 The third challenge is the most troublesome of all. In section 2 it was noted that Leibniz’s Law (and its contrapositive) appear to be crucial to our understanding of identity and distinctness. But it seems that the defender of strong Composition as Identity must deny this. After all, the bricks are many, but the wall is one. The onus is thus on the defender of strong Composition as Identity to explain why we should think the “are” in hybrid identity statements really expresses the relation of identity.
