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

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

There's something about the Houdini act that is not always made clear - about the escape act in general.

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.

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.

Feeling better is not actually being better.

Nature doesn't cheat - people do.
