Causal theories of action are attempts to develop an account of actions in terms of events which have the right kind of causal ancestry. The causal ancestry must be traced back to some kind of intentional state in the agent, such intentional state must have the right kind of content, and it must cause the bodily movement in the ‘right’ way. Causal accounts differ on the nature of the intentional state, the nature of the content it must have, and the (...) specification of the ‘right’ kind of causal connection to bodily movements or other effects. Causal accounts also differ on the identification of the action itself. Some acounts say that the action is the bodily movement, provided that it was caused in the right way and had the right kind of effects. Others identify the action with the triggering intentional state, provided that it has the right kind of effects. Yet others identify the action with the composite event of the intentional state's causing the appropriate effects. Finally there are those which fail to identify the action with any of these events or combinations of them. (shrink)

In 'A Theory of Human Action' (1970) Alvin Goldman launched an attack on what has become known as the Anscombe-Davidson Identity Thesis. In brief, this is the thesis that our acts are our body movements, and that all the different effects of that movement do not entail that different acts have been performed, but only that an identical act has different descriptions. In her response to Goldman, Anscombe (1981) claims that Goldman is arguing at cross-purposes. I will argue that this (...) is partially true, but only because she accepts what I shall call the Symmetry Thesis. This thesis in turn is natural if you accept a third thesis called the Irreducibility Thesis. These three theses form a consistent set that the defenders of the Identity Thesis would accept and its detractors would deny. It follows that the best way to attack the Identity Thesis is to attack the Irreducibility Thesis on which it is based. I believe that this can be done and that Goldman is basically right, but I will not be concerned with a full defense of Goldman's method of individuating actions against its competitors. Rather, I want to show the grounds, some of them extralogical, upon which preference can be made. (shrink)
