The medieval Church's concern with moral reform contributed to the emergence of a genre of literature in the thirteenth century dedicated to the vices and virtues. Inspired by monastic and scholastic traditions, treatises such as Laurent d'Orléans's Somme le roi encouraged the avoidance of sin and provided the faithful with a moral taxonomy that ultimately ensured their access to heaven. Marguerite Porete's Mirror of Simple Souls and Meister Eckhart's Discourses of Instruction challenge this virtue-centered approach to salvation. Relying on their (...) shared claim that the fall of the just man is in fact a virtue, this essay argues that their moral theology is grounded not on the a posteriori act of penance needed for salvation, but on the a priori consent of the will. This alternative view of moral life finds support in previous strands of the Christian tradition, and in particular in Peter Abelard's theory of intentionalism. (shrink)
