As a consequence of the specialization that thrives in current humanistic studies, it is not surprising that scholarship has tended to classify the literary creations of the past into fixed compartments. In the study of medieval Judaism, it is particularly common to follow the traditional division of disciplines into philosophy, Kabbalah, and rabbinism—a categorization that was indeed promoted by the medievals themselves. Following this way of thinking, the study of Rashi's biblical commentaries would be assigned to one class of scholars devoted to the study of rabbinic Judaism; Maimonides' Guide of the Perplexed to experts in Jewish philosophy; and the Zohar to yet a third group consisting of specialists in Jewish mysticism.
