 Part two contains the pre-Cartesian view of truth and wisdom as a result of a universal revelation to the Hebrews that was transmitted through the Greeks, Romans, and Islam to medieval Christianity. This view would be influential in Philosophy up to the age of Francis Bacon and Descartes. Roger Bacon links it to a doctrine of illumination taken from Augustine, Avicenna, and the commentary on the Pseudo-Ptolemy: Centiloquium. He contrasts the tradition of the great philosophers such as Plato and Aristotle with the mythical traditions from ancient times.
