Period of intense productivity.
In 1798 Schelling was called to a professorship at the University of Jena, the academic centre of Germany at the time, where many of the foremost intellects of the time were gathered. During this period Schelling was extremely productive, publishing a rapid succession of works on the philosophy of nature. It was Schelling’s desire, as attested by his famous work System des transzendentalen Idealismus (1800; “System of Transcendental Idealism”), to unite his concept of nature with Fichte’s philosophy, which took the ego as the point of departure. Schelling saw that art mediates between the natural and physical spheres insofar as, in artistic creation, the natural (or unconscious) and the spiritual (or conscious) productions are united. Naturalness and spirituality are explained as emerging from an original state of indifference, in which they were submerged in the yet-undeveloped Absolute, and as rising through a succession of steps of ever-higher order. Fichte did not acknowledge this concept, however, and the two writers attacked each other most sharply in an intensive correspondence.
The time spent in Jena was important for Schelling also in a personal respect: there he became acquainted with Caroline Schlegel, among the most gifted women in German Romanticism, and married her in 1803. The unpleasant intrigues that accompanied this marriage and the dispute with Fichte caused Schelling to leave Jena, and he accepted an appointment at the University of Würzburg.
At first, Schelling lectured there on the philosophy of identity, conceived in his last years in Jena, in which he tried to show that, in all beings, the Absolute expresses itself directly as the unity of the subjective and the objective. It was just on this point that G.W.F. Hegel initiated his criticism of Schelling. Hegel had at first taken Schelling’s side in the disagreement between Schelling and Fichte, and complete unanimity seemed to exist between them in 1802 when they coedited the Kritisches Journal der Philosophie (“Critical Journal of Philosophy”). In the following years, however, Hegel’s philosophical thought began to move significantly away from Schelling’s, and his Phänomenologie des Geistes (1807; The Phenomenology of Mind) contained strong charges against Schelling’s system. To Schelling’s definition of the Absolute as an indiscriminate unity of the subjective and the objective, Hegel replied that such an Absolute is comparable to the night, “in which all cows are black.” Besides, Schelling had never explicitly shown how one could ascend to the Absolute; he had begun with this Absolute as though it were “shot out of a pistol.”
This criticism struck Schelling a heavy blow. The friendship with Hegel that had existed since their time together at the seminary in Tübingen broke up. Schelling, who had been regarded as the leading philosopher of the time until the publication of Hegel’s Phänomenologie, was pushed into the background.
This situation caused Schelling to retreat from public life. From 1806 to 1841 he lived in Munich, where, in 1806, he was appointed as general secretary of the Academy of Plastic Arts. He lectured from 1820 to 1827 in Erlangen. Caroline’s death on Sept. 7, 1809, led him to write a philosophical work on immortality. In 1812 Schelling married Pauline Gotter, a friend of Caroline. The marriage was harmonious, but the great passion that Schelling had felt for Caroline was unrepeatable.
During the years in Munich, Schelling tried to consolidate his philosophical work in a new way, producing a revision that was instigated by Hegel’s criticism. Schelling questioned all idealistic speculations built on the assumption that the world presents itself as a rational cosmos. Were there not also irrational things, he asked, and was not evil the predominant power in the world? In his Philosophische Untersuchungen über das Wesener menschlichen Freiheit (1809; Of Human Freedom), Schelling declared that the freedom of man is a real freedom only if it is freedom for good and evil. The possibility of this freedom is founded on two principles that are active in every living thing: one, a dark primal foundation that manifests itself in carnal desire and impulse; the other, a clearheaded sensibleness that governs as a formative power. Man, however, has placed the dark stratum of impulse, which was meant only to serve the intellect as a source of power, above the intellect and has thus subordinated the intellect to the impulses, which now rule over him. This reversal of the right order is the occurrence known in the Bible as the Fall from grace, through which evil came into the world. But this perversion of man is revoked by God, who becomes man in Christ and thus reestablishes the original order.
