In this paper, we claim that, if you justifiably believe that you ought to perform some act, it follows that you ought to perform that act. In the first half, we argue for this claim by reflection on what makes for correct reasoning from beliefs about what you ought to do. In the second half, we consider a number of objections to this argument and its conclusion. In doing so, we arrive at another argument for the view that justified beliefs about what you ought to do must be true, based in part on the idea that the epistemic and practical domains are uniform, in a sense we spell out. We conclude by sketching possible implications of our discussion for the debates over what is wrong with akrasia and pragmatic encroachment on justified belief and knowledge.

In days past, epistemologists expended a good deal of effort trying to analyze the basing relation—the relation between a belief and its basis. No satisfying account was offered, and the project was largely abandoned. Younger epistemologists, however, have begun to yearn for an adequate theory of basing. I aim to deliver one. After establishing some data and arguing that traditional accounts of basing are unsatisfying, I introduce a novel theory of the basing relation: the dispositional theory. It begins with the pedestrian observation that beliefs stand or fall with their bases. The theory I offer is an elucidation and refinement of this thought.

In this paper, I begin by defending permissivism: the claim that, sometimes, there is more than one way to rationally respond to a given body of evidence. Then I argue that, if we accept permissivism, certain worries that arise as a result of learning that our beliefs were caused by the communities we grew up in, the schools we went to, or other irrelevant influences dissipate. The basic strategy is as follows: First, I try to pinpoint what makes irrelevant influences worrying and I come up with two candidate principles. I then argue that one principle should be rejected because it is inconsistent with permissivism. The principle we should accept implies that it is sometimes rational to maintain our beliefs, even upon learning that they were caused by irrelevant influences.

This paper compares two alternative explanations of pragmatic encroachment on knowledge (i.e., the claim that whether an agent knows that p can depend on pragmatic factors). After reviewing the evidence for such pragmatic encroachment, we ask how it is best explained, assuming it obtains. Several authors have recently argued that the best explanation is provided by a particular account of belief, which we call pragmatic credal reductivism. On this view, what it is for an agent to believe a proposition is for her credence in this proposition to be above a certain threshold, a threshold that varies depending on pragmatic factors. We show that while this account of belief can provide an elegant explanation of pragmatic encroachment on knowledge, it is not alone in doing so, for an alternative account of belief, which we call the reasoning disposition account, can do so as well. And the latter account, we argue, is far more plausible than pragmatic credal reductivism, since it accords far better with a number of claims about belief that are very hard to deny.

Vice epistemology is the philosophical study of the nature, identity, and epistemological significance of intellectual vices. Such vices include gullibility, dogmatism, prejudice, closed-mindedness, and negligence. These are intellectual character vices, that is, intellectual vices that are also character traits. I ask how the notion of an intellectual character vice should be understood, whether such vices exist, and how they might be epistemologically significant. The proposal is that intellectual character vices are intellectual character traits that impede effective and responsible inquiry. I argue that situationist critiques of virtue epistemology pose no significant threat to this proposal. Studies by social psychologists of belief in conspiracy theories suggest that it is sometimes appropriate to explain questionable beliefs by reference to intellectual character vices. Neither 'regulative' nor 'analytic' epistemology has any good reason to question the epistemological significance of such vices.

The importance of the Non-Akrasia Constraint is brought out by recent literature on \"higher-order evidence\"--evidence about what evidence one has, or what one's evidence supports. Much of this debate has focused on the question of what to believe when one becomes rationally highly confident that P on the basis of some evidence, E, and then receives further (misleading) evidence to the effect that E does not support P. Although there is disagreement as to whether this new evidence should cause one to reduce confidence in P, the major positions that have been defended thus far in the higher-order evidence debate agree that ideally rational agents should respect the Non-Akrasia Constraint.

When discussing knowledge, two relations are of interest: justified doxastic accessibility S (for all the agent is justified in believing in x, she is in y) and justification equivalence E (the agent would have in y exactly the same justified beliefs that she has in x). Speaking of compatibility with the agent's justified beliefs is potentially ambiguous: either of the two relations S or E can be meant. I discuss the possibility of identifying the relation of epistemic accessibility R (for all the agent knows in x, she is in y) with the union of S and E. Neither Gettier's examples nor the 'fake barn' cases contradict this identification. However, the proposal leads to justification equivalent scenarios being symmetric with respect to knowledge: we cannot know a true proposition in a scenario if it is false in a justification equivalent scenario. This analysis may appear to render non-trivial knowledge impossible. This conclusion follows if the extra premise is granted that for all relevant true propositions there is a justification equivalent scenario in which the proposition is false. I provide a meaning-theoretic argument against this premise. I conclude by pointing out problems that would ensue from giving up the proposed connection between S, E and R and allowing asymmetry of justification equivalent scenarios relative to knowledge.

Pritchard argues that there's an adequate theory of knowledge available which fulfills the remit of the analytical project. Central to his proposal is the idea that people need to reconsider anti-luck intuition and ability intuition, which govern their thinking about knowledge, specifically, their thinking regarding what turns true belief into knowledge. He also argues that this conception of how these two master intuitions about knowledge are related to each other is fundamentally flawed. In particular, he claims that these two intuitions in fact impose independent epistemic demands on the theory of knowledge, and that it's only once one recognizes this fact that one can offer a successful resolution of the analytical project. He further explores anti-luck epistemology and virtue epistemology, two popular contemporary approaches to the analytical project which each take one of these intuitions about knowledge as central to their approach.

There are currently two robust traditions in philosophy dealing with doxastic attitudes: the tradition that is concerned primarily with all-or-nothing belief, and the tradition that is concerned primarily with degree of belief or credence. This paper concerns the relationship between belief and credence for a rational agent, and is directed at those who may have hoped that the notion of belief can either be reduced to credence or eliminated altogether when characterizing the norms governing ideally rational agents. It presents a puzzle which lends support to two theses. First, that there is no formal reduction of a rational agent's beliefs to her credences, because belief and credence are each responsive to different features of a body of evidence. Second, that if our traditional understanding of our practices of holding each other responsible is correct, then belief has a distinctive role to play, even for ideally rational agents, that cannot be played by credence. The question of which avenues remain for the credence-only theorist is considered.
