The Organon aphorisms, summarised

This is a working summary of the load-bearing aphorisms of Hahnemann's Organon — the numbered text in which every classical principle is grounded. The Organon runs to 291 aphorisms across six editions; aphorism numbers here follow the sixth edition in the O'Reilly translation.

The aim and the law (§1–§28)

The opening aphorisms set the physician's task and state the central law. §1 declares the physician's "sole vocation" is to restore the sick to health — the verb Hahnemann uses is the ordinary one for healing, not any absolute promise. §2 sets the ideal of treatment: rapid, gentle, and permanent restoration of health on clearly comprehensible principles. §3 names the four things the physician must grasp — what is disease, what is curative in each medicine, how to match medicine to case, and how to prepare and dose it. §5–§18 develop the doctrine that the totality of perceptible symptoms is the sole knowable face of disease, so the symptom-image is what treatment must address. §19–§28 establish the law of similars: a medicine that can produce a set of symptoms in a healthy prover resolves a similar set in the sick — similia similibus curentur, "let likes be treated by likes". This is the axiom the whole system rests on.

The nature of disease and cure (§9–§71)

These aphorisms carry Hahnemann's account of how disease and cure work. §9–§12 introduce the vital force (the dynamis): health is the harmonious working of this self-maintaining principle, disease is its dynamic mistunement, and the remedy acts on this reactive plane rather than on tissue directly. §22–§25 argue from the similar principle that the right medicine is the one whose proving picture most resembles the case. §63–§69 set out the doctrine of primary action and the organism's secondary counter-action — the account of why a small similar dose provokes a curative response.

Case-taking and the hierarchy (§83–§104, §153)

These are the most directly usable aphorisms in clinical work. §83–§99 are the case-taking rules: the physician records the patient's complaints in the patient's own words, observes without leading, and writes down the complete picture — onset, modalities, concomitants — before interpreting it. §104 stresses that the carefully recorded totality is what makes the case treatable and reviewable later. §153 is the hinge of remedy selection: in matching remedy to case, "the more striking, exceptional, unusual, and peculiar (characteristic) signs and symptoms" carry decisive weight, while common, diagnostic symptoms count for little. This is the source of the hierarchy of symptoms and of the strange-rare-peculiar emphasis that runs through Kent's principles and all later case-taking practice.

Remedy, dose, and repetition (§246–§285)

These aphorisms govern how the remedy is given. §246–§248 are the sixth-edition dosing rules and the largest practical change from the fifth edition: the well-chosen remedy is repeated in ascending, freshly succussed doses as long as it continues to help and the symptom-state keeps changing, rather than given once and left for weeks. This LM-potency, graduated-repetition method differs from the single-dose high-potency practice Kent built on the fifth edition, which is why citing a dosing rule from the Organon requires naming the edition. §272–§274 require the single remedy: one medicine at a time, never a mixture, because only a single proven substance has a known symptom-image to match. §275–§283 cover the size and adjustment of the dose; §285 and the surrounding aphorisms set the minimum-dose principle — the smallest quantity that provokes a curative reaction.

The chronic frame (§72–§81)

§72–§81 distinguish acute from chronic disease and introduce the chronic-miasm doctrine Hahnemann expanded in The Chronic Diseases (1828). Well-chosen remedies relieve chronic cases only temporarily because the visible complaint is the surface of a deeper persisting miasm; the chronic case must be prescribed on the whole longitudinal history, miasm included.

A practitioner working a case executes most of this sequence — record the §83–§104 totality, weight the §153 characteristic symptoms, choose the §272 single remedy, plan the §246 dosing. The mechanical parts sit naturally inside repertory software: a case record for the consultation notes, rubrics graded 0–4 so the characteristic symptoms carry more of the analysis in line with §153, and a materia medica lookup to confirm the leading remedy against the classic sources before the single remedy is fixed.

The §83–§104, §153, §246–§248, and §272–§274 blocks are the ones a clinician returns to most often. For the full argument, read the Organon in a careful sixth-edition translation.
