Stahl, Leibniz, Hoffmann & la respiration

Abstract : At the beginning of eighteenth century, Leibniz and Hoffmann criticize Stahl's medical theory : they differenciate between unsound and true reasonings. Namely, they validate Stahl's definition of breath but extracting it from its animist basis and placing it in an epistemology obeying to the principle of sufficient reason and to the mechanical model. The stahlian discovery consists in understanding breath as a calorific ventilation against the antic conception ; the iatromechanists recognize its accuracy, but they try then to transpose it inside a mechanical model of ventilation. Using it in a different epistemological context implies that they analyze the idea of discovery "true" in its contents, but "wrong" in its hypothesis. It impels to examine the epistemology of medical knowledge, as science and therapeutics, and in its links with the other scientific theories. Thus, if Leibniz as philosopher and Hoffmann as doctor consider Stahl's animism so important, it's because its discoveries are regarding the fundamental principles of medicine.
