This volume contains Jakob Karo's (b. 1912) inaugural dissertation at the University in Würzburg. The subject was "Critical investigations to R. Levi ben Gershom's (1288-1344) refutation of the Aristotelian time term.: a contribution of the Jewish Nature- philosophy of the Middle Ages." Levi ben Gershon was a Jewish philosopher, astronomer, and mathematician, called also Ralbag, from the initials of his Hebrew name, b. Languedoc. He wrote scientific works and commentaries on Averroës and the Torah. His Milchamoth Adonai [the wars of the Lord] is an elaborate treatise modeled after the Moreh Nevukhim of Maimonides. It is mainly a systematic criticism of the syncretism of Maimonides. His scientific views remained influential into the 19th cent. The title page lists Jakob Karo as being from Lodz.
