From Living with the Devil by Stephen Batchelor, author of Buddhism Without Beliefs:
"I yearn to be free of pain," wrote the eighth-century Indian Buddhist Shantideva, "but rush straight into it; I long for happiness, but foolishly crush it like an enemy." A thousand years later, Pascal noted how "we desire truth and find in ourselves nothing but uncertainty. We seek happiness and find only misery and death." Such contradictoriness is more than an occasional moral lapse that could be corrected by the fear of punishment or a timely boost of righteousness. It appears to be knit into the fabric of existence itself.
