Halevi writes that as the Jews are the only depositaries of a written history of the development of the human race from the beginning of the world, the superiority of their traditions can not be denied. Halevi asserts that no comparison is possible between Jewish culture, which in his view is based upon religious truth, and Greek culture, which is based upon science only. He holds that the wisdom of Greek philosophers lacked that divine support with which the Israelite prophets were endowed. Had a trustworthy tradition that the world was created out of nothing been known to Aristotle, he would have supported it by at least as strong arguments as those advanced by him to prove the eternity of matter. Belief in the eternity of matter, however, is not absolutely contrary to Jewish religious ideas; for the Biblical narrative of the Creation refers only to the beginning of the human race, and does not preclude the possibility of preexistent matter.
