“But is it not the fact that religion emanates from the nature, from the moral state of the individual? Is it not therefore true that unless the nature be completely exercised, the moral state harmonized, the religion cannot be healthy?”
“A wise architect observed that you could break the laws of architectural art provided you had mastered them first. That would apply to religion as well as to art. Ignorance of the past does not guarantee freedom from its imperfections.”
“Talk to me about the truth of religion and I'll listen gladly. Talk to me about the duty of religion and I'll listen submissively. But don't come talking to me about the consolations of religion or I shall suspect that you don't understand.”
“Not every religion has to have St. Augustine's attitude to sex. Why even in our culture marriages are celebrated in a church, everyone present knows what is going to happen that night, but that doesn't prevent it being a religious ceremony.”
“All religions have based morality on obedience, that is to say, on voluntary slavery. That is why they have always been more pernicious than any political organization. For the latter makes use of violence, the former -- of the corruption of the will.”
“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.”
“All the sweetness of religion is conveyed to the world by the hands of story-tellers and image-makers. Without their fictions the truths of religion would for the multitude be neither intelligible nor even apprehensible; and the prophets would prophesy and the teachers teach in vain.”
“Religion is the dream of the human mind. But even in dreams we do not find ourselves in emptiness or in heaven, but on earth, in the realm of reality; we only see real things in the entrancing splendor of imagination and caprice, instead of in the simple daylight of reality and necessity.”
“Religion I have disposed of all my property to my family. There is one thing more I wish I could give to them, and that is the Christian religion. If they had that and I had not given them one cent, they would be rich. If they have not that, and I had given them the world, they would be poor.”
“A religion, that is, a true religion, must consist of ideas and facts both; not of ideas alone without facts, for then it would be mere Philosophy; -- nor of facts alone without ideas, of which those facts are symbols, or out of which they arise, or upon which they are grounded: for then it would be mere History.”
“My religion consists of a humble admiration of the unlimitable superior who reveals Himself in the slight details we are able to perceive with our frail and feeble minds. That deeply emotional conviction of the presence of a superior reasoning power, which is revealed in the incomprehensible universe, forms my idea of God.”
“You never see animals going through the absurd and often horrible fooleries of magic and religion. Dogs do not ritually urinate in the hope of persuading heaven to do the same and send down rain. Asses do not bray a liturgy to cloudless skies. Nor do cats attempt, by abstinence from cat's meat, to wheedle the feline spirits into benevolence. Only man behaves with such gratuitous folly. It is the price he has to pay for being intelligent but not, as yet, quite intelligent enough.”
“Our knowledge of the historical worth of certain religious doctrines increases our respect for them, but does not invalidate our proposal that they should cease to be put forward as the reasons for the precepts of civilization. On the contrary! Those historical residues have helped us to view religious teachings, as it were, as neurotic relics, and we may now argue that the time has probably come, as it does in an analytic treatment, for replacing the effects of repression by the results of the rational operation of the intellect.”
