Single Idea 15749

[catalogued under 8. Modes of Existence / B. Properties / 13. Tropes / b. Critique of tropes]

Full Idea

Trope theory has the drawback that we need the primitive notion of duplicate tropes, whereas with universals we just say that it is one and the same universal through some charged particles.

Gist of Idea

Trope theory (unlike universals) needs a primitive notion of being duplicates

A Reaction

The normal term for this primitive is 'perfect resemblance', though that seems to make close resemblance a bit complicated and puzzling. I'm not sure if I understand resemblance as a feature of the world, rather than of our minds.
