It is only possible to succeed at second-rate pursuits—like becoming a millionaire or a prime minister, winning a war, seducing beautiful women, flying thought the stratosphere or landing on the moon. First-rate pursuits—involving, as they must, trying to understand what life is about and trying to convey that understanding—inevitably result in a sense of failure. A Napoleon, a Churchill, a Roosevelt can feel themselves to be successful, but never a Socrates, a Pascal, a Blake. Understanding is for ever unattainable. Therein lies the inevitablility of failure in embarking upon its quest, which is none the less the only one worthy of serious attention.
