This edited volume presents new lines of research dealing with the language of thought and its philosophical implications in the time of Ockham. It features more than 20 essays that also serve as a tribute to the ground-breaking work of a leading expert in late medieval philosophy: Claude Panaccio. Coverage addresses topics in the philosophy of mind and cognition (externalism, mental causation, resemblance, habits, sensory awareness, the psychology, illusion, representationalism), concepts (universal, transcendental, identity, syncategorematic), logic and language (definitions, syllogisms, modality, supposition, obligationes, etc.), action theory (belief, will, action), and more. A distinctive feature of this work is that it brings together contributions in both French and English, the two major research languages today on the main theme in question. It unites the most renowned specialists in the field as well as many of Claude Panaccio’s former students who have engaged with his work over the years. In furthering this dialogue, the essays render key topics in fourteenth-century thought accessible to the contemporary philosophical community without being anachronistic or insensitive to the particularities of the medieval context. As a result, this book will appeal to a general population of philosophers and historians of philosophy with an interest in logic, philosophy of language, philosophy of mind, and metaphysics.

The notion that human thought is structured like a language, with a precise syntax and semantics, has been pivotal in recent philosophy of mind. Yet it is not a new idea: it was systematically explored in the fourteenth century by William of Ockham and became central in late medieval philosophy. Mental Language examines the background of Ockham's innovation by tracing the history of the mental language theme in ancient and medieval thought. Panaccio identifies two important traditions: one philosophical, stemming from Plato and Aristotle, and the other theological, rooted in the Fathers of the Christian Church. The study then focuses on the merging of the two traditions in the Middle Ages, as they gave rise to detailed discussions over the structure of human thought and its relations with signs and language. Ultimately, Panaccio stresses the originality and significance of Ockham's doctrine of the oratio mentalis (mental discourse) and the strong impression it made upon his immediate successors.

This book begins with standard ontological topics--such as the nature of existence--and of metaphysics generally, such as the status of universals, form, and accidents. What is the proper subject matter of metaphysical speculation? Are essence and existence really distinct in bodies? Does the body lose its unifying form at death? Can an accident of a substance exist in separation from that substance? Are universals real, and, if so, are they anything more than general concepts? Among the figures it examines are Thomas Aquinas, John Duns Scotus, William of Ockham, Walter Chatton, John Buridan, Dietrich of Freiburg, Robert Holcot, Walter Burley, and the 11th-century Islamic philosopher Ibn-Sina (Avicenna).There is also an emphasis on metaphysics broadly conceived. Thus, additional discussions of connected topics in medieval logic, epistemology, and language provide a fuller account of the range of ideas included in the later medieval worldview.

The Middle Ages span a period of well over a millennium: from the emperor Constantine's Christian conversion in 312 to the early sixteenth century. During this time there was remarkable continuity of thought, but there were also many changes made in different philosophies: various breaks, revivals and rediscoveries. David Luscombe's history of Medieval Thought steers a clear path through this long period, beginning with three great influences on medieval philosophy: Augustine, Boethius, and Pseudo-Denis, and focusing on Alcuin, then Anselm, Abelard, Aquinas, Ockham, Duns Scotus, and Eckhart amongst others from the twelfth to the fifteenth century. Medieval philosophy is widely regarded as having a theological and religious orientation, but more recently attention has been given to the early study of logic, language, and the philosophy of science. This history therefore gives a fascinating insight into medieval views on aspects such as astronomy, materialism, perception, and the nature of the soul, as well as of God.

Richard Cross provides the first complete and detailed account of Duns Scotus's theory of cognition, tracing the processes involved in cognition from sensation, through intuition and abstraction, to conceptual thought. He provides an analysis of the ontological status of the various mental items (acts and dispositions) involved in cognition, and a new account of Scotus on nature of conceptual content. Cross goes on to offer a novel, reductionist, interpretation of Scotus's view of the ontological status of representational content, as well as new accounts of Scotus's opinions on intuitive cognition, intelligible species, and the varieties of consciousness. Scotus was a perceptive but highly critical reader of his intellectual forebears, and this volume places his thought clearly within the context of thirteenth-century reflections on cognitive psychology, influenced as they were by Aristotle, Augustine, and Avicenna. As far as possible, Duns Scotus's Theory of Cognition traces developments in Scotus's thought during the ten or so highly productive years that formed the bulk of his intellectual life.

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

This introduction to philosophy in the Latin West between 1150 and 1350 combines an historical approach, which concentrates on the sources, forms and backgrounds of the medieval works, with philosophical analysis of thirteenth and fourteenth-century writing in terms comprehensible to a modern reader. Part One looks at the intellectual and historical context of medieval thought. It examines the courses in the medieval universities; the methods of teaching; the forms of written work; the logical techniques used for argument and analysis; the translation and the availability of Ancient Greek, Arab and Jewish philosophical texts; the challenges the new material presented and the various ways in which Western thinkers responded to them. Part Two focuses on one important problem in later medieval thought: the nature of intellectual knowledge. It explains the arguments given by Aristotle, his antique commentators and the Arab philosophers Avicenna and Averroes, and traces how a series of Western thinkers, including Thomas Aquinas and William of Ockham, developed, modified or rejected them.
