70. "But if the concept 'game' is uncircumscribed like that, you don't really
know what you mean by a 'game'."—When I give the description: "The ground was
quite covered with plants"—do you want to say I don't know what I am talking
about until I can give a definition of a plant?
My meaning would be explained by, say, a drawing and the words "The ground looked roughly like this". Perhaps I even say "it looked exactly like this."—Then were just this grass and these leaves there, arranged just like this? No, that is not what it means. And I should not accept any picture as exact in this sense.
