This article analyze the relationship between Schelling and Fichte in some philosophical and legal questions, previously developing mutual references and the problem of understanding in the philosophy (point 1). In Neue Deduktion des Naturrechts Schelling exposes several concepts that, in his own philosophy project, agrees with Fichte’s Wissenschaftslehre in fundamental points, particularly with Grundlage des Naturrechts (point 2). On basic coincidence, the most visible is the intersubjectivity and the conflict that appears with the other, which leads to the natural right problem. Schelling and Fichte share the skepticisms about original right and coaction right, but Fichte neutralizes war (that involves) all against all with State’s institution (point 3). Although, they seem to find different results, they agree in diagnostic about the individual will and the necessity to establish a common instance.
