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.
