A translation of the Fons vitae of Solomon ibn Gabirol (born 1021/1022), who was the first Jewish philosopher in Spain. In the Fons vitae, Gabirol argues that there is a sensible and an intelligible world. These doctrines profoundly influenced medieval Christian thinkers. Because of the Fons vitae, Gabirol is today widely recognized as one of the greatest Jewish Neoplatonists.
