And here we say, “But surely designing a new shape isn't in itself changing one's taste, – – and saying a word isn't meaning it, – – and saying that I believe isn't believing; there must be feelings, mental acts, going along with these lines and these words.” ‒ ‒ And the reason we give for saying this is
104.
that a man certainly could design a new shape without having changed his taste, say that he believes something without believing it, etc. And this obviously is true. But it doesn't follow that what distinguishes a case of having changed one's taste from a case of not having done so isn't under certain circumstances just designing what one hasn't designed before. Nor does it follow that in cases in which designing a new shape is not the criterion for a change of taste, the criterion must be a change in some particular region of our mind.
