Le médecin à l'écoute des reves
In a number of his treaties (De Usu Partium, De Placitas Hippocratis et Platonis...), Galen returned to the role of phantasia: what kind of images are they? In which part of the body are they located? Should we consider them as symptoms of illness? We should reconstruct an intellectual approach that is based partly on experience, and partly on imagination which came into play to supply that which the physician could not observe. Melancholy too was credited with the power to stimulate the imagination. The medical discussions on the black bile, from Rufus of Ephesus to Johannes Actuarius, gave birth to a medical theory of enthusiasm.
