At the heart of the traditional historical method lie three fundamental presumptions. The traditional historical method regularly presumes that multiple versions of a text or tradition are equally authentic; it presumes that many ancient Jewish sources are the products of largely immanent forces of cloistered Jewish communities; and, barring any local grounds for suspicion, it presumes that most ancient Jewish texts faithfully reflect their sources and reliably recount events. unfurls the failings of this approach; it promotes the new historical method which circumvents the flawed traditional presumptions while plotting anew the limits of rational argumentation in historical inquiry. This crucial reappraisal is a must-read for students of Jewish and Roman history alike, and a fascinating case-study in how historians should approach their ancient sources.
