As its title asserts, the book deals with science, not speculation. The monistic theory of the universe—the theory that matter, mind, consciousness, and life are all manifestations of one Substance—is now accepted by most thinkers; and if you accept this theory, you cannot deny the logical conclusions you will find herein. Best of all, the methods of thought and action prescribed have been tested by the author in his own case, and in the case of hundreds of others during twelve years of practice, with continuous and unfailing success. I can say of the Science of Being Well that it works; and that wherever its laws are complied with, it can no more fail to work than the science of geometry can fail to work. If the tissues of your body have not been so destroyed that continued life is impossible, you can get well; and if you will think and act in a Certain Way, you will get well.
