 For our purposes, we need not determine how to best interpret Aristotle’s theory of relatives, but can rather consider some issues that Aristotle’s discussion raises. First, anyone who is comfortable with relational properties will no doubt find Aristotle’s discussion somewhat confused. Although Aristotle does discuss important features of relational predicates, for instance, that relational predicates involve a kind of reciprocal reference (6b28), his fundamental stance, according to which all properties in the world are non-relational, will appear wrongheaded. Second, Aristotle’s category of relatives raises interpretive issues, in particular the issue concerning what exactly his categorical scheme is meant to classify. As in the case of quantity, Aristotle seems to be focusing on things that are related rather than relations themselves. Indeed, this is evident from the name of the category.
