Organon §5: the fundamental cause, and why history-taking is not optional

The aphorism

In §5 of the Organon, Hahnemann directs the physician to take account of the exciting cause of an acute disease and — in chronic cases — of the patient''s history, mode of living, occupation, habits and social circumstances.

It reads like preamble. It is not. It is a working instruction, and ignoring it explains a specific and very common failure.

The failure it prevents

You take the case well. You repertorise carefully. The remedy is genuinely well selected and the patient improves — then relapses. You repeat; it works less well. You change potency. Then you change remedy, and now you are chasing.

Frequently nothing was wrong with the prescription. The maintaining cause was never removed. A patient sleeping four hours a night because of shift work, or in continuous conflict at home, or carrying a stimulant load they did not mention, is being pushed back into the state faster than any remedy can shift it.

Exciting versus maintaining

Worth separating, because they call for different responses:

• The exciting cause started it — a grief, a fright, a soaking, a suppressed discharge. This is often your best single rubric. "Ailments from…" rubrics are among the most valuable in the repertory precisely because they individualise so sharply.
• The maintaining cause keeps it going — occupation, posture, hours, diet, an ongoing relationship. This one you must address directly, because no potency removes it.

What this means for your consultation

Ask routinely, and write the answers down:

1. "What was happening in your life when this started?" — not "what triggered it", which invites a medical answer
2. "What does an ordinary day look like for you?" — hours, meals, work, sleep
3. "Is there anything that has not settled since?"

The third question surfaces griefs and shocks patients do not consider medically relevant and therefore never volunteer.

The uncomfortable part

Sometimes the honest answer is that a prescription is not the intervention that will help this patient most. Saying so is not a failure of the method — Hahnemann says as much himself, and a physician who cannot say it is not practising §5.
