Cet article pointe certains rapprochements entre la pensée d’Emmanuel Levinas et celle de Svetlana Alexievitch, à qui fut décerné le prix Nobel de littérature en 2015, et tout particulièrement à mettre au jour leur hostilité à l’histoire entendue comme histoire officielle des vainqueurs et la « résistance éthique », au sens que Levinas donne à cette expression, c’est-à-dire à l’immense difficulté pour un être humain d’en tuer un autre, quelles que soient les conditions dans lesquelles s’effectue cet acte.

Data increasingly drive our lives. Often presented as a new trajectory, the deep immersion of our lives in data has a history that is well over a century old. By revisiting the work of early pioneers of what would today be called data science, we can bring into view both assumptions that fund our data-driven moment as well as alternative relations to data. I here excavate insights by contrasting a seemingly unlikely pair of early data technologists, Francis Galton and W.E.B. (...) Du Bois. Galton, well known for his contributions to eugenics, was first and foremost a tinkering technician of measure. There are numerous domains of science over which Galtonian conceptions retain considerable influence, presumably without his pride in racial inequality. A more viable, because more egalitarian, alternative for the present can be found in the early data work of Du Bois. (shrink)

This chapter analyzes several key themes in Kant’s views about modality. We begin with the pre-critical Only Possible Argument in Support of a Demonstration of the Existence of God, in which Kant distinguishes between formal and material elements of possibility, claims that all possibility requires an actual ground, and argues for the existence of a single necessary being. We then briefly consider how Kant’s views change in his mature period, especially concerning the role of form and thought in defining modality. (...) Kant’s mature views, however, present two difficult interpretive puzzles. The first puzzle concerns whether Kant has a generally reductive view of modality. While Kant’s views on logical modality, the role of actuality in grounding possibility, and the relation of modality to cognition all suggest reduction, we argue that the categorial status of modal concepts and the difficulty in even identifying amodal grounds for modal facts all suggest a non-reductive view. The second puzzle concerns whether Kant accepts modal facts or properties at the noumenal level. While Kant’s appeal to noumenal necessary connections, the contingency of noumenal willing, and the idea of a necessary noumenal being suggest that he endorses noumenal modality, his claims that modal concepts express only relations to the faculty of cognition and his claim that modal concepts arise from our distinctive psychological structures, we argue, suggest that he rejects noumenal modality. We conclude by considering potential solutions to these puzzles. (shrink)

In recent years there has been a resurgence of interest in the work of Emmanuel Levinas, widely recognized as one of the most important yet difficult philosophers of the 20th century. In this much-needed introduction, Davis unpacks the concepts at the centre of Levinas's thought - alterity, the Other, the Face, infinity - concepts which have previously presented readers with major problems of interpretation. Davis traces the development of Levinas's thought over six decades, describing the context in which he worked, (...) and the impact of his writings. He argues that Levinas's work remains tied to the ontological tradition with which he wants to break, and demonstrates how his later writing tries to overcome this dependency by its increasingly disruptive, sometimes opaque, textual practice. He discusses Levinas's theological writings and his relationship to Judaism, as well as the reception of his work by contemporary thinkers, arguing that the influence of his work has led to a growing interest in ethical issues among poststructuralist and postmodernist thinkers in recent years. Comprehensive and clearly written, this book will be essential reading for students and researchers in continental philosophy, French studies, literary theory and theology. (shrink)

Despite widespread recognition of an emergent politics of data in our midst, we strikingly lack a political theory of data. We readily acknowledge the presence of data across our political lives, but we often do not know how to conceptualize the politics of all those data points—the forms of power they constitute and the kinds of political subjects they implicate. Recent work in numerous academic disciplines is evidence of the first steps toward a political theory of data. This article maps (...) some limits of this emergent literature with an eye to enriching its theoretical range. The literature on data politics, both within political theory and elsewhere, has thus far focused almost exclusively on the algorithm. This article locates a further dimension of data politics in the work of formatting technology or, more simply, formats. Formats are simultaneously conceptual and technical in the ways they define what can even count as data, and by extension who can count as data and how they can count. A focus on formats is of theoretical value because it provides a bridge between work on the conceptual contours of categories and the technology-centric literature on algorithms that tends to ignore the more conceptual dimensions of data technology. The political insight enabled by format theory is shown in the context of an extended interrogation of the politics of racialized redlining. (shrink)

A variety of interpreters have argued that Kant construes the animality of human beings as ‘transformed’, in some sense, through the possession of rationality. I argue that this interpretation admits of multiple readings and that it is either wrong, or doesn't result in the conclusion for which its proponents argue. I also explain the sense in which rationality nevertheless significantly differentiates human beings from other animals.

George Berkeley's two major works, A Treatise Concerning the Principles of Human Knowledge and Three Dialogues Between Hylas and Philonous, are presented here, together with perhaps the most searching examination his ideas received during his lifetime, that of the American Samuel Johnson, who corresponded with Berkeley during his stay in the country.

In the last decade it has become en vogue for cognitive comparative psychologists to study animal behavior in an ‘integrated’ fashion to account for both the ‘innate’ and the ‘acquired’. We will argue that these studies, instead of really integrating the concepts of ‘nature’ and ‘nurture’, rather cement this old dichotomy. They combine empty nativist interpretation of behavior systems with blatantly environmentalist explanations of learning. We identify the main culprit as the failure to take development seriously. While in some areas (...) of biology interest in the relationship between behavior and development has surged through topics such as extragenetic inheritance, niche construction, and phenotypic plasticity, this has gone almost completely unnoticed in the study of animal behavior in comparative psychology, and is frequently ignored in ethology too. The main aims of this paper are to clarify the relationship between the concepts of learning, experience, and development, and to investigate whether and how all three concepts can be usefully deployed in the study of animal behavior. This will require the full integration of the psychological study of behavior into biology, and of the idea of learning into a wider concept of experience. We lay out how, in a systems view of development, learning may just appear as one among many processes in which experience influences behavior. This new synthesis should help to overcome the age-old dualism between innate and acquired. It thereby opens up the possibility of developing scientifically more fruitful distinctions. (shrink)

Henry More argues that materialism cannot account for cases where a single subject or perceiver has multiple perceptions simultaneously. Since we clearly do have multiple perceptions at the same time--for example, when we see, hear, and smell simultaneously--More concludes that we are not wholly material. In response to More's argument, Margaret Cavendish adopts a two-fold strategy. First, she argues that there is no general obstacle to mental unification in her version of materialism. Second, Cavendish appeals to the mind or rational (...) matter--terms she often uses interchangeably—to explain the integration of sensory input from multiple senses. When the mind integrates perceptions across modalities, the different parts of rational matter share their knowledge so that they all come to perceive alike. When rational parts successfully communicate their knowledge, each part knows what all the others know. They pool their knowledge; they perceive alike. Thus, when someone hears, sees, and tastes, each part of her mind hears, sees, and tastes alike, in parallel and in unison. The Cavendishian mind, in short, approximates simplicity by achieving uniformity or homogeneity of perceptions across its parts. (shrink)

I argue that Spinoza is more of a moral realist than an anti-realist. More specifically, I argue that Spinoza is more of a realist than Kant, and that his view has deep similarities with Plato's metaethics. Along the way, I identify three approaches to the moral realism/anti-realism distinction. Classifying Spinoza as a moral realist brings out a number of important complexities that have been overlooked by many of Spinoza's readers and by many contemporary metaethicists.

In one of his arguments for taking compassion to be the basis of morality, Schopenhauer offers a thought experiment involving two characters: Titus and Caius. The 'Titus Argument,' as I call it, has been misunderstood by many of Schopenhauer's readers, but is, I argue, worthy of attention by contemporary ethicists and metaethicists. In this chapter, I clarify the argument's structure, methodology, and its key philosophical move, drawing comparisons with Newton's experimental methodology in optics and Raimond Gaita's moral parodies.

Imagination and idealism are particularly important creative epistemic virtues for the medical sciences if we hope to improve the health of the world’s ageing population. To date, imagination and idealism within the medical sciences have been dominated by a paradigm of disease control, a paradigm which has realised significant, but also limited, success. Disease control proved particularly successful in mitigating the early-life mortality risks from infectious diseases, but it has proved less successful when applied to the chronic diseases of late (...) life (like cancer). The time is ripe for the emergence and prominence of a supplementary medical research paradigm, the paradigm of ‘healthy ageing’ which prioritises the goal of rate (of ageing) control rather than disease control. This is the difference between extending the human healthspan versus extending survival by managing (or trying to eliminate) the multi-morbidities, frailty and disability currently prevalent in late life. The idealism of the disease control paradigm is myopic because it ignores the health constraints imposed by the inborn ageing process itself, a biological reality which is already inflicting significant economic and disease burdens on the world’s ageing populations. Unless the medical sciences retard the rate of biological ageing, these problems will continue to be amplified as larger numbers of persons survive into late life. (shrink)

Elementary axioms describe a category of categories. Theorems of category theory follow, including some on adjunctions and triples. A new result is that associativity of composition in categories follows from cartesian closedness of the category of categories. The axioms plus an axiom of infinity are consistent iff the axioms for a well-pointed topos with separation axiom and natural numbers are. The theory is not finitely axiomatizable. Each axiom is independent of the others. Further independence and definability results are proved. Relations (...) between categories and sets, the latter defined as discrete categories, are described, and applications to foundations are discussed. (shrink)

Although dignity figures prominently in modern ethical discourse, and in the writings of moral and political philosophers writing today, we still lack a clear account of how the concept of dignity might be implicated in various forms of moral reasoning. This essay tries to make progress on two fronts. First, it attempts to clarify the possible roles the concept of dignity might play in moral discourse, with particular reference to Hart's distinction between positive and critical morality. Second, it offers a (...) new typology of dignity concepts and mobilizes it to, on the one hand, criticize some familiar construals of and, on the other, to advertise the possible virtues of an unfamiliar way of thinking about dignity as a moral concept.

Ralph Dahrendorf survived incarceration in a German concentration camp in 1944. He later took degrees in sociology at Hamburg University and the London School of Economics and spent some time as one of Germany's European Commissioners, although he was critical of aspects of the bureaucracy. Dahrendorf was Director of the London School of Economics for ten years and gave the Reith Lectures in 1974. He was elected a Fellow of the British Academy in 1977, knighted in 1982 and became Member (...) of the House of Lords in 1993. Dahrendorf retired to Germany. Obituary by Colin Crouch FBA. (shrink)

The social media platform Twitter platform has played a crucial role in the Black Lives Matter (BLM) movement. The immediate, flexible nature of tweets plays a crucial role both in spreading information about the movement’s aims and in organizing individual protests. Twitter has also played an important role in the right-wing reaction to BLM, providing a means to reframe and recontextualize activists’ claims in a more sinister light. The ability to bring about social change depends on the balance of these (...) two forces, and in particular which side can capture and maintain sustained attention. The present study examines 2 years worth of tweets about BLM (about 118 million in total). Timeseries analysis reveals that activists are better at mobilizing rapid attention, whereas right-wing accounts show a pattern of moderate but more sustained activity driven by reaction to political opponents. Topic modeling reveals differences in how different political groups talk about BLM. Most notably, the murder of George Floyd appears to have solidified a right-wing counter-framing of protests as arising from dangerous “terrorist” actors. The study thus sheds light on the complex network and rhetorical effects that drive the struggle for online attention to the BLM movement. (shrink)

The epistemic position of an agent often depends on their position in a larger network of other agents who provide them with information. In general, agents are better off if they have diverse and independent sources. Sullivan et al. [19] developed a method for quantitatively characterizing the epistemic position of individuals in a network that takes into account both diversity and independence; and presented a proof-of-concept, closed-source implementation on a small graph derived from Twitter data [19]. This paper reports on (...) an open-source reimplementation of their algorithm in Python, optimized to be usable on much larger networks. In addition to the algorithm and package, we also show the ability to scale up our package to large synthetic social network graph profiling, and finally demonstrate its utility in analyzing real-world empirical evidence of ‘echo chambers’ on online social media, as well as evidence of interdisciplinary diversity in an academic communications network.

By an argument form I shall mean a schema consisting of a string of symbols that are place-­‐holders for either logical terms or non-­‐logical (descriptive/content) terms: substituting terms of the appropriate kind for the symbols yields an argument. A substitution instance of an argument form is an argument that arises as a result of such a substitution. By a valid argument I shall mean an argument such that it is impossible for the premises to be true and the conclusion false. (...) Thus, an invalid argument is an argument such that it is possible for the premises to be true and the conclusion false. (shrink)

Despite his reputation for neglecting the body, Descartes develops a systematic account of bodily awareness. He holds that in bodily awareness each of us feels intimately connected to our body. We experience this body as inescapable, as infused with bodily sensations and volitions, and as a special object of concern. This multifaceted experience plays an ambivalent role in Descartes’s philosophy. Bodily awareness is epistemically dangerous. It tempts us to falsely judge that we cannot exist apart from our bodies. But bodily (...) awareness isn’t all bad for Descartes. It helps us stay alive. Bodily awareness also serves as a corrective to overly disembodied conceptions of the self. (shrink)

In his Epistemic Justification , Swinburne offers a sophisticated and intuitively plausible causal-doxastic analysis of the basing relation that has escaped the attention of those working on this relation, where the basing relation can be understood as the relation that holds between a reason and one’s belief when the belief is held for that reason. In this paper, I aim to fill this lacuna in the literature by arguing that, despite its initial plausibility, Swinburne’s analysis of the basing relation is (...) subject to a simple counterexample and so must be rejected.

Keith DeRose believes that it is a strength of his contextualist analysis that it explains why the recently much-discussed skeptical Argument from Ignorance (AI) is so persuasive. Not only that, however; DeRose also believes that he is able to explain the underlying dynamics of AI by utilizing solely the epistemological and linguistic resources contained within his contextualist analysis. DeRose believes, in other words, that his contextualist analysis functions as a genuinely self-contained explanation of skepticism. But does it? In this paper (...) I argue that DeRose’s analysis does not function as a self-contained explanation of skepticism since, as it turns out, DeRose’s analysis is simply irrelevant to the main concerns of the skeptic. To the extent that DeRose’s analysis is irrelevant in this way, I conclude that such an analysis cannot be considered a satisfactory treatment of AI. (shrink)

In the second chapter of his Modality, Probability and Rationality, James Sennett argues that Plantinga’s famed S5 Modal Argument (hereafter “MA”) for the existence of an unsurpassably great being is objectionably circular since it’s impossible for one to understand the premises of Plantinga’s MA without understanding these premises to logically entail its conclusion. That is to say, Sennett’s charge is that Plantinga’s MA is circular since there is no understanding of the premises of Plantinga’s MA that is independent of its (...) conclusion. In this paper I argue that Sennett has shown no such thing and that, contrary to strong prima facie appearances, there is an understanding of the premises of Plantinga’s MA that is independent of its conclusion. Consequently, Plantinga’s MA is not circular inthe way that Sennett alleges. (shrink)

This article examines the relationship between online dispute resolution (ODR) and trust. We discuss what trust is, why trust is important, and how trust develops. Our claim is that efforts to implement online dispute resolution on a site or service in a manner that promotes trust need to consider ODR as just one tool in a broader toolbox of trust-building tools and techniques. These techniques are amongst others marketing, education, trust seals, and transparency. By evaluating ODR in its proper context (...) as one component of a larger trust strategy, we can more accurately set expectations for its results and position our projects for success. (shrink)

This paper attempts a critical examination of the thesis that an apprenticeship to a Lancaster druggist was, for Edward Frankland, a wholly inappropriate preparation for a career in chemistry. This view, which stems directly from Frankland himself, is defective in several ways. It fails to take into account certain benefits which he accepted as valuable; it implies an exceptional degree of ‘negligence’ which was in fact quite typical; it ignores certain positive indicators of the value of such experience; and it (...) involves questionable value-judgments on the behaviour of one individual, the druggist Stephen Ross. Although Frankland's perspective may be no longer acceptable, the reasons for its inadequacy are perhaps the most important aspect of the whole affair. Their identification raises questions of historiography of wider significance, while the whole episode underlines certain issues in scientific training that were to become crucial in the growth of Victorian chemistry in Britain.

The aim of this paper is to explore the conditions under which generalisation from single case studies, in the sense of making inferences concerning a wider class of phenomena beyond a case, is reasonable. Two sets of conditions, in particular, provide the basis for our consideration of this issue. The first is an exploration of the impressive amount of empirical knowledge that is contained within the theories that are used to make observations, to classify phenomena, and to understand and interpret (...) cases. The second is recognition of the role of a pattern of inference known as abduction, or inference to the best explanation, in drawing conclusions from case studies. It is argued that these two conditions, when applied to the procedures for conducting case studies, can be used to defend, as reasonable, the making of certain provisional generalisations from single cases. An epistemological procedure for testing and further justifying these generalisations, with a particular emphasis on dealing with the problem of confirmation bias, is then discussed and recommended.

Practical quantum computing devices and their applications to AI in particular are presently mostly speculative. Nevertheless, questions about whether this future technology, if achieved, presents any special ethical issues are beginning to take shape. As with any novel technology, one can be reasonably confident that the challenges presented by "quantum AI" will be a mixture of something new and something old. Other commentators (Sevilla & Moreno 2019), have emphasized continuity, arguing that quantum computing does not substantially affect approaches to value (...) alignment methods for AI, although they allow that further questions arise concerning governance and verification of quantum AI applications. In this brief paper, we turn our attention to the problem of identifying as-yet-unknown discontinuities that might result from quantum AI applications. Wise development, introduction, and use of any new technology depends on successfully anticipating new modes of failure for that technology. This requires rigorous efforts to break systems in protected sandboxes, and it must be conducted at all stages of technology design, development, and deployment. Such testing must also be informed by technical expertise but cannot be left solely to experts in the technology because of the history of failures to predict how non-experts will use or adapt to new technologies. This interplay between experts and non-experts may be particularly acute for quantum AI because quantum mechanics is notoriously difficult to understand. (As Richard Feynman quipped, "Anyone who claims to understand quantum mechanics is either lying or crazy.") We will discuss the extent to which the difficulties in understanding the physics underlying quantum computing challenges attempts to anticipate new failure modes that might be introduced in AI applications intended for unsupervised operation in the public sphere.

Introduction Biobank-based research is growing in importance. A major controversy exists about the return of aggregate and individual research results. Methods The authors used a mixed-method approach in order to study parents' attitudes towards the return of research results regarding themselves and their children. Participants attended four 2-h, deliberative-engagement sessions held on two consecutive Saturdays. Each session consisted of an educational presentation followed by focus-group discussions with structured questions and prompts. This manuscript examines discussions from the second Saturday which focused (...) on the benefits and risks of returning aggregate and individual research results regarding both adults (morning session) and children (afternoon session). Attitudes were assessed in pre-engagement and post-engagement surveys. Results The authors recruited 45 African-American adults whose children received medical care at two healthcare facilities on the South Side of Chicago that serve different socioeconomic communities. Three dominant themes were identified. First, most participants stated that they would enrol themselves and their children in a biobank, although there was a vocal minority opposed to enrolling children, particularly children unable to participate in the consent process. Second, participants did not distinguish between the results they wanted to receive regarding themselves and their children. Supplemental survey data found no attitudinal changes pre-engagement and post-engagement. Third, participants believed that children should be allowed access to their health information, but they wanted to be involved in deciding when and how the information was shared. Discussion Participant attitudes are in tension with current biobank policies. An intensive educational effort had no effect on their attitudes. (shrink)

La figure de l’entrepreneur est aujourd’hui utilisée dans une grande variété de discours publics. Ce travail cherche à remonter à l’une des sources théoriques de la constitution de cette figure : la théorie de l’entrepreneur de Schumpeter (1911a et 1911b). Ce retour montre que Schumpeter, dans son contexte intellectuel et théorique, est amené à importer une anthropologie philosophique en économie, celle de Nietzsche, auteur largement lu dans l’Autriche du début du xx e siècle. En transposant, à l’intérieur de sa théorie (...) économique, certaines caractéristiques majeures du grand homme créatif nietzschéen dans la figure de l’entrepreneur, Schumpeter développe une explication originale de la nature dynamique du marché et de l’évolution économique. Néanmoins il importe aussi de Nietzsche une série d’ambiguïtés, notamment en ce qui concerne l’origine de l’exceptionnalité individuelle de l’entrepreneur, et plus particulièrement de sa puissance créatrice. Une seconde ambiguïté est très largement héritée, qui concerne l’extension du modèle de l’individu entrepreneur : constitue-t-il une théorie de l’action valable pour tous les individus ou uniquement pour un type d’individus particuliers? Comment concilier exceptionnalité de l’entrepreneur et norme d’un entreprenariat pour tous? La dernière partie de ce travail s’attache ainsi à explorer ces ambiguïtés, qui apparaissent chez Schumpeter et ses successeurs, notamment Israël Kirzner. Codes JEL : B13, B25, B31, B40. (shrink)

John Davis (_New Methuselahs_: _The Ethics of Life_ _Extension_, The MIT Press, Cambridge, 2018) advances a novel ethical analysis of longevity science that employs a three-fold methodology of examining the impact of life extension technologies on three distinct groups: the “Haves”, the “Have-nots” and the “Will-nots”. In this essay, I critically examine the egalitarian analysis Davis deploys with respect to its ability to help us theorize about the moral significance of an applied gerontological intervention. Rather than focusing on futuristic scenarios (...) of radical life extension, I offer a rival egalitarian analysis that takes seriously (1) the health vulnerabilities of today’s aging populations, (2) the health inequalities of the “aging status quo” and, (3) the prospects for the fair diffusion of an aging intervention over the not-so-distant future. Despite my reservations about Davis’s focus on “life-extension” vs. increasing the human “healthspan”, I agree with his central conclusion that an aging intervention would be, on balance, a good thing and that we should fund such research aggressively. But, I make an even stronger case and conjecture that an intervention that slows down the rate of molecular and cellular decline from the inborn aging process will likely be one of the most important public health advancements of the twenty-first century. This is so because aging is the most prevalent risk factor for chronic disease, frailty and disability, and it is estimated that there will be over 2 billion persons age > 60 by the year 2050.

One challenge in explaining neural evolution is the formal equivalence of different computational architectures. If a simple architecture suffices, why should more complex neural architectures evolve? The answer must involve the intense competition for resources under which brains operate. I show how recurrent neural networks can be favored when increased complexity allows for more efficient use of existing resources. Although resource constraints alone can drive a change, recurrence shifts the landscape of what is later evolvable. Hence organisms on either side (...) of a transition boundary may have similar cognitive capacities but very different potential for evolving new capacities. (shrink)

This review essay is occasioned by two books on the moral and political thought of William James. Sarin Marchetti’s Ethics and Philosophical Critique in William James and Trygve Throntveit’s William James and the Quest for an Ethical Republic pose crucial questions for how we are to frame, interpret, and assess the philosophical contributions of William James more than one hundred years after his passing. In offering interpretations of James as contributing to social and political questions through his moral philosophy, both (...) books raise important questions that bear on contemporary debates in political philosophy between ideal theorists and political realists. If ideal theorists put moral philosophy first and extract a political vision therefrom, political realists seek to begin theoretical reflection in the specifically political circumstances of our lives. This review essay is centered on the following question: through which of these two lenses should the writings of William James be received? (shrink)

This contribution to the final installment of the Common Knowledge symposium on contextualism is a reply to another contribution, Peter Burke's “Alternative Modes of Thought.” Or rather, this essay responds to the historians and social scientists whom Burke cites as arguing that only some ways of thinking are possible in any given place and time. Richmond's response is that a human context in which there is but one mode of thought in evidence, and no evident ambivalence regarding it, is a (...) context in which great numbers have died, violently and recently. His essay takes the form of a report on his eleven research visits since 1985 to the death camp at Auschwitz. In Nazi-occupied Europe, he concludes, “ ‘alternative modes of thought’ were by no means impossible. Rather, people who thought differently from the regime were gathered to Auschwitz and other such camps, then murdered and incinerated. The Nazi ‘mental framework,’ if that is what it was, had to be imposed, and the millions incapable of participating in it had to die rapidly.... The problem for us, in the Nazis’ wake, is that the their ‘mode of thought’ is so alien that we have yet to find a context that enables us to understand it.... The need, then, is not for the context that intellectual, cultural, and social historians might provide, but for the aid of phenomenologists, because what we are hoping to understand is—in the words of Thomas Nagel's essay ‘What Is It Like to Be a Bat?’—a ‘fundamentally alien form of life.’ ”.

On the basis of reports that Jan van Eyck visited England, this essay speculates freely on what the diplomat and painter actually did in and around London for three weeks in 1428. The essay claims, for example, that van Eyck went to the village of Foots Cray to buy watercresses to use as models when painting greenery on the Ghent Altarpiece of the Mystic Lamb. The recently erected gateway to the palace at Greenwich is said likewise to be the model (...) for a towered gateway depicted on the altarpiece. After providing local detail about relevant parts of England in 1428, the essay closes with speculation about the origin of a harp, of a purportedly Welsh variety, appearing on the altarpiece in the hands of an angel. The author argues that it was the instrument of an itinerant Breton musician whom van Eyck had heard in recital at the Poor Clares convent of the Holy Trinity at the Minories in Aldgate. The harpist subsequently murdered his Stepney landlady and was himself killed by enraged local housewives. Van Eyck is said to have purchased the man's harp when his worldly goods were posthumously sold. (shrink)
