Os signos e as classes dos signos estão entre os tópicos mais importantes do sistema filosófico de Charles S. Peirce. As 10, 28, e 66 classes de signos são classificações desenvolvidas especialmente a partir de 1903 e representam um grande refinamento da divisão fundamental de signos – ícone, índice, símbolo. Nossa abordagem aqui define uma estratégia de visualização das classificações dos signos, com especial atenção para as 10 e 66 classes de signos. O livro está dividido em duas partes: (i) (...) bases teóricas, (ii) diagramas para as classes de signos. Na Parte I (bases teóricas), são apresentadas introdutoriamente as noções fundamentais das categorias fenomenológicas, classes de signos, as tricotomias e diagramas, assim como implicações gerais de nossa abordagem, metodologia e aplicações. Na Parte II (diagramas para as classes de signos), são apresentados e discutidos os modelos das classes, propostos por Peirce e seus comentadores, incluindo uma introdução detalhadamente documental de nossos modelos, 10cubes e 3N3, diagramas dinâmicos para as classes de signos.

A close reading of Descartes’ works, particularly his Regulae ad Directionem Ingenii, calls into question the common interpretation of Peirce’s ‘Questions Concerning Certain Faculties Claimed for Man’ and ‘Some Consequences of Four Incapacities’ as being anti-Cartesian. In particular, Descartes’ conception of intuition differs from Peirce’s, and on one plausible reading of Descartes his intuitionism actually mirrors Peirce’s inferentialism in key respects. Given these similarities between Descartes and Peirce, the dogmatic status of the anti-Cartesian interpretation of Peirce becomes evident.

This article contends that Charles Sanders Peirce (1839–1914) may enhance our understanding of educational beliefs and that Peirce’s logic may be a tool to distinguish between a dogmatic and a pragmatic justification of such beliefs. The first part of the article elaborates on Peirce’s comprehension of beliefs as mediated, socially situated and future-oriented. The second part points to how Peirce promotes his “method of inquiry” as an ethos of science. The method is not judged by the conclusions it lead to (...) or by the knowledge it may produce. Contrary, as the results are unavoidably provisional and rectifiable, Peirce holds the method productive due to the norms guiding the inquiry: (1) the pragmatic principle, (2) the social principle, (3) fallibilism and (4) abduction. In sum, when adopting a peircean conception, educational research, theory building and practice should be characterized as a mutual commitment towards shared processes of joint learning. In that, Peirce’s method of inquiry may be fruitful in sorting dogmatism from pragmatism. (shrink)

The state of theorizing bearing on an explicit, contemporary, critical theory of society is first of all outlined. While contemporary conditions of scholarship are not promising in this respect, the potential of a distinctive critical theory of society nonetheless remains tantalizing. The mostly agreed, even if mostly only implicitly, core architectonic of critical theory is outlined as a foundation, though disagreements persist over the significance of the linguistic turn and context-transcendent versus context-immanent modes of theorizing. On the basis of the (...) outline of the general architectonic, suggestions are made, pointing forward to the articles in the special issue, as to how the contemporary democratic focus of the theory offers inspiration for a more explicit, modern articulation. Such a theory would follow the lead of the first generation, but it would additionally take on board the multiple theoretical as well as social changes that have since occurred. (shrink)

The paper tracks the major changes Peirce brought to the classifications of signs in the Harvard Lectures on Pragmaticism, and the Lowell Lectures, both of 1903. These changes turn on the discovery of the need to include in the theory of signs an account of the thinghood and the eventhood of signs. This discovery becomes the “First Trichotomy” of the classification into three trichotomies and ten classes. It investigates the significance of these changes, both for the scope of sign theory, (...) and for the function sign theory has to play in the mature pragmatism. (shrink)

This article argues that there is a marked ambivalence in Habermas’ concept of intersubjectivity in that he wavers between an interactionist and a discursive understanding. This ambivalence is demonstrated with reference to his recent critique of Robert Brandom's normative pragmatic theory of discursive practice. Although Habermas is a leading theorist of discourse as an epistemically steered process, he allows his interpretation of Brandom's theory as suffering from objective idealism to compel him to recoil from discourse and to defend a purely (...) interactionist or dialogical position. It is argued that the ambivalence in question is related to Habermas’ incomplete theorization of communication as a process of structure formation that unfolds sequentially through time on different levels. His architectonic of communicative intersubjectivity is marred by a missing concept. His characteristic concept of coordination is insufficient and must be complemented by a concept of synthesis at the discursive level. Key Words: Brandom • communication • coordination • discursive • synthesis • Habermas • Luhmann • objectivism • process • sequentiality • structure formation • time. (shrink)
