Reasons in Action

Abstract

Abstract The principal aim of this book is to analyse what it is to act for a reason in such a way that we intentionally do what we have a reason for doing and intentionally attain the end for which we perform this action, as specified by the reason. The analysis is mainly developed to suit physical actions, but it is considered how it needs to be modified to cover mental acts. It is also adapted to fit the notion of letting something be the case by refraining from acting. The analysis of intentional action presented is reductionist in the sense that it does not appeal to any concepts that are distinctive of the domain of action theory, such as a unique type of agent-causation, or irreducible mental acts, like acts of will, volitions, decisions, or tryings. Nor does it appeal to any unanalysed attitudes or states essentially related to intentional action, like intentions and desires to act. Instead, the intentionality of actions is construed as springing from desires conceived as physical states of agents which cause facts because of the way these agents think of them. A sense of our having responsibility that is sufficent for our acting for reasons is also sketched.
