Resumo: Martin Heidegger desenvolveu uma análise da metafísica e da tecnologia que questionava radicalmente seus pressupostos ontológicos. Contudo, para Peter Sloterdijk, autor de uma revisão do motivo da clareira heideggeriana intitulada Domesticação do ser: clarificando a clareira, Heidegger padece daquilo mesmo que ele critica: uma pendência para a ontologia clássica que, desde pelo menos Platão e Aristóteles, separa o ser e o nada, basila o princípio de bivalência na lógica, excluindo qualquer terceira possibilidade, e permite os dualismos constitutivos da metafísica. (...) Seguindo o antropólogo Bruno Latour, o qual evidenciara que “modernidade” não é senão uma crença na cisão entre os polos de forma e matéria, sujeito e objeto, natureza e cultura, também Sloterdijk vai atribuir a Heidegger a pendência à ontologia clássica, elevada ao nível da cisão entre o ôntico e o ontológico. Diante disso, o que sugere Sloterdijk? Uma alternativa à ontologia clássica na cibernética de Wiener e Günther, reatando os laços, desfeitos por Heidegger, entre ontologia e antropologia. Este trabalho tem por intenção articular a crítica de Sloterdijk, a investigação de Latour e a revisão ontológicológica de Günther, a fim de assentar bases para compreensão do projeto sloterdijkiano de se pensar a antropologia a partir de pressupostos cibernéticos.: Martin Heidegger developed an analysis of metaphysics and technology that questioned its ontological presupositions. However, Peter Sloterdijk, author of a revision of the Heideggerian clearing, under the title of Domestication of being: clarifying the clearing, argues that Heidegger suffers from the same illness he criticizes: an abeyance relative to classical ontology, which, after Plato and Aristotle, separated Being and Nothingness, grounded the logical bivalence, excluding any third possibility, and allowing for the metaphysical dualisms. Following the anthropologist Bruno Latour, who has showed that “Modernity” is a belief in the split between the poles of form and matter, of subject and object, of nature and culture, Sloterdijk also assigns to Heidegger the dependence on classical ontology on the level of the split between ontological and ontic. In this respect, what does Sloterdijk suggest? An alternative to classical ontology in the cybernetics of Wiener and Günther, in order to reattach the links broken by Heidegger between ontology and anthropology. This work aims to articulate Sloterdijk’s critique, Latour’s enquiry and Günther’s ontological-logical revision, in order to open field for an understanding on the Sloterdijkian project of thinking anthropology from cybernetical hypotheses.

RESUMO Este artigo busca levantar algumas questões a respeito da proposta do filósofo alemão Peter Sloterdijk ao Antropoceno, termo em debate que define a época na qual o ser humano se configurou como um agente de transformação geológica e climática. O debate faz-se pertinente por conta da proximidade de Sloterdijk com nomes como Bruno Latour e Yuk Hui, autores que, de forma central ou tangencial, se debruçam sobre este problema. Neste artigo, começaremos trazendo alguns dos principais conceitos sloterdijkianos de (...) sua obra recente para, em seguida, analisar suas propostas de ‘paradigma homeotécnico’ e de ‘coimunismo’, levantando, ao fim, questões pertinentes às propostas mencionadas. ABSTRACT This paper aims to raise some questions concerning the German philosopher Peter Sloterdijk’s propositions regarding Anthropocene, a debatable term that serves to define the epoch in which human being made itself an agent of geological and climatic transformation. This debate is important because of Sloterdijk’s closeness with names such as Bruno Latour and Yuk Hui, authors that, in a more or less central manner, engage with such a problem. Here, firstly we will gather some of the main concepts of Sloterdijk’s recent work in order to analyze the ‘homeotechnological paradigm’ and the ‘co-immunism’ propositions, raising, at last, some relevant questions to the aforementioned propositions.

A proposta desse trabalho é apresentar alguns dos dilemas contemporâneos a serem enfrentados dentro do campo da filosofia política. Não mais se concentrando apenas em um conceito de bem e em uma busca por uma sociedade melhor ideal, a filosofia política deve sair de seus pressupostos eurocêntricos para confrontar o problema da alteridade e da multiplicidade existente no mundo multipolar. A geopolítica que se configura nos tempos atuais não comporta mais a ruptura imposta pelo pensamento bipolar ocidental, mas exige o (...) enfrentamento da diferença existente nos novos pressupostos que se impõem. É preciso, portanto, uma reconfiguração de mundo, que deve partir não somente da ação, mas de um pensamento formador capaz de comportar a mudança que nos é imposta. Para concretizar esse trabalho iremos utilizar o pensamento de autores que pensam o problema da alteridade e os novos conceitos de modernidade, como os professores Edward Said e Bruno Latour.

This article provides a state of the art review of the philosophical literature on scientific representation. It first argues that the topic emerges historically mainly out of what may be called the modelling tradition. It then introduces a number of helpful analytical distinctions, and goes on to divide contemporary approaches to scientific representation into two distinct kinds, substantive and deflationary. Analogies with related discussions of artistic representation in aesthetics, and of the nature of truth in metaphysics are pursued. It is (...) finally urged that the most promising approaches - and the ones most likely to feature prominently in future developments - are deflationary. In particular, a defence is provided of a genuinely inferential conception of representation. (shrink)

Kant’s critique/doctrine distinction tracks the difference between a canon for the understanding’s proper use and an organon for its dialectical misuse. The latter reflects the dogmatic use of reason to attain a doctrine of knowledge with no antecedent critique. In the 1790s, Fichte collapses Kant’s distinction and redefines dogmatism. He argues that deriving a canon is essentially dialectical and thus yields an organon: critical idealism is properly a doctrine of science or Wissenschaftslehre. Criticism is furthermore said to refute dogmatism, by (...) which Fichte means Spinozism. Schelling repudiates Fichte’s position in his Philosophical Letters by reviving Kant’s distinction. First, ‘critique’ for Schelling names a canon that is valid for all systems—including Spinozism—and thus favours none—not even the Wissenschaftslehre. Second, Schelling coins ‘dogmaticism’ to refer to what Kant calls ‘dogmatism’: reason’s uncritical claim to doctrine. Hence, he says all systems—even Fichte’s—are susceptible to the ‘enthusiasm’ of mistaking themselves for doctrines or ‘objects of knowledge’, instead of subjectively valid ‘objects of freedom’. I reconstruct Schelling’s argument for reviving Kant’s distinction, while noting two consequences for German idealism. First, if criticism favours no system, a system’s origin cannot be an act of knowledge, e.g., intellectual intuition, but only an act of endorsement. Second, if dogmaticism entails enthusiasm, a system’s goal cannot be absolute knowledge, but only infinite striving. Hence, by retrieving Schelling’s notion of dogmaticism, we can both gain a better understanding of the Letters and register the impact of a core Kantian distinction on the German idealist project.

The aim of the paper is to argue that all—or almost all—logical rules have exceptions. In particular, it is argued that this is a moral that we should draw from the semantic paradoxes. The idea that we should respond to the paradoxes by revising logic in some way is familiar. But previous proposals advocate the replacement of classical logic with some alternative logic. That is, some alternative system of rules, where it is taken for granted that these hold without exception. (...) The present proposal is quite different. According to this, there is no such alternative logic. Rather, classical logic retains the status of the ‘one true logic’, but this status must be reconceived so as to be compatible with (almost) all of its rules admitting of exceptions. This would seem to have significant repercussions for a range of widely held views about logic: e.g. that it is a priori, or that it is necessary. Indeed, if the arguments of the paper succeed, then such views must be given up. (shrink)

European thought begins with the Greeks. Scientific and philosophic thinking--the pursuit of truth and the grasping of unchanging principles of life--is a historical development, an achievement; and, as Bruno Snell writes in The Discovery of the Mind, nothing less than a revolution. The Greeks did not take mental resources already at their disposal and merely map out new subjects for discussion and investigation. In poetry, drama, and philosophy they in fact discovered the human mind. The stages in man's gradual (...) understanding of himself are revealed in the course of ancient literature from Homer to Virgil. A rational view of the nature of man slowly established itself in the creations of epic and lyric poetry, tragedy and literary criticism, pre-Socratic thought, and early Greek ethics all the way to the discovery of humanitas and the spiritual landscape of Virgil's Arcadia. The Discovery of the Mind is a landmark work in tracing this evolution of consciousness--one of the distinguishing characteristics of the history of man. (shrink)

Meillassoux seeks knowledge of transcendental reality, blaming Kant for the ‘correlationist’ proscription of independent access to either thought or being. For Meillassoux, correlationism blocks an account of the meaning of ‘ancestral statements’ regarding reality prior to humans. I examine three charges on which Meillassoux’s argument depends: (1) Kant distorts ancestral statements’ meaning; (2) Kant fallaciously infers causality’s necessity; (3) Kant’s transcendental idealism cannot grasp ‘the great outdoors’. I reject these charges: (1) imposes a Cartesian misreading, hence Meillassoux’s false assumption that, (...) for Kant, objects don’t exist without subjects; (2) misreads Kant, who infers causality’s necessity from the possibility of experience; (3) casts Kant’s idealism as subjective, ignoring his perspectival portrayal of it.

This paper defends an inferential conception of scientific representation. It approaches the notion of representation in a deflationary spirit, and minimally characterizes the concept as it appears in science by means of two necessary conditions: its essential directionality and its capacity to allow surrogate reasoning and inference. The conception is defended by showing that it successfully meets the objections that make its competitors, such as isomorphism and similarity, untenable. In addition the inferential conception captures the objectivity of the cognitive representations (...) used by science, it sheds light on their truth and completeness, and it explains the source of the analogy between scientific and artistic modes of representation.

Depersonalization is characterised by a profound disruption of self-awareness mainly characterised by feelings of disembodiment and subjective emotional numbing.It has been proposed that depersonalization is caused by a fronto-limbic suppressive mechanism – presumably mediated via attention – which manifests subjectively as emotional numbing, and disables the process by which perception and cognition normally become emotionally coloured, giving rise to a subjective feeling of ‘unreality’.Our functional neuroimaging and psychophysiological studies support the above model and indicate that, compared with normal and clinical (...) controls, DPD patients show increased prefrontal activation as well as reduced activation in insula/limbic-related areas to aversive, arousing emotional stimuli.Although a putative inhibitory mechanism on emotional processing might account for the emotional numbing and characteristic perceptual detachment, it is likely, as suggested by some studies, that parietal mechanisms underpin feelings of disembodiment and lack of agency feelings.

El modelo de ser humano: homo oeconomicus, impuesto por la racionalidad económica capitalista, ha tenido en las dos últimas décadas una metamorfosis compleja, a saber, la formación de un tipo de subjetividad representada en la figura del “emprendedor” o “su propio jefe” que, desde una nueva gramática teológica, encarna un proyecto mercantil solapado y subrepticio que condiciona las relaciones entre sujetos. En razón a esto, el propósito de este texto es pensar dicha problemática desde el ejercicio hermenéutico-crítico que lleva a (...) cabo el joven Marx, para someter al análisis las categorías de culpa, deuda, sacrificio y expiación destacadas por Walter Benjamin, a la luz de la categoría esencia subjetiva de la propiedad privada que permita entender cómo el capitalismo se vale hoy de la teología y su lenguaje para continuar responsabilizando al ser humano de su pobreza, de su riqueza o su fracaso económico.

This paper defends the deflationary character of two recent views regarding scientific representation, namely RIG Hughes’ DDI model and the inferential conception. It is first argued that these views’ deflationism is akin to the homonymous position in discussions regarding the nature of truth. There, we are invited to consider the platitudes that the predicate “true” obeys at the level of practice, disregarding any deeper, or more substantive, account of its nature. More generally, for any concept X, a deflationary approach is (...) then defined in opposition to a substantive approach, where a substantive approach to X is an analysis of X in terms of some property P, or relation R, accounting for and explaining the standard use of X. It then becomes possible to characterize a deflationary view of scientific representation in three distinct senses, namely: a “no-theory” view, a “minimalist” view, and a “use-based” view – in line with three standard deflationary responses in the philosophical literature on truth. It is then argued that both the DDI model and the inferential conception may be suitably understood in any of these three different senses. The application of these deflationary ‘hermeneutics’ moreover yields significant improvements on the DDI model, which bring it closer to the inferential conception. It is finally argued that what these approaches have in common – the key to any deflationary account of scientific representation – is the denial that scientific representation may be ultimately reduced to any substantive explanatory property of sources, or targets, or their relations.

IntroductionThe idea of video recording in the operating room with panoramic cameras and microphones is a new concept that is changing the approach to medical activities in the OR. However, VR in the OR has brought up many concerns regarding patient privacy and has highlighted legal and ethical issues that were never previously exposed.AimTo review the literature concerning these aspects and provide a better ethical and legal understanding of the new challenges concerning VR in the OR.ConclusionsThere is a disparity between (...) the two main legal models concerning VR in the OR, namely the European legal system ) and the American legal framework ). This difference mainly deals with two distinct bioethical paradigms: GDPR places a strong emphasis on protecting patients’ privacy to improve the public health system, whereas HIPAA indicates the need to generate protocols to safeguard the risks connected to medical activity and patient privacy. Following from this point, we may argue that, at the ethical and bioethical level, GDPR and HIPAA depend mainly on two different ethical models: a perspective based on moral acquaintances and weak proceduralism, respectively. It is worth noting the importance of developing additional guidelines concerning different world regions to avoid the ethical problems that may emerge when simply applying a foreign paradigm to a very different culture.

This paper argues for a broadly dispositionalist approach to the ontology of Bohmian mechanics . It first distinguishes the ‘minimal’ and the ‘causal’ versions of Bohm’s theory, and then briefly reviews some of the claims advanced on behalf of the ‘causal’ version by its proponents. A number of ontological or interpretive accounts of the wave function in BM are then addressed in detail, including configuration space, multi-field, nomological, and dispositional approaches. The main objection to each account is reviewed, namely the (...) ‘problem of perception’, the ‘problem of communication’, the ‘problem of temporal laws’, and the ‘problem of under-determination’. It is then shown that a version of dispositionalism overcomes the under-determination problem while providing neat solutions to the other three problems. A pragmatic argument is thus furnished for the use of dispositions in the interpretation of the theory more generally. The paper ends in a more speculative note by suggesting ways in which a dispositionalist interpretation of the wave function is in addition able to shed light upon some of the claims of the proponents of the causal version of BM.

A la fin du XVIIIe siècle, Emmanuel Kant pouvait encore voir dans les mathématiques le modèle même des jugements synthétiques a priori, c'est-à-dire dotés d'un contenu intuitif propre quoique non dérivé de l'expérience sensible. Des géométries non-euclidiennes à la théorie des transfinis de Cantor, les mathématiques du XIXe siècle vont cependant faire triompher des systèmes mathématiques résolument déductifs et non plus intuitifs. Sur fond d'interrogations quant à la légitimité de ces développements récents, interrogations renforcées par la découverte de paradoxes, d'âpres (...) débats vont alors opposer différentes écoles quant aux méthodes de preuve acceptables ainsi que quant à ce qui constitue le fondement même du savoir mathématique. Logicisme, formalisme et intuitionnisme ; ce sont, à l'époque, pas moins de trois conceptions des mathématiques (et trois programmes pour les mathématiques) qui s'affrontent, conceptions auxquelles il faut ajouter le psychologisme, qui se nourrit de l'essor des sciences humaines et de leurs prétentions épistémologiques. En collant au plus près des textes des principaux protagonistes, l'ouvrage présente de manière tout à la fois synthétique et précise les différentes positions en présence, en soulignant autant que possible leurs divergences, mais en montrant aussi les variations et inflexions qui ont marqué leur développement durant la période 1870-1930.

Este artigo problematiza o antropocentrismo na “esferologia” de Peter Sloterdijk, com sua narrativa da antropogênese como construção imunológica da “casa do ser”, na qual o humano, rompendo a “jaula” animal, constrói esferas, ilhas imunológicas de coexistência humana. O mito de Orfeu simboliza para Sloterdijk a imunologia: ao perder a amada, Orfeu reconstrói imunologicamente o complemento, neutralizando o espectro ausente como linguagem. Propomos um experimento filosófico, o “Anti-Orfeu”, no qual o perspectivismo cosmológico de Viveiros de Castro e Tânia Stolze Lima, pensado (...) de um ponto de vista topológico, serviria de contraponto para pôr em perspectiva a imunologia, apontando para a variação da diferença entre dentro e fora e para a “antropofagia”, como outra distribuição topológica que permite outra relação com a alteridade que não a imunologia. Com isso, apontamos para uma “esferologia do ponto de vista do inimigo”, da alteridade, permitindo modular a esferologia, evidenciando-a como diagnóstico da “autoimunidade” de esferas imunológicas.

The article turns to Deleuze and Guattari’s concept of state capitalism and their theorization of money and debt in their critique of capitalism to develop an analysis of the governmental management of the current crisis determined by ordo- and neoliberalism. The paper argues that analyses which fail to properly recognize the power of capital to determine both state apparatuses and economic policy thereby fail to grasp the real functioning of money, debt and the Euro in the crisis and end up (...) unwittingly supporting liberalism. This is true of positions such as heterodox theory that, though critical of conventional and neoliberal political economy, nevertheless continue to uphold the state as an independent or mediating mechanism in relation to the power of capital. The neglect of the role which money plays in the strategies of capital to control both the creation of value and the functioning of the state is to be found even in Foucault’s genealogy of neoliberalism, a neglect which undermines his analysis of power. The paper highlights the implications of the standpoint of state capitalism for a more incisive analysis of the current crisis that reveals what is at stake for political struggles. (shrink)

Social commerce as a subset of e-commerce has been emerged in part due to the popularity of social networking sites. Social commerce brings new challenges to marketing activities. And social commerce transactions like e-commerce transactions can be dangerous and cause harmful losses to personal finances, time, and information privacy. This article examines ethical issues and consumer assessments of the risks of using an e-service and how risk affects consumer evaluations and usage of Internet-based services and self-service technologies. Results from two (...) surveys totaling 1024 consumers indicated that as usage risk concerns increased, the perceived usefulness of an e-service and intention to use it decreased. Additionally as usage risk concerns increased the effect of subjective norm on PU and intention to use an e-service strengthened, and the effect of perceived ease of use on PU and intention to use an e-service weakened. These findings advance theory and contribute to the foundation for future research aimed at improving our understanding of how consumers evaluate new e-services, new commerce systems and settings, and self-service technologies in the social commerce era.

In the logic of theory change, the standard model is AGM, proposed by Alchourrón et al. (J Symb Log 50:510–530, 1985 ). This paper focuses on the extension of AGM that accounts for contractions of a theory by a set of sentences instead of only by a single sentence. Hansson (Theoria 55:114–132, 1989 ), Fuhrmann and Hansson (J Logic Lang Inf 3:39–74, 1994 ) generalized Partial Meet Contraction to the case of contractions by (possibly non-singleton) sets of sentences. In this (...) paper we present the possible worlds semantics for partial meet multiple contractions. (shrink)

This monograph section of Theoria is devoted to the notion of causation in modern physics. The four long essays and short epilogue contained in this volume constitute a representative sample of recent work by philosophers of physics on causality. All the contributions to this volume share a healthy respect for science, and what science may be able to tell us about causation: these essays look for a notion of causation that can make sense of modern physical science. And, as is (...) the norm in contemporary philosophy of physics, the discussions engage with science in its own terms, and not through the distorting lens of rational reconstruction. Although these are philosophical essays and are primarily aimed at a philosophical readership, they may also interest scientists. (shrink)

German classicist's monumental study of the origins of European thought in Greek literature and philosophy.

Mauricio Suárez and Agnes Bolinska apply the tools of communication theory to scientific modeling in order to characterize the informational content of a scientific model. They argue that when represented as a communication channel, a model source conveys information about its target, and that such representations are therefore appropriate whenever modeling is employed for informational gain. They then extract two consequences. First, the introduction of idealizations is akin in informational terms to the introduction of noise in a signal; for (...) in an idealization we introduce ‘extraneous’ elements into the model that have no correlate in the target. Second, abstraction in a model is informationally equivalent to equivocation in the signal; for in an abstraction we “neglect” in the model certain features that obtain in the target. They conclude that it becomes possible in principle to quantify idealization and abstraction in informative models, although precise absolute quantification will be difficult to achieve in practice.

I analyse critically what I regard as the most accomplished empiricist account of propensities, namely the long run propensity theory developed by Donald Gillies . Empiricist accounts are distinguished by their commitment to the ‘identity thesis’: the identification of propensities and objective probabilities. These theories are intended, in the tradition of Karl Popper’s influential proposal, to provide an interpretation of probability that renders probability statements directly testable by experiment. I argue that the commitment to the identity thesis leaves empiricist theories, (...) including Gillies’ version, vulnerable to a variant of what is known as Humphreys’ paradox. I suggest that the tension may be resolved only by abandoning the identity thesis, and by adopting instead an understanding of propensities as explanatory properties of chancy objects. (shrink)
