proved. It does not make experiments its foundation, but builds on fundamentals. In Magic if you master the fundamentals, you have the Master Key. These fundamentals become a part of you.

I don't care how many tricks you forget, if you have the principles down so well that you can recall them at a moment's notice, you can do a great variety of tricks.

Another reason I give you the Science of Magic is that I want you to be able to do other tricks besides the ones I give you. I want you to be able to originate new methods and even new tricks. You can do this easily if you really know the Science of Magic.

I have studied each lesson time and again to make sure that I give you everything to contribute to your understanding of the Science of Magic. I have chosen the trick for each lesson not because I wanted to teach you a trick, but because I wanted to teach you a principle. Each trick illustrates specifically some fundamental and I want you to practice the trick to learn the principle. Do not make learning the trick your sole aim. That is unscientific and unprofessional.

Learn the principle and you will be able to do hundreds of tricks based on the same principle, not only the trick I give you. A Magician is not a Magician because he knows tricks, but because he knows Magic -- the principles, the fundamentals.

So remember you are to become a Scientist in the Realm of Magic and consequently a real Professional. You as a Scientific Magician will stand out way above the ordinary man in the Profession -- because you have a clearly thought out, scientifically arranged course. You will have a firm foundation of Science through which you can develop and reach unbelievable success as a Magician.
