Book excerpt: The first full-length treatment of Ibn Gabirol's philosophy in English, this study completely reinvents the medieval author of the Fountain of Life or Fons Vitae (known to many in the history of philosophy by his Latinized name, Avicebron). Developing Ibn Gabirol's vision in terms of a "Theology of Desire," the book rescues the voice of the eleventh-century Jewish poet-philosopher from centuries of misreadings as it sets out to examine the role of love, desire, and ethical self-transformation in medieval Jewish Neoplatonism.
