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.

It's not so much religion per se, it's false certainty that worries me, and religion just has more than its fair share of false certainty or dogmatism. I'm really concerned when I see people pretending to know things they clearly cannot know.

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.

We must continually remind ourselves that there is a difference between what is natural and what is actually good for us.

As a man believes, so he will act.

It is time we recognized that belief is not a private matter; it has never been merely private. In fact, beliefs are scarcely more private than actions are, for every belief is a fount of action in potential.

It is also true that the less competent a person is in a given domain, the more he will tend to overestimate his abilities. This often produces an ugly marriage of confidence and ignorance that is very difficult to correct for.
