 This is without a doubt the major philosophical work (and indeed the magnum opus) of  Crescas.[11]  This book was supposed to be the first part of a two-volume work that Crescas intended to write. The set was to be named Ner Elohim (Candle of God). The second book was to have been a work on Jewish law. The original aim of Crescas’s project was to counter the two major works of Maimonides by writing: I. A philosophical book against Maimonides’ Guide of the Perplexed. II. A legal book against his Mishneh Torah, in which Crescas would critique Maimonides’ legal method, and especially his lack of citations from earlier authorities. In fact, probably in part because of his communal role after 1391, he only had time to write the first book of the series, along with the general introduction to both volumes.
