One of the roles of matter in Aristotle's philosophy, according to well-established historical tradition, is to provide a principle of individuation. This tradition has been challenged from time to time. Some historians, noting that it is form rather than matter that wears the metaphysical trousers for Aristotle, have tried to give form the role of providing a principle of individuation. Others have suggested that there is no such principle at all to be found in Aristotle's works. This ongoing dispute has (...) been frequently flawed by a failure to be sufficiently clear precisely what problem a principle of individuation is supposed to provide an answer to. (shrink)
