[catalogued under 9. Objects / D. Essence of Objects / 1. Essences of Objects]

Full Idea

The subject-term must always include the predicate-term, in such a way that the man who understood the notion of the subject perfectly would also judge that the predicate belongs to it.

Gist of Idea

Subjects include predicates, so full understanding of subjects reveals all the predicates
