§ 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.
§ 22 Fifth Edition
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 disease, 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, a 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 symptoms1) has a tendency to produce similar or opposite symptoms.
1 The other possible mode of employing medicines for diseases besides these two is the allopathic method, in which medicines are given, whose symptoms have no direct pathological relation to the morbid state, neither similar nor opposite, but quite heterogeneous to the symptoms of the disease, is, as shown above, in the introduction (Review of the therapeutics, allopathy and palliative treatment that have hitherto been practiced in the old school of medicine), merely instinctive vital force, which, when made ill by noxious agents, strives to save itself at whatever sacrifice by the production and continuance of morbid irritation in the organism – an imitation, consequently, of the crude vital force which was implanted in our organism in order to preserve our life in health, in the most beautiful harmony; but when deranged by disease, was so constituted as to admit of being again changed to health (homoeopathically) by the intelligent physician, but not to cure itself, for which the little power it possesses is so far from being a pattern to be copied, that all the changes and symptoms it produces in the (morbidly deranged) organism are just the disease itself. But this injudicious system of therapeutics of the old school of medicine can no more be passed by unnoticed that can history omit to record the thousands of years of opposition to which mankind has been subjected under the irrational, despotic Governments.

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 disease, 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, a 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 symptoms1) have the greatest tendency to produce similar or opposite symptoms.
Hahnemann's three major publications chart the development of homeopathy. In the Organon of Medicine, we see the fundamentals laid out. Materia Medica Pura records the exact symptoms of the remedy provings. In his book, The Chronic Diseases, Their Peculiar Nature and Their Homoeopathic Cure, he showed us how natural diseases become chronic in nature when suppressed by improper treatment.
