" What I think is true is that at a certain stage in his life, he deliberately ceased to take any interest in himself except as a kind of spiritual alumnus taking his moral finals...Self-knowledge for him had come to mean recognition of his own weakness and shortcomings and nothing more. Anything beyond that he sharply suspected, both in himself and in others, as a symptom of spiritual megalomania. At best, there was so much else, in letters and in life, that he found much more interesting than himself. "
