 The way in which I have characterized the concepts of said-of and present-in is, as I have said, natural and relatively straightforward. Moreover, it was by far the orthodox interpretation amongst Aristotle’s Medieval interpreters. I would be remiss, however, were I not to mention the recent debate started by G.E.L. Owen about the said-of/present-in distinction (Owen, 1965a). According to Owen, Aristotle did not accept the existence of non-substantial particulars. Instead, Owen argues, a being that is not said-of but present-in primary substances is an accidental universal of the lowest possible generality. Hence, Owen denies that the said-of/not-said-of distinction is one between universals and particulars. I shall not discuss Owen’s interpretation but shall simply note that it has spawned a huge deal of scholarly attention. The interested reader can find a discussion of these issues here:
