Give any orthodox church the power, and to-day they would punish heresy with whip, and chain, and fire. As long as a church deems a certain belief essential to salvation, just so long it will kill and burn if it has the power.

My heart was filled with gratitude, with thankfulness, and went out in love to all the heroes, the thinkers who gave their lives for the liberty of hand and brain... to all the wise, the good, the brave of every land, whose thoughts and deeds have given freedom to the sons of men. And then I vowed to grasp the torch that they had held, and hold it high, that light might conquer darkness still.

Love is the magician, the enchanter, that changes worthless things to joy, and makes right royal kings and queens of common clay. It is the perfume of that wondrous flower, the heart, and without that sacred passion, that divine swoon, we are less than beasts; but with it, earth is heaven, and we are gods.

We do not need the forgiveness of God, but of each other and of ourselves.

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.

The man who accepts opinions because they have been entertained by distinguished people, is a mental snob.

Theology is not what we know about God, but what we do not know about Nature.
