 Even if Ackrill can find some plausible route from questions to Aristotle’s categories, the methods he proposes still seem unsatisfactory for the simple reason that they depend far too much on our question-asking inclinations. It may be that the questions that we in fact ask will yield Aristotle’s categories, but what we should want to know is whether we are asking the right questions. Unless we can be confident that our questions are tracking the metaphysical structures of the world, we should be unimpressed by the fact that they yield any set of categories. But to know whether our questions are tracking the metaphysical structures of the world requires us to have some way of establishing the correctness of the categorial scheme. Clearly, at this point, we are in a circle that is too small to be of much help. Maybe all metaphysical theorizing is at some level laden with circularity, but circles this small are generally unacceptable to a metaphysician.
