"Therefore in medicine we ought to know the causes of sickness and health"
About this Quote
The phrase “ought to know” is quietly radical. It’s normative, almost moral. A physician who can stop a fever by luck or habit is not yet doing medicine in the full sense; the profession earns legitimacy by pursuing causality. That subtext elevates the doctor from technician to investigator and makes medicine a branch of disciplined reasoning, aligned with his broader project in The Canon of Medicine: systematize observation, logic, and existing learning into a coherent framework.
“Causes of sickness and health” also widens the aperture. He’s not satisfied with disease as an isolated event. Health becomes equally explicable, something with determinants worth studying - diet, environment, temperament, regimen. The move is strategic: if you understand health’s causes, prevention becomes as intellectually serious as cure, and the physician’s authority extends into everyday life.
Context sharpens the intent. Avicenna stands at a crossroads of Greek medical theory (especially Galen), Islamic scholarship, and his own metaphysical commitments. Cause, for him, isn’t only correlation; it’s structure. The quote reads like a manifesto for medicine as rational culture, not just emergency service.
