Mental & Emotional Diseases

Organon Aphorism §217

In these diseases we must be very careful to make ourselves acquainted with the whole of the phenomena, both those belonging to the corporeal symptoms, and also, and indeed particularly, those appertaining to the accurate apprehension of the precise character of the chief symptom, of the peculiar and always predominating state of the mind and disposition, in order to discover, for the purpose of extinguishing the entire disease, among the remedies whose pure effects are known, a homoeopathic medicinal pathogenetic force – that is to say, a remedy which in its list of symptoms displays, with the greatest possible similarity, not only the corporeal morbid symptoms present in the case of disease before us, but also especially this mental and emotional state.
