Does the soul have parts? What kind of parts? And how do all the parts make together a whole? Many ancient, medieval and early modern philosophers discussed these questions, thus providing a mereological analysis of the soul. The eleven chapters reconstruct and critically examine radically different theories. They make clear that the question of how a single soul can have an internal complexity was a crucial issue for many classical thinkers.

Ward examines Scotus's arguments for his distinctive version of hylomorphism, the view that at least some material objects are composites of matter and form. It considers Scotus's reasons for adopting hylomorphism, and his accounts of how matter and form compose a substance, how extended parts, such as the organs of an organism, compose a substance, and how other sorts of things, such as the four chemical elements and all the things in the world, fail to compose a substance. It highlights (...) the extent to which Scotus draws on his metaphysics of essential order to explain why some things can compose substance and why others cannot. Throughout the book, contemporary versions of hylomorphism are discussed in ways that both illumine Scotus's own views and suggest ways to advance contemporary debates. (shrink)

Among the various testimonia assembled by Iwakuma and Ebbesen to the twelfth-century school of philosophers known as the Nominales,Iwakuma Yukio and Sten Ebbesen, “Logico -Theological Schools from the Secon d Half of the 12th Century: A List of Sources,” Vivarium XXX (1992):173–210. four record their commitment to the apparently outrageous thesis that nothing grows. My aim in this essay is to explore the reasons the Nominale s had for maintaining this thesis and to investigate the role that the theory which (...) supported it played in the development of late twelfth- and early thirteenth-century debates over the character of the hypostatic union. My investigation concerns onl y one aspect of twelfth-century NominalismSince this group were apparently the first ever to be called ‘nominalists’ I think that we may justifiably capitalize the name of the theory to indicate that we are referring to their version of it. but once this part of their system is understood, we will be better able to characterise the whole and the way in which the views of the Nominales conflicted with those of their opponents. S o long as the testimonia remain few and rather slight such a reconstruction offers our only hope for finding the Nominales and their influence where their name has not been recorded. (shrink)

sProblems about the nature of integral parts and wholes were central to twelfth-century discussions of the individuation and persistence over time of both substances and artifacts. This paper examines in detail Abaelard’s contribution to these discussions arguing that Abaelard proposes a solution to these problems which preserves our common sense intuitions about identity over time. In Abaelard’s work we find an explicit solution to the problem of the identity over time of living things which appeals to the persistence of the (...) vegetative soul through the loss or addition of corporeal matter. In work from the school of the Montani we apparently also have an account of Abaelard’s solution to the problem of the identity over time of artifacts which distinguishes between the role of a part in an integral whole and the material which plays that role such that the role persists when the matter is replaced.

In the Logica Ingredientibus Abailard attacks the theory according to which universals are collections of individuals. This paper argues that Abailard's principal objection to this 'collective realism', viz, that it conflates universals with integral wholes, is actually quite strong, though it is generally overlooked by recent commentators. For implicit in this objection is the claim that the collective realist cannot provide a satisfactory account of predication. The reason for this is that integral wholes are not uniquely decomposable. In support of (...) thesis the author first explicates the medieval distinction between integral and subjective parts and then discusses its application to collective realism. (shrink)

Boethius was a Roman senator who rose to high office under the Gothic king Theoderic the Great. He translated into Latin all he knew of Plato and Aristotle, and was profoundly interested in the issues of theology and philosophy. The Consolations were written while he awaited the execution of a tyrannical death sentence. The Consolations of Philosophy have been translated into English by King Alfred, Geoffrey Chaucer, and Queen Elizabeth I. This scholarly study by Henry Chadwick, the first this century (...) since the War, has stimulated new interest in these remarkable works. (shrink)

Peter Abelard held two views that imply a form of Mereological Essentialism: first, a thing is nothing other than all its parts taken together and second, no thing has more parts at one time than it does at another. This paper situates Abelard’s theses within their historical context. The paper first examines Boethius’s suggestive remarks about the dependence of the whole upon its parts and it highlights several of the choices that were open to twelfth-century students of Boethius’s mereology. Then (...) there is a brief survey of Abelard’s understanding of Mereological Essentialism. Finally, the paper examines some of the more interesting challenges to Mereological Essentialism that were posed by Abelard’s contemporaries. The paper focuses in particular on a set of fragments that have been attributed to the school of Joscelin of Soissons. (shrink)

The nature and content of the thought of Duns Scotus (c. 1266-1308) remains largely unknown except by the expert. This book provides an accessible account of Scotus' theology, focusing both on what is distinctive in his thought, and on issues where his insights might prove to be of perennial value.

This book offers a brief, accessible introduction to the thought of Boethius. After a survey of Boethius's life and work, Marenbon explicates his theological method, and devotes separate chapters to his arguments about good and evil, fortune, fate and free will, and the problem of divine foreknowledge. Marenbon also traces Boethius's influence on the work of such thinkers as Aquinas and Duns Scotus.

The thirty chapters work through various fundamental metaphysical issues, sometimes focusing more on scholastic thought, sometimes on the seventeenth century.

This is a major new study of Thomas Aquinas, the most influential philosopher of the Middle Ages. The book offers a clear and accessible guide to the central project of Aquinas' philosophy: the understanding of human nature. Robert Pasnau sets the philosophy in the context of ancient and modern thought, and argues for some groundbreaking proposals for understanding some of the most difficult areas of Aquinas' thought: the relationship of soul to body, the workings of sense and intellect, the will (...) and the passions, and personal identity. Structured around a close reading of the treatise on human nature from the Summa theologiae and deeply informed by a wide knowledge of the history of philosophy and contemporary philosophy, this study will offer specialists a series of novel and provocative interpretations, while providing students with a reference commentary on one of Aquinas' core texts.

This volume provides the first critical edition of Boethius' _De divione_. It includes extensive prolegomena, a facing-page English translation, and detailed commentary. It contributes to our understanding of the transitional phase between ancient and medieval thought.

Peter Abelard is one of the greatest philosophers of the medieval period. Although best known for his views about universals and his dramatic love affair with Heloise, he made a number of important contributions in metaphysics, logic, philosophy of language, mind and cognition, philosophical theology, ethics, and literature. The essays in this volume survey the entire range of Abelard's thought, and examine his overall achievement in its intellectual and historical context. They also trace Abelard's influence on later thought and his (...) relevance to philosophical debates today. (shrink)

Aquinas, Ockham, and Burdan all claim that a person can be numerically identical over time, despite changes in size, shape, and color. How can we reconcile this with the Indiscernibility of Identicals, the principle that numerical identity implies indiscernibility across time? Almost all contemporary metaphysicians regard the Indiscernibility of Identicals as axiomatic. But I will argue that Aquinas, Ockham, and Burdan would reject it, perhaps in favor of a principle restricted to indiscernibility at a time.

What kind of entities are faculties? How are they related to the soul and to the entire living being? How can they be classified? And in what sense are they responsible for a large variety of activities? This chapter examines these questions, which were extensively discussed by scholastic authors, and focuses on the metaphysical models established by William of Auvergne, Thomas Aquinas, William of Ockham, and Francisco Suárez. It argues that there was no unified scholastic doctrine. While some authors (e.g. (...) Ockham) took the faculties to be mere ways of acting of the soul, others (e.g. Suárez) conceived of them as distinct entities with their own power. The latter theory gave rise to a new model of the soul—a model that presented it as a complex entity with many distinct causes. (shrink)

Theology is the preeminent academic discipline during the Middle Ages and, as a result, most of great thinkers of this period are highly trained theologians. Although this is common knowledge, it is sometimes overlooked that the systematic nature of medieval theology led its practitioners to develop full treatments of virtually every area within philosophy. Indeed, theological reflection not only provides the main context in which the medievals theorize about what we would now recognize as distinctively philosophical issues, but it is (...) responsible for some of their most significant philosophical contributions. To give just a few examples: it is problems with the Christian doctrine of the Incarnation that prompt medievals to develop the notions of ‘substance’ and ‘person’ in striking and original ways; it is problems with the doctrine of the Eucharist that lead them to consider the possibility of ‘accidents that do not inhere’; and it is problems of..
