Examines Augustine's view of the will and the self and explores parallels between Augustine's and Harry Frankfurt's hierarchical accounts of personhood. Throws new light on Augustine's views on moral responsibility by showing that even if Augustine may have abandoned certain libertarian assumptions as to the nature of human free will in his mature works, he retains the underlying view of personhood as dependent on a capacity for a certain form of second-order desiring.

Anselm of Canterbury (1033–1109) holds that freedom of the will is a necessary condition for moral responsibility. This condition, however, turns out to be trivially fulfilled by all rational creatures at all times. In order to clarify the necessary conditions for moral responsibility, we must look more widely at his discussion of the nature of the will and of willed action. In this paper, I examine his theory of voluntariness by clarifying his account of the sin of Satan in De casu diaboli. Anselm agrees with Augustine that the sinful act cannot be given a causal explanation in terms of a distinct preceding act of will or desire or choice. He thus rejects volitionalist accounts of Satan's sin and thus of voluntary action in general. He moves beyond his predecessor, however, in insisting on the necessity of an explanation in terms of reasons, and his theory of the dual nature of the rational will is designed to meet this demand. A comparison of Satan's case with the case of the miser of De casu diaboli 3, finally, shows that Anselm's account requires that acts of the will or ‘willings’ qualify as voluntary, a suggestion as interesting as problematic.

This book is a collection of studies on topics related to subjectivity and selfhood in medieval and early modern philosophy. The individual contributions approach the theme from a number of angles varying from cognitive and moral psychology to metaphysics and epistemology. Instead of a complete overview on the historical period, the book provides detailed glimpses into some of the most important figures of the period, such as Augustine, Avicenna, Aquinas, Descartes, Spinoza, Leibniz and Hume. The questions addressed include the ethical problems of the location of one's true self and the proper distribution of labour between desire, passion and reason, and the psychological tasks of accounting for subjective experience and self-knowledge and determining different types of self-awareness.
