“ Between optimism and pessimism is the theory of “meliorism,” according to which the world on the whole makes progress in goodness. The average man is pessimist or optimist not on theoretical grounds, but owing to the circumstances of his life, his material prosperity, his bodily health, his general temperament. Perhaps the most characteristic example of unsystematic pessimism is the language of Ecclesiastes, who concludes that “all is vanity.” ”
