The geographical theory of property still remains unachieved despite some authors' requests to that effect. Though not pretending to complete the elaboration of such a theory, this article, starting from a critique of Ratzel's political geography, aims to set a track in that way. The critique first shows that his geography gives a definition of property and state based on a dogmatic conception of individuals. Ratzel's proposition presents the individual as being an absolute entity around which rises, in order to satisfy needs, the political structure. As the opposite view of this individualistic apriority, the article analyses the discursive dimension of property. It turns out that property, since it is based on a dogmatic mode, imposes a privation on which rests the institution of the specifically distinguished and human subject.
