In his major philosophical opus, Kevod Elohim , written in Hebrew, Joseph ben Shem Tov investigates the summum bonum of man, which consists in the similarity to God's perfection called the "Glory of God" insofar as it can be realized by human nature. Opinions are divided, however, as to the nature of this greatest good. Some Jewish scholars claim that man's final purpose is in the observance of the 613 commandments of the Torah. According to the philosophers, the proofs of (...) Aristotle show irrefutably that man's highest happiness is in the grasping of cognition through reason. Other Jewish scholars assert that the mysteries of the Torah can be explored through philosophy and therefore the Torah and the sciences fulfill in principle the same purpose. This position, however, is objectionable to some believers on the ground that it denies the divine character of religion. On the other hand, to deny the proofs of Aristotle would be to coerce the findings of reason. If religion is the supreme good, it cannot contradict reason. Since the truth cannot be in conflict with the truth, Joseph's task is to compare, for the first time, the Nicomachean Ethics of Aristotle with the Torah to determine to what extent they agree or conflict. His method is to assemble all statements of Aristotle and his commentators on this subject and to submit them to critical analysis. Joseph's motivation is to justify the pursuit of Greek science, especially in view of his father Shem Tov ibn Shem Tov's virulent repudiation of philosophy, and to guide the perplexed of his generation who could not reconcile Greek wisdom with their faith. Joseph finds that the speculative eudemonia of Aristotle accords with the Torah. In an innovative interpretation of the Ethics, he reveals that Aristotle believed in individual providence over those who perfected their intellect and over those who practiced the ethical virtues. Joseph also identifies the study of Torah with the activity of speculation similar to the activity of the Separate Intellects. He finds no basis, however, in Aristotle's writings for the immortality of reason. Since the religious imperative grants immortality, it is infinitely greater than the eudemonia of reason. Thus, from a position of rapprochement between science and faith, Joseph considers them under the aspect of eternity and emerges with a complete denial of any ultimate resemblance between the two spheres.
