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)

Histories of philosophy frequently depict the later eleventh century as the scene of a series of bouts between dialecticians and anti-dialecticians — Berengar vs. Lanfranc, Roscelin vs. Anselm — preliminaries to the twelfth century welterweight contest between Abelard and St. Bernard and — dare one say? — the thirteenth century heavy-weight championship between St. Thomas and St. Bonaventure.The bouts took place — no question about that — but whether the contestants can properly be characterized as dialecticians and anti-dialecticians is less (...) certain. Dialectics is logic, the third part of the trivium, and increasingly cultivated in the eleventh century; men like Berengar and Roscelin were plainly eager to apply the logical tools with which they had been equipped to the solution of intellectual problems. In particular they undertook the solution of certain central problems of theology — Berengar that of the Eucharist and Roscelin that of the Trinity — and it was this, we are told, that aroused the ire of the anti-dialecticians: if the aim of the dialecticians was to lay bare the mysteries of faith to the light of reason that of the anti-dialecticians was to protect those same mysteries from profanation.

ABELARD'S ethical theory, presented above all in his Ethics, is a version of what I'll call intentionalism': the view that the agent's intention determines the moral worth of an action. Now even in Abelard's day, the common understanding of morality seemed to endorse the following principle: (P) An agent should intend to Φ only if bringing about Φ would be good -/- But Abelard replaces (P) with its obverse, a principle he identifies as the rational core imbedded in traditional Christian (...) moral teaching: (P*) An agent should bring about Φ only if intending to Φ would be good Abelard's arguments against (P) and in support of (P*) are remarkably similar to those given by the most famous exponent of intentionalism, Kant. For Kant's ethical theory, especially as he presents in the first section of the Groundwork of the Metaphysics of Morals, identifies (P*) as the philosophical conception corresponding to the "common rational knowledge of morals." Abelard and Kant locate moral worth in features of the way the agent conceptualizes her performances, and each thinks that goodness is characterizable in terms of the form such conceptualization takes. Both are deeply indebted to Stoic ethics, familiar to each largely through Seneca's letters, and they share a common project: 'christianizing' Stoic metaethics so that the classical equation of virtue with happiness is revised to leave room for God and the Afterlife. -/- I'l l proceed as follows. In §1, Abelard's arguments against (P) will be canvassed. In §2, I'l l look at his arguments in favor of (P*) and a 'mediaeval categorical imperative'. In §3, a comparison with Kant's intentionalism should make the virtues of Abelard's theory apparent. In §4, I'l l discuss Abelard's failed attempt to baptize Stoicism. Finally, by way of conclusion, I'll offer a suggestion about why intentionalism, in any of its versions, is an ethical theory to take seriously. (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)

Adamsom offers a lively and accessible tour through 600 years of intellectual history, offering a feast of new ideas in every area of philosophy. He introduces us to some of the greatest thinkers of the Western tradition including Abelard, Anselm, Aquinas, Hildegard of Bingen, and Julian of Norwich.

Peter Abelard is nowadays credited as the first philosopher to recognize the problem of existential import. I argue that he does not recognize our modern problem, and that his own take on the logical issues that are said to give rise to the problem is much more interesting and subtle than has usually been acknowledged, depending on claims in the philosophy of language that are worthy of investigation in their own right—in the end, vindicating Abelard’s claims about the traditional (...)

Peter Adamson presents a lively introduction to six hundred years of European philosophy, from the beginning of the ninth century to the end of the fourteenth century. The medieval period is one of the richest in the history of philosophy, yet one of the least widely known. Adamson introduces us to some of the greatest thinkers of the Western intellectual tradition, including Peter Abelard, Anselm of Canterbury, Thomas Aquinas, John Duns Scotus, William of Ockham, and Roger Bacon. And (...) the medieval period was notable for the emergence of great women thinkers, including Hildegard of Bingen, Marguerite Porete, and Julian of Norwich. Original ideas and arguments were developed in every branch of philosophy during this period - not just philosophy of religion and theology, but metaphysics, philosophy of logic and language, moral and political theory, psychology, and the foundations of mathematics and natural science.

Abelardo eredita dall'Isagoge di Porfirio una questione filosofica fondamentale, relativa al problema degli universali, posto al centro della metafisica. Abelardo si pone subito fuori da questa linea interpretativa. L'A. esamina le risposte di Abelardo ai quattro quesiti di Porfirio formulati all'inizio dell'Isagoge punto per punto, attraverso l'esame di Dialectica, Logica «Ingredientibus» nella parte relativa al commento all'Isagoge, in rapporto con il Commentarius maior in Isagogen Porphyrii di Boezio, la Logica «Nostrorum petitioni sociorum», le Introductiones parvulorum, tentando di spodestare la metafisica (...) dalla sua posizione centrale in ambito filosofico.

This is the first comprehensive study of the philosophical achievements of twelfth-century Western Europe. It is the collaboration of fifteen scholars whose detailed survey makes accessible the intellectual preoccupations of the period, with all texts cited in English translation throughout. After a discussion of the cultural context of twelfth-century speculation, and some of the main streams of thought - Platonic, Stoic, and Arabic - that quickened it, comes a characterisation of the new problems and perspectives of the period, in scientific (...) inquiry, speculative grammar, and logic. This is followed by a closer examination of the distinctive features of some of the most innovative thinkers of the time, from Anselm and Abelard to the School of Chartres. A final section shows the impact of newly recovered works of Aristotle in the twelfth-century West. (shrink)

This is a useful collection of readings for a senior undergraduate or junior-level graduate course on universals. The selections are short, but generally self-contained, and thus accessible to readers unfamiliar with the literature. Most of the great contributors to the debate, from Plato to the early Russell, Husserl, and Heidegger, are well represented, with a good sampling of the medieval discussion in pieces from Abelard, St. Thomas, Duns Scotus, and Ockham. Postwar twentieth-century contributors include Quine, Carnap, Strawson, and David Pears; (...) and the text ends with a helpful bibliography of books and articles for further inquiry. (shrink)

The Origins of Anglican Moral Theology shows how Anglican moral theology draws on Abelard, Aquinas, Scotus, Luther and Calvin. Perkins, Hooker, Sanderson and Taylor express its flowering from 1590 to 1670.

In his commentary on Aristotle’s Peri hermeneias,1 Abelard distinguishes the form of an expression2 (oratio) from what it says, that is, its content. The content of an expression is its understanding (intellectus). This distinction is surely the most well-known and central idea in Abelard’s commentary. It provides him with the opportunity to distinguish statements (enuntiationes) from other kinds of expressions without implying a diference in their content, since the ability of a statement to signify something true or false (verum vel (...) falsum)3 cannot be found in its content. More precisely, Abelard distinguishes statements both from complete expressions (orationes perfectae) that are not statements but rather questions, requests, commands, etc. and from incomplete expressions, that is, mere word strings (orationes imperfectae), such as homo albus. These kinds of expressions, according to Abelard, do not differ in the understanding they present but in the way they present it. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories (...) and On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Though there has been much debate about whether Abelard's ethics are dangerously subjective or surprisingly absolutist, one thing is unanimous: they are intentionalist. The goal of this article is to parse out what should be meant by this claim, distancing his ethical account from the popular Kantian appraisal. Though much of the secondary literature on Abelard likens him to Kant, I argue that this is mistaken. For Abelard, an agent's intentions are informed by their affections—whether carnal or spiritual. This becomes (...) clear when contextualizing Abelard's use of intentio with a view to his Commentary on Romans. Using the account of intention I suggest—one nuanced by Abelard's own theological commitments and biblical exegesis—it will be clear that Abelard's ethics is not a case for the moral neutrality of the passions nor an ethic of pure reason.

Peter Abelard was one of the most influential writers and thinkers of the twelfth century, famed for his skill in logic as well as his romance with Heloise. His Collationes - or Dialogue between a Christian, a Philosopher, and a Jew - is remarkable for the boldness of its conception and thought.

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).

Spoken sentences have parts. Therefore they take time to speak. For instance, when you say, “Socrates is running”, you begin by uttering the subject term ("Socrates"), before carrying on to the predicate. But are the corresponding predications in thought also composite? And are such thoughts extended across time, like their spoken counterparts? Peter Abelard gave an affirmative response to both questions. Alberic of Paris denied the first and, as a corollary, denied the second. Here, I first set out Abelard’s (...) account. I then present a series of arguments against Abelard, reconstructed from (sometimes fragmentary) manuscripts associated with Alberic’s school. I conclude with an observation about present philosophy of language: this twelfth-century debate points to some undefended (and largely unstated) assumptions common to our latest thinking about propositions. I highlight this by presenting recent accounts of two philosophers with radically different outlooks: Jeffrey King and Peter Hanks. Both their accounts take many of the same things for granted, as the Alberican criticisms make plain. (shrink)

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)

These essays provide original reflections and new evidence for the lives and work of an outstanding medieval couple, Peter Abelard and Heloise. The main themes of David Luscombe's studies are the careers and the thought of Peter Abelard, his philosophy, theology and monastic teaching, his relationship in marriage and in religious life with Heloise and their correspondence. The essays, now brought together in a single volume, show how much is still to be learned from the presentation of new (...) evidence and the opening of new enquiries about the lives and calamities of Peter Abelard and Heloise.

In this paper, we examine Abelard’s model of the incarnation and place it within the wider context of his views in metaphysics and logic. In particular, we consider whether Abelard has the resources to solve the major difficulties faced by the so-called “compositional models” of the incarnation, such as his own. These difficulties include: the requirement to account for Christ’s unity as a single person, despite being composed of two concrete particulars; the requirement to allow that Christ is identical with (...) the pre-existent Son, despite the fact that the pre-existent Son is a (proper) part of the incarnate Christ; and finally the requirement to avoid Nestorianism, i.e., the position that Christ’s proper parts are persons in their own right. We argue that Abelard does have adequate solutions to these problems. In particular, we show that his theories of relations and predication can be put to use in defence of a compositional account of the incarnation. (shrink)

_Varieties of the Self_ discusses human perspectives of the Paraclete (founded in 1129) on sacrifice, intentionality, and views on body and soul. The anthropological approach connects different works written by Peter Abelard to views on the individual within this community.

Peter Abelard, Collationes, Edited and Translated by John Marenbon and Giovanni Orlandi.

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)

Peter Abelard is one of the best-known figures of mediæval intellectual history, if only because of the disastrous love affair with Heloise which ended in his castration by thugs in the pay of Heloise’s outraged uncle. He is also one of the most accessible, by virtue of his letters to Heloise and his lively account of his own life in the Historia calamitatum. However, while specialists have paid detailed attention to his ethics and to his logic, including his discussion (...) of the problem of universals, little has been written that presents an overview of his thought to a wider audience. In this book, John Marenbon sets out to do two things: to give us a general view of Abelard’s life and writings, and to present analyses of Abelard’s ontology, epistemology, and semantics, and of his ethical theory, particularly as it grows out of his theology. Marenbon hopes to show that Abelard was not merely a gifted logician and critic of poor arguments wherever they may be found, but a constructive philosopher in his own right. (shrink)

My article surveys philosophical discussions of Abelard over the last twenty years. Although Abelard has been a well-known figure for centuries, his most important logical works were published only in the twentieth century and, so I argue, the rediscovery of him as an important philosopher is recent and continuing. I concentrate especially on work that shows Abelard as the re-discoverer of propositional logic (Chris Martin); as a subtle explorer of problems about modality (Simo Knuuttila, Herbert Weidemann) and semantics (Klaus Jacobi); (...) as a metaphysician before the reception of Aristotle's Metaphysics (Peter King); and as an ethical thinker who echoes the Stoics (Calvin Normore) and anticipates Kant (Peter King).
