John Hunter 1728-1795
British Vitalist physician
1. every disease is specific
2. every disease is of the whole person, so that 2 different “diseases” cannot co-exist in the same individual.
3. that medicines act by their “stimulating” power on the organism, not by producing evacuation or by neutralising toxins.

Empirical advice from Hunter to Edward Jenner: “Don’t think, try; be patient, be accurate.

Knowledge of medicines arises out of experience and practice, not out of theory.
