“Your least favorite virtue, or nominee for the most overrated one? Faith. Closely followed—in view of the overall shortage of time—by patience.”

“You don’t get to advertise all the good that your religion does without first scrupulously subtracting all the harm it does and considering seriously the question of whether some other religion, or no religion at all, does better.”

“Civilization will not attain to its perfection until the last stone from the last church falls on the last priest.”

“I suppose that one reason I have always detested religion is its sly tendency to insinuate the idea that the universe is designed with ‘you’ in mind or, even worse, that there is a divine plan into which one fits whether one knows it or not. This kind of modesty is too arrogant for me.”

“A young man who wishes to remain a sound atheist cannot be too careful of his reading.”

“The more I learn about the universe, the less convinced I am that there’s any sort of benevolent force that has anything to do with it, at all.”

“Many religions now come before us with ingratiating smirks and outspread hands, like an unctuous merchant in a bazaar. They offer consolation and solidarity and uplift, competing as they do in a marketplace. But we have a right to remember how barbarically they behaved when they were strong and were making an offer that people could not refuse.”

“I don’t want to believe. I want to know.”

“The difference between faith and insanity is that faith is the ability to hold firmly to a conclusion that is incompatible with the evidence, whereas insanity is the ability to hold firmly to a conclusion that is incompatible with the evidence.”

“We keep on 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.”

“What is it you most dislike? Stupidity, especially in its nastiest forms of racism and superstition.”

“And here is the point, about myself and my co-thinkers. Our belief is not a belief. Our principles are not a faith. We do not rely solely upon science and reason, because these are necessary rather than sufficient factors, but we distrust anything that contradicts science or outrages reason. We may differ on many things, but what we respect is free inquiry, openmindedness, and the pursuit of ideas for their own sake.”

“Science is not only compatible with spirituality; it is a profound source of spirituality. When we recognize our place in an immensity of light‐years and in the passage of ages, when we grasp the intricacy, beauty, and subtlety of life, then that soaring feeling, that sense of elation and humility combined, is surely spiritual. So are our emotions in the presence of great art or music or literature, or acts of exemplary selfless courage such as those of Mohandas Gandhi or Martin Luther King, Jr. The notion that science and spirituality are somehow mutually exclusive does a disservice to both.”

“I am an atheist, out and out. It took me a long time to say it. I’ve been an atheist for years and years, but somehow I felt it was intellectually unrespectable to say one was an atheist, because it assumed knowledge that one didn’t have. Somehow, it was better to say one was a humanist or an agnostic. I finally decided that I’m a creature of emotion as well as of reason. Emotionally, I am an atheist. I don’t have the evidence to prove that God doesn’t exist, but I so strongly suspect he doesn’t that I don’t want to waste my time.”

“One would go mad if one took the Bible seriously; but to take it seriously one must be already mad.”
