This first full-length study of the Arabic reception of Plato's Timaeus considers the role of Galen of Pergamum (129-c. 216 CE) in shaping medieval perceptions of the text as transgressing disciplinary norms. It argues that Galen appealed to the entangled cosmological scheme of the dialogue, where different relations connect the body, soul, and cosmos, to expand the boundaries of medicine in his pursuit for epistemic authority - the right to define and explain natural reality. Aileen Das situates Galen's work on disciplinary boundaries in the context of medicine's ancient rivalry with philosophy, whose professionals were long seen as superior knowers of the cosmos vis-a-vis doctors. Her case studies show how Galen and four of the most important Christian, Muslim, and Jewish thinkers in the Arabic Middle Ages creatively interpreted key doctrines from the Timaeus to reimagine medicine and philosophy as well as their own intellectual identities.

The present volume offers an edition, updated English translation of, introduction to, and seven multi-authored contributions on Galen's small tract That the Best Doctor is also a Philosopher. The volume seeks to put Galen's text into conversation with recent interrogations of medicine's self-sufficiency - or disciplinary autonomy - in the Medical Humanities. As the title of the ancient work conveys and the essays in this volume unpack, Galen argues for a reenvisioning of medicine by making philosophy constitutive of his profession on the grounds that the latter's methods of reasoning, explanations of the natural world, and ethical directives enable the doctor to understand and treat the body in disease. In so doing, Galen expands medical knowledge at the expanse of instrumentalizing the philosophical.
