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.

I have not the slightest confidence in 'spiritual manifestations.'

Our ignorance is God; what we know is science. When we abandon the doctrine that some infinite being created matter and force, and enacted a code of laws for their government ... the real priest will then be, not the mouth-piece of some pretended deity, but the interpreter of nature.

I love to think of the whole universe together as one eternal fact. I love to think that everything is alive; that crystallization is itself a step toward joy. I love to think that when a bud bursts into blossom: it feels a thrill. I love to have the universe full of feeling and full of joy, and not full of simple dead, inert matter, managed by an old bachelor for all eternity.

Life is a narrow vale between the cold and barren peaks of two eternities. We strive in vain to look beyond the heights. We cry aloud-and the only answer is the echo of our wailing cry. From the voiceless lips of the unreplying dead there comes no word. But in the night of Death Hope sees a star and listening Love can hear the rustling of a wing.

Do not trust those in whom the compulsion to punish is strong.

It cannot be said too often that actions are good or bad in the light of consequences, and that a clear perception of consequences would control actions. That which increases the sum of human happiness is moral; and that which diminishes the sum of human happiness is immoral. . . . Blind, unreasoning obedience is the enemy of morality.
