When considering the truth of a proposition, one is either engaged in an honest appraisal of the evidence and logical arguments, or one isn't. Religion is one area of our lives where people imagine that some other standard of intellectual integrity applies.

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.

Words like 'God' and 'Allah' must go the way of 'Apollo' and 'Baal' or they will unmake our world.

Every one of the world's "great" religions utterly trivializes the immensity and beauty of the cosmos. Books like the Bible and the Koran get almost every significant fact about us and our world wrong. Every scientific domain -- from cosmology to psychology to economics -- has superseded and surpassed the wisdom of Scripture. Everything of value that people get from religion can be had more honestly, without presuming anything on insufficient evidence. The rest is self-deception, set to music.

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.

Spiritual life can certainly follow the pattern one sees in the fake martial arts, with most teachers making nebulous and magical claims that never get tested, while their students derange themselves with weird ideas, empty rituals, and other affectations.

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.
