We want you to do this because this conclusion is at the basis of a practical system of mental efficiency and because, as we shall at once show you, it is capable of proof by the established methods of physical science.

The fact is, one's opinion as to whether mind controls body or body makes mind-action depends altogether upon the point of view. And the first step for us to take is to agree upon the point of view we shall assume.
Two points of view are possible. One is speculative, the other practical.
