Full Idea
A problem for Gallois is that he leaves us no way to talk about questions of genuine identity through time, and thus undercuts one motivation for his own position.
Gist of Idea
Gallois hoped to clarify identity through time, but seems to make talk of it impossible

A Reaction
Gallois seems to need a second theory of identity to support his Occasional Identity theory. Two things need an identity each, before we can say that the two identities coincide. (Time to read Gallois!)
