 If intention is a mental state in relation to which doing A amounts to doing A intentionally, or with the further intention of doing B, that fact would unify the modes of intention with which we began. It would, however, tell us little about intending itself. Does this state involve desire? Belief about what one is doing or what one is going to do? Evaluative judgement? Similar questions arise for those who deny that intention is a mental state and explain it as being on the way to intentional action. Must I want to perform an action I am thus embarked upon? Believe that I am engaged in it? Hold it to be in some way good?
