  Discussing the relationship between the prophet and the wise man, Kaspi agrees with the Muslim thinker al-Batalyusi that a person with a prophetic soul is superior in level and essence to the wise man who has a philosophical soul. Nevertheless, prophecy is not a super-rational phenomenon. A prophet’s knowledge of the future is based on deductive inference, since he or she is well acquainted with the world and with all details of natural causality.
