1. Sob o signo de Descartes, diálogos sobre filosofia moderna.

Uma concepção de cosmopolitismo, de base eurocêntrica, é questionada por pensadores como K. A. Appiah, Walter Mignolo, Silviano Santiago entre outros, para buscar possíveis ressemantizações do termo no contexto contemporâneo, marcado pela globalização, pelo multiculturalismo e pela expansão das novas tecnologias de comunicação. Considerando esse confronto de noções de cosmopolitismo, indaga-se como se deu a interpretação do Brasil no início do século XX, quando recrudesceram as tensões entre cosmopolitismo e nacionalismo. Busca-se, por outro lado, confrontar tais interpretações com as que (...) surgem no início do século XXI, quando a nação vai deixando de ser o centro de um sistema de significação, em tempo heterogêneo e de globalização, em que se pode falar em “cosmopolitismo do pobre” (cosmopolitismo do subalterno), como formulou Silviano Santiago.

This article is a belated contribution to a Common Knowledge symposium on the “unanticipated conceptual practice” of “anthropological philosophy.” The basic argument is that the groundwork for this emerging approach, associated foremost with Eduardo Viveiros de Castro's book Métaphysiques cannibales of 2009, was laid in the 1970s by the controversial French anthropologists Pierre and Hélène Clastres. It is argued that the Clastres took the intellectual practices of Guarani shamans and prophets as analogous to the those of ancient Greek philosophers but (...) also as sharply critical of the principles that underlay early Western metaphysics.

Annotated logics were introduced by V.S. Subrahmanian as logical foundations for computer programming. One of the difficulties of these systems from the logical point of view is that they are not structural, i.e., their consequence relations are not closed under substitutions. In this paper we give systems of annotated logics that are equivalent to those of Subrahmanian in the sense that everything provable in one type of system has a translation that is provable in the other. Moreover these new systems (...) are structural. We prove that these systems are weakly congruential, namely, they have an infinite system of congruence 1-formulas. Moreover, we prove that an annotated logic is algebraizable (i.e., it has a finite system of congruence formulas,) if and only if the lattice of annotation constants is finite. (shrink)

There is a debate in philosophy and cognitive science over whether concepts – the building blocks of thought—are couched in a perceptual modality or are amodally represented. The empirical evidence so far collected seems not to have adjudicated this question yet, as reinterpretation of the same set of evidence by both supporters of modalism and amodalism have been provided. I offer a critique of such reinterpretations, arguing that they ultimately derive from theoretical problems in the definition of a modal representation. (...) In particular, I will review three criteria which have been offered to distinguish amodal concepts from modal ones: the isomorphism criterion, the neural location criterion, and the input specificity criterion. I will explain how these criteria often lack theoretical clarity, making it possible in most cases to propose a parsimonious explanation of the same set of data from both an amodalist and a modalist perspective. As a result, it becomes impossible to empirically discriminate between the two interpretations. My conclusion is that the main problem with the discussed criteria is that they frame the question on the format of concept as an either/or debate, by overlooking more interesting empirical questions.

We introduce a family of matrices that define logics in which paraconsistency and/or paracompleteness occurs only at the level of literals, that is, formulas that are propositional letters or their iterated negations. We give a sound and complete axiomatization for the logic defined by the class of all these matrices, we give conditions for the maximality of these logics and we study in detail several relevant examples.

Neste artigo, examino a duplicidade de sentidos que a tese pluralista “os seres são múltiplos” ou “se há múltiplos seres” comporta: pode significar uma multiplicade numérica, isto é: a tese de que há mais de uma coisa no mundo, assim como pode significar que uma mesma coisa possui mais de um atributo. Incialmente, argumento que Sócrates estava consciente desta ambiguidade, pois as duas compreensões de pluralismo representam perspectivas complementares de uma mesma posição filosófica. Segundo minha interpretação, o reconhecimento dessa ambiguidade (...) permite melhor entender a crítica de Sócrates ao monismo eleático, sua defesa da Teoria das Ideias e sua distinção entre Formas transcendentes e propriedades imanentes. Estes dois sentidos de multiplicidade farão ainda parte da estratégia utilizada por Parmênides na sua contra-argumentação à solução socrática ao paradoxo de Zenão. (shrink)

In this paper, I defend that the historiographical category of eclecticism is a correct way to describe the epistemology and the exegetical activity of the Anonymous commentator on Plato’s Theaetetus. In addition, I show that the interpretation of the platonic philosophy presented in this text not only presupposes an eclectic philosophical attitude, but also offers a conscious defense of a positive and philosophically relevant form of eclecticism. By eclecticism, I understand a method of inquiry based on the deliberate use of (...) hypotheses and arguments from different philosophical traditions. My claim is that Anon. intends to lay ground of his way of doing philosophy by attributing it to Plato and the platonic tradition. In doing so, Anon. provides us with a positive understanding of eclecticism as a legitimate methodology of philosophical investigation. (shrink)
