No matter how smart or well-educated you are, you can be deceived.

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

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.

Nature doesn't cheat - people do.

We have fought long and hard to escape from medieval superstition. I, for one, do not wish to go back.

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.

[Psychics] use exactly the same gimmicks that we magicians do - the same physical methods, the same psychological methods - and they effectively and profoundly deceive millions of people around the earth, to their detriment.
