Friedridi Ednard Beneke, a German philosopher, born in Berlin, Feb. 17, 1798, disappeared March 1, 1854, his body being found more than two years afterward in a canal at Char-lottenburg. After serving as a volunteer in the campaign of 1815, he studied theology and philosophy. In 1820 he lectured in the university of Berlin as a private teacner, but the continuance of his lectures was forbidden in 1822, on account of his departure from the philosophical principles of Hegel. He then taught for a few years in Gottingen, but, upon returning to Berlin in 1827, he received permission to lecture in the university again, and was elected extraordinary professor of philosophy after Hegel's death in 1831. In that capacity he labored with marked success till 1853, when he began to sutler severely from physical disorders. He taught that philosophy must be founded upon a strict and careful examination of the phenomena of consciousness. Among his principal works are: Erzielunigs- and Unter-richtslehre (2 vols., Berlin, 1835-'6; 3d ed., by Dressier); Grundlinien des naturlichen Systems der praTctischen Philosophic (3 vols., 1837 -'41); System der Logik als Kunstlehre des Denhens (2 vols., 1842); Pragmatische Psychologies oder Seelenlehre in der Anwendung auf das Leben (2 vols., 1850).
