No working hypothesis means no motive for research, no reason for making one experiment rather than another, no way of bringing sense or order into the observed facts. Contrariwise, too much working hypothesis means finding only what you already know to be there and ignoring the rest. Dogma turns a man into an intellectual Procrustes. He goes about forcing things to become the signs of his word-patterns, when he ought to be adapting his word-patterns to become the signs of things.
