Jonathan Klawans' 'Josephus and the Theologies of Ancient Judaism' cuts against the grain of rabbinic studies to establish the value of Flavius Josephus' descriptions of the religious ideas of various Jewish sects for reconstructing the world of ideas (the theologies) at play in early Judaism. It is intended as a response to the prevalent approach to the study of early Judaism, which focuses on legal or halakhic issues rather than matters of religious belief.
