“ What is the precise effect of our argument on the subject of the human mind? Its precise effect and bearing is to turn us to the study of fact—of a clear and a peculiar fact—from the contemplation of an object which is either an hypothesis, or else no object at all (not even an hypothesis but a contradiction) , or else an irrelevant object of research, and one which cannot by any conceivability contain the fact which it is our business to investigate. ”
