Modus Ponens - Formal Proof

Famous quotes containing the words formal and/or proof:

“It is in the nature of allegory, as opposed to symbolism, to beg the question of absolute reality. The allegorist avails himself of a formal correspondence between “ideas” and “things,” both of which he assumes as given; he need not inquire whether either sphere is “real” or whether, in the final analysis, reality consists in their interaction.”
—Charles, Jr. Feidelson, U.S. educator, critic. Symbolism and American Literature, ch. 1, University of Chicago Press (1953)

“The moment a man begins to talk about technique that’s proof that he is fresh out of ideas.”
—Raymond Chandler (1888–1959)
