 Remarkably, there are clues that even the main representative of Arab-Islamic Sunnite theology, al-Ghazali (1058-1111), exerted an important ‘influence’ over some aspects of Medieval Jewish philosophy and thought. This fact has not yet been systematically studied and explained by scholars, but it cannot be easily neglected. Moreover, in the 14th century there was apparently a sort of “Jewish Ghazalism”, based upon al-Ghazali’s works (both philosophical and theological ones), so that many aspects of his thought as a typical Islamic thinker were curiously employed for defending some similar aspects of Jewish religious tradition.
