"The conduct of God who disposes all things kindly, is to put religion into the mind by reason, and into the heart by grace. But to attempt to put it into the mind and heart by force and threats is not to put religion there, but terror."
"All great religions, in order to escape absurdity, have to admit a dilution of agnosticism. It is only the savage, whether of the African bush or the American gospel tent, who pretends to know the will and intent of God exactly and completely."
"The churches ... have lost much of their authority over youth because they have refused to re-examine their religious sanctions and their dogmatic preaching in the light of modern physiology, psychology and sociology."
"Our rural village life was a purifying, uplifting influence that fortified us against the later impacts of urbanization; Church and State, because they were separated and friendly, had spiritual and ethical standards that were mutually enriching; freedom and discipline, individualism and collectivity, nature and nurture in their interaction promised an ever stronger democracy. I have no illusions that those simpler, happier days can be resurrected."
"Nobody can deny but religion is a comfort to the distressed, a cordial to the sick, and sometimes a restraint on the wicked; therefore whoever would argue or laugh it out of the world without giving some equivalent for it ought to be treated as a common enemy."
"What we are told of the inhabitants of Brazil, that they never die but of old age, is attributed to the tranquility and serenity of their climate; I rather attribute it to the tranquility and serenity of their souls, which are free from all passion, thought, or any absorbing and unpleasant labors. Those people spend their lives in an admirable simplicity and ignorance, without letters, without law, without king, without any manner of religion."
"Sometime after the Enlightenment, science and religion came to a gentleman's agreement. Science was for the real world: machines, manufactured things, medicines, guns, moon rockets. Religion was for everything else, the immeasurable: morals, sacraments, poetry, insanity, death, and some residual forms of politics and statesmanship. Religion became, in both senses of the word, immaterial. Science and religion were apples and or anges. So the pact said: render unto apples the things that are Caesar's, and unto oranges the things that are God's. Just as the Maya kept two calendars, one profane and one priestly, so Western science and religion fell into two different conceptions of the universe, two different vocabularies."
"Where is there such an one who has not a thousand times been struck with a sort of infidel idea, that whatever other worlds God may be Lord of, he is not the Lord of this; for else this world would seem to give the lie to Him; so utterly repugnant seem its ways to the instinctively known ways of Heaven."
