I argue that the claim that epistemic ought is incommensurable is self-defeating. My argument, however, depends on the truth of the premise that there can be not only epistemic reasons for belief, but also non-epistemic (e.g., moral) reasons for belief. So I also provide some support for that claim.

To be a doxastic deontologist is to claim that there is such a thing as an ethics of belief (or of our doxastic attitudes in general). In other words, that we are subject to certain duties with respect to our doxastic attitudes, the non-compliance with which makes us blameworthy and that we should understand doxastic justification in terms of these duties. In this paper, I argue that these duties are our all things considered duties, and not our epistemic or moral duties, for example. I show how this has the surprising result that, if deontologism is a thesis about doxastic justification, it entails that there is no such thing as epistemic or moral justification for a belief that p. I then suggest why this result, though controversial, may have some salutary consequences: primarily that it helps us make some sense of an otherwise puzzling situation regarding doxastic dilemmas.

Abstract Conspiracy theories should be neither believed nor investigated - that is the conventional wisdom. I argue that it is sometimes permissible both to investigate and to believe. Hence this is a dispute in the ethics of belief. I defend epistemic “oughts” that apply in the first instance to belief-forming strategies that are partly under our control. But the beliefforming strategy of not believing conspiracy theories would be a political disaster and the epistemic equivalent of selfmutilation. I discuss several variations of this strategy, interpreting “conspiracy theory” in different ways but conclude that on all these readings, the conventional wisdom is deeply unwise.

Beliefs come in different strengths. What are the norms that govern these strengths of belief? Let an agent's belief function at a particular time be the function that assigns, to each of the propositions about which she has an opinion, the strength of her belief in that proposition at that time. Traditionally, philosophers have claimed that an agent's belief function at any time ought to be a probability function (Probabilism), and that she ought to update her belief function upon obtaining new evidence by conditionalizing on that evidence (Conditionalization). Until recently, the central arguments for these claims have been pragmatic. But these putative justifications fail to identify what is epistemically irrational about violating Probabilism or Conditionalization. A new approach, which I will call epistemic utility theory, attempts to remedy this. It treats beliefs as epistemic acts; and it appeals to the notion of an epistemic utility function, which measures of how epistemically valuable a particular belief function is for a particular way the world might be. It then formulates fundamental epistemic norms that are analogous to the fundamental practical norms that underlie decision theory. I survey the results obtained so far in this young research project, and present a sustained critique of certain assumptions that have been made by a number of philosophers working in this area.

The “ethics of belief” refers to a cluster of questions at the intersection of epistemology, philosophy of mind, psychology, and ethics. The central question in the debate is whether there are norms of some sort governing our habits of belief formation, belief maintenance, and belief relinquishment. Is it ever or always morally wrong (or epistemically irrational, or imprudent) to hold a belief on insufficient evidence? Is it ever or always morally right (or epistemically rational, or prudent) to believe on the basis of sufficient evidence, or to withhold belief in the perceived absence of it? Is it ever or always obligatory to seek out all available epistemic evidence for a belief? Are there some ways of obtaining evidence that are themselves immoral or imprudent?

From the dictum ought implies can , it has been argued that no account of belief's normativity can avoid the unpalatable result that, for unbelievable propositions such as "It is raining and nobody believes that it is raining", one ought not to believe them even if true. In this article, I argue that this move only succeeds on a faulty assumption about the conjunction of doxastic "oughts.".

In this paper, I explore the relationship between epistemic rationality and instrumental rationality, and I attempt to delineate their respective roles in typical instances of theoretical reasoning. My primary concern is with the instrumentalist conception of epistemic rationality: the view that epistemic rationality is simply a species of instrumental rationality, viz. instrumental rationality in the service of one's cognitive or epistemic goals. After sketching the relevance of the instrumentalist conception to debates over naturalism and 'the ethics of belief', I argue that, despite enjoying considerable popularity among both epistemologists and philosophers of science, it is ultimately indefensible. Having thus argued for the distinctness of epistemic and instrumental rationality, I attempt to clarify the role played by each in typical instances of theoretical reasoning. I suggest that being theoretically rational--that is, being proficient with respect to theoretical reasoning--is best construed as a hybrid virtue, inasmuch as it involves manifesting sensitivity to two very different kinds of reasons.

What should individuals do when their firmly held moral beliefs are prima facie inconsistent with their religious beliefs? In this article we outline several ways of posing such consistency challenges and offer a detailed taxonomy of the various responses available to someone facing a consistency challenge of this sort. Throughout the paper, our concerns are primarily pedagogical: how best to pose consistency challenges in the classroom, how to stimulate discussion of the various responses to them, and how to relate such consistency challenges to larger issues, such as whether Scripture is, in general, a reliable guide to truth.

According to one view about the rationality of belief, such rationality is ultimately nothing other than the rationality that one exhibits in taking the means to one’s ends. On this view, epistemic rationality is really a species or special case of instrumental rationality. In particular, epistemic rationality is instrumental rationality in the service of one’s distinctively cognitive or epistemic goals (perhaps: one’s goal of holding true rather than false beliefs). In my (2003), I dubbed this view the instrumentalist conception of epistemic rationality.

My primary purpose in this paper is to sketch a theory of doxastic oughts that achieves a satisfying middle ground between the extremes of rejecting epistemic deontology because one thinks beliefs are not within our direct voluntary control and rejecting doxastic involuntarism because one thinks that some doxastic oughts must be true. The key will be appreciating the obvious fact that not all true oughts require direct voluntary control. I will construct my account as an attempt to surpass other accounts (especially those due to Feldman and Kornblith) in this vein. The new idea (in a telegraphic slogan) is that doxastic oughts are what Sellars called “rules of criticism,” which are logically distinct from but also interestingly connected to “rules of action.” The distinction provides a way to understand the phrase ‘ought to believe’ which is consistent with both doxastic involuntarism and epistemic deontology; the connection provides a novel way to incorporate a believer’s epistemic community into our understanding of the scope of epistemic obligations.
