The Guide for the Perplexed
Following on from his father, Messer Leon's son also became a noted rabbi, physician and author, and defender of the value of the secular disciplines of the Renaissance to Jewish philosophy culture and study. David became best known for his "Ein ha-Kore" ("Eye of the Reader"), a sympathetic commentary on Maimonides' "The Guide for the Perplexed"; and posthumously for his "Tehillah le-Dawid" ("Glory to David"), an encyclopedic summary of Jewish philosophy, edited by his grandson Aaron ben Judah (Constantinople, 1577).
