"Already all of us must have heard about the people who call themselves the Fundamentalists. Their apparent intention is to drive out of the evangelical churches men and women of liberal opinions. I speak of them the more freely because there are no two denominations more affected by them than the Baptist and the Presbyterian. We should not identify the Fundamentalists with the conservatives. All Fundamentalists are conservatives, but not all conservatives are Fundamentalists. The best conservatives can often give lessons to the liberals in true liberality of spirit, but the Fundamentalist program is essentially illiberal and intolerant."

“The men of faith might claim for their positions ancient tradition, practical usefulness, and spiritual desirability, but one query could prick all such bubbles: Is it scientific? That question has searched religion for contraband goods, stripped it of old superstitions, forced it to change its categories of thought and methods of work, and in general has so cowed and scared religion that many modern-minded believers... instinctively throw up their hands at the mere whisper of it... When a prominent scientist comes out strongly for religion, all the churches thank Heaven and take courage, as though it were the highest possible compliment to God to have Eddington believe in Him. Science has become the arbiter of this generation's thought, until to call even a prophet and a seer "scientific" is to cap the climax of praise.”

“Hold a picture of yourself long and steadily enough in your mind's eye and you will be drawn toward it. Picture yourself vividly as defeated and that alone will make victory impossible. Picture yourself vividly as winning, and that alone will contribute immeasurably to success. Do not picture yourself as anything and you will drift like a derelict.”

“Life consists not simply in what heredity and environment do to us but in what we make out of what they do to us.”

“I renounce war for its consequences, for the lies it lives on and propagates, for the undying hatred it arouses, for the dictatorships it puts in place of democracy, for the starvation that stalks after it. I renounce war, and never again, directly or indirectly, will I sanction or support another.”

“Don't simply retire from something; have something to retire to.”

“Rebellion against your handicaps gets you nowhere. Self-pity gets you nowhere. One must have the adventurous daring to accept oneself as a bundle of possibilities and undertake the most interesting game in the world — making the most of one's best.”
