BILFINGER or BULFFINGER, GEORG (1693-175o), German philosopher, mathematician and statesman, was born on Jan. 23, 1693, at Kanstatt, Wurttemberg. He studied philosophy under Wolff, became professor of phil osophy (17 21) and then of mathematics (17 24) at Halle. His Dilucidationes philosophicae de deo, anima humana, mundo (Tu bingen, 17 25) is a clear presentation of Wolff's philosophy. On Wolff's recommendation he was invited by Peter the Great to lecture at St. Petersburg, and he remained there from 1725 to 1731. In the latter year he returned to Germany, became pro fessor of theology at Tubingen, and a member of Duke Charles Alexander's council. On the duke's death he became a member of the Regency Council, and helped to reorganize education and agriculture in the State. He died at Stuttgart on Feb. 18, 175o.
Beside the Dilucidationes, he wrote :—De Harmonia animi et corporis hurnani commentatio (Frankfort and Leipzig, 1725 ;) De origin et permissione mall (1724), an account of the Leibnitzian theodicy.
