Finite agents such as human beings have reasoning and updating processes that are extended in time; consequently, there is always some lag between the point at which we gain new reasons and the point at which our attitudes have fully responded to those reasons. This phenomenon, which I call rational delay, poses a threat to the most common ways of formulating rational requirements on our attitudes, which do not allow rational beings to exhibit such delay. In this paper, I show (...) first how this problem undermines synchronic formulations of rational norms. Then I show how it likewise undermines the most natural diachronic modifications of these norms. Ultimately, I argue that a successful account of rational delay will reject norms that directly govern attitudes or states of mind like belief and intention altogether, in favor of norms that fundamentally concern temporally extended rational processes like deliberation.

The dispute in philosophical decision theory between causalists and evidentialists remains unsettled. Many are attracted to the causal view’s endorsement of a species of dominance reasoning, and to the intuitive verdicts it gets on a range of cases with the structure of the infamous Newcomb’s Problem. But it also faces a rising wave of purported counterexamples and theoretical challenges. In this paper I will describe a novel decision theory which saves what is appealing about the causal view while avoiding its (...) most worrying objections, and which promises to generalize to solve a set of related problems in other normative domains.

In this paper, I enter the debate between those who hold that our normative uncertainty matters for what we ought to do, and those who hold that only our descriptive uncertainty matters. I argue that existing views in both camps have unacceptable implications in cases where our descriptive beliefs depend on our normative beliefs. I go on to propose a fix which is available only to those who hold that normative uncertainty matters, ultimately leaving the challenge as a threat to (...) recent skepticism about such views.

There has been considerable philosophical debate in recent years over a thesis called epistemic permissivism. According to the permissivist, it is possible for two agents to have the exact same total body of evidence and yet differ in their belief attitudes towards some proposition, without either being irrational. However, I argue, not enough attention has been paid to the distinction between different ways in which permissivism might be true. In this paper, I present a taxonomy of forms of epistemic permissivism (...) framed as the upshot of different ways one might respond to a basic argument against the view from Roger White. I then introduce a new type of permissive view which the contemporary debate has completely ignored and which is made available when we reject a widespread and largely unexamined background commitment to static rational norms connecting beliefs and evidence in favor of dynamic norms governing processes of consideration. I show how the dynamic strategy of rejecting static norms on belief opens the door to a new kind of permissivism which is both independently attractive and especially well-placed to answer worries that have been raised against traditional permissivist views.

On the face of it, in ordinary practices of rational assessment, we criticize agents both for the combinations of attitudes, like belief, desire, and intention, that they possess at particular times, and for the ways that they behave cognitively over time, by forming, reconsidering, and updating those attitudes. Accordingly, philosophers have proposed norms of rationality that are synchronic—concerned fundamentally with our individual time-slices, and diachronic—concerned with our temporally extended behaviour. However, a recent movement in epistemology has cast doubt on the (...) very existence of requirements of the latter type. My aim in this paper is to address what I take to be the most direct and general recent attack on diachronic epistemic rationality, the arguments for so-called ‘time-slice epistemology’ by Brian Hedden. I argue that Hedden's attempt to motivate the rejection of diachronic rational norms ultimately fails, and in particular that an independently attractive view about the nature of such norms, namely one on which such norms govern processes, escapes his assault unscathed.

In this paper, I develop an approach to population ethics which explains what we are permitted to do in virtue of the possible complaints against our action. This task is made difficult by a serious problem that arises when we attempt to generalize the view from two-option to many-option cases. The solution makes two significant moves – first, accepting that complaints are essentially pairwise comparative, and second, reimagining decision-making as a tournament between options competing two at a time. The right (...) view about when one option defeats another with respect to complaints, paired with the right view about how to pick the winners of the tournament given the relations of defeat, leads to a uniquely attractive view in the person-affecting tradition.

Traditional rule consequentialism faces a problem sometimes called the ideal world objection—the worry that by looking only at the consequences in worlds where rules are universally adhered to, the theory fails to account for problems that arise because adherence to rules in the real world is inevitably imperfect. In response, recent theorists have defended sophisticated versions of rule consequentialism which are sensitive to the consequences in worlds with less utopian levels of adherence. In this paper, I argue that these attempts (...) underestimate the problem they are designed to avoid—the worry about ideal worlds is only one manifestation of a deeper and more general problem, the distant world objection, which threatens not only the sophisticated revisions of rule consequentialism, but any view which determines what we ought to do by evaluating worlds that differ from ours in more than what is up to us.

One popular defence of moral omnivorism appeals to facts about the indirectness of the diner’s causal relationship to the suffering of farmed animals. Another appeals to the claim that farmed animals would not exist but for our farming practices. The import of these claims, I argue, has been misunderstood, and the standard arguments grounded in them fail. In this paper, I develop a better argument in defence of eating meat which combines resources from both of these strategies, together with principles (...) of population ethics, and discuss its implications for which sorts of meat it is permissible to eat. According to the diner’s defence, there is an asymmetry between producers and consumers of meat. Producers can prevent the suffering of animals without preventing their existence, but consumers cannot. This asymmetry grounds a defence against harm-based objections to eating meat which is available to the consumer alone, and which avoids the controversial commitments about moral status or the interests of nonhuman animals endemic to existing attempts to justify omnivorism.

According to a family of views under the label of epistemic conservatism, the fact that one already believes something can make it rational to continue to believe it. A number of philosophers have found conservatism attractive, but traditional views are vulnerable to several powerful criticisms. In this paper, I develop an alternative to standard views by identifying a widespread assumption shared by conservatives and their critics - that rational norms govern states of mind like belief, and showing how rejecting this (...) assumption in favor of a process-oriented approach opens the door to a new, dynamic form of conservatism which preserves its core motivations while avoiding its traditional objections.

An Eternity 1988 Book of the Year! Since its publication, the New Dictionary of Theology has rapidly established itself as a standard, authoritative reference work in systematic and historical theology. More than 630 articles cover a variety of theological themes, thinkers and movements: from creation to the millennium from Abelard to Zwingli from Third World liberation theology to South African Dutch Reformed theology Firmly anchored in the evangelical tradition, the NDOT is nevertheless wide-ranging in its scope. Over 200 contributors, (...) experts in their individual fields, offer both Western and international perspective. Concise and comprehensive, biblically grounded and historically informed, even-handed and free from unduly technical language, this dictionary has been praised by general readers, pastors and scholars.

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)

The discussion of universals in Peter Abelard’s Logica ‘Ingredientibus’ has been interpreted in many ways. Of particular controversy has been the proper way to interpret his use of the term status. In this paper I offer an interpretation of status by comparing Abelard’s account of knowledge of universals to Edmund Husserl’s presentations of categorial and eidetic intuition. I argue that status is meant to be understood as something like an ideal object, in Husserl’s sense of the term. First, (...) I present Abelard’s discussion of status and distinguish this term from universals, things, acts of understanding, and forms. Next, I consider Husserl’s account of categorial and eidetic intuition. Finally, I draw parallels between the two while showing how an interpretation of status as ideal object overcomesthe interpretive problems encountered by other commentators on Abelard. (shrink)

Abelard repeatedly claims that no thing can survive the gain or loss of parts. I outline Abelard’s reasons for holding this controversial position. First, a change of parts compromises the matter of the object. Secondly, a change in matter compromises the form of the object. Given that both elements of an object are compromised by any gain or loss of a part, the object itself is compromised by any such change. An object that appears to survive change is (...) really a series of related, but non-identical, objects. I argue that, for Abelard, this series of objects is not itself an object. Finally, I examine an apparent exception to Abelard’s claim that no thing can survive a gain or loss of parts, and I show that this specific case does not undermine his general thesis. (shrink)

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)

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. (shrink)

In this essay, I offer an interpretation of Abelard's Historia Calamitatum and letters exchanged with Heloise, arguing that both are informed by the attempt to look below the surfaces of language, self, and action to a reality beneath and to achieve authenticity, by which I mean coherence between surface and depth. This reading shows an emerging sense of self and self-knowledge based on the relationship between external act and internal intention. While using traditional medieval narrative forms, I argue, (...) class='Hi'>Abelard gives his story a modern-sounding autobiographical twist: that its moral is about matching outer to inner self. While the project is never complete, the search itself becomes an identity; Abelard achieves authenticity in his rejection of all the models of it that were available to him. This is not done to unmask a self without place or parallel but to make the case for a new way of life in a new community for the inner self who is truly seeking God. Thus, like Augustine before and Rousseau after him, Abelard writes about his own life with a philosophical aim: to display the nature of what it is to be human and to make claims about how human life ought to be lived. (shrink)

For Abelard, the notion of “intention” (intentio, attentio) plays a central and important role in his cognitive and ethical theories. Is there any philosophical connection between its uses in these contexts? In recent publications, Constant Mews has argued that the cognitive and ethical senses of “intention” are related (namely, the cognitive sense evolves into the ethical sense), and that Abelard is repeatedly led to focus on intentions throughout his career due to the influence of Heloise. Here I evaluate (...) Mews’s arguments by examining and comparing the cognitive and ethical senses of the term. Although the basis for Mews’s claim seems to be false, I argue that there is nonetheless an important philosophical relationship between cognitive and ethical intentiones in Abelard’s thought, there cognition of which leads to a new and more precise understanding of his ethical theory of intention. (shrink)

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 Square of Opposition. (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 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)

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 (...) class='Hi'>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)

Peter Abelard's claim that universals are only words is well known, yet its metaphysical bearing for Abelard's philosophy is much disputed. Peter King has recently suggested that Abelard's nominalism is only an element of his larger irrealist metaphysic. Against this interpretation, I argue that Abelard's view is better understood as a form of moderate realism and a development of the solution attempted by Boethius in his Second Commentary on Porphyry's Isagoge. Both Abelard and Boethius clearly (...) deny the independent existence of universals, yet they should not be called irrealists, since they agree that universal words or concepts have a firm basis in real, individual things. (shrink)

The notion of nature is central not only to Abelard’s theory of cognition and to his treatment of universals, but also to Abelard’s modal logic, to his discussion of future contingents and to his theory of conditionals. In this essay, I emphasize how the notion of nature—despite its pervasiveness in Abelard’s philosophy and despite the attention that has been paid to it—still raises puzzling questions to interpreters. One of these puzzles has to do with Abelard’s idea (...) that different individuals may be “of a same nature,” a claim that according to some is hardly compatible with the nominalist position he endorsed. Another interpretative issue is raised by Abelard’s claims in De Intellectibus that substances have more than one nature, and that we might consider things as being of a different nature depending on which of their properties we pay attention to. Given Abelard’s essentialist framework, his assertions on the multiplicity of natures associable to a single individual may sound perplexing. Other issues that I take into account are Abelard’s attribution of natures to non-existent things such as chimaeras or horned men, and his remarks concerning the accessibility of natures to our knowledge. (shrink)

In the "Ethics", Abelard discusses the example of a judge who knowingly convicts an innocent defendant. He claims that this judge does rightly when he punishes the innocent man to the full extent of the law. Yet this claim seems counterintuitive, and, at first glance, contrary to Abelard’s own ethical system. Nevertheless, I argue that Abelard’s ethical system cannot be viewed as completely subjective, since the rightness of an individual act of consent is grounded in objective standards (...) established by God. Likewise, any particular civil government must derive its authority objectively from the natural and/or Christian laws, which ground its possibility and function. In this paper, I examine Abelard’s explication of the natural law, discoverable through reason, and the divine laws, knowable only through revelation, in order to explore what form an adequate civil law would have to take under which the judge could be said to have acted rightly. (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).

This article examines different medieval explanations of the causes of moral goodness, principally the end of the agent and the object of the action. Special attention is given to Thomas Aquinas, who considers the end (that which is willed) to be not only the origin of moral goodness, but also its main criterion. Peter Abelard, whose ethics I argue to be non-subjectivist, had developed a similar theory, though the vocabulary he uses is not very refined. By contrast, for Albert (...) and Duns Scotus, the end is accidental to the moral act. The importance of this study is to shed light on the subjective and objective criteria by which to evaluate the morality of actions. (shrink)

This paper is part of a larger project of recovering the work of women thinkers. Heloise has traditionally been read as either a foil of Abelard or his intellectual appendage. In this paper, I present her views on love, religious devotion, and language as an alternative to philosophic method as it is conceived by Abelard.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Possibility and Necessity in the Time of Peter Abelard by Irene BininiWolfgang LenzenIrene Binini. Possibility and Necessity in the Time of Peter Abelard. Investigating Medieval Philosophy Series. Leiden: Brill, 2021. Pp. xii + 326. Hardback, $166.00.This book is an impressive work written by a young Italian scholar who received her PhD only five years ago in Pisa. It is divided into three parts. Part 1 gives (...) a survey of "Early 12th-Century Debates on Modal Propositions"; part 2 is devoted to "Abelard's Modal Logic"; [End Page 327] part 3 deals with the views of "Abelard on the Metaphysics and Epistemology of Modalities." The author displays a profound knowledge of the relevant literature. The primary sources comprise twenty manuscripts preserved in various European libraries, plus forty-eight printed works (from Abelard to William of Sherwood). The list of secondary sources contains altogether 136 items from A (Astroh) to Z (Zagzebski), but, interestingly, it does not mention a monograph that, by its very title, claims to give an exposition of Abelard's logic, namely Maria Teresa Beonio-Brocchieri Fumagalli's La Logica di Abelardo (Firenze: La Nuova Italia, 1964).As far as I can judge (as a nonnative English-speaker), the linguistic quality of Binini's book is quite good. The explanations in the main text, including the translations from Latin sources, are easily comprehensible, and the many quotations (distributed over no less than 655 footnotes) are almost without any fault. Thus, the book rightly deserves inclusion in the prestigious series Investigating Medieval Philosophy. Yet, at least according to my taste, the book contains many redundancies. Again and again, the author first explains a certain issue at some length, then confirms the correctness of her interpretation by means of a longer (English) quotation, and finally reconfirms it by fully quoting the Latin text in the footnotes.As Binini explains in the book's concluding chapter, her aim is to present "an all-encompassing reflection on [Abelard's] works on modalities" and "a comparison between these works and the parallel reflections advanced by other masters and logicians in the early 12th century" (308). She undoubtedly achieves this goal. The comparison of Abelard's views on possibility and necessity with the views of other logicians is mainly carried out in chapters 1–3. Ancient and early medieval logicians such as, in particular, the Stoics and Boethius favored the basic idea that "something," p, is necessary if and only if p is always the case (or true). Accordingly, p is possible if and only if p is at least sometime the case. Abelard, however, was not willing to accept that each possibility has to become realized at some time. He instead offered a "nature-based characterization of possibility" that can "account for unrealized, past, counterfactual, and even unactualizable possibilities" (308). Abelard's idea is that something, x, is possibly a P if and only if the property of being P is compatible with the nature of x. Hence this view basically amounts to a de re conception of possibility that attributes modalities to things, while the temporal view attributes modal properties primarily to propositions (or states of affairs) and hence can be labeled de dicto (or de sensu).Let us now turn to Binini's twofold aim (as formulated on the back cover of her book) to present a "uniform and consistent" reassessment of Abelard's theory of modalities and of his modal logic. The former task is tackled in chapters 8–10. After summarizing, in chapter 8, Abelard's general views on "Nature and Modalities," chapter 9 is devoted to a detailed discussion of the "Many Senses of Possibility." In five consecutive sections, Binini investigates the conception of (1) possibility as "non-repugnancy with nature" (illustrated by the thesis that "any man can be a bishop" [235]); (2) unrealizable but "conceivable" possibilities (such as the existence of humans lacking the ability to laugh [240]); (3) determinate potencies (like that of an amputee who nevertheless "can walk" [248]); (4) past and counterfactual potencies (like that of a blind person who might be able to see); and (5) other puzzling de re possibilities (such as "irrational humans" [261]).The final...

This paper reconstructs a controversy between a pupil of Alberic of Paris and Peter Abelard which illustrates two competing ways of reconciling different ancient traditions. I shall argue that their accounts of the relation between sentences and thoughts are incompatible with one another, although they rely on the same set of sources. The key to understanding their different views on assertive and non-assertive sentences lies in their disparate views about the structure of thoughts: whereas Abelard takes thoughts to (...) be compositional, the opponent's arguments seem to rely on the premise that the mental states which correspond to sentences cannot be compositional in the way that Abelard suggested. Although, at a first glance, Abelard's position appears to be more coherent, it turns out that his opponent convincingly argues against weaknesses in Abelard's semantic theory by proposing a pragmatic approach.

A penetrating and historically important critique of medieval moral thought.

The most comprehensive compilation of the works of Abelard and Heloise ever presented in a single volume in English, _The Letters and Other Writings_ features an accurate and stylistically faithful new translation of both _The Calamities of Peter Abelard_ and the remarkable letters it sparked between the ill-fated twelfth-century philosopher and his brilliant former student and lover—an exchange whose intellectual passion, formal virtuosity, and psychological drama distinguish it as one of the most extraordinary correspondences in European history. Thanks to (...) this edition, Latin-less readers will be better placed than ever to see why this undisputed milestone in the intellectual life of medieval France is also a masterpiece of Western literature. In addition to the _The Calamities_ and the letters--the first complete English translation of all seven in more than eighty years--this volume includes an Introduction, a map, and a chronology, Abelard's _Confession of Faith_, letters between Heloise and Peter the Venerable, the Introduction to _The Questions of Heloise_, and selected songs and poems by Abelard, among them a previously untranslated shaped poem, Open Wide Your Eyes. Extracts of lost letters sometimes ascribed to Abelard and Heloise are given in appendixes. (shrink)
