This paper argues that the so-called ‘paradox’ of dehumanization is a mirage arising from misplaced abstraction. The alleged ‘paradox’ is taken as challenge that arises from a skeptical stance. After reviewing the history of that skeptical stance, it is reconstructed as an argument with two premises. With the help of an epistemologically structured but pluralistic frame it is then shown how the two premises of the Skeptic’s argument can both be debunked. As part of that it emerges that there are (...) a couple of ways how dehumanization can be realized, and one such realization can be sufficient for affirming the reality of dehumanization for a specific case.

This paper revisits Donnellan’s distinction between referential and attributive uses of definite descriptions and argues that it is not exhaustive. Donnellan characterizes the distinction in terms of two criteria: the speaker’s intentions and the type of content the speaker aims to express. I argue that contrary to the common view, these two criteria are independent and that the distinctive features may be coinstantiated in more than two ways. This leaves room for nonattributive and nonreferential uses of definite descriptions. Kripke’s notions (...) of general and specific intentions provide a framework that accommodates such cases. Additionally, it proves useful for the analysis of the use of proper names with specific nonsingular intentions. The paper also discusses how the interpretation of the use of definite descriptions as attributive or referential (or neither) is sensitive to which theory of singular thoughts one adopts. (shrink)

Este texto oferece uma reflexão nascida de uma experiência com literatura, poesia e também filosofia na escola, com turmas do ensino fundamental nos anos iniciais. A experiência foi iniciada em 2011 e deu origem a um projeto de pesquisa, ensino e extensão, hoje em curso em escolas públicas. O projeto tem como fundamentação teórico-metodológica pensamentos críticos à escola voltada para a formação compreendida como utilitarista. Concepção esta que segue dominante, a despeito das inúmeras mudanças na base curricular, ao longo do (...) tempo. Não parece razoável que a preocupação que promove as mudanças na organização curricular tome por base aspectos como o baixo rendimento na aprendizagem refletido em reprovações e “fracassos” ou no próprio abandono e evasão precoce da escola, sem que se questione as razões inerentes à experiência escolar. Diante desse fato, a reflexão aponta para a defesa de uma escola que possa ser compreendida como desinteressada na perspectiva de Gramsci e recorre à literatura e poesia como dispositivos para impulsionar o fazer pedagógico transformador. O estudo da literatura sobre poesia, assim como os resultados obtidos pela experiência em questão, permitem pensar uma concepção de escola revolucionária no sentido gramsciano e libertadora como propugnava Paulo Freire. Nesse sentido, propõe conexões com a felicidade, que conjuga o propósito da escola desinteressada com a filosofia de Epicuro. Na pesquisa, a poesia é compreendida como um caminho para se contemplar a valorização do lúdico, que é um aspecto dos mais relevantes para a aprendizagem nas infâncias. (shrink)

Qual é o objeto da lógica? Seria a arte de bem conduzir o discurso? Mas conduzí-lo para onde, com que finalidade? Haveria uma normatividade independente, que definisse o racional independente do real? É Lacan que pergunta e nos responde no sem. XIX: “eu proponho definir o objeto da lógica como aquilo que produz a necessidade de um discurso. E afirmo que o simbólico, o imaginário e o real se afirmam nos impasses da lógica. ” (LACAN, 2011, p. 40). Muitos comentadores (...) encaram os recursos lógicos de Lacan como uma provocação, mas entendo que não, pois são muito coerentes com seus princípios, tanto lógicos, quanto linguísticos, antropológicos e principalmente matemáticos.

This paper focuses on negative exemplarity-related emotions (NEREs) and on their educational implications. In this paper, we will first argue for the nonexpendability of negative emotions broadly conceived (section 2) by defending their instrumental and intrinsic role in a good and flourishing life. In section 3, we will make the claim more specific by focusing on the narrower domain of NEREs and argue for their moral and educational significance by evaluating whether they fit the arguments provided in the previous section. (...) In section 4, we will propose three educational strategies to foster NEREs’ positive moral role. In conclusion, we will point out that an exemplarist approach to character education would greatly benefit from a more fine-grained account of the emotions involved in the educational process and from a broader perspective on which of these emotions should be taken as valuable for educational purposes.

The notion of “individuality” in Plotinus is one of the most discussed. Throughout the Enneads, the problem of the individual subject arises from the complexity in understanding the relation between man and soul. To the intelligible man, also known as the inner or first man, a second man is added, so that “we have come to be the pair of them” 14.28-30). This question has been extensively addressed from different angles that lead either to a purely structuralist solution, or to (...) its criticism and the search for a more stable definition of subjective identity. The thesis that we will defend in this article, and that will indicate our position in the debate, tries to give a new perspective of the issue alluding to the sphere of life and its forms. The continuity between the different men will be determined by the continuity between their different forms of life, a primary issue to which the problem of individuality and the different modes of consciousness are subject.

The review examines the trilogy about time of VBV, which includes the poetic editions „Th:is.” (2000), “Will:” (2011) and “:was...” (2022), with the emphasis being the last volume, which appeared at the end of the past year. VBV's poetic texts are read through his ideas about “realliteratur” and the mediamarket “normalization” of modern culture, unfolded in a number of his theoretical observations. At the border between the poetic and the philosophical, at the point of coincidence and exchange between the two (...) projects of the VBV, a new toolkit appears for revising the status quo, both literary and political. The meta-poetic resource of VBV's “:was...”, as well as his trilogy as a whole, allows to see in a new and heuristic way the problems of performative societies at the height of the 21st century.

The Covid-19 pandemic has had a great impact on the life of every inhabitant of the planet. During 2020 and 2021 a significant amount of work on how the pandemic is being conceptualized and communicated has been done. Most work has focused on the role of metaphor in the construal of specific cognitive frames. In this paper, we turn to a similar but different conceptualization mechanism, i.e. simile. Drawing from recent socio-cognitive and discursive empirical approaches to similes, this paper focuses (...) on “target is like source” constructions in English and Spanish containing (corona)virus either as target or source of the simile. The analysis is based on 200 examples found in the digital media during the first wave of the pandemic in 2020. First, the constructions, conceptualizations and mappings are analyzed. Second, the relevant discourse features (genre type, relation to subjectivity, text location and structuring properties) are described. Finally, the cross-linguistic English-Spanish analysis shows that, despite the many coincidences in both datasets, there are different tendencies as for the use of culture-specific mappings and the genres where the similes occur in. The study aims at testing to what extent the general features characterizing similes also hold in the case of (corona)virus, both as source and as target. The corpus analysis contributes, in addition, to the emerging line of research on the use of figuration in the communication of the pandemic, as well as to the study of the discursive dimensions of similes in real settings.

Once upon a time, Aesop says, there was a donkey who wanted to be a pet dog. The pet dog was given many treats by the master and the household servants, and the donkey was envious of him. Hence, the donkey began emulating the pet dog. What happened next? The story ends up with the donkey beaten senseless, chased off to the stables, exhausted and barely alive. Who is to blame for the poor donkey’s unfortunate fate? Well, there could be (...) disagreement upon this, but we think emulation is to blame. And it’s on the kinds of envy-related emulation that we focus in this chapter. More analytically, we aim at vindicating the role of envy for moral exemplars within an exemplarist character educational framework. In the first section, we recall the central tenets of an exemplarist account of moral progress, and highlight how negative emotions, in general, have suffered a bad press within character education, with exemplarism being no exception. Then we provide a brief outline of standard strategies of defending envy by appealing to useful taxonomies of envy (e.g., Taylor 1988; Protasi 2016; Fussi 2018). After that, we put forward our 'Donkey Objection' by recalling Aesop’s fable on "foolish imitation", so as to show that when envy triggers mere emulation, it can bear devastating effects such as conformism and a lack of self-worth and personal integrity. In response to this objection, we bring into play a distinction between two rival forms of imitation—emulation and inspiration—and we coin the label of "inspired envy" for those forms of imitation by inspiration triggered by envy that lead to self-improvement avoiding morally detrimental consequences.

Ever since Putnam and Burge launched their respective attacks on individualist accounts of meaning the individualist has felt squeezed for space.1 Very little maneuvering room, it seems, is left for the philosopher who wants to deny that meaning and mental content depend on the speaker's social environment. One option, popular amongst individualists, is to grant that reference is socially determined but argue that there is nevertheless a notion of meaning or content that can be understood individualistically. That is, the individualist (...) can opt for a. (shrink)

Esta propuesta se inscribe en el marco de análisis y comprensión de los procesos de subjetivación contemporáneos como maneras de imponer una esencia a una existencia. Puesto que hemos sido edificadas con las imágenes de otros, las mujeres hemos debido construirnos cada una con ellas. Siendo muy diversos los desenlaces de esta construcción, somos sin embargo parecidas al compartir una particular manera de vínculo: la experiencia que denomino del deseo de ser. Estando siempre sin hacer, somos siempre siendo y, aunque (...) dadas ya por hechas, cada mujer es el resultado de un tremendo esfuerzo y paciencia cuya resolución permite vivir. (shrink)

In this work we present the complex relationship between sound and color in musical creation throughout history that continues to be fruitful in current musical composition. Synesthesia in music establishes a correspondence between sound and color and has been a constant debate since the 17th century. The complex nature of sound appears from ancient Greece in the school of Pythagoras in which the number becomes the configurator of harmony. Since then, different aesthetic attempts have arisen to relate color and sound (...) that reach today's electronic procedures in contemporary music. (shrink)

Embodied self-reflection goes beyond strictly rational thinking – we are thinking beings after all, for it includes our tacit concrete knowledge, as Michael Polanyi and David Bohm would describe the thinking that is implicit in our abilities to know how to do things such as knowing how to ride a bicycle. Polanyi describes this knowledge as: “[knowing] more than we can tell.” To become aware of the thinking below the surface of rational thinking is very challenging. Yet that is exactly (...) what is required for any kind of self-awareness and self-transformation to take place. To become aware of our own thinking essentially means becoming aware of oneself as a witness to our own thinking in the process of thinking. Bohm understands thinking as a movement and similarly to becoming aware of our physical movements through proprioception, so too can we become aware of our thinking as a movement. Proprioception of thinking implies proprioception of embodied thinking. -/- (Self-)reflection is (self-)examination or (self-)scrutiny is a process that requires the courage to question one’s self and with it the touchstones underlying our identity. This process is a form of parrhesia, for parrhesia is essentially also a form of infinite questioning, and which can also be applied to questioning the self. (shrink)

Asking students to generate a prediction before presenting the correct answer is a popular instructional strategy. This study tested whether a person’s degree of confidence in a prediction is related to their curiosity and surprise regarding the answer. For a series of questions about numerical facts, participants (N = 29) generated predictions and rated their confidence in the prediction before seeing the correct answer. The increase in pupil size before viewing the correct answer was used as a physiological marker of (...) curiosity, and the increase in pupil size after viewing the correct answer was used as a physiological marker of surprise. The results revealed that the pupillometric marker of curiosity was most pronounced if students were slightly more confident in their prediction than usual, and it was lower for predictions made with either very high or very low confidence. Furthermore, the results showed that high-confidence prediction errors and low-confidence correct responses yielded a pupillary surprise response, suggesting that highly unexpected results evoke surprise, independent of the correctness of the prediction. Together, results suggest that confidence in a prediction plays an important role in the occurrence of epistemic emotions such as curiosity and surprise. (shrink)

O texto analisa como o problema da coisa em si em Kant, enquanto fundamento real ou não do fenômeno, foi reelaborado pelos filósofos pós-kantianos e como estes buscaram solucionar o possível dualismo da filosofia crítica. A investigação se concentra sobretudo na resposta de Schopenhauer ao problema, evidenciado pela primeira vez pelo filósofo Friedrich Heinrich Jacobi, um dos grandes críticos da filosofia transcendental e do idealismo.

This article argues that citizens are responsible for the way they participate in political communication and debate, including for the quality of the pieces of information they post or disseminate on social media. This view contrasts with approaches that prioritise institutional responsibility in combating misleading information. Instead, in the article’s perspective, public and private institutional interventions are justified only when they aim at sustaining citizens in upholding their epistemic duties and contribute to an environment that facilitates responsible communicative exchanges.

O presente artigo tem por objetivo apresentar as contribuições da estética da existência em Foucault para o âmbito da educação. Inicialmente será apresentado, em linhas gerais, os três domínios de sua produção teórica: Arqueologia do Saber, Genealogia do Poder e Estética da Existência. Posteriormente, será exposto mais profundamente a terceira fase de sua obra, destacando as ideias acerca do conceito do Cuidado de Si e a sua relação com o ambiente escolar e a formação docente. A estética da existência caracteriza-se (...) como o terceiro domínio foucaultiano e concerne na ideia da vida como obra de arte, onde por meio das práticas de si, cuidado de si, governo de si, _parrhesía_ e exame de consciência o sujeito torna-se capaz de estilizar sua existência, moldando sua vida e sendo artesão de si mesmo. Os apostes teóricos que fundamentam a pesquisa, além do Michel Foucault, são: Veiga-Neto (2016), Brandão (2011), Barcelos, Rabelo e Rodrigues (2009), entre outros autores. Esses correlacionam a obra do Filósofo Michel Foucault com a Educação. A partir da relação estabelecida entre a Estética da Existência e a Educação, percebeu-se que a escola têm sido, desde a sua fundação até os dias de hoje, um espaço que prioriza a disciplina e a normatização. Portanto, faz-se necessário introduzir nesse espaço saberes que possibilitem um novo modo de formar os sujeitos para que esses sejam conscientes e desfrutem da sua liberdade, que por muitas vezes lhes é retirada.

Generalized Quantifier Theory defines superlative quantifiers at most n and at least n as truth-conditionally equivalent to comparative quantifiers fewer than n+1 and more than n \1. It has been demonstrated, however, that this standard theory cannot account for various linguistic differences between these two types of quantifiers. In this paper I discuss how the distinction between assertibility and truth-conditions can be applied to explain this phenomenon. I draw a parallel between the assertibility of disjunctions and superlative quantifiers, and argue (...) that those assertibility conditions are essentially modal. I use epistemic logic to formalize the assertibility conditions and revisit some of the linguistic puzzles related to superlative quantification. (shrink)

In this paper, I will account for the importance of the notion of exemplarity within the contemporary virtue-ethical debate, both in its classic formulation (e.g., Hursthouse 1999) and in the recent exemplarist moral theory advanced by Linda T. Zagzebski (2015; 2017). Despite their differences, which I will discuss extensively, both theories are centered on a characterization of an exemplary virtuous agent that serves as a standard for determining what, in a given situation, is right, wrong, dutiful and forbidden. The first (...) two sections will be devoted to an assessment of the strengths and weaknesses of these two approaches. In the third, I will propose a different role of radical (i.e., exceptional) individuals, i.e., saints and heroes, within a virtue-ethical theory of right action. (shrink)

«Lo otro» persistente. Lo femenino en la obra de María Zambrano es un estudio que recorre los textos en los que Zambrano expone su concepción de las mujeres y de lo femenino de modo explícito, y que también aborda las obras en las que la autora remite a los personajes femeninos de las letras españolas. Además, este trabajo dedica un importante lugar a las figuras de Antígona y Diotima sobre las que la filósofa reflexiona, y que constituyen un significativo (...) testimonio de su búsqueda de un nuevo tipo de razón (la razón poética) y de su expresión (los delirios). El enfoque de esta investigación muestra cómo los problemas centrales de la filosofía de María Zambrano están íntimamente vinculados con su indagación sobre lo femenino y deja constancia, al mismo tiempo, de la ambigüedad de las tesis que Zambrano formula sobre lo femenino.

RESUMO A partir da perspetiva de uma análise crítica do discurso, este artigo analisa a questão da autenticidade nos atos discursivos de expiação política. O objetivo é estudar de que forma a autenticidade dos atos discursivos de expiação política pode ser avaliada através de estratégias de reelaboração do passado empregadas em discursos de penitência. O artigo enfrenta a seguinte pergunta de pesquisa: de que forma estratégias de reelaboração do passado influenciam na autenticidade de um ato discursivo de expiação política? O (...) artigo analisa uma declaração de 2015 proferida por Shinzo Abe, antigo primeiro-ministro do Japão, e argumenta que, no seu ato discursivo de expiação política de 2015, ele desenvolveu uma estratégia de cancelamento da memória histórica nipónica. Tal estratégia impediu que a declaração de 2015 de Shinzo Abe fosse considerada um genuíno ato discursivo de expiação política. (shrink)

Las páginas de Kafka están repletas de figuras animales, cuya compleja simbología, que ha dado lugar a distintas interpretaciones, es capaz de hospedar también una lectura político-jurídica. Partiendo de un diálogo entre las historias con motivo animal de Franz Kafka y los seminarios de Jacques Derrida sobre la bestia y el soberano, el trabajo aspira: por un lado, a aclarar el sentido político-jurídico que, en la narrativa de Kafka, adquieren tanto el devenir animal como el devenir humano; y, por el (...) otro, a indagar el papel del cuervo y de su complejo simbolismo en determinados escritos del escritor checo. De ahí, dirige la mirada al apetito corvino que Kafka escenifica en El proceso para demostrar que la pasión del derecho moderno por la carne pertenece a la naturaleza más primitiva del mismo.

Publicada no ano de 1896, num contexto político adverso à propaganda anarquista – considerada como um crime pela Lei de 13 de Fevereiro desse mesmo ano –, esta obra revela os contornos doutrinários e históricos do anarquismo, sobretudo da feição dominante na militância anarquista em Portugal, o “anarquismo social”. Como assinala João Freire em “Revistas anarquistas portuguesas: entre a política e a cultura” (in Revistas, Ideias e Doutrinas, 2003), “o anarquismo social era certamente um social...

Ao longo da história, a relação entre a filosofia e a política tem-se revelado espinhosa, denunciando a dificuldade em se conceptualizar sobre o que é por natureza antagónico à cristalização, porque particular e pluralista. Na esfera da opinião, o filósofo deve restringir-se a analisar, criticar, rever e aperfeiçoar os valores políticos coevos, a explicar aos seus conterrâneos o universo de acepções sociais partilhadas, consciente de que a sua concepção fundamenta uma via entre as muitas poss...

In this article I analyze the connection between the concepts of “actuality”, “upcoming” and “origin” found in the early reflections of Walter Benjamin and Theodor W. Adorno to expose some of the defining borders of the transposition of criticisms made by both philosophers. Through the identification of “actuality” as a reflection on the conditions in which philosophy is legitimate, “upcoming” as a requisite for self-justification of philosophical knowledge, and “origin” as the claim of the historically unfinished, I show in what (...) sense a critical horizon is recovered by Benjamin and Adorno as an inexorable exercise of philosophical praxis.

Introduction: In 2020, according to the Global Cancer Observatory, nearly 10 million people died of cancer. Amongst all cancers, breast cancer had the highest number of new cases and lung cancer had the highest number of deaths. Even though the literatures suggest a possible connection between psychological factors and cancer risk, their association throughout studies remains inconclusive. The present systematic review studied the connection between psychological factors and the risk of breast and lung cancer, prior to a cancer diagnosis. The (...) psychological factors of trauma, grief, and depression were studied.Methods: The current systematic review was carried out across multiple databases in two phases, an initial exploratory research in June 2020, refined with a second electronic research in December 2020. The inclusion criteria included studies describing the association between trauma, posttraumatic stress disorder, grief, and depression with breast and lung cancer risk. The psychological data collection must have been carried out prior to a confirmed breast or lung cancer diagnosis, and accessed through self-report measures, questionnaires, clinical interviews, or clinical diagnoses. Study reports had to contain information about the incidence of cancer and effect size. The exclusion criteria were studies in which psychological factors were collected after cancer diagnosis.Results and Conclusion: A total of 26 studies were included. Although non-consensual, the findings from the present systematic review suggest that, in addition to the known risk factors, psychological factors may play an important role in the etiology of both breast and lung cancer. To include psychological factors as a variable that affects cancer development may be fundamental to opening new avenues for prevention and intervention.Systematic Review Registration: [www.ClinicalTrials.gov], identifier [CRD42020209161].

Mientras que Miguel de Unamuno vivió, su libro Del sentimiento trágico de la vida fue traducido a siete idiomas. Esta circunstancia provocó que los traductores se dirigieran a su autor para comentar la obra así como para hacerle partícipe de algunos problemas que les iban surgiendo.

Gracias al hallazgo de unas cartas inéditas, podemos reconstruir cómo fue el proceso de traducir Del sentimiento trágico de la vida, teniendo en cuenta todos los acontecimientos que se sucedieron al inicio del siglo XX.

Causal dispositionalism developed in metaphysics of science offers a useful tool to conceptualize shallow causes in behaviour genetics, in a way such that (a) it accounts for complex aetiology and heterogeneity of effects, and (b) genetic causal contribution can be considered to be explanatory. Genes are thus causal powers that make a difference.

One of Elizabeth Anscombe’s most decisive legacies is the rejection of modern legalistic morality, in the name of a rescue of Aristotelian-inspired natural normativity. However, as I will argue in this contribution, this legacy does not seem to have been fully collected, neither by those who, like Philippa Foot, are explicitly inspired by Anscombe’s work, nor by those who, while apparently opposing its assumptions, have also somehow recovered it by different routes, as emblematically does Christine Korsgaard in her constitutivist proposal. (...) In more detail, I aim to explore the relationship between teleology and normativity at the crossroads between neo-Aristotelian naturalism and constitutivism: both theories, though opposed, rest normativity on a link between function (the Aristotelian ergon) and practical reason and fail precisely in declining this relationship convincingly.

In this article we define a logical system called Hybrid Partial Type Theory ( $\mathcal {HPTT}$ ). The system is obtained by combining William Farmer’s partial type theory with a strong form of hybrid logic. William Farmer’s system is a version of Church’s theory of types which allows terms to be non-denoting; hybrid logic is a version of modal logic in which it is possible to name worlds and evaluate expressions with respect to particular worlds. We motivate this combination of (...) ideas in the introduction, and devote the rest of the article to defining, axiomatising, and proving a completeness result for $\mathcal {HPTT}$. (shrink)

Language is the main resource for meaningful action, including the very formation of selves and psychosocial identities, shaped by practical norms, beliefs, and values. Thus, language education constitutes one of the most powerful means for both social reproduction and social production and ideological maintenance and utopian innovation. In this paper, we attempt to emphasise the invaluable psychosocial, political, economic, and cultural function of language education in order to propose a critical view of the current transition from the monolingual to a (...) multilingual paradigm. We maintain that multilingual approaches tend to serve the neoliberal framework and reproduce its systemic inequalities. Therefore, we argue in favour of emancipatory multilingual practices that could embody a translingual pedagogy capable of promoting the development of capabilities, the recognition of otherness, and the cultivation of diversity. Rooted in critical theory, namely in Foucault’s notion of subjectification and Freire’s view of conscientisation, an emancipatory translingual pedagogy would enable and empower every learner to synthesise a contextually creative field of new semantic and pragmatic relationships. Critical language education would enhance the ethos of biophilia that fosters what we term the poetics of communality and selfhood, that is to say, the proactive commitment to expanding symbolic and existential novelty.

Model theory is the branch of mathematical logic looking at the relationship between mathematical structures and logic languages. These formal languages are free from the ambiguities of natural languages, and are becoming increasingly important in areas such as computing, philosophy and linguistics. This book provides a clear introduction to the subject for both mathematicians and the non-specialists now needing to learn some model theory.
