Jean Buridan’s Logic


Book Description

Buridan was a brilliant logician in an age of brilliant logicians, sensitive to formal and philosophical considerations. There is a need for critical editions and accurate translations of his works, for his philosophical voice speaks directly across the ages to problems of concern to analytic philosophers today. But his idiom is unfamiliar, so editions and trans lations alone will not bridge the gap of centuries. I have tried to make Buridan accessible to philosophers and logicians today by the introduc tory essay, in which I survey Buridan's philosophy of logic. Several problems which Buridan touches on only marginally in the works trans lated herein are developed and discussed, citing other works of Buridan; some topics which he treats at length in the translated works, such as the semantic theory of oblique terms, I have touched on lightly or not at all. Such distortions are inevitable, and I hope that the idiosyncracies of my choice of philosophically relevant topics will not blind the reader to other topics of value Buridan considers. My goal in translating has been to produce an accurate renaering of the Latin. Often Buridan will couch a logical rule in terms of the grammatical form of a sentence, and I have endeavored to keep the translation consistent. Some strained phrases result, such as "A man I know" having a different logic from "I know a man. " This awkwardness cannot always be avoided, and I beg the reader's indulgence. All of the translations here are my own.




Medieval Modal Systems


Book Description

This book explores noteworthy approaches to modal syllogistic adopted by medieval logicians including Abélard, Albert the Great, Avicenna, Averröes, Jean Buridan, Richard Campsall, Robert Kilwardby, and William of Ockham. The book situates these approaches in relation to Aristotle's discussion in the Prior and Posterior Analytics, and other parts of the Organon, but also in relation to the thought of Alexander of Aphrodisias and Boethius on the one hand, and to modern interpretations of the modal syllogistic on the other. Problems explored include: Aristotle's doctrine of modal conversion, the pure and mixed necessity-moods, modal ecthesis, the pure and mixed contingency-moods, and Aristotle's use of counter-examples. Medieval logicians brought various concepts to bear on these problems, including the distinction between per se and per accidens terms, the notion of essential predication, the distinction between ut nunc and simpliciter propositions, the distinction between de dicto and de re modals, and the notion of ampliation. All these are examined in this book.




Logic: A History of its Central Concepts


Book Description

The Handbook of the History of Logic is a multi-volume research instrument that brings to the development of logic the best in modern techniques of historical and interpretative scholarship. It is the first work in English in which the history of logic is presented so extensively. The volumes are numerous and large. Authors have been given considerable latitude to produce chapters of a length, and a level of detail, that would lay fair claim on the ambitions of the project to be a definitive research work. Authors have been carefully selected with this aim in mind. They and the Editors join in the conviction that a knowledge of the history of logic is nothing but beneficial to the subject's present-day research programmes. One of the attractions of the Handbook's several volumes is the emphasis they give to the enduring relevance of developments in logic throughout the ages, including some of the earliest manifestations of the subject. - Covers in depth the notion of logical consequence - Discusses the central concept in logic of modality - Includes the use of diagrams in logical reasoning

John Buridan


Book Description

John Buridan (ca. 1300-1362) has worked out perhaps the most comprehensive account of nominalism in the history of Western thought, the philosophical doctrine according to which the only universals in reality are "names": the common terms of our language and the common concepts of our minds. But these items are universal only in their signification; they are singular entities like any other in reality. This book examines what is most intriguing to contemporary readers in Buridan's medieval philosophical system: his nominalist account of the relationship between language, thought and reality. The main focus of the discussion is Buridan's deployment of the Ockhamist conception of a "mental language" for mapping the complex structures of written and spoken human languages onto a parsimoniously construed reality. Concerning these linguistic structures, this book carefully analyzes Buridan's conception of the radical conventionality of written and spoken languages, in contrast to the natural semantic features of concepts. The discussion pays special attention to Buridan's token-based semantics of terms and propositions, his conception of existential import, ontological commitment, truth, and logical validity. Finally, the book presents a detailed discussion of how these logical devices allow Buridan to maintain his nominalist position without giving up Aristotelian essentialism or yielding to skepticism, and pays special attention to contemporary concerns with these issues.




The Reception of John Philoponus’ Natural Philosophy


Book Description

In some of his most famous works, John Philoponus (c. 490-570 CE) confronts numerous aspects of Aristotle's philosophy and science. Yet the influence of these reinterpretations and critiques remains under-examined. This volume fills this gap by uncovering the considerable impact of Philoponus' natural philosophy in both the medieval and Renaissance periods. Divided into three parts, the first part of the volume introduces central concepts in Philoponus' philosophy. Highlighting the areas of crossover as well as of disagreement with Aristotle, chapters dedicate specific attention to Philoponus' theories of place, matter and vacuum; his ideas of motion; his discussion of the heavens and the fifth element; and his anthropology. This is followed, in parts two and three, by a focus on Philoponus' reception in the Middle Ages and the Renaissance respectively. Shedding light on the scientific ideas circulating in these periods, international experts explore a range of topics from the renewal of Aristotelianism in the Arab world, through the medieval Byzantine and Latin traditions, to Philoponus' appearance in the early works of Galileo. Engaging with a number of Philoponus' key tracts, The Reception of John Philoponus' Natural Philosophy is both a much-needed study of Philoponus' influence and a revealing analysis of how Aristotelian science was received, adapted, critiqued and mediated throughout the Middle Ages and the Renaissance.

Contingency and Freedom


Book Description

During the seventies, there was a revival of systematic philosophy in general and of ontology in particular. At the same time, especially in Anglo-Saxon thinking, systematic philosophy interacted very creatively with the history of medieval philosophy. It seems to us that the work of John Duns Scotus (1266-1308) could substantially benefit these develop ments. Not only this, but his works cries out to be developed across the whole spectrum of theology -that science which, in the Middle Ages, ruled all others ('regina scientiarum'). This book is the outcome of several years of scholarship and friend ship during which, guided by Dr. A. Vos, we have studied the work of Scotus. Our research group is connected to the Theological Faculty of Utrecht and to the Dutch Franciscan Study Centre (Stichting Francis caans Studiecentrum). This study presents a translation and commentary of Lectura I 39, which, in our view, is noteable as one of the key texts in the history of systematic theology and philosophy. In this book we have used specialist language and argumentation, but at the same time have taken pains to make it useful to a circle of in terested readers wider than simply that of those well-versed in medieval scholasticism. In this way, we hope to present the difficult but instruc tive work of the 'subtle master' ('doctor subtilis') in such a way as to make it attractive to other scholars and students in theology and philoso phy.




The Moment of Change


Book Description

This book is a systematic history of one of the oldest problems in the philosophy of space and time: How is the change from one state to its opposite to be described? To my knowledge it is the first comprehensive book providing information about and analysis of texts on this topic throughout the ages. The target audience I envisaged are advanced students and scholars of analytic philosophy and the history of philosophy who are interested in the philosophy of space and time. Authors treated in this book range from Plato, Aristotle, the logicians of the late Middle Ages, Kant, Brentano and Russell to contemporary authors such as Chisholm, Hamblin, Sorabji or Graham Priest, taking into account such theories as interval semantics or paraconsistent logic. For the first time, two main questions about the moment of change are explicitly kept apart: Which (if any) of the opposite states does the moment of change belong to? And does it contain an instantaneous event? The texts are discussed within a clear framework of the main systematic options for describing the moment of change, sometimes using predicate logic extended by newly introduced logical prefixes. The last part contains a new suggestion of how to solve the problem of the moment of change. It is centred around a theory of instantaneous states which provides a new solution to Zeno's Flying Arrow Paradox.
