Abstract
The following paper is devoted to the discussion of three important and closely interlocked topics in the philosophy of Donald Davidson, the questions: What are reasons? — What are actions? — And: What is the relation between a reason and an action, when the reason explains the action by giving the agent's reason for doing what he did? The last question is actually a quotation; it is the first sentence of Davidson's famous article Actions, Reasons, and Carnes. Although subse-quently modified in various important respects, it still provides the meta-physical groundwork for Davidson's later views on action theory and the philosophy of mind. It is this metaphysical basis that I want to concentrate on. Offhand, Davidson's answers to all the three questions are common in philosophical action theory: Actions are events, reasons are causes of those events, and giving the agent's reason explains an action because it explains the action causally. In what follows, I shall first recapitulate Davidson's reasoning toward the third claim, which I take to be true and to be what Davidson thinks. In discussing a possible objection against this claim I shall then try to show that the second thesis, the thesis that reasons are causes, is neither true nor is it Davidson's opinion. And finally, I want to argue with regard to the first thesis that although Davidson actually holds that actions are events, he should better abandon this position.
