  Predicability, then, is not a sufficient condition of categoricity, but non-predicability is a sufficient disqualification. For Aristotle, the individual is not, strictly speaking, predicable, although there are places in which he speaks of the individual as predicable. Examples of individuals are this horse and a certain point of grammar present in the knower (1b5). The first is what Aristotle calls a primary substance, which he defines in Categories as that which is neither predicable of, nor present in, a subject (2a11). The second is, like a primary substance, non-predicable, but it can be present in a subject. Both are individual and neither is predicable.
