Abstract

IT is tempting to assume that an obvious way in which Aristotle determined his list of categories was to take a primary substance as subject and classify its predicates. The advantage of this suggestion is that it appears to give us the list of categories given at Categories 1b25 ff. For example, if we take Socrates as subject, then, when we predicate man of him, we get a predicate which is a substance. When we consider "Socrates is grammatical" we get a predicate in quality or "how qualified". "Socrates is in the market place" gives us place or "where" and so on.
