Abstract

Gregory Kavka’s toxin puzzle has spawned a lively literature about the nature of intention and of rational intention in particular. This paper is largely a critique of a pair of recent responses to the puzzle that focus on the connection between rationally forming an intention to A and rationally A-ing, one by David Gauthier and the other by Edward McClennen. It also critically assesses the two main morals Kavka takes reflection on the puzzle to support, morals about the nature of intention and the consequences of a divergence between “reasons for intending and reasons for acting.
