It is only great pain--that slow, sustained pain that takes its time, in which we are, as it were, burned with smoldering green firewood--that forces us philosophers to sink to our ultimate profundity and to do away with all the trust, everything good-natured, veil-imposing, mild and middling, on which we may have previously based our humanity. I doubt that such a pain makes us 'better'--but I know that it makes us deeper.
