Single Idea 12672

[catalogued under 8. Modes of Existence / B. Properties / 11. Properties as Sets]

Full Idea

To regard properties as sets of individuals, and relations as sets of ordered individuals, is to make a nonsense of the whole idea of discovering a new property or relationship. Sets are defined or constructed, not discovered.

Gist of Idea

Properties and relations are discovered, so they can't be mere sets of individuals

A Reaction

This bizarre view of properties (as sets) drives me crazy, until it dawns on you that they are just using the word 'property' in a different way, probably coextensively with 'predicate', in order to make the logic work.
