When performing an action of a certain kind, an agent typically has se- veral reasons for doing so. I shall borrow Davidson’s term and call these rationalising reasons (Davidson 1963, 3). These are reasons that allow us to understand what the agent regarded as favourable features of such an action. (There will also be reasons against acting, expressing unfavour- able features of such an action, from the agent’s point of view.) I shall say that R is a rationalising reason (...) of agent X’s for K-ing iff R consists of (i) a desire of X’s to L and (ii) a belief of X’s that K-ing promotes L-ing (to be discussed shortly). It is frequently said that when an agent X is K-ing and has several rationalising reasons for K-ing, not all of those reasons are reasons for which X is K-ing, that motivate X’s K-ing, or that explain X’s K-ing. In this paper I challenge this view. (shrink)
