[Wither] knew that everything was lost. It is incredible how little this knowledge moved him. What had been in his far-off youth a merely aesthetic repugnance to realities that were crude or vulgar, had deepened and darkened, year after year, into a fixed refusal of everything that was in any degree other than himself. He had passed from Hegel into Hume, thence through Pragmatism, and thence through logical Positivism, and out at last into the complete void. The indicative mood now corresponded to no thought that his mind could entertain. He had willed with his whole heart that there should be no reality and no truth, and now even the imminence of his own ruin could not wake him.
