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.

There exists in society a very special class of persons that I have always referred to as the Believers. These are folks who have chosen to accept a certain religion, philosophy, theory, idea or notion and cling to that belief regardless of any evidence that might, for anyone else, bring it into doubt. They are the ones who encourage and support the fanatics and the frauds of any given age. No amount of evidence, no matter how strong, will bring them any enlightenment. They are the sheep who beg to be fleeced and butchered, and who will battle fiercely to preserve their right to be victimized.

Expose every belief to the light of reason, discourse, facts, scientific observations; question everything, be sceptical because this is the only chance at life you will ever get.

The conjuror or con man is a very good provider of information. He supplies lots of data, by inference or direct statement, but it's false data. Scientists aren't used to that scenario. An electron or a galaxy is not capricious, nor deceptive; but a human can be either or both.

Science is best defined as a careful, disciplined, logical search for knowledge about any and all aspects of the universe, obtained by examination of the best available evidence and always subject to correction and improvement upon discovery of better evidence. What's left is magic. And it doesn't work.

I am in a very peculiar business: I travel all over the world telling people what they should already know.
