Anxiety shifts visual attention and perceptual mechanisms, preparing oneself to detect potentially threatening information more rapidly. Despite being demonstrated for threat‐related social stimuli, such as fearful expressions, it remains unexplored if these effects encompass other social cues of danger, such as aggressive gestures/actions. To this end, we recruited a total of 65 participants and asked them to identify, as quickly and accurately as possible, potentially aggressive actions depicted by an agent. By introducing and manipulating the occurrence of electric shocks, we (...) induced safe and threatening conditions. In addition, the association between electric shocks and aggression was also manipulated. Our result showed that participants have improved sensitivity, with no changes to criterion, when detecting aggressive gestures during threat compared to safe conditions. Furthermore, drift diffusion model analysis showed that under threat participants exhibited faster evidence accumulation toward the correct perceptual decision. Lastly, the relationship between threat source and aggression appeared to not impact any of the effects described above. Overall, our results indicate that the benefits gained from states of anxiety, such as increased sensitivity toward threat and greater evidence accumulation, are transposable to social stimuli capable of signaling danger other than facial expressions.

Uma boa entrevista precisa de uma entrada? Necessitamos aqui, realmente de uma apresentação de nosso entrevistado? Se sim, seremos sintéticos, porque estamos convencidos de que importa a fala de Renato Noguera. Deixaremos que a entrevista diga “algo” sobre ele que não possa ser pinçado rapidamente de seu currículo lattes, produção bibliográfica, palestras e bancas de trabalhos acadêmicos, não sem dizer, contudo, que Noguera é daqueles pensadores que aproximam o conhecimento das pessoas. Não escreve e nem fala como se estivesse em (...) uma Catedral, engomado e asséptico. Noguera é pop: dá entrevistas em programas de televisão com a mesma competência com a qual orienta seus estudantes, desenvolve pesquisas e escreve livros. Já há algum tempo, Renato Noguera é sinônimo de produção inovadora que contraria o epistemicídio negro e rasura as lacunas da filosofia. Nosso entrevistado engrossa as reflexões presentes nesta edição da revista Odeere/UESB, cujo tema central é “Afrofilosofias e saberes diaspóricos: Filosofias pretas nas palmas das mãos”, questionando silêncios de uma ciência branca-cis-euro-hetero-usa-normativa, pouco comprometida com a luta antirracista e a equanimidade. A ele agradecemos por nos conceder um pouco de seu tempo, tendo a internet nos servido de elo. A você dedicamos este trabalho, convidando-a a trilhar um percurso de leitura, o qual, se estivermos de acordo, apresentará: i) reflexão e avanço de conhecimento sobre uma filosofia negra; ii) outros caminhos para a filosofia, mais ao “sul”; iii) reinvenções de percurso de pesquisa, pois, ora, o entrevistado tem se voltado à filosofia para a infância. E por quê? Porque Erês, Ibejis, Exu Mirim, o menino Kiriku dão o que filosofar, tanto quanto Pinóquio, Mickey Mouse, Riquinho Rico ou o Pateta, não é mesmo? Esta entrevista não serve apenas aos estudiosos de filosofia, aos pesquisadores de categorias como raça, etnicidade e justiça cognitiva. Serve aquelxs interessadxs em ensinar e aprender filosofias negras, com vistas a denegrir a Vida numa articulação proativa e biocêntrica em favor da Comunidade. Em uma palavra: Ubuntu!

This paper aims to differentiate between lying and irony, typically addressed independently by philosophers and linguists, as well as to discuss the cases when deception co-occurs with, and capitalises on, irony or metaphor. It is argued that the focal distinction can be made with reference to Grice’s first maxim of Quality, whose floutings lead to overt untruthfulness, and whose violations result in covert untruthfulness. Both types of untruthfulness are divided into explicit and implicit subtypes depending on the level of meaning (...) on which they are manifest. Further, it is shown that deception may be based on irony or metaphor, which either promote deceptive implicatures or are deployed covertly. Finally, some argumentation is provided in favour of why these cases of deceiving can be conceptualised as lying. (shrink)

O texto discute a reiterada e repetida demanda pela qualidade e excelência exigida pela sociedade frente à educação contemporânea. Considerando alguns aspectos da modernidade/pós-modernidade em que vivem tanto os herdeiros de Prometeu, como os de Dionísio, caracterizados pelo hedonismo, e os de Hermes, que valorizam a comunicação, a criação e a mediação, postula-se que a educação vive sua crise de finalidade, não encontrando referências ou modelos para atualizar-se. Seu impulso legitimador foi diluído quando o cânone moderno de padrões objetivos de (...) conhecimento e organização em que se baseava o mundo, foram desacreditados frente a um cenário pós-moderno. Neste contexto, são discutidas as necessidades de escolhas, de suturar os opostos, de práticas de ruptura e de alternativas existenciais para impasses contemporâneos. (shrink)

ArgumentThe process of institutionalization of Political Science in Brazil was conditioned by the country’s position in the geopolitical scenario proper to the Cold War, strongly affected by the influence of the USA and, later on, by the military dictatorship experienced between 1964 and 1985. The first Brazilian professionalized political scientists were, during their youth, anti-Stalinist revolutionary militants. They had been financed by the Ford Foundation to pursue their PhDs in the USA. In this paper, I argue that the north-American model (...) of ideological war included governmental and non-governmental institutions. Among the latter, the FF played a crucial role because it had a lot of credibility in state bureaucracy and was able to captivate the potential copartners, who would benefit from its grant, even the anti-American ones. The FF was able to do so because it was keeping a distance from the bellicose image of the USA. In this way, because Brazilian youngsters were leftist, the FF was interested in financing their studies. And, because they belonged to the anti-Stalinist left, they were more open than the communists and wouldn’t oppose to exchange with the USA. (shrink)

Resumo: Este texto busca abordar o pensamento de Rosa Luxemburgo a partir da idéia fundamental que sustenta toda sua concepção de política: a noção de que a participação ativa das massas é a base de qualquer processo político e é essencial nos processos revolucionários. Esta idéia nos encaminha para a compreensão da política em Rosa Luxemburgo como aquisição de autonomia popular e é também o cerne de suas idéias acerca de um modelo de socialismo democrático, atravessando sua obra como um (...) todo e repercutindo, até os dias de hoje, na dinâmica política de muitos movimentos sociais e em partes da esquerda contemporâneos.Palavras-chave: socialismo - marxismo - autonomia popular - revolução.: This work aims to approach Rosa Luxemburg's thought from the fundamental idea that sustains her entire political conception: the notion that the active participation of the masses in the foundation of any political process is essential to the revolutionary process. This idea leads to an understanding of Rosa Luxemburg's political advocations such as the acquisition of popular autonomy. It is also the center of her ideas about a model of democratic socialism, pervading her entire work and exerting its effect on the current political dynamics of many movements and sectors of the contemporary left.

Na Crítica da razão pura (1787), Kant expõe uma teoria da analiticidade que pode ser resumida nos seguintes pontos principais: a contenção dos termos, a identidade entre eles e o princípio de contradição. Com base nestes critérios, Kant pensa que a aritmética não usa juízos analíticos. Em oposição, Frege defende, nos Fundamentos da aritmética (1884), que a teoria kantiana de analiticidade é equivocada e que juízos analíticos, incluindo os aritméticos, são lógicos. Pretende-se, portanto, com o uso da literatura secundária em (...) Hanna (2004), discutir as doutrinas de Kant e Frege acerca disso, sugerindo que a teoria de Kant não consegue se sustentar e que a teoria de Frege, embora problemática, possui um ponto promissor a partir da semântica de mundos possíveis de Plantinga (1974) e Kripke (2012).

Neste artigo abordaremos o tema da intuição e o método intuitivo no pensamento de Henri Bergson, tendo por objetivo mostrar a partir de quais problemas tal método pôde surgir e quais dificuldades ele tenta solucionar em seu desenvolvimento no decorrer de determinados textos do filósofo francês. Para alcançar o problema da intuição em Bergson, teremos que tratar brevemente de temas fundamentais de sua filosofia, a saber, a duração e o tempo; a intuição interior e seu contato com o Eu profundo; (...) o ser como mobilidade e a cisão de Bergson com a metafísica antiga, clássica, que vê o imóvel como essencial e a mudança como acidental. Discorreremos também acerca da metafísica bergsoniana e da ciência simbólica como formas de conhecimento do absoluto, seja ele intuitivo-espiritual ou analítico-material. Por fim, abordaremos o problema da expressão da intuição ou, em outras palavras, da comunicação da duração em termos espaciais; a dificuldade da linguagem e da inteligência de dizer o ser movente e a proposta bergsoniana de solução deste impasse através da introdução da metáfora, das imagens e dos conceitos flexíveis. Com o intuito de atender nossos objetivos principais e explicitar as dificuldades acima apontadas – mostrando de que forma Bergson as contorna –, além de esclarecer o funcionamento do método e do conhecimento intuitivo, iremos nos basear nos seguintes textos de Bergson: “A Introdução da Metafísica” (1903), a conferência intitulada “A Intuição Filosófica” (1911) e as duas introduções de “O Pensamento e o Movente” (1922), onde esses conceitos aparecem ou pela primeira vez, ou tomando desenvolvimentos decisivos.

Plato's Republic VII suggests that if we ask someone to philosophize when they are too young, they can become corrupted (537e–539d). Republic VII also suggests that to avoid this corruption, we must not expose youth to argument (539a–b). This is not a reasonable option outside of Kallipolis, so a question arises: does Plato describe how to correct corruption if we do not manage to prevent it? This paper shows that a parallel between this passage from Republic VII and a passage (...) from Laws X suggests that he does. Laws X describes an impious man who is corrupted in the same way as the youth exposed to philosophy prematurely in Republic VII. While we leave the youth to his corruption in Republic, the impious man is helped to overcome his corruption in Laws with a refutation followed by a myth (also called a charm). This paper analyses these steps in terms of Plato's psychology, showing that both corruption and correction require a destabilization of the soul, which in these passages is brought about through refutation. This destabilization allows for a reconfiguration, which, with something that can restabilize the soul (for example with myth), can be a reconfiguration for the better. (shrink)

Suele argumentarse que la contribución original de la Reforma a la teoría de la resistencia se basa en una exégesis del pasaje paulino de Romanos, según la cual sólo se debe obediencia a las autoridades que obran en favor del interés general. De ahí se derivaría una teoría constitucionalista de la resistencia protestante, que tendría en Calvino a uno de sus principales inspiradores. Sin embargo, en el derecho de resistencia calviniano la ciudadanía no es concebida como sujeto político en sentido (...) estricto: el pueblo no es ni el fundamento de la autoridad ni puede reemplazarla o resistir si incumple sus deberes religiosos, sociales o políticos. La resistencia activa no está justificada más que como excepción y su motor es únicamente otra autoridad legitimada divinamente, esto es, que ocupe un oficio público, es decir, un tutor. La existencia de una tutoría semejante implica reconocer la incapacidad jurídica del menor tutelado, esto es, el pueblo. Difícilmente puede hablarse aquí de constitucionalismo o democracia. El análisis de las ideas del reformador en el contexto en el que fueron puestas en práctica apoyará esta tesis. (shrink)

This paper shows the relevance of an evolutionary model for the study of language change. We focus on a cognitive and usage-based approach to language change, namely the Theory of Utterance Selection developed by Croft (2000). Croft's evolutionary approach takes its inspiration from neo-Darwinian evolutionary theory, particularly the Generalized Theory of Selection developed by Hull (1988), a philosopher of science. Language is viewed as a system of use governed by convention, and language change results from breaking with convention and propagating (...) this innovation through the linguistic community until it becomes a new convention. Crucially, altered replication can be equated with language innovation, and propagation of individual changes is the linguistic counterpart of the differential perpetuation or selection of replicators. We will argue within the framework of Cognitive Linguistics (Geeraerts & Cuyckens, 2007) for a more systematic integration of cognitive and social factors in the explanation of language change. The mechanisms for language innovation are cognitive, as the pnnciples of cognitive efficiency like prototypicality constitute the main motivations for language change and metaphor and metonymy the main cognitive mechanisms of semantic change. The mechanisms for propagation are essentially social, including processes such as accommodation, identity and prestige. All of these mechanisms occur in individual communicative acts and operate like an "invisible hand" (Keller, 1994). We illustrate the sociocognitive evolutionary model of language change with some case studies on semantic change in Portuguese. (shrink)

A violência doméstica contra a mulher é um dos mais graves problemas que a sociedade enfrenta. É uma forma de violência que não conhece fronteiras, nem obedece princípios ou leis.

Are proneness to forgive, optimism and gratitude associated with life satisfaction? The main aim of the current study was to examine whether and how life satisfaction is related to propensity to forgive one's transgressor. Additionally, it also explored the relationship between life satisfaction and other chosen psychological variables, such as optimism and gratitude. The study involved 338 persons between 16 and 83 years of age. For the measurement of psychological variables the following research tools were used: Satisfaction With Life Scale, (...) Transgression-Related Interpersonal Motivations Inventory, Gratitude Questionnaire, and Learned Optimism Test. Among the study participants satisfaction with life was positively correlated with the conviction about a permanent and ubiquitous nature of positive events, optimism and gratitude. The study also observed a negative correlation between satisfaction with life, the motivation for revenge and avoidance motivation, and the perception of a permanent and ubiquitous nature of adverse events.

¿Qué tenemos en común y qué nos separa de los animales? ¿Somos un animal más? Las humanidades clásicas, basadas en el excepcionalismo humano, han dado paso a las posthumanidades, que incluyen los estudios animales, así como otras perspectivas que desafían la noción tradicional del sujeto humano, como los estudios de género, poscoloniales y decoloniales, la ecocrítica o la teoría queer. Pensarnos en nuestra relación con los animales tiene consecuencias filosóficas en ámbitos como la ciencia, los afectos, el trabajo y el (...) desarrollo de políticas concretas de salud y de alimentación; todas ellas, zonas de contacto entre humanos y animales. Sobre estos encuentros, aunque nunca reparemos en ello, edificamos nuestro mundo.

Los argumentos, contradicciones, contextos e incluso tabúes que acoge este debate interdisciplinar ayudan a imaginar y a matizar unos presupuestos éticos posibles sobre los que replantear nuestra relación con los animales y, en último término, con nosotros mismos.

ArgumentThis article analyzes for the first time the earliest western maps of diseases in China spanning fifty years from the late 1870s to the end of the 1920s. The 24 featured disease maps present a visual history of the major transformations in modern medicine from medical geography to laboratory medicine wrought on Chinese soil. These medical transformations occurred within new political formations from the Qing dynasty (1644–1911) to colonialism in East Asia (Hong Kong, Taiwan, Manchuria, Korea) and hypercolonialism within China (...) (Tianjin, Shanghai, Amoy) as well as the new Republican Chinese nation state (1912–49). As a subgenre of persuasive graphics, physicians marshaled disease maps for various rhetorical functions within these different political contexts. Disease maps in China changed from being mostly analytical tools to functioning as tools of empire, national sovereignty, and public health propaganda legitimating new medical concepts, public health interventions, and political structures governing over human and non-human populations.

Health behaviours of preschool children have a considerable impact on the shaping of habits later on in their lives. Parents’ and guardians’ role is to develop positive health patterns and represent exemplary models to be followed by children. The aim of the paper is to present the use of correspondence analysis for the assessment of the relationship between eating habits of parents and children, as well as for the determination of the most common situations in which preschool children consume fast-food (...) products and to find the relationship between the frequency of fast-food consumption and BMI values in preschool children. The tests were carried out with the use of an own survey carried out in kindergartens in Białystok among parents dropping off and picking up children. 149 correctly filled questionnaires were obtained. The statistical analysis employs the chi-squared test and correspondence analysis. Among the tested children, a statistically significant relationship between body weight and sex was obtained. In the group of children and parents consuming fast-foods, a statistically significant relationship between the frequency of children’s and parents’ consumption of the products in question was noticed. A statistically significant relationship between the age of introduction of fast-food products into the child’s diet and their BMI was found. A situation that was statistically significant as far as contribution to frequent consumption of fast-food products by children, i.e. at least once a week, were children and parents shopping together. The relationship between the frequency of fast-food consumption by parents and children was presented in the form of correspondence maps, as well as the relationship between the child’s BMI and the age when the first fast-food product is served, and the relationship between the child’s BMI and the frequency of their consumption of fast-foods. Unfortunately, despite the high awareness among parents of the harmful effects of fast-food products and the widespread health education programmes, a number of the children in kindergartens were overweight or even obese. For this reason, the quality of the educational programmes in kindergartens, as well as in various media outlets, needs to be improved, with emphasis put on their effectiveness, in order to minimise the problem of the occurrence of overweight and obesity in children. It is also important for parents rearing children to pay special attention not only to their children’s menus, but also to foods consumed in the presence of children. (shrink)

The establishment of a functional vascular system requires multiple complex steps throughout embryogenesis, from endothelial cell (EC) specification to vascular patterning into venous and arterial hierarchies. Following the initial assembly of ECs into a network of cord‐like structures, vascular expansion and remodeling occur rapidly through morphogenetic events including vessel sprouting, fusion, and pruning. In addition, vascular morphogenesis encompasses the process of lumen formation, critical for the transformation of cords into perfusable vascular tubes. Studies in mouse, zebrafish, frog, and human endothelial (...) cells have begun to outline the cellular and molecular requirements underlying lumen formation. Although the lumen can be generated through diverse mechanisms, the coordinated participation of multiple conserved molecules including transcription factors, small GTPases, and adhesion and polarity proteins remains a fundamental principle, leading us closer to a more thorough understanding of this complex event.

For decision making in government, it is necessary to have well-structured sources of information. In several countries, it is difficult to access government data as the information are dispersed, disconnected, and poorly structured. For this reason, this work presents a framework to gather, unify, and enrich missing person data from distributed web sources. The framework allows inserting new tasks specific to the user’s domain to improve data quality. In this study, Brazilian missing person data from non-governmental organizations (NGOs) and governmental (...) websites were collected and semantically enriched. To enhance the understanding of the gathered missing people cases, we create interpretive models using machine learning techniques to extract knowledge and to encourage the use of standards for publishing the data that are frequently ignored by organizations, hindering analysis and decision-making on data. After the collection and semantic enrichment process, there was an increase of approximately 11% in the data present in the base. Also, the mining process evidenced the disappearance and reappearance of a person in Brazil according to several factors such as age, state initiatives, skin tone, hair colors, etc. (shrink)

Miroir, miroir de mes désirsAu seuil de la réversibilité, la libido ardente des imagesEn parcourant les perspectives de Lacan, Merleau-Ponty et Deleuze, je me propose de montrer comment l’image – une image dont le rôle, depuis Platon, a été réduit par la métaphysique occidentale à celui de simple copie – rend possible une pensée nouvelle non dualiste, une pensée ouverte par le désir, c’est-à-dire par ce qui dépasse tout dualisme simpliste et qui trouve dans l’image sa voie privilégiée.L’image du miroir (...) – considérée par le platonisme comme le simulacre par excellence, comme l’emblème de la copie déformante et trompeuse d’un modèle originaire harmonieux – donne à voir bien plus qu’elle ne nous montre : comme Lacan le remarquait dans son célèbre essai de 1949, devant le miroir, nous nous découvrons, comme les enfants, sujets du monde, mais aussi, inévitablement, sujets au monde. Le «je» – dont nous sommes in-formés par l’image du miroir – s’abîme, par cette même image, dans les l’inquiétante étrangété de l’autre, et par suite dans les gorges insondables de son désir. Si l’image du miroir nous permet d’embrasser la totalité de notre corps et d’apprécier en un regard notre statut de sujet, ce regard nous est toutefois restitué – aveugle et insistant – sous la forme d’un objet partiel qui nous interpelle comme sujets désubjectivés, comme sujets castrés, ou encore comme simples « taches » dans lapeinture du monde. L’image fixée par l’enfant dans le miroir fonde, paradoxalement, l’idée traditionnelle du sujet comme pôle dynamique de la relation je-monde. Comme le remarque Slavoj Žižek, en commentant Lacan, la capacité dynamique du sujet se fonde en somme sur une fixation excessive de l’image du sujet lui-même, fixation qui trouve son origine absente dans le regard entendu comme objet a, c’est-à-dire comme point aveugle de la conscience, lieu d’acquisition et de perte qui, par la castration du sujet, ouvre la plaie libidineuse et pulsionnelle de l’inconscient et renverse par là le désir de l’homme en désir de l’autre, comme le rappelle une célèbre formule de Lacan.Longtemps considérées comme porteuses d’illusions, comme l’illusion en tant que telle, les images nous montrent en fait la vérité de cette illusion : le monde est déformation et réversibilité, et nous-mêmes, prétendus sujets faisant face à son tableau inerte, n’en sommes que des taches. Au cours des mêmes années durant lesquelles Lacan élabore une théorie du regard, Merleau-Ponty, son interlocuteur direct – qui se réfère lui aussi au comportement de l’enfant devant le miroir – réfléchit sur la question du « en-être », c’est-à-dire de la réversibilité de la chair, ce tissu de différences qui nous constitue – les animaux et les choses – comme autant de plis d’un horizon commun. Pour Merleau-Ponty comme pour Lacan, dans une telle perspective, le sujet ne se défi nit pas positivement, mais comme écart par rapport à lui-même, comme coupure dans la peau de la conscience, comme plaie ouverte sur l’inconscient et sur le désir qui en jaillit abondamment. Ainsi, voir dans le miroir que, comme disait le poète, « je est un autre », implique que l’image soit libérée de son statut dévalorisant de « seconde chose » hérité du platonisme. Cela inaugure, en fait, une pensée sans dualisme. Gilles Deleuze travaillera lui aussi dans ce sens, lorsqu’il théorisera un renversement du platonisme à partir des images, dans son essai de 1966 Renverser le platonisme.Historiquement, le commencement de la philosophie a coïncidé avec la recherche d’une origine, d’une archè. Mais un monde où les relations nées du désir tracent des itinéraires imprévisibles, où le je et l’autre ne se distinguent plus, où sujet et objet ne connaissent plus de frontière, où la copie cesse de présupposer le modèle, un monde ainsi fait, a-t-il encore une origine accessible? Confronté à cette question essentielle, Merleau-Ponty théorisera – une fois encore à partir de la vision –, au lieu d’une origine en soi préétablie, un originaire en perpétuelle explosion. De son côté, Deleuze élaborera quelque chose d’analogue, à partir de la réflexion sur le cinéma qui l’occupera dans les années 1980 : il « encapsulera » les extases temporelles dans une image-miroir, une concrétion cristalline à plusieurs facettes où le monde se différencie sans cesse, dans un éternel retour.Mirror, Mirror of my DesiresOn the Threshold of Reversibility, the libidic Passion of ImagesIn a journey through the perspectives of Lacan, Merleau-Ponty and Deleuze, I shall show how images – the images that from Plato on have been relegated by Western metaphysics to the role of mere copies – allow us to trace the direction of a new and non-dualistic thought, a direction opened up by desire, that is to say, by something exceeding any simplistic dualism and fi nding precisely in images its privileged channel.The specular image – conceived by Platonism as the simulacrum par excellence, as the emblem of the deforming, deceiving copy of a harmonious preliminarymodel – makes us see more than it actually shows: as Lacan remarked in a renowned essay published in 1949, since childhood, in front of the mirror, we discover ourselves as subjects of the world, but also – and inevitably – as subjected to the world. The ego – of which we are in-formed by the specular image – is turned, through that very image, into the obscure, uncanny chasm of the other, and, consequently, in the unfathomable vortex of the other’s desire. Indeed, if in the mirror we can embrace the whole of our body and catch with a single gaze its status of subject, by the mirror that very gaze is however returned – blind and insistent – as a partial object summoning us as desubjectivized subjects, as castrated subjects, namely, as mere “stains” in the picture of the world. Quite paradoxically, the image fixed by the child in the mirror founds the traditional idea of the subject conceived as the dinamic pole of the relation between the ego and the world. In short, as Slavoj Žižek remarks commenting on Lacan, the dinamic capability of the subject is grounded on an excessive fixation of the image of the subject itself, fixation which finds its absent origin in the gaze meant as object a, namely, meant as that blind point of consciousness, that point of acquisition and loss which, by castrating the subject, opens the acies of the libidically throbbing wound of the unconscious and turns, to borrow a renowed Lacanian expression, man’s desire into the other’s desire.For long considered to herald illusions, images show us the truth of illusion itself: the world is deformation and reversibility and we – presumed subjects in front of its inert picture – are, on the contrary, its “stains.” In the same years in which Lacan was elaborating a theory of gaze, Merleau-Ponty, who was then a direct interlocutor of his, was articulating – by referring, as Lacan did, to the child’s behaviour in front of the mirror – a series of important reflections over the problem of the en-être, that is to say, over the problem of the reversibility of flesh, i. e., that differential fabric constituting us – animals and things – as variegated gatherings of a common horizon. For Merleau-Ponty, as well as for Lacan, according to such a perspective, the subject, far from being defined in a positive way, is defined by a gap in relation with its own self, that is to say, by a cut in the skin of consciousness, by a wound opening to the unconscious and to the desire spurting abundantly from the subconscious.To see in the mirror that, as the poet said, “I am an Other,” is to free images from the status of “second things” with which Platonism had dismissed them; it is, in other words, to inaugurate a non-dualistic thought. For his part, Deleuze will also engage in the same direction by theorizing a reversing of Platonism from the very standpoint of images in his 1966 essay Renverser le platonisme.The beginning of philosophy has historically matched with the search for an origin, namely, an arké. But in a world in which the relations inaugurated by desire trace unpredictable itineraries, in a world in which the ego and the other can no longer be distinguished, in a world in which the subject and the object know no more boundary lines, in a world in which model and copy cease to exist as the presupposition of one another, in such a world, I said, is it still possible to find an origin? By measuring himself with such a crucial question, Merleau-Ponty will theorize – once again from the standpoint of vision – an “originating in perennial explosion” instead of a narrow, pregiven origin. For his part, Deleuze will elaborate something similar in his reflection on cinema, which will keep him busy in the first half of the eighties, by capsulating the temporal dimensions in a mirror-image, i. e., a crystalline concretion in whose facets the world perennially becomes in an eternal differential return.
