“When the stakes are this high- when calling God by the right name can make the difference between eternal happiness and eternal suffering, it is impossible to respect the beliefs of others who don't believe as you do.”

“If faith is what you have to go on, if faith is the link between your beliefs and the world at large, your beliefs are very likely to be wrong. Beliefs can be right or wrong. If you believe you can fly, that belief is only true if indeed you can fly. Somebody who thinks he can fly, and is wrong about it, will eventually discover there's a problem with his view of the world.”

“It is time we realize that belief is not a private matter. As a man believes, so he will act. Believe that you are a member of a chosen people, awash in the salacious exports of an evil culture that is turning your children away from God, believe that you will be rewarded with an eternity of unimaginable delights by dealing death to these infidels—and flying a plane into a building is only a matter of being asked to do it.”

“Incompatible religious doctrines have balkanized our world into separate moral communities, and these divisions have become a continuous source of bloodshed. Indeed, religion is as much a living spring of violence today as it has been at any time in the past. The recent conflicts in Palestine (Jews vs. Muslims), the Balkans (Orthodox Serbians vs. Catholic Croatians; Orthodox Serbians vs. Bosnian and Albanian Muslims), Northern Ireland (Protestants vs. Catholics), Kashmir (Muslims vs. Hindus), Sudan (Muslims vs. Christians and animists), Nigeria (Muslims vs. Christians), Ethiopia and Eritrea (Muslims vs. Christians), Sri Lanka (Sinhalese Buddhists vs. Tamil Hindus), Indonesia (Muslims vs. Timorese Christians), Iran and Iraq (Shiite vs. Sunni Muslims), and the Caucasus (Orthodox Russians vs. Chechen Muslims; Muslim Azerbaijanis vs. Catholic and Orthodox Armenians) are merely a few cases in point. These are places where religion has been the explicit cause of literally millions of deaths in recent decades.Why is religion such a potent source of violence? There is no other sphere of discourse in which human beings so fully articulate their differences from one another, or cast these differences in terms of everlasting rewards and punishments. Religion is the one endeavor in which us–them thinking achieves a transcendent significance. If you really believe that calling God by the right name can spell the difference between eternal happiness and eternal suffering, then it becomes quite reasonable to treat heretics and unbelievers rather badly. The stakes of our religious differences are immeasurably higher than those born of mere tribalism, racism, or politics.”

“Once a person believes - really believes - that certain ideas can lead to eternal happiness, or to its antithesis, he cannot tolerate the possibility that the people he loves might be led astray by the blandishments of unbelievers. Certainty about the next life is simply incompatible with tolerance in this one.”

“What we do in every other area of our lives (other than religion), is, rather than respect somebody's beliefs, we evaluate their reasons.”

“our moral reasoning is plagued by two illusions. The first illusion can be called the wag-the-dog illusion: We believe that our own moral judgment (the dog) is driven by our own moral reasoning (the tail). The second illusion can be called the wag-theother-dog's-tail illusion: In a moral argument, we expect the successful rebuttal of an opponent's arguments to change the opponent's mind. Such a belief is like thinking that forcing a dog's tail to wag by moving it with your hand will make the dog happy.”
