I can go into a lab and fool the rear ends off any group of scientists.

No evidence against a firmly-held belief, no matter how good or abundant it may be, will sway the true believer.

A lot of people hate my skepticism, and I think I understand why. The psychics offer wonders and endless possibilities in a world that often seems difficult and mundane. They promise health, wealth, wisdom, eternal life. But if you examine the record, it's not the psychics but the hard-nosed scientists who have actually delivered the things that improve human life. And, to me, science describes a world far more interesting than any psychic fantasy. It's a good world -- not perfect -- but it's ours. So we'd better learn to live with it, the way it is.

I believe in the basic goodness of my species, because that appears to be a positive tactic and quality that leads to better chances of survival- and in spite of our foolishness, we seem to have survived.

Everyone who believes in telekinesis, raise my hand.

The market for nonsense is infinite.

Feeling better is not actually being better.
