Como área interdisciplinar, as Ciências Cognitivas começam a se desenvolver em meados da década de 1950 a partir de uma concepção compartilhada sobre a mente, hoje chamada de cognitivista. Esses pesquisadores concebiam a mente com uma natureza representacional que opera por meio de computações simbólicas. Atualmente, há uma multiplicidade de abordagens e teorias sobre a mente. Nesse espectro de posições, há desde abordagens tradicionais, que concebem a mente como representacional, até abordagens bastante radicais, que negam qualquer natureza representacional para a (...) mente. Após introduzir este tema, apresentamos as críticas de William Ramsey à representação enquanto definidora das Ciências Cognitivas ou, em outros termos, à representação enquanto critério de demarcação do cognitivo. Desenvolveremos uma hipótese interpretativa para a crítica de Ramsey mobilizando o conceito de estratégia de pesquisa, de Hugh Lacey. Apresentaremos a distinção de Lacey entre adoção de uma estratégia e aceitação de uma teoria, discutindo a suposta independência avaliativa entre estratégia e teoria. Finalizaremos com a defesa de um pluralismo de estratégias nas Ciências Cognitivas. Diferente de concepções que buscam reduzir prematuramente as Ciências Cognitivas a uma única estratégia, o pluralismo que defendemos equilibra a eficiência na resolução de problemas com outros valores considerados importantes, como a abrangência empírica e a neutralidade no sentido de inclusividade e equitatividade de valores. No atual momento das ciências cognitivas, o pluralismo de estratégias constitui o caminho mais promissor. (shrink)

n the first part of the paper I will present Pritchard’s approach to Wittgenstein’s notion of hinge commitments, which is essential to his solution to the closure-based sceptical arguments. And, in the second par of the paper, I will raise some concerns that I have regarding Pritchard’s non-belief reading of the hinge commitments. In the third and final part, I make some concluding remarks regarding Pritchard’s overall strategy to solve the closure-based sceptical paradox.

Entende-se que os experimentos mentais são dispositivos da imaginação que podem nos fornecer crenças que constituem conhecimento. John D. Norton apresentou uma abordagem que se tornou influente para explicar como os experimentos mentais científicos podem produzir novos conhecimentos so- bre o mundo. Ele afirma que não há nada distintivo nos experimentos men- tais, uma vez que sustenta que eles funcionam exatamente como argumen- tos. Neste artigo, contestamos sua abordagem. Examinamos aspectos essen- ciais de sua abordagem, que envolvem as noções de (...) “argumento” e “inferên- cia” para mostrar que um sujeito que chega a saber algo através da execução ou condução de um experimento mental dificilmente será considerado como tendo efetivamente executado um argumento ou um processo de raciocínio inferencial.

: To address the question “on what there is” raised by Quine, and to accomplish the task of comprehending exhaustively the many ontological units that populate the great province of Being, we propose as an alternative to Puntel’s ontology a new ontology designated as “Structural Ontology” (SO). Such ontology is based on systematic-structural theoretical foundations, but leads to a diverse view in which structured factual units, structural configurations (dynamics), as well as apparent ontological units (objects), all encompassed by the temporal (...) sub-dimension that interconnects them, understood as an internal sub-dimension of the macro-dimension of Being, co-subsist. In this sense, we begin by situating the ontological theme in current philosophical discussion from a Quinean perspective. We then present a concept of truth derived from our reading of puntelian philosophy, which will be the point of connection between language and the world. Subsequently, we show how from the concept of truth, after a brief foray into philosophical semantics, we arrive at the ontological field from the ontological categories of structure and ontological state. Finally, we outline, in its general features, our structural ontology, which includes its own ontological notions that give new directions to philosophical understanding of this great theme.

In this paper we present a philosophical motivation for the logics of formal inconsistency, a family of paraconsistent logics whose distinctive feature is that of having resources for expressing the notion of consistency within the object language in such a way that consistency may be logically independent of non-contradiction. We defend the view according to which logics of formal inconsistency may be interpreted as theories of logical consequence of an epistemological character. We also argue that in order to philosophically justify (...) paraconsistency there is no need to endorse dialetheism, the thesis that there are true contradictions. Furthermore, we show that mbC, a logic of formal inconsistency based on classical logic, may be enhanced in order to express the basic ideas of an intuitive interpretation of contradictions as conflicting evidence.

Philosophical problems about the part-whole relation have been discussed throughout the history of philosophy, at least since Plato and Aristotle. In contemporary philosophy, the understanding of these issues has benefited from the formal tools of Classical Extensional Mereology. This paper aims is to defend mereological restrictivism against some constraints imposed by the vagueness argument. To achieve this, the paper is divided into three parts. In the first, I introduce the special composition question (hereafter SCQ) as formulated by [Van Inwagen, 1990] (...) and briefly present the three sets of theories that proffer answers to it. In the second part, I focus on the vagueness argument, that was presented by [Lewis, 1986, ] and [Sider, 2007, ] to defend mereological universalism. In the third section, I introduce the theory of natural properties by David Lewis. From this theory, I propose a new mereological operation labeled as natural fusion. The purpose of this operation is to falsify one of the premises of the vagueness argument. Then, I discuss some examples and counter-examples to natural fusion. (shrink)

This piece replies to a recently published article in the European Journal for Philosophy of Religion by J. L. Schellenberg and Paul Draper. They contend that the field of African philosophy of religion needs renewal, and they make several recommendations on how to achieve this. I agree with their recommendations, but I argue they have omitted a crucial problem and solution to renew the field; namely, a fundamental problem of the field is that it systemically excludes non-Western philosophies and scholars (...) and, therefore, the field needs to be decolonised.

I argue in this dissertation that natural properties play a central role in David Lewis' modal realism. To argue in favor of this thesis I present: a bottom-up explanation of a top-down possible world metaphysics; a new definition of natural properties and natural fusion, a new mereological operation. To achieve these aims, in the first chapter, I contextualize the discussion, in the second I resume the discussion about universals in contemporary philosophy and argue that, considering the distinct formulations of the (...) problem, class nominalism combined with modal realism might be the best solution. Furthermore, I discuss Devitt's solution in which he defends that the problem about universals is, in fact, a pseudo problem. In the third chapter, I introduce a minimal ontology of properties, regarding natural properties, I discuss the existing definitions, present a new one and discuss some theories of similarity, a notion that is in the core of the definition I propose. Besides, I present how natural properties benefit the definition of terms of nomological package, linked to its fundamentality role. I also present some applications related to the rationality role that encompass some well-known philosophical problems of the second half of 20th century. In the fourth chapter, I present some varieties of philosophical realism, I consider the theoretical advantages of taking scientific realism as background and I discuss one more utility of natural properties, the solution to the problem of eligibility of reference or, the Putnam's paradox. In the fifth chapter, I discuss how mereology is important to link several aspects of Lewis' modal realism. For such, I discuss the relation between composition as identity and ontological innocence of mereology and I present the natural fusion mereology, a new mereological operation that aims to minimize the problems of unrestricted composition.

Resumo Embora controversa, o contextualismo epistêmico alega oferecer a melhor explicação para alguns fenômenos analisados em epistemologia contemporânea, por exemplo: alega responder ou explicar o apelo de certos paradoxos e, ao mesmo tempo, manter a verdade de nossas alegações ordinárias de conhecimento. Conforme alegado por contextualistas, a vantagem de sua teoria ao explicar o apelo de certos paradoxos reside no fato de que nenhum princípio lógico precisa ser rejeitado. O paradoxo do prefácio – que consiste na aparente incoerência lógica que (...) ocorre quando o autor de um livro declara em seu prefácio que, apesar de acreditar que é altamente provável que tudo o que o livro afirma seja verdadeiro, também é altamente provável que o livro contenha, pelo menos, algum erro – parece não ter sido explorado o suficiente pelos contextualistas. Portanto, pretendemos sugerir uma versão do paradoxo do prefácio apresentando um argumento análogo ao argumento que os contextualistas costumam apresentar para explicar o paradoxo cético. Desta maneira, pretendemos oferecer, por meio de uma análise contextualista, uma explicação para o paradoxo do prefácio. Se a resposta contextualista é ou não adequada para esse paradoxo, isso será questão de disputa e não nos caberá discuti-la aqui. Meu objetivo é apenas sugerir que uma análise contextualista semelhante à aplicada ao paradoxo cético pode ser construída para explicar o paradoxo do prefácio. Palavras-chave: Contextualismo; Paradoxo do prefácio; Paradoxo cético. (shrink)

Each scientific study emerges in its own particular time and marks a new step in the development of human thought.1 Big History materialized to satisfy the human need for a unified vision of our existence. It came together in the waning decades of the twentieth century, in part, as a reaction to the specialization of scholarship and education that had taken hold around the world. While this specialization had great results, it created barriers that stood in contrast to a growing (...) unity among our global communities. These barriers were increasingly awkward to bridge, and, thus, Big History emerged as a successful new framework. (shrink)

Essa comunicação possui dois objetivos. Em primeiro lugar, pretendo esboçar as diferentes alternativas teóricas contemporâneas que procuram responder ao conhecido “ problema dos universais”. Para isso, apresentamos os nominalismos de predicados, classes, semelhanças e a teoria de tropos. Em segundo lugar, pretendo mostrar, inspirado no trabalho de David Lewis, como o nominalismo de classes, a noção de propriedade natural e uma teoria de mundos possíveis prometem resolver o problema em questão.

In the clear and exhaustive paper of Juan Balbi the development of the post rationalistic model of psychotherapy is well synthesized, starting from its origins in behaviour therapy and cognitivism.

In this paper, we present a formalism for handling polysemy in spatial expressions based on supervaluation semantics called standpoint semantics for polysemy (SSP). The goal of this formalism is, given a prepositional phrase, to define its possible spatial interpretations. For this, we propose to characterize spatial prepositions by means of a triplet ⟨ image schema, semantic feature, spatial axis⟩⁠. The core of SSP is predicate grounding theories, which are formulas of a first-order language that define a spatial preposition through the (...) semantic features of its trajector and landmark. Precisifications are also established, which are a set of formulae of a qualitative spatial reasoning formalism that aims to provide the spatial characterization of the trajector with respect to the landmark. In addition to the theoretical model, we also present results of a computational implementation of SSP for the preposition ‘in’. (shrink)

Developed through a series of conceptual analyses (Edmund Husserl, Vilém Flusser, Ludwig Wittgenstein and Walter Benjamin) and case studies (Fernando Lopes’s Belarmino and Jeff Wall’s Mimic), this article delves into the relationship between gesture, attunement and atmosphere and how it unfolds in photographic works dealing with urban space. The first section focuses on the role played by photography in the film Belarmino, which raises questions about both the representation of urban phenomena and issues related to expression and gesture in boxing. (...) The second section discusses Husserl’s thinking on image consciousness and his surprising reference to a “photograph” of a boxer, which reveals the relevance of his phenomenological approach when it comes to defining the aesthetic properties of gesture-images. The third section examines the principles of Flusser’s philosophy of gestures, focusing on the semantic field of attunement and its connection with various elements related to photography, gesture, moods and affects. The question of gesture in photography—both the gestures of the photographed and those of the photographer—can be articulated with the notions of attunement and atmosphere, which go beyond semiological, psychological and communicational approaches and are important for our understanding of aesthetic and artistic experiences. Finally, if photography is a privileged way of studying atmospheres and gestures (as suggested by the Benjaminian notion of optical unconscious) and their connection with the inner life of the subject, in relation to urban space this study often acquires an intersubjective, social and political dimension, as in Jeff Wall’s Mimic.

While Hegel’s political philosophy has been attacked on the left by republican democrats and on the right by feudalist reactionaries, his apologists see him as a liberal reformer, a moderate who theorized about the development of a free-market society within the bounds of a stabilizing constitutional state. This centrist view has gained ascendancy since the end of the Second World War, enshrining Hegel within the liberal tradition. In this book, Renato Cristi argues that, like the Prussian liberal reformers of (...) his time, Hegel was committed to expand the scope of a free economy and concurrently to ensure that the social practice of subjective freedom did not endanger political stability and order. Aware that a system of mutual advantage failed to integrate the members of civil society and that profound social disharmonies were ineradicable, Hegel adopted the views of the French liberal _doctrinaires_, who sought to realize the principles of the French Revolution by supporting Louis XVIII’s sovereign assertion of the monarchical principle. Not surprisingly, Hegel hailed the French _Charte_ of June 1814 as a beacon of freedom. Endorsement of the monarchical principle was meant to prevent the atomized individuals of civil society from gaining control of the state through appeals to popular sovereignty. This challenges most conventional interpretations of Hegel’s theory of the state and draws it closer to the conservative-authoritarian end of the political spectrum than is usual. (shrink)

We present a philosophical motivation for the logics of formal inconsistency, a family of paraconsistent logics whose distinctive feature is that of having resources for expressing the notion of consistency within the object language. We shall defend the view according to which logics of formal inconsistency are theories of logical consequence of normative and epistemic character. This approach not only allows us to make inferences in the presence of contradictions, but offers a philosophically acceptable account of paraconsistency.

Furthermore, we argue that an intuitive reading of the bivalued semantics for the logic mbC, a logic of formal inconsistency based on classical logic, fits in well with the basic ideas of an intuitive interpretation of contradictions. On this interpretation, the acceptance of a pair of propositions A and ¬A does not mean that A is simultaneously true and false, but rather that there is conflicting evidence about the truth value of A.

O objetivo geral da pesquisa da qual esse artigo faz parte é investigar o sistema metafísico que emerge dos trabalhos de David Lewis. Esse sistema pode ser decomposto em pelo menos duas teorias. A primeira nomeada como realismo modal genuíno (RMG) e a segunda como mosaico neo-humeano. O RMG é, sem dúvida, mais popular e defende a hipótese metafísica da existência de uma pluralidade de mundos possíveis. A principal razão em favor dessa hipótese é a sua aplicabilidade na discussão de (...) problemas losó cos, esse motivo não será diretamente abordado neste artigo. Pois, o foco está em compreender o mosaico neo-humea- no e como ele relaciona-se com a metafísica de mundos possíveis. Em outras palavras, o meu objetivo é entender as bases losó cas que sus- tentam o realismo modal genuíno. (shrink)

O discurso a respeito dos Mundos Possíveis pode ser uma ferramenta bastante útil para a filosofia. Pode ser útil, por exemplo, para a compreensão das modalidades, da necessidade e da possibilidade. No entanto, para utilizar o discurso dos Mundos Possíveis devemos ter uma explicação satisfatória do caráter ontológico da Semântica dos Mundos Possíveis. Para isso, precisamos responder a questões do tipo: O que é um Mundo Possível? De que forma eles existem? Em quantos Mundos Possíveis podemos falar? Há diversas formas (...) de responder a estas perguntas. Neste trabalho pretendemos apresentar duas teorias que possuem uma abordagem realista para a noção de Mundo Possível. Cada uma dessas teorias atribuiu um caráter ontológico diferente para a noção de Mundo Possível e, portanto, uma metafísica diferente. A primeira delas é o Realismo Modal Extremo, teoria atribuída a David Lewis que defende a existência genuína de uma pluralidade de Mundos Possíveis. A segunda teoria é a teoria combinatória da possibilidade de David Armstrong. Essa teoria é uma versão das teorias do atualismo modal que também são teorias realista em relação à existência de mundos possíveis, mas que dão prioridade ao mundo atual. Por fim, pretendemos comparar as duas teorias e avaliar qual é mais vantajosa levando em consideração o custo ontológico de cada uma delas, (i.e., em relação ao número de entidades postuladas) para termos uma metafísica mais econômica.

This article aims to review the standard objections to dualism and to argue that will either fail to convince someone committed to dualism or are flawed on independent grounds. I begin by presenting the taxonomy of metaphysical positions on concrete particulars as they relate to the dispute between materialists and dualists, and in particular substance dualism is defined. In the first section, several kinds of substance dualism are distinguished and the relevant varieties of this kind of dualism are selected. The (...) remaining sections are analyses of the standard objections to substance dualism : It is uninformative, has troubles accounting for soul individuation, causal pairing and interaction, violates laws of physics, is made implausible by the development of neuroscience and it postulates entities beyond necessity. I conclude that none of these objections is successful. (shrink)

The diversity in agronomic practices being used by sugarcane producers in Brazil determines differences in economic performance and cost structure. The purpose of this study is to evaluate the cost of six systems of agronomic practices using fixed or variable rates for soil amendment, fertilizer, and defensive applications and assess the profitability of these systems at three scales of sugarcane production. We then describe the data sample related to the 2019–2020 harvest season and collected from fifty-five sugarcane producers in the (...) central-south region of Brazil. Thereafter, using a quantitative approach, a cost analysis was performed, and the cumulative frequency of the net revenue for the three scales of production (small, medium, and large), was calculated using a Monte Carlo simulation. The cost analysis indicated that fertilizer had the highest cost considering the agronomic practices adopted at the three scales of production analyzed. The cumulative frequency analysis results from the Monte Carlo simulation showed the highest net revenue per hectare for medium sugarcane producers. In addition, the presence of economies of scale was not confirmed because the lowest cost was found in small-scale sugarcane producers and the highest net revenue was obtained by medium-scale sugarcane producers.

This article discusses the process of universalization of education in Brazil the count from a specific spatiality - the places on the edge of the Transmazonica highway. There being no need toquestion the scope and effectiveness of expanding access to basic education, given its wide acceptance in the country - we start from the principle of geographical connectivity/connection to problematize such educational universalization. We aim to reflect on the scope of basic education, its conditions and ability to potentiate or not (...) the diversity of the territory. Methodologically grounded in a dialogue between phenomenology and existentialism, we conduct a literature review taking as starting point the preliminary empirical research data. We conclude that the universalization of education is configured as extermination argument that effective the urbanocentric vision and one connectedness between places and territory, produces disconnection of the places themselves, removing their ability to communicative action that jeopardizes not only education the local, but regional and national.

The COVID-19 pandemic has brought significant challenges to healthcare systems worldwide, and in Africa, given the lack of resources, they are likely to be even more acute. The usefulness of Traditional African Healers in helping to mitigate the effects of pandemic has been neglected. We argue from an ethical perspective that these healers can and should have an important role in informing and guiding local communities in Africa on how to prevent the spread of COVID-19. Particularly, we argue not only (...) that much of the philosophy underlying Traditional African Medicine is adequate and compatible with preventive measures for COVID-19, but also that Traditional African Healers have some unique cultural capital for influencing and enforcing such preventive measures. The paper therefore suggests that not only given the cultural context of Africa where Traditional African Healers have a special role, but also because of the normative strength of the Afro-communitarian philosophy that informs it, there are good ethical reasons to endorse policies that involve Traditional Healers in the fight against COVID-19. We also maintain that concerns about Traditional African Healers objectionably violating patient confidentiality or being paternalistic are much weaker in the face of COVID-19. (shrink)

In August 2021, Froese et al. published survey data collected from 2,543 respondents on their subjective experiences living under imposed social distancing measures during COVID-19 (1). The questionnaire was issued to respondents in the UK, Japan, and Mexico. By combining the authors’ expertise in phenomenological philosophy, phenomenological psychopathology, and enactive cognitive science, the questions were carefully phrased to prompt reports that would be useful to phenomenological investigation and theorizing (2–4). These questions reflected the various author’s research interests (e.g., technology, grief, (...) time). Between April 7th and July 31st, 2021, a second questionnaire with the same question set was issued to respondents of the original who had agreed to do a follow-up. This was intended to capture subjective reports of life under social distancing measures a year after the initial survey. By this time–depending on their country of residence and health status–respondents had potentially lived with repeated and prolonged lockdowns and a variety of other restrictions on their social lives. When taken together, Survey I and Survey II provide a cross-cultural and longitudinal dataset that allows for analysis of longer-term impacts of imposed social distancing measures on people’s experiences. For researchers working in diverse disciplines, this dataset offers a rich resource that reflects people’s reactions to the imposition of different social restrictions in different countries and over different time periods.

This text is part of an on going research. It deals with the relationship between the production and experience of the places on the edge of the Trans-Amazon Highway (BR 230), which cuts the North and a Northeast portion in the East-West direction. Considering its programmatic sense of occupation of the territory, as opposed to the explanation already accepted, which expresses the road as an engineering system, therefore, means to flow, is that I propose to think the road as an (...) everyday living space, emphasizing the educational dimension to understand the existence of places. My purpose is to analyze the spatial imagination underlying the external understanding to the Trans-Amazon, in the educational plan, regarding the unique geographicity produced by local groups living near the road. Methodologically, I seek a dialogue between a phenomenological design and the existentialism, developing field of research procedures, literature review that supports the concepts of spatial imaginations, place and field education, critical reading of official documents in the MEC sites imagery record in dialogue with the representation of those that live on the edge of “Strip”. As an indication of preliminary findings point out: 1. The denial of places as a geopolitical strategy which is materialized in the educational process and planning politics; 2. The inescapable geographicity of groups that self recognize and are related contradictorily to the Trans-Amazon Highway; 3. The Countryside Education as opening or denial of the place, both for those who live it, and for those who do not live it, which can be ignorance widespread factor in terms of knowledge of the Amazon spatiality or coping and creation of a new geographic and cartographic knowledge about the places cut by “Strip”.

Religions today, actively participate in the daily life of most people on the planet, producing different relationships and conflicts too, from a reference to the transcendent existence, so the construction of their space of action - their territories - cut out ways different society, especially in big cities, where the clash of different world views imply different ways of living and feeling the city and others in this city. We propose here the discussion about territory and identity of the Church (...) of Jesus Christ of Latter Day Saints, more popularly known as Mormons, in Belem, from the phenomenological method, highlighting the experience of church members as central to relational and hierarchical production that territory, so that it becomes a source of affirmation geo-symbolic group in the city and the world. Clarifying the designation of territorial identity and explaining their sacred ways of acting and conceiving the world contributed to deepen the debate in key categories to suit the social sciences in general: space and culture, and also debating and rethinking of the specific concepts geography in their culture perspective.

Objective of the study: To analyze the costs and profits of sugarcane production regarding the cultural practices of sugarcane suppliers. Methodology/approach: This study positions itself in this gap by comparatively analyzing 6 types of cultural practices: unraveling, windrowing, application of correctives, herbicides, insecticides and fertilizers, with the option of two systems Fixed rate (TF) and Variable rate (TV). Originality/Relevance: Brazil is a world reference in sugarcane production, with the State of São Paulo being the largest Brazilian producer. However, for sugarcane (...) suppliers to maintain this activity there is a need to reduce production costs and increase profitability/ha. However, there is a theoretical-practical gap in the financial assessment (costs and profits) of different cultural practices inherent to sugarcane production. Main results: The results demonstrated that the costs of cultural practices represent more than 30% of the total sugarcane production costs. The TF system proved to be more cost-efficient in the following operations: correctives, herbicides and insecticides. In the application of fertilizers, the TV system, in broadcast mode, had the best result. Finally, the profit/ton was R$1.70, demonstrating a very low profit margin/ha given the risk of the activity. Theoretical/methodological contributions: The sample for this research comprised 55 sugarcane suppliers from the State of São Paulo, whose data were obtained through a survey. The comparative analysis was based on the difference in costs of cultural practices and the estimation of the level of certainty (profit/costs), analyzed through the cumulative frequency carried out through the Monte Carlo Simulation (SMC).

The aim of this paper is to clarify the truth-functional interpretation of the logical connective of the material implication. The importance of such clarification lies in the fact that it allows avoiding the supposed paradoxes introduced by C. I. Lewis (1918). I argue that an adequate understanding of the history and purposes of logic is enough to dissolve them away. The defense is based on an exposition of propositional compositionalism. To compare, I also present Stalnaker’s (1968) alternative that seeks to (...) explain the implicit concept of conditionality of conditionals assertions. In order to reinforce my aim I expound the twelve different meanings of ‘implication’ stated by Corcoran (1993) in order to hold that a proper understanding of these meanings allows us to avoid ambiguities and confusions. Finally, I expect to show that despite the possible alternatives, compositionalism is still the best explanation for the truth-functionality account of logical connectives. (shrink)

The costs of agricultural inputs added to those of labor represent almost a third of the total cost of Brazilian sugarcane production. This study analyzes the behavior of the price per ton of sugarcane in Brazil, relating it to the main production costs of this cultivation. Twelve price indicators from January 2015 to December 2020 were evaluated. First, the data were adjusted to a multiple linear regression model to identify the significant variables on variation in the price per ton of (...) sugarcane. Then, the Monte Carlo simulation was used to measure the level of certainty of occurrence of these variables, and forecasts were obtained from the adjustment of ARIMA models. The results showed the influence of the costs of diesel oil, two agricultural pesticides, and daily laborers on the price of sugarcane, besides an increasing trend of its, providing relevant short-term projections for decision-making about investments in the agribusiness sector.

In his Lectures on Fine Art (1835), Hegel emphasizes the grotesque character of Indian art. Grotesqueness results, in his view, from a contradiction between meaning and shape due to the incongruous combination of spiritual and material elements. Since Hegel's history of art is teeming with examples of inadequacy between meaning and shape, this paper aims to distinguish the grotesque from other types of artistic dissonance and to problematize Hegel's ascriptions of grotesqueness to ancient Indian art. In the first part of (...) the paper, I characterize the grotesque by the unnatural distortion of natural shapes with the purpose of achieving a direct sensuous manifestation of an indeterminate and impersonal divinity, Brahman. Such an attempt is, in Hegel's view, self-contradictory and self-defeating, leading to an exaggeration of the conflict between nature and spirit instead of the intended reconciliation between the two parts. In the second part of the paper, I compare Hegel's account of Indian art to the ‘monstrous myths’ of early modern Europe. Unlike his predecessors, Hegel legitimizes the grotesque representations of Hindu gods as endowed with profound meaning and the result of a universal human need, yet he describes them as ultimately irrational and repulsive based on a prejudiced view of the Indian people(s). In this sense, Hegel's assessment of Indian art functions as a reflection of modern European culture, its fascination and horror in the face of what Enlightenment could not entirely purge, rather than as a truthful and objective account of Indian art and culture. By questioning Hegel's characterization of Hindu iconography and mythology, this paper contributes to underexplored areas of Hegelian aesthetics, namely Hegel's account of symbolic art, especially Indian art, as well as his views on negative aesthetic experiences and values.

Para solucionar a questão “sobre o que há” levantada por Quine, e realizar a tarefa de compreender de forma exauriente as muitas unidades ontológicas que povoam a grande província do Ser, propomos como alternativa à ontologia punteliana, uma nova ontologia designada de “Ontologia Estrutural” (OE). Tal ontologia parte de bases teóricas sistemático-estruturais, mas desemboca em uma visão diversa em que co-subsistem unidades factuais estruturadas, configurações estruturais (dinâmicas), bem como unidades ontológicas aparentes (objetos), todas englobadas pela subdimensão temporal que as interconexiona, (...) compreendida esta como uma subdimensão (interna) da macrodimensão do Ser. Nesse sentido, começamos situando a temática ontológica na discussão filosófica atual a partir de uma chave quineana; prosseguimos apresentando um conceito de verdade derivado de nossa leitura da filosofia punteliana, o qual constituirá o ponto de ligação entre linguagem e mundo. Na sequência, mostramos como do conceito de verdade trazido à lume, após uma breve incursão na semântica filosófica, chegamos ao campo ontológico a partir das categorias ontológicas de estrutura e estado ontológico. Ao final, delineamos, em seus caracteres gerais, a nossa ontologia estrutural, compreensiva de noções ontológicas próprias que dão novos rumos à compreensão filosófica desta grande temática.

This article proposes an analysis of the use and value of the terms ‘philosophia’ and ‘philosophus’ in Peter Damian’s works. Despite a remarkable number of ‘negative’ occurrences, the two words are also used in a ‘positive’ sense, especially in the sermo VI, devoted to the figure of Saint Eleuchadius, a pagan philosopher who converted himself to the Christian truth and put his intellectual competencies at the service of the Church. Contradicting the standard image of Peter Damian as ‘anti-dialectician’, Eleuchadius’ case (...) shows how the cardinal-bishop of Ostia could accept the idea of a Christian philosopher, following the Augustinian interpretation of the biblical “Gold of the Egyptians”.

This paper reviews the central points and presents some recent developments of the epistemic approach to paraconsistency in terms of the preservation of evidence. Two formal systems are surveyed, the basic logic of evidence (BLE) and the logic of evidence and truth (LET J ), designed to deal, respectively, with evidence and with evidence and truth. While BLE is equivalent to Nelson’s logic N4, it has been conceived for a different purpose. Adequate valuation semantics that provide decidability are given for (...) both BLE and LET J . The meanings of the connectives of BLE and LET J , from the point of view of preservation of evidence, is explained with the aid of an inferential semantics. A formalization of the notion of evidence for BLE as proposed by M. Fitting is also reviewed here. As a novel result, the paper shows that LET J is semantically characterized through the so-called Fidel structures. Some opportunities for further research are also discussed. (shrink)

Resumo: Neste artigo, apresentamos uma versão de uma teoria que eu chamarei de Contextualismo Epistêmico ‒ a visão de que o contexto e os padrões determinados por ele desempenham um papel central na avaliação de se um agente epistêmico tem, ou não, justificação e, portanto, conhecimento ‒ para tentar resolver um dos problemas mais influentes em epistemologia, a saber, o Problema do Regresso epistêmico. O primeiro passo será o de caracterizar o problema do regresso epistêmico. Em seguida, apresentaremos uma importante (...) distinção que é útil para um melhor entendimento da nossa tese, isto é, a distinção entre justificação proposicional e doxástica. Então, abordaremos as visões tradicionais que supostamente alegam resolver este problema, mostrando que todas são problemáticas. Por fim, apresentaremos a visão que pretendemos defender, mostrando como ela pode oferecer uma resposta ao problema do regresso epistêmico, de uma maneira que as outras visões não podem. Palavras-chave: Regresso Epistêmico, Justificação, Conhecimento, Contextualismo Epistêmico. Abstract: In this paper we present a version of a theory that we will call Epistemic Contextualism - the view that the context and the standards that it determines, play a central role in evaluating whether, or not, a subject has justification, and therefore knowledge - to try to solve one of the most influential problems in epistemology, namely, the Epistemic Regress Problem. The first step will be to characterize the epistemic regress problem. Next, we present an important distinction that is useful to a better understanding of our view, that is, the distinction between propositional and doxastic justification. Then, we present traditional views that allegedly claim to solve this problem showing that all are problematic. The final step concerns the exposition of the view we want to defend, showing how it can solve the epistemic regress problem in a way that the other views cannot.

Resumo O Contextualismo Epistêmico é conhecido por alegar oferecer a melhor resposta para alguns dos principais problemas epistemológicos, dentre eles o problema gerado pelos paradoxos céticos e, por conseguinte, por deter o conhecimento sobre muitas coisas que ordinariamente julgávamos já conhecidas. Da mesma forma, seria uma via capaz de manter a validade do princípio de fechamento dedutivo. O presente texto pretende analisar a teoria contextualista, conforme apresentada por Stewart Cohen, mostrando como o contextualismo resolve essas questões. Na primeira parte do (...) texto apresentaremos alguns problemas (e algumas características históricas) que culminaram no surgimento do contextualismo. Na segunda parte explanaremos a teoria contextualista de Cohen. Em seguida levantamos algumas objeções comumente endereçadas ao contextualismo. Por fim, concluímos que, embora não seja completamente refutada, a teoria contextualista deve dirimir dúvidas e explicar algumas dificuldades para manter a sua plausibilidade. Palavras-Chave: Contextualismo; Ceticismo; Conhecimento; Stewart Cohen. -/- Abstract Epistemic Contextualism is known by his allegation to possess the best answer to some of the major epistemological problems, among them, the problem created by the skeptical paradoxes and therefore the claim that we can know many things we ordinarily claim to know, and also maintains the validity of the closure principle. This paper seeks to examine Contextualism, as presented by Stewart Cohen, showing how Contextualism solves these problems. In the first section of the text I will present some problems (and some historic features) that originated Contextualism. In the second section I will present the Cohen`s Contextualism. Then, we consider some objections raised against the contextualista theory. Finally, we conclude that although these objections are not able to completely refute contextualism its proponents have to give better explanations in order to maintain its plausibility.

Resumo: No livro When is Knowledge True Belief? (2012), Richard Foley apresenta uma teoria do conhecimento bastante simples e original, que pretende desbancar as rivais e reorientar a teoria do conhecimento: um sujeito S sabe alguma proposição p se e somente se S verdadeiramente crê que p e não lhe falta nenhuma informação importante. Michael Hannon, em seu artigo “Is Knowledge True Belief Plus Adequate Information?” (2013), faz uma objeção à visão de Foley, acusando-o de oferecer um argumento circular que, (...) ao não diferenciar informação importante de informação não importante, acaba, em última instância, por fazer referência à própria noção de conhecimento. Acredito que a teoria apresentada por Foley está no caminho certo; porém, apresenta- se de forma incompleta. Neste artigo, apresento uma interpretação subjetivista de relevância epistêmica, proposta originalmente por Floridi, que complementa a visão proposta por Foley e rechaça as objeções levantadas por Hannon. Palavras-chave: Conhecimento. Informação. Relevância. -/- Abstract: In When is Knowledge True Belief? (2012), Richard Foley offers an original and extraordinarily simple theory of knowledge which intends to overcome its rivals and reorient the theory of knowledge: a subject S knows some proposition p if and only if S truly believes that p and does not lack any important information. Michael Hannon, in his article “Is True Belief Knowledge Plus Adequate Information?” (2013), puts forward an objection to Foley’s view which charges him of offering a circular argument that fails to distinguish important information from unimportant information without ultimately making reference to knowledge. I believe the theory presented by Foley is on the right . (shrink)

Resumo: Neste texto, introduzo algumas questões importantes que fazem parte do debate sobre infiltração pragmática. Além de apresentar e problematizar as principais alegações oferecidas pelos proponentes da infiltração pragmática eu irei contrasta-la com algumas teses mais tradicionais, como a Tese Tradicional sobre o Conhecimento e o Contextualismo Epistêmico. Por fim, apresento uma crítica aos proponentes da infiltração pragmática que parece ainda não ter sido tratada. Concluo que embora controversa, tal tese está longe de ser refutada completamente. Palavras-chave: Conhecimento; Contexto; Justificação; (...) Padrões; Infiltração prática. -/- Abstract: In this paper I introduce some central aspects concerning the debate on pragmatic encroachment. After introducing and discussing the main arguments offered by the pragmatic encroachers advocates I will contrast it with more traditional theses such as the Traditional Analysis of Knowledge and Epistemic Contextualism. Finally, I present an objection to the pragmatic encroachment approach that haven't been treated yet. I conclude that despite its difficulties, the pragmatic encroachment view is far from being refuted. Keywords: Knowledge; Context; Justification; Standards; Pragmatic encroachment. (shrink)

Partindo do cenário atual das sociedades de inimizade, tal como teorizado por Achille Mbembe, este texto segue os argumentos de bell hooks para pensar em uma política do amor que possa aparecer como um antídoto para os males causados pelas sociedades da inimizade que se sustentam em uma imagem da alteridade experimentada desde a figura do inimigo a ser combatido, mortificado, morto. Ao valorizar o amor como uma prática - e não somente como sentimento - que envolva o cuidado, a (...) responsabilidade, afeto, reconhecimento, confiança, respeito, comunicação franca, sustentamos a necessidade da construção de outro modelo de sociedade guiado pela prática do amor, as sociedades do amanhã, que apresente para a experiência das pessoas negras, rotineiramente violada pelo racismo, outro jeito de estar no mundo, considerando o espírito, entendido por Sobonfu Somé como dimensão da existência que necessita do caráter coletivo das relações, como pilar incontornável.
