A classification and definition of the analytical marks in the ideas of the Reason

Abstract

Noumena are, in principle, limits concepts. In the Kantian corpus we find multiple of them, whose role is decisive in the treatment of previous metaphysics as well as in the proposal of alternative metaphysics. Kant, however, does not stop to explain to us where these concepts come from and where they would go. The present research suggests that from the concept of mark (Merkmal) presented in the KrV and developed in the Jäsche Logik, we can understand these noumena as the analytical, sufficient, essential and primitive notes of the ideas of reason, both theoretical and practical.
