The Unpublished Medicina contracta of Arnold Geulincx

In this paper I provide a commentary on and edition of the unpublished and apparently incomplete Medicina contracta of the Flemish philosopher Arnold Geulincx (1624–1669). This short treatise, dating to c. 1668–1669, was not included in the edition of Geulincx’s works edited by J. P. N. Land, on the ground of its apparent unoriginality. However, it reveals the attempt, by Geulincx, to develop a medicine based on a new account of disease (intended in Cartesian-Platonic terms of the impossibility of the mind using the body through animal spirits), and integrating avant- garde solutions typical of iatrochemistry (in particular those of Franciscus Sylvius) and iatromechanics. The text, which I also consider in the light of Geulincx’s disputations in physiology, is moreover revelatory of his ongoing efforts in understanding the nature of respiration and its related diseases and conditions, such as apoplexy, and of his progressive, albeit not uncritical acceptance of Cartesianism.
