The need of exercise is a modern superstition, invented by people who ate too much and had nothing to think about.

Sex endows the individual with a dumb and powerful instinct, which carries his body and soul continually towards another, makes it one of the dearest employments of his life to select and pursue a companion, and joins to possession the keenest pleasure, to rivalry the fiercest rage, and to solicitude an eternal melancholy. What more could be needed to suffuse the world with the deepest meaning and beauty?

The aim of life is some way of living, as flexible and gentle as human nature; so that ambition may stoop to kindness, and philosophy to condor and humor. Neither prosperity nor empire nor heaven can be worth winning at the price of a virulent temper, bloody hands, an anguished spirit, and a vain hatred of the rest of the world.

When a man's life is over, it remains true that he was one sort of man and not another. A man who understands himself under the form of eternity knows the quality that eternally belongs to him, and knows that he cannot wholly die, even if he would, for when the movement of his life is over, the truth of his life remains.

My atheism, like that of Spinoza, is true piety towards the universe and denies only gods fashioned by men in their own image, to be servants of their human interests.
