Kieran Setiya begins Reasons Without Rationalism by outlining and arguing for a schema in terms of which he thinks we best understand the nature of normative reasons for action. This is: " Reasons: The fact that p is a reason for A to ϕ just in case A has a collection of psychological states, C, such that the disposition to be moved to ϕ by C-and-the-belief-that-p is a good disposition of practical thought, and C contains no false beliefs. " As Setiya points out, Reasons contrasts with both the ‘advice’ model of normative reasons , which is the view that I myself prefer , and the ‘imitative’ model , preferred by the likes of McDowell .The intuitive idea behind Reasons should be clear enough. Insofar as normative reasons are normative, they are considerations that would justify an agent's acting in a certain way in certain circumstances: there is, thus, a justificatory dimension. But insofar as they are reasons, they are considerations on which the agent might act in those very circumstances: there is thus an explanatory dimension as well. Part of the attraction of Reasons is that it tells us why the considerations that are normative reasons have these two features: a consideration is a normative reason only if, given other things that the agent believes and desires, the disposition to be moved by a belief concerning that consideration is itself a good disposition of practical thought .Reasons is, however, just a schema. …

When we say that a subject has attitudes that she is rationally required to have, does that entail that she has those attitudes for reasons? In other words, is there a deep nexus between being rational and responding to reasons? Many have argued that there is. For example, Derek Parfit tells us that 'to be rational is to respond to reasons '. But I am not so sure. I begin by considering this question in the domain of theoretical rationality. The question in this domain is whether, when a subject has the beliefs that she is required to have by the norms of theoretical rationality, she is responding to reasons that there are for having those beliefs. Armed with a moderately clear answer to this question in the theoretical domain, I consider their relationship in the practical domain. When a subject has the desires that she is required to have by the norms of practical rationality, is she responding to reasons that there are for having those desires? Part of the interest of these questions lies in improving our understanding of reasons for action. I will say a little about this towards the end
