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)

What's wrong with designer children, bionic athletes, and genetic engineering.

At the heart of ethics reside the concepts of good and bad; they are at work when we assess whether a person is virtuous or vicious, an act right or wrong, a decision defensible or indefensible, a goal desirable or undesirable. But there are many varieties of goodness and badness. At their core lie intrinsic goodness and badness, the sort of value that something has for its own sake. It is in virtue of intrinsic value that other types of value (...) may be understood, and hence that we can begin to come to terms with questions of virtue and vice, right and wrong, and so on. This book investigates the nature of intrinsic value: just what it is for something to be valuable for its own sake, just what sort of thing can have such value, just how such a value is to be computed. In the final chapter, the fruits of this investigation are applied to a discussion of pleasure, pain, and displeasure and also of moral virtue and vice, in order to determine just what value lies within these phenomena.

I defend (metaphysical) ground against recent, unanswered objections aiming to dismiss it from serious philosophical inquiry. Interest in ground stems from its role in the venerable metaphysical project of identifying which facts hold in virtue of others. Recent work on ground focuses on regimenting it. But many reject ground itself, seeing regimentation as yet another misguided attempt to regiment a bad idea (like phlogiston or astrology). I defend ground directly against objections that it is confused, incoherent, or fruitless. This vindicates (...) the very attempt to regiment ground. It also refocuses our attention on the genuine open questions about ground and away from the distracting, unpersuasive reasons for dismissing them. (shrink)

There is currently an explosion of interest in grounding. In this article we provide an overview of the debate so far. We begin by introducing the concept of grounding, before discussing several kinds of scepticism about the topic. We then identify a range of central questions in the theory of grounding and discuss competing answers to them that have emerged in the debate. We close by raising some questions that have been relatively neglected but which warrant further attention.

In this paper we discuss ethical implications of the use of mobile phone apps in the control of the COVID-19 pandemic. Contact tracing is a well-established feature of public health practice during infectious disease outbreaks and epidemics. However, the high proportion of pre-symptomatic transmission in COVID-19 means that standard contact tracing methods are too slow to stop the progression of infection through the population. To address this problem, many countries around the world have deployed or are developing mobile phone apps (...) capable of supporting instantaneous contact tracing. Informed by the on-going mapping of ‘proximity events’ these apps are intended both to inform public health policy and to provide alerts to individuals who have been in contact with a person with the infection. The proposed use of mobile phone data for ‘intelligent physical distancing’ in such contexts raises a number of important ethical questions. In our paper, we outline some ethical considerations that need to be addressed in any deployment of this kind of approach as part of a multidimensional public health response. We also, briefly, explore the implications for its use in future infectious disease outbreaks. (shrink)

Sceptical theists--e.g., William Alston and Michael Bergmann--have claimed that considerations concerning human cognitive limitations are alone sufficient to undermine evidential arguments from evil. We argue that, if the considerations deployed by sceptical theists are sufficient to undermine evidential arguments from evil, then those considerations are also sufficient to undermine inferences that play a crucial role in ordinary moral reasoning. If cogent, our argument suffices to discredit sceptical theist responses to evidential arguments from evil.

This paper raises a problem for the pair of views that universals are immanent in their instantiations and that these instantiations, or states of affairs, are somehow constructed from the instantiated universals. It is argued that the pair is inconsistent. The first view implies that universals are prior to states of affairs, whereas the second view implies that states of affairs are prior to universals. This paper does not attempt to solve this problem, but rather to formulate it precisely. That (...) promises to illuminate how to solve the problem if it can be solved, or why it cannot be solved if it is unsolvable. (shrink)

This paper contains a critical examination of the prospects for analyses of knowledge that weaken the factivity condition such that knowledge implies approximate truth.

If a man born blind were to gain his sight in later life would he be able to identify the objects he saw around him? Would he recognise a cube and a globe on the basis of his earlier tactile experiences alone? This was William Molyneux's famous question to John Locke and it was much discussed by English and French empiricists in the eighteenth century as part of the controversy over innatism and abstract ideas. Dr Morgan examines the whole history (...) of this debate: Locke's own (negative) answer to the question, the contributions of Berkeley, Condillac, Diderot and Voltaire and the factual accounts of early cataract operations and modern laboratory studies. He shows how this debate is involved in the development and eventual separation of philosophy and experimental psychology after the eighteenth century and considers why the original question is effectively still unanswered. This is one problem-area with its intricate cluster of connected conceptual and technical difficulties which suggests the need for some reunion or at least collaboration between the two subjects.

The coevolution of humans with their intestinal microflora has resulted in cooperative relationships that have shaped the biology and the genomes of these symbiotic partners. Bacteroides thetaiotaomicron is one such bacterial symbiont that is a dominant member of the intestinal microbiota of humans and other mammals. The recent report of the genome sequence of B. thetaiotaomicron1 is the first reported for an abundant Gram‐negative organism of the human colonic microbiota and, as such, provides the first glimpse on a genomic scale (...) of the genetic arsenal used by a Gram‐negative symbiont to dominate in this ecosystem. The genome has revealed large expansions of many paralogous groups of genes that encode products essential to the organism's ability to successfully compete in this environment. Most noteable is the organism's abundant machinery for utilizing a large variety of complex polysaccharides as a source of carbon and energy. The proteome also reveals the organism's extensive ability to adapt and regulate expression of its genes in response to the changing ecosystem. These factors, as well as others highlighted below, suggest an incredibly flexible and adaptable organism that is exquisitely equipped to dominate in its challenging and competitive niche.

Is logic out of this world? This elusive question reveals a tension in our thinking about the basis of logic: both worldly and unworldly answers get something right and yet they conflict. My aim is to clarify the question and explore a conciliatory answer. I focus on a characterization of unworldliness in terms of ground. This allows for a distinction between proximal and distal unworldliness. That in turn reconfigures our approach to the question. It may now be taken as asking (...) for the proximal or the distal basis of logic. This helps alleviate the tension because the answer for the one needn’t conflict with a different answer for the other. I explore a case study culminating in an illustration of how a logical truth may indeed be proximally worldly but distally unworldly. I conclude by considering some potential extensions. (shrink)

This article presents a critique of Philip Pettit’s concept of ‘freedom as non-domination’ and provides an alternative theory of both domination and republican political freedom. I argue that Pettit’s neo-republican concept of domination is insufficient to confront modern forms of domination and that this hampers his concept of republican freedom and its political relevance under the conditions of modernity. Whereas the neo-republican account of domination is defined by ‘arbitrary interference’, modern forms of domination, I argue, are characterized by routinization and (...) systemic forms of control and subordination. In the end, the neo-republican account of domination is more appropriate for 17th- and 18th-century social institutions rather than those that persist under modernity. In its place, I propose a more dynamic concept of domination and rework the concept of freedom in order to place the republican tradition within the context of modernity itself. I argue that the core insight of republicanism is its emphasis on the arrangement and reformation of social institutions to enhance social freedom. From this, I argue that republicanism can take its place as a more attractive alternative to liberal theory. (shrink)

This paper shows how the availability heuristic can be used to justify inference to the best explanation in such a way that van Fraassen's infamous "best of a bad lot" objection can be adroitly avoided. With this end in mind, a dynamic and contextual version of the erotetic model of explanation sufficient to ground this response is presented and defended.

High quality learning is extensive, well integrated, deep, and supports the use of knowledge in new situations that require adaptation of what has been learned previously. This book reviews current research on the nature of high quality learning and the factors that facilitate or inhibit it. The book addresses relationships between quality of learning and learners' dispositions, teaching methods, cognitive strategies, assessment and technologies that can support learning. The chapters provide theoretical analyses, reports of classroom research, and suggestions for practical (...) application for both teachers and learners. The book will be of value to teachers at all levels of education and provides guidance for students about how to approach classroom tasks in order to develop high quality learning. (shrink)

In this paper significant challenges are raised with respect to the view that explanation essentially involves unification. These objections are raised specifically with respect to the well-known versions of unificationism developed and defended by Michael Friedman and Philip Kitcher. The objections involve the explanatory regress argument and the concepts of reduction and scientific understanding. Essentially, the contention made here is that these versions of unificationism wrongly assume that reduction secures understanding.

The debate over corporate moral responsibility has become a fixture in business ethics research and teaching. Only rarely, however, does the sizable literature on that question consider whether the debate has important practical implications. This article examines that question from a corporate control perspective. After assuming corporate moral responsibility’s existence for purposes of argument, the article concludes that such responsibility makes a difference in cases where it is present but personal responsibility is absent. Then the article tries to identify the (...) forces that diminish personal responsibility when corporate responsibility exists. The most important such forces, it concludes, spring from the socialization processes people undergo when they enter groups. One example is the well-known phenomenon of groupthink, which can exculpate individuals by rendering them justifiably ignorant of foreseeable risks of harm. (shrink)

The fitting-attitudes analysis of value, which states that something's being good consists in its being the fitting object of some pro-attitude, has recently been the focus of intense debate. Many objections have been levelled against this analysis. One objection to it concerns the ‘challenge from partiality’, according to which it can be fitting to display partiality toward objects of equal value. Several responses to the challenge have been proposed. This paper criticizes these and other responses and then offers a response (...) that, it is claimed, solves the challenge. (shrink)

For nearly two centuries, developmental biologists have known that body organs are derived from distinct germ layers. They have argued that adult stem cells formed in one of these, mesoderm for example, cannot give rise to cells that originate in another. We disagree. An exception to this “rule” has been described in crayfish recently. In this species, hemocytes appear to replenish neurogenic cells. This may happen in humans as well. In women who were given male bone marrow‐derived cells, Y chromosome (...) positive cheek cells and brain neurons were detected. While repopulation of these tissues by bone marrow derived cells may not occur normally, and while it does not appear to be terribly efficient, the phenomenon should be studied in more detail. Perhaps cells in the marrow could be used to regenerate tissues elsewhere. (shrink)

Van Fraassen’s (1989) infamous best of a bad lot objection is widely taken to be the most serious problem that afflicts theories of inference to the best explanation (IBE), for it alleges to show that we should not accept the conclusion of any case of such reasoning as it actually proceeds. Moreover, this is supposed to be the case irrespective of the details of the particular criteria used to select best explanations. The best of a bad lot objection is predicated (...) on, and really only requires, the idea that in any real case of IBE where one hypothesis is favored as best over those with which it competes, it is always the case that it is more likely that the true explanation is to be found in the set of unformulated and unconsidered logical alternatives to the set of actually considered hypotheses. On this basis, Van Fraassen believes that accepting the conclusion of IBEs so understood is irrational and this is simply because such inferences are supposedly not probative. In this paper the best of a bad lot objection will be addressed and it will be shown that Van Fraassen’s notorious criticism of IBE depends on a problematic conflation of two notions of rationality and thus that his criticism of IBE involves a damning equivocation. In essence, he conflates ideal standards of rationality with epistemic standards of rationality and, in so doing, makes it appear to be the case that we should not accept the conclusions of IBEs. But, when we disambiguate the concepts of rationality at work in the argument Van Fraassen’s conclusion simply does not follow. (shrink)

According to vitalism, living organisms differ from machines and all other inanimate objects by being endowed with an indwelling immaterial directive agency, ‘vital force,’ or entelechy . While support for vitalism fell away in the late nineteenth century many biologists in the early twentieth century embraced a non vitalist philosophy variously termed organicism/holism/emergentism which aimed at replacing the actions of an immaterial spirit with what was seen as an equivalent but perfectly natural agency—the emergent autonomous activity of the whole organism. (...) Organicists hold that organisms unlike machines are ‘more than the sum of their parts’ and predict that the vital properties of living things can never be explained in terms of mechanical analogies and that the reductionist agenda is doomed to failure. Here we review the current status of the mechanist and organicist conceptions of life particularly as they apply to the cell. We argue that despite the advances in biological knowledge over the past six decades since the molecular biological revolution, especially in the fields of genetics and cell biology the unique properties of living cells have still not been simulated in mechanical systems nor yielded to reductionist—analytical explanations. And we conclude that despite the dominance of the mechanistic–reductionist paradigm through most of the past century the possibility of a twentyfirst century organicist revival cannot be easily discounted.

Recently a number of variously motivated epistemologists have argued that knowledge is closely tied to practical matters. On the one hand, radical pragmatic encroachment is the view that facts about whether an agent has knowledge depend on practical factors and this is coupled to the view that there is an important connection between knowledge and action. On the other hand, one can argue for the less radical thesis only that there is an important connection between knowledge and practical reasoning. So, (...) defenders of both of these views endorse the view that knowledge is the norm of practical reasoning. This thesis has recently come under heavy fire and a number of weaker proposals have been defended. In this paper counter-examples to the knowledge norm of reasoning will be presented and it will be argued that this viewand a number of related but weaker viewscannot be sustained in the face of these counter-examples. The paper concludes with a novel proposal concerning the norm of practical reasoning that is immune to the counter-examples introduced here. (shrink)

What does one do as a Jewish philosopher if one is convinced by much of the Nietzschean critique of religion? Is there a contemporary Jewish philosophical theology that can convince in a post-metaphysical age? The argument of this book is that Rabbi Joseph Soloveitchik - the leading twentieth-century exponent of Modern Orthodoxy - presents an interpretation of halakhic Judaism, grounded in traditional sources, that brings a life-affirming Nietzschean sensibility to the religious life. Soloveitchik develops a form of Judaism replete with (...) key Nietzschean ideas, which parries Nietzsche's critique by partially absorbing it. This original study of Soloveitchik's philosophy highlights his unique contribution to Jewish thought for students and scholars in Jewish studies, while also revealing his wider significance for those working more broadly in fields such as philosophy and religious studies.

This article argues that the dynamics behind the generation of social pathologies in modern society also undermine the social-relational framework for recognition. It therefore claims that the theory of recognition is impotent in face of the kinds of normative power exerted by social hierarchies. The article begins by discussing the particular forms of social pathology and their relation to hierarchical forms of social structure that are based on domination, control and subordination and then shows how the internalization of the norms (...) that shape and hold together hierarchical social formations causes pathologies within the self. As a result of these processes, the recognitive aspects of social action that the theory of recognition posits are unable to overcome and in fact reproduce and in many instances reinforce the pathologies themselves.

Consider the following situation. It is the first day of school, and the new third-grade students file into the classroom to be shown to their seats for the coming year. As they enter, the third-grade teacher notices one small boy who is particularly unkempt. He looks to be in desperate need of bathing, and his clothes are dirty, torn and tight-fitting. During recess, the teacher pulls aside the boy's previous teacher and asks about his wretched condition. The other teacher informs (...) her that he always looks that way, even though the boy's family is quite wealthy. The reason he appears as he does, she continues, is that the family observes an odd practice according to which the children do not receive many important things – food, clothing, bathing, even shelter – unless they specifically request them. Since the boy, like many third-graders, has little interest in bathing and clean clothes, he just never asks for them. (shrink)

Forrester’s proposed seventh style of reasoning – thinking in cases – functions as an analogous, dyadic relationship that, whilst indebted philosophically to the logical reasoning and semiotics of Charles Peirce, is prone to creating feedback loops between induction and deduction, precluding novel abductive hypotheses from advancing medical knowledge. Reasoning with a Peircean triadic model opens up the contexts and methods of meaning-making and reasoning through medical cases, and the potent influence of their genre conventions, to intellectual critical scrutiny. Vitally, it (...) offers a third mode – abduction – that this article argues needs to be reintroduced into Forrester’s model of reasoning with cases. This article demonstrates this by applying a Peircean triadic model of reasoning to Forrester’s own model, tracing a shared genealogy but one in which the abductive element was lost. The article goes on to illustrate the explanatory and predictive potential of Peircean abductive reasoning and the necessary re-theorising of the case this entails. This argument is supported through an analysis of early case reports of what would become HIV/Aids, drawn from the Case Records of Massachusetts General Hospital series in the New England Journal of Medicine.

A key takeaway from the recent volume Theistic Evolution: A Scientific, Philosophical, and Theological Critique is that no version of theistic evolution that adheres largely to consensus views in biology is a plausible option for orthodox Christians. In this paper we argue that this is false: contrary to the arguments in the volume, evolutionary theory, properly understood, is perfectly compatible with traditional Christian commitments. In addition, we argue that the lines between Intelligent Design and theistic evolution are not as sharp (...) as most scholars have assumed, such that many who self-identify as Intelligent Design adherents would also qualify as theistic evolutionists.

Some carnivores defend the position that the opportunistic consumption of meat is morally permissible even under the assumption that it is morally wrong to act in ways that ause unnecessary suffering to sentient beings. Ordering and consuming chicken once a week, they argue, will not increase the numbers of chickens suffering or slaughtered, since the system of purchasing and farming chickens is not sufficiently fine‐tuned to register differences at margin. We argue that, insensitivity of the market notwithstanding, consistent consequentialists are (...) morally prohibited from each additional purchase and consumption of meat. (shrink)

In this paper Timothy Williamson’s argument that the knowledge norm of assertion is the best explanation of the unassertability of Morrean sentences is challenged and an alternative account of the norm of assertion is defended.

How do we and should we decide what is morally right and what is morally wrong? For much of human history, the teachings of religion were presumed to provide either the answer, or much of the answer. Over time, two developments challenged this. The first was the establishment of the discipline of moral philosophy. Foundational texts, such as Immanuel Kant's Groundwork of the Metaphysics of Morals, and the growth of coherent, nonreligious approaches to ethics, notably utilitarianism, served to marginalize the (...) role of religion. And then, second, the twentieth century saw the rapid growth of evolutionary biology with an enthusiastic presumption that biology was the source of ethics. Here, I begin by discussing these developments and then examine the extent to which religion is still needed for a coherent account of ethics. (shrink)

Defenders of doxastic voluntarism accept that we can voluntarily commit ourselves to propositions, including belief-contravening propositions. Thus, defenders of doxastic voluntarism allow that we can choose to believe propositions that are negatively implicated by our evidence. In this paper it is argued that the conjunction of epistemic deontology and doxastic voluntarism as it applies to ordinary cases of belief-contravening propositional commitments is incompatible with evidentialism. In this paper ED and DV will be assumed and this negative result will be used (...) to suggest that voluntary belief-contravening commitments are not themselves beliefs and that these sorts of commitments are not governed by evidentialism. So, the apparent incompatibility of the package views noted above can be resolved without ceding evidentialism with respect to beliefs. (shrink)

David hume is sometimes viewed as a skeptic who argues that none of our beliefs about the world are justified. this paper challenges that view by developing and explicating an account of justified belief that is compatible with hume's theories about belief formation, inference, and principles governing the association of ideas. it is noted that the resultant account bears some resemblance to contemporary causal/reliability views of justification.

Paradoxes have played an important role both in philosophy and in mathematics and paradox resolution is an important topic in both fields. Paradox resolution is deeply important because if such resolution cannot be achieved, we are threatened with the charge of debilitating irrationality. This is supposed to be the case for the following reason. Paradoxes consist of jointly contradictory sets of statements that are individually plausible or believable. These facts about paradoxes then give rise to a deeply troubling epistemic problem. (...) Specifically, if one believes all of the constitutive propositions that make up a paradox, then one is apparently committed to belief in every proposition. This is the result of the principle of classical logical known as ex contradictione (sequitur) quodlibetthat anything and everything follows from a contradiction, and the plausible idea that belief is closed under logical or material implication (i.e. the epistemic closure principle). But, it is manifestly and profoundly irrational to believe every proposition and so the presence of even one contradiction in one’s doxa appears to result in what seems to be total irrationality. This problem is the problem of paradox-induced explosion. In this paper it will be argued that in many cases this problem can plausibly be avoided in a purely epistemic manner, without having either to resort to non-classical logics for belief (e.g. paraconsistent logics) or to the denial of the standard closure principle for beliefs. The manner in which this result can be achieved depends on drawing an important distinction between the propositional attitude of belief and the weaker attitude of acceptance such that paradox constituting propositions are accepted but not believed. Paradox-induced explosion is then avoided by noting that while belief may well be closed under material implication or even under logical implication, these sorts of weaker commitments are not subject to closure principles of those sorts. So, this possibility provides us with a less radical way to deal with the existence of paradoxes and it preserves the idea that intelligent agents can actually entertain paradoxes. (shrink)

This article is an explication and defense of Kant’s view that ‘imagination is a necessary ingredient of perception itself’ (Critique of Pure Reason, A120, fn.). Imagination comes into perception at a far more basic level than Strawson allows, and it is required for the constitution of intuitions (= sense experiences) out of sense impressions. It also plays an important part in explaining how it is possible for intuitions to have intentional contents. These functions do not involve the application of contents, (...) and I offer a schematic account of how they arise from preconceptual synthesis. (shrink)
