What was open in/about early scholastic thought?

This chapter examines the meaning of the term 'aperire' ('to open') in the schools of the twelfth century and within early scholastic thought. It argues for a shift from a traditional understanding of opening as a revelation received from God, towards a more technical definition of opening as applying dialectical logic to a text. The act of opening was employed polemically, both in debates between scholastic masters and to distinguish Christian from Jewish exegetical practices.
