For the first time I understood the dogma of eternal pain... For the first time my imagination grasped the height and depth of the Christian horror. Then I said: "It is a lie, and I hate your religion. If it is true, I hate your God." From that day I have had no fear, no doubt. For me, on that day, the flames of hell were quenched. From that day I have passionately hated every orthodox creed. That Sermon did some good.

Nothing could be more dangerous to the existence of this Republic than to introduce religion into politics

Man must learn to rely upon himself. Reading bibles will not protect him from the blasts of winter, but houses, fires. and clothing will. To prevent famine, one plow is worth a million sermons, and even patent medicines will cure more diseases than all the prayers uttered since the beginning of the world.

Character survives; goodness lives; love is immortal.

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.

Happiness is not a reward - it is a consequence. Suffering is not a punishment - it is a result.

Intellectual liberty is the air of the soul, the sunshine of the mind, and without it, the world is a prison, the universe is a dungeon.
