CHRISTOPH WILHELM VON

SIGWART (1789-1844)  , German philosopher, was born at Remmingsheim in Wurttemberg, and died in Stuttgart . He became professor of philosophy at Tubingen, and wrote numerous books on the history of philosophy:—Uber den Zusammenhang des Spinozismus mit der Cartesianischen Philosophic (1816) ; Handbuch zu Vorlesungen fiber die Logik (1818, 3rd ed., 1835); Der Spinozismus (1839); and Geschichte der Philosophic (1844) . His son, CHRISTOPH VON SIGWART (1830-1894), after a course of philosophy and theology, became professor at Blaubeuren (18J9), and eventually at Tubingen, in 1865 . His principal work, Logik, published in 1873, takes an important place among recent contributions to logical theory . In the preface to the first edition, Sigwart explains that he makes no attempt to appreciate the logical theories of his predecessors; his intention was to construct a theory of logic, complete in itself . It re-presents the results of a long and careful study not only of German but also of English logicians . In 1895 an English translation by Miss H . Dendy was published in London . Chapter v. of the second volume is especially interesting to English thinkers as containing a profound examination of the Induction theories of Bacon, J . S . Mill and Hume . Among his other works are Spinozas neu entdeckter Traktat von Gott, dem Menschen and dessen Gliickscligkeit (1866); Kleine Salmi/ten (1881); Vorfragen der Ethik (1886) .

The Kleine Schriften contains valuable criticisms on

Paracelsus and Bruno .
