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 Würzburg.
