This paper addresses the question: ‘what makes reasons sufficient?’ and offers the answer, ‘being at least as weighty as the reasons for the alternatives’. The paper starts by introducing some of the reasons why sufficiency has seemed difficult to understand, particularly in epistemology, and some circumstantial evidence that this has contributed to more general problems in the epistemological literature. It then introduces the positive account of sufficiency, and explains how this captures sufficiency in both the practical and epistemic domains. Finally, (...) the paper shows how once we understand the nature of sufficiency, it is easy to predict the full variety of ways in which rationality – both of action and of belief – can be defeated.

Several authors have recently endorsed the thesis that there is what has been called pragmatic encroachment on knowledge—in other words, that two people who are in the same situation with respect to truth-related factors may differ in whether they know something, due to a difference in their practical circumstances. This paper aims not to defend this thesis, but to explore how it could be true. What I aim to do, is to show how practical factors could play a role in (...) defeating knowledge by defeating epistemic rationality—the very kind of rationality that is entailed by knowledge, and in which Pascalian considerations do not play any role—even though epistemic rationality consists in having adequate evidence.

One recurrent objection to the idea that the right kind of reasons for or against an attitude are object-given reasons for or against that attitude is that object-given reasons for or against belief and disbelief are incapable of explaining certain features of epistemic normativity. Prohibitive balancing, the behaviour of bare statistical evidence, information about future or easily available evidence, pragmatic and moral encroachment, as well as higher-order defeaters, are all said to be inexplicable in terms of those object-given reasons. In (...) this paper, I provide a rebuttal to all these challenges by drawing attention to the object-given reasons for and against the third doxastic state, namely the suspension of judgement. First, I introduce an original picture of how suspension relates to belief and disbelief – as ways of being decided – which yields a novel weighing model of the corresponding reasons. Second, I demonstrate that this new take on doxastic deliberation can accommodate all five features of epistemic normativity. Finally, I extend the weighing model to cover practical deliberation and the suspension of intentions. The resulting theory provides an explanation of why epistemic and practical normativity differ in certain respects in terms of a significant difference between doxastic and conative suspension.

Epistemic nihilism for inquiry is the claim that there are no epistemic norms of inquiry. Epistemic nihilism was once the received stance towards inquiry, and I argue that it should be taken seriously again. My argument is that the same considerations which led us away from epistemic nihilism in the case of belief not only cannot refute epistemic nihilism for inquiry, but in fact may well support it. These include the argument from non-existence that there are no non-epistemic reasons for (...) belief; the linguistic argument that epistemic norms of belief are needed to capture the semantics of ordinary epistemic talk; and the argument from theoretical roles that epistemic norms are needed to play key theoretical roles for rational belief. I conclude by sketching an alternative Gibbardian picture on which norms of inquiry are all-things-considered norms governing action. (shrink)

Philosophers have often noted a contrast between practical and theoretical reasons when it comes to cases involving equally balanced reasons. When there are strong practical reasons for A-ing, and equally strong practical reasons for some incompatible option, B-ing, the agent is permitted to make an arbitrary choice between them, having sufficient reason to A and sufficient reason to B. But when there is strong evidence for P and equally strong evidence for ~ P, one isn’t permitted to simply believe one (...) or the other. Instead, one must withhold belief, neither believing that P nor believing that ~ P. This paper examines what explains this contrast, focusing in particular on a proposal recently developed by Mark Schroeder across several papers. Schroeder aims to explain the contrast by an appeal to non-evidential, epistemic reasons against belief. But, I argue, it’s not clear exactly what those reasons are, nor how those reasons are to be weighed against evidential reasons. Despite these challenges, I argue that there are grounds for optimism that the contrast can be explained within the broad framework Schroeder provides, and I aim to provide resources to meet the aforementioned challenges.

A number of authors have defended permissivism by appealing to rational supererogation, the thought that some doxastic states might be rationally permissible even though there are other, more rational beliefs available. If this is correct, then there are situations that allow for multiple rational doxastic responses, even if some of those responses are rationally suboptimal. In this paper, I will argue that this is the wrong approach to defending permissivism—there are no doxastic states that are rationally supererogatory. By the lights (...) of contemporary linguistics, ‘rational’ is an absolute gradable adjective, and as such, can only be applied to things that satisfy the top of the scale of rationality. For this reason, it is not possible to believe what is rational while also failing to believe what is rationally optimal. (shrink)

According to the Book of Common Prayer, we have sinned against God “in thought, word, and deed.” In this paper I’ll explore one way of understanding what it might mean to sin against God in thought—the idea that we can at least potentially wrong God by what we believe. I will be interested in the philosophical tenability of this idea, and particularly in its potential consequences for the epistemology of religious belief and the problem of evil.

I clarify and defend the hypothesis that human belief formation is sensitive to social rewards and punishments, such that beliefs are sometimes formed based on unconscious expectations of their likely effects on other agents – agents who frequently reward us when we hold ungrounded beliefs and punish us when we hold reasonable ones. After clarifying this phenomenon and distinguishing it from other sources of bias in the psychological literature, I argue that the hypothesis is plausible on theoretical grounds and I (...) show how it illuminates and unifies a range of psychological phenomena, including confabulation and rationalisation, positive illusions, and identity-protective cognition.

This paper is about how epistemic and practical reasons for belief can be compared against one another when they conflict. It provides a model for determining what one ought to believe, all-things-considered, when there are conflicting epistemic and practical reasons. The model is meant to supplement a form of pluralism about doxastic normativity that I call ‘Inclusivism’. According to Inclusivism, both epistemic and practical considerations can provide genuine normative reasons for belief, and both types of consideration can contribute to metaphysically (...) determining what beliefs one ought, all-things-considered, to have.

This paper addresses the extent to which quotidian cognition is like scientific inference by focusing on Jerry Fodor's famous analogy. I specifically consider and rebut a recent attempt made by Tim Fuller and Richard Samuels to deny the usefulness of Fodor's analogy. In so doing, I reveal some subtleties of Fodor's arguments overlooked by Fuller and Samuels and others. Recognizing these subtleties provides a richer appreciation of the analogy, allowing us to gain better traction on the issue concerning the extent (...) to which everyday cognition is like scientific inference. In the end, I propose that quotidian cognition is indeed like scientific inference, but not precisely in the way Fodor claims it is. (shrink)

This paper sharpens the distinction between inferential and logcon arguments. Inferential arguments represent possible inferences, logcon ones need not. This distinction clarifies the roles that arguments play in accounting for the normativity of validity for inferential reasoning and in establishing the theoretical connection between validity and logical consequence. There are two related takeaways. First, the normativity of validity for inferential reasoning is grounded on the notion of an inferential argument. This will account for the use of validity to judge inference (...) in the face of well-known skepticism that a theory of validity has any special relevance to inferential reasoning. Second, a valid logcon argument needn't be an inferential argument. Accordingly, the normativity of validity for inferential reasoning doesn't require that every valid logcon argument be an inferential argument. The takeaways harmonize the use of validity to evaluate inferential reasoning with the use of the concept of logical consequence to characterize validity. (shrink)

What is the relation between entailment and reasons for belief? In this paper, I discuss several answers to this question, and I argue that these answers all face problems. I then propose the following answer: for all propositions p1,...,pn and q, if the conjunction of p1,..., and pn entails q, then there is a reason against a person's both believing that p1,..., and that pn and believing the negation of q. I argue that this answer avoids the problems that the (...) other answers to this question face, and that it does not face any other problems either. I end by showing what the relation between deductive logic, reasons for belief and reasoning is if this answer is correct. (shrink)

This paper reviews the largely psychological literature surrounding apparent failures of human rationality (sometimes referred to as 'the Rationality Wars') and locates it with respect to concepts and issues within more traditional epistemological inquiry. The goal is to bridge the gap between these two large and typically disconnected literatures – concerning rationality and the psychology of human reasoning, on the one hand, and epistemological theories of justified or rational belief, on the other – and to do so in such as (...) way as to expose interesting points of contact and convergence between them.
