Abstract

The contribution analyses the third part of the "Allgemeine Naturgeschichte", written by Kant in 1755, and focuses in particular on the ontological nexus that relate the activity of the soul to the material quality and to the morphology of the organic body. In the course of the analysis, the presence of two argumentative logics of Kant’s discourse will be highlighted. For the first one, the body is a limitation of the spirit, which would fully develop its cognitive faculties if it were not connected to any matter. For the second one, on the contrary, the connection with the body becomes a necessary condition for the spirit to be given the faculty to exercise its own power of thought.
