 It is generally agreed that this objection can be answered, and the appearance of conflict with Leibniz’s Law eliminated. We can note that the objection, if sound, would apparently prove too much, since a parallel objection would imply that there can be no such thing as genuine (numerical) identity through change of properties over time. But it is generally accepted that no correct interpretation of Leibniz’s Law should rule this out. For example, Bertrand Russell was thrice married when he received the Nobel Prize for Literature; the one-year-old Bertrand Russell was, of course, unmarried; does Leibniz’s Law force us to deny the identity of the prize-winning adult with the infant, on the grounds that they differ in their properties? No, for it seems that the appearance of conflict with Leibniz’s Law can be dispelled, most obviously by saying that the infant and the adult share the properties of being married in 1950 and being unmarried in 1873, but alternatively by the proposal that the correct interpretation of Leibniz’s Law is that the identity of A and B requires that there be no time such that A and B have different properties at that time (cf. Loux 1979, 42–43; also Chisholm 1967). However, it seems that exactly similar moves are available in the modal case to accommodate ‘change’ of properties across possible worlds. Either we may claim that the actual Bertrand Russell and the playwright in some possible world (say, w2) are alike in possessing the properties of being a philosopher in the actual world and being a non-philosopher in w2, or we may argue that Leibniz’s Law, properly interpreted, asserts that the identity of A and B requires that there be no time, and no possible world, such that A and B have different properties at that time and world. The moral appears to be that transworld identity claims (combined with the view that some of an individual’s properties could have been different) need no more be threatened by Leibniz’s Law than is the view that there can be identity over time combined with change of properties (Loux 1979, 42–43).
