So much depends upon imagination. This was really Williams's point. We must insist on imagining things—even, and perhaps especially, those things that are real, all too real. Or, to use Wittgenstein's phrase, we must insist on making, for ourselves, pictures of the facts. They do not make themselves known. Only in imagination can they be situated in a field of action; only here can they find a human measure, a sense of the possible, a glimpse of the ideal.
