I am fascinated by religion. (That's a completely different thing from believing in it!) It has had such an incalculably huge effect on human affairs. What is it? What does it represent? Why have we invented it? How does it keep going? What will become of it? I love to keep poking and prodding at it. I've thought about it so much over the years that that fascination is bound to spill over into my writing.

[Religion] is predominantly evil and entirely deceitful, has only negative correlations statistically, and is frequently maliciously abusive physically mentally and emotionally. It has historically always obstructed education and retarded or impeded progress in whatever application it has ever touched. All the worst atrocities in history were done in the name of religion and our greatest advances were made in opposition to it. I’m an antitheist because religion is factually historically ethically and morally wrong.

I am neither a saint nor a theologian. To me, good works are more important than theology. We all know that religion has been historically, and still is today, a cause of great evil as well as great good in human affairs. We have seen terrible wars and terrible persecutions conducted in the name of religion. We have also seen large numbers of people inspired by religion to lives of heroic virtue, bringing education and medical care to the poor, helping to abolish slavery and spread peace among nations. Religion amplifies the good and evil tendencies of individual souls. Religion will always remain a powerful force in the history of our species. To me, the meaning of progress in religion is simply this, that as we move from the past to the future the good works inspired by religion should more and more prevail over the evil.

The starting point is the recognition that throughout history, religion has been a cause of bloodshed, and it remains so today. Because religion has contributed to the world's problems, it must develop specific and practical ways to help solve those problems.

The spectacle of what is called religion, or at any rate organised religion, in India and elsewhere, has filled me with horror and I have frequently condemned it and wished to make a clean sweep of it. Almost always it seemed to stand for blind belief and reaction, dogma and bigotry, superstition, exploitation and the preservation of vested interests.

Religions have done far more damage over the centuries than good. Religion may help individuals to bear hard times and trouble and loss, but institutionalized religion of all stripes quickly becomes dangerous. Established religion always seems to breed a them vs us mentality that has lead to crusades, pogroms, ethnic cleansing, the Inquisition, genocide, civil war, and legal discrimination.

One of the greatest tragedies in mankind's entire history may be that morality was hijacked by religion.

The history of religions reaches down and makes contact with that which is essentially human: the relation of man to the sacred. The history of religions can play an extremely important role in the crisis we are living through. The crises of modern man are to a large extent religious ones, insofar as they are an awakening of his awareness to an absence of meaning.

There is a dark side to religious devotion that is too often ignored or denied. As a means of motivating people to be cruel or inhumane, there may be no more potent force than religion. When the subject of religiously inspired bloodshed comes up, many Americans immediately think of Islamic fundamentalism, which is to be expected in the wake of 911. But men have been committing heinous acts in the name of God ever since mankind began believing in deities, and extremists exist within all religions. Muhammad is not the only prophet whose words have been used to sanction barbarism; history has not lacked for Christians, Jews, Hindus, Sikhs, and even Buddhists who have been motivated by scripture to butcher innocents. Plenty of these religious extremist have been homegrown, corn-fed Americans.

The danger of religious faith is that it allows otherwise normal human beings to reap the fruits of madness and consider them holy. Because each new generation of children is taught that religious propositions need not be justified in the way that all others must, civilization is still being besieged by the armies of the preposterous. We are, even now, killing ourselves over ancient literature. Who would have thought something so tragically absurd could be possible?

Religion carries two sorts of people in two entirely opposite directions: the mild and gentle people it carries towards mercy and justice; the persecuting people it carries into fiendish sadistic cruelty. Mind you, though this may seem to justify the eighteenth-century Age of Reason in its contention that religion is nothing but an organized, gigantic fraud and a curse to the human race, nothing could be farther from the truth. It possesses these two aspects, the evil one of the two appealing to people capable of naïve hatred; but what is actually happening is that when you get natures stirred to their depths over questions which they feel to be overwhelmingly vital, you get the bad stirred up in them as well as the good; the mud as well as the water. It doesn't seem to matter much which sect you have, for both types occur in all sects....

"Religion is, as I say, something universal and something human, and something impossible to eradicate, nor would I want to eradicate it. I am a religious person, although I am not a believer.

Religion is at its best when it is a long way from political power. The founder of the Christian religion — or, the founders of the Christian religion, Jesus and St. Paul — were both clear about this. "Blessed are the meek." "You shall love your neighbor as yourself." St. Paul is perfectly clear that the highest Christian virtue is charity, not patriotism, not martial valor, not exalting your class, your group, your race above others, but charity. That's the highest virtue. When religion remembers that and acts accordingly, it does good.

But religion, at various points in human history, notably the history of western Europe and the history of some parts of the Middle East more recently, has acquired political power, and put its hands on the levers of social authority. It decides who shall live and who shall die. It decides how we shall dress, what we shall be allowed to read, whether we shall go to war, and so on. When religion acquires that power, it goes bad very rapidly."

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

Religion is a by-product of fear. For much of human history it may have been a necessary evil, but why was it more evil than necessary? Isn’t killing people in the name of god a pretty good definition of insanity?
