18440 | Identity of physical objects is just being coextensive [Quine] |
Full Idea: Physical objects are identical if and only if coextensive. | |

A reaction: The supposed counterexample to this is the statue and the clay it is made of, which are said to have different modal properties (destroying the statue doesn't destroy the clay). |
