My account is subject to two important limitations. First, I shall be discussing whether or not Aristotle holds to an essentialistic doctrine with regard to sensible particulars, and shall neglect entirely his views about such things as species, genera, universals, and the like. Secondly, I shall be leaving out of account such chronologically late productions as Metaphysics VI-X and IV. Thus I shall be concentrating on the Categories, the Topics, the Physics, and the De Generatione et Corruptione. I am not (...) convinced that later works show substantial change over the works which I shall be discussing, but the later works do present severe exegetical difficulties which could not be adequately met within the scope of this essay.
