The exact information and rational method of teaching which Mr. Louden is seeking, has heretofore been wanting in health-culture literature.

Many, indeed, stand ready and willing to show the way to physical, mental and moral perfection. Hundreds, yes, thousands, of different cults, isms, teachers, books and periodicals treat of these subjects, but their teachings are so manifold, so contradictory and confusing, that one becomes bewildered amid the ever increasing testimony. As is often the case in the study of complicated subjects, the more one reads and the more one hears, the less one knows. I believe that no one has described more strikingly this state of general perplexity than Mr. Louden in his excellent letter.

Nevertheless, these simple fundamental laws and principles really exist. They must exist, because everything in Nature, including the processes of health, of disease and cure, of birth, of life and death, are subject to law and order.

Allopathy, or Old School Medical Science, admits that it does not know these fundamental principles; that it reasons, not from underlying causes, but from external symptoms and personal experiences. It is, therefore, self-confessedly full of doubts, errors and confusion; in short, empirical--and necessarily, a failure.

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.
