 Bauer’s bicentennary in September 2009 was the occasion for a three-day international conference, held at the Friedrich-Schiller-Universität, Jena, and in Bauer’s nearby birthplace of Eisenberg, to examine his problematic legacy for philosophy, theology, and social thought. The conference sought to retrieve the complex theoretical debates underlying the collapse of the Hegelian system. Bauer’s reformulation and radicalisation of Hegel were contrasted with the criticisms of Ludwig Feuerbach, Max Stirner, and Karl Marx; and the specific character of his Vormärz radicalism was underlined, whether in his republicanism or in his theological insights and critique. Disputed issues involved the content, continuity, and political bearing of Bauer’s pre-1848 works, his relations with his contemporaries in the Hegelian School, the question of his anti-Semitism, and his attitudes toward imperialism and history after 1848. Also highlighted was the later Bauer’s reception by twentieth-century conservatives such as Carl Schmitt. The Proceedings of the conference were published in 2010 (Kodalle and Reitz, eds., 2010)
