“All religion, my friend, is simply evolved out of fraud, fear, greed, imagination, and poetry.”
― Edgar Allan Poe

“There is not enough love and goodness in the world to permit giving any of it away to imaginary beings.”
― Friedrich Nietzsche, Human, All Too Human: A Book for Free Spirits

“I've begun worshipping the sun for a number of reasons. First of all, unlike some other gods I could mention, I can see the sun. It's there for me every day. And the things it brings me are quite apparent all the time: heat, light, food, and a lovely day. There's no mystery, no one asks for money, I don't have to dress up, and there's no boring pageantry. And interestingly enough, I have found that the prayers I offer to the sun and the prayers I formerly offered to 'God' are all answered at about the same 50% rate.”
― George Carlin, Brain Droppings

“The foundation of irreligious criticism is: Man makes religion, religion does not make man. Religion is, indeed, the self-consciousness and self-esteem of man who has either not yet won through to himself, or has already lost himself again. But man is no abstract being squatting outside the world. Man is the world of man – state, society. This state and this society produce religion, which is an inverted consciousness of the world, because they are an inverted world...

Religious suffering is, at one and the same time, the expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people.

The abolition of religion as the illusory happiness of the people is the demand for their real happiness. To call on them to give up their illusions about their condition is to call on them to give up a condition that requires illusions. The criticism of religion is, therefore, in embryo, the criticism of that vale of tears of which religion is the halo.

Criticism has plucked the imaginary flowers on the chain not in order that man shall continue to bear that chain without fantasy or consolation, but so that he shall throw off the chain and pluck the living flower. The criticism of religion disillusions man, so that he will think, act, and fashion his reality like a man who has discarded his illusions and regained his senses, so that he will move around himself as his own true Sun. Religion is only the illusory Sun which revolves around man as long as he does not revolve around himself.”
― Karl Marx, Critique of Hegel's Philosophy of Right

“The Bible did not arrive by fax from heaven. The Bible is the product of man, my dear. Not of God. The Bible did not fall magically from the clouds. Man created it as a historical record of tumultuous times, and it has evolved through countless translations, additions, and revisions. History has never had a definitive version of the book.”
― Dan Brown, The da Vinci Code

“And the day will come when the mystical generation of Jesus, by the supreme being as his father in the womb of a virgin will be classed with the fable of the generation of Minerva in the brain of Jupiter. But we may hope that the dawn of reason and freedom of thought in these United States will do away all this artificial scaffolding...

“I noticed that all the prayers I used to offer to God, and all the prayers I now offer to Joe Pesci, are being answered at about the same fifty percent rate. Half the time I get what I want, half the time I don't...Same as the four-leaf clover and the horseshoe...same as the voodoo lady who tells you your fortune by squeezing the goat's testicles. It's all the same...so just pick your superstition, sit back, make a wish, and enjoy yourself...”
― George Carlin

“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.”
― Aldous Huxley

“Nothing in Christianity is original.”
― Dan Brown, The da Vinci Code

“At this gathering [Council of Niceau in 324 AD] many aspects of Christianity were debated and voted upon ― the date of Easter, the role of the bishops, the administration of sacraments, and, of course, the divinity of Jesus... until that moment in history, Jesus was viewed by His followers as a mortal prophet... a great and powerful man, but a man nonetheless. A mortal.”
― Dan Brown, The da Vinci Code

“the first quality of an honest man is contempt for religion, which would have us afraid of the most natural thing in the world, which is death; and would have us hate the one beautiful thing destiny has given us, which is life.”
― Umberto Eco, The Island of the Day Before

“The truths of religion are never so well understood as by those who have lost the power of reasoning.”
― Voltaire, Philosophical Dictionary

“So far as the religion of the day is concerned, it is a damned fake ... Religion is all bunk.”
― Thomas A. Edison

“Nonetheless, it still remains true that as a set of cognitive beliefs, religious doctrines constitute a speculative hypothesis of an extremely low order of probability.”
― Sidney Hook, The Quest for Being

“One increasingly hears rumors of a reconciliation between science and religion. In major news magazines as well as at academic conferences, the claim is made that that belief in the success of science in describing the workings of the world is no longer thought to be in conflict with faith in God. I would like to argue against this trend, in favor of a more old-fashioned point of view that is still more characteristic of most scientists, who tend to disbelieve in any religious component to the workings of the universe.”
― Sean Carroll

“Men are moved most by their religion; especially when it is irreligion.”
― G.K. Chesterton, The Everlasting Man

“Religion [dharma] is that where there is no irreligion (adharma, immorality). Religion cannot exist where there is irreligion. There can be only one or the other. Behind every intention, there is either [the force of] religion or [the force of] irreligion.”
― Dada Bhagwan

“Facing death, I saw faith and religion as feeble and childish - almost a kind of entertainment for the healthy and the fortunate - a soul-consuming condition when facing the horrifying reality of death.”
― Sadeq Hedayat, The Blind Owl

“They questioned whether any heaven or hell existed apart from this life: heaven was when men laugh and are merry, hell was sorrow, grief and pain.”
― Christopher Hill, The World Turned Upside Down Radical Ideas During The English Revolution
