Single Idea 14477

[filed under theme 9. Objects / F. Identity among Objects / 6. Identity between Objects ]

Full Idea

Identity claims are only true if the entities referred to are of the same category, and meet the criteria of identity appropriate for things of that category.

Gist of Idea

Identical entities must be of the same category, and meet the criteria for the category

A Reaction

This may be a little too optimistic about having a set of clear-cut and reasonably objective categories to work with, but attempts at establishing metaphysical categories have not gone especially well.
