Abstract

This slender volume contains a rapid sketch of the development of the notions of conscience and synderesis in medieval thought. Its timeliness is vouched for by the fact that conscience, to which appeal is so often made today, has not been thus far a major theme of modern philosophy. Much of the book's information is quarried from O. Lottin's classic study, Psychologie et morale aux XIIe et XIIIe siècles, whose findings have been restated in terms that are meant to be "psychologically" accessible to the modern mind. The Preface calls attention to the undue neglect of medieval philosophy on the part of twentieth-century thinkers, many of whom still cling to the view that philosophy died with Aristotle and came to life again only with Descartes. It also laments the "party spirit" that once tended to characterize the Neo-Scholastic movement, as well as the one-sided emphasis on Thomas Aquinas within that movement. Potts has accordingly sought to broaden the scope of his inquiry by taking into consideration five widely different authors through whose writings one begins to glimpse the subtlety of the medieval teaching on this important topic: Jerome, who introduced the word "synderesis" into the debate ; Peter Lombard, whose Sentences provided the mandatory point of departure for all subsequent discussions of the subject; Philip the Chancellor, the author of the first medieval treatise on conscience; and, finally, Bonaventure and Thomas Aquinas, two of the writers who contributed most significantly to the further elaboration of the doctrine. By the author's own admission, numerous other theologians, whose names are listed in an appendix, could have been included in the roster or substituted for the ones that are included. The book is divided into two even parts, the first of which presents an analysis of the thought of each of the five theologians mentioned, and the second a selection of representative texts from their works. For the convenience of teachers, a "programme for a medieval-philosophy course on conscience" has been added under Appendix 2.
