  In any event, there is another well-known reason for doubting that the ‘directness’ of an agent's governance of his own actions involves the condition of causal proximality — that an action is not to be controlled by still another action of the same agent. Some philosophers believe that the agent's moving his leg is triggered and sustained by the agent's trying to move his leg in just that way, and that the efficacious trying is itself an action [see Hornsby 1980, Ginet 1990, and O'Shaughnessy 1973, 1980]. If, in addition, the agent's act of leg moving is distinct from the trying, then, again, the moving of the leg has not been caused proximally by the intention. The truth or falsity of this third assumption is linked with a wider issue about the individuation of action that has also been the subject of elaborate discussion.
