The idea that there is a God who rewards and punishes, and who can reward, if he so wishes, the meanest and vilest of the human race, so that he will be eternally happy, and can punish the best of the human race, so that he will be eternally miserable, is subversive of all morality.

The mechanic, when a wheel refuses to turn, never thinks of dropping on his knees and asking the assistance of some divine power. He knows there is a reason.

The highest possible conception of consistency is to be true to the knowledge of today, without the slightest reference to what your opinion was years ago.
