The works of the Italian criminologist Cesare Lombroso illustrates the fact that medicine, in the 19th century, is not only a therapeutic technique but, first and foremost, that it suggests a genuine « medical view of the world ». It is assumed that medicine would solve, once and for all, all the traditional philosophical problems. Lombroso’s references to medicine or measurement serve as evidence for materialistic and ultra-deterministic philosophical theses, and enable one to draw their political and social implications.
