Individuo e Individuale in Aristotele

This is a translation into Italian, accompanied by a brief commentary of chapter 2 of Aristotle’s Categories. In this text Aristotle presents the distinction between individual substances such as Socrates or Bucephalus and their species and genera as the distinction between primary (prw=tai) and secondary (deu/terai) substances (2a11-19). This distinction, in turn, is a distinction between substances that are particulars and substances that are universals. In the Categories Aristotle defines a primary substance as that which is neither said of nor in a subject (2a11–13). Being said of a subject and being in a subject are the only relations of metaphysical predication Aristotle recognizes in the Categories.
