This book offers a major reassessment of Peter Abelard's modal logic and theory of modalities, presenting them as far more uniform and consistent than was until now recognized. Irene Binini offers new ways of connecting Abelard's modal views with other parts of his logic, semantics, metaphysics and theology. Further, the work also provides a comprehensive study of the logical context in which Abelard's theories originated and developed, by presenting fresh evidence about many 11th- and 12th-century sources that are still unpublished. (...) This analysis sheds new light on the relations between Abelard and ancient authors such as Aristotle, Boethius, and Priscian, as well as between Abelard and his contemporaries, such as Anselm of Canterbury, William of Champeaux, Joscelin of Soissons, and Alberic of Paris.

This is collection of Christian treatises written prior to the end of the sixteenth century.

New translations of the central mediaeval texts on the problem of universals are presented here in an affordable edition suitable for use in courses in mediaeval philosophy, history of mediaeval philosophy, and universals. Includes a concise Introduction, glossary of important terms, notes, and bibliography.

On several critical occasions in his philosophical and theological musings, we find Abelard having recourse to what is at heart the same philosophical simile -- in one instance drawing comparison to a stone statue, in another to a bronze statue, in a third to a wax image. The common point of comparison is obvious; each of these examples gives us a case where some physical material has come to receive some manner of shape. The doctrine illustrated by these means is (...) not, as might be supposed, a conventional Aristotelian form/matter metaphysics. (shrink)

This book focuses on Abelard’s logical-grammatical analysis of natural language. Tools of modern categorial grammar are employed to clarify many of the problems raised by historiography. The book’s ample analysis of grammatical sources and critical literature allows one to evaluate the progress which is at the basis of the forthcoming terministic logic. The book is aimed at scholars of medieval philosophy and historians of logic and linguistics.

Mediaeval logicians inherited from Boethius an account of conditional propositions and the syllogisms which may be constructed using them. In the following paper it is shown that there are considerable difficulties with Boethius' account which arise from his failure to understand the nature of compound propositions and in particular to provide for their negation. Boethius suggests that there are two different conditions which may be imposed for the truth of a conditional proposition but he really gives no adequate account of (...) how such propositions may be obtained. The true greatness of Peter Abaelard as a philosophical logician is revealed in what he is able to do with the material which he found in Boethius. It is shown that he developed a precise theory of conditionals giving an account of how true conditionals may be obtained and principles which may be used to reject others as false. Unlike Boethius Abaelard properly appreciates that conjunctions must be treated as logical units. Even he, however, falls victim to difficulties which arise when this connective is brought into contact with negation and the conditions which he lays down for the truth of a conditional. (shrink)

This chapter contains sections titled: Logic Metaphysics Ethics Philosophy of religion Abelard's place in medieval philosophy.

In the course of the debates on Priscian's notion of the perfect sentence, the philosopher Peter Abelard developed a theory that closely resembles modern accounts of propositional attitudes and that goes far beyond the established Aristotelian conceptions of the sentence. According to Abelard, the perfection of a sentence does not depend on the content that it expresses, but on the fact that the content is stated along with the propositional attitude towards the content. This paper tries to provide an analysis (...) and a consistent interpretation of Abelard's arguments within the framework of the mediaeval models of language and mind. (shrink)

I argue that Abelard was the author of the first theory of mental language in the Middle Ages, devising a “language of thought” to provide the semantics for ordinary languages, based on the idea that thoughts have linguistic character. I examine Abelard’s semantic framework with special attention to his principle of compositionality (the meaning of a whole is a function of the meanings of the parts); the results are then applied to Abelard’s distinction between complete and incomplete expressions, as well (...) as the distinction between sentences and the statements which the sentences are used to make. Abelard’s theory of mental language is shown to be subtle and sophisticated, the forerunner of the great theories of the fourteenth century. (shrink)

Like many of his medieval successors, Peter Abelard offers principles for ranking sins. Moral self-knowledge, after all, requires that we recognize not justour sinfulness, but also the extent of our offense. The most important distinction among sins is that between venial and mortal sins: venial sinners show less contempt and may also be victims of bad moral luck, and so they are far less blameworthy. However, the subjective principle which Abelard uses to protect the venial sinner from blame appears to (...) have absurd consequences: some agents whom we intuitively find saintly turn out to be mortal sinners, while other agents whom we intuitively judge wicked turn out to be mere venial sinners. I argue that Abelard suggests promising replies to these objections, but these replies themselves depend on controversial views about moral psychology. (shrink)

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)

In lieu of an abstract, here is a brief excerpt of the content:Abailard and the Problem of Universals JOHN F. BOLER ABAILARD t IS A CLEVERman, but in one respect he is just like the rest of us: Given one clear idea of which he is convinced, he tends to become intolerant, thinking the worst of everyone else. Abailard's clear idea goes something as follows. In what does universality consist? It consists, says Abailard, in the signifying of many things by (...) one sign? Abailard's predecessors had been searching for some thing which was universal. But a sign must signify many things to be universal; and furthermore, the sign itself, as a thing--a noise, gesture, or statue--is individual. ~ It may help to describe the model which crops up here and there in Abailard's examples and which, I think, dominates his analysis. Consider, then, a statue which is not meant to stand for any one particular individual: for example, the Minute Man at Concord, Massachusetts.* First of all, the statue is an individual thing. Second, just as a piece of metal, it need not stand for anything--anymore than a bird bath would, had the town council decided to build that instead. What is more, it is information from other sources which leads us to take the statue as "general" rather than as depicting some individual (like Nathan Hale). And even though the statue stands for "all" minute men, not only is the statue an individual thing but all those things for which it stands are (or were) individuals. And finally, we might also point out that the statue must be taken as signifying; it does not have "representative" qualities in quite the same way that it has properties like weight and shape. t The text of Abailard to which I have referred is: Peter Abaelards Philosophische Schrqte, herausgegeben yon Dr. Bernhard Geyer, I Die Logica "Ingredientibus,'" II Die Logica "'Nostrorum Petitioni Sociorum" which is to be found in Beitraege zur Geschichte der Philosophie und Theologie des Mittelalters, Band XXI (1933). A partial translation of this text appears in R. McKeon, Selections from Medieval Philosophers (New York: Scribners, 1929), II, 208-258. Hereafter I shall refer to the latin text as "G" followed by the page number and lines; and to the translation, where possible, as "'M" with the page number. 9Abailard feels that when Aristotle says that a universal is what is fitted for being predicated of many things, it is the signifying of many things which is at stake; and he chides Aristotle for seeming to ascribe universality to things as well as to words. G ~ (M 221). The reference to Aristotle is On Interpretation, 17a (38-40). *See note 7, below. 9I have interpolated on two passages: G 22t~-~ (M 241-242), and G 522*t-=. [37] 38 HISTORY OF PHILOSOPHY The upshot of Abailard's insight is that universality pertains to the interpretation of signs: the effort to locate universal things is misguided. Some want to say that the universal is a collection; but do collections signify their members? ~ Some want to say that the universal is a substance of which individuals are accidents; but is a substance predicated of its accidents? e And some want to say that universals are words--that is noises; but noises are also individual things. ~ In short, to signify or to show ("monstrare") pertains to words; to be signified or shown pertains to things. 8 And to transfer the properties of one to the other leads to hopeless difficulties. ~ One can understand Abailard's exultation (and exaltation) at having shown both sides of a seething controversy to be equally misguided? ~ But what then remains as the problem of universals? It is this: one would expect that every sign would have some subject which it signifies; but universals seem to lack a proper subject. And does this not mean that universals are fictions (like goat-stag or chimera)? = Having thus set out rather baldly what I take to be Abailard's "clear idea," let me now try to show more fully how he goes about establishing the problem and providing for a solution. Abailard's position on universals is set forth in his two logic books, both of which begin... (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)

This article aims to supplement our understanding of later developments within European universities, that is, Scholastic thought, by attending to how certain pre-Scholastics, namely, Peter Abelard and other twelfth-century philosophers, thought about artifacts and social constructions more generally. It focuses on the treatment of artifacts that can be cobbled together out of Abelard’s Dialectica. The article argues that Abelard attempts to sharply distinguish the world of things from the world of human-made objects. This is most apparent in his treatment of (...) creation and human acts of making. Yet there are places in his thought where we see some hesitancy. Many of Abelard’s peers seem to have drawn on the reasons why Abelard hesitates, and they blur the line between human-made objects such as houses and substances such as rocks and humans. Others seem to go further than Abelard—perhaps inspired by some of the thoughts that Abelard also entertains about social constructions such as days and speeches—and assert that even houses are merely convenient fictions.

This book offers a major reassessment of the philosophy of Peter Abelard (1079-1142) which argues that he was not, as usually presented, a predominantly critical thinker but a constructive one. By way of evidence the author offers new analyses of frequently discussed topics in Abelard's philosophy, and examines other areas such as the nature of substances and accidents, cognition, the definition of 'good' and 'evil', virtues and merit, and practical ethics in detail for the first time. The book also includes (...) a discussion of Abelard's life and works, and considers problems of chronology and canon (including the question of the authenticity of the correspondence with Heloise). '... not only an outstanding exposition of Abelard's philosophy, but a work that opens up for specialists and non-specialists the world of twelfth-century thought.' The Times Literary Supplement.

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)

Peter Abelard (1079 – 21 April 1142) [‘Abailard’ or ‘Abaelard’ or ‘Habalaarz’ and so on] was the pre-eminent philosopher and theologian of the twelfth century. The teacher of his generation, he was also famous as a poet and a musician. Prior to the recovery of Aristotle, he brought the native Latin tradition in philosophy to its highest pitch. His genius was evident in all he did. He is, arguably, the greatest logician of the Middle Ages and is equally famous as (...) the first great nominalist philosopher. He championed the use of reason in matters of faith (he was the first to use ‘theology’ in its modern sense), and his systematic treatment of religious doctrines are as remarkable for their philosophical penetration and subtlety as they are for their audacity. Abelard seemed larger than life to his contemporaries: his quick wit, sharp tongue, perfect memory, and boundless arrogance made him unbeatable in debate — he was said by supporter and detractor alike never to have lost an argument — and the force of his personality impressed itself vividly on all with whom he came into contact. His luckless affair with Héloïse made him a tragic figure of romance, and his conflict with Bernard of Clairvaux over reason and religion made him the hero of the Enlightenment. For all his colourful life, though, his philosophical achievements are the cornerstone of his fame. (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..
