All the phases of the process of development of the medical science, including those of the earliest periods of civilization, have in their way of understanding the causal nature of diseases that one thing in common that the diseases, owing to external causes, enter into the human body and thus, by force of a necessary or at least unavoidable law, disturb it in its existence, cause it pain and at last destroy it. Even modern medical science, no matter how scientifically enlightened it pretends to be, has not quite turned away from this basic note of demoniac interpretation. In fact, the most modern achievement, bacteriology, rejoices over every newly discovered bacillus as a further addition to the army of beings whose accepted task it is to endanger the life of man.

Looking at it from a philosophical standpoint, this interpretation differs from the mediaeval superstition and the period of fetishism only in the supplemental name. Formerly it was an "evil spirit," which imagination went so far as to believe in "satanic personages;" now this same dangerous monster is a microscopically visible being whose existence has been proven beyond any doubt.

The matter, it is true, has still a great drawback in the so-called "disposition"--a fine word!--but what we really are to understand by it, nobody has ever told us. All the tests on animals, with their symptom-reactions, do not prove anything sure, because these occur only by means of injection into the blood-circulation and never by introduction into the digestive channel through the mouth.

There is something true in the conception of "external invasion" of a disease, as well as in heredity, however not in the sense that the invader is a spirit (demon) hostile to life, or a microscopic being (bacillus); but all diseases without exception, even the hereditary, are caused-- disregarding a few other unhygienic causes--by biologically wrong, "unnatural" food and by each ounce of over-nourishment, only and exclusively.

First of all I maintain that in all diseases without exception there exists a tendency by the organism to secrete mucus, and in case of a more advanced stage--pus (decomposed blood). Of course every healthy organism must also contain a certain mucus--lymph, a fatty substance of the bowels, etc., of a mucus nature.) Every expert will admit this in all catarrhalic cases, from a harmless cold in the nose to inflammation of the lungs and consumption, as well as in epilepsy (attacks showing froth at the mouth, mucus). Where this secretion of mucus does not show freely and openly, as in cases of ear, eye, skin or stomach trouble, heart diseases, rheumatism, gout, etc., even in all degrees of insanity, is mucus the main factor of the illness, the natural secretive-organs not being able to cope with it any longer, the mucus entering the blood and causing at the respective spot where the vessel-system is probably contracted owing to an over-cooling (cold), etc., heat, inflammation, pain, fever.

We need only to give a patient of any-kind nothing but "mucusless" food, for instance fruit or even nothing but water or lemonade: we then find that the entire digestive energy, freed for the first time, throws itself upon the mucus-matters, accumulated since childhood and frequently hardened, as well as on the "pathologic beds" formed therefrom. And the result? With unconditional certainty this mucus which I mark as the common basic and main cause of all diseases will appear in the urine and in the excrements. If the disease is already somewhat advanced so that in some spot, even in the innermost interior, there have appeared pathologic beds, i.e. decomposed cellular tissues, then pus is also being secreted. As soon as the introduction of mucus by means of "artificial food," fat meat, bread, potatoes, farinaceous products, rice milk, etc., ceases, the blood-circula tion attacks the mucus and the pus of the body themselves and secretes them through the urine, and in the case of heavily infected bodies, even through all the openings at their command as well as through the mucus membranes.

If potatoes, grain-meal, rice or the respective meat-materials are being boiled long enough, we receive a jellylike slime (mucus) or paste used by bookbinders and carpenters. This mucus substance soon becomes sour, ferments, and forms a bed for fungi, moulds and bacilli. In the digestion, which is nothing else but a boiling, a combustion, this slime or paste is being secreted in the same manner, for the blood can use only the ex-digested sugar transformed from starch. The secreted matter, the superfluous product, i.e., this paste or slime is a foreign matter to the body and is being completely excreted in the beginning. It is, therefore, easy to understand that in the course of life the intestines and the stomach are gradually being pasted and slimed up to such an extent that this paste of floral and this slime of faunal origin turn into fermentation, clog up the blood-vessels and finally decompose the stagnating blood. If figs, dates or grapes are boiled down thick enough we also receive a pap which, however, does not turn to fermentation and never secretes slime, and which nobody calls slime, but which is called syrup. Fruit-sugar, the most important thing for the blood, is also sticky, it is true, but is being completely used up by the body as the highest form of fuel, and leaves for excretion only traces of cellulose, which, not being sticky, is promptly excreted and does not ferment. Boiled-down sugar, owing to its resistance against fermentation, is even used for the preservation of food.

Each healthy or sick person deposits on the tongue a stinking mucus as soon as he reduces his food or fasts. This occurs also on the mucous membrane of the stomach, of which the tongue is an exact copy. In the first stool after the fasting this mucus makes its appearance.

I recommend to the physicians and searchers to test my claims by way of experiments which alone are entitled to real scientific recognition. The experiment, the question put to nature, is the basis of all natural science and reveals the infallible truth, no matter whether it is stated by me or somebody else. Furthermore, I recommend to those who are brave enough to test on their own bodies the following experiments which I undertook on mine. They will receive the same answer from nature, i. e., from their organism, provided that the latter be sound in my sense. "Exact" to a certain degree reacts only the clean sound, mucusless organism. After a two years' strict fruit- diet with intercalated fasting cures, I had attained a degree of health which is simply not imaginable nowadays and which allowed of my making the following experiments:
