It is impossible for me to conceive of a character more utterly detestable than that of the Hebrew god.

Liberty is the condition of progress. Without Liberty, there remains only barbarism. Without Liberty, there can be no civilization.

Talent has the four seasons: spring, that is to say, the sowing of the seeds; summer, growth; autumn, the harvest; winter, intellectual death. But there is now and then a genius who has no winter, and, no matter how many years he may live, on the blossom of his thought no snow falls. Genius has the climate of perpetual growth.

There is something tenderly appropriate in the serene death of the old. Nothing is more touching than the death of the young, the strong.

I am simply in favor of intellectual hospitality-that is all. You come to me with a new idea. I invite you into the house. Let us see what you have. Let us talk it over. If I do not like your thought, I will bid it a polite "good day." If I do like it, I will say: "Sit down; stay with me, and become a part of the intellectual wealth of my world."

They say: Belief is important. I say: No, actions are important. Judge by deed, not by creed.

Fear paints pictures of ghosts and hangs them in the gallery of ignorance.
