Charles Peirce innovated an extension of Euler diagrams to incorporate negative terms through novel star-shaped curves, representing negation and dualizing the relation of inclusion to express exclusion. The study (by me and Ahti-Veikko Pietarinen) demonstrates the equivalence of Peirce’s extended Euler diagrams (PED) with the axiomatic system Atl, which is based on Christine Ladd-Franklin’s work on exclusion relations. The PED system is shown to be capable of expressing all fifteen valid syllogisms, thereby streamlining logical reasoning. By taking exclusion as primary, Peirce’s advancements are connected to Ladd-Franklin’s earlier work, highlighting the simplification of syllogistic reasoning and the historical evolution of Eulerian diagrammatic logic.

Mr Fangzhou Xu 许方洲, a doctoral candidate of University of Chinese Academy of Social Sciences, has published two articles. His master thesis is on Ladd-Franklin’s Antilogism, reviewing its historical developments, proposing an axiomatic system Atl based on Ladd-Franklin’s exclusion relation, with more details. Recently he is studying philosophical logics, especially First- and Higher- Order Logic, and Modal logic.

This talk indicates the intersections between Japanese kata as an embodied practice which not only inculcates a collection of skills, but also inculcates ethical principles, and John Dewey’s understanding of habit. In theJapanese context, kata are essential for the mastery and embodiment of Do, or “ways” of being in the world. Insofar as this is thecase, kata themselves serve to align individuals with distinct Do, as ways of being in the world, through how they inculcate specific embodied practices into their practitioners. This process of inculcation bears a striking resemblance to John Dewey’s understanding of habit insofar as habit, like kata, serves to organize the body in line with particular dispositions towards actions which are what enable individuals to “have” a world. Further, as habit is the essential elements of customs, and customs are the ways in which cultures“have” a world for Dewey, placing Japanese kata and Do in conversation with Dewey’s theory of habit, culture, and custom can indicate the ways in which individual cultures have their own Do, or ways.

Dr Johnathan Flowers is Assistant Professor of Philosophy at California State University, Northridge. Flowers’s research areas include African American intellectual history, Japanese aesthetics, American pragmatism, philosophy of disability, and philosophy of technology. Flowers also works in the areas of science and technology studies and comics studies, where he applies insights from American pragmatism, philosophy of race, and philosophy of disability to current issues in human-computer interaction, artificial intelligence and machine learning, and representations of identity in popular culture. His first monograph, Monono Aware and Gender as Affect in Japanese Aesthetics and American Pragmatism, was published by Lexington Books in 2023.

I believe that there are important similarities between Buddhist and pragmatist philosophies that have not been identified yet. In particular, I will examine the Buddhist doctrines of  śūnyatā, idaṃpratyayatā, and anātman, on the one hand, and the pragmatist doctrines of anti-essentialism,  process ontology, and synechism, on the other. According to the doctrine of  śūnyatā  (emptiness, void), phenomena have no permanent essence; they simply continually transform into each other. This coincides with the anti-essentialism of the classical pragmatists. According to the doctrine of idaṃpratyayatā (conditionality), all phenomena arise from conditions. Then the conditions arise from their conditions, and so on, ad infinitum. That seems to entail a process ontology. Of the classical pragmatists, Peirce crafted evolutionary cosmology, which is a process ontology, according to which even laws of nature have evolved. According to the doctrine of anātman, there is nothing to the self that does not reduce to the five senses. Here the pragmatist counterpart is different: Peirce and Dewey argued that there is nothing to the self that does not reduce to habit.

Dr Lindholm holds an MSc degree in control engineering and a PhD degree in philosophy. He has recently defended his PhD thesis, according to which knowledge is practice. He studies rational worldview from the standpoint of fallibilism, pragmatism, naturalism, philosophy of technics, and philosophy of economics. His ideas include cybernetic epistemology, technics as hermeneutics, and the potential practice-ladenness of all experience.

Scholars of the history of philosophy of science read and hear a lot about Duhem, Mach, Poincaré, and the members of the Vienna Circle. C.S. Peirce, however, is not generally considered a canonical figure in the history of philosophy of science. But in the early years of the logical empiricist movement in the United States, Peirce received a warm reception from prominent representatives, proponents, and sympathizers of logical empiricism including Charles Morris, Ernst Nagel, Herbert Feigl, and Phillip Frank. This reception was short-lived though and Peirce gradually disappeared from the mainstream philosophy of science while logical empiricism turned into a formidable movement.

In this talk, I begin by discussing some examples of the early reception of Peirce’s philosophy in the works of Morris, Nagel (and his student Justus Buchler), Feigl, Reichenbach, and Frank. These examples show a persistent and gradually refining engagement with various topics in Peirce’s philosophy of science from the late 1920s to the mid-1950s. I then offer some evidence for the eventual marginalization of Peirce in the mainstream philosophy of science and provide some explanations for it.
