Five twelfth- and thirteenth-century polemicists from southern France and northern Spain are the first known Jewish polemicists from western Christendom, who identified major Christian challenges, as well as appropriate responses for fellow Jews under ever-increasing religious pressure. This analysis suggests that the Jewish polemicists ultimately attempted to offer their followers a significantly contrasting portrait of Christian and Jewish society: the former as powerful but irrational and morally debased; the latter as weak, but profoundly rational and morally elevated. 396 pages, hardcover from Cambridge University Press.
