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.’
