Organon of Medicine in the Second Year — disease, case taking and the record
What HomUG-OM-II covers: aphorisms 28–104, the classification of disease, case taking, record keeping, causation, individualisation and suppression.

The first-year Organon course gave a student the history of homoeopathy, the tools of logic, and the opening aphorisms. The second-year course — HomUG-OM-II in the NCH curriculum — takes up the text where the first left its gap, and moves from the principles of the system towards the physician’s working method. By the end of it, a student has read the Organon’s account of disease, its classification, and its instructions for taking and recording a case.
The CBDC course content has twelve chapters. Several are anchored in named ranges of aphorisms; the rest are philosophical themes that grow out of them.
**The text, in order of the argument.** The course reads four blocks of aphorisms and one single aphorism:
– Aphorisms 28–33: natural disease and artificial disease.
– Aphorisms 34–51: the correctness of the homoeopathic therapeutic law of nature.
– Aphorisms 52–70: the various systems of medicine.
– Aphorisms 71–82: the classification of diseases — the Hahnemannian classification — with an introduction to miasm.
– Aphorisms 83–103: case taking.
– Aphorism 104: record keeping.
Read alongside the first-year ranges (1–27 and 105–145), this means that by the end of the second year a student has met the Organon continuously from its first aphorism to its hundred-and-forty-fifth. The second year fills the middle.
**Homoeopathic philosophy.** One chapter gathers the concepts that turn those aphorisms into method: symptomatology, case taking, case processing, the analysis of symptoms, the evaluation of symptoms, the totality of symptoms, and susceptibility. These are the working words of a homoeopathic physician, and the second year is where they are first studied as a connected set rather than as separate definitions.
**The themes that follow from the text.** Five further chapters widen the view.
– Causation: understanding how disease evolves, taking into account predisposing, fundamental, exciting and maintaining causes.
– Individuality and individualisation, and the process by which a physician individualises.
– Anamnesis and the evolution of disease — the patient’s history read as a story that develops over time.
– Disease, its progress, and the relation of complex disease with miasm.
– An introduction to the concept of suppression.
Each of these is a doorway into the later years. Miasm is introduced here and developed further on; suppression is introduced and not yet exhausted; individualisation is named as a process, which is a way of saying it is a skill to be practised, not a fact to be memorised.
**Why this year matters.** If the first-year Organon course explains what homoeopathy believes, the second-year course explains what a homoeopath does first: take the case. The four blocks on disease and its classification tell the student what they are looking at; the case-taking aphorisms tell them how to look; the record-keeping aphorism tells them to write it down. The philosophy chapter gives them the language to analyse and evaluate what they have recorded.
The subject does not stand alone in the year. The Repertory course of the second year demonstrates case taking in simple, acute and chronic cases, with explicit reference to the Organon’s instructions — so the two subjects teach the same act from two sides. The Materia Medica course asks the student to read medicines with the clinical vocabulary of the year. And the clinical subjects that begin in this year — Practice of Medicine, Surgery, Gynaecology and Obstetrics — each speak of miasm, susceptibility or the Organon in their own syllabi. The Organon is the common reference they all point to.
As this room fills, a student will find pieces written to this syllabus: guided readings of each aphorism block, explainers on the philosophy chapter’s terms — what separates analysis from evaluation, what the totality of symptoms means in practice, how susceptibility is understood — and orientations to the concepts introduced here and developed later, such as miasm and suppression. Everything here carries the second-year tag and the Organon category, so it also stands on the Organon topic in Homoeopathy Knowledge. The room grows as the community writes, and the twelve chapters above are its plan.
