What should I do? What should I think? Traditionally, ethicists tackle the first question, while epistemologists tackle the second. Philosophers have tended to investigate the issue of what to do independently of the issue of what to think, that is, to do ethics independently of epistemology, and vice versa. This collection of new essays by leading philosophers focuses on a central concern of both epistemology and ethics: normativity. Normativity is a matter of what one should or may do or think, what one has reason or justification to do or to think, what it is right or wrong to do or to think, and so on. The volume is innovative in drawing together issues from epistemology and ethics and in exploring neglected connections between epistemic and practical normativity. It represents a burgeoning research programme in which epistemic and practical normativity are seen as two aspects of a single topic, deeply interdependent and raising parallel questions.

You are creditworthy for φ-ing only if φ-ing is the right thing to do. Famously though, further conditions are needed too – Kant’s shopkeeper did the right thing, but is not creditworthy for doing so. This case shows that creditworthiness requires that there be a certain kind of explanation of why you did the right thing. The reasons for which you act – your motivating reasons – must meet some further conditions. In this paper, I defend a new account of these conditions. On this account, creditworthiness requires that your motivating reasons be normative reasons, and that the principles from which you act match normative principles.

Many philosophers accept a response constraint on normative reasons: that p is a reason for you to φ only if you are able to φ for the reason that p. This constraint offers a natural way to cash out the familiar and intuitive thought that reasons must be able to guide us, and has been put to work as a premise in a range of influential arguments in ethics and epistemology. However, the constraint requires interpretation and faces putative counter-examples due to Julia Markovits, Mark Schroeder, and others. This paper develops and motivates an interpretation of the response constraint that avoids the putative counter-examples.

Evidentialism is the thesis that all reasons to believe p are evidence for p. Pragmatists hold that pragmatic considerations – incentives for believing – can also be reasons to believe. Nishi Shah, Thomas Kelly and others have argued for evidentialism on the grounds that incentives for belief fail a ‘reasoning constraint’ on reasons: roughly, reasons must be considerations we can reason from, but we cannot reason from incentives to belief. In the first half of the paper, I show that this argument fails: the claim that we cannot reason from incentives is either false or does not combine with the reasoning constraint to support evidentialism. However, the failure of this argument suggests an alternative route to evidentialism. Roughly, reasons must be premises of good reasoning, but it is not good reasoning to reason from incentives to belief. The second half of the paper develops and defends this argument for evidentialism.

According to Paul Boghossian and others, inference is subject to the taking condition: it necessarily involves the thinker taking his premises to support his conclusion, and drawing the conclusion because of that fact. Boghossian argues that this condition vindicates the idea that inference is an expression of agency, and that it has several other important implications too. However, we argue in this paper that the taking condition should be rejected. The condition gives rise to several serious prima facie problems and the reasons which have been offered in favour of it fail to convince.

The Wide-Scope approach to instrumental reason holds that the requirement to intend the necessary means to your ends should be understood as a requirement to either intend the means, or else not intend the end. In this paper I explain and defend a neglected version of this approach. I argue that three serious objections to Wide-Scope accounts turn on a certain assumption about the nature of the reasons that ground the Wide-Scope requirement. The version of the Wide-Scope approach defended here allows us to reject this assumption, and so defuse the objections.

The Wide-Scope view of instrumental reason holds that you should not intend an end without also intending what you believe to be the necessary means. This, the Wide-Scoper claims, provides the best account of why failing to intend the believed means to your end is a rational failing. But Wide-Scopers have struggled to meet a simple Explanatory Challenge: why shouldn't you intend an end without intending the necessary means? What reason is there not to do so? In the first half of this paper, I argue that the Wide-Scope view struggles to meet this challenge because it takes the principles of instrumental reason to have unlimited application—to apply to all agents, in all circumstances. I then go on to offer a new account of these principles. The new account is very much in the spirit of the Wide-Scope view, and shares its central advantages, but lacks its unlimited application. This view should, therefore, find the Explanatory Challenge more tractable. In the second half of the paper, I argue that this prediction is confirmed. If the requirements of instrumental reason apply only when a means is, or is believed to be, necessary for your end, then plausible independent claims, about reasons, rationality, and intentions, explain why failing to intend the necessary means to your ends is a rational failing.
