  Throughout the Categories Aristotle assumes that relations comprise one of the accidental categories, and hence that they must be understood as items inhering in particular substances. This helps to explain why, unlike contemporary philosophers, who speak of relations as holding between two or more things, Aristotle prefers to speak of them as inhering in one thing and somehow pointing toward (pros) another. Indeed, Aristotle’s preferred name for relations is just ‘things toward something’ (ta pros ti).
