Single Idea 3145

[from 'Contemporary Philosophy of Mind' by Georges Rey, in 9. Objects / F. Identity among Objects / 7. Indiscernible Objects ]

Full Idea

Leibniz's Law, the indiscernibility of identicals, is a truism which should not be confused with the more controversial identity of indiscernibles, which depends on the possibility of perfectly replicated universes.

Gist of Idea

The Indiscernibility of Identicals is a truism; but the Identity of Indiscernibles depends on possible identical worlds
