'I have known Professor Novak for several decades. I have not ceased to be astonished by his versatility, by his thorough familiarity with the full range of classical Jewish literature, and by his talent for finding matching analogies in general world literature. He combines both the traditional scholar's facility in conceptual analysis with the critical scholar's insistence upon exactitude and accuracy. Only Professor Novak with his profound knowledge of Judaica and his acumen in philosophy could have written such a sensible and reliable book on Natural Law in Judaism which embraces also law, philosophy and ethics. The manner in which he integrates these subjects is a scholarly feat, the intellect at its best.' David Weiss Halivni, Columbia University
