“And yet, the fact that we are no longer killing people for heresy in the West suggests that bad ideas, however sacred, cannot survive the company of good ones forever.”

“The point is that most of what we currently hold sacred is not sacred for any reason other than that it was thought sacred yesterday.”

“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.”

“If we cannot find our way to a time when most of us are willing to admit that, at the very least, we are not sure whether or not God wrote some of our books, then we need only count the days to Armageddon—because God has given us far many more reasons to kill one another than to turn the other cheek.”

“All I’m arguing for really is that we should have a conversation where the best ideas really thrive, where there’s no taboo against criticizing bad ideas, and where everyone who shows up, in order to get their ideas entertained, has to meet some obvious burdens of intellectual rigor and self-criticism and honesty—and when people fail to do that, we are free to stop listening to them. What religion has had up until this moment is a different set of rules that apply only to it, which is you have to respect my religious certainty even though I’m telling you I arrived at it irrationally.”

“The fact that my continuous and public rejection of Christianity does not worry me in the least should suggest to you just how inadequate I think your reasons for being a Christian are.”

“Moderates in every faith are obliged to loosely interpret (or simply ignore) much of their canons in the interests of living in the modern world. No doubt an obscure truth of economics is at work here: societies appear to become considerably less productive whenever large numbers of people stop making widgets and begin killing their customers and creditors for heresy. The first thing to observe about the moderate's retreat from scriptural literalism is that it draws its inspiration not from scripture but from cultural developments that have rendered many of God's utterances difficult to accept as written.”
