Schelling’s aesthetic conception in the System of transcendental idealism can be seen as an attempt to a non-dogmatic, aesthetics restoration of such “strong structures” as God, truth and being, weakened definitely in Kant’s critical philosophy. The phenomenon of art attests that the Absolute is knowable and real. Following this, and precisely in this aesthetic restoration of the Absolute, the Romantic notion of Schelling’s transcendental philosophy is founded. I affirm that Romanticism delegates to Schelling the perfect instrument (organon) —the art—, for this restoration. Schelling is inspired in Romanticism to overcome the problems of subjective rationalism (Cartesian dualism and mechanicism, the one-dimensionality of the Fichtean self, and Kant’s separation of world to phenomenal and noumenal), and to make a step to positive philosophy or philosophy of life (Lebensphilosophie) in his later oeuvre.
