In 2006 a member posted a thread on our message board to ask other atheists about favorite quotes that are anti-religious.  The first post of this thread has been edited, to compile most of these atheist quotes in one place.  Some of these quotes can be found at Celebatheists.com.  In creating a new thread the original URL to this page created an error, this recreated page resolves that error.  This thread doesn't accept comments.  Please post comments in the other thread for these great atheist quotes.

"Without religion, we'd have good people doing good things, and evil people doing evil things. But for good people to do evil things, that takes religion." Stephen Weinburg

 ""Shake off all the fears of servile prejudices, under which weak minds are servilely crouched. Fix reason firmly in her seat, and call on her tribunal for every fact, every opinion. Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason than that of blindfolded fear. " Thomas Jefferson

"Believing with you that religion is a matter which lies solely between man and his God, that he owes account to none other for his faith or his worship, that the legislative powers of government reach actions only, and not opinions, I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should 'make no law respecting an establishment of religion, or prohibiting the free exercise thereof,' thus building a wall of separation between church and State." Thomas Jefferson

"To talk of immaterial existences is to talk of nothings. To say that the human soul, angels, god, are immaterial, is to say they are nothings, or that there is no god, no angels, no soul. I cannot reason otherwise: but I believe I am supported in my creed of materialism by Locke, Tracy, and Stewart. At what age of the Christian church this heresy of immaterialism, this masked atheism, crept in, I do not know. But heresy it certainly is." Thomas Jefferson

"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 Minerve in the brain of Jupiter." Thomas Jefferson

"Tell me there is a God in the serene heavens that will damn his children for the expression of an honest belief! More men have died in their sins, judged by your orthodox creeds, than there are leaves in all the forests in the wide world ten thousand times over. Tell me these men are in Hell; that these men are in torment; that these children are in eternal pain, and that they are to be punished forever and forever! I denounce this doctrine as the most infamous of lies." - Robert G. Ingersoll

"The Christian god can easily be pictured as virtually the same god as the many ancient gods of past civilizations. The Christian god is a three headed monster; cruel, vengeful and capricious. If one wishes to know more of this raging, three headed beast-like god, one only needs to look at the caliber of people who say they serve him. They are always of two classes: fools and hypocrites." - Thomas Jefferson

"Faith: not wanting to know what is true." - Friedrich Nietzsche (1844-1900)

"The being we call god is merely a pawn working for a powerful and rational force in some far-off galaxy. This force is trying to weed out people who are irrational by seeing who would be stupid enough to believe in his god illusion so easily. Those that believe in this illusion, he will send to eternal damnation and he will deliver the rational beings, those who stoically refused to believe in a god, to heaven." - Nicholas Yee

If the gods listened to the prayers of men, all humankind would quickly perish since they constantly pray for many evils to befall one another. - Epicurus

Is God willing to prevent evil, but not able?

Then he is malevolent.
Is he both able and willing?
Then whence cometh evil?
Is he neither able nor willing?
Then why call him God? - Epicurus

God Himself, sir, does not propose to judge a man until his life is over. Why should you and I? - Samuel Johnson

I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use. - Galileo

To judge from the notions expounded by theologians, one must conclude that God created most men simply with a view to crowding hell. - Marquis De Sade

God is a comedian playing to an audience too afraid to laugh. - Voltaire

God is the great mysterious motivator of what we call nature and it has been said often by philosophers, that nature is the will of God
. And, I prefer to say that nature is the only body of God that we shall ever see.
- Frank Lloyd Wright

Forgive, O Lord, my little jokes on Thee
And I'll forgive Thy great big one on me.
- Robert Frost

To know a person's religion we need not listen to his profession of faith but must find his brand of intolerance. - Eric Hoffer

If I were personally to define religion, I would say that it is a bandage that man has invented to protect a soul made bloody by circustance. - Theodore Dreiser

A country dominated by televangelism would be unrecognizable to the Founding Fathers, who envisioned religion as personal and spiritua, not social and political. No particular variety of religion was intended to control the political agenda, to set the community's moral tone or to judge who are the true believers and members of our society. But this is precisely the objective of the electric church - Razelle Frankel

My faith is that the only soul a man must save is his own. - William Orville Douglas

"I refuse to prove that I exist" says God, "for proof denies faith, and without faith, I am nothing."  "Oh," says man, "but the Babel Fish is a dead give-away, isn't it?  It proves You exist, and so therefore You don't.  Q.E.D."  "Oh, I hadn't thought of that," says God, who promptly vanishes in a puff of logic.  ~ Douglas Adams, Hitchhiker's Guide to the Galaxy

Moral:  a peerless maxim enumerated by God in his Holy Bible, such as that of Deut. 23:1, if your testicles are crushed or your male member missing, you must never enter a sanctuary of the Lord.  ~ Donald Morgan

There is a story, which is fairly well known, about when the missionaries came to Africa.  They had the Bible and we, the natives, had the land.  They said "Let us pray," and we dutifully shut our eyes.  When we opened them, why, they now had the land and we had the Bible.  ~Desmond M. Tutu, "Religious Human Rights and the Bible"

Religion:  A daughter of Hope and Fear, explaining to Ignorance the nature of the Unknowable.  ~ Ambrose Bierce

The world is not a prison house but a kind of spiritual kindergarten where millions of bewildered infants are trying to spell God with the wrong blocks.  ~Edwin Arlington Robinson

The god who is reputed to have created fleas to keep dogs from moping over their situation must also have created fundamentalists to keep rationalists from getting flabby.  Let us be duly thankful for out blessings. ~Garrett Hardin

Sunday school:  a prison in which children do penance for the evil conscience of their parents.  ~H.L. Mencken

If I were not an atheist, I would believe in a God who would choose to save people on the basis of the totality of their lives and not the pattern of their words.  I think he would prefer an honest and righteous atheist to a TV preacher whose every word is God, God, God, and whose every deed is foul, foul, foul.  ~Isaac Asimov, I.  Asimov:  A Memoir

"There's a big difference between kneeling down and bending over." - Frank Zappa.

"Isn't it enough to see that a garden is beutiful without having to believe that there are fairies at the bottom of it too?" - Douglas Adams

"I do not feel obliged to believe that the same God who endowed us with sense, reason, and intellect, had intended for us to forgo their use." - Galileo Galilei

 "Atheism is a requirement for a complete human being. Religion is a crutch that is shackled to you, one you never really needed in the first place, but were convinced by others that you couldn't live without. Once you discover it's only an illusion, that it's not even a real crutch, you discard it gladly." -Brent Yaciw

"If there is a God, atheism must seem to Him as less of an insult than religion.” --Edmond de Goncourt

"The invisible and the non-existent look very much alike." --Huang Po

"Faith is a cop-out. It is intellectual bankruptcy. If the only way you can accept an assertion is by faith, then you are conceding that it can't be taken on its own merits." --Dan Barker, former evangelist

"Atheism is not a philosophy; it is not even a view of the world; it is simply an admission of the obvious. In fact, 'atheist' is a term that should not ever exist. No one ever needs to identify himself as a 'non astrologer' or a 'non-alchemist'. We do not have words for people who doubt that Elvis is still alive or that aliens traversed the galaxy only to molest ranchers and their cattle. Atheism is nothing more than the noises reasonable people make in the presence of unjustified religious beliefs. An atheist is simply a person who believes that the 260 million Americans (87 percent of the population) claiming to 'never doubt the existence of God' should be obliged to present evidence for his existence-and, indeed, for his BENEVOLENCE, given the relentless destruction of innocent human beings we witness in the world each day." --Sam Harris, "Letter to a Christian Nation"

"I don't know anyone less Jesus like than Christians." - Bill Maher

"I would never want to be the member of a group whose symbol was a guy nailed to two pieces of wood." - George Carlin"

"I have as much authority as the pope, I just don't have as many people that believe it." George Carlin

"One man's theology is another man's belly laugh." - Robert Heinlein

"History does not record anywhere at any time a religion that has any rational basis. Religion is a crutch for people not strong enough to stand up to the unknown without help. But like dandruff, most people do have a religion and spend time and money on it and seem to derive considerable pleasure from fiddling with it." - Robert Heinlein

If we go back to the beginning we shall find that ignorance and fear created the gods; that fancy, enthusiasm, or deceit adorned or disfigured them; that weakness worships them; that credulity preserves them, and that custom, respect and tyranny support them in order to make the blindness of men serve its own interests. -- Baron d'Holbach, The System of Nature 

Nature, you say, is totally inexplicable without a God. That is to say, to explain what you understand very little, you have need of a cause which you understand not at all. -- Baron d'Holbach, Good Sense

Few intelligent Christians can still hold to the idea that the Bible is an infallible Book, that it contains no linguistic errors, no historical discrepancies, no antiquated scientific assumptions, not even bad ethical standards. Historical investigation and literary criticism have taken the magic out of the Bible and have made it a composite human book, written by many hands in different ages. The existence of thousands of variations of texts makes it impossible to hold the doctrine of a book verbally infallible. Some might claim for the original copies of the Bible an infallible character, but this view only begs the question and makes such Christian apologetics more ridiculous in the eyes of the sincere man. -- Elmer Homrighausen, Christianity in America

I recall the story of the philosopher and the theologian. The two were engaged in disputation and the theologian used the old quip about a philosopher resembling a blind man, in a dark room, looking for a black cat—which wasn't there. "That may be," said the philosopher: "but a theologian would have found it." -- Julian Huxley, The Creed of a Scientific Humanist

"Religion has actually convinced people that there's an invisible man -- living in the sky -- who watches everything you do, every minute of every day. And the invisible man has a special list of ten things he does not want you to do.. And if you do any of these ten things, he has a special place, full of fire and smoke and burning and torture and anguish, where he will send you to live and suffer and burn and choke and scream and cry forever and ever 'til the end of time! ..But He loves you." - George Carlin

"When one person suffers from delusion, it is called insanity. When many people suffer from a delusion, it is called Religion."

"The God of the Old Testament is arguably the most unpleasant character in all fiction: jealous and proud of it; a petty, unjust, unforgiving control-freak; a vindictive, bloodthirsty ethnic cleanser; a misogynistic, homophobic, racist, infanticidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully."--Richard Dawkins, The God Delusion, ch. 2.

"The study of theology,  as it stands in Christian churches, is the study of nothing; it is founded on nothing; it rests on nothing; it proceeds by no authorities; it has no data; it can demonstrate nothing."--Thomas Paine, in The Age Of Reason, quoted with approval by David Mills in Atheist Universe, ch. 6. 

"The moment we admit that our beliefs are attempts to represent states of the world, we see that they must stand in right relation to the world to be valid." --Sam Harris, The End Of Faith

"Urging humans to be superhumans, on pain of death and torture, is the urging of terrible self-abasement at their repeated and inevitable failure to keep the rules."--Christopher Hitchens, god is not great, ch. 15.

"Imagine a puddle waking up one morning and thinking, 'This is an interesting world I find my self in - an interesting hole I find my self in - fits me rather neatly, doesn't it? In fact it fits me staggeringly well, must have been made to have me in it!' This is such a powerful idea that as the sun rises in the sky and the air heats up and as, gradually, the puddle gets smaller and smaller, it's still frantically hanging on to the notion that everything's going to be alright, because this world was meant to have him in it, was built to have him in it; so the moment he disappears catches him rather by surprise. I think this may be something we need to be on the watch out for." - Douglass Adams

"Find me some ghost sperm and show me how one survives rigor mortis and I will become a believer. I'm sure you'll have that evidence in short order" - Brian 37

The Bible is a book that has been read more, and examined less, than any book that ever existed. - Thomas Paine [one of my personal faves]

We must question the story logic of having an all-knowing/ all-powerful God, who creates faulty humans, and then blames them for his own mistakes. - Gene Roddenberry

Philosophy is questions that may never be answered. Religion is answers that may never be questioned. - Anonymous

With or without religion, you would have good people doing good things and evil people doing evil things. But for good people to do evil things, that takes religion. - Steven Weinberg

The God of the Old Testament is arguably the most unpleasant character in all fiction: jealous and proud of it; a petty, unjust, unforgiving control-freak; a vindictive, bloodthirsty ethnic cleanser; a misogynistic, homophobic, racist, infanticidal, genocidal, filicidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully. - Richard Dawkins

All the biblical miracles will at last disappear with the progress of science. - Matthew Arnold 

As far as I can tell from studying the scriptures, all you do in heaven is pretty much just sit around all day and praise the Lord. I don’t know about you, but I think that after the first, oh, I don’t know, 50,000,000 years of that I’d start to get a little bored. - Rick Reynolds

A lie is a lie even if everyone believes it. The truth is the truth even if nobody believes it. - David Stevens

Men rarely (if ever) manage to dream up a God superior to themselves. Most Gods have the manners and morals of a spoiled child. - Robert A Heinlein

He that will not reason is a bigot; he that cannot reason is a fool; he that dares not reason is a slave. - William Drummond

Religion does three things quite effectively: Divides people, Controls people, Deludes people. - Carlespie Mary Alice McKinney

“There are no atheists in foxholes” isn’t an argument against atheism, it’s an argument against foxholes. - James Morrow

Properly read, the bible is the most potent force for Atheism ever conceived. - Isaac Asimov

Faith does not give you the answers, it just stops you asking the questions. - Frater Ravus

If god is the alpha and the omega. The begining and the end, knows what has passed and what is to come, like it states in the bible, why do people pray and think it will make any difference. - Mark Fairclough

If we expect God to subscribe to one religion at the exclusion of all the others, then we should expect damnation as a matter of chance. This should give Christians pause when expounding their religious beliefs, but it does not. - Sam Harris

A myth is a religion in which no one any longer believes - James K. Feibleman

Just in terms of allocation of time resources, religion is not very efficient. There's a lot more I could be doing on a Sunday morning. - Bill Gates

"Everything is what it is because it got that way." -D'arcy Thompson

"We may conclude, therefore, that, in all nations, which have embraced polytheism, the first ideas of religion arose not from a contemplation of the works of nature, but from a concern with regard to the events of life, and from the incessant hopes and fears, which actuate the human mind." -Hume, The Natural History of Religion

"We find human faces in the moon, armies in the clouds; and by a natural propensity, if not corrected by experience and reflection, ascribe malice and good-will to every thing, that hurts or pleases us."--Hume, TNHR

"You can fool all of the people some of the time, and some of the people all of the time, but you cannot fool all of the people all of the time." --Abraham Lincoln

"Those to whom his word was revealed were always alone in some remote place, like Moses. There wasn't anyone else around when Mohammed got the word either. Mormon Joseph Smith and Christian Scientist, Mary Baker Eddy, had exclusive audiences with God. We have to trust them as reporters---and you know how reporters are. They'll do anything for a story." --Andy Rooney 

"Pray: To ask that the laws of the universe be annulled on behalf of a single petitioner, confessedly unworthy." - Ambroce Bierce

In a dangerous world, there will always be more people around whose prayers for their own safety have been answered than those whose prayers have not." -Nicholas Humphrey's Law of the Efficacy of Prayer

"Cults and prophets proclaiming the imminent end of the world have been with us for several millenia, and it has been another sour sort of fun to ridicule them the morning after, when they discover that their calculations were a little off. But, just as with Marxists, there are some among them who are working hard to 'hasten the inevitable,' not merely anticipating the End Days with joy in their hearts, but taking political action to bring about the conditions they think are the prerequisites for that occasion." -Dennett, Breaking the Spell, pg 338

When people thought the earth was flat, they were wrong. When people thought the earth was spherical, they were wrong. But if you think that thinking the earth is spherical is just as wrong as thinking the earth is flat, then your view is wronger than both of them put together. -- Isaac Asimov

From the point of view of a tapeworm, man was created by God to serve the appetite of the tapeworm. -- Edward Abbey

Truth does not demand belief. Scientists do not join hands every Sunday, singing, "Yes, gravity is real! I will have faith! I will be strong! I believe in my heart that what goes up, up, up must come down, down, down. Amen!" If they did, we would think they were pretty insecure about it. -- Dan Barker

Faith is the fatigue resulting from the attempt to preserve God's integrity instead of one's own. -- Matt Berry

All thinking men are atheists. — Ernest Hemingway

Lighthouses are more helpful then churches. — Benjamin Franklin

Say what you will about the sweet miracle of unquestioning faith, I consider a capacity for it terrifying and absolutely vile. — Kurt Vonnegut

A man is accepted into a church for what he believes and he is turned out for what he knows. — Samuel Clemens

The church says the earth is flat, but I know that it is round, for I have seen the shadow on the moon, and I have more faith in a shadow than in the church. — Ferdinand Magellan

"Let's face a historical truth: we have never had a "free market", we have always had government intervention in the economy, and indeed that intervention has been welcomed by the captains of finance and industry. They had no quarrel with "big government" when it served their needs." - Howard Zinn

"This would be the best of all possible worlds if there were no religion in it." - John Adams

"Lighthouses are more useful than Churches." - Benjamin Franklin

"People who don't like their beliefs being laughed at shouldn't have such funny beliefs."

"How come when it's us is an abortion and when it's a chicken is an omelet?" - George Carlin

" Why is it often that, when someone points out the lies of another person, the person who lied gets angry, rather than abashed. Never is this more apparent than when the lie pointed out is a lie to oneself, and the anger never more fierce than when the lie is one of religion." ~ G. Scott Wells

"If you could reason with religious people, there would be no religious people" - Gregory House

"Blind belief in authority is the greatest enemy of truth." - Albert Einstein

"If people are good only because they fear punishment, and hope for reward, then we are a sorry lot indeed." - Albert Einstein

"I cannot imagine a God who rewards and punishes the objects of his creation, whose purposes are modeled after our own -- a God, in short, who is but a reflection of human frailty. Neither can I believe that the individual survives the death of his body, although feeble souls harbor such thoughts through fear or ridiculous egotisms." - Albert Einstein

"The word God is for me nothing more than the expression and product of human weaknesses, the Bible a collection of honourable, but still primitive legends which are nevertheless pretty childish. No interpretation no matter how subtle can change this." - Albert Einstein

"It seems to me that the idea of a personal God is an anthropological concept which I cannot take seriously. I also cannot imagine some will or goal outside the human sphere... Science has been charged with undermining morality, but the charge is unjust. A man's ethical behavior should be based effectually on sympathy, education, and social ties and needs; no religious basis is necessary. Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death." - Albert Einstein

"If we are to believe the Bible, god created a flood that nearly wiped out all of mankind, taking genocide to epic proportions. Why then is god worshiped and Hitler, who committed genocide on a smaller scale, labeled evil for similar acts?" - Scott Williams
