Full Idea

The most prominent objection to contingent identity (as in the case of the statue and its clay) is that it violates Leibniz's Law.

A Reaction

Depends what you mean by a property. The trickiest one would be that the statue has (right now) a disposition to be worth a lot, but the clay doesn't. But I don't think that is really a property of the statue. Properties are a muddle.
