Halbertal then turns to Maimonides's legal and philosophical work, analyzing his three great books— , the , and the . He discusses Maimonides's battle against all attempts to personify God, his conviction that God's presence in the world is mediated through the natural order rather than through miracles, and his locating of philosophy and science at the summit of the religious life of Torah.
