Nosso objetivo é responder a uma questão proposta por Richard Heck no artigo “Formal Arithmetic Before Grundgesetze”. Heck indaga a respeito das razões pelas quais Frege levou quase oito anos para honrar suas promessas de concluir seu grandioso projeto de fundamentar a matemática na lógica. Embora Heck tenha fornecido algumas respostas, pensamos que uma discussão filosófica mais adequada ainda pode ser oferecida. Este artigo tentará preencher essa lacuna apresentando o que entendemos ser o problema central enfrentado por Frege em _Die (...) Grundlagen der Arithmetik_: a falta de um critério unificado para fixar o significado das proposições de identidade da matemática. Acreditamos que o filósofo alemão finalmente tenha decidido preencher essa lacuna, fornecendo uma nova interpretação para o conceito de “extensão”, uma que acrescentasse alguns refinamentos importantes a sua concepção anterior. O novo conceito assim construído permitiu a Frege unificar seu tratamento das proposições de identidade, incluindo em seu sistema um critério universal para decidir a verdade de qualquer proposição de identidade apoiado por sua famosa lei básica V. Assim, nossa alegação será que a resistência de Frege e as dúvidas sobre a inclusão do axioma V como uma lei lógica em seu sistema foram a causa primária desse atraso. (shrink)

O objetivo desse artigo é lançar luz sobre a tese da indeterminação da referência de Quine, usando para isso a distinção feita por Frege entre agregados e conjuntos. Além da distinção fregiana, usaremos também algumas noções de teoria dos modelos, tais como “modelos alternativos” e “morfismos entre traduções”.

O objetivo principal deste artigo será tornar mais claro o papel desempenhado pela noção de “forma de vida” nos escritos de Ludwig Wittgenstein. Como pano de fundo desta discussão, teremos em mente a questão do emprego do termo “forma de vida” no plural ou apenas no singular. Investigaremos criticamente quatro possíveis interpretações oferecidas por diferentes comentaristas da obra de Wittgenstein. Cada uma delas se aterá a diferentes aspectos da noção de “forma de vida”.

The “observational categoricals” constitute a very special set of sentences of great importance in the last phase of Quine’s work. According to Quine, the grammatical structure and therefore the role played by these sentences considered by the philosopher as the neutral empirical content of theories would solve several difficulties in semantics and epistemology. Most urgent among them would be: the incommensurability of theories, their empirical verifiability, as well as explaining the language learning process. In consequence of the importance of their (...) task and their rather late appearance, we consider quite relevant to investigate in details the origin of these choice, as well as the structure and function of these sentences, very peculiars to Quine’s semantical approach.

O paradoxo da análise e a antinomia da relaçáo de nomeaçáo sáo dois argumentos que servem para explicitar um aspecto paradoxal das interpretações filosóficas da identidade. Meu objetivo nesse artigo será o de investigar esses paradoxos e seus papeis como limitadores de uma teoria semântica. Usarei como guia dessa investigaçáo a hipótese de que as dificuldades nas quais todas as teorias semânticas investigadas incorrem náo se devem a tese da relaçáo de nomeaçáo, como diria Carnap, mas ao caráter composicional dessas (...) teorias. Essa investigaçáo se dará em duas etapas. A primeira será uma investigaçáo a cerca das soluções que foram historicamente apresentadas para evitar esses paradoxos. Procuraremos mostrar que cada uma dessas soluções envolve de alguma maneira o problema de lidar com esse aspecto composicional. Em especial, daremos ênfase a uma tentativa fracassada de soluçáo defendida por Quine, Carnap e mesmo Wittgenstein e Russell, num certo período, que ficou conhecida como a tese da extensionalidade. A segunda etapa consistirá em uma avaliaçáo crítica sobre em que medida a verdadeira causadora dos paradoxos náo seria uma preferência filosófica equivocada por uma abordagem composicional da linguagem. Palavras-chave : Antinomia da relaçáo de nomeaçáo, Frege, Identidade, Paradoxo da análise, Tese da extensionalidade. (shrink)

Nesse artigo pretendo desenvolver um ponto bastante central de uma famosa discordância entre Quine e Davidson, uma disputa conheci-da na literatura como “a questão proximal x distal”. Em poucas palavras, enquanto Quine adota uma posição proximal, segundo a qual devemos localizar o conteúdo empírico das sentenças de observação já nas termina-ções neuronais dos falantes, Davidson prefere uma localização distal para esse conteúdo, pressupondo assim a existência de objetos no mundo. Essa discussão é de suma relevância para a compreensão do debate (...) em torno do “terceiro dogma do empirismo”, proposto por Davidson e recusado por Quine, bem como para a compreensão da posição semântica de Quine como um todo.

Este artigo trata do chamado “problema de incompatibilidade de cores”, enfrentado por Wittgenstein no Tractatus Logico-Philosophicus, em seus Manuscritos inéditos 105 e 106, e em seu único artigo publicado – “Some Remarks on Logical Forms” (SRLF). Nossa tarefa será dupla. Primeiro, pretendemos mostrar como e por que Wittgenstein ficou preso nesse dilema. Nossa segunda tarefa será muito mais específica.Tentaremos elucidar alguns detalhes sobre a impossibilidade de reduzir predicados de cor a unidades mais fundamentais de brilho, croma e intensidade. Nosso objetivo (...) é mostrar como e por que os números tiveram que ser introduzidos na estrutura interna das proposições elementares. Também queremos investigar como Wittgenstein tentou fazer isso através da ideia de um “esquema” e uma operação nãover-funcional. Pretendemos também apresentar algumas vantagens que Wittgenstein obteve ao usar uma notação de barra para sua construção dos “esquemas”.AbstractThis paper deals with the so-called “color incompatibility problem”, faced by Wittgenstein in the Tractatus Logico-Philosophicus, in his unpublished Manuscripts 105 and 106, and in his only published paper – “Some Remarks on Logical Forms” – (SRLF, for now on). Our task will be a twofold one. First, we aspire to show how and why Wittgenstein got stuck into that dilemma. Our second task will be much more specific. We will try to elucidate some details about the impossibility of reducing color predicates to more fundamental units of brightness, chroma, and intensity. We aim to show how and why numbers had to be introduced into the inner structure of elementary propositions. We also want to investigate how he tried to do that through the idea of a “scheme” and a non-truth functional operation. We aim also to present some advantages Wittgenstein gained from using a bar notation for his construal of the “schemes”. (shrink)

Resumo: o propósito desse artigo é circunscrever e discutir a autocrítica, feita por Wittgenstein no período de 1933-39, a uma das teses mais fundamentais do Tractatus (TLP): ”Há uma e apenas uma análise completa da proposição” (3.25). Chamaremos esse procedimento peculiar de a “Grande análise”. Os argumentos de Wittgenstein contra a sustentabilidade da sua antiga tese podem ser encontrados em algumas passagens do livro Investigações Filosóficas (IF), bem como em passagens do Grande Datiloscrito (BT). Conforme será argumentado nesse artigo, essa (...) autocrítica é uma consequência direta da preocupação de Wittgenstein, no período intermediário, com duas importantes propostas feitas por Frege nos §§18-24 do Os Fundamentos da Aritmética (FA) em relação o seu entendimento da noção de “atribuição numérica”. Nosso objetivo principal será mostrar de que maneira o movimento de autocrítica feito por Wittgenstein em relação a sua antiga concepção de “Grande Análise” teria sido influenciado por suas preocupações, no período intermediário de sua obra, com essas duas propostas feita por Frege no FA a respeito da noção de “atribuição numérica”. A fim de completar tal tarefa, será apresentada inicialmente de modo breve uma versão de como seria a “Grande análise” no TLP. Em seguida, selecionaremos e discutiremos algumas passagens do IF nas quais Wittgenstein recusa a completude e unicidade envolvida em sua prévia concepção tratariana de “análise”. Procuraremos destacar com clareza uma noção que estaria envolvida de um modo essencial na autocrítica de Wittgenstein: a noção de “ver como/ver aspectos”. Como será argumentado, essa noção, assim como a autocrítica feita por Wittgenstein, foram ambas diretamente influenciadas pela noção fregiana de “atribuição numérica”. Para completar essa segunda tarefa, teremos de revisitar e discutir algumas noções pertencentes ao período inicial da filosofia de Wittgenstein -- como a de “propriedades internas e externas” e a distinção entre “dizer e mostrar” -- ambas noções discutidas no TLP. No decorrer de nossa discussão, apresentaremos uma crítica feita por Wittgenstein a Russell, mas também a Frege, sobre a concepção de generalidade, ou mais especificamente, sobre o uso do quantificador existencial, proposta por ambos. Abstract: The purpose of this article is to discuss Wittgenstein 1933-39 self-criticism of one of the most fundamental tractarian theses: There is one and only one complete analysis of the proposition (3.25). Wittgenstein's arguments against his previous thesis can be found in some passages of the Philosophical Investigation (PI) as well as in the Big Typescript (BT). As we shall argue, Wittgenstein's self-critique is directly related to two important ideas proposed by Frege in §§18-24 of The Foundations Arithmetic (FA) with respect to his construal of “number attributions”. Our main goal in this paper will therefore be to show how Wittgenstein's self-criticism of his old conception of the tractarian “analysis” would have been influenced by his concerns in the middle period of his work with these two proposals made by Frege in FA regarding the notion of “numerical attribution”. Our first task will then be to connect Wittgenstein's self-criticisms to his former conception of “analysis” in the Tractatus Logico-Philosophicus (TLP). To accomplish this first goal, we will have to briefly present a version of how such analysis would look like in TLP. Our next task will be to pinpoint some passages of the PI in which Wittgenstein rejects the completeness and uniqueness involved in his previous construal of the analytical process. We will try to circumscribe clearly a crucial notion involved in Wittgenstein's self-critique: the idea of “seeing as/seeing aspects”. Our claim is that this notion, as well as Wittgenstein's self-criticism, were both directly influenced by Frege's construal of the “number attribution” presented in FA. To accomplish this second task, we will have to revisit and discuss some further concepts from an early period of Wittgenstein's philosophy, like “internal and internal properties” and the “saying/showing distinction” in TLP. On our way towards accomplishing this goal, we will present a curious complaint by Wittgenstein regarding Russell's, as well as Frege's conception of generality, or more specifically, on the usage of the existential quantifier suggested by both these authors.

In this paper, we make explicit the changing configurations of power relations that currently characterize the Brazilian Emergency Care System (SAMU) team in Belo Horizonte, Brazil. The SAMU is a recent innovation in Brazilian healthcare service delivery. A qualitative case study methodology was used to explore SAMU’s current organizational arrangements, specifically the power relations that have developed and that demonstrate internal team struggles over space and defense of particular occupational interests. The argument advanced in this paper is that these professionals (...) are developing their work in conditions of exposure, that is, they are always being observed by someone, and that such observational exposure provides the conditions whereby everyday emergency care practices are enacted such that practice is shaped by, as well as shapes, particular, yet recognizable power relationships. Data were collected through the observation of the SAMU’s work processes and through semi‐structured interviews. Research materials were analyzed using discourse analysis. In the emergency care process of work, visibility is actually embedded in the disciplinary context and can thus be analyzed as a technique applied to produce disciplined individuals through the simple mechanisms elaborated by Foucault such as hierarchical surveillance, normalizing judgment, and the examination.

This article tells the empirical story of women from seven villages of Kwale, the most southeastern county in the Coast Province of Kenya that borders with Tanzania—Lunga Lunga, Godo, Perani, Umoja, Maasailand, Mpakani and Jirani—as they searched for community health, equity, gender equality and peace on their own terms. This article shows that creative health initiatives can be successfully used as mechanisms for peace building. Since 2010, the Nikumbuke-Health by All Means projects from the University of Madison-Wisconsin in the United (...) States, have trained 57 health promoters and 32 female actors on disease prevention and health promotion that have outreached approximately 120,000 inhabitants around the county enhancing unity in diversity, and breaking down the walls of ethnic hostilities and prejudice. Because of its low cost and high effectivity, the United Nations awarded N-HbAM[1] the 2013 Public Service Award as a model of best practice in gender, community development and sustainable wellbeing. [1] In 2013, at the time of the UNPS Award the projects were still called Nikumbuke-Health by Motorbike. The name was changed in 2018 as the projects broadened in scope and geographical location.

The casting of maize seeds is a tool used by contemporary daykeepers in the Ayöök area of Oaxaca, Mexico, which along with the prognostications and prescriptions of the 260-day calendar, helps to cure illnesses and afflictions. This divinatory practice was also employed by precolonial tonalpouhque, who were experts of reading the tonalamatl, the pictographic manuscripts with calendrical, ritual and oracular content, such as the now called Borgia Group codices. In this article maize divination will be described and analyzed, arguing that (...) maize divination results in images that can be read in a similar way to these codices. The reading of maize is approached here by employing the concepts of signs and symbols as described by Carl Jung and the notions of chronotope and dialogical narratives by Mijail Bakhtin. The Jungian understanding of divinatory practices as a means of gaining consciousness of oneself is also applied to argue in favor of the therapeutic capacity of reading maize, as it offers relief and triggers action.

El consumo responsable se está convirtiendo en una de esas muletillas que tanto valen para un barrido como para un fregado.

El estudio de la segunda persona como condición del Yo en el discurso poético toma impulso en los estudios de teoría literaria a partir del surgimiento del ámbito relativamente reciente de la pragmática de la comunicación lírica. Esta perspectiva de estudio actual admite que el Yo lírico no se reduce a la categoría de mero «sujeto enunciativo» que explica en sí mismo el proceso locutivo de la enunciación; sino que es considerado la proyección del sujeto hacia la alteridad del interlocutor (...) (Yo) al interlocutario (Tú), es decir, la expresión del sujeto de la enunciación al destinatario postulado en el discurso. En ese sentido, la presencia textual del Yo y del Tú es interpretada como signo de una relación dialógica que se convierte en el sentido fundamental de la estructura poemática. En este contexto, se indagan los modos de postulación del Tú como signo de manifestación dialógica en la poesía de Juan Gelman. Para el objetivo de este trabajo, el marco teórico se compone de las posturas de Émile Benveniste (2004) sobre la enunciación; de Carmen Bobes Naves (1991) y de Jesús Maestro (1998) acerca de las manifestaciones de la expresión dialógica en el discurso lírico; y de Margarida Bassols y Anna M. Torrent (1997), de Amparo Tusón (2015) y de Álvarez Muro Alexandra (2001) sobre las condiciones formales de la conversación. (shrink)

An increase in the number of older people with dementia is currently a trend around the world. In low and middle countries, effective public health services are not yet well‐developed, and family care‐givers may be overwhelmed by the requirements of care. This paper has two purposes: to share findings from an ethnographic study about family dementia care practices in Brazil and to draw attention to the significance of the materiality of care practices in the family context. The study was conducted (...) in Belo Horizonte, Brazil. We describe the care trajectory of one family and, analysing data using the insights of Actor Network Theory, show the significance of objects in a networked relation of care. In particular, we show how incontinence products such as adult diapers assume different positions in the network, acting as either mediator or intermediary of care in relation to other elements of the network composed of family members and their living situation, the person with dementia herself, the doctor, and Brazilian health policies. Although the diaper is often seen as an ordinary object for care providers, its participation in a care network shapes relations, activating conflict, financial constraint, and disciplining the body of the person with dementia.

The building of itself is an act moved from the hopes and dreams of becoming. Dreams project a future that can be, and hope is the force required to achieve them. The life project is an exercise in awareness that begins with imagining what you want to be and be aware of the relationship with the world. Leisure is lived from internal motivations and is auto-condicionated to seek the opportunities realization of dreams. Education for Leisure must recover the ideals of (...) life, learning to live the leisure, and spark the imagination for the realization of dreams. This paper presents the research results on what you want to be and how to realize them in their free time; this is a descriptive case study investigation with the phenomenological method. (shrink)

Paul Feyerabend, entre os anos de 1948 e 1970, discutiu diversas questões concernentes à mecânica quântica: problema da medição, a complementaridade e o “corte” entre o regime macro e micro, foram alguns dos assuntos mais estudados. Desde seus primeiros trabalhos acadêmicos, é possível identificar aspectos que o serão caros durante toda sua vida, como é o caso da relação entre conhecimento físico e visões de mundo. A partir de uma reconstrução de seu pensamento (entre os anos de 1948 e 1970), (...) o presente artigo busca compreender como suas críticas à mecânica quântica o levaram a defender que a física clássica é mais fundamental que a mecânica quântica, não o contrário, além de discutir a relação entre conhecimento físico e visão de mundo, algo que, para Feyerabend, é indissociável.

Com base na produção bibliográfica de Niels Bohr, entre os anos de 1913 e 1931, o presente artigo busca reconstruir o processo de elaboração das duas principais ideias do físico dinamarquês: os princípios de correspondência e complementaridade. Através desta reconstrução, busca-se analisar as possíveis motivações (a nível físico, filosófico e em prol de uma agenda de pesquisa) que guiaram Bohr neste período de elaboração da correspondência e complementaridade. Ao analisar este processo, é possível identificar que ambos os princípios estão interligados, (...) de maneira que, para a compreensão mais ampla do pensamento bohriano, é preciso considerar ambos os conceitos enquanto agentes praticamente indissociáveis. Outro aspecto discutido é quais lições epistemológicas e ontológicas Bohr nos apresenta, ao propor a correspondência e complementaridade. (shrink)

Developments in professional practice can be related to ongoing changes in relations of power among professionals, which often lead to changes in the boundaries of practices. The differing contexts of practices also influence these changing relations among health professionals. Legislation governing professional practice also differs from country to country. In Brazil, over the past 12 years, in a climate of deep disagreement, a new law to regulate medical practice has been discussed. It was sanctioned, or made into law, but with (...) some notable changes, in July 2013. Of interest to us in this paper are the ways the proposed legislation, by setting out the boundaries and scope of medical practice, ‘interfered’ in the practices of other health professions, undermining many ‘independent’ practices that have developed over time. However, even taking into account the multiple routes through which practices are established and developed, the role of legislation that seems able to contradict and deny the historical realities of multiple, intersecting practices should be critically interrogated. In this paper, we use the theoretical resources of poststructuralist thinking to explore gaps, ambiguities, and power relations implicit in the discourses that constituted this law. We argue that although the new law can be understood as a social and political device that will interfere in the organization of other health professions’ practices, such legislation is only part of what constitutes change in a consolidated professional practice. And while it is important to understand the effects of such legislation, healthcare practices are also realized or ‘made real’ through ongoing relations of knowledge and power, including, as we will see in this case, activities of resistance. The problem, then, is to understand the practical arrangements, including legislation, traditions and routines, values and knowledge that come to shape the practices of nursing in a particular context.

An emerging literature has begun to document the emotional consequences of everyday executive functions on emotional distress. Little is known, however, about whether this relation is mediated by other variables. A multiple mediation model was proposed to integrate core concepts of daily executive dysfunctions with emotional distress in order to increase understanding of their relationship to psychological well-being and emotional regulation. The working hypothesis was that dimensions of well-being and emotional regulation may be a suitable mediator. It was hypothesized that (...) dimensions of well-being and emotional regulation are a possible mediator between the executive dysfunctions and psychological distress. Participants were 122 undergraduate students from university courses in General Education and Social Education at, the Universidad Complutense de Madrid, with a mean age of 21.76. Results indicate that several dimensions of psychological well-being and emotional reappraisal strategies mediate the relationships between daily executive dysfunctions and psychological distress. Implications of these data are discussed. (shrink)

Because a large number of molecular mechanisms involved in gene regulation have been described during the last decades, it is now becoming possible to address questions about the global structure of gene regulatory networks, at least in the case of some of the best-characterized organisms.This paper presents a global characterization of the transcriptional regulation in Escherichiacoli on the basis of the current data. The connectivity of the corresponding network was evaluated by analyzing the distribution of the number of genes regulated (...) by a given regulatory protein, and the distribution of the number of regulatory genes regulating a given regulated gene. The mean connectivity found (between 2 and 3) shows a rather loosely interconnected structure. Special emphasis is given to circular sequences of interactions (“circuits”) because of their critical dynamical properties. Only one-element circuits were found, in which negative autoregulation is the dominant architecture. These global properties are discussed in light of several pertinent theoretical approaches, as well as in terms of physiological and evolutionary considerations.

A partir da crítica nietzschiana do sujeito, o artigo pretende analisar os mecanismos de produção de si presentes nas sociedades midiáticas contemporâneas como uma manifestação do niilismo. Embora de­corrente da fluidez e fragmentação do sujeito, as formas atuais de construção de si permanecem ligadas à busca de identidade e surgem como uma forma contemporânea de crença no sujeito. Para o homem contemporâneo, não se trata de afirmar a liquidez do eu, mas de curar-se dela. Palavras-chave: Nietzsche; subjetividade; modernidade.

Resumen Nombrar implica ejercer el poder sobre lo nombrado, involucra coacción y coerción social. La atribución de nombres, adjetivos, designaciones, favorece la taxonomía cognitiva, pero también socio-ideológico-cultural. Cuando una Institución al servicio del Estado nomina, esas denominaciones tienen consecuencias en los sujetos nombrados. En México, a través de las prácticas semiótico- discursivas se llevó a cabo esta edificación del concepto de discapacidad con importantes implicaciones. El objetivo de este artículo es describir la construcción discursiva, a través de la historia de (...) la nominación de la discapacidad para vincular este hecho con el imaginario social de México y revisar las implicaciones socio-ideológicas resultantes. Para efectuar un primer acercamiento, estudiamos los términos con que se designa la discapacidad en los Censos de población y vivienda realizados por el organismo responsable y sustentamos la exposición del proceso a partir de las propuestas de Lyons y Serrano sobre las implicaciones semánticas vinculadas con la designación; de Thiebaut respecto a la articulación semántica del nombre con la pragmática del texto, y con apoyo en Koike para la co-construcción del significado.
