Method in Galen.
I have discussed the four methods of ancient philosophy namely demonstration, division, resolution, and composition. But first, I glance at logic, which "discovers the principles of medical treatment". Method in pathology discovers "the affected parts of the body" and nosology, "the symptoms of diseases and their causes". In therapeutics, method "discovers drugs appropriate to specific diseases". The leader in all things pertaining to method is Hippocrates.
