Wittgenstein afirma no Tractatus que a teoria das classes é supérflua na Matemática e que isso está relacionado ao fato de que a generalidade exigida pela Matemática não é “acidental” (TLP 6.031). O objetivo deste texto é elucidar essa afirmação chamando a atenção para o que, seguindo Gregory Landini, tomaremos como uma forma de Logicismo compartilhada por Frege e Russell. Esta forma de Logicismo tem dois princípios básicos, a saber: o uso de uma teoria lógica cujas variáveis estruturadas incorporam o (...) que hoje chamamos de teoria dos tipos simples e a análise de atribuições numéricas em termos de afirmações sobre conceitos ou atributos que empregam conceitos de ordem superior exatamente análogos aos chamados quantificadores ‘numericamente definidos’. Argumentamos que é esse arcabouço teórico que Wittgenstein está rejeitando em 6.031 e não apenas o uso da Teoria dos Conjuntos na Matemática. Também é defendido que a noção de classe ainda tem um papel essencial a desempenhar no Tractatus.AbstractWittgenstein claims in the Tractatus that the theory of classes is superfluous in Mathematics and that this is related to the fact that the generality required by Mathematics is not “accidental” (TLP 6.031). My aim in this paper is to elucidate this claim by calling attention to what, following Gregory Landini, I refer to as a form of Logicism shared by Frege and Russell. This form of Logicism has two main tenets, namely:the use of a logical theory whose structured variables embody what we nowadays call the simple theory of types and the analysis of number ascriptions in terms of assertions about concepts or attributes which employ higher-order concepts exactly analogous to so-called ‘numerically definite’ quantifiers. It is argued that it is this shared theoretical framework that Wittgenstein is rejecting in 6.031 and not just the use of Set Theory in Mathematics. It is also argued that the notion of class still has an essential role to play in the Tractatus. (shrink)

The present text discusses whether there is a tension between aphorisms 6.1-6.13 of the Tractatus and the Church-Turing theorem about the decidability of predicate logic. We attempt to establish the following points: (i) Aphorisms 6.1-6.13 are not consistent with the Church-Turing theorem. (ii) The logical symbolism of the Tractatus, built from the N-operator, can (and should) be interpreted as expressively complete with respect to first-order formulas. (iii) Wittgenstein’s reasons for believing that Logic is decidable were purely philosophical and the undecidability (...) result shows that there are aspects of his criticisms of Frege and Russell that become unjustified in light of these results.

Interpersonal relations play a critical role in both the conception and dynamics of Brazilian citizenship. Under the influence of neoliberalism, patients must build strategies to access high‐quality health care services. This study aimed to analyze the role of interpersonal relations involved in the access to and delivery of health care services in Brazil amid the influence of austerity policies and the role of nurses in enhancing citizenship through nursing care. Thirty‐one patients in a public hospital in Rio de Janeiro, Brazil, (...) participated in qualitative interviews. A lexical analysis was conducted to analyze the interview data using Alceste® software, version 2012. The results were interpreted in light of both theoretical constructs of the Brazilian citizenship and biological subcitizenship propositions. Two lexical classes revealed contents about strategies used by patients to access high‐quality health care. In the context of budget cuts due to austerity policies, cultural aspects of Brazilian citizenship have influenced access to high‐quality health care services by creating two distinct conditions. Some patients acted as super‐citizens, while others acted as subcitizens. Nurses across the globe must spearhead the struggle for universal and equitable health care access at all levels, without losing sight of wider sociocultural aspects. (shrink)

The evolution of a female penis is an extremely rare event and is only known to have occurred in a tribe of small cave insects, Sensitibillini (Psocodea: Trogiomorpha: Prionoglarididae). The female penis, which is protrudable and inserted into the male vagina‐like cavity during copulation to receive semen, is thought to have evolved independently twice in this tribe, in the Brazilian Neotrogla and the African Afrotrogla. These findings strongly suggest that there are some factors unique to Sensitibillini that have facilitated female (...) penis evolution. Here, several hypothetical factors are presented that may have enabled the evolution of the female penis in Sensitibillini. The female–female competition for nutritious semen, the oligotrophic environment, and the twin insemination slots with switching valve are considered to be the driving factors for female penis evolution. Additionally, the following factors are considered responsible for relaxing the constraint against female penis evolution: preexistence of the female‐above mating position, the elongated duct connecting the female pre‐penis with the sperm storage organ, and the small male genital cavity accepting the female genital tubercle bearing the opening of this duct. Understanding the factors enabling female penis evolution may also shed light on the evolution of the male penis. (shrink)

A pesquisa aponta as condições que motivaram as mudanças nos processos de disseminação da ciência, apresentando o ambiente das redes sociais digitais como espaços unificados de comunicação e de divulgação científicas. A partir deste contexto, busca evidenciar como esses espaços estão vulneráveis à desordem da informação. Para tanto, foram levantados os principais fatores relacionados à desordem no espaço digital, especialmente, nesses processos, e indicados alguns cuidados que precisam ser considerados para evitar ou minimizar esse problema. Trata-se de uma pesquisa bibliográfica (...) de natureza qualitativa, que buscou, a partir de uma revisão de literatura, de inferências e de interpretações, conectar a desordem da informação aos descuidados com as terminologias usadas na comunicação e na divulgação científicas. Considera-se que, para que a promoção da ciência mediada pelas redes sociais não seja permeada de desordens, é preciso que produtores e disseminadores de conteúdos científicos considerem que esse espaço possui peculiaridades que combinam um público heterogêneo e uma forma particular de comunicação e divulgação.

Following increasing public concern over the ethical and social implications of contemporary technology, computer science departments around the world have recently increased their efforts to incorporate ethics into their educational curriculum. For our redesigned undergraduate course on Computer Ethics at Rice University, in addition to teaching variety of fundamental ethical theories and approaches to technology, we also sought to emphasize the role of “social” technologies in mediating moral relations and to encourage students to consider moral decision-making, rather than as an (...) abstract rational process, as matter of affective care. To help us achieve this educational objective and inspired by the work of artist Jenny Odell, we designed an activity for students to practice focusing “deep” attention both on themselves and others. In this article, we describe in detail our rationale for this activity, report on lessons learned, and discuss potential applications for this activity in regard to the ongoing online teaching environment following the Covid-19 pandemic.

Diversos filósofos e matemáticos contemporâneos admitem que existe uma vertente da filosofia matemática denominada “Platonismo”, segundo a qual, em síntese, os entes matemáticos – números, pontos, retas, planos, _etc_. – são coisas que existem no mundo independentemente de nós. Na literatura especializada é recorrente a compreensão de que essa tese filosófica tem origem na teoria das formas de Platão. Entretanto, a assertiva de que os entes matemáticos existem em si mesmos não é encontrada na filosofia desse filósofo ateniense, observada a (...) passagem 509d, e seguintes, do seu diálogo _A_ _República._ Na verdade, segundo o pensamento matemático de Platão os entes matemáticos possuem um valor intermediário, como mostramos nas seções a seguir ao “reconstruirmos” o seu raciocínio da “linha dividida”, segundo os trechos da _República_: (1) _Livro V_: 477a-b, 477e, 478b, 478c, 478d; (2) _Livro VI_: 509d-e, 510a, 510b, 510c-d, 510e, 511a, 511 a-b, 511d, 511e; (3) _Livro VII_: 533 b-c, 534a.

O desenvolvimento tecnológico promoveu o aumento de produção e compartilhamento de conteúdo em plataformas digitais, sendo difícil gerenciar o acesso adequado a informações. O presente artigo tem como objetivo discutir os efeitos do direito ao esquecimento no ambiente digital, considerando o processo de desindexação como estratégia para operacionalizar a efetividade desse direito. Tomando como referências arcabouços teóricos-conceituais acerca da complexidade compósita da informação e de antinomias entre a dignidade da pessoa humana e a liberdade de expressão e o direito à (...) informação, oriundos, respectivamente, da Ciência da Informação e do Direito, analisam-se e discutem-se algumas decisões jurisprudenciais e posicionamentos doutrinários no cenário brasileiro. O direito ao esquecimento está cercado de ambivalências e desafios de ordens normativa, tecnológica e cultural, num compartilhamento de informações em níveis sem precedentes que interferem negativamente na sua efetivação no ambiente digital.

I suggest here ecologies of the nascent state, posing the following general questions: what is this state and what is it to live, to fabricate modes of life, in its immanence? I believe populating this state is, by right, ‘ecological’, even if what I offer here is only a sketch or glimpse, playful as it is, of the possibility of such modes of life, of dwelling. As I develop it here, the nascent is in flight of being. It is populated (...) by lesser, minoritarian existences. If it is ‘ecological’, it is because these existences, or modes of becoming, are themselves, in their own right, ‘ecologies’, that is, modes of dwelling, of life, on the ‘other side of existence’, as Antonin Artaud put it once, in exile from Being. The power to return eternally to the nascent state is the power to live, to dwell, in the absolute forgetfulness of Being, in the interstice where philosophy supposedly ends, but where it nevertheless begins again, in oblivion itself, where being is never already the verticality of Being, its difference with beings, but always nascent, in the beginning, eternally so.

Soren Kierkegaard's Works of Love, a series of deliberations on the commandment to love one's neighbor, has often been condemned by critics. Here, Ferreira seeks to rehabilitate Works of Love as one of Kierkegaard's most important works. He shows that Kierkegaard's deliberations on love are highly relevant to some important themes in contemporary ethics, including impartiality, duty, equality, mutuality, reciprocity, self-love, sympathy, and sacrifice. Ferreira also argues that Works of Love bears on issues peculiar to a religious ethic, (...) such as the role of God as "middle term," and the possibility of preserving the aesthetic dimensions of love in a religious ethic of relation.

The increasing use of digital technologies in judicial and arbitration proceedings increases the usage of digital evidence by the parties, which brings the necessity of creating patterns for adjudicators to admit and assess this new type of evidence. This paper generally addresses digital evidence focusing on the second moment in international arbitration proceedings. It also narrows the topic to hacked and leaked evidence and its admissibility in international arbitration. The literature review showed a significant amount of research devoted to the (...) evidence in arbitration. Some considered electronic evidence within one jurisdiction; others focused on certain forms of digital evidence such as electronic signatures. Papers on digital evidence in international arbitration approach arbitration rules for digital evidence but skip admissibility issues. No systemic and complex works research digital evidence in arbitration, explicitly focusing on the admissibility of hacked and leaked digital evidence from a comparative perspective. Also, no research deals with enforcing international arbitration awards relying on illegally obtained digital evidence. In these cases, there could be a possible violation of domestic public policy under the New York Convention terms (art. V, 2, b). That is why the paper aims to offer the concept of digital evidence in international arbitration, including hacked and leaked evidence, criteria of its admissibility and relevance, and design the arbitration guidelines for assessing hacked and leaked evidence. Comparative legal analysis of the international arbitration rules and national procedure law allowed us to compare the regulatory approaches to the definition of digital evidence and its admissibility worldwide. The method of legal modeling allowed designing model guidelines for arbitral tribunals to evaluate the admissibility and relevance of digital evidence, including hacked and leaked evidence. Moreover, the case study method allowed us to analyze jurisprudence and define criteria for admission of hacked and leaked evidence. We conclude that the admissibility of hacked and leaked evidence depends solely on the arbitrator’s broad discretion to assess the evidence. Nevertheless, thorough evidence analysis and a well-reasoned award are always mandatory. (shrink)

Hoje, chega ainda até mim a pergunta que Merleau-Ponty, em 1935, na École Normale Supérieure, fazia insistentemente a Desanti - 'Que é que tu te propões esclarecer com isso?' Como se a pergunta me fosse dirigida, tenho a impressão de responder que, nesta dissertação, pretendo tão só um pouco de luz sobre o mistério da morte. Tal como a percepção é um mistério, e cada um de nós vive no mundo no interior da fé perceptiva, assim o mistério da vida, (...) que nos permite a existência, envolve a si a esperança de que a morte seja aparência da dimensão do visível.

Aristotle says that a fallacy of accident takes place whenever something is held to belong in the same way to an object and to its accident (SE 5 166b28-30). The Received View among interpreters takes “accident” (συμβεβηκός) in that connection to stand for any predicate that is not identical to its subject, and makes the fallacy consist in mistaking predication for identity. Such an analysis, however, gives “accident” a meaning otherwise unattested in the corpus; makes all cases of the fallacy (...) inconclusive, whereas inferences of the same kind are warranted (with a qualification) at different places in the corpus; does not cover cases which in Aristotle’s view fall under the fallacy of accident, for which a different analysis and solution must be provided; and does not square with Aristotle’s own solution in terms of sameness or difference in substance and being. This chapter presents a new take on the subject, grounded on Aristotle’s expressed views in the Sophistical Refutations and other works, according to which the fallacy takes place whenever a substitution of co-extensives, or even of necessary equivalents, makes reciprocation fail to (necessarily) hold between relata.

According to John Searle, default positions, i.e., those intelligibility and action presuppositions, are some departing points from which pre-reflective and pragmatic assumptions are made. Postulating such points helps us deal with certain perennial philosophical issues, by leaving them aside. These problems are the existence of the external world, truth and facts, “direct” perception, the meaning of words, and causality. In this article, we argue that those default positions described by Searle constitute a default humanity, and their absence would dehumanize us. (...) This is particularly relevant in a default position: cooperation, which is the basis of collective intentionality and the milestone of human civilization. (shrink)

En Ciencia de la lógica, Hegel finaliza la lógica objetiva con un largo estudio de las categorías modales (realidad, necesidad y posibilidad). Nuestra propuesta es que tal estudio hay que entenderlo en confrontación directa con la situación dejada por Kant en los principios del entendimiento puro de KrV. Para defender tal tesis expondremos, en primer lugar, la exposición kantiana del problema; en segundo lugar, el desarrollo de la lógica de la esencia dentro de la obra; y, por último, la nueva (...) interpretación que propone Hegel de las categorías modales.

Our goal is to investigate the notion of self-agency in William James and Donald Winnicott. With James, we examine the descriptive element of what constitutes a self. With Winnicott, we explore his explanatory theory on self-emergence. Winnicott's perspective is presented here as the prehistory of the Jamesian self. James's conception of self is similar to the Winnicottian notion of an "integrated self", an embodied position that emerges from the organism's actions in the experiential field. The combination of the two approaches (...) leads to the idea that the self is a flux of identities emerging in interaction with others in the "transitional space" (an intermediate area of experience).

Social animals need to share space and resources, whether sexual partners, parents, or food. Sharing is indeed at the core of social life. Humans, however, of all social animals, have distinct ways of sharing. They evolved to become Homo Negotiatus; a species that is prone to bargain and to dispute the value of things until some agreement is reached.

En este trabajo examinamos el tópico de la responsabilidad en el derecho penal internacional a la luz de la filosofía de John Searle, y del fallo dictado por la Corte Penal Internacional en el caso de Thomas Lubanga. En el primer acápite analizamos la declaración de responsabilidad penal en función de la teoría de actos de habla de Austin y de Searle, tratándola como un acto ilocucionario cuyo significado es dependiente de un marco institucional específico. Luego, en el segundo acápite, (...) mostramos de qué forma tal marco puede reconstruirse como un ejemplo paradigmático de la realidad social construida descrita por Searle, especialmente en virtud del nexo entre mente, lenguaje y sociedad. A nuestro juicio, los conceptos de intencionalidad colectiva, atribución de funciones de estatus y poderes deónticos son fundamentales para entender tal nexo. En efecto, tal como argumentamos en la tercera sección, los sistemas de poderes deónticos asociados al derecho internacional no solo explican la aparición de Tribunales penales internacionales, como la Corte Penal Internacional, sino además el carácter imprescriptible de los crímenes de lesa humanidad. Los acuerdos internacionales que promueven y protegen los derechos humanos, y que tratan la imprescriptibilidad de aquellos crímenes, son objeto de análisis en la sección final, en donde exponemos algunas reflexiones finales a partir del caso Lubanga.

The formation of the education professional has been a top subject of studies during the history of education in Brazil and must be a human formation directly related to his or her emancipation as a social, individual person. This is his or her truth citizenship and sine qua non to the formation of a new man for the construction of a human culture. In this sense, the concept of man is the fundamental axis of formation of the education professional. Theoretical (...) matrices that have given rise to individualism and its powerful concepts are analyzed, as well as the new dominant ideas that, in an explicit or implicit way, construct in our society by different forms of social consciousness. There is a firm conviction that the understanding of man as alive, active, and conscious in material existence, according to concrete life, looks as the formation of consensus, organic emancipating scientific fundamental of radial change in social relations on a global society and with the possibility of human culture.

In view of Alexander of Aphrodisias’s and Porphyry’s respective positions on the issue, I discuss whether logos apophantikos is to be defined, as DI 4 seems to imply, by its being true or false or rather, as DI 5 seems to imply, by its representing the ontological combination/separation of substrate and attribute through the logical combination/separation of subject and predicate.

Is the dream of EU endangered? This book reviews classic and modern values and virtues, and uses them in order to rethink Europe's present politics and its future. The idea of the Republic was born with the political ethics of ancient Greece. The current international crisis obliges Europe to face the mirror of truth: What has become of the European Idea and how fares the European Constitution? It has been a long road from the Greek Politeia to the present lack (...) of values and financial monomania in Europe, who seems to have lost any harmony between the spirit, the soul and the body of her Constitution: the will and values of the people (material constitution), the text of the Lisbon Treaty (formal constitution) and its current political interpretation and action (real constitution), making Europe a two-tier or three-tier club, far from the dream of the founding fathers. Without republican values and virtues, and failing to uphold the European social model, the European Union would devolve into moral, social and democratic bankruptcy. (shrink)

_ Source: _Volume 48, Issue 1, pp 1 - 28 This paper is an attempt to think through Derrida’s newly discovered _Geschlecht III_, the third and missing installment of Derrida’s four part series on Heidegger and _Geschlecht_. I argue that Derrida’s reading of Heidegger in _Geschlecht III_ needs to be situated within the philosophico-political context of Derrida’s 1984–85 seminar—given under the general title _Philosophical Nationality and Nationalism_—from which _Geschlecht III_ is extracted. In the first part of the paper, I reconstruct (...) Derrida’s general problematic of national-humanism as he lays it out in the opening sessions of the seminar, before arriving at his reading of Heidegger, who will be part of “a sequence of German national-philosophism,” as Derrida calls it. In the second part, the paper turns explicitly to _Geschlecht III_ where, as I show, Derrida’s thoroughgoing denunciation of a national-humanism in Heidegger becomes all the more telling when seen through the theoretical matrix of the seminar.
