Classifying Predicates Into Ten Types

If you think about all the features that can be predicated of some you see that they will fall into these ten types. This whole project of classifying predicates into ten classes is not something aristotle necessarily thought up on his own. Scholars believe that it originated in the context of plato's academy, where aristotle studied for many years. They wanted to make sure that they had a category for every predicate they could think of.
