This book studies medieval theories of free will, including explanations of how angels - that is, ideal agents - can choose evil.

In this book Tobias Hoffmann studies the medieval free will debate during its liveliest period, from the 1220s to the 1320s, and clarifies its background in Aristotle, Augustine, and earlier medieval thinkers. Among the wide range of authors he examines are not only well-known thinkers such as Thomas Aquinas, Duns Scotus, and William of Ockham, but also a number of authors who were just as important in their time and deserve to be rediscovered today. To shed further light on their theories of free will, Hoffmann also explores their competing philosophical explanations of the fall of the angels, that is, the hypothesis of an evil choice made by rational beings under optimal psychological conditions. As he shows, this test case imposed limits on tracing free choices to cognition. His book provides a comprehensive account of a debate that was central to medieval philosophy and continues to occupy philosophers today.

This book presents in translation writings by six medieval philosophers which bear on the subject of conscience. Conscience, which can be considered both as a topic in the philosophy of mind and a topic in ethics, has been unduly neglected in modern philosophy, where a prevailing belief in the autonomy of ethics leaves it no natural place. It was, however, a standard subject for a treatise in medieval philosophy. Three introductory translations here, from Jerome, Augustine and Peter Lombard, present the loci classici on which subsequent discussions drew; there follows the first complete treatise on conscience, by Philip the Chancellor, while the two remaining translations, from Bonaventure and Aquinas, have been chosen as outstanding examples of the two main approaches which crystallised during the thirteenth century.

Among the great philosophers of the Middle Ages Aquinas is unique in pursuing two apparently disparate projects. On the one hand he developed a philosophical understanding of Christian doctrine in a fully integrated system encompassing all natural and supernatural reality. On the other hand, he was convinced that Aristotle's philosophy afforded the best available philosophical component of such a system. In a relatively brief career Aquinas developed these projects in great detail and with an astonishing degree of success. In this volume ten leading scholars introduce all the important aspects of Aquinas' thought, ranging from its historical background and dependence on Greek, Islamic, and Jewish philosophy and theology, through the metaphysics, epistemology and ethics, to the philosophical approach to Biblical commentary.

This book offers a major reassessment of the philosophy of Peter Abelard (1079-1142) which shows that he was a far more constructive and wider-ranging thinker than has usually been supposed. It combines detailed historical discussion, based on published and manuscript sources, with philosophical analysis which aims to make clear Abelard's central arguments about the nature of things, language and the mind, and about morality. Although the book concentrates on these philosophical questions, it places them within their theological and wider intellectual context.

In this book, Robert Sokolowski argues that being a person means to be involved with truth. He shows that human reason is established by syntactic composition in language, pictures, and actions and that we understand things when they are presented to us through syntax. Sokolowski highlights the role of the spoken word in human reason and examines the bodily and neurological basis for human experience. Drawing on Husserl and Aristotle, as well as Aquinas and Henry James, Sokolowski here employs phenomenology in a highly original way in order to clarify what we are as human agents.

This book studies medieval theories of angelology insofar as they made groundbreaking contributions to medieval philosophy. It centers on the period from Bonaventure to Ockham while also discussing some original positions by earlier thinkers.

Aristotle's Nicomachean Ethics is the text which had the single greatest influence on Aquinas's ethical writings, and the historical and philosophical value of Aquinas's appropriation of this text provokes lively debate. In this volume of new essays, thirteen distinguished scholars explore how Aquinas receives, expands on and transforms Aristotle's insights about the attainability of happiness, the scope of moral virtue, the foundation of morality and the nature of pleasure. They examine Aquinas's commentary on the Ethics and his theological writings, above all the Summa theologiae. Their essays show Aquinas to be a highly perceptive interpreter, but one who also brings certain presuppositions to the Ethics and alters key Aristotelian notions for his own purposes. The result is a rich and nuanced picture of Aquinas's relation to Aristotle that will be of interest to readers in moral philosophy, Aquinas studies, the history of theology and the history of philosophy.

What are angels? Where were they first encountered? Can we distinguish angels from gods, fairies, ghosts, and aliens? And why do they remain so popular? This Very Short Introduction investigates stories and speculations about angels in religions old and new, in art, literature, film, and the popular imagination.
