Gist of Idea

Being 'the same' is meaningless, unless we specify 'the same X'

A Reaction

Geach seems oddly unaware of the perfect identity of Hespherus with Phosphorus. His critics don't spot that he was concerned with identity over time (of 'the same man', who ages). Perry's critique emphasises the type/token distinction.
