Single Idea 1675

[catalogued under 8. Modes of Existence / D. Universals / 2. Need for Universals]

Full Idea

There need be no forms (one item apart from the many) for demonstrations. But there must be universals, where one thing holds of the many. Without universals there are no middle terms, and so no demonstrations.

Gist of Idea

Separate Forms aren't needed for logic, but universals (one holding of many) are essential
