“If the account given in Genesis is really true, ought we not, after all, to thank this serpent? He was the first schoolmaster, the first advocate of learning, the first enemy of ignorance, the first to whisper in human ears the sacred word liberty, the creator of ambition, the author of modesty, of inquiry, of doubt, of investigation, of progress and of civilization.”

“Progress is born of doubt and inquiry. The Church never doubts, never inquires. To doubt is heresy, to inquire is to admit that you do not know—the Church does neither.”

“He was a worshiper of liberty, a friend of the oppressed. A thousand times I have heard him quote these words: "For Justice all place a temple, and all season, summer." He believed that happiness is the only good, reason the only torch, justice the only worship, humanity the only religion, and love the only priest.”

“Give me the storm and tempest of thought and action, rather than the dead calm of ignorance and faith! Banish me from Eden when you will; but first let me eat of the fruit of the tree of knowledge!”

“The truth shall make you free, but first it shall make you angry.”

“Liberty a word without which all other words are vain.”

“As man develops, he places a greater value upon his own rights. Liberty becomes a grander and diviner thing. As he values his own rights, he begins to value the rights of others. And when all men give to all others all the rights they claim for themselves, this world will be civilized.”
