Background: Friedrich Wilhelm Joseph Schelling (German: ['SelING]; 27 January 1775 - 20 August 1854), later (after 1812) von Schelling, was a German philosopher. Standard histories of philosophy make him the midpoint in the development of German idealism, situating him between Johann Gottlieb Fichte, his mentor in his early years, and Georg Wilhelm Friedrich Hegel, his former university roommate, early friend, and later rival. Interpreting Schelling's philosophy is regarded as difficult because of its apparently ever-changing nature. Schelling's thought in the large has been neglected, especially in the English-speaking world, as has been his later work on mythology and revelation, much of which remains untranslated.
Context: After two years tutoring, in October 1798, at the age of only 23, Schelling was called to University of Jena as an extraordinary (i.e., unpaid) professor of philosophy. His time at Jena (1798-1803) put Schelling at the center of the intellectual ferment of Romanticism. He was on close terms with Johann Wolfgang von Goethe, who appreciated the poetic quality of the Naturphilosophie, reading Von der Weltseele. As the prime minister of the Duchy of Saxe-Weimar, Goethe invited Schelling to Jena. On the other hand, Schelling was unsympathetic to the ethical idealism that animated the work of Friedrich Schiller, the other pillar of Weimar Classicism. Later, in Schelling's Vorlesung uber die Philosophie der Kunst (Lecture on the Philosophy of Art, 1802/03), Schiller's theory on the sublime was closely reviewed.  In Jena, Schelling was on good terms with Fichte at first, but their different conceptions, about nature in particular, led to increasing divergence in their thought. Fichte advised him to focus on philosophy in its original meaning, that is, transcendental philosophy: specifically, Fichte's own Wissenschaftlehre. But Schelling, who was becoming the acknowledged leader of the Romantic school, had begun to reject Fichte's thought as cold and abstract.  Schelling was especially close to August Wilhelm Schlegel and his wife, Caroline. A marriage between Schelling and Caroline's young daughter, Auguste Bohmer, was contemplated by both. Auguste died of dysentery in 1800, prompting many to blame Schelling, who had overseen her treatment. Robert Richards, however, argues in his book The Romantic Conception of Life that Schelling's interventions were not only appropriate but most likely irrelevant, as the doctors called to the scene assured everyone involved that Auguste's disease was inevitably fatal. Auguste's death drew Schelling and Caroline closer. Schlegel had moved to Berlin, and a divorce was arranged (with Goethe's help). Schelling's time at Jena came to an end, and on 2 June 1803 he and Caroline were married away from Jena. Their marriage ceremony was the last occasion Schelling met his school friend Holderlin, who was already mentally ill at that time.  In his Jena period, Schelling had a closer relationship with Hegel again. With Schelling's help, Hegel became a private lecturer (Privatdozent) at Jena University. Hegel wrote a book titled Differenz des Fichte'schen und Schelling'schen Systems der Philosophie (Difference between Fichte's and Schelling's Systems of Philosophy, 1801), and supported Schelling's position against his idealistic predecessors, Fichte and Karl Leonhard Reinhold. Beginning in January 1802, Hegel and Schelling published the Kritisches Journal der Philosophie (Critical Journal of Philosophy) as co-editors, publishing papers on the philosophy of nature, but Schelling was too busy to stay involved with the editing and the magazine was mainly Hegel's publication, espousing a thought different from Schelling's. The magazine ceased publication in the spring of 1803 when Schelling moved from Jena to Wurzburg.
