||R. Jedaiah Bedersi's classic with a Judeo-German commentary and translation by several prominent Haskalah and Reform members including Moses Mendelssohn.
Sefer Behinat Olam ("The Book of the Examination of the World"), a lyrical, ethical monograph on the theme of the futility and vanity of this world, and the inestimably greater benefits of intellectual and religious pursuits. Behinat Olam, written in florid prose and rich in imagery, combines philosophic doctrine and religious fervor with a good measure of asceticism and pessimism.
Published originally in Mantua between 1476 and 1480, the work has been reprinted numerous times. It has been translated into English (Behinat Olam or An Investigation of... Organization of the World, London, 1806), Latin, French, German, Polish, and Yiddish, and numerous commentaries have been written on it.
