The present study examines, on one hand, Philip the Chancellor’s work in the early 13th century on the nature of being as good, in the context of the development of his philosophical method. It deals with his position on the value of philosophical propositions to the understanding of the faith. On the other hand, the study presents Philip’s cosmic-anthropological concepts, particularly stressing the contribution of Platonic, Aristotelian and Hellenistic traditions to it.
