BERTRAND RUSSELL
Why I Am Not a Christian

That is the idea -- that we should all be wicked if we did not hold to the Christian religion. It seems to me that the people who have held to it have been for the most part extremely wicked. You find this curious fact, that the more intense has been the religion of any period and the more profound has been the dogmatic belief, the greater has been the cruelty and the worse has been the state of affairs. In the so-called ages of faith, when men really did believe the Christian religion in all its completeness, there was the Inquisition, with all its tortures; there were millions of unfortunate women burned as witches; and there was every kind of cruelty practiced upon all sorts of people in the name of religion.

You find as you look around the world that every single bit of progress in humane feeling, every improvement in the criminal law, every step toward the diminution of war, every step toward better treatment of the colored races, or every mitigation of slavery, every moral progress that there has been in the world, has been consistently opposed by the organized churches of the world.

I say quite deliberately that the Christian religion, as organized in its churches, has been and still is the principal enemy of moral progress in the world.

You may think that I am going too far when I say that that is still so. I do not think that I am. Take one fact. You will bear with me if I mention it. It is not a pleasant fact, but the churches compel one to mention facts that are not pleasant. Supposing that in this world that we live in today an inexperienced girl is married to a syphilitic man; in that case the Catholic Church says, "This is an indissoluble sacrament. You must endure celibacy or stay together. And if you stay together, you must not use birth control to prevent the birth of syphilitic children." Nobody whose natural sympathies have not been warped by dogma, or whose moral nature was not absolutely dead to all sense of suffering, could maintain that it is right and proper that that state of things should continue.

That is only an example. There are a great many ways in which, at the present moment, the church, by its insistence upon what it chooses to call morality, inflicts upon all sorts of people undeserved and unnecessary suffering. And of course, as we know, it is in its major part an opponent still of progress and improvement in all the ways that diminish suffering in the world, because it has chosen to label as morality a certain narrow set of rules of conduct which have nothing to do with human happiness; and when you say that this or that ought to be done because it would make for human happiness, they think that has nothing to do with the matter at all. What has human happiness to do with morals? The object of morals is to not make people happy.

ROBERT G. INGERSOLL
About The Holy Bible

If anything is, or can be, certain, the writers of the Bible were mistaken about creation, astronomy, geology; about the causes of phenomena, the origin of evil and the cause of death.

Now, it must be admitted that if an Infinite Being is the author of the Bible, he knew all sciences, all facts, and could not have made a mistake.

If, then, there are mistakes, misconceptions, false theories, ignorant myths and blunders in the Bible, it must have been written by finite beings; that is to say, by ignorant and mistaken men.

Nothing can be clearer than this.

Perfect title.

JOSEPH LEWIS
An Atheist Manifesto

You are to make up your mind whether it is to be God or man. Whether you are to be free or a slave. Whether it is to be progress or stagnation.

As long as man loves a phantom in the sky more than he loves his fellow man, there will never be peace upon this earth; so long as man worships a Tyrant as the "Fatherhood of God," there will never be a "Brotherhood of Man."

You must make the choice, you must come to the decision. Is it to be God or Man? Churches or Homes—preparation for death or happiness for the living?

If ever man needed an example of the benefit of the one against the other, he need but read the pages of history for proof of how religion retarded progress and provoked hatred among the children of men.

When theology ruled the world, man was a slave. The people lived in huts and hovels. They were clad in rags and skins; they devoured crusts and gnawed bones; the priests wore garments of silk and satin; carried mitres of gold and precious stones, robbed the poor and lived upon the fat of the land!

Here and there a brave man appeared to question their authority. These martyrs to intellectual emancipation slowly and painfully broke the spell of superstition and ushered in the Age of Reason and the Dawn of Science.

Man became the only god that man can know. He no longer fell upon his knees in fear. He began to enjoy the fruits of his own labor.

He discovered a way to relieve himself from the drudgery of continuous toil; he began to enjoy a few comforts of life—and for the first time upon this earth he found a few moments for happiness. It is far more important to learn how to live than to learn how to pray.

A new day and a new era dawned for him. His labors produced enormous dividends. He looked at the sky for the first time and saw that it was blue! He searched the heavens and found no God. He no longer feared the manifestations of nature.

ROBERT G. INGERSOLL
The Liberty of Man, Woman, and Child

When the great ship containing the hopes and aspirations of the world, when the great ship freighted with mankind goes down in the night of death, chaos and disaster, I am willing to go down with the ship. I will not be guilty of the ineffable meanness of paddling away in some orthodox canoe. I will go down with the ship, with those who love me, and with those whom I have loved.

If there is a God who will damn his children forever, I would rather go to hell than to go to heaven and keep the society of such an infamous tyrant.

I make my choice now. I despise that doctrine. It has covered the cheeks of this world with tears. It has polluted the hearts of children, and poisoned the imaginations of men. It has been a constant pain, a perpetual terror to every good man and woman and child. It has filled the good with horror and with fear; but it has had no effect upon the infamous and base. It has wrung the hearts of the tender; it has furrowed the cheeks of the good. This doctrine never should be preached again.

What right have you, sir, Mr. Clergyman, you, minister of the gospel, to stand at the portals of the tomb, at the vestibule of eternity, and fill the future with horror and with fear? I do not believe this doctrine: neither do you. If you did, you could not sleep one moment. Any man who believes it, and has within his breast a decent, throbbing heart, will go insane. A man who believes that doctrine and does not go insane has the heart of a snake and the conscience of a hyena.

Suggesting anything else is pure delusion.

ANAÏS NIN

The Diary of Anaïs Nin, Vol. 4: 1944-1947

The important task of literature is to free man, not to censor him, and that is why Puritanism was the most destructive and evil force which ever oppressed people and their literature: it created hypocrisy, perversion, fears, sterility.

CHRISTOPHER HITCHENS
God Is Not Great: How Religion Poisons Everything

Evolution has meant that our prefrontal lobes are too small, our adrenal glands are too big, and our reproductive organs apparently designed by committee; a recipe which, alone or in combination, is very certain to lead to some unhappiness and disorder.

CHRISTOPHER HITCHENS

Religion is a totalitarian belief. It is the wish to be a slave. It is the desire that there be an unalterable, unchallengeable, tyrannical authority who can convict you of thought crime while you are asleep, who can subject you to total surveillance around the clock every waking and sleeping minute of your life, before you're born and, even worse and where the real fun begins, after you're dead. A celestial North Korea. 

Who wants this to be true? Who but a slave desires such a ghastly fate? I've been to North Korea. It has a dead man as its president, Kim Jong-Il is only head of the party and head of the army. He's not head of the state. That office belongs to his deceased father, Kim Il-Sung. It's a necrocracy, a thanatocracy. It's one short of a trinity I might add. The son is the reincarnation of the father. It is the most revolting and utter and absolute and heartless tyranny the human species has ever evolved. 

But at least you can fucking die and leave North Korea!

This little light of mine.

CHRISTOPHER HITCHENS

We keep being told that religion, whatever its imperfections, at least instills morality. On every side there is conclusive evidence that the contrary is the case and that faith causes people to be more mean, more selfish, and - perhaps above all - more stupid.

Religion is poison.

Religion kills.

OLAF STAPLEDON
Last and First Men

There is much in this vision that will remind you of your mystics; yet between them and us there is far more difference than similarity, in respect both of the matter and the manner of our thought. For while they are confident that the cosmos is perfect, we are sure only that it is very beautiful. While they pass to their conclusion without the aid of intellect, we have used that staff every step of the way. Thus, even when in respect of conclusions we agree with your mystics rather than your plodding intellectuals, in respect of method we applaud most your intellectuals; for they scorned to deceive themselves with comfortable fantasies.

YUVAL NOAH HARARI
Sapiens: A Brief History of Humankind

Is there anything more dangerous than dissatisfied and irresponsible gods who don’t know what they want?

Religion Kills. Religion is pure evil.

There's nothing else to say about it.
