Abstract

Diderot’s reading of Le Camus’ Médecine de l’Esprit may occupy a prominent position in his research for the Eléments de physiologie, but his thoughts on the matter are not restricted to a criticism of this work, which appeared in 1753. In his edition of the Eléments de physiologie, Jean Mayer showed that Diderot had instigated an ongoing debate with other physicians who were also concerned with the issue of a ‘medicine of the mind’: Bonnet, Marat, Le Cat, not to mention Bordeu and Haller. In view of the poignancy of Le Camus’ questions, however, his Médecine de l’Esprit may be taken as the hidden clue to a series of questions ranging from the perfectibility of the human mind to the curing of insanity, and thus spanning the limits of the human spectrum—from idiot to genius. The open possibility of creating a medicine of the mind is in fact a restatement of the problem of the respective weight of ‘organization’ and education, understood here in the broadest sense. This problem forms an essential part of the Réfutation d’Helvétius. Furthermore, this possibility leads one to inquire into the physician’s ability to intervene in the organization itself. Thus the question of the ‘innate’ and the ‘acquired’ shifts in some sense, so that it is now located within the problem of organization, which now means more than just the material organ of thought. Ultimately, it is this expression, ‘organization’, which I wish to elucidate further.
