmatic, as is argued e.g. by Fantl and McGrath. The notion of epistemic justification is not really a pragmatic notion, but it is being (...) applied to a pragmatically defined concept, i.e. belief. (shrink)

Knowledge sets the standard for appropriate assertion and recent evidence suggests that it might also set the standard for appropriate belief and decision‐making. Governments spend hundreds of millions of dollars to support the creation, transfer, and mobilization of knowledge. Philosophers have created a dizzying array of Gettier case thought experiments. In doing so, many have been guilty of experimenter bias. This includes some original players who helped set the agenda for decades to come. Cognitive scientists recently began seriously investigating knowledge (...) judgments. The study of Gettier cases was motivated by work in psychology showing important cultural differences in reasoning styles and moral judgments. The nominal category Gettier case includes a variety of cases with radical structural differences that are extremely important in both theory and ordinary practice, so important as to render the nominal category, as the authors have inherited it, utterly useless.

Jonas Olson writes that "a plausible moral error theory must be an error theory about all irreducible normativity". I agree. But unlike Olson, I think we cannot believe this error theory. I first argue that Olson should say that reasons for belief are irreducibly normative. I then argue that if reasons for belief are irreducibly normative, we cannot believe an error theory about all irreducible normativity. I then explain why I think Olson's objections to this argument fail. I end by (...) showing that Olson cannot defend his view as a partly revisionary alternative to an error theory about all irreducible normativity. (shrink)

According to the error theory, normative judgements are beliefs that ascribe normative properties, even though such properties do not exist. In this paper, I argue that we cannot believe the error theory, and that this means that there is no reason for us to believe this theory. It may be thought that this is a problem for the error theory, but I argue that it is not. Instead, I argue, our inability to believe the error theory undermines many objections that (...) have been made to this theory. (shrink)

Frank Jackson has argued that, given plausible claims about supervenience, descriptive predicates and property identity, there are no irreducibly normative properties. Philosophers who think that there are such properties have made several objections to this argument. In this paper, I argue that all of these objections fail. I conclude that Jackson's argument shows that there are no irreducibly normative properties.

In this paper we propose to argue for two claims. The first is that a sizeable group of epistemological projects – a group which includes much of what has been done in epistemology in the analytic tradition – would be seriously undermined if one or more of a cluster of empirical hypotheses about epistemic intuitions turns out to be true. The basis for this claim will be set out in Section 2. The second claim is that, while the jury is (...) still out, there is now a substantial body of evidence suggesting that some of those empirical hypotheses are true. Much of this evidence derives from an ongoing series of experimental studies of epistemic intuitions that we have been conducting. A preliminary report on these studies will be presented in Section 3. In light of these studies, we think it is incumbent on those who pursue the epistemological projects in question to either explain why the truth of the hypotheses does not undermine their projects, or to say why, in light of the evidence we will present, they nonetheless assume that the hypotheses are false. In Section 4, which is devoted to Objections and Replies, we’ll consider some of the ways in which defenders of the projects we are criticizing might reply to our challenge. Our goal, in all of this, is not to offer a conclusive argument demonstrating that the epistemological projects we will be criticizing are untenable. Rather, our aim is to shift the burden of argument. (shrink)

According to an increasingly popular epistemological view, people need outright beliefs in addition to credences to simplify their reasoning. Outright beliefs simplify reasoning by allowing thinkers to ignore small error probabilities. What is outright believed can change between contexts. It has been claimed that thinkers manage shifts in their outright beliefs and credences across contexts by an updating procedure resembling conditionalization, which I call pseudo-conditionalization (PC). But conditionalization is notoriously complicated. The claim that thinkers manage their beliefs via PC is (...) thus in tension with the view that the function of beliefs is to simplify our reasoning. I propose to resolve this puzzle by rejecting the view that thinkers employ PC. Based on this solution, I furthermore argue for a descriptive and a normative claim. The descriptive claim is that the available strategies for managing beliefs and credences across contexts that are compatible with the simplifying function of outright beliefs can generate synchronic and diachronic incoherence in a thinker’s attitudes. Moreover, I argue that the view of outright belief as a simplifying heuristic is incompatible with the view that there are ideal norms of coherence or consistency governing outright beliefs that are too complicated for human thinkers to comply with.

An important book by the world's most eminent epistemologist. In Epistemic Explanations Sosa develops an improved virtue epistemology and uses it to explain several epistemic phenomena.

In this concise book, one of the world's leading epistemologists provides a sophisticated, revisionist introduction to the problem of knowledge in Western philosophy. Modern and contemporary accounts of epistemology tend to focus on limited questions of knowledge and skepticism, such as how we can know the external world, other minds, the past through memory, the future through induction, or the world’s depth and structure through inference. This book steps back for a better view of the more general issues posed by (...) the ancient Greek Pyrrhonists. Returning to and illuminating this older, broader epistemological tradition, Ernest Sosa develops an original account of the subject, giving it substance not with Cartesian theology but with science and common sense. -/- Descartes is a part of this ancient tradition, but he goes beyond it by considering not just whether knowledge is possible at all but also how we can properly attain it. In Cartesian epistemology, Sosa finds a virtue-theoretic account, one that he extends beyond the Cartesian context. Once epistemology is viewed in this light, many of its problems can be solved or fall away. -/- The result is an important reevaluation of epistemology that will be essential reading for students and teachers.

[This is a paper that was originally written in 2017 and doesn't represent Silva's current thinking about the relation between belief and degrees of confidence. See On Believing and Being Convinced for more.] Can there be knowledge and rational belief in the absence of a rational degree of confidence? Yes, and cases of "mistuned knowledge" demonstrate this. In this paper we leverage this normative possibility in support of advancing our understanding of the metaphysical relation between belief and credence. It is (...) generally assumed that a Lockean metaphysics of belief that reduces outright belief to degrees of confidence would immediately effect a unification of coarse-grained epistemology of belief with fine-grained epistemology of confidence. Scott Sturgeon has suggested that the unification is effected by understanding the relation between outright belief and confidence as an instance of the determinable-determinate relation. But determination of belief by confidence would not by itself yield the result that norms for confidence carry over to norms for outright belief unless belief and high confidence are token identical. We argue that this token-identity thesis is incompatible with the neglected phenomenon of “mistuned knowledge”—knowledge and rational belief in the absence of rational confidence. We contend that there are genuine cases of mistuned knowledge and that, therefore, epistemological unification must forego token identity of belief and high confidence. We show how partial epistemological unification can be secured given determination of outright belief by degrees of confidence even without token-identity. Finally, we suggest a direction for the pursuit of thoroughgoing epistemological unification. (shrink)

The Description for this book, The Analysis of Knowing: A Decade of Research, will be forthcoming.

In this paper I defend what I call the argument from epistemic reasons against the moral error theory. I argue that the moral error theory entails that there are no epistemic reasons for belief and that this is bad news for the moral error theory since, if there are no epistemic reasons for belief, no one knows anything. If no one knows anything, then no one knows that there is thought when they are thinking, and no one knows that they (...) do not know everything. And it could not be the case that we do not know that there is thought when we believe that there is thought and that we do not know that we do not know everything. I address several objections to the claim that the moral error theory entails that there are no epistemic reasons for belief. It might seem that arguing against the error theory on the grounds that it entails that no one knows anything is just providing a Moorean argument against the moral error theory. I show that even if my argument against the error theory is indeed a Moorean one, it avoids Streumer's, McPherson's and Olson's objections to previous Moorean arguments against the error theory and is a more powerful argument against the error theory than Moore's argument against external world skepticism is against external world skepticism.

In this paper, I do three things. First, I offer an overview of an anti- luck epistemology, as set out in my book, Epistemic Luck. Second, I attempt to meet some of the main criticisms that one might level against the key theses that I propose in this work. And finally, third, I sketch some of the ways in which the strategy of anti- luck epistemology can be developed in new directions.

A certain construal of the Gettier problem is offered, according to which this problem concerns the task of identifying the anti-luck condition on knowledge. A methodology for approaching this construal of the Gettier problem—anti-luck epistemology—is set out, and the utility of such a methodology is demonstrated. It is argued that a range of superficially distinct cases which are meant to pose problems for anti-luck epistemology are in fact related in significant ways. It is claimed that with these cases properly understood, (...) anti-luck epistemology is able to offer a suitable diagnosis of them which doesn’t threaten the necessity of the anti-luck condition for knowledge.

There was a long tradition in philosophy according to which good reasoning had to be deductively valid. However, that tradition began to be questioned in the 1960’s, and is now thoroughly discredited. What caused its downfall was the recognition that many familiar kinds of reasoning are not deductively valid, but clearly confer justification on their conclusions. Here are some simple examples.

Is there anything wrong with publishing philosophical work which one does not believe (publishing without belief, henceforth referred to as ‘PWB’)? I argue that there is not: the practice isn’t intrinsically wrong, nor is there a compelling consequentialist argument against it. Therefore, the philosophical community should neither proscribe nor sanction it. The paper proceeds as follows. First, I’ll clarify and motivate the problem, using both hypothetical examples and a recent real-world case. Next, I’ll look at arguments that there is something (...) wrong with PWB, and show that none is sound. Then, I’ll give some reasons for thinking a norm against PWB is detrimental to the profession. Do I believe these arguments? If I’m right, it shouldn’t matter. (shrink)

This article is a response to critical articles by Daan Evers, Bart Streumer, and Teemu Toppinen on my book Moral Error Theory: History, Critique, Defence. I will be concerned with four main topics. I shall first try to illuminate the claim that moral facts are queer, and its role in the argument for moral error theory. In section 2, I discuss the relative merits of moral error theory and moral contextualism. In section 3, I explain why I still find the (...) queerness argument concerning supervenience an unpromising argument against non-naturalistic moral realism. In section 4, finally, I reconsider the question whether I, or anyone, can believe the error theory. (shrink)

This paper explains and defends a belief-first view of the relationship between belief and credence. On this view, credences are a species of beliefs, and the degree of credence is determined by the content of what is believed. We begin by developing what we take to be the most plausible belief-first view. Then, we offer several arguments for it. Finally, we show how it can resist objections that have been raised to belief-first views. We conclude that the belief-first view is (...) more plausible than many have previously supposed. (shrink)

Experimental philosophers have challenged friends of the expertise defense to show that the intuitive judgments of professional philosophers are different from the intuitive judgments of nonphilosophers, and the intuitive judgments of professional philosophers are better than the intuitive judgments of nonphilosophers, in ways that are relevant to the truth or falsity of such judgments. Friends of the expertise defense have responded by arguing that the burden of proof lies with experimental philosophers. This article sketches three arguments which show that both (...) and are probably false. If its arguments are cogent, then shifting the burden of proof is a futile move, since philosophical training makes no difference so far as making intuitive judgments in response to hypothetical cases is concerned.

In defending his interest-relative account of knowledge in Knowledge and Practical Interests (2005), Jason Stanley relies heavily on intuitions about several bank cases. We experimentally test the empirical claims that Stanley seems to make concerning our common-sense intuitions about these bank cases. Additionally, we test the empirical claims that Jonathan Schaffer seems to make in his critique of Stanley. We argue that our data impugn what both Stanley and Schaffer claim our intuitions about such cases are. To account for these (...) results, one must develop a better conception of the connection between a subject's interests and her body of knowledge than those offered by Stanley and Schaffer.

There seem to be topics on which people can disagree without fault. For example, you and I might disagree on whether Picasso was a better artist than Matisse, without either of us being at fault. Is this a genuine possibility or just apparent? In this paper I pursue two aims: I want to provide a systematic map of available responses to this question. Simultaneously, I want to assess these responses. I start by introducing and defining the notion of a faultless (...) disagreement. Then I present a simple argument to the conclusion that faultless disagreement is not possible. Those who accept the argument have to explain away apparent cases of faultless disagreement. Those who want to maintain the possibility of faultless disagreement must deny one of the argument's premisses. The position I want to promote belongs to the latter category and is a form of genuine relativism. (shrink)

In this article, we present evidence that in four different cultural groups that speak quite different languages there are cases of justified true beliefs that are not judged to be cases of knowledge. We hypothesize that this intuitive judgment, which we call “the Gettier intuition,” may be a reflection of an underlying innate and universal core folk epistemology, and we highlight the philosophical significance of its universality.

As Paul Boghossian sees it, postmodernist relativists and constructivists are paralyzed by a “fear of knowledge.” For example, they lack the courage to say, in the face of the Lakotas’ claim that their ancestors came from inside the earth, that it is a matter of known fact that their ancestors came across the Bering Strait. To avoid this, they accept the nonconfrontational view Boghossian calls..

Recent third person approaches to thought experiments and conceptual analysis through the method of surveys are motivated by and motivate skepticism about the traditional first person method. I argue that such surveys give no good ground for skepticism, that they have some utility, but that they do not represent a fundamentally new way of doing philosophy, that they are liable to considerable methodological difficulties, and that they cannot be substituted for the first person method, since the a priori knowledge which (...) is our object in conceptual analysis can be acquired only from the first person standpoint.

Bart Streumer argues that it is not possible for us to believe the error theory, where by ‘error theory’ he means the claim that our normative beliefs are committed to the existence of normative properties even though such properties do not exist. In this paper, we argue that it is indeed possible to believe the error theory. First, we suggest a critical improvement to Streumer’s argument. As it stands, one crucial premise of that argument—that we cannot have a belief while (...) believing that there is no reason to have it—is implausibly strong. We argue that for his purposes, Streumer’s argument only requires a weaker premise, namely that we cannot rationally have a belief while believing that there is no reason to have it. Secondly, we go on to refute the improved argument. Even in its weaker form, Streumer’s argument is either invalid or the crucial premise should be rejected. (shrink)

In disputes about conceptual analysis, each side typically appeals to pre-theoretical 'intuitions' about particular cases. Recently, many naturalistically oriented philosophers have suggested that these appeals should be understood as empirical hypotheses about what people would say when presented with descriptions of situations, and have consequently conducted surveys on non-specialists. I argue that this philosophical research programme, a key branch of what is known as 'experimental philosophy', rests on mistaken assumptions about the relation between people's concepts and their linguistic behaviour. The (...) conceptual claims that philosophers make imply predictions about the folk's responses only under certain demanding, counterfactual conditions. Because of the nature of these conditions, the claims cannot be tested with methods of positivist social science. We are, however, entitled to appeal to intuitions about folk concepts in virtue of possessing implicit normative knowledge acquired through reflective participation in everyday linguistic practices.

Epistemic expressivism is the view that epistemic appraisals are basically non-factual valuations. In this paper I consider recent objections pressed by Terrence Cuneo, Michael Lynch and Jonathan Kvanvig to the effect that whatever the problems of expressivism in general, epistemic expressivism faces certain fatal objections due to the fact that the view is applied to the epistemic domain. The most important of these objections state, roughly, that because of the very content of the doctrine, epistemic expressivism cannot be coherently asserted (...) or argued for. Thus, epistemic expressivism is, as I shall say, dialectically incoherent. Another way to put the objection is this: there is no cogent perspective in which epistemic expressivism can be asserted or argued for. Since these arguments all trade on the idea of a perspective in which epistemic expressivism is to be asserted, I shall, following Terence Cuneo's terminology, refer to the arguments as the perspective objections (Cuneo 2007, 170). I argue that the perspective objections fail. Whatever serious objections there might be to epistemic expressivism, the charge that the view is dialectically incoherent is not one of them. (shrink)

forthcoming in Philosophy Compass. This is a paper which aims both to survey the field and do some work at its cutting edge.

Standard characterizations of virtue epistemology divide the field into two camps: virtue reliabilism and virtue responsibilism. Virtue reliabilists think of intellectual virtues as reliable cognitive faculties or abilities, while virtue responsibilists conceive of them as good intellectual character traits. I argue that responsibilist character virtues sometimes satisfy the conditions of a reliabilist conception of intellectual virtue, and that consequently virtue reliabilists, and reliabilists in general, must pay closer attention to matters of intellectual character. This leads to several new questions and (...) (...) challenges for any reliabilist epistemology. (shrink)

Sometimes epistemologists theorize about belief, a tripartite attitude on which one can believe, withhold belief, or disbelieve a proposition. In other cases, epistemologists theorize about credence, a fine-grained attitude that represents one’s subjective probability or confidence level toward a proposition. How do these two attitudes relate to each other? This article explores the relationship between belief and credence in two categories: descriptive and normative. It then explains the broader significance of the belief-credence connection and concludes with general lessons from the (...) debate thus far. (shrink)
