Peirce’s architectonics, far from rigid, is bended by many plastic transformations, deriving from the cenopythagorean categories, the pragmaticist (modal) maxim, the logic of abduction, the synechistic hypotheses and the triadic classification of sciences, among many other tools capable of molding knowledge. Plasticity, in turn, points to interlacements between mathematics and art, and shapes some associated conceptual forces in the boundary of the disciplines: variation, modulation and invariance; transformability, continuity and discreteness; creative emergence. In this article we focus on this third (...) aspect, through bounded, well defined case studies in the Logic Notebook. The first section describes the manuscript and its interest for a study of creativity, leading to a short speculation on “creative reason” and “plastic imagination” in Peirce. The second section studies five precise cases of creative emergence in the Logic Notebook: differential relatives, existential graphs, sequence diagrams, triadic logic, translatability. Some major surprises occur in those detailed studies. (shrink)

Koopman’s book revolves around the notion of transition, which he proposes is one of the central ideas of the pragmatist tradition but one which had not previously been fully articulated yet nevertheless shapes the pragmatist attitude in philosophy. Transition, according to Koopman, denotes “those temporal structures and historical shapes in virtue of which we get from here to there”. One of the consequences of transitionalism is the understanding of critique and inquiry as historical pro...

This paper explores the intertwinement of ontology and history that happened after the idealist turn of Kantian transcendentalism, particularly in classic German idealism and later in American pragmatism. The paper focuses on the less remarked-upon consequence of this intertwinement, namely the possibility of a new reading of history based on changes in concepts and habitual mentality. The paper proposes a new take on historiography that vindicates Hegel’s insight but changes his approach to a pragmatist one, more apt to face historical (...) changes in a technical way and less easily twistable into ideological frameworks. The paper argues that the notion of habit, as phenomenologically and semiotically described by Peirce, is the fundamental cellule of the pragmatist take on the entanglement of history and ontology. The paper elaborates on the notion of habit, singling out a special form of it called “gesture” that can be a useful tool for reading the history of the human spirit without incorporating Hegel’s dialectic and Absolute. The paper compares the notion of gesture as it originated in the pragmatist tradition with the parallel use of the term in the early studies of Michel Foucault and argues that the notion of gesture is better equipped to tackle a theoretical reading of history.

“Comprendre est en attraper le geste, et pouvoir continuer”(J. Cavaillès) “The general theory of signs fails essentiallyif it does not encompass a philosophical account of gesture” (Colapietro 2016: 170) Let me first thank Rosa M. Calcaterra and Roberto Frega, co-directors of the European Journal of Pragmatism and American Philosophy, who were so kind to organize this symposium. I also thank all contributors and Matteo Santarelli who edited the whole work. It is a great honor to me that such...
