Single Idea 11886

[filed under theme 9. Objects / D. Essence of Objects / 3. Individual Essences ]

Full Idea

If all objects had individual essences, there would be no numerical difference without an essential difference. But if there aren't individual essences, there could be two things sharing all essential properties, differing only in accidental properties.

Gist of Idea

There are problems both with individual essences and without them

A Reaction

Depends how you define individual essence. Why can't two electrons have the same individual essence. To postulate a 'kind essence' which bestows the properties on each electron is to get things the wrong way round.
