To speak plainly and truthfully about the state of our world - to say, for instance, that the Bible and the Koran both contain mountains of life-destroying gibberish - is antithetical to tolerance as moderates currently conceive it. But we can no longer afford the luxury of such political correctness. We must finally recognize the price we are paying to maintain the iconography of our ignorance.

Unreason is now ascendant in the United States—in our schools, in our courts, and in each branch of the federal government.

We read the Golden Rule and judge it to be a brilliant distillation of many of our ethical impulses. And then we come across another of God’s teachings on morality: if a man discovers on his wedding night that his bride is not a virgin, he must stone her to death on her father’s doorstep (Deuteronomy 22:13-21).

Imagine a world in which generations of human beings come to believe that certain films were made by God or that specific software was coded by him. Imagine a future in which millions of our descendants murder each other over rival interpretations of Star Wars or Windows 98. Could anything -- anything -- be more ridiculous? And yet, this would be no more ridiculous than the world we are living in.

Tell a devout Christian that his wife is cheating on him, or that frozen yogurt can make a man invisible, and he is likely to require as much evidence as anyone else, and to be persuaded only to the extent that you give it. Tell him that the book he keeps by his bed was written by an invisible deity who will punish him with fire for eternity if he fails to accept its every incredible claim about the universe, and he seems to require no evidence what so ever.

If our well-being depends upon the interaction between events in our brains and events in the world, and there are better and worse ways to secure it, then some cultures will tend to produce lives that are more worth living than others; some political persuasions will be more enlightened than others; and some world views will be mistaken in ways that cause needless human misery.

For nearly a century, the moral relativism of science has given faith-based religion--that great engine of ignorance and bigotry--a nearly uncontested claim to being the only universal framework for moral wisdom. As a result, the most powerful societies on early spend their time debating issues like gay marriage when they should be focused on problems like nuclear proliferation, genocide, energy security, climate change, poverty, and failing schools.
