Torah in the Observatory: Gersonides, Maimonides, Song of Songs Menachem Kellner Gersonides (1288-1344) was, in my view, the most original philosopher in medieval Judaism. However, he has not been studied to the same extent as other Judaic luminaries, and only his Commentary on the Song of Songs has been (magnificently!) translated into English (1998), after an excellent Hebrew edition of the Introduction was published (1989), both the work of Menachem Kellner. This new volume by Menachem Kellner explores some of the most important questions raised by Gersonides: Providence, Mosaic Prophecy, Miracles, the Messiah and Resurrection, Astronomy and Metaphysics, Politics and Perfection… It is not by chance that Menachem Kellner has devoted so much to the study of Gersonides. Like Gersonides, Kellner has firmly in hand the knowledge of the Bible and of the traditional literature of Judaism, he is well trained in philosophy and science, and his broad interests make him the best and most penetrating champion of a great philosopher and an outstanding student of human thought.
