André Gallois' recent book Occasions of Identity attempts to defend the coherence of the view that objects may be identical at one time but distinct at another (the occasional identity thesis). The defence requires a special account of rigid designation and a special version of Leibniz' law. This paper shows Gallois' proposals in this regard to be inadequate, and suggests a better line of defence for occasional identity theorists.
