ABSTRACT
I FEEL extremely fortunate to have the benefit of comments as acute as those with which Mr. Geach now follows up those previously given me by Professor Sellars (Philosophical Review, LXIV [1955], 405 ff.). I have learned much from both. I should like to return the compliment to Mr. Geach, telling him, in Section I, what I believe is wrong with his analysis of the TMA and, in Section II, what I think both sound and penetrating in his insight into the Platonic Theory. 1
