 The fourth treatise of the book presents a typology of four different groups of people, who, according to Polqar, constitute the greatest enemies of Judaism and, as a consequence, of philosophy. The first group consists of those who reject science while claiming to be true believers. The second includes the Kabbalists, who claim to have access to esoteric knowledge reaching back to the prophets, and who reject the philosopher’s methods (such as syllogism) as legitimate tools for evaluating knowledge claims. The third group comprises those who accuse philosophers of holding radical naturalistic views. According to this group, philosophers assert that everything is governed by nature and that even God cannot change its course. For these traditionalists, then, philosophers have turned nature into God’s rival, not His intermediary. The fourth group includes people who believe in magic, witchcraft, and the like.
