“Como duas mentes podem conhecer uma única coisa” é um dos textos que Wil-liam James (1842-1910) pretendia reunir sob o nome de Ensaios sobre empirismo radi-cal, embora nunca tenha chegado a ver o projeto concluído. Trata-se da obra tardia do autor, quando este passou a desenvolver algumas das ideias que já se encontravam, em muitos casos de forma embrionária, no monumental Princípios de psicologia. “Como duas mentes podem conhecer uma única coisa” é um dos textos mais importantes desse esforço, uma (...) vez que explica, de forma clara e elegante, um dos pilares do empirismo radical. Como o título já diz, James pretende mostrar como algo pode ser conhecido por duas mentes sem que haja aí uma duplicação, ou um recurso à noção de representação como duplicação de um objeto físico. James postula o conceito de experiência pura e indivisa que se desenvolve em estados de experiências momentâneas sucessivas. A experiência pura acrescenta a consciência à percepção de objetos. Nessa experiência indivisível ocorrem “apropriações” conscientes — que se dão de forma retroativa — das sensações dos objetos pelos sentidos. A consciência conquistada nessa apropriação marca a subjetivação e se dá a partir da inserção do algo sensível, resultante da relação com um objeto físico, na experiência individual. No instante da experiência pura, o objeto é ao mesmo tempo objetivo e subjetivo, não ocorrendo uma duplicação ontológica. Aí reside a resposta à pergunta posta no título: é possível sentir objetos sem duplicá-los. (shrink)

O presente artigo disserta sobre duas características centrais ao holismo epistemológico de Willard Quine: a sustentação de critérios empíricos de avaliação por meio das sentenças observacionais e a defesa de que a ontologia fisicalista é decisiva para a avaliação de teorias.

In Linguistic Bodies, Ezequiel A. Di Paolo, Elena Clare Cuffari and Hanne De Jaegher propose a dialectic method to explain organism’s movements and exchanges, i.e., life inter-actions and evolution, that can also explain the evolution from life to cultural relations, that include linguistic interactions. One of the main questions Linguistic Bodies wants to answer is how to explain human life and culture without a reductive scientific thought. If one defies radical reductionism, one of the central risks is to dissociate physical (...) inquiries from biological investigations. In the book, the authors oppose the analytical mode of thinking present in many natural sciences to a dialectical mode of thinking that would explain living beings’ interactions. It is relevant to question if they succeeded in defending the dialectical model they profess to be the best suited to explain human social phenomena. Following this line of rationale, in this paper, I will, first, show that dialectical methods are over-ambitious and, second, inquire into the anti-reductionist attitude present in the dialectical model advocated in Linguistic Bodies.Key-words: Linguistic bodies, radical reductionism, dialectical model.

Este trabalho visa analisar criticamente as posições epistemológicas hegelianas apresentadas no seu livro Ciência da Lógica, posições essas que dependem primordialmente da aceitação da validade do método dialético.

This paper is an analysis of some aspects of the constitutional system of Carnap's Logische Aufbau der Welt. It considers two possible interpretations of the autopsychological basis - the elementary experiences - as this concept is used in Carnap's book. Some authors, like Michael Friedman and Moulines, see the Aufbau as a structural system whose forms are not determined by basic experiences - elementary experiences. Others, as for instance Stegmüller, say that the structures, the definitions, within the Aufbau are the (...) result of relations which can be established among those experiences. Following the arguments of these interpreters as well as Carnap's epistemological proposal, I sustain in this paper that it is necessary to think about the autopsychological basis - the elementary experiences - as determining Aufbau's structural relations.

In this paper, I argue in favor of a view on the nature of the human mind that is neither a reductionist physicalism nor any kind of dualism, whether of substance or property. I support neutral perspectivism, inspired by neutral monism, with a scientific and materialist content, which allows for the inclusion of conscious phenomenal experiences as part of causal chains of perceptive, emotional, cognitive and deliberative processes. Although there are still no theories, laws and data that allow a final (...) decision on the role of conscious phenomenal experiences in physical-chemical processes in the body, evidence collected in recent decades does not only strengthen our belief in the correlation between physical-chemical events and qualitative conscious experiences but also increases the number of reasons in favor of the thesis that these experiences do have an important functional role in the processes of collection and use of information by the organism.
