Schelling studied the Church fathers and ancient Greek philosophers. His interest gradually shifted from Lutheran theology to philosophy. In 1792 he graduated with his master's thesis, titled "Antiquissimi de prima malorum humanorum origine philosophematis Genes. III. explicandi tentamen criticum et philosophicum", and in 1795 he finished his doctoral thesis, titled "De Marcione Paulinarum epistolarum emendatore" ("On Marcion as emendator of the Pauline letters") under Gottlob Christian Storr. Meanwhile, he had begun to study Kant and Fichte, who influenced him greatly. Representative for Schelling´s early periode is also a discourse between him and the philosophical writer , who was Fichte´s housemate at that time, in letters and in Fichte´s Journal (1796/97) on "interaction", "the pragmatic" and Leibniz.
