Adult stem cell populations must coordinate their own maintenance with the generation of differentiated cell types to sustain organ physiology, in a spatially controlled manner and over long periods. Quantitative analyses of clonal dynamics have revealed that, in epithelia, homeostasis is achieved at the population rather than at the single stem cell level, suggesting that feedback mechanisms coordinate stem cell maintenance and progeny generation. In the central nervous system, however, little is known of the possible community processes underlying neural (...) stem cell maintenance. Recent work, in part based on intravital imaging made possible in the adult zebrafish, conclusively highlights that homeostasis in neural stem cell pools may rely on population asymmetry and long‐term spatiotemporal coordination of neural stem cell states and fates. These results suggest that neural stem cell assemblies in the vertebrate brain behave as self‐organized systems, such that the stem cells themselves generate their own intrinsic niche. (shrink)

Emmanuel Levinas (1906–1996) has exerted a profound influence on 20th-century continental philosophy. This anthology, including Levinas's key philosophical texts over a period of more than forty years, provides an ideal introduction to his thought and offers insights into his most innovative ideas. Five of the ten essays presented here appear in English for the first time. An introduction by Adriaan Peperzak outlines Levinas's philosophical development and the basic themes of his writings. Each essay is accompanied by a brief (...) introduction and notes. This collection is an ideal text for students of philosophy concerned with understanding and assessing the work of this major philosopher. (shrink)

The thirteen essays collected in this volume investigate the possibility that the word "God" can be understood now, at the end of the twentieth century, in a meaningful way. Nine of the essays appear in English translation for the first time. Among Levinas's writings, this volume distinguishes itself, both for students of his thought and for a wider audience, by the range of issues it addresses. Levinas not only rehearses the ethical themes that have led him to be regarded as (...) one of the most original thinkers working out of the phenomenological tradition, but he also takes up philosophical questions concerning politics, language, and religion. The volume situates his thought in a broader intellectual context than have his previous works. In these essays, alongside the detailed investigations of Husserl, Heidegger, Rosenzweig, and Buber that characterize all his writings, Levinas also addresses the thought of Kierkegaard, Marx, Bloch, and Derrida. Some essays provide lucid expositions not available elsewhere to key areas of Levinas's thought. "God and Philosophy" is perhaps the single most important text for understanding Levinas and is in many respects the best introduction to his works. "From Consciousness to Wakefulness" illuminates Levinas's relation to Husserl and thus to phenomenology, which is always his starting point, even if he never abides by the limits it imposes. In "The Thinking of Being and the Question of the Other," Levinas not only addresses Derrida's Speech and Phenomenon but also develops an answer to the later Heidegger's account of the history of Being by suggesting another way of reading that history. Among the other topics examined in the essays are the Marxist concept of ideology, death, hermeneutics, the concept of evil, the philosophy of dialogue, the relation of language to the Other, and the acts of communication and mutual understanding.

The “private” dimension of social life is problematic, posing conceptual, political, and ecological challenges. Some of these problems arise from the very nature of private property as it is enshrined in social life, which demands special privileges be granted to “private” matters on the grounds that these are private, because the predominant representation of the involved rights is that they reflect claims of the holders, rather than legitimate claims of society as a whole in allocating responsibilities, benefits, and duties. (...) The claim to the rationality of allocations of property rights, this article argues, must be questioned in light of the kind of commonality that is revealed in a striking manner by environmental issues (although it is not restricted to environmental matters). This questioning makes sense in relation to an analysis of social interactions, beyond the problematic opposition between the private sphere and public life. (shrink)

A sequel to Levinas's Totality and Infinity, this work is generally considered Levinas's most important contribution to the contemporary debate surrounding the closure of metaphysical discourse, much commented upon by Jacques Derrida. This work contains a fundamentally original theory of the ethical relationship and describes the face-to-face relationship, sensibility, responsibility and speech. Renowned Levinas scholar Richard A. Cohen has contributed a new foreword to this edition of Otherwise than Being, which is also the first time the work is available (...) in an affordable paperback edition. This foreword, along with Alphonso Lingis's extensive introduction to the work, is a valuable tool for researchers and students of Levinas's philosophy. (shrink)

A sequel to Levinas' Totality and Infinity.

Emmanuel Levinas is a major voice in twentieth century European thought. Beginning his intellectual career in the 1920s, he has developed an original and comprehensive post rationalist ethics of social responsibility and obligation. The influence of his work has already been profound and far-reaching, readily acknowledged by such diverse and important figures as Jean-Paul Sartre, Jacques Derrida, and Enrique Dussel. Time and The Other was first presented as a series of lectures in 1946-47 at the College Philosophique and is (...) probably the clearest statement of Levinas' thought. Along with Existence and Existents (1947), it represents the first formulation of Levinas' own philosophy, later more fully developed in Totality and Infinity (1961) and Otherwise than Being or Beyond Essence (1974. (shrink)

As Emmanuel Levinas states in the preface to Existence and Existents, "this study is a preparatory one. It examines . . . the problem of the Good, time, and the relationship with the other [person] as a movement toward the Good." First published in 1947, and written mostly during Levinas's imprisonment during World War II, this work provides the first sketch of his mature thought later developed fully in Totality and Infinity and Otherwise than Being, or Beyond Essence. (...) This new edition marks the first time this important work has been made available in an inexpensive paperback edition. Levinas's project in Existence and Existents is to move from anonymous existence to the emergence of subjectivity; to subjectivity's practice, theory and morality; to its encounter with the alterity of the other person. He is concerned here primarily with the time of the solitary subject; time is the inner structure of subjectivity, of the movement of existing. "Levinas's work," says Alphonso Lingis, "contains not only wholly new analyses of the forms of time of the present, the past, the future but also a new conception of the work of time." Beginning with Existence and Existents, then, it is possible to begin tracing the progressive "alterization" of time as it unfolds across the development of Levinas's entire philosophy. As a "preparatory" study, Existence and Existents introduces the major themes and concerns that occupied Levinas throughout his career. This is essential reading for understanding both Levinas's own philosophy and the developments in philosophical thought in the twentieth century. (shrink)

Emmanuel Levinas is one of the most important figures of twentieth-century philosophy. Exerting a profound influence upon such thinkers as Derrida, Lyotard, Blanchot, and Irigaray, Levinas's work bridges several major gaps in the evolution of continental philosophy -- between modern and postmodern, phenomenology and poststructuralism, ethics and ontology. He is credited with having spurred a revitalized interest in ethics-based philosophy throughout Europe and America. Entre Nous is the culmination of Levinas's philosophy. Published in France a few years before his (...) death, it gathers his most important work and reveals the development of his thought over nearly forty years of committed inquiry. Along with several trenchant interviews published here, these essays engage with issues of suffering, love, religion, culture, justice, human rights, and legal theory. Taken together, they constitute a key to Levinas's ideas on the ethical dimensions of otherness. Working from the phenomenological method of Edmund Husserl and Martin Heidegger, Levinas pushed beyond the limits of their framework to argue that it is ethics, not ontology, that orients philosophy, and that responsibility precedes reasoning. Ethics for Levinas means responsibility in relation to difference. Throughout his work, Levinas returns to the metaphor of the face of the other to discuss how and where responsibility enters our lives and makes philosophy necessary. For Levinas, ethics begins with our face to face interaction with another person -- seeing that person not as a reflection of one's self, nor as a threat, but as different and greater than self. Levinas moves the reader to recognize the implications of this interaction: our abiding responsibility for the other, and our concern with the other's suffering and death. Situated at the crossroads of several philosophical schools and approaches, Levinas's work illuminates a host of critical issues and has found resonances among students and scholars of literature, law, religion, and politics. Entre Nous is at once the apotheosis of his work and an accessible introduction to it. In the end, Levinas's urgent meditations upon the face of the other suggest a new foundation upon which to grasp the nature of good and evil in the tangled skein of our lives. (shrink)

ABSTRACT While the first generation of the so-called Frankfurt School has promoted a strong interconnection between social critique and knowledge of the social world, contemporary critical theory seems to consider that epistemological issues don’t deserve anymore consideration. Is it really possible to elaborate a convincing theory of social critique without taking seriously the various links between social critique and knowledge? This article argues that the answer is no. In a first step, it recalls the ways in which the philosophical debate (...) about social critique is currently articulated and how it disconnects social critique and knowledge. One of the reasons for such a disconnection relates to a vision of politics as consisting mainly in a conflict between normative principles, notably between conceptions of social justice. This vision of politics is criticized in the second step of this paper. A second reason, examined in the third part of the paper, relates to the risk of epistemic violence. The shared but questionable assumption is that any sociological or philosophical attempt to produce knowledge would necessarily lead to epistemic violence rather than to epistemic empowerment.

Fake news can originate from an ordinary person carelessly posting what turns out to be false information or from the intentional actions of fake news factory workers, but broadly speaking it can also originate from scientific fraud. In the latter case, the article can be retracted upon discovery of the fraud. A case study shows, however, that such fake science can be visible in Google even after the article was retracted, in fact more visible than the retraction notice. We (...) hypothesize that the reason for this lies in the popularity-based logic governing Google, in particular its foundational PageRank algorithm, in conjunction with a psychological law which we refer to as the “law of retraction”: a retraction notice is typically taken to be less interesting and therefore less popular with internet users than the original content retracted. We conduct an empirical study drawing on records of articles retracted due to fraud in the Retraction Watch public database. The study tests the extent to which such retracted scientific articles are still highly ranked in Google –and more so than information about the retraction. We find, among other things, that both Google Search and Google Scholar more often than not ranked a link to the original article higher than a link indicating that the article has been retracted. Surprisingly, Google Scholar did not perform better in this regard than Google Search.We also found cases in which Google did not track the retraction of an article on the first result page at all. We conclude that both Google Search and Google Scholar run the risk of disseminating fake science through their ranking algorithms. (shrink)

The presupposition triggered by an expression E is generally satisfied by information that comes before rather than after E in the sentence or discourse. In Heim’s classic theory (1983), this left-right asymmetry is encoded in the lexical semantics of dynamic connectives and operators. But several recent analyses offer a more nuanced approach, in which presupposition satisfaction has two separate components: a general principle (which varies from theory to theory) specifies under what conditions a presupposition triggered by an expression E (...) is satisfied; and an ‘incremental’ component specifies that the principle must be checked on the basis of information that comes before E. Several researchers take this incremental component to be a processing bias, which can be overcome at some cost. If so, it should be possible, though costly, to satisfy presuppositions ‘symmetrically’, i.e. by taking into account linguistic material that comes both before and after the presupposition trigger. We test this claim with experimental means. Using inferential (and to some extent acceptability) tasks involving the anaphoric trigger aussi (‘too’) in French, we argue that symmetric readings are indeed possible (albeit degraded) in environments involving the connectives if, or, and unless.

Reasoning research suggests that people use more stringent criteria when they evaluate others' arguments than when they produce arguments themselves. To demonstrate this “selective laziness,” we used a choice blindness manipulation. In two experiments, participants had to produce a series of arguments in response to reasoning problems, and they were then asked to evaluate other people's arguments about the same problems. Unknown to the participants, in one of the trials, they were presented with their own argument as if it (...) was someone else's. Among those participants who accepted the manipulation and thus thought they were evaluating someone else's argument, more than half rejected the arguments that were in fact their own. Moreover, participants were more likely to reject their own arguments for invalid than for valid answers. This demonstrates that people are more critical of other people's arguments than of their own, without being overly critical: They are better able to tell valid from invalid arguments when the arguments are someone else's rather than their own.

The philosophy of Hitler is simplistic [primaire]. But the primitive powers that burn within it burst open its wretched phraseology under the pressure of an elementary force. They awaken the secret nostalgia within the German soul. Hitlerism is more than a contagion or a madness; it is an awakening of elementary feelings.But from this point on, this frighteningly dangerous phenomenon becomes philosophically interesting. For these elementary feelings harbor a philosophy. They express a soul's principal attitude towards the whole of (...) reality and its own destiny. They predetermine or prefigure the meaning of the adventure that the soul will face in the world.The philosophy of Hitlerism therefore goes beyond the philosophy of Hitlerians. It questions the very principles of a civilization. The conflict is played out not only between liberalism and Hitlerism. Christianity itself is threatened in spite of the careful attentions or Concordats that the Christian churches took advantage of when Hitler's regime came to power.But it is not enough to follow certain journalists in distinguishing between Christian universalism and racist particularism: a logical contradiction cannot judge a concrete event. The meaning of a logical contradiction that opposes two forms of ideas only shows up fully if we go back to their source, to intuition, to the original decision that makes them possible. It is in this spirit that we are going to set forth the following reflections. Emmanuel Levinas has been professor of philosophy at the Ecole Normale Superieure Israelite de Paris and at the University of Paris I . Among his books that have been translated into English are Totality and Infinity, Ethics and Infinity, Otherwise Than Being or Beyond Essence, and The Levinas Reader.

This paper contrasts the Hegelianism of contemporary neo-pragmatism and the Hegelianism of classical pragmatism as it has been reassessed in contemporary Deweyan scholarship. Drawing on Dewey’s interpretation of Hegel, this paper argues that Hegel’s theory of the spirit is in many aspects more akin to Dewey’s pragmatism than Brandom’s. The first part compares Dewey’s pragmatism with Hegel’s conceptions of experience and the theory/practice relation. The second part compares Dewey’s naturalism with Hegel’s theory of the relation between nature and spirit.

I learned very early, perhaps even before 1933 and certainly after Hitler’s huge success at the time of his election to the Reichstag, of Heidegger’s sympathy toward National Socialism. It was the late Alexandre Koyré who mentioned it to me for the first time on his return from a trip to Germany. I could not doubt the news, but took it with stupor and disappointment, and also with the faint hope that it expressed only the temporary lapse of a great (...) speculative mind into practical banality. It cast a shadow over my firm confidence that an unbridgeable distance forever separated the delirious and criminal hatred voiced by Evil on the pages of Mein Kampf from the intellectual vigor and extreme analytical virtuosity displayed in Sein und Zeit, which had opened the field to a new type of philosophical inquiry.Could one question the incomparable impression produced by this book, in which it immediately became apparent that Heidegger was the interlocutor and equal of the greatest—those very few—founders of European philosophy? that here was someone, this seemed obvious, all modern thought would soon have to answer?

I argue that a general feature of human psychology provides strong reason to modify or reject anti-reductionism about the epistemology of testimony. Because of the work of what I call “the background” (which is a collection of all of an individual's synthetizations, summarizations, memories of experiences, beliefs, etc.) we cannot help but form testimonial beliefs on the basis of a testifier's say so along with additional evidence, concepts, beliefs, and so on. Given that we arrive at testimonial beliefs through the (...) work of the background, to be justified in holding a testimonial belief, we must not only have a rational speaker's say so, but we must also form such beliefs in a right way. If this is right, then, contrary to typical anti-reductionism, justified testimonial beliefs require more than just a trustworthy testifier's say so – another requirement is that they are formed in a right way.

The attempt to employ quantum principles for modeling cognition has enabled the introduction of several new concepts in psychology, such as the uncertainty principle, incompatibility, entanglement, and superposition. For many commentators, this is an exciting opportunity to question existing formal frameworks (notably classical probability theory) and explore what is to be gained by employing these novel conceptual tools. This is not to say that major empirical challenges are not there. For example, can we definitely prove the necessity for quantum, as (...) opposed to classical, models? Can the distinction between compatibility and incompatibility inform our understanding of differences between human and nonhuman cognition? Are quantum models less constrained than classical ones? Does incompatibility arise as a limitation, to avoid the requirements from the principle of unicity, or is it an inherent (or essential?) characteristic of intelligent thought? For everyday judgments, do quantum principles allow more accurate prediction than classical ones? Some questions can be confidently addressed within existing quantum models. A definitive resolution of others will have to anticipate further work. What is clear is that the consideration of quantum cognitive models has enabled a new focus on a range of debates about fundamental aspects of cognition. (shrink)

The philosophy is a discipline that is not a science and that is unfamiliar to the general public who sees in it a form of original reflection. To understand this originality,you have to remember of the beginning of the history of philosophy which, from the end of Antiquity, gave up his first goal, namely wisdom. From Emperor Justinian who closed all schools of philosophy in 533 AD, philosophy has survived while remaining a discourse (logos) disconnected from its action ; However, (...) this action was sophia (wisdom). Consider then that Philosophy has been dead for 15 centuries and that the philosophers have survived by submitting to the authority in place, first to Theocracy and therefore to the Church, then to the State and therefore to Public Education. In the first case, philosophers are more interested in Faith and Holiness than in meditation and wisdom ; in the second case, they prefer to teach and write rather than dialogue to develop a peaceful way of life. Philosophy has strayed from it’s goal – Wisdom. It is therefore a question of reviving Philosophy by reopening schools which teach a wisdom. (shrink)

BackgroundThe safety of sleeping pills has increased dramatically during the last 100 years, from barbiturates to bensodiazepines to modern day so-called Z-drugs.MethodsThe circumstances of prescribing sleeping pills in the early 20th century are illustrated by summarizing the main storyline of a novel by Swedish writer Vilhelm Moberg. This is followed by a thought experiment and a theoretical discussion.ResultsIn his 1937 novel Sömnlös (Swedish for sleepless) Vilhelm Moberg portrayed existential and relational distress in relation to insomnia. In a thought experiment, past (...) progresses in sleeping pills safety are projected into the future. Thereby, it is claimed that important issues in the area of philosophy of medicine come to the fore. This leads to a theoretical discussion about broader questions concerning the role of the physician, the goals of medicine (as described by Lennart Nordenfelt), the concept of pharmaceuticalisation (as described notably by sociologist of sleep Simon J. Williams and co-workers), and health enhancement (c.f. Carl Elliott and the alleged wish to be better than well).ConclusionInsomnia is a prism through which important philosophical and sociological questions related to the practice of medicine can be asked.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 61.4 (2000) 691-698 [Access article in PDF] Hume, Race, and Human Nature Emmanuel C. Eze Introduction John Immerwahr recently wrote in the Journal of the History of Ideas, "While Hume is generally known as an enemy of prejudice and intolerance, he is also infamous as a proponent of philosophical racism." 1 I am intrigued by this suggestion that Hume's is a "philosophical (...) racism"; one wonders: how many brands of racisms are there? What does "philosophical" racism mean? Assuming that philosophical racism is something which we wish to take notice of, what part of Hume's philosophy sustains it? How much of Hume's philosophy may be affected by this, and how profound?On the surface it seems not to make sense to ask, for example, how profound Hume's "philosophical racism" is or how deeply racist his philosophical works may be. The question appears contrived because, currently, every reference in the literature seem to point to only a footnote: I am apt to suspect the Negroes and in general all other species of men (for there are four or five different kinds) to be naturally inferior to the whites. There never was a civilized nation of any other complexion than white, nor even any individual eminent either in action or speculation. No ingenious manufacturers amongst them, no arts, no sciences. On the other hand, the most rude and barbarous of the whites, such as the ancient GERMANS, the present TARTARS, have still something eminent about them, in their valour, form of government, or some other particular. Such a uniform and constant difference could not happen, in so many countries and ages, if nature had not made an original distinction betwixt these breeds of men. Not to mention our colonies, there are NEGROE slaves dispersed all over EUROPE, of which none ever discovered [End Page 691] any symptoms of ingenuity; tho' low people, without education, will start up amongst us, and distinguish themselves in every profession. In JAMAICA, indeed, they talk of one negroe as a man of parts and learning; but 'tis likely he is admired for very slender accomplishments, like a parrot, who speaks a few words plainly. 2This was added, between 1753 and 1754, to the essay "Of National Characters." It was also revised in the final edition of the Essays: Moral, Political and Literary, which Hume had prepared shortly before he died in 1777. 3 Meanwhile, the original version of "Of National Characters" was written in 1748.An equally reasonable point of view on the matter, however, is to show that, far from being philosophically unimportant or an after-thought, the footnote, both its addition several years after the original essay was written and its maintenance in the subsequent revisions by Hume, suggests that the ideas expressed therein were important to the author and, significantly, to the arguments of "Of National Characters." It is known that by 1770 James Beattie, in An Essay on the Nature and Immutability of Truth, in Opposition to Sophistry and Skepticism, had extensively criticized "Of National Character," specifically the note under consideration. Hume was aware of this and other criticisms and responded or commented on them in letters to friends, among other places. In a letter to his friend and publisher, William Straham, later published in London Chronicle (12-14 June 1777), Hume discussed dismissively criticisms from Thomas Reid and James Beattie, referring to the latter as "a bigoted silly fellow." 4 The fact that it survived Hume's multiple revisions and remained part of the Essays and was publicly defended from criticisms invites one not to dismiss this lengthy addition as marginal to Hume's thought but rather to determine why he might have felt it needed to be added in the first place, revised, and critically defended in what is now its definitive version. Relevant specific questions would be: why, of all other possible places (I have in mind, for example, a comparable essay "Of the populousness of ancient nations"), was the footnote added here? How does the opinion in this note relate to... (shrink)

Paying more attention to the rhetorical side of argumentation raises epistemological questions. In this article I argue that rhetoric has to be an integral part of argumentative models if such models are to be considered rational.

I hope to show that it is not the case, if we consider rationality to be a concept that encompasses more (...) class='Hi'>than just a strictly logical way of thinking.

The Barth–Krabbe–Hintikka–Hintikka Problem, independently raised by Barth and Krabbe and Hintikka and Hintikka Sherlock Holmes confronts modern logic: Toward a theory of information-seeking through questioning.

We solve the problem by providing a set of preferences for players with bounded rationality and specifying strategic inferences from those preferences, for a variant of (...) logical dialogues. This solution is generalized to both game-theoretic semantics and orthodox dialogical logic. (shrink)

Though Kierkegaard never explicitly formulated a theory of religious doctrine, he did have a clear position on the role that Christian doctrine ought to play in the lives of believers. Briefly stated, he maintained that Christianity, as a human activity, involves more than merely believing certain propositions about matters of fact. The doctrines of Christianity take on a true religious significance only when they are given the power to transform the lives of those who accept them; only when they (...) are given expression in the existence of the believer. This was, however, far from evident to Kierkegaard's theological contemporaries who, in the collective absentmindedness of the age, sought to replace the Christian virtue of faith with the philosophical ideal of objective knowledge.

Critical (necessary or sufficient) features in categorisation have a long history, but the empirical evidence makes their existence questionable. Nevertheless, there are some cases that suggest critical feature effects. The purpose of the present work is to offer some insight into why classification decisions might misleadingly appear as if they involve critical features. Utilising Tversky's (1977) contrast model of similarity, we suggest that when an object has a sparser representation, changing any of its features is more likely to lead to (...) a change in identity than it would in objects that have richer representations. Experiment 1 provides a basic test of this suggestion with artificial stimuli, whereby objects with a rich or a sparse representation were transformed by changing one of their features. As expected, we observed more identity judgements in the former case. Experiment 2 further confirms our hypothesis, with realistic stimuli, by assuming that superordinate categories have sparser representations than subordinate ones. These results offer some insight into the way feature changes may or may not lead to identity changes in classification decisions. (shrink)

Fossil remains witness the relationship between the appearance of the middle ear and the expansion of the brain in early mammals. Nevertheless, the lack of detachment of ear ossicles in the mammaliaform Morganucodon, despite brain enlargement, points to other factors that triggered brain expansion in early mammals. Moreover, brain expansion in some early mammalian groups seems to have favored brain regions other than the cortex.

Since special relativity and quantum mechanics, information has become a central concept in our description and understanding of physical reality. This statement may be construed in different ways, depending on the meaning we attach to the concept of information, and on our ontological commitments. One distinction is between mind-independent ‘Shannon information’ and a traditional conception of information, connected with meaning and knowledge. Another, orthogonal, distinction is between information considered as a fundamental physical entity, and an ontological agnosticism where physics is (...) about our information of the world rather than about the world itself. Combinations of these lead to various possibilities. I argue that adopting mind-independent information as ontologically fundamental is a hitherto undefended position with important advantages. This position appears similar to Floridi’s informational structural realism, but is fundamentally different. Rather than ‘epistemically indistinguishable differences’, it requires a robust conception of information as consisting of readable and interpretable messages. (shrink)

In his plea for consensual democracy in Africa, Kwasi Wiredu recommends unanimity about what is to be done, not what ought to be done, or unanimity on action rather than unanimity of values, beliefs and opinion. I caution the use of this procedural instrument by showing that some issues are so value-laden that a group decision cannot be value-neutral. It may sometimes be more productive to entertain value differences to keep them from going underground and becoming dangerous. However, the (...) ability to locate some common interest or ground seems to be crucial for such value confrontation. (shrink)

According to Wiredu, the Akan profess secular esteem rather than religious worship to supra-natural beings, who they perceive in an empirical sense. He backs this up by re-reading what he sees as the Akan general ontology in a way that denies them of the concepts of the supernatural, the transcendental, the mental, the spiritual, and an ontologically distinct mind. At the end of denying the three criteria of worship as well as all of these other concepts which might otherwise (...) be available to the Akan, one might struggle to find any evidence that the Akan even had a religion. I dispute this secular reading, and I more generally demonstrate that the characterizations of the Akan attitude to divinity as non-worshipping, non-supernatural, non-transcendent, and non-spiritual, are either conceptually flawed, factually incorrect, or both.

: A popular belief is that the process whereby search engines tailor their search results to individual users, so-called personalization, leads to filter bubbles in the sense of ideologically segregated search results that would tend to reinforce the user’s prior view. Since filter bubbles are thought to be detrimental to society, there have been calls for further legal regulation of search engines beyond the so-called Right to be Forgotten Act. However, the scientific evidence for the filter bubble hypothesis is surprisingly (...) limited. Previous studies of personalization have focused on the extent to which different users get different results lists without taking the content on the webpages into account. Such methods are unsuitable for detecting filter bubbles as such. In this paper, we propose a methodology that takes content differences between webpages into account. In particular, the method involves studying the extent to which users with strong opposing views on an issue receive search results that are correlated content-wise with their personal view. Will users of with strong prior opinion that X is true on average have a larger share of search results that are in favor of X than users with a strong prior opinion that X is false? We illustrate our methodology at work, but also the non-trivial challenges it faces, by a small-scale study of the extent to which Google Search leads to ideological segregation on the issue of man-made climate change.

If semantic consequence is analyzed with extensive games, logical reasoning can be accounted for by looking at how players solve entailment games. However, earlier approaches to game semantics cannot achieve this reduction, by want of explicitly dened preferences for players. Moreover, although entailment games can naturally translate the idea of argumentation about a common ground, a cognitive interpretation is undermined by the complexity of strategic reasoning. We thus describe a class of semantic extensive entailment game with algorithmic players, who have (...) preferences for parsimonious spending of computational resources and thus compute partial strategies under qualitative uncertainty about future histories. We prove the existence of local preferences for moves and of strategic fixpoints that allow to map game-trees to tableaux proofs, and exhibit a strategy prole that solves the fixpoint selection problem, and can be mapped to systematic constructions of semantic trees, yielding a completeness result by translation. We then discuss the correspondence between proof heuristics and strategies in our games, the relations of our games to gts, and possible extensions to other entailment relations. We conclude that the main interest of our result lies in the possibility to bridge argumentative and cognitive models of logical reasoning, rather than in new meta-theoretic results. All proofs are given in appendix. (shrink)

This volume is Mounier's final definition of personalism. First published less than a year before his death in 1950, it is a beautifully written, clear yet unsystematic statement of personalism.

Several factors have been put forward to explain the variability of moral judgments for superficially analogous moral dilemmas, in particular in the paradigm of trolley cases. In this paper we elaborate on Mikhail's view that (i) causal analysis is at the core of moral judgments and that (ii) causal judgments can be quantified by linguistic methods. According to this model, our moral judgments depend both on utilitarian considerations (whether positive effects outweigh negative effects) and on a representation of the causal (...) structure of the action (whether the negative effects are essentially side-effects rather than main goals). However, the exact contribution of each factor, as well as the precise way in which causal considerations interact with utilitarian considerations, has yet to be quantified and investigated. We present several variations on trolley dilemmas in which subjects had to assess the morality of the action and to evaluate their preference between two competing descriptions of the scene (..

This paper investigates how Edward Pusey, a nineteenth century Anglican clergy and scholar responded to Edward Manning’s claim that the Church of England is not an authentic church. This led the former to write his Eirenicon, as an intellectual justification and a response to apostolicity and catholicity of the Anglican faith. Eirenicon is an example in rigorous dialogue on religious faith claims. The ecumenical rapprochement suggested by Pusey is very insightful: emphasis on the elements that unites Roman Catholics and Anglicans (...) as rooted in traditions of the Apostolic Church. After more than 152 years, this work seeks for the relevance of Pusey’s Eirenicon in contemporary Roman Catholic–Anglican faith relationship. (shrink)

This paper reports an experimental comparison of attitudes toward time and toward money in experience-based decisions. Preferences were elicited under rank-dependent utility for prospects with two or three consequences expressed either in time or in monetary units. Probabilities were unknown but learned through sampling. More specifically, time and money were compared under two conditions. In a first experiment, both consequences and probabilities of prospects were unknown and learned through sequential sampling. In a second experiment, the possible consequences were revealed after (...) the sampling. A real incentive system was implemented for both time and money. The heterogeneity of preferences was assessed for time and for money through individual and mixed modeling estimations. We observe that the nature of consequences (time or money) modifies probability weighting in terms of elevation and sensitivity. Subjects exhibit more optimism and less sensitivity to probability changes when deciding about time than about money. Revealing the consequences impacts the shape of the utility function and leaves probability weighting unchanged. We also observe that the real incentives have no effect except for the reduction in decision errors. This effect is stronger for money than for time. (shrink)

When people are united in their suffering for a common cause, that which binds them together is always stronger than their differences. The bond is even sturdier when religious motives define their common convictions. For this reason, during martyrdom, those who are persecuted create peculiar reli - gious identity through their common belief in God. This identity generates a socializing bond which makes them resolute in their united witness to the su - bject of their faith. This was the (...) case with the nineteenth-century Ugandan martyrs who died during the reign of the morally debased King Kabaka Mwan - ga. The novelty of this work consists in accentuating the ecumenicity of the Ugandan martyrdom that came into prominence, inter alia , through the Roman Catholic processes of canonization. It is so because there is no research work that has highlighted the fact that Anglicans and Lutherans were equally put to death in their defence of the Christian beliefs and morality alongside the Ro - man Catholics. For this reason, this work underlines how an inclusive narrative of the East-African Christian witness to the truth of the gospel brings out the ecumenicity of the Ugandan martyrologic events. Theoretical frameworks of deterrence and group memory were used in the understanding martyrdom and common witnessing in Uganda. In their united witnessing to the Christian faith, the Ugandan martyrs overcame the shackles of denominational divide that co - uld have weakened their common resolve to stand for Christ. Therefore, Chri - stians in contemporary African continent are called to re-receive the spirit of united witnessing to Christ as exhibited by the Ugandan martyrs since this will go a long way to: healing the wounds caused by denominational rivalry, con - trolling the tendency of tearing one another apart because of ethnic interests, sustaining common witness to truth and justice, encouraging all those suffering for their belief in Christ (no matter their denominational rootedness) to stand firm, and strengthening the spiritual bond that connects together all believers in Christ.

Newman remains an ecumenical figure held in high esteem by Roman Catholics and Anglicans. His ecumenical hermeneutics is observable in Tract No. 90. This Tract is a re-reading of the Thirty-nine Articles of Religion ratified in 1571 as the fundamentals of the Anglican faith. This tract is the product of the Oxford Movement that returned to the Antiquity in view of resolving the Anglican faith crises epitomized by erastianism. This return to the Fathers of the Church had a lot of (...) implications for the Anglican faith. Influenced by Antiquity, Newman rediscovered the common grounds between the Anglican faith and the church Catholic that inheres in the Roman Church. Thus, Tract No. 90 demonstrated that more things united the Nineteenth Anglicans and the Roman Catholics than what separated them. (shrink)

In the early 1990s, W.J.T. Mitchell and Gottfried Boehm independently proclaimed that the humanities were witnessing a ‘pictorial’ or ‘iconic turn’. Twenty years later, we may wonder whether this announcement was describing an event that had already taken place or whether it was rather calling forth for it to happen. The contemporary world is, more than ever, determined by visual artefacts. Still, our conceptual arsenal, forged during centuries of logocentrism, still falls behind the complexity of pictorial meaning. The essay (...) has two parts. In the first, it tries to assess the exact meaning of the ‘pictorial’/’iconic turn’, and (re)places it into the context of Anglo-American visual studies and German Bildwissenschaften. It the second, it addresses the famous claim by the philologist Ernst Robert Curtius that ‘image sciences are easy’ by advocating for three ‘turns of the screw’ to make visual studies more difficult: a shift from iconology to symptomatology, a shift from extensive to intensive and a shift from the indicative to the subjunctive.

In the constitution of contemporary image theory, Ludwig Wittgenstein’s philosophy has undoubtedly become a major conceptual reference. Rather than trying to establish what Wittgenstein’s own image theory could possibly look like, this paper would like to critically assess some of the advantages as well as some of the quandaries that arise when using Wittgenstein’s concept of ‘seeing-as’ for addressing the plural realities of images. While putting into evidence the tensions that come into play when applying what was initially a (...) theory of the gaze to a theory of the image, the paper shall subsequently discuss three modes of iconic vision: the propositional seeing-as, the projective seeing-in and the medial seeing-with.

What does God do with the “holes” or “troumatisms” that comprise the limits of our existence, that “original solitude” whereby we are confronted with the impending annihilation of all sense? Are we left enclosed in it or does God accompany us there? This essay considers to what extent Christ’s descent on Holy Saturday takes part in the extra-phenomenal “impossibility of possibility” of this original solitude. Such a consideration requires distinguishing between that “underworld” Christ descends to on the Second Day from (...) the sin that is the proper domain of “hell.” Christ descending to the underworld marks God entering our finitude so it may be transformed (Holy Saturday) rather than our faults so that we may be resurrected (Last Judgment). Philosophically, Holy Saturday, as the ab-sense and non-sense residing between Crucifixion (Good Friday) and Resurrection (Easter Sunday), exemplifies the extra-phenomenal in which nothing is manifested (phenomenology) nor signified (hermeneutics). This intermediate realm is then one in which God comes to meet us at the limit of our own finitude. (shrink)

“A Tempest in a Skull”. The expression comes from Victor Hugo's Les Miserables, but it says just as much about Freud's life as it does about ours. No one is probably more 'disturbed', or descends to the depths of chaos, than when he or she takes on the trappings of a 'tidy' being, or is caught up in a cosmetic life apparently made of order and beauty. Of course, “everything is fine” does not always hide “everything is bad”. But (...) we must also recognize that there is often a 'tempest' in a skull, and that it is precisely at this moment that everything changes, and everything is modified within us. Based on this phenomenon, the leitmotiv "so much exception, so much modification" thus becomes the new imperative of phenomenology - not out of attachment to the tragic or the pathetic, but on the contrary to reach that part of us which is inexpressible and which is the strongest part of our existentiality. Garcia Lorca's Duende, as the “spirit of aching Spain”, will express in its own way this force “that burns the blood”, the only one capable of touching our own depths, magnified and exorcised by the rhythm of Andalusian singers.

Spontaneous creations often exist in nature but rarely in philosophy. Yet, theemergence of the International Network of Philosophy of Religion was such an instance. France and the United States have long been linked, not just in friendship, but in thought. Paul Ricoeur, Jacques Derrida, and, more recently, Jean-Luc Marion have been among some of the French pioneers bridging this divide. More than a matter of an affiliation to a particular school of thought, a true“bridge of friendship” has been constructed (...) across the ocean, as if these waters were not enough to separate us.

“The final task of phenomenology as a philosophy of consciousness,” Merleau-Ponty wrote, “is to understand its relationship with non-phenomenology. That which resists phenomenology in us – natural being, the ‘barbaric principle’ of which Schelling spoke – cannot remain extra-phenomenal and must have its place within it.” The barbaric principle, and the there is – such is the confrontation that must be attempted here. Far from remaining simply pre-reflexive or presupposing the signified, the Nietzschean ‘abyss’, even more radical than the (...) Schellingian ‘groundless ground’, is an invitation for us today to probe what could also stand ‘outside the phenomenon’. (shrink)

It might be surprising to find in a journal of contemporary philosophy a text that is mostly about Hugh of St. Victor. The hermeneutic question, however, did not begin only yesterday. While this question has its actual sources in Origen and Saint Augustine, it is in the Didascalicon or The Art of Reading by Hugh of St. Victor that it first finds its clearest formulation and its most methodical development. This “hidden source of hermeneutics” allows for a questioning of the (...) foundations of the hermeneutics of the text from its outset, and also for a return of hermeneutics, or better to turn it, to its primordial origin: a hermeneutics of the “world” or of “creation” [ liber mundi ], rather than of the “text” and of “Scripture” [ liber Scripturae ]. A “Catholic” hermeneutics of “the body and the voice” should, in my opinion, take the place of the “Protestant” hermeneutics of “the meaning of the text” and the “Jewish” hermeneutics of the “body of the letter”. This thesis, which is stated and developed in my book Crossing the Rubicon, has its roots and justification in this historical essay on Hugh of St. Victor. (shrink)

As Hans Urs von Balthasar has put it, “nothing is more typical of [St. Bonaventure] than the prologue to the whole commentary on the Sentences.”Hans Urs von Balthasar, The Glory of the Lord: A Theological Aesthetics, vol.

This remark is the inspiration for the following rereading of Bonaventure’s inaugural lecture. Not only does the Commentary succeed to (...) a remarkable degree in unifying scholasticism and mysticism, but it also contains the seeds of a descriptive theological method that is original in ways that parallel contemporary phenomenological thought, despite the risk of anachronism inherent in such a claim.
