Abstract
After the publication of Marcia Colish’s Peter Lombard in 1994, studies on the author of the Book of Sentences have entered a new phase. This article provides an assessment of the state of research in the field and makes suggestions for its further development. In an appreciation and critique of Marcia Colish’s contribution, it argues that Colish’s interpretation, for all its merit, errs on a number of points: the proofs of God’s existence, charity, and the structure of theological ethics are important examples. The second part of the essay considers the potential of research on the tradition of commentaries upon the Sentences. Given the central place that this genre of theological writing occupied in Christian thought between the twelfth and the sixteenth centuries, the Sentences commentaries could serve as a window upon the tradition. It is suggested that study of the literary form of the commentaries will shed much light on changes in the conception of theology which occurred in the period under consideration.
