 At this point, the Prussian capital had no university of its own, and Fichte was forced to support himself by giving private tutorials and lectures on the Wissenschaftslehre and by a new flurry of literary production, increasingly aimed at a large, popular audience. The first of these “popular” writings was a brilliant presentation of some of the characteristic doctrines and conclusions of Fichte’s system, with a strong emphasis upon the moral and religious character of the same. This work, The Vocation of Man (1800), which is perhaps Fichte’s greatest literary achievements, was intended as an indirect response to Jacobi’s public repudiation of the Wissenschaftslehre. That same year also saw the publication of a typically bold foray into political economy, The Closed Commercial State, in which Fichte propounds a curious blend of socialist political ideas and autarkic economic principles. Defending his philosophy against misunderstanding remained, however, Fichte’s chief concern during this period, as is evidenced by the more direct response to Jacobi contained in his poignantly titled Sun-Clear Report to the Public at Large concerning the Actual Character of the latest Philosophy: An Attempt to Force the Reader to Understand (1801).
