 We have seen that the decisions of a practically wise person are not mere intuitions, but can be justified by a chain of reasoning. (This is why Aristotle often talks in term of a practical syllogism, with a major premise that identifies some good to be achieved, and a minor premise that locates the good in some present-to-hand situation.) At the same time, he is acutely aware of the fact that reasoning can always be traced back to a starting point that is not itself justified by further reasoning. Neither good theoretical reasoning nor good practical reasoning moves in a circle; true thinking always presupposes and progresses in linear fashion from proper starting points. And that leads him to ask for an account of how the proper starting points of reasoning are to be determined. Practical reasoning always presupposes that one has some end, some goal one is trying to achieve; and the task of reasoning is to determine how that goal is to be accomplished. (This need not be means-end reasoning in the conventional sense; if, for example, our goal is the just resolution of a conflict, we must determine what constitutes justice in these particular circumstances. Here we are engaged in ethical inquiry, and are not asking a purely instrumental question.) But if practical reasoning is correct only if it begins from a correct premise, what is it that insures the correctness of its starting point?
