 Both men, and their often innovative followers (Abelard’s were the nominales, Gilbert’s the Porretani) in the second half of the century, also wrote on theology. Indeed, Gilbert’s surviving works are all theological, the most important of them a commentary on Boethius’s short theological treatises. Gilbert tried, unsuccessfully, to establish the method Boethius used in his Short Theological Treatises—of going as far as possible with parallels between natural phenomena and sacred mysteries, and pointing out where he has to stop—as standard. Abelard’s own particular theological ideas—which included an (arguably) rationalizing approach to the Trinity, and the view that, unlike humans, God cannot act otherwise than he does—were generally rejected, and some of them condemned. But his method of trying to reconcile apparently contradictory authoritative texts through conceptual analysis was widely adopted by his contemporaries and would form the basis for later medieval theology.
