This perfection of man, or which is the same thing, the perfection of the human soul, is brought about through perfection in morals and in theoretical speculation, as will appear more clearly when we discuss the nature of the human intellect and its immortality. Hence the purpose of the Bible is to lead man to perfect himself in these two elements—morals and science. For this reason the Law consists of three parts. The first is the legal portion of the Law containing the 613 commandments, mandatory and prohibitive, concerning belief and practice. This is preparatory to the second and third divisions of the Pentateuch, which deal respectively with social and ethical conduct, and the science of existence. As far as ethics is concerned it was not practicable to lay down definite commandments and prohibitions because it is so extremely difi&cult to reach perfection in this aspect of life. Thus if the Torah gave definite prescriptions for exercising and controlling our anger, our joy, our courage, and so on, the results would be very discouraging, for the majority of men would be constantly disobeying them. And this would lead to the neglect of the other commandments likewise. Hence the principles of social and ethical conduct are inculcated indirectly by means of narratives exemplifying certain types of character in action and the consequences flowing from their conduct. The third division, as was said before, contains certain teachings of a metaphysical character respecting the nature of existence. This is the most important of all, and hence forms the beginning of the Pentateuch. The account of creation is a study in the principles of philosophical physics.336
As to the relations of reason and belief or authority, Levi ben Gerson shares in the optimism of the Maimonidean school and the philosophic middle age generally, that there is no opposition between them. The priority should be given to reason where its demands are unequivocal, for the meaning of the Scriptures is not always clear and is subject to interpretation.337 On the other hand, after having devoted an entire book of his "Milhamot" to a minute investigation of the nature of the human intellect and the conditions of its immortality, he disarms in advance all possible criticism of his position from the religious point of view by saying that he is ready to abandon his doctrine if it is shown that it is in disagreement with religious dogma. He developed his views, he tells us, because he believes that they are
