“The more narrowly we examine language, the sharper becomes the conflict between it and our requirement. (For the crystalline purity of logic was, of course, not a result of investigation; it was a requirement.) The conflict becomes intolerable; the requirement is now in danger of becoming empty. – We have got onto slippery ice where there is no friction and so in a certain sense the conditions are ideal, but also, just because of that, we are unable to walk. We want to walk; so we need friction. Back to the rough ground!”
-Ludwig Wittgenstein-
Great quote. And I love the play on the word “fiction.”
