Abstract
In this century, much of the discussion of the free will problem has centered around the conditional analysis of ‘can’. Following G.E. Moore, most compatibilists have based their position on the supposition that to say a person could have acted otherwise is simply to say that he would have acted otherwise, if he had chosen to. Most incompatibilists have rejected this supposition, arguing that it must not only be true that a person would have acted otherwise if he had chosen to, but that it must also be true that the person could have chosen otherwise than he did. I think that incompatibilists are right here. The question whether determinism entails lack of free will comes down to the question whether determinism entails that no one could have chosen otherwise than he did.
