"There is, how­ever, a strong empir­i­cal rea­son why we should cul­ti­vate thoughts that can never be proved. It is that they are known to be use­ful. Man pos­i­tively needs gen­eral ideas & con­vic­tions that will give a mean­ing to his life & enable him to find a place for him­self in the uni­verse. He can stand the most incred­i­ble hard­ships when he is con­vinced that they make sense; he is crushed when on top of all his mis­for­tunes, he has to admit that he is tak­ing part in a ‘tale told by an idiot.’"
