It is the inevitable effect of religion on public policy that makes it a matter of public concern. Advocates of religiosity extol the virtues or moral habits that religion is supposed to instill in us. But we should be equally concerned with the intellectual habits it discourages.

I do what I do because I have a compulsion to hold forth. I don't spend a lot of time, if any, thinking about the effect my work is going to have on the world. And I have an abiding mistrust of people who think that they're going to change the world. I think that people who think that they're going to change the world are the kind of people who put bombs on airplanes.

The dissemination of pseudoscience, including such things as the fascination with near-death experiences and the growing belief by Americans -- 34 percent of them -- in reincarnation are dangerous. They help to break down the standards of reason.

Faith is not a function of stupidity but a frequent cause of it.

The scarcest resource these days is reason. What's certainly striking about American culture today is the great hostility toward science and the decline of respect for rational scientific thinking. People seem to think that we are ruled by the scientific method and that we overvalue reason. If there was ever a period when we overvalued reason, I think that it was probably extremely brief. What I see now is a great deal of superstition, as much superstition as there has ever been. There are probably more people who believe in guardian angels than who understand the law of gravity.

Under the rubric of religious freedom, we respect the right to worship differently much more than the right to worship not at all.

There are only two states of being in the world of codependency - recovery and denial.
