"Magic is the art of entertaining with tricks that are in apparent violation of natural law. The principles of deception that the Magicians use are psychological; the methods are manipulative and mechanical. The psychological principles are misdirection, suggestion, imitation, and concealment. The spectators do not see everything that happens, and they believe they see things that do not happen. Such faulty perception leads to false assumptions, fallacious logic, and, in the end, to the conclusion that the performer has achieved an impossible result."
– Funk and Wagnall’s New Encyclopedia
"There’s a moment in your life when you realize the difference between illusion and reality and that you’re being lied to….Santa Claus. The Easter Bunny. After my mother told me that there was no Santa Claus, I made up an entirely fictitious girl in my classroom and told my mother stories about her….If you’re sufficiently preoccupied with the power of a lie, a falsehood, an illusion, you remain interested in magic tricks."
