In the past thirty years or so, the doctrine that actions are events has become an essential, and sometimes unargued, part of the received view in the philosophy of action, despite the efforts of a few philosophers to undermine the consensus. For example, the entry for Agency in a recently published reference guide to the philosophy of mind begins with the following sentence:
A central task in the philosophy of action is that of spelling out the differences between events in general and those events that fall squarely into the category of human action.
There is no consensus about what events are. But it is generally agreed that, whatever events may prove to be, actions are a species or a class of events.
We believe that the received view is mistaken: actions are not events. We concede that for most purposes, the kind of categorial refinement which is involved in either affirming or denying that actions are events is frankly otiose. Our common idiom does not stress the difference between actions and events, at least not in general terms, because it has no need to. Perhaps it sounds a little odd to say that some events are performed; but if we balked at describing, say, the abdication of Edward VIII as one of the politically significant events in Britain in 1936, it could not be for metaphysical reasons. And since actions, like events, are datable — though often, as we shall see, only imprecisely — actions are said to take place and to occur. But an important class of actions consist in moving something; indeed, according to many philosophers, every action consists in moving something. And when we consider actions of this sort from a theoretical point of view it becomes imperative to distinguish between actions and events. Or so we shall argue.
