John Baconthorpe (c.1290-1345/8) was the best-known of the Carmelite scholastics in the Middle Ages. This article is a brief study of his solution to the philosophical problem of how the soul may be wholly present in the human body and present whole and undivided in each part. Baconthorpe’s account is of great interest for a number of reasons. He takes issue with one of his fellow Carmelite masters, alerting us to diversity of opinion within that ‘school’. Furthermore, in using terminology (...) and illustrative analogies drawn from terminist logic and the mathematical sciences, Baconthorpe is an important witness to what has been described as the ‘mathematization’ of philosophy and theology in late medieval England. Finally, study of Baconthorpe’s texts provides further evidence of the emergence of the theme of extension in fourteenth-century thought in which we can discern the roots of modern philosophical debate.

Gerard of Bologna (d. 1317) was the first Carmelite master at the University of Paris in the Middle Ages. In Quaestio 6, article 1 of his incomplete Summa theologiae, Gerard discusses the issue of teaching and learning. During the course of his discussion he summarises his understanding of the process of cognition in human beings and he considers God, angels and human beings as teachers. Gerard insists on the necessity of the teacher-student relationship in the handing on of human knowledge.

BackgroundInvolvement of adolescent girls in biomedical HIV research is essential to better understand efficacy and safety of new prevention interventions in this key population at high risk of HIV infection. However, there are many ethical issues to consider prior to engaging them in pivotal biomedical research. In Uganda, 16–17-year-old adolescents can access sexual and reproductive health services including for HIV or other sexually transmitted infections, contraception, and antenatal care without parental consent. In contrast, participation in HIV prevention research involving investigational (...) new drugs requires adolescents to have parental or guardian consent. Thus, privacy and confidentiality concerns may deter adolescent participation. We describe community perspectives on ethical considerations for involving adolescent girls in the MTN 034 study in Uganda.MethodsFrom August 2017 to March 2018, we held five stakeholder engagement meetings in preparation for the MTN 034 study in Kampala, Uganda (NCT03593655): two with 140 community representatives, two with 125 adolescents, and one with 50 adolescents and parents. Discussions were moderated by the study team. Proceedings were documented by notetakers. Summary notes described community perspectives of adolescent participation in HIV research including convergent, divergent or minority views, challenges, and proposed solutions.ResultsMost community members perceived parental or guardian consent as a principal barrier to study participation due to concerns about adolescent disclosure of pre-marital sex, which is a cultural taboo. Of 125 adolescent participants, 119 (95%) feared inadvertent disclosure of sexual activity to their parents. Community stakeholders identified the following critical considerations for ethical involvement of adolescents in HIV biomedical research: (1) involving key stakeholders in recruitment, (2) ensuring confidentiality of sensitive information about adolescent sexual activity, (3) informing adolescents about information to be disclosed to parents or guardians, (4) offering youth friendly services by appropriately trained staff, and (5) partnering with community youth organizations to maximize recruitment and retention.ConclusionsStakeholder engagement with diverse community representatives prior to conducting adolescent HIV prevention research is critical to collectively shaping the research agenda, successfully recruiting and retaining adolescents in HIV clinical trials and identifying practical strategies to ensure high ethical standards during trial implementation.

Reasoning about situations we take to be impossible is useful for a variety of theoretical purposes. Furthermore, using a device of impossible worlds when reasoning about the impossible is useful in the same sorts of ways that the device of possible worlds is useful when reasoning about the possible. This paper discusses some of the uses of impossible worlds and argues that commitment to them can and should be had without great metaphysical or logical cost. The paper then provides an (...) account of reasoning with impossible worlds, by treating such reasoning as reasoning employing counterpossible conditionals, and provides a semantics for the proposed treatment.

Creationism about fictional entities requires a principle connecting what fictions say exist with which fictional entities really exist. The most natural way of spelling out such a principle yields inconsistent verdicts about how many fictional entities are generated by certain inconsistent fictions. Avoiding inconsistency without compromising the attractions of creationism will not be easy.

Impossible fictions are valuable evidence both for a theory of fiction and for theories of meaning, mind and epistemology. This article focuses on what we can learn about fiction from reflecting on impossible fictions. First, different kinds of impossible fiction are considered, and the question of how much fiction is impossible is addressed. What impossible fiction contributes to our understanding of "truth in fiction" and the logic of fiction will be examined. Finally, our understanding of unreliable narrators and unreliable narration (...) in fiction needs to accommodate stories that, on the face of it, cannot possibly be true. (shrink)

In this paper, I motivate the view that quantitative parsimony is a theoretical virtue: that is, we should be concerned not only to minimize the number of kinds of entities postulated by our theories (i. e. maximize qualitative parsimony), but we should also minimize the number of entities postulated which fall under those kinds. In order to motivate this view, I consider two cases from the history of science: the postulation of the neutrino and the proposal of Avogadro's hypothesis. I (...) also consider two issues concerning how a principle of quantitative parsimony should be framed. (shrink)

Fourteen newly commissioned essays trace the historical development of the distinction between primary and secondary qualities, which lies at the intersection of issues in metaphysics, epistemology, and philosophy of perception. 'Primary and Secondary Qualities' focuses on the age of the Scientific Revolution, the 'locus classicus' of the distinction, but begins with chapters on ancient Greek and Scholastic accounts of qualities in an effort to identify its origins. The remainder of the volume is devoted to philosophical reflections on qualities from the (...) seventeenth century to the present day. Virtualliy every major figure is represented from Gassendi to Kant, and special attention is paid to Locke, Descartes, and Hume. The essays collected here cover a wide range of topics, including the foundation for the distinction, the question of whether it is lmetaphysical or merely epistemic, the status of secondary qualities, the nature of sensoriy representation, the relation between philosophy and science, the status of dispositions, and the semantics of sensible-quality terms"--Publisher's description, p.

Philosophers have found postulating possible worlds to be very useful in a number of areas, including philosophy of language and mind, logic, and metaphysics. Impossible worlds are a natural extension to this use of possible worlds, and can help resolve a number of difficulties thrown up by possible‐worlds frameworks.

When charitable matching occurs, both the person initially offering the matching donation and the person taking up the offer may well feel they have done something better than if they had donated on their own without matching. They may well feel they deserve some credit for the matched donation as well as their own. Can they both be right? Natural assumptions about charitable matching lead to puzzles that are challenging to resolve in a satisfactory way.

It is almost universally believed that some infinite regresses are vicious, and also almost universally believed that some are benign. In this paper I argue that regresses can be vicious for several different sorts of reasons. Furthermore, I claim that some intuitively vicious regresses do not suffer from any of the particular aetiologies that guarantee viciousness to regresses, but are nevertheless so on the basis of considerations of parsimony. The difference between some apparently benign and some apparently vicious regresses, then, (...) turns out to be a matter of a more general assessment of costs and benefits, making viciousness of regresses in some cases less of a local matter than is usually thought.

Possible worlds have found many applications in contemporary philosophy: from theories of possibility and necessity, to accounts of conditionals, to theories of mental and linguistic content, to understanding supervenience relationships, to theories of properties and propositions, among many other applications. Almost as soon as possible worlds started to be used in formal theories in logic, philosophy of language, philosophy of mind, metaphysics, and elsewhere, theorists started to wonder whether impossible worlds should be postulated as well. In many applications, possible worlds (...) face limitations that can be dealt with through postulating impossible worlds as well. This chapter examines some of the uses of impossible worlds, and philosophical challenges theories of impossible worlds face. (shrink)

Abstract Impossible fictions have lessons to teach us about linguistic representation, about mental content and concepts, and about uses of conceivability in epistemology. An adequate theory of impossible fictions may require theories of meaning that can distinguish between different impossibilities; a theory of conceptual truth that allows us to make useful sense of a variety of conceptual falsehoods; and a theory of our understanding of necessity and possibility that permits impossibilities to be conceived. After discussing these questions, strategies for resisting (...) the picture of impossible fictions presented here and in Part I are discussed. Perhaps apparently impossible fictions describe possibilities after all; or perhaps impossible fictions are all trivial; or perhaps some apparently intelligible impossible fictions are unintelligible after all.

This article focuses on the main methods used in analytic metaphysics. It first considers five important sources of constraints on metaphysical theorizing: linguistic and conceptual analysis, consulting intuitions, employing the findings of science, respecting folk opinion, and applying theoretical virtues in metaphysical theory choice such as preferring simpler theories, or preferring more explanatory theories. It then examines the role of formal methods in metaphysics as well as the role of metaphysical communities, traditions, and the place of the history of metaphysics (...) in contemporary work. It also discusses the issue of whether metaphysics should be seen as an enterprise that will yield knowledge of metaphysical matters or whether it should have more modest epistemic goals. Finally, it explores the question of how much of metaphysics is a priori. (shrink)

Marriages come in a very wide variety: if the reports of anthropologists and historians are to be believed, an extraordinarily wide variety. This includes some of the more unusual forms, including marriage to the dead; to the gods; and even to plants. This does suggest that few proposed marriage relationships would require 'redefining marriage': but on the other hand, it makes giving a general theory of marriage challenging. So one issue we should face is how accepting we should be of (...) the reports: to what extent reported 'marriages' really are marriages. This paper defends the view that almost all of these reported marriages are in fact marriages, and suggests some theoretical approaches that may be generous enough to account for this. (shrink)

What political problem can autobiography solve? This article examines the politics of Frederick Douglass’s antebellum personal narratives: his 1845 slave narrative, the Narrative of the Life of Frederick Douglass, an American Slave, and his 1855 autobiography, My Bondage and My Freedom, written at the opposite ends of Douglass’s transition from the abolitionist politics of William Lloyd Garrison and Wendell Phillips to Douglass’s defense of political action and the Constitution as anti-slavery. Placing the two texts alongside Douglass’s distinction “to narrate wrongs” (...) and “denouncing them,” I argue that Douglass writes My Bondage and My Freedom as a mode of denunciation: an autobiographical critique of injustice that balances analysis of collective oppression with advocacy for communal emancipation. Whereas to narrate wrongs encouraged readers to judge Douglass’s story alongside popular criteria of justice, to denounce wrongs is to implicate readers within the structures that create antebellum subjects on and off the plantation, by revealing the coercions and conditionings of society that make not simply slaves but slaveowners, sympathizers, and abolitionists. This article claims that autobiography is a distinct genre of political theory, one that challenges present relations between the individual and the collective by representing not simply its author but an expanded view of “the people.”.

Simone Weil (1909-1943) was a defining figure of the twentieth century; a philosopher, Christian, resistance fighter, anarchist, feminist, labor activist and teacher. She was described by T. S. Eliot as "a woman of genius, of a kind of genius akin to that of the saints," and by Albert Camus as "the only great spirit of our time." Originally published posthumously in two volumes, these newly reissued notebooks, are among the very few unedited personal writings of Weil's that still survive today. (...) Containing her thoughts on art, love, science, God and the meaning of life, they give context and meaning to Weil's famous works, revealing a unique philosophy in development and offering a rare private glimpse of her singular personality.

In lieu of an abstract, here is a brief excerpt of the content:Christ's Human Nature and the Cry from the Cross:St. Thomas Aquinas on Psalm 22:2Philip Nolan O.P.Christ's cry from the Cross quoting Psalm 22 (Mark 15:34; Matt 27:46) has become a central focus for contemporary Christological debates.1 A number of modern thinkers have read this verse as expressing in Christ an experience of dereliction incompatible with traditional positions concerning divine impassibility Christ's beatific knowledge, and Trinitarian relations.2 Thomas Joseph (...) White has recently offered an insightful Thomistic critique of these interpretations: [End Page 1219]The final cry of Christ on the cross cannot be interpreted as a cry of either despair or of spiritual separation from God. By contrast, it must be understood theologically as a prayer of desire related to Christ's abandonment to the Father and his hope to introduce humanity into the eschatological gift of redemption.3In his work, White is concerned to engage with modern Christological themes using principles derived from the Thomistic tradition. For this reason, he articulates a rather original alternative to modern theologies of dereliction—especially those marked by divine kenoticism and Luther's theology of the Cross. In offering a view inspired by Thomistic principles, White presents his own creative retrieval of Aquinas's ideas concerning the cry from the Cross.At times, however, White's argument leaves somewhat obscure the literal meaning of the words of that cry: "My God, my God, why have you abandoned me?"4 For example, in pushing back against radical interpretations [End Page 1220] of dereliction, he shifts the language of "abandonment" from God's abandonment of Christ to Christ's abandonment to the Father. My argument in this article is that the textual commentaries on Psalm 225 by Augustine and Aquinas—material that White does not consider specifically—can provide an alternate and somewhat complementary Thomistic approach to the one White proposes, and one more soundly based on Aquinas's texts themselves.6 Christ's cry is a quote from this psalm, and Aquinas's commentary on Ps 22:27 develops the Augustinian interpretation of this verse in order to give greater emphasis to Christ's human nature. This emphasis helps to explain, in a classical way, what it can mean that Christ is abandoned. Thus, Aquinas's exegesis bolsters the orthodox response to contemporary revisionist theologians by providing a clear literal understanding of this contested biblical passage without applying an experience of damnation to Christ or denying classical positions concerning divine impassibility, Christ's beatific knowledge, and the nature of Trinitarian relations.To make this argument, I will first look at the rich tradition of reflection on the Christological meaning of the Psalms, and Psalm 22 in particular, inherited by Thomas. This tradition includes a series of psalm commentaries, conciliar documents, and a variety of other theological works. In this tradition, I argue, we see two primary interpretative approaches. The first is what I will call the Augustinian approach, which insists that Christ is speaking on the Cross for sinners and in the voice of sinners. The second interpretation places more weight on Christ's own voice and insists that he is speaking in a real way for himself—Christ in some way truly is abandoned by God. These interpretations need not and should not be read as contradictory. In fact, all the authorities I examine insist on the first approach. Differences emerge, however, in how they coordinate the latter interpretation with the former. I will discuss Thomas's synthesis of these interpretations, a synthesis that he grounds in the reality of Christ's human nature. Finally, I will suggest [End Page 1221] how a close reading of Thomas's mature treatment of Ps 22:2 supplements contemporary Thomist responses to modern Christological concerns and misguided interpretations of Christ's cry on the Cross.Thomas's Sources for Reading Psalm 22:2Thomas's primary source for understanding Ps 22:2 is Scripture itself Both Mark and Matthew report that Christ spoke the words of this psalm from the Cross, a fact which necessitates for Thomas a Christological interpretation of the psalm.8 Augustine links Ps 22:2 with passages in...

The ontological pictures underpinning David Lewis's Parts of Classes and On the Plurality of Worlds are in some tension. One tension concerns whether the sets and classes of Parts of Classes can be found in Lewis's modal space, since they cannot in general be parts of any possible world. The second is that the atoms that are the mathematical ontology of Parts of Classes seem to meet the criteria for being possible worlds themselves, and so fail to be the material (...) Parts of Classes needs. Two different responses to these tensions are discussed: one is unappealing in several ways but keeps more of Lewis's doctrines, while the other requires some modifications to the system of Parts of Classes.

Particle indistinguishability has always been considered a purely quantum mechanical concept. In parallel, indistinguishable particles have been thought to be entities that are not properly speaking objects at all. I argue, to the contrary, that the concept can equally be applied to classical particles, and that in either case particles may (with certain exceptions) be counted as objects even though they are indistinguishable. The exceptions are elementary bosons (for example photons).

The relationship of part to whole is one of the most fundamental there is; this is the first and only full-length study of this concept. This book shows that mereology, the formal theory of part and whole, is essential to ontology.

We demonstrate that the quantum-mechanical description of composite physical systems of an arbitrary number of similar fermions in all their admissible states, mixed or pure, for all finite-dimensional Hilbert spaces, is not in conflict with Leibniz's Principle of the Identity of Indiscernibles (PII). We discern the fermions by means of physically meaningful, permutation-invariant categorical relations, i.e. relations independent of the quantum-mechanical probabilities. If, indeed, probabilistic relations are permitted as well, we argue that similar bosons can also be discerned in all (...) their admissible states; but their categorical discernibility turns out to be a state-dependent matter. In all demonstrated cases of discernibility, the fermions and the bosons are discerned (i) with only minimal assumptions on the interpretation of quantum mechanics; (ii) without appealing to metaphysical notions, such as Scotusian haecceitas, Lockean substrata, Postian transcendental individuality or Adamsian primitive thisness; and (iii) without revising the general framework of classical elementary predicate logic and standard set theory, thus without revising standard mathematics. This confutes: (a) the currently dominant view that, provided (i) and (ii), the quantum-mechanical description of such composite physical systems always conflicts with PII; and (b) that if PII can be saved at all, the only way to do it is by adopting one or other of the thick metaphysical notions mentioned above. Among the most general and influential arguments for the currently dominant view are those due to Schrodinger, Margenau, Cortes, Dalla Chiara, Di Francia, Redhead, French, Teller, Butterfield, Giuntini, Mittelstaedt, Castellani, Krause and Huggett. We review them succinctly and critically as well as related arguments by van Fraassen and Massimi. (shrink)

Despite its growing use over past decades, there has been relatively little public or scholarly discussion of life sentences that deny the possibility of parole. This essay outlines the labyrinthine legal and political developments that have rendered life imprisonment difficult to address—including the intertwined histories of the death penalty and civil death—and draws upon the life writing of those serving life to theorize a more distinct understanding of this punishment. Witnesses reveal how the possibility of life despite the impossibility of (...) parole punishes by subverting the goals of human growth and development. The potentiality of what can be done in the present grinds up against the futility of what could have been done and what could be done were release an option. Considered alongside the laws and court opinions and claims that characterize its convoluted development, these testimonies reveal this punishment’s role in the American imagination. Life without the possibility of parole reinforces and relies upon a vision that not simply some people are unable to change, but that anyone in a democracy—no matter their position—is some steps away from irretrievable exclusion. Permanent confinement denies a restorative vision of democracy: any effort to abolish or amend it must include the voices of those imprisoned. (shrink)

Gravity and Grace was the first ever publication by the remarkable thinker and activist, Simone Weil.

I show that frequentism, as an explanation of probability in classical statistical mechanics, can be extended in a natural way to a decoherent quantum history space, the analogue of a classical phase space. The result is a form of finite frequentism, in which Gibbs’ concept of an infinite ensemble of gases is replaced by the quantum state expressed as a superposition of a finite number of decohering microstates. It is a form of finite and actual frequentism (as opposed to hypothetical (...) frequentism) insofar as all the microstates exist, in keeping with the decoherence-based Everett interpretation, and some versions of pilot-wave theory.

David Lewis rejected consequentialism in ethics. However, two aspects of his meta-ethical views make it a challenge to see how consequentialism could be resisted. Lewis endorses a maximising conception of rationality, where to be rational is to maximise value of a certain sort; he appears to think it is possible to be both rational and moral; and yet he rejects conceptions of moral action as acting to maximise moral value. The second tension in Lewis's views arises from his meta-ethics. Lewis's (...) naturalisation of morality is in terms of a naturalised account of value, including moral value. Insofar as he offers a motivational story for moral judgements, it is one that goes via a motivational connection to value. Yet his anti-consequentialism seems to commit him to rejecting a story of moral action entirely in terms of pursuit of moral value. In both cases there are things to be said about how to weave these strands of Lewis's thought together. After setting out these two apparent tensions in Lewis's thought about ethics, the paper discusses what a Lewisian could best say about these puzzles. Lewisians do have a number of plausible options for dealing with the first challenge. While there are things a Lewisian could attempt to extend Lewis's moral naturalism in a way that could deal with the second challenge, it is harder to see how to do this in a satisfying way. Attention then turns to what Lewis said in his letters on these topics: on that basis, perhaps Lewis was close to being an agent-relative consequentialist after all. (shrink)

The central claim of this article is that post-truth requires a political and socio-economical perspective, rather than a moral or epistemological one. The article consists of two parts. The first part offers a critical examination of the dominant analyses of post-truth in terms of shifting standards of the origin and the evaluation of facts. Moreover, the claim that postmodernism is the cause of post-truth is examined and refuted. In the second part an alternative perspective is developed, centring around the notion (...) of gatekeepers. Rather than linking post-truth to bullshit and postmodernism, it should be understood as a symptom of a contemporary shift in the gatekeepers of truth and knowledge. Knowledge and truth are always mediated in society through the hands of gatekeeping institutions such as journalism or science. Post-truth is a symptom of a broader transformation of the gatekeeping institutions of our current society. It therefore requires a political philosophy of these institutional shifts and the new risks they involve. (shrink)

An overview of hyperintensionality is provided. Hyperintensional languages have expressions with meanings that are more fine-grained than necessary equivalence. That is, the expressions may necessarily co-apply and yet be distinct in meaning. Adequately accounting for theories cast in hyperintensional languages is important in the philosophy of language; the philosophy of mind; metaphysics; and elsewhere.

The cognition and information theoretic sciences have now been in existence for the better part of a century. In that time, their varied disciplines have undergone extensive maturation, honing their methods, constitutions, and evaluation techniques in the pursuit of academic rigor, while not losing sight of the practical influences that have served as their almost universal cornerstone. Meanwhile, this period has also been marked by increasing disparity and gradual distancing of the philosophical underpinnings upon which each field is founded, adding (...) strain to interdisciplinary collaborative efforts. This article presents an overview of select information-science-related cognition disciplines, and shows how the nascent Philosophy of Information can be adopted as a means of unifying these philosophical foundations in an empirically sound manner, without sacrificing general applicability. In addition, it demonstrates how PI is already rooted in the philosophies or epistemological views of several of the cognition disciplines, implicitly or otherwise. (shrink)
