A critical, philosophical engagement of the psychological structures that propagate the continued oppression of women. In this book, the Italian feminist thinker Lea Melandri argues that systemic violence against women has deep psychoanalytic roots. Drawing inspiration from the work of Freud and the psychiatrist and psychoanalyst Elvio Fachinelli, along with feminist practices of consciousness-raising, Melandri demonstrates how male dominance and female subservience are established by society through a binary and oppositional understanding of sex and gender. This understanding—and the oppression and (...) violence against women that results—is inscribed in the psyches of both men and women, and is replicated anew from generation to generation. Melandri analyzes women in media, politics, philosophy, and literature to show how this plays out, and calls for awareness of these deep psychic structures and expectations formed within the dynamics of society and primary family relations. Lea Melandri is one of Italy’s best-known feminist thinkers and activists. She is the author of many books and continues to write and advocate for women’s rights. In 2012, she was awarded by the city of Milan the Ambrogino d’oro, one of the city’s highest honors. Antonio Calcagno is Professor of Philosophy at King’s University College at Western University, Canada.

This article explores the justification of states' territorial rights. It starts by introducing three questions that all current theories of territorial rights attempt to answer: how to justify the right to settle, the right to exclude, and the right to settle and exclude with reference to a particular territory. It proposes a ‘permissive’ theory of territorial rights, arguing that the citizens of each state are entitled to the particular territory they collectively occupy, if and only if they are also politically (...) committed to the establishment of a global political authority realizing just reciprocal relations. The article is developed by introducing some key features of the permissive theory and by explaining how such an account addresses the questions of settlement, exclusion and particularity in ways that significantly improve on existing rival accounts (most prominently: acquisition theories, legitimacy-based theories and nationalist theories).

Global Justice and Avant-Garde Political Agency offers a fresh, nuanced example of political theory in an activist mode. Setting the debate on global justice in the context of recent methodological disputes on the relationship between ideal and nonideal theorizing, Ypi's dialectical account shows how principles and agency really can interact.

Scholarship on Plato's Timaeus has paid relatively little attention to Tim. 77a–81, a seemingly disjointed passage on topics including plants, respiration, blood circulation, and musical sounds. Despite this comparative neglect, commentators both ancient and modern have levelled a number of serious charges against Timaeus' remarks in the passage, questioning the coherence and explanatory power of what they take to be a theory of respiration. In this paper, I argue that the project of 77a–81e is not to sketch theories of respiration, (...) circulation, and digestion, but to explain how the human body is maintained in light of and despite constant environmental depletion. Further, I argue that in order to understand this account of “the replenishing system,” we need to understand Timaeus' striking analogy of the fish trap or nassa. Commentators have generally focused directly on the workings of the bodily construction that Timaeus likens to a fish trap, but without considering how we should understand the analogy qua analogy. I develop a functional reading of the analogy that yields a coherent account of the replenishing system on which previous criticisms of Timaeus' remarks on respiration do not arise. Aside from lending greater unity to the passage, both internally and within its immediate context in the dialogue, this account of the replenishing system contributes to our understanding of Timaeus' reason-and-necessity explanatory framework as applied to the human body and has noteworthy implications for specific explanatory principles, in particular like-to-like motion and circular thrust.

Is it possible to justify territorial rights? Provided a justification for territorial rights can be found, does it ground claims toparticularterritories? And provided a claim to particular territories can be justified, what kind of claim is it? Is it a claim to jurisdiction? A claim to control resources? A claim to control the movement of people across borders? In this paper I review some prominent accounts seeking to answer these questions. After outlining their main features, I focus on some difficulties (...) they encounter, in particular with regard to the justification of exclusion. (shrink)

Is personal moral inconsistency a challenge to overcome or embrace? This paper opts for the latter and argues for the Virtue of Encompassing the Contrary (VEC). According to VEC, an individual can balance and realize opposite values or virtues through time virtuously. This paper discusses critically various explanations given for moral inconsistency: Circumstantial Relativism, Moral Opportunism, the Consequentialist Solution, Moral Ambivalence, Kant’s Imperfect Duty and Dancy’s Moral Particularism. The paper argues that VEC fares better in answering the moral challenge of (...) inconsistent behavior. (shrink)

In clinical practice, evidence suggests that teaching ethics using normative ethical theory has little influence on the ethical actions of providers in practice. Thus, new training methods are needed that improve clinician response to ethical problems. A sensemaking approach to ethics training has demonstrated promise as an evidence-based pedagogical method to improve ethical reasoning and response. Project ECHO is theoretically linked to improved sensemaking. This study examines the effectiveness of ECHO and training in use of sensemaking approaches to ethical response (...) by clinicians. A quasi-experimental design study using univariate linear regression was used to examine the effect of the three types of ethics training on ethical response self-efficacy scores, while controlling for participant characteristics of years in practice, discipline and sex. We found evidence that training in sensemaking through participation in ECHO promotes improved ethical response self-efficacy of clinicians. However, results also suggest that a traditional ECHO format that does not explicitly introduce sensemaking strategies into the training does not result in the same learning outcomes as measured through an ethical response self-efficacy survey. This study found important preliminary results to support use of sensemaking approaches in clinical ethics training. (shrink)

Suppose that the following describes an intelligible scenario. A subject is wired up to another's body in such a way that she has bodily experiences ‘as from the inside’ caused by states and events in the other body, that are subjectively indistinguishable from ordinary somatosensory perception of her own body. The supposed intelligibility of such so-called crossed wire cases constitutes a significant challenge to the claim that our somatosensory judgements are immune to error through misidentification relative to uses of the (...) first person pronoun. After all, the subject in this case is liable to commit precisely the sort of error ruled out by such a claim. In this paper I argue that the proponent of this challenge must establish at least two things: that the subject is committing an error of misidentification, and that her judgement shares its epistemic grounds with our ordinary somatosensory judgements. Neither condition, I argue, can be reached from the stipulations permitted into the starting descriptions of the cases. (shrink)

This essay compares the thoughts of Kant and Marx on revolution. It focuses in particular on two issues: the contribution of revolutionary enthusiasm to the cause of emancipatory political agents and its educative role in illustrating the possibility of progress for future generations. In both cases, it is argued, the defence of revolution is offered in the context of illustrating the possibility of moral progress for the species, even if not for individual human beings, and brings out the centrality of (...) collective agency in moving toward universal moral goals. Discussing the implications of these points is of significant historical interest: it allows us to defend an interpretation of Kant’s political thought which is sensitive to the material conditions of historical development and to rescue Marx from an amoral reading of his philosophy of history. Reflecting on the role and preconditions of transformative collective agency is also of normative interest: it allows us to better evaluate the significance of political events that, firstly, re-shape the boundaries of political feasibility and, secondly, play a crucial educative role in motivating future progressive initiatives.

This paper comments on Richard Bourke's Hegel and World Revolutions, focusing on its analysis of Hegel's relevance for debates on revolution, freedom, and the Enlightenment. While agreeing with Bourke's call for critically engaging with Hegel's ideas rather than dismissing them outright, the paper raises some questions concerning Bourke's reconstruction of Hegel's interpretation of Kant, his account of the French Revolution, and the impact of Hegel's work on contemporary debates.

This article explores the tensions between cosmopolitanism and sovereignty as a means to conceptualize the ethics of European foreign policy. It starts by discussing the claim that, in order for the EU to play a meaningful role as an international actor, a definition of the common ethical values orienting its political conduct is required. The question of a European federation of states and its ethical conceptualization emerges clearly in some of the philosophical writings of the 17th and 18th centuries. I (...) seek to provide an outline of the main arguments presented by authors such as Saint Pierre, Rousseau and Kant regarding the implications of the emerging difference between cosmopolitanism and the law of nations in the ethics of international relations. The article focuses on the normative significance of the concept of sovereignty as it emerges in modern political philosophy and highlights its tensions with the ideas of moral and political cosmopolitanism. This exploration serves a double function: theoretical and practical. From the theoretical perspective it leads to a better understanding of the tensions involved in conceptualizing a common ethical orientation for the states of Europe. From the practical standpoint it sheds light on some persistent difficulties the European Union faces in trying to move beyond an intergovernmental political arrangement in the field of foreign policy.

The “happy fish” passage concluding the “Autumn Floods” chapter of the Classical Chinese text known as the Zhuangzi has traditionally been seen to advance a form of relativism which precludes objectivity. My aim in this paper is to question this view with close reference to the passage itself. I further argue that the central concern of the two philosophical personae in the passage – Zhuangzi and Huizi – is not with the epistemic standards of human judgements (the established view since (...) Hansen, “The Relatively Happy Fish”), but with the more basic problem of species-specific perspectives. On my reading, Zhuangzi’s emphatic positionality in the passage – on the dam, accompanied by his friend Huizi – plausibly suggests a circumspect reflection on the limitedness of human knowledge. It is significant that Zhuangzi’s knowledge of fish happiness is avowedly from a certain place, and not absolute. But there is still a sense in which this view is objective: namely, insofar as it adequately accounts for an inherently human perspective on the world. I call this modest form of relativism ‘Species Relativism’, which, crucially, leaves room for objectivity, even though a fully objective (i.e. absolute) view of the world is not accessible to humans.

This book focuses on a question issued from The Architectonic of Pure Reason, one of the most important sections of Kant's first Critique: what is the human being? It suggests that the answer to this question is tied to a particular account of the unity of reason - one that stresses its purposive character.

This paper brings into focus the idea that just as no third-personal way of thinking could capture the self-consciousness of first-person thought, no first- or third- personal way of thinking could capture the especially intimate way we have of relating to each other canonically expressed with our uses of ‘you’. It proposes, motivates and defends the view that second-person speech is canonically expressive of a distinctive way we have of thinking of each other, under a concept that refers de jure (...) to its addressee and whose availability depends on standing in a relation of interpersonal self-consciousness with another.

Partnerships can play an important role in addressing environmental concerns and fostering environmental improvement. In this context, we argue that a more elaborate understanding is needed of how partners intend to reach beyond the partnership boundaries and target stakeholders at the firm, industry, supply-chain, or societal levels. As environmental improvement is intertwined with the process of change, we build on the theory of planned change to explain how the focus on selected partnership mechanisms may help partners anticipate and overcome barriers (...) when targeting environmental improvement at these different levels. We test our framework, using a sample of 566 environmental partnerships formed in the USA, and provide rich insights into how partners intend to reach beyond the partnership boundaries. From a practical perspective, these insights may inform corporate managers’ decision to configure environmental partnerships in terms of the target group and suitable partnership mechanism. From a theory perspective, the study helps develop a more systematic understanding of what partners intend to do and when partnerships may provide benefits in addressing level-specific change barriers. These insights provide a first step in positioning partnerships in the broader context of environmental change and encourage future research to move from the intentions to the actual outcomes.

Do we think in a language-like format? Taking the marker of language-like formats to be the property of unconstrained systematicity, this paper considers the following master argument for the claim that we do: language is unconstrainedly systematic, if language is unconstrainedly systematic then so is thought, so thought is unconstrainedly systematic. It is easy to feel that there is something right about this argument, that there will be some way of filling in its details that will vindicate the idea that (...) our thought must be unconstrainedly systematic given that the language in which we express it is. Clearly, however, the second premise needs support—we need a principled reason for moving from the unconstrained systematicity of language to the unconstrained systematicity of thought. This paper gives three passes at formulating such a principle. This turns out to be much harder than it might seem. We should, I conclude, resist falling too easily for the lure of this master argument for the language-like format of thought. (shrink)

The move to remote learning during COVID-19 has impacted billions of students. While research shows that school closure, and the pandemic more generally, has led to student distress, the possibility that these disruptions can also prompt growth in is a worthwhile question to investigate. The current study examined stress-related growth (SRG) in a sample of students returning to campus after a period of COVID-19 remote learning (n= 404, age = 13–18). The degree to which well-being skills were taught at school (...) (i.e., positive education) before the COVID-19 outbreak and student levels of SRG upon returning to campus was testedviastructural equation modeling. Positive reappraisal, emotional processing, and strengths use in students were examined as mediators. The model provided a good fit [χ2= 5.37,df= 3,p= 0.146, RMSEA = 0.044 (90% CI = 0.00–0.10), SRMR = 0.012, CFI = 99, TLI = 0.99] with 56% of the variance in SRG explained. Positive education explained 15% of the variance in cognitive reappraisal, 7% in emotional processing, and 16% in student strengths use during remote learning. The results are discussed using a positive education paradigm with implications for teaching well-being skills at school to foster growth through adversity and assist in times of crisis. (shrink)

The ?values of sport? is a concept that is often used to justify actions and policies by a range of agents and agencies from coaches and teachers to governing bodies and educational institutions. From a philosophical point of view, these values deserve to be analysed with great care to make sure we understand their nature and reach. The aim of this paper is to critically examine the values carried by the educational conception of sport that Pierre de Coubertin developed and (...) to see how they relate to certain values in the philosophy of Friedrich Nietzsche. To be able to understand in depth the moral construct of de Coubertin's system, it is essential to delve into the entire system he builds in order to develop athletic participants closer to his ideal of what a human should be. This in turn rests on his conception of Man, which is comprised of body, spirit and character. An understanding of his structure opens the way to a broader awareness of de Coubertin's educational system, of which sport was only part. We will then see that the values are a consequence of this pedagogical search for the ideal human. It is argued that this ideal of a human is similar to the one described by Nietzsche as the Übermensch . A philosophical case study is conducted, taking as its object the story of the first recipient of the Pierre de Coubertin medal, which rewards fair play among Olympic competitors. Judging the story through Nietzschean eyes allows for his thoughts to be put into practice. His lesser-known texts such as Homer and Competition on the emulation of creative powers shed light on today's sports. Concepts such as guilt, excellence, will to power and effectiveness help us compare these two authors and understand that competition is not necessarily about dominating others, but more about generating human excellence.

There is a need to explore educational strategies that translate ethics knowledge into ethical behavior. Commonly used pedagogical approaches steeped in traditional normative ethical theory are less powerful than sensemaking in preparing clinicians to respond to ethical problems in practice. This integrative review of 15 articles explores the use of sensemaking as an instructional method for clinical ethics. Whittemore and Knafl’s :546–553, 2005) integrative review method guided a systematic appraisal of data from both qualitative and quantitative research traditions, synthesizing disparate (...) studies in analyzing literature about the use of sensemaking as a pedagogical approach in teaching ethics. Findings supported the use of Weick’s sensemaking theory to develop instructional methods that encourage ethical decision making in students as well as promote ethical response by health care providers. The review reveals important theoretical and training implications for introducing sensemaking as a means to promote ethical action in clinical practice. (shrink)

Libertarians often invoke the principle of self-ownership to discredit distributive interventions authorized by the more-than-minimal state. But if one takes a democratic approach to the justification of ownership claims, including claims of ownership over oneself, the validity of the self-ownership principle is theoretically inseparable from the normative justification of the state. Since the idea of the state is essential to the very assertion (not just the positive enforcement) of the principle of self-ownership, invoking the principle to discredit a distribution of (...) ownership authorized by the state commits libertarians also to weakening that principle's validity. Put differently, appealing to the self-ownership principle to circumscribe the state's power to distribute property is problematic when the state is necessary to assert the validity of that principle. This is because anytime the self-ownership principle is used to undermine a state-based distribution of property it is also implicitly eroding the ground for asserting its own validity.1. (shrink)

Models of category learning have been extensively studied in cognitive science and primarily tested on perceptual abstractions or artificial stimuli. In this paper, we focus on categories acquired from natural language stimuli, that is, words. We present a Bayesian model that, unlike previous work, learns both categories and their features in a single process. We model category induction as two interrelated subproblems: the acquisition of features that discriminate among categories, and the grouping of concepts into categories based on those features. (...) Our model learns categories incrementally using particle filters, a sequential Monte Carlo method commonly used for approximate probabilistic inference that sequentially integrates newly observed data and can be viewed as a plausible mechanism for human learning. Experimental results show that our incremental learner obtains meaningful categories which yield a closer fit to behavioral data compared to related models while at the same time acquiring features which characterize the learned categories.

This paper makes the case for amnesty of irregular migrants by reflecting on the conditions under which a wrong that is done in the past can be considered superseded. It explores the relation between historical injustice and irregular migration and suggests that we should hold states to the same stringent standards of compliance with just norms that they apply to the assessment of the moral conduct of individual migrants. It concludes that those standards ought to orient migrants and citizens’ moral (...) assessment of how their states handle questions of irregular migration and to inform political initiatives compatible with these moral assessments.

It is widely believed that the ancient Greeks thought that Thales was the first philosopher, and that they therefore maintained that philosophy had a Greek origin. This paper challenges these assumptions, arguing that most ancient Greek thinkers who expressed views about the history and development of philosophy rejected both positions. I argue that not even Aristotle presented Thales as the first philosopher, and that doing so would have undermined his philosophical commitments and interests. Beyond Aristotle, the view that Thales was (...) the first philosopher is attested almost nowhere in antiquity. In the classical, Hellenistic, and post-Hellenistic periods, we witness a marked tendency to locate the beginning of philosophy in a time going back further than Thales. Remarkably, ancient Greek thinkers most often traced the origins of philosophy to earlier non-Greek peoples. Contrary to the received view, then, I argue that (1) vanishingly few Greek writers pronounced Thales the first philosopher; and (2) most Greek thinkers did not even advocate a Greek origin of philosophy. Finally, I show that the view that philosophy originated with Thales (along with its misleading attribution to the Greeks in general) has roots in problematic, and in some cases manifestly racist, eighteenth-century historiography of philosophy.

L’intérêt public est au cœur de la sémantique politique : le syntagme est omniprésent dans les pratiques discursives du droit et de l’administration publics ainsi que dans les discours rhétoriques et polémiques des acteurs du débat public. Pourtant, s’il constitue un élément de langage fondamental, son contenu a rarement été défini : ce sont les usages à travers le temps qui peuvent en indiquer le sens, mais ce sens, pour n’avoir pas été explicitement posé, demeure nécessairement incertain et peut varier (...) selon les contextes, les énonciateurs et les destinataires à qui il est adressé.La difficulté sémantique tient à l’apposition quasiment oxymorique du terme d’« intérêt » – qui, logiquement, devrait être relatif à chaque individu – et de celui de « public » uni, uniforme et homogène. Sur quel fondement comment peut-on dégager un contenu objectif à l’expression? Peut-il être suffisamment précis et solide pour être le fondement de la légitimité politique, peut-il être le critère pour déterminer si la réalisation d’une politique publique est justifiée ou pas? L’imprécision sémantique empêche-t-elle d’établir l’existence d’un concept politique d’intérêt commun? C’est donc le statut épistémologique de l’intérêt public qu’il convient de questionner in fine : il nous faut déterminer de quel type d’objet épistémologique il s’agit pour saisir à quelles fins il est manipulé dans les pratiques discursives. Il s’agira dans cet article de développer la thèse selon laquelle l’intérêt public n’est pas un concept scientifique à proprement parler, ni une catégorie, ni même une expérience politique pure, il est éventuellement un concept au sens politique du terme, à comprendre comme une structure langagière, une fiction régulatrice toujours en cours de formation, historiquement élaborée en réponse à une anthropologie rationnelle. Pour cela, on mettra en évidence, dans un premier moment, l’absence de définition du prétendu concept d’intérêt public. Dans un second temps, nous expliquerons sa persistance paradoxale non seulement dans les discours politiques mais aussi dans les discours théoriques en revenant sur les étapes les plus importantes de la généalogie du concept. Finalement, nous pourrons développer les difficultés que suppose la qualification épistémologique de la notion « d’intérêt public » et proposer une interprétation de son statut. (shrink)

In this paper I discuss the managerial template that has become the normative model for the organization of the university. In the first part of the paper I explain the corporatization of academic life in terms of the functional relationships that make up the organizational components of the commercial enterprise and their inappropriateness for the life of the academy. Although there is at present a significant body of literature devoted to this issue, the goal of this paper is to explain (...) the genesis of this phenomenon through a reference to the ideology that characterizes our modern secular age. This is the subject of the second part of the paper. Most texts seek to explain this ideological development either through the ever increasing dominance of economic rationalism, perceived conservatism of collegial forms of governance, the necessity to transfer fiscal responsibility in tight budgetary periods, the decline of the Keynesian ‘welfare consensus’, or the legacy of the power regimes that began to take shape in the liberal societies of the 19th century. I trace this development to the beginnings of Modernity and the Cartesian bifurcation that separated the material world from its spiritual and intellectual source and thereby overthrew the hierarchy of related values that informed both nature and human organization. In articulating this argument I make reference to the thought of Jacques Maritain, Charles Taylor and René Guénon. (shrink)

Les programmes d’accompagnement des chômeurs peuvent se lire comme un temps prescrit institutionnellement, mesuré, optimisé, et moins orienté vers la sortie du chômage que vers la réhabilitation de l’employabilité.

Why are people interested in money? Specifically, what could be the biological basis for the extraordinary incentive and reinforcing power of money, which seems to be unique to the human species? We identify two ways in which a commodity which is of no biological significance in itself can become a strong motivator. The first is if it is used as a tool, and by a metaphorical extension this is often applied to money: it is used instrumentally, in order to obtain (...) biologically relevant incentives. Second, substances can be strong motivators because they imitate the action of natural incentives but do not produce the fitness gains for which those incentives are instinctively sought. The classic examples of this process are psychoactive drugs, but we argue that the drug concept can also be extended metaphorically to provide an account of money motivation. From a review of theoretical and empirical literature about money, we conclude that (i) there are a number of phenomena that cannot be accounted for by a pure Tool Theory of money motivation; (ii) supplementing Tool Theory with a Drug Theory enables the anomalous phenomena to be explained; and (iii) the human instincts that, according to a Drug Theory, money parasitizes include trading (derived from reciprocal altruism) and object play.
