This special issue grew out of a small conference The Known & the Unknown: Exploring Twelfth-Century Philosophy, which was funded by the Carlsberg Foundation, hosted by the Saxo Institute, and held at the University of Copenhagen in April 2018. Its central topic was the many, mostly unexplored, commentaries on Aristotle, Boethius, and Porphyry that constitute the key textual evidence for a fascinating phenomenon that, although it played a pivotal role in the philosophical revival of Western Europe, remains frustratingly underexplored to this day: the logical schools of the twelfth century. The present introduction has two parts. In the first part, John Marenbon lays out the background to this special issue of Vivarium as a whole, explaining both what the philosophical project pursued by twelfth-century logicians was and how, and how far, the historical project of understanding it has progressed over the last two hundred years. In the second part, Heine Hansen briefly presents the issue and its contents.

Pagans and Philosophers explores how writers—philosophers and theologians, but also poets such as Dante, Chaucer, and Langland, and travelers such as Las Casas and Ricci—tackled the Problem of Paganism. Augustine and Boethius set its terms, while Peter Abelard and John of Salisbury were important early advocates of pagan wisdom and virtue. University theologians such as Aquinas, Scotus, Ockham, and Bradwardine, and later thinkers such as Ficino, Valla, More, Bayle, and Leibniz, explored the difficulty in depth. Meanwhile, Albert the Great inspired Boethius of Dacia and others to create a relativist conception of scientific knowledge that allowed Christian teachers to remain faithful Aristotelians. At the same time, early anthropologists such as John of Piano Carpini, John Mandeville, and Montaigne developed other sorts of relativism in response to the issue.

William of Ockham is known to be one of the major figures of the late Middle Ages. The scope and significance of his doctrine of human thought, however, has been a controversial issue among scholars in the last decade, and this book presents a full discussion of recent developments. Claude Panaccio proposes a richly documented and entirely original reinterpretation of Ockham's theory of concepts as a coherent blend of representationalism, conceptual atomism, and non reductionist nominalism, stressing in the process its special interest for current discussions in philosophy of mind and cognitive sciences.

Roberto Pinzani has written a closely-argued, highly original, valuable but difficult book. The Problem of Universals, indeed, is—and has been for nearly two centuries—the most frequently treated topic in medieval philosophy, and solutions to it proposed by two of the philosophers discussed here, Boethius and Abelard, have been examined countless times. But no one has before tried to cover the whole period, from circa 500 to circa 1150, looking in detail at a whole variety of writers. Moreover, what Pinzani has to say even about Boethius and Abelard is new.After a chapter setting out the problem, as he understands it, and looking especially at predication in Aristotle, Pinzani goes on to Boethius and then the...

Discusses Boethius's logical monographs: his treatises on division, on categorical syllogisms, and most importantly, his works on the theory of topical argument and on hypothetical syllogisms. The theory of topics, as developed in late antiquity and known almost entirely through Boethius, concerns the devising of arguments that rest on obvious general principles but are not, in their basic formulation, formally valid deductions. In his work on hypothetical syllogisms, Boethius seems to take account of Stoic propositional logic, but in fact, he does not properly grasp its principles. This chapter shows how Boethius's logical mongraphs fit with the Aristotelianizing approach of his commentaries.

After looking at the verse in the Consolation of Philosophy and other more literary aspects of it, this chapter proposes an interpretation of the work as a whole, which takes account of the fact that it is a prosimetrum – a genre in which the claims of learning were often challenged. Boethius, the chapter argues, regards philosophy with great respect, but considers it limited when it comes to providing a comprehensive and coherent understanding of the order of things. The differing attitudes of Boethius and Augustine, as Christians, to pagan Neoplatonism are contrasted.

Later Medieval Philosophy (1150-1350) provides an introduction to philosophy in the Latin West between 1150 and 1350. Part I describes the medieval thinker's intellectual and historical context, by examining the structure of courses in the medieval universities, the methods of teaching, the forms of written work, and the translation and availability of ancient Greek, Arab, and Jewish philosophical texts. Part II examines the nature of intellectual knowledge by explaining the arguments given by Aristotle, his antique commentators, and the Arab philosophers, Avicenna and Averroes.

Philosophy in the medieval Latin West before 1200 is often thought to have been dominated by Platonism. The articles in this volume question this view, by cataloguing, describing and investigating the tradition of Aristotelian logic during this period, examining its influence on authors usually placed within the Aristotelian tradition (Eriugena, Anselm, Gilbert of Poitiers), and also looking at some of the characteristics of early medieval Platonism. Abelard, the most brilliant logician of the age, is the main subject of three articles, and the book concludes with two more general discussions about how and why medieval philosophy should be studied.

The discussion of sameness and difference in the three versions of the Theologia has been analyzed by a number of recent writers (for example, Ian Wilks, JeffBrower, and Peter King). Despite some disagreements, they concur that Abelard’s views are best expressed in the Theologia christiana and that he is putting forward a theory that—perhaps adapted—can help philosophers now in considering the material constitution of objects. By contrast, I argue that his views, which should be seen as developing and reaching their final form in the Theologia “scholarium,” are much more closely linked than these scholars have thought to the particular theological problems involved in discussing the Trinity.

Volume 2 covers one of the richest eras for the philosophical study of religion. Covering the period from the 6th century to the Renaissance, this volume shows how Christian, Islamic and Jewish thinkers explicated and defended their religious faith in light of the philosophical traditions they inherited from the ancient Greeks and Romans. The enterprise of 'faith seeking understanding', as it was dubbed by the medievals themselves, emerges as a vibrant encounter between - and a complex synthesis of - the Platonic, Aristotelian and Hellenistic traditions of antiquity on the one hand, and the scholastic and monastic religious schools of the medieval West, on the other
