Quantum walks exhibit different properties compared with classical random walks, most notably by linear spreading and localization. In the meantime, random walks that replicate quantum walks, which we refer to as quantum-walk-replicating random walks, have been studied in the literature where the eventual properties of QWRW coincide with those of QWs. However, we consider that the unique attributes of QWRWs have not been fully utilized in the former studies to obtain deeper or new insights into QWs. In this paper, we (...) highlight the directivity of one-dimensional discrete quantum walks via QWRWs. By exploiting the fact that QWRW allows trajectories of individual walkers to be considered, we first discuss the determination of future directions of QWRWs, through which the effect of linear spreading and localization is manifested in another way. Furthermore, the transition probabilities of QWRWs can also be visualized and show a highly complex shape, representing QWs in a novel way. Moreover, we discuss the first return time to the origin between RWs and QWs, which is made possible via the notion of QWRWs. We observe that the first return time statistics of QWs are quite different from RWs, caused by both the linear spreading and localization properties of QWs. (shrink)

The laser chaos decision maker has been demonstrated to enable ultra-high-speed solutions of multiarmed bandit problems or decision-making in the GHz order. However, the underlying mechanisms are not well understood. In this paper, we analyze the chaotic dynamics inherent in experimentally observed laser chaos time series via surrogate data and further accelerate the decision-making performance via parameter optimization. We first evaluate the negative autocorrelation in a chaotic time series and its impact on decision-making detail. Then, we analyze the decision-making ability (...) using three different surrogate chaos time series to examine the underlying mechanism. We clarify that the negative autocorrelation of laser chaos improves decision-making and that the amplitude distribution of the original laser chaos time series is not optimal. Hence, we introduce a new parameter for adjusting the amplitude distribution of the laser chaos to enhance the decision-making performance. This study provides a new insight into exploiting the supremacy of chaotic dynamics in artificially constructed intelligent systems. (shrink)

How might a human communication system be bootstrapped in the absence of conventional language? We argue that motivated signs play an important role (i.e., signs that are linked to meaning by structural resemblance or by natural association). An experimental study is then reported in which participants try to communicate a range of pre-specified items to a partner using repeated non-linguistic vocalization, repeated gesture, or repeated non-linguistic vocalization plus gesture (but without using their existing language system). Gesture proved more effective (measured (...) by communication success) and more efficient (measured by the time taken to communicate) than non-linguistic vocalization across a range of item categories (emotion, object, and action). Combining gesture and vocalization did not improve performance beyond gesture alone. We experimentally demonstrate that gesture is a more effective means of bootstrapping a human communication system. We argue that gesture outperforms non-linguistic vocalization because it lends itself more naturally to the production of motivated signs. (shrink)

Interest in the computational aspects of modeling has been steadily growing in philosophy of science. This paper aims to advance the discussion by articulating the way in which modeling and computational errors are related and by explaining the significance of error management strategies for the rational reconstruction of scientific practice. To this end, we first characterize the role and nature of modeling error in relation to a recipe for model construction known as Euler’s recipe. We then describe a general model (...) that allows us to assess the quality of numerical solutions in terms of measures of computational errors that are completely interpretable in terms of modeling error. Finally, we emphasize that this type of error analysis involves forms of perturbation analysis that go beyond the basic model-theoretical and statistical/probabilistic tools typically used to characterize the scientific method; this demands that we revise and complement our reconstructive toolbox in a way that can affect our normative image of science.

In this article, I show that the semantics one adopts for mass terms constrains the metaphysical claims one can make about mixtures. I first expose why mixtures challenge a singularist approach based on mereological sums. After discussing an alternative, non-singularist approach, I take chemistry into account and explain how it changes our perspective on these issues.

Several recent contributions to the research on group problem solving suggest that reducing the connectivity between agents in a social network may be epistemically beneficial. This notion stems from the idea that collective problem-solving behavior may benefit from the transient diversity in agents’ beliefs due to increased individual exploration and decreased social influence. At the same time, however, lower connectivity hinders the diffusion of good solutions between network members. Our simulation findings shed light on this trade-off. We identify conditions under (...) which the less-is-more effect is likely to manifest. Our findings suggest that a community consisting of semi-isolated groups could provide an answer to the tension between diversity and diffusion. (shrink)

Sometimes physicians lie to third-party payers in order to grant their patients treatment they would otherwise not receive. This strategy, commonly known as gaming the system, is generally condemned for three reasons. First, it may hurt the patient for the sake of whom gaming was intended. Second, it may hurt other patients. Third, it offends contractual and distributive justice. Hence, gaming is considered to be immoral behavior. This article is an attempt to show that, on the contrary, gaming may sometimes (...) be a physician's duty. Under specific circumstances, gaming may be necessary from the viewpoint of the internal morality of medicine. Moreover, the objections against gaming are examples of what we call the idealistic fallacy, that is, the fallacy of passing judgments in a nonideal world according to ideal standards. Hence, the objections are inconclusive. Gaming is sometimes justified, and may even be required in the name of beneficence. (shrink)

Most people agree that inflicting unnecessary suffering upon animals is wrong. Many fewer people, including among ethicists, agree that painlessly killing animals is necessarily wrong. The most commonly cited reason is that death (without pain, fear, distress) is not bad for them in a way that matters morally, or not as significantly as it does for persons, who are self-conscious, make long-term plans and have preferences about their own future. Animals, at least those that are not persons, lack a morally (...) significant interest in continuing to live. At the same time, some argue that existence itself can be good, insofar as one’s life is worth living. For animals, a good life can offset a quick, if early, death. So, it seems to follow that breeding happy animals that will be (prematurely) killed can be a good thing overall. Insofar as slaughter and sale makes it economically sustainable to raise new ones, who would otherwise not exist, raising and killing animals for food who will have lives worth living is good overall. It benefits them as well as consumers, and makes the world better by adding to the sum of happiness. The process of raising and killing animals with positive welfare produces a sequence of replacement that maintains or increases overall welfare, all else being equal (assuming in particular no overall negative impact on the welfare of other parties). Call this the Replaceability Argument (RA) and the ensuing controversy the Replaceability Problem (RP). This is a problem at the crossroads of the ethics of killing, agricultural ethics, procreation ethics, and population ethics. (shrink)

This book features 20 essays that explore how Latin medieval philosophers and theologians from Anselm to Buridan conceived of habitus, as well as detailed studies of the use of the concept by Augustine and of the reception of the medieval doctrines of habitus in Suàrez and Descartes. Habitus are defined as stable dispositions to act or think in a certain way. This definition was passed down to the medieval thinkers from Aristotle and, to a lesser extent, Augustine, and played a (...) key role in many of the philosophical and theological developments of the time. Written by leading experts in medieval and modern philosophy, the book offers a historical overview that examines the topic in light of recent advances in medieval cognitive psychology and medieval moral theory. Coverage includes such topics as the metaphysics of the soul, the definition of virtue and vice, and the epistemology of self-knowledge. The book also contains an introduction that is the first attempt at a comprehensive survey of the nature and function of habitus in medieval thought. The material will appeal to a wide audience of historians of philosophy and contemporary philosophers. It is relevant as much to the historian of ancient philosophy who wants to track the historical reception of Aristotelian ideas as it is to historians of modern philosophy who would like to study the progressive disappearance of the term “habitus” in the early modern period and the concepts that were substituted for it. In addition, the volume will also be of interest to contemporary philosophers open to historical perspectives in order to renew current trends in cognitive psychology, virtue epistemology, and virtue ethics.

Quantum physics, which offers an explanation of the world on the smallest scale, has fundamental implications that pose a serious challenge to ordinary logic. Particularly counterintuitive is the notion of entanglement, which has been explored for the past 30 years and posits an ubiquitous randomness capable of manifesting itself simultaneously in more than one place. This amazing 'non-locality' is more than just an abstract curiosity or paradox: it has entirely down-to-earth applications in cryptography, serving for example to protect financial information; (...) it also has enabled the demonstration of 'quantum teleportation', whose infinite possibilities even science-fiction writers can scarcely imagine. This delightful and concise exposition does not avoid the deep logical difficulties of quantum physics, but gives the reader the insights needed to appreciate them. From 'Bell's Theorem' to experiments in quantum entanglement, the reader will gain a solid understanding of one of the most fascinating areas of contemporary physics. (shrink)

This paper demonstrates the central role of the Socratic elenchus in the Sophist. In the first part, I defend the position that the Stranger describes the Socratic elenchus in the sixth division of the Sophist. In the second part, I show that the Socratic elenchus is actually used when the Stranger scrutinizes the accounts of being put forward by his predecessors. In the final part, I explain the function of the Socratic elenchus in the argument of the dialogue. By contrast (...) with standard scholarly interpretations, this way of reading the text provides all the puzzles about being (241c4–251a4) with a definite function in the dialogue. It also reveals that Plato’s methodology includes a plurality of method and is more continuous than what is often believed. (shrink)

I defend an account of when and why anger is morally virtuous or vicious. Anger often manifests what we care about; a sports fan gets angry when her favorite team loses because she cares about the team doing well. Anger, I argue, is made morally virtuous or vicious by the underlying care or concern. Anger is virtuous when it manifests moral concern and vicious when it manifests moral indifference or ill will. In defending this view, I reject two common views (...) about anger and moral character. First, I respond to several arguments that attempt to show that all anger is vicious. Then I respond to the view that some anger is required to be a virtuous person. Anger, on my view, can be morally virtuous but is not a necessary condition for being a virtuous person. This best accommodates not only morally irrelevant failures to get angry but also allows for emotional variation among virtuous people. (shrink)

We introduce a logic specifically designed to support reasoning about social choice functions. The logic includes operators to capture strategic ability, and operators to capture agent preferences. We establish a correspondence between formulae in the logic and properties of social choice functions, and show that the logic is expressively complete with respect to social choice functions, i.e., that every social choice function can be characterised as a formula of the logic. We prove that the logic is decidable, and give a (...) complete axiomatization. To demonstrate the value of the logic, we show in particular how it can be applied to the problem of determining whether a social choice function is strategy-proof. (shrink)

“The apocalypse of hope” and other comparable flourishes in the writings of Frantz Fanon and Jean-Paul Sartre on political violence strike an alarming tone. In The Wretched of the Earth, Fanon advocates the way of revolutionary violence as the inevitable consequence of colonialism and its systematic exploitation of colonized natives. In his role of agent provocateur, Sartre’s preface to Fanon’s influential and controversial work characteristically dramatizes this redemptive promise of violence: “to gun down a European is to kill two birds (...) with one stone…there remains a dead man and a free man.” This notorious pronouncement constitutes itself as an act of violence—we must feel threatened—meant to incite the latent counter-violence behind, in Sartre’s diagnosis, the false consciousness of bourgeois toleration and understanding. Could Sartre’s bold statement be spoken today without violent condemnation? This statement claims that, against the dehumanization of colonial oppression, only revolutionary violence allows for the colonized natives to constitute a “people” and recreate themselves in the image of a new humanity forged from the experience of liberation. For Fanon in particular, the recreation of humanity is impossible without the birth of a national consciousness and a revolutionary culture. As Fanon writes, “[w]e believe that the conscious, organized struggle undertaken by a colonized people in order to restore national sovereignty constitutes the greatest cultural manifestation that exists.” This reach toward a new humanism through the praxis of revolutionary violence points directly to the problem of beginnings. As Arendt observes in On Revolution, “[r]evolutions are the only political events which confront us directly and inevitably with the problem of beginning.” Anti-colonial violence, for Fanon, inaugurates the beginning of political life; the colonized native reconstitutes himself as a βίοσ πολιτικόσ capable of both speech and praxis. For Sartre, anti-colonial violence reveals the dialectical necessity of world history in its struggle towards genuine universality and the utopia of a “classless” society. (shrink)

Syllogisms (e.g. “All A are B; All B are C; What is true about A and C?”) are a long‐studied area of human reasoning. Riesterer, Brand, and Ragni compare a variety of models to human performance and show that not only do current models have a lot of room for improvement, but more importantly a large part of this improvement must come from examining individual differences in performance.

Artificial intelligence and robots may progressively take a more and more prominent place in our daily environment. Interestingly, in the study of how humans perceive these artificial entities, science has mainly taken an anthropocentric perspective (i.e., how distant from humans are these agents). Considering people’s fears and expectations from robots and artificial intelligence, they tend to be simultaneously afraid and allured to them, much as they would be to the conceptualisations related to the divine entities (e.g., gods). In two experiments, (...) we investigated the proximity of representation between artificial entities (i.e., artificial intelligence and robots), divine entities and natural entities (i.e., humans and other animals) at both an explicit (Study 1) and an implicit level (Study 2). In the first study, participants evaluated these entities explicitly on positive and negative attitudes. Hierarchical clustering analysis showed that participants’ representation of artificial intelligence, robots and divine entities were similar, while the representation of humans tended to be associated with that of animals. In the second study, participants carried out a word/non-word decision task including religious semantic-related words and neutral words after the presentation of a masked prime referring to divine entities, artificial entities and natural entities (or a control prime). Results showed that after divine and artificial entity primes, participants were faster to identify religious words as words compared to neutral words arguing for a semantic activation. We conclude that people make sense of the new entities by relying on already familiar entities and in the case of artificial intelligence and robots, people appear to draw parallels to divine entities.

The causal view of categories assumes that categories are represented by features and their causal relations. To study the effect of causal knowledge on categorization, researchers have used Bayesian causal models. Within that framework, categorization may be viewed as dependent on a likelihood computation (i.e., the likelihood of an exemplar with a certain combination of features, given the category's causal model) or as a posterior computation (i.e., the probability that the exemplar belongs to the category, given its features). Across three (...) experiments, in combination with computational modeling, we offer evidence that categorization is better accounted for by assuming that people compute posteriors and not likelihoods, though both probabilities are closely related. This result contrasts with existing analyses of causal-based categorization, which assume that likelihood computations give a good approximation of human judgments. We also find that people are able to compute likelihoods in a closely related task that elicits judgments of consistency rather than category membership judgments. Our analyses show that people do use causal probabilistic information as prescribed by a Bayesian model but that they flexibly compute likelihoods or posteriors depending on the task. We discuss our results in relation to the relevant literature on the topic. (shrink)

Within cognitive and developmental psychology, it is commonly argued that perception is the basis for object concepts. According to this view, sensory experiences would translate into concepts thanks to the recognition, correlation and integration of physical attributes. Once attributes are integrated into general patterns, subjects would become able to parse objects into categories. In this article, we critically review the three epistemological perspectives according to which it can be claimed that object concepts depend on perception: state non-conceptualism, content non-conceptualism, and (...) content conceptualism. We show that the three perspectives have problems that make perception inadequate as a conceptual basis. We suggest that the inquiry about the origin and development of object concepts can benefit from a pragmatic perspective that considers objects’ cultural functions as a conceptual foundation. We address this possibility from the theoretical framework of the pragmatics of the object, considering the importance of objects’ functional permanence. (shrink)

We argue that two powerful error-theoretic concepts provide a general framework that satisfactorily accounts for key aspects of the explanation of physical patterns. This method gives an objective criterion to determine which mathematical models in a class of neighboring models are just as good as the exact one. The method also emphasizes that abstraction is essential for explanation and provides a precise conceptual framework that determines whether a given abstraction is explanatorily relevant and justified. Hence, it increases our epistemological understanding (...) of how one should go about reconstructing scientific practices by making clear that, at a fundamental level, a key aspect of mathematical modeling consists in exactly solving nearby problems.

Riesterer and colleagues (...) introduce heuristic rules for predicting NVC and provide directions to modelers on how to up their game. (shrink)

The contention of this paper is that the current ethical debate over embryonic stem cell research is polarised to an extent that is not warranted by the underlying ethical conflict. It is argued that the ethical debate can be rendered more nuanced, and less polarised, by introducing non-binary notions of moral rightness and wrongness. According to the view proposed, embryonic stem cell research—and possibly other controversial activities too—can be considered ‘a little bit right and a little bit wrong’. If this (...) idea were to become widely accepted, the ethical debate would, for conceptual reasons, become less polarised. (shrink)

Human cognition and behavior are dominated by symbol use. This paper examines the social learning strategies that give rise to symbolic communication. Experiment 1 contrasts an individual-level account, based on observational learning and cognitive bias, with an inter-individual account, based on social coordinative learning. Participants played a referential communication game in which they tried to communicate a range of recurring meanings to a partner by drawing, but without using their conventional language. Individual-level learning, via observation and cognitive bias, was sufficient (...) to produce signs that became increasingly effective, efficient, and shared over games. However, breaking a referential precedent eliminated these benefits. The most effective, most efficient, and most shared signs arose when participants could directly interact with their partner, indicating that social coordinative learning is important to the creation of shared symbols. Experiment 2 investigated the contribution of two distinct aspects of social interaction: behavior alignment and concurrent partner feedback. Each played a complementary role in the creation of shared symbols: Behavior alignment primarily drove communication effectiveness, and partner feedback primarily drove the efficiency of the evolved signs. In conclusion, inter-individual social coordinative learning is important to the evolution of effective, efficient, and shared symbols. (shrink)

Based on anthropological fieldwork on the revival of hallucinogen research as well as on the epistemic culture of neurophilosophy, this Common Knowledge guest column examines two very different philosophical engagements with psychedelic drugs. In Thomas Metzinger's evidence-based philosophy of mind, hallucinogens help to operationalize questions about the nature of consciousness. While this project contributes to the great divide between empirically enlightened moderns and tradition-oriented premoderns, Metzinger's neurophilosophical reanimation of the ancient conception of philosophy as cultura animi can build a bridge (...) to Aldous Huxley's perennial philosophy, which has informed the psychedelic intelligentsia like no other body of thought. In the sixteenth century, the philosophia perennis grew out of a decidedly nonmodern philosophy of religion that sought to suture the historical and cultural cracks that would come to define modernity. This essay argues that neurophilosophy and ethnographic studies of consciousness cultures could function as critical correctives in a contemporary rearticulation of perennial philosophy. (shrink)

ABSTRACT This paper examines consequences of the computer revolution in mathematics. By comparing its repercussions with those of conceptual developments that unfolded in the nineteenth century, I argue that the key epistemological lesson to draw from the two transformative periods is that effective and successful mathematical practices in science result from integrating the computational and conceptual styles of mathematics, and not that one of the two styles of mathematical reasoning is superior. Finally, I show that the methodology deployed by applied (...) mathematicians in modern scientific computing is a paradigmatic instance of this key lesson. (shrink)

Despite intensive exegetical work, Plato’s description of dialectic in the Sophist still raises many questions. Through a close reading of this passage that contextualizes it in the general organisation of the Sophist, this paper provides answers to these questions. After presenting the difficult text, I contend that the “vowel-kinds” are necessary conditions for the blending of kinds. Then, I interpret the “cause of divisions” mentioned by the Stranger as the kinds responsible of the dichotomous division in the first half of (...) the dialogue. In the next part, I show that 235d5-e2 does not describe a procedure of “meta-divison” as some commentators have it, but that it describes the method of division itself. Finally, I connect the difficulty and the obscurity of the passage to the fact that dialectic is the supreme science and I explain why dialectic is the science of free men. (shrink)

In the 20th century, the boundaries of psychosis emerged as an area in which psychiatric judgement faced numerous and profound uncertainties. Between obvious neuroses and personality and reactive disorders on the one hand, and unquestionable psychoses on the other, psychiatrists faced a world of suspected cases of schizophrenia, doubtful personality disorder diagnoses or probable cases of psychosis constituting a garden of equivocal clinical presentations in which both individual psychiatrists and the discipline as a whole were confronted with the limits of (...) their knowledge. This article examines how psychiatrists from two German university clinics managed the multiple uncertainties involved in diagnosing cases of early psychosis between 1950 and 1980. Based on the analysis of a sample of records, we propose a pragmatic interpretation of the ways in which these uncertainties were recorded by psychiatrists. How were uncertainties and doubts expressed in the records and managed by clinicians? What means were used to dispel doubt? What were the consequences for patients of these diagnostic uncertainties? The article defines an uncertainty diagnosis as a diagnosis expressed with reservations by its author and recorded as such in a medical file. Depending on the nature of the uncertainty, the types of evidence used by the professionals and how this evidence was dealt with, we have identified three types of uncertainty diagnoses: suspicion, plausibility and probability diagnoses. The article then reflects on the role of the patients themselves in shaping these uncertain situations. (shrink)

“'Ontological Mislocations', Modes of Conciousness and History: Indiscernibles, Displacement and Horizons of Possibility in the Philosophy of Arthur Danto”. In this article my purpose is to trace the links between three key elements in Arthur Danto’s philosophy: first, the capital consideration, for philosophical purposes, of human beings as ens representans , departing from the elucidation of a type of cognitive episode that Danto called “basic”. Secondly,I am concerned with the recurring appeal to a plane of consciousness that supports a dual (...) characterization in terms of the pair inside/outside and enables alogical space that is characteristic of philosophy as a reflective mode. Finally, I will treat a form of cognitive failure that Danto considered fundamental to the philosophical perspective, which leads to a specific type of restructuring of our ordinary system of beliefs. What I contend is that in Danto’s philosophical system these three elements become intelligible from the postulation of an effectual background that the author calls “objective historical structure”, which is characterized in terms of the horizons of possibility and impossibility that it delineates. These figures of historical-temporal possibility and impossibility constitute the matrix of historicity itself and also contribute decisively to shaping the permanent nucleus of dantean philosophical concerns.

Religion and spirituality seem to be very important for HIV-positive patients believers. Indeed, a recurring number of studies show strong correlations between religiosity/spirituality of individuals and different dimensions of health. The majority of these studies show most positive associations of religiosity/spirituality to physical health through reducing emotional distress, reduced rates of depression, greater optimism, better psychological adjustment, better preservation of CD4 cells, better control of viral load. The objective of this research is to understand the nature of the relationship between (...) religiosity and emotional health among HIV-positive patients, migrants from sub-Saharan Africa. Religiosity, the frequency of depressive episodes and subjective health 81 asymptomatic HIV patients regularly followed, were evaluated.

Information about the powers and abilities of acting entities is used to coordinate their actions in societies, either physical or digital. Yet, the commonsensical meaning of an acting entity being deemed able to do something is still missing from the existing specification languages for the web or for multi-agent systems. We advance a general purpose abstract logical account of evidence-based ability. A basic model can be thought of as the ongoing trace of a multi-agent system. Every state records systemic confirmations (...) and disconfirmations of whether an acting entity is able to bring about something. Qualitative inductive reasoning is then used in order to infer what acting entities are deemed able to bring about in the multi-agent system. A temporalised modal language is used to talk about deemed ability, actual agency, and confirmation and disconfirmation of deemed ability. What constitutes a confirmation and a disconfirmation is left to the modeller as in general it depends on the application at hand. So to illustrate the methodology we propose two extended examples, one in practical philosophy, the other in system engineering. We first use a logic of agency and ability to obtain a version of Mele’s general practical abilities. Then, we look at the management of abilities in a supervised system. (shrink)

We may well be witnessing a decisive event in the history of knowledge as diversity is becoming one of the premier values of late modern societies. We seek to preserve and foster biodiversity, neurodiversity, racial diversity, ethnic diversity, gender diversity, linguistic diversity, cultural diversity, and perspectival diversity. Perspectival diversity has become the passage point through which other forms of diversity must pass to become epistemically consequential. This article examines how two of its varieties, viewpoint diversity and educational diversity, have come (...) to transform the moral economy of science. Both aim at multiplying perspectives on a given subject, but their political subtexts differ markedly. The valorization of educational diversity followed a US Supreme Court decision in 1978 that enabled universities to advance social justice, if they justified race-conscious admissions in terms of the pedagogic benefits of a more diverse student body for all. By contrast, the proponents of viewpoint diversity aim at the reform of scientific knowledge production and distribution rather than the reallocation of status and power among different social groups. We examine the political epistemology of viewpoint diversity by analyzing a controversy between social psychologists who, amid the American culture wars of the 2010s, debated how to rein in their political biases in a scientific field supposedly lacking political diversity. Out of this scientific controversy grew Heterodox Academy, an activist organization promoting viewpoint diversity in higher education. By relating and comparing viewpoint and educational diversity, we clarify what is at stake epistemically in the US-centric moral economy of diversity. (shrink)

Dans son dernier cours au Collège de France, Michel Foucault nous parle d'un oubli, plus fondamental à ses yeux que le fameux "oubli de l'être", ou plus précisément d'une négligence ; une négligence dont la philosophie est responsable, ce qui est d'autant plus paradoxal qu'il concerne précisément la vie philosophique. "Je voudrais, en tout cas, suggérer simplement que s'il est vrai que la question de l'être a bien été ce que la philosophie occidentale a oublié et dont l'oubli a rendu (...) possible la métaphysique, peut-être aussi la question de la vie philosophique n'a-t-elle pas cessé d'être, je ne dirais pas oubliée, mais négligée ; elle n'a pas cessé d'apparaître comme en trop par rapport à la philosophie, à la pratique philosophique, à un discours de plus en plus indexé au modèle scientifique" Cette négligence a une histoire. Car le problème de la vie philosophique a été posé dans toute sa radicalité dans l'Antiquité ; il n'était pas complètement oublié à l'époque moderne, comme en témoigne l'oeuvre de Spinoza ; mais à partir du moment "où la philosophie est devenue un métier de professeur, c'est-à-dire au début du XIXème siècle", elle a évacué du champ des problèmes pertinents, des problèmes "sérieux", cela même qui pourtant lui avait donné son horizon et sa raison d'être : la possibilité de définir une vie philosophique, c'est-à-dire une vie juste, une vie bonne, une "vraie vie".

In this paper, I offer a novel reconstruction of Hegel’s argument for his mysterious claim that “self-consciousness is desire itself.” In section I, I motivate two interpretive constraints, which I refer to as the practicality constraint and the continuity constraint. According to the former, the kind of desire that Hegel argues is a necessary condition of self-consciousness involves a practical (and so not merely theoretical or contemplative) relation between subject and object. According to the latter, Hegel’s argument takes as its (...) sole starting point a shape of consciousness that has itself as object or, as Hegel puts it, a shape that consists in “a distinguishing of what is not distinct.” I argue that recent influential interpretations openly or tacitly violate either the practicality constraint or the continuity constraint. In section II, I piece together my own, alternative interpretation of Hegel’s argument, which heeds the two constraints in a way that fits Hegel’s text more closely than do other interpretations. I thus hope to shed new light on Hegel’s view that the I or consciousness can have itself as its object only if it also relates to external objects in a desirous, destructive way. (shrink)

What is a uterus to a woman and to society? This article calls for a holistic reevaluation of how we perceive and what we expect from women’s uteruses. We explore the powerful and deeply rooted cultural representations of women’s uteruses as mere receptacles and the impact of such representations on biological categories, medical practices, and current policies. Considering controversies surrounding hysterectomies, cesarean sections, and uterus transplants, we elucidate ambivalent narratives that either promote an essentialist approach where the uterus is emblematic (...) of womanhood, or imply that the uterus is a dispensable organ useless outside of reproduction.
