 Lewis rejects both of these options. He rejects the overlap view because of what he calls ‘the problem of accidental intrinsics’. On the overlap view, having four legs is a relation to a world, and hence not one of Clover’s intrinsic properties. In fact, any aspect of a particular that changes across worlds turns out to be non-intrinsic to that particular. As a consequence, every particular has all its intrinsic properties essentially, which Lewis thinks is unacceptable (1986, 199–209).
