Abstract

Albert the Great’s Aristotelian paraphrases (De animalibus, Parva Naturalia) are famous for their extensive use of medical doctrines. Their use is not unprecedented in other Albertinian works, though. This article tries to show how Albert’s early theological works (De homine, Commentarium super libros Sententiarum) provide crucial evidence to understand the rationale behind Albert’s integration of medico-philosophical doctrines into his mature works of natural philosophy. In the first place, the early works assert that medicine – at least, its theoretical part – treats a natural body subject to a natural process (healing), a view that leads Albert in his mature works to consider (this part of) medicine as a part of natural philosophy. Secondarily, the article moves on to show how Albert’s selective attitude towards medical doctrines and his position on the Galenic-Aristotelian quarrels about generation and origin of veins date back to his De homine and are strongly – although not entirely – dependent on Avicennian zoology and medicine. Unlike Avicenna, Albert would reshape in his mature works notions of Galenic and Avicennian medicine (spirit, radical, moisture) and zoology (formative power) into an original paradigm of ‘universal physiology’, meant to investigate the world of plants and minerals not only according to their parts and functions but also according to their species.
