Relativity, categories and principles in the diuisio aristotelea 67M/32DL

The Diuisio Aristotelea 67M/32DL draws a distinction between two categories of beings, per se and relatives. I defend three main theses. First, that the relation of dependence characterizing the members of the latter category is modal and symmetrical in nature and, accordingly, the per se-relatives contrast cannot be equivalent to the substance-accidents contrast. Second, that the type of relativity relevant to this diuisio is both ontological and semantic in nature (but with different emphases depending on the version of the diuisio considered). Third, I argue, against a widespread opinion, that the last line of the DL version of the diuisio does not concern metaphysical principles. Here I also compare the diuisio to other Early Academic bicategorial schemes and show that they differ from one another significantly, especially as far as the alleged connection between categories and metaphysical principles is concerned.
