 Much of Davidson’s early work was in decision theory (see Decision-Making: An Experimental Approach [1957]), and it was not until the early 1960s that the work for which he is best known began to appear in print. Indeed, Davidson’s first major philosophical publication was the seminal paper ‘Actions, Reasons and Causes’ (1963). In that paper Davidson sets out to defend the view that the explanation of action by reference to reasons (something we do, for instance, when we refer to an agent’s intentions or motives in acting) is also a form of causal explanation. Indeed, he argues that reasons explain actions just inasmuch as they are the causes of those actions. This approach was in clear opposition to the Wittgensteinian orthodoxy of the time. On this latter account causal explanation was viewed as essentially a matter of showing the event to be explained as an instance of some law-like regularity (as we might explain the whistling of a kettle by reference to certain laws involving, among other things, the behaviour of gases under pressure). Since rational explanation was held, in general, not to involve any such reference to laws, but rather required showing how the action fitted into some larger pattern of rational behaviour, explanation by reference to reasons was held to be distinct from and independent of explanation by reference to causes.
