The Name of God in Jewish Thought examines the texts of Judaism pertaining to the Name of God, offering a philosophical analysis of these as a means of understanding the metaphysical role of the name generally, in terms of its relationship with identity. The book begins with the formation of rabbinic Judaism in Late Antiquity, travelling through the development of the motif into the Medieval Kabbalah, where the Name reaches its grandest and most systematic statement - and the one which has most helped to form the ideas of Jewish philosophers in the 20th and 21st Century. This investigation will highlight certain metaphysical ideas which have developed within Judaism from the Biblical sources, and which present a direct challenge to the paradigms of western philosophy. Thus a grander subtext is a criticism of the Greek metaphysics of being which the west has inherited, and which Jewish philosophers often subject to challenges of varying subtlety; it is these philosophers who often place a peculiar emphasis on the personal name, and this emphasis depends on the historical influence of the Jewish metaphysical tradition of the Name of God.
