" Of an apartment-building manager who had killed himself I was told he had lost his daughter five years before, that he had changed greatly since, and that the experience had "undermined" him. A more exact word cannot be imagined. Beginning to think is beginning to be undermined. Society has but little connection with such beginnings. The worm is in man's heart - that is where it must be sought. "
