The planetary boundaries concept has profoundly changed the vocabulary and representation of global environmental issues. The article starts by highlighting the strengths and weaknesses of planetary boundaries from a social science perspective. It is argued that the growth imperative of capitalist economies, as well as other particular characteristics detailed below, are the main drivers of the ecological crisis and exacerbated trends already underway. Further, the planetary boundaries framework can support interpretations that do not solely emphasize technocratic operational approaches and costs, (...) but also assume that these alone can be the solution.

The notion of societal boundaries aims to enhance the debate on planetary boundaries. The focus is on capitalist societies as a heuristic for discussing the expansionary dynamics, power relations, and lock-ins of modern societies that impel highly unsustainable societal relations with nature. While formulating societal boundaries implies a controversial process – based on normative judgments, ethical concerns, and socio-political struggles – it has the potential to offer guidelines for a just, social-ecological transformation.

A semantics of pictorial representation should provide an account of how pictorial signs are associated with the contents they express. Unlike the familiar semantics of spoken languages, this problem has a distinctively spatial cast for depiction. Pictures themselves are two-dimensional artifacts, and their contents take the form of pictorial spaces, perspectival arrangements of objects and properties in three dimensions. A basic challenge is to explain how pictures are associated with the particular pictorial spaces they express. Inspiration here comes from recent (...) proposals that analyze depiction in terms of geometrical projection. In this essay, I will argue that, for a central class of pictures, the projection-based theory of depiction provides the best explanation for how pictures express pictorial spaces, while rival perceptual and resemblance theories fall short. Since the composition of pictorial space is itself the basis for all other aspects of pictorial content, the proposal provides a natural foundation for further pictorial semantics. (shrink)

What is it for a picture to depict a scene? The most orthodox philosophical theory of pictorial representation holds that depiction is grounded in resemblance. A picture represents a scene in virtue of being similar to that scene in certain ways. This essay presents evidence against this claim: curvilinear perspective is one common style of depiction in which successful pictorial representation depends as much on a picture's systematic differences with the scene depicted as on the similarities; it cannot be analyzed (...) in terms of similarity alone. The same problem arises for many other kinds of depiction. The essay concludes that depiction in general is not grounded in resemblance but geometrical transformation. (shrink)

It is common to distinguish two great families of representation. Symbolic representations include logical and mathematical symbols, words, and complex linguistic expressions. Iconic representations include dials, diagrams, maps, pictures, 3-dimensional models, and depictive gestures. This essay describes and motivates a new way of distinguishing iconic from symbolic representation. It locates the difference not in the signs themselves, nor in the contents they express, but in the semantic rules by which signs are associated with contents. The two kinds of rule have (...) divergent forms, occupying opposite poles on a spectrum of naturalness. Symbolic rules are composed entirely of primitive juxtapositions of sign types with contents, while iconic rules determine contents entirely by uniform natural relations with sign types. This distinction is marked explicitly in the formal semantics of familiar sign systems, both for atomic first-order representations, like words, pixel colors, and dials, and for complex second-order representations, like sentences, diagrams, and pictures.

Those who wish to claim that all facts about grounding are themselves grounded (“the meta-grounding thesis”) must defend against the charge that such a claim leads to infinite regress and violates the well-foundedness of ground. In this paper, we defend. First, we explore three distinct but related notions of “well-founded”, which are often conflated, and three corresponding notions of infinite regress. We explore the entailment relations between these notions. We conclude that the meta-grounding thesis need not lead to tension with (...) any of the three notions of “well-founded”. Finally, we explore the details of and motivations for further conditions on ground that one might add to generate a conflict between the meta-grounding thesis and a well-founded constraint. We explore these topics by developing and utilizing a formal framework based on the notion of a grounding structure. (shrink)

This Special Issue collects five articles that are located in the present global context, and draw on methods from across critical discourse studies (CDS) to examine the interaction between material realities of climate change and discursive communication between different Parties and non-Party stakeholders in multimodal ways and on multiple platforms. To this end, it draws on discourses such as the UN speeches, UN documents, EU green deal policy, official documents submitted by African countries to the United Nations Framework Convention on (...) Climate Change (UNFCCC), and news reports in China and Australia. In these studies, diverse social and linguistic concepts were utilized and revisited to better inform the use of linguistic and/or visual symbols in different types of public discourse. This Special Issue aims to take the field a step further by showing the importance of carrying out more international research to expand our knowledge of the global, regional, and local discourse and ideologies that shape what we come to know and understand as climate change and how it is to be addressed. We envisage it will bring significant theoretical, methodological, and empirical insights into the relations between language use, discursive practice, and social practice. (shrink)

Groups are ubiquitous in our lives. But while some of them are highly structured and appear to support a shared intentionality and even a shared agency, others are much less cohesive and do not seem to demand much of their individual members. Queues, for example, seem to be, at a given time, nothing over and above some individuals as they exemplify a certain spatial arrangement. Indeed, the main aim of this paper is to develop the more general thought that at (...) a given time, a group is nothing over and above some individual members as they exemplify a certain complex condition. The general conception of groups that emerges is able to accommodate a variety of constraints on a reasonable answer to the question of what are groups. (shrink)

Ground offers the hope of vindicating and illuminating an classic philosophical idea: the layered conception, according to which reality is structured by relations of dependence, with physical phenomena on the bottom, upon which chemistry, then biology, and psychology reside. However, ground can only make good on this promise if it is appropriately formally behaved. The paradigm of good formal behavior can be found in the currently dominant grounding orthodoxy, which holds that ground is transitive, antisymmetric, irreflexive, and foundational. However, heretics (...) have recently challenged the orthodoxy. In this paper, I examine ground’s ability to vindicate the layered conception upon various relaxations of the orthodox assumptions. I argue that highly unorthodox views of ground can still vindicate the layered conception and that, in some ways, the heretical views enable ground to better serve as a guide to reality’s layering than do orthodox views of ground.

Philosophers often explain what could be the case in terms of what is, in fact, the case at one possible world or another. They may differ in what they take possible worlds to be or in their gloss of what is for something to be the case at a possible world. Still, they stand united by the threat of paradox. A family of paradoxes akin to the set-theoretic antinomies seem to allow one to derive a contradiction from apparently plausible principles. (...) Some of them concern the interaction between propositions and worlds, and they appear to afford the means to map classes of propositions into propositions – or, likewise, classes of worlds into worlds – in a one-to-one fashion that leads to contradiction. Yet another family of paradoxes threaten the view that whatever could exist does, in fact, exist, which is in line with modal realism, for example. This article aims to survey and identify the source of each family of paradoxes as well as to outline some responses to them. (shrink)

In recent years, many disciplines have become interested in the scientific study of morality. However, a conceptual framework for this work is still lacking. In The Moral Background, Gabriel Abend develops just such a framework and uses it to investigate the history of business ethics in the United States from the 1850s to the 1930s. According to Abend, morality consists of three levels: moral and immoral behavior, or the behavioral level; moral understandings and norms, or the normative level; and (...) the moral background, which includes what moral concepts exist in a society, what moral methods can be used, what reasons can be given, and what objects can be morally evaluated at all. This background underlies the behavioral and normative levels; it supports, facilitates, and enables them. Through this perspective, Abend historically examines the work of numerous business ethicists and organizations--such as Protestant ministers, business associations, and business schools--and identifies two types of moral background. "Standards of Practice" is characterized by its scientific worldview, moral relativism, and emphasis on individuals' actions and decisions. The "Christian Merchant" type is characterized by its Christian worldview, moral objectivism, and conception of a person's life as a unity. The Moral Background offers both an original account of the history of business ethics and a novel framework for understanding and investigating morality in general. (shrink)

This essay argues for a model of pictorial representation which aims to explain the relationship between pictorial content and pictorial accuracy. Focusing on cases where pictures are intended to convey accurate information, the model distinguishes between two fundamental representational relations: on one hand, a picture expresses a content; on the other, it aims at a target scene. Such a picture is accurate when the content it expresses fits the target scene it aims at. In addition, the model follows the traditional (...) division of content into two aspects: singular content specifies the particular individuals which a picture is of, and attributive content specifies the properties and relations which the picture ascribes to those individuals. For a picture to be accurate, both aspects must be matched in the target. I call this the Three-Part Model because it distinguishes between the triad of factors, singular content, attributive content, and target, which together determine pictorial accuracy. Though previous work on depiction has not recognized the distinctive role played by target, I will argue that it is essential in order to make sense of accuracy judgements across a range of central cases.

I present a puzzle for absolutely unrestricted quantification. One important advantage of absolutely unrestricted quantification is that it allows us to entertain perfectly general theories. Whereas most of our theories restrict attention to one or another parcel of reality, other theories are genuinely comprehensive taking absolutely all objects into their domain. The puzzle arises when we notice that absolutely unrestricted theories sometimes impose incompatible constraints on the size of the universe.

We criticize attempts to define hope in terms of other psychological states and argue that hope is a primitive mental state whose nature can be illuminated by specifying key aspects of its functional profile.

This essay calls attention to a set of linguistic interactions between counterfactual conditionals, on one hand, and possibility modals like could have and might have, on the other. These data present a challenge to the popular variably strict semantics for counterfactual conditionals. Instead, they support a version of the strict conditional semantics in which counterfactuals and possibility modals share a unified quantificational domain. I’ll argue that pragmatic explanations of this evidence are not available to the variable analysis. And putative counterexamples (...) to the unified strict analysis, on careful inspection, in fact support it. Ultimately, the semantics of conditionals and modals must be linked together more closely than has sometimes been recognized, and a unified strict semantics for conditionals and modals is the only way to fully achieve this.

In this article, we sketch how theoretical neuroethics can clarify the concept of autonomy. We hope that this can both serve as a model for the conceptual clarification of other components of PIAAAS and contribute to the development of the empirical measures that Gilbert and colleagues [1] propose.

Sociologists often ask why particular groups of people have the moral views that they do. I argue that sociology’s empirical research on morality relies, implicitly or explicitly, on unsophisticated and even obsolete ethical theories, and thus is based on inadequate conceptions of the ontology, epistemology, and semantics of morality. In this article I address the two main problems in the sociology of morality: (1) the problem of moral truth, and (2) the problem of value freedom. I identify two ideal–typical approaches. (...) While the Weberian paradigm rejects the concept of moral truth, the Durkheimian paradigm accepts it. By contrast, I argue that sociology should be metaphysically agnostic, yet in practice it should proceed as though there were no moral truths. The Weberians claim that the sociology of morality can and should be value free; the Durkheimians claim that it cannot and it should not. My argument is that, while it is true that factual statements presuppose value judgments, it does not follow that sociologists are moral philosophers in disguise. Finally, I contend that in order for sociology to improve its understanding of morality, better conceptual, epistemological, and methodological foundations are needed. (shrink)

ABSTRACT This essay has three goals. The first is to introduce the notion of fundamentality and to argue that physicalism can usefully be conceived of as a thesis about fundamentality. The second is to argue for the advantages of fundamentality physicalism over modal formulations and that fundamentality physicalism is what many who endorse modal formulations of physicalism had in mind all along. Third, I describe what I take to be the main obstacle for a fundamentality-oriented formulation of physicalism: ‘the problem (...) of abstracta’, which asks how physical can accommodate phenomena such as mathematics and universals, and which modal formulations do not face. I canvas three solutions: the inapt for ground solution, the concrete restriction, and the contingency restriction. (shrink)

This biography of Emil du Bois-Reymond, the most important forgotten intellectual of the nineteenth century, received an Honorable Mention for History of Science, Medicine, and Technology at the 2013 PROSE Awards, was shortlisted for the 2014 John Pickstone Prize (Britain's most prestigious award for the best scholarly book in the history of science), and was named by the American Association for the Advancement of Science as one of the Best Books of 2014. -/- In his own time (1818–1896) du Bois-Reymond (...) grew famous for his groundbreaking research in neuroscience and his provocative addresses on politics and culture. His discovery of the electrical transmission of nerve signals, his innovations in laboratory instrumentation, and his reductionist methodology all helped lay the foundations of modern neuroscience. -/- In addition to describing the pioneering experiments that earned du Bois-Reymond a seat in the Prussian Academy of Sciences and a professorship at the University of Berlin, this book also recounts du Bois-Reymond’s family origins, private life, public service, and lasting influence. In talks that touched on science, philosophy, history, and literature, du Bois-Reymond introduced Darwin to German students (triggering two days of debate in the Prussian parliament), asked on the eve of the Franco-Prussian War whether France had forfeited its right to exist, and proclaimed the mystery of consciousness, heralding the age of doubt. The first modern biography in any language, "Emil du Bois-Reymond" recovers an important chapter in the history of science, the history of ideas, and the history of Germany. (shrink)

Tagging is the phenomenon in which regions of a picture, map, or diagram are annotated with words or other symbols, to provide descriptive information about a depicted object. The interpretive principles that govern tagged images are not well understood, due in part to the difficulty of integrating pictorial and linguistic semantic rules. Rather than directly combining these rules, I propose to use the framework of perspectival feature maps as an intermediary representation of content, in which the outputs of pictorial and (...) linguistic interpretation may be assimilated. The result is a simple and compositional semantics for tagged images. (shrink)

Because humans cannot know one another’s minds directly, every form of communication is a solution to the same basic problem: how can privately held information be made publicly accessible through manipulations of the physical environment? Language is by far the best studied response to this challenge. But there are a diversity of non-linguistic strategies for representation with external signs as well, from facial expressions and fog horns to chronological graphs and architectural renderings. The general thesis of this dissertation is that (...) there is an impressively wide spectrum of conventional systems of representation, corresponding to the many ways that the problem of communication can be solved, and that these systems can be described and explained using the tools of contemporary mathematical semantics. As a partial corrective to the countervailing norm, this work concentrates on the class of systems arguably most different from language— those governing the interpretation of pictorial images. Such representations dominate practical communication: witness the proliferation of maps, road signs, newspaper photographs, scientific illustrations, television shows, engineering drawings, and even the fleeting imagery of manual gesture. I argue that systems of depiction and languages embody a parallel technologies of communication. Both are based on semantics: systematic and conventional mappings from signs to representational content. But I also provide evidence that these semantics are profoundly divergent. Whereas the semantics of languages are based on arbitrary associations of signs and denotations, the semantics of systems of depiction are based on rules of geometrical transformation. Drawing on recent research in computer graphics and computational vision, I go on to develop a precise theory of pictorial semantics. This in turn facilitates a detailed comparison of iconic, image-based representation, and symbolic, language-based representation. A consequence of these conclusions is that the traditional, language-centric conception of semantics must be overhauled to allow for a more general semantic theory, one which countenances the wide variety of interpretive mechanisms actually at work in human communication.

The Kohlberg Gilligan Controversy has received intermittent but inconclusive attention for many years, perhaps reflecting the difficulty of bridging the two positions. This article explores the published evidence for Gilligan's claims of gender difference, gender identity difference, and role of caring in people's ethics. It seems that the evidence for pronounced gender differences in ethical attitudes within business is weak, even if gender identity is used instead of physical gender. The main propositions of Care Theory and recent advances in its (...) thinking are discussed. Special focus emerges on the notion of Attachment which seems to be the Care Theory ingredient both most able to survive critical scrutiny and most promising for bridging the divide between the Kohlberg and Gilligan paradigms. The Social Bonding Model and other possible bridge building conceptual structures are introduced. Finally, Max Weber's division between ethics of conviction and ethics of responsibility provides an overarching perspective both of the gap still to be bridged and the need to keep trying to bridge it.

Agents can think using concepts they do not fully understand. This paper investigates the question “Under what conditions does a thinker fully understand, or have mastery of, a concept?” I lay out a gauntlet of problems and desiderata with which any theory of concept mastery must cope. I use these considerations to argue against three views of concept mastery, according to which mastery is a matter of holding certain beliefs, being disposed to make certain inferences, or having certain intuitions. None (...) of these attitudes is either necessary or sufficient for mastery. I propose and respond to objections to my own recognition view of the conditions under which a thinker has mastery of a concept. (shrink)

Multinational enterprises (MNEs) have long had a reputation of not doing enough for their host communities in developing countries. This study critically examines the role of MNEs in community development initiatives in developing countries, using the Nigeria oil industry and the South African mining industry as case study.

The findings suggest that expectations for community development projects are greater in developing countries. (...) This study introduced new information on MNEs'local development programs that were drawn from interviews with MNEs'managers, government officials, and local communities. (shrink)

We define a formula φ in a first-order language L , to be an equation in a category of L -structures K if for any H in K , and set p = {φ;i ϵI, a i ϵ H} there is a finite set I 0 ⊂ I such that for any f : H → F in K , ▪. We say that an elementary first-order theory T which has the amalgamation property over substructures is equational if every quantifier-free (...) formula is equivalent in T to a boolean combination of equations in Mod, the category of models of T with embeddings for morphisms. Thus, we develop a theory of independence with respect to equations in general categories of structures, which is similar to the one introduced in stability but which, in our context, has an algebraic character.

Apologizing for Socrates places some of the Platonic and Xenophontic writings in the context of contemporary controversies over Socrates, providing a perspective in which many of the philosophic and literary features of the text can be explained. In addition, it sheds light on the apologetic techniques used by Plato and Xenophon.

Atomism is the thesis that every object is composed of atoms. This principle is generally regimented by means of an atomicity axiom according to which every object has atomic parts. But there appears to be a sense that something is amiss with atomistic mereology. We look at three concerns, which, while importantly different, involve infinite descending chains of proper parts and have led some to question standard formalizations of atomism and composition in mereology.

According to Frank Jackson’s famous knowledge argument, Mary, a brilliant neuroscientist raised in a black and white room and bestowed with complete physical knowledge, cannot know certain truths about phenomenal experience. This claim about knowledge, in turn, implies that physicalism is false. I argue that the knowledge argument founders on a dilemma. Either (i) Mary cannot know the relevant experiential truths because of trivial obstacles that have no bearing on the truth of physicalism or (ii) once the obstacles have been (...) removed, Mary can know the relevant truths. If we give Mary the epistemological capabilities necessary to draw metaphysical conclusions about physicalism, she will, while trapped in the black and white room, be able to know every truth about phenomenal experience.

In continuation with the New Thought movement that arose in the United States in the 19th Century, there is now a massive self-help industry that markets books and seminars. This industry has also extended to healthcare in the form of positive thinking, i.e., the idea that happy thoughts are essential for health. While some of these claims may seem reasonable and commonsensical, they are not free of problems. This article posits that positive thinking has some ethical underpinnings. Extreme positive thinking (...) may promote alternative forms of medicine that ultimately substitute effective treatment, and this is unethical. The emphasis on positive thinking for cancer patients may be too burdensome for them. Likewise, unrestricted positive thinking is not necessarily good for mental health. After considering the ethics of positive thinking, this article proposes a more realistic approach. (shrink)

The primary objective of this book is to open space for rethinking the relationship between art and politics. It seeks to combat one of the fundamental assumptions that has plagued many of the previous debates on this issue: that art and politics are distinct entities definable in terms of common properties, and that they have privileged points of intersection, which can be determined once and for all in terms of an established formula. This common sense assumption is rooted in a (...) transcendent illusion according to which there are more or less fixed characteristics that unify our terms, concepts, and practices in such a way as to guarantee their meaning. Against this substantialist approach, Radical History & the Politics of Art argues for a praxeological account that begins the other way around by analyzing specific cultural practices without presupposing a conceptual unity behind them. Such an orientation is radically historicist in the sense that it recognizes that all of our practices—be they linguistic, theoretical, aesthetic or political—are historically constituted and that they are necessarily part of a temporal dynamic. Hence the contingent nature of the labels used to classify various practices or even identify ‘practice’ as such. Radical history thereby proposes a significant departure from the extant debates on art and politics by maintaining that there is no ‘art’ or ‘politics’ in general, nor a singular relation between them. There are only historically constituted practices in various conjunctures, some of which have been labeled, through practical acts of denomination, as ‘artistic’ or ‘political.’ Instead of proposing one more response to the oft-repeated question ‘what is the relationship between Art and Politics?’ this book seeks to overcome the presuppositions that plague such a question. It thereby changes the very nature of the investigation by asking: ‘how do the diverse aspects of practices identified as ‘aesthetic’ and ‘political’ overlap, intertwine and sometimes merge in precise socio-historical force fields of action?

Thomas Hofweber has written a very rich book. In line with the conviction that ontology should be informed by linguistic considerations, he develops a systematic approach to central ontological questions as they arise in different regions of discourse. More generally, the book seeks to cast light upon the nature of ontology and its proper place in enquiry. His preferred methodology is not without consequence: it promises, for example, to solve what otherwise look like intractable philosophical puzzles raised by arithmetical practice (...) and numerical discourse, and, likewise, his treatment of propositional discourse has ramifications for larger questions to do with the prospects of metaphysical enquiry generally.

As it has historically been the case with many pandemics, the Covid-19 experience will induce many philosophers to reconsider the value of medical practice. This should be a good opportunity to critically scrutinize the way medical research and medical interventions are carried out. For much of its history, medicine has been very inefficient. But, even in its contemporary forms, a review of common protocols in medical research and medical interventions reveal many shortcomings, especially related to methodological flaws, and more importantly, (...) conflicts of interests due to profit incentives. In the face of these problems, we propose a program of “gentle medicine”. This term, originally formulated by philosopher Jacob Stegenga, describes a form of medicine in which physicians intervene less than they currently do. As part of this general program, we advance a series of reform recommendations that could be enacted both by medical staff in their everyday practice, but also by public health officials and policymakers.

Fichte's Foundations of Natural Right was one of the most influential books in nineteenth-century philosophy. It was read carefully by Schelling, Hegel, and Marx, and initiated a tradition in German philosophy that considers human subjectivity to be relational and intersubjective, thus requiring relations of recognition between subjects. The essays in this volume highlight this little-understood book's most important ideas and innovations. They offer discussions of Fichte's conception of freedom, self-consciousness, coercion, the summons, the body, and human rights, together with new (...) analyses of his deduction of right, his views on the social contract, and his arguments for the separation of right from morality. The essays expand and deepen ongoing debates in the scholarship and chart new avenues of thought about Fichte's most enduring work of political philosophy. They will be essential reading for students and scholars of German Idealism, nineteenth-century philosophy, and the history of political thought. (shrink)

A new trend in the philosophical literature on scientific explanation is that of starting from a case that has been somehow identified as an explanation and then proceed to bringing to light its characteristic features and to constructing an account for the type of explanation it exemplifies. A type of this approach to thinking about explanation – the piecemeal approach, as I will call it – is used, among others, by Lange (2013) and Pincock (2015) in the context of their (...) treatment of the problem of mathematical explanations of physical phenomena. This problem is of central importance in two different recent philosophical disputes: the dispute about the existence on non-causal scientific explanations and the dispute between realists and antirealists in the philosophy of mathematics. My aim in this paper is twofold. I will first argue that Lange (2013) and Pincock (2015) fail to make a significant contribution to these disputes. They fail to contribute to the dispute in the philosophy of mathematics because, in this context, their approach can be seen as question begging. They also fail to contribute to the dispute in the general philosophy of science because, as I will argue, there are important problems with the cases discussed by Lange and Pincock. I will then argue that the source of the problems with these two papers has to do with the fact that the piecemeal approach used to account for mathematical explanation is problematic. (shrink)

Resenha de "O contrato racial" de Charles W. Mills.

Can mathematics contribute to our understanding of physical phenomena? One way to try to answer this question is by getting involved in the recent philosophical dispute about the existence of mathematical explanations of physical phenomena. If there is such a thing, given the relation between explanation and understanding, we can say that there is an affirmative answer to our question. But what if we do not agree that mathematics can play an explanatory role in science? Can we still consider that (...) the above question can have an affirmative answer? My main aim here is to give an account that takes mathematics, in some of the cases discussed in the literature, as contributing to our understanding of physical phenomena despite not being explanatory.

A way to argue that something plays an explanatory role in science is by linking explanatory relevance with importance in the context of an explanation. The idea is deceptively simple: a part of an explanation is an explanatorily relevant part of that explanation if removing it affects the explanation either by destroying it or by diminishing its explanatory power, i.e. an important part is an explanatorily relevant part. This can be very useful in many ontological debates. My aim in this (...) paper is twofold. First of all, I will try to assess how this view on explanatory relevance can affect the recent ontological debate in the philosophy of mathematics—as I will argue, contrary to how it may appear at first glance, it does not help very much the mathematical realists. Second of all, I will show that there are big problems with it. (shrink)

I make three claims about the interactions between concept mastery and the knowledge argument. First, I argue that, contra Ball, the concept mastery response to the knowledge argument does not suffer from the heterogeneity of concept mastery. Second, I argue that, when doing metaphysics by relating propositions on the basis of whether a hypothetical agent who knew a base collection could infer a target proposition, it is legitimate to rely on propositions that are not contained in the base, as long (...) as those propositions are required for mastery of relevant concepts. One upshot is that, when checking whether the physical truths a priori entail the consciousness truths, it is fair game to rely on substantive truths about consciousness. Third, I argue that the only version of the knowledge argument that has any hope of succeeding against physicalism completely lacks the argument's driving intuition: that Mary learns something new when she emerges from the black and white room.

I examine two explanatory models of choking: the representationalist model and the anti-representationalist model. The representationalist model is based largely on Anderson's ACT model of procedural knowledge and is developed by Masters, Beilock and Carr. The antirepresentationalist model is based on dynamical models of cognition and embodied action and is developed by Dreyfus who employs an antirepresentational view of know-how. I identify the models' similarities and differences. I then suggest that Dreyfus is wrong to believe representational activity requires reflection and (...) attention. I also argue that the representationalist model of choking is preferable, since some embodied actions require appeals to representations, something not available to Dreyfus's anti-representational model.

Le 'Journal métaphysique', qui, primitivement, n'était pas destiné à la publication, est constitué par un ensemble de notes philosophiques rédigées au jour le jour. L'évidente différence de style entre les deux parties tient au fait que sous la pression de la guerre la pensée de l'auteur s'est tournée de plus en plus résolument vers le concret, vers l'existentiel, qui a trouvé dans le Journal métaphysique une des premières expressions qu'il ait revêtues en France. Il ne faut d'ailleurs pas parler de (...) l'existentialisme, mais une thématique de l'existence considérée dans sa spécificité tend à s'y constituer par une réflexion qui se concentre de plus en plus sur le corps propre (par opposition au corps-objet ou instrument), sur la sensation traitée non plus comme message mais comme façon d'être au monde, sur la mémoire, sur la volonté, etc. Des phénomènes métaphysiques tels que la télépathie, la lecture de pensées, etc. sont considérés avec une attention particulière et l'auteur va jusqu'à se demander s'il ne conviendrait pas d'inverser la relation communément pré-supposée entre le psychologique et le métapsychique et si la clef des phénomènes dits normaux ne devrait pas être cherchée dans le supra-normal.
