 The second possibility, which is what the examples Collins gives really suggest, is that all numerical powers are emergent and do not conform to the Composition Principle. All generical powers, on the other hand, do conform to the Homogeneity Principle. If the second interpretation is true, Collins thinks that all of Clarke’s first category powers, or at least his favorite ones, can be treated as wholes that have properties not had by the parts. This would indeed be a change of position, but in just the opposite direction to the one that Rozemond supposes. But, even on this second interpretation, all generical properties conform to the Homogeneity Principle. So, why isn’t Collins in trouble in the way Rozemond claims? The answer is that the use of the Homogeneity Principle in Locke’s proof for the existence of God is not the only reference to that principle in Locke’s Essay.
