57. "Something red can be destroyed, but red cannot be destroyed, and that is why the meaning of the word 'red' is independent of the existence of a red thing."—Certainly it makes no sense to say that the colour red is torn up or pounded to bits. But don't we say "The red is vanishing"? And don't clutch at the idea of our always being able to bring red before our mind's eye even when there is nothing red any more. That is just as if you chose to say that there would still always be a chemical reaction producing a red flame.—For suppose you cannot remember the colour any more?—When we forget which colour this is the name of, it loses its meaning for us; that is, we are no longer able to play a particular language-game with it. And the situation then is comparable with that in which we have lost a paradigm which was an instrument of our language.
