“It leads to a realization that man is not a constant, unchanging being: he is one person one day, another person the next. He forgets easily, lives in the moment, seldom exerts will-power, and even when he does, gives up and turns to something else. No wonder that poets feel such despair when they seem to catch a glimpse of some intenser state of consciousness, and know with absolute certainty that nothing they can do can hold it fast.”
