Organon aphorism §19
Now, as DISEASES are nothing more than ALTERATIONS IN THE STATE OF HEALTH OF THE HEALTHY INDIVIDUAL which express themselves by morbid signs, and the CURE is also only possible by a CHANGE TO THE HEALTHY CONDITION OF THE STATE OF HEALTH OF THE DISEASED INDIVIDUAL, it is very evident that MEDICINES could never cure diseases if they did not possess the power of altering man's state of health which depends on sensations and functions; indeed, that their curative power must be owing SOLELY to this power they possess of altering man's state of health.
Organon aphorism §20
This spirit-like power to alter man's state of health which lies hidden in the inner nature of medicines can in itself never be discovered by us by a mere effort of reason; it is only by experience of the phenomena it displays when acting on the state of health of man that we can become clearly cognizant of it.
Organon aphorism §21
Now, as it is undeniable that the curative principle in medicines is not in itself perceptible, and as in pure experiments with medicines conducted by the most accurate observers, nothing can be observed that can constitute them medicines or remedies except that power of causing distinct alterations in the state of health of the human body, and particularly in that of the HEALTHY INDIVIDUAL, and of exciting in him various definite morbid symptoms; so it follows that when medicines act as remedies, they can only bring their curative property into play by means of this their power of altering man's state of health by the production of peculiar symptoms; and that, therefore, we have only to rely on the morbid phenomena which the medicines produce in the healthy body as the sole possible revelation of their in-dwelling curative power, in order to learn what disease-producing power, and at the same time what disease-curing power, each individual medicine possesses.
Organon aphorism §22
But as nothing is to be observed in diseases that must be removed in order to change them into health besides the totality of their signs and symptoms, and likewise medicines can show nothing curative besides their tendency to produce morbid symptoms in healthy persons and to remove them in diseased persons; it follows, on the one hand, that medicines only become remedies and capable of annihilating diseases, because the medicinal substance, by exciting certain effects and symptoms, that is to say, by producing a certain artificial morbid state, removes and abrogates the symptoms already present, to wit, the natural morbid state we wish to cure. On the other hand, it follows that, for the totality of the symptoms of the disease to be cured, that medicine must be sought which (according as experience shall prove whether the morbid symptoms are most readily, certainly, and permanently removed and changed into health by SIMILAR or OPPOSITE medicinal symptoms ( 12 ) proved to have the greatest tendency to produce similar or opposite symptoms.
Organon aphorism §23
All pure experience, however, and all accurate research convince us that persistent symptoms of disease are far from being removed and annihilated by OPPOSITE symptoms of medicines (as in the ANTIPATHIC, ENANTIOPATHIC or PALLIATIVE method), that, on the contrary, after transient, apparent alleviation, they break forth again, only with increased intensity, and become manifestly aggravated (see (§58-62) and (§69)).
Organon aphorism §24
There remains, therefore, no other mode of employing medicines in diseases that promises to be of service besides the homeopathic, by means of which we seek, for the totality of the symptoms of the case of disease, a medicine which among all medicines (whose pathogenetic effects are known from having been tested in healthy individuals) has the power and the tendency to produce an artificial morbid state most similar to that of the case of disease in question.
Organon aphorism §25
Now, however, in all careful trials, pure experience, ( 13 ) the sole and infallible oracle of the healing art, teaches us that actually that medicine which, in its action on the healthy human body, has demonstrated its power of producing the greatest number of symptoms SIMILAR to those observable in the case of disease under treatment, does also, in doses of suitable potency and attenuation, rapidly, radically and permanently remove the totality of the symptoms of this morbid state, that is to say (§6-16), the whole disease present, and change it into health; and that all medicines cure, without exception, those diseases whose symptoms most nearly resemble their own, and leave none of them uncured.
Organon aphorism §26
This depends on the following homeopathic law of nature which was sometimes, indeed, vaguely surmised but not hitherto fully recognized, and to which is due every real cure that has ever taken place:
A WEAKER DYNAMIC AFFECTION IS PERMANENTLY EXTINGUISHED IN THE LIVING ORGANISM BY A STRONGER ONE, IF THE LATTER (WHILST DIFFERING IN KIND) IS VERY SIMILAR TO THE FORMER IN ITS MANIFESTATIONS. ( 14 )
Organon aphorism §27
The curative power of medicines, therefore, depends on their symptoms, similar to the disease but superior to it in strength (§12-26), so that each individual case of disease is most surely, radically, rapidly and permanently annihilated and removed only by a medicine capable of producing (in the human system) in the most similar and complete manner the totality of its symptoms, which at the same time are stronger than the disease.
Organon aphorism §28
As this natural law of cure manifests itself in every pure experiment and every true observation in the world, the fact is consequently established; it matters little what may be the scientific explanation of HOW IT TAKES PLACE; and I do not attach much importance to the attempts made to explain it. But the following view seems to commend itself as the most probable one, as it is founded on premises derived from experience.
Organon aphorism §29
As every disease (not entirely surgical) consists only in a special, morbid, dynamic alteration of our vital energy (of the principle of life) manifested in sensation and motion, so in every homeopathic cure this principle of life dynamically altered by natural disease is seized through the administration of a medicinal potency selected exactly according to symptom-similarity by a somewhat stronger, similar artificial disease-manifestation. By this the feeling of the natural (weaker) dynamic disease-manifestation ceases and disappears. This disease-manifestation no longer exists for the principle of life which is now occupied and governed merely by the stronger, artificial disease-manifestation. This artificial disease-manifestation has soon spent its force and leaves the patient free from disease, cured. The dynamis, thus freed, can now continue to carry life on in health. This most highly probable process rests upon the following propositions.
