 Sentences as a genre is a development of earlier collections of sayings or citations of the church fathers. Such collections, known as florilegia, were collections of citations organized around the order of scripture. The development of the scholastic sentences collection can be attributed jointly to Anselm of Laon, Abelard, and Peter Lombard. Anselm of Laon and his school, so famously criticized by Abelard in his Historia Calamitatum, can be credited with developing a critical approach to the authorities they cited; they sometimes disregarded or criticized opinions rather than always seeking to preserve them all (Colish 1994, 42–46). The next significant development is in the organization of these collections, from an organization following the order of scripture to an organization based on systematic questions of theology. Such a change brings speculative and philosophical questions to the fore, questions concerning the divine nature and metaphysics, and anthropological and ethical problems. Peter Abelard’s Sic et Non opposes authoritative quotations from church fathers on particular questions arranged in an order and on topics that are systematic rather than narrative. What Abelard attempted in the various versions of Theologia but did not ever manage successfully to do was to gather those various questions into a systematic organization and division of theology as a discipline. This was the achievement of Peter Lombard.
