Prantl, Karl Von
PRANTL, KARL VON (1820-1888), German philosopher, was born at Landsberg on the Lech on the 28th of January 1820, and died on the 14th of September 1888 at Oberstdorf. In 1843 he became doctor of philosophy at Munich Observatory, where he was made professor in 1859. He was also a member of the Academies of Berlin and Munich. Strongly in agreement with the Hegelian tradition, he defended and amplified it in Die gegemviirtige Aufgabe der Philosophic (1852) and Verslehen una Beurteilen (1877). In these works he emphasized the identity of the subjective and the objective for consciousness, and the fact that the perception of this unity is peculiar to man. He is more important, however, as a commentator and scholar, and made valuable contributions to the study of Aristotle. He published Aristoteles ilber die Farben (1849), Aristoteles' acht Bilcher der Physik (1857), and numerous minor articles on smaller points, such as the authenticity of the thirty-eight books of the Problems. The work by which he is best known is the Geschichte der Logik im Abendland (Leipzig, 1855-1870). Chr. Sigwart, in the preface to the first edition of his Logic, makes " special mention " of the assistance he obtained from this book.
