pearance one after the other, yet without the peculiar chilly, shivering rigor.
Briefly, even those symptoms which are of regular occurrence and especially characteristic-as the stupidity of mind, the kind of rigidity in all the limbs, but above all the numb, disagreeable sensation which seems to have its seat in the periosteum, over every
bone in the body—all these made their appearance. This paroxysm lasted two or three hours each time and recurred if I repeated.this dose, not otherwise; I discontinued it, and was in good health."
Imagine the astounding revelation that struck Hahnemann as a result of his experiment! The standard medical assumption had always been that if the body produces a symptom, a medicine must be given to relieve that symptom. This was so deeply ingrained that it had almost become an automatic reflex in the mind of doctor and patient. But here, in his own personal experience, Hahnemann found that a drug which was known to be curative in malaria actually produces those very symptoms when given to a healthy person.
Many would simply have ignored such an observation as a mere exception. Hahnemann, however, was a true empirical scientist. To him, the observation itself was what counted—regardless of whether it fitted neatly into current dogmas or not. He accepted the observation and went on to make further experiments which further proved this ‘chance’ observation as a fact of Nature: A substance which produces symptoms in a healthy person cures those symptoms in a sick person.
Hahnemann and his colleagues recognized in these symptom pictures the identical symptomatologies of many people seeking cures. These medicines were then tried on patients who manifested similar symptoms, and the amazing discovery was made that the drugs actually cured so-called "incurable" diseases when prescribed according to this principle. According to the law he had discovered, Hahnemann saw that every drug must necessarily cure the set of symptoms it produces in a healthy human organism.
The process by which Hahnemann and his colleagues experimentally produced the symptoms of a substance upon their healthy organisms he called "proving". Orthodox medicine (which homeopaths term "allopathic", from allo, meaning "other") also has its process of proving drugs, but with the very important difference that it experiments upon animals.
Animals do not possess the power of speech. They cannot report the subtleties of alterations in mood or the different types of pain which can be described by human experimental subjects. In addition, the physiology of animals is considerably different from that of the human being. Hahnemann perceived clearly that any therapeutic system based upon animal experimentation must be done within the same realms of physiology and awareness as the medicines will be called upon to act therapeutically. This principle is merely common sense, yet it was absolutely revolutionary in Hahnemann’s time.
Hahnemann’s rationale for the homeopathic principle, known today as the Law of Similars, is explained in Aphorism 19 of the Organon:
