Now, I know it is natural, and doubtless best, that there should be a difference of opinion on any question, but at the same time, if any movement is to be crowned with great success, there should be some underlying principles upon which all should agree, and these should be pressed to the forefront, so as to attract and hold the attention of the people, in place of the divergent details upon which they disagree. If these fundamental laws and principles are thoroughly studied and well defined, it may be found that they would explain the discrepancies between the different theories, and that under certain conditions, one plan is best, and that under different conditions another plan is more applicable, etc. The pushing of these fundamental principles to the front would also tend to correct errors into which the different theorists have fallen, and would certainly tend to make the different theories more homogeneous and more easily understood by people in general, than at present.

In my opinion, the general fundamental principles of life and health are what people need to understand more than anything else. Without this, most of the details will be meaningless or at least confusing dogmas. I don't mean by these fundamental principles the details of anatomy, or, for that matter, the details of anything else, but the general rules governing life and death, so that people may know which way they, are tending, and may understand the many illusions with which life and death, as well as all else in nature are beset.

The present volume and others of the "Nature Cure Series" which are to follow are an attempt to answer Mr. Louden's inquiry and to formulate and elucidate the fundamental laws of health, disease and cure for which he and many others have been vainly seeking. Who among you at some time or another, has not thought and felt like Mr. Louden and in doubt and perplexity voiced Pilate's query,

What Is Truth?

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.
