Single Idea 11205

[filed under theme 8. Modes of Existence / D. Universals / 6. Platonic Forms / d. Forms critiques ]

Full Idea

If (in the Platonic view) manyness was contained in humanness it could never be one as it is in Socrates, and if oneness was part of its definition then Socrates would be Plato and the nature couldn't be realised more than once.

Gist of Idea

If the form of 'human' contains 'many', Socrates isn't human; if it contains 'one', Socrates is Plato

Source

Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.100)

A Reaction

I suppose the reply is that since we are trying to explain one-over-many, then this unusual combination of both manyness and oneness is precisely what distinguishes forms from other ideas.
