Many teachers of Nature Cure, Hygiene and Health cults have stumbled accidentally upon some of the natural laws and true methods of healing, but have failed to grasp and to formulate the broad underlying principles. For this reason they are often partly right and partly wrong and very apt to overdo certain methods to the neglect of others just as effective and essential, or even more so. I shall endeavor in these volumes to formulate and elucidate some of the fundamental laws and principles underlying the phenomena of life and death, health, disease and cure, and shall try to ascertain in the light of these laws how much of truth and how much of error, how much of usefulness and how much of harmfulness there may be contained in the various theories and systems of living and of healing.
