[catalogued under 9. Objects / F. Identity among Objects / 1. Concept of Identity]

Full Idea

Every man of common sense has a clear and distinct notion of identity. If you ask for a definition of identity, I confess I can give none. It is too simple a notion.

Gist of Idea

Identity is familiar to common sense, but very hard to define

A Reaction

'Identical' seems to be a two-place predicate, but the only strict way two things can be identical is if there is actually just one thing. In which case just drop the word 'identity' (instead of defining it), and say there is just one thing here.
