Coisa-em-si em Fichte: uma problematização

The concept of the thing-in-itself, both in Kant and in Fichte (in his writings between 1793 and 1797), has an ambiguous semantic field: sometimes it makes reference to the characterization of the realistic way of conceiving knowledge (theoretical and practical), others it represents a genuinely critical -transcendental determination. Fichte rejects the realistic sense of the concept, which plays for him an indispensable role, but in it’s critical sense. However, even in this last sense, there is a difference between Fichte’s and Kant’s understanding of the concept, once the author of the Foundation of the Entire Doctrine of Scientific Knowledge relates the concept of thing -in -itself to the investigation of feeling and, in particular, to the original feeling.
