TL;DR: An effort to sketch an alternative that does not rely primarily on peer pressure, which draws on the work of C. S. Peirce to show that some manipulations are barred by the self-same nature of the diagrams, which is a good (non-social) reason to regard some reasoning as bad.
Abstract: Robert Brandom holds that what we mean is best understood in terms of what inferences we are prepared to defend, and that such a defence is best understood in terms of rule-governed social interactions. This manages to explain quite a lot. However, for those who think that there is more to making correct/incorrect inferences than obeying/breaking accepted rules, Brandom’s account fails to adequately capture what it means to reason properly. Thus, in an effort to sketch an alternative that does not rely primarily on peer pressure, I draw on the work of C. S. Peirce. Peirce argued that, when we reason, we manipulate abstract diagrams in order to observe what results. Since some manipulations are barred by the self-same nature of the diagrams, I try to show that this qualitative incompatibility, which I dub “contrapiction,” is a good (non-social) reason to regard some reasoning as bad.
TL;DR: A framework for “improvisational” social acts and communication is introduced by referring to the idea of “relationalism” such as natural farming, permaculture and deep ecology and the notion of Existential Graph is introduced.
Abstract: A framework for “improvisational” social acts and communication is introduced by referring to the idea of “relationalism” such as natural farming, permaculture and deep ecology. Based on this conception, the notion of Existential Graph by C. S. Peirce is introduced. The notion of extended self in deep ecology is substantiated based on the Roy Adaptation Model in Nursing Theory and Narrative approaches. By focusing on Leibnizian notions of space and time and by introducing Petri net, a spatio-temporal model of improvisation is constructed. This model is expected to substantiate the interesting notion of “Ba” proposed by H. Shimizu reflecting Japanese culture.
TL;DR: In this paper, the authors study the ways in which Peirce's pragmatic analysis of propositions resembles game-theoretical semantics, and existential graphs show what they mean by displaying the structure of the semantic game for the proposition represented by a graph.
Abstract: Abstract In the 1890s, Peirce reformulated quantification theory by expressing it in a language of diagrams, called existential graphs. Peirce thought that the iconicity of his graphs made them suitable for analyzing logical reasoning. Iconic signs can be said to show their meaning, and this paper studies the ways in which graphs do this. Peirce's pragmatic analysis of propositions resembles game-theoretical semantics, and existential graphs show what they mean by displaying the structure of the semantic game for the proposition represented by a graph.
TL;DR: The fundamental structures of coexistential communication are formalized as co-creation of Leibnizian space and time in such a manner that they are used to link the communicated messages, thus establishing the “coexistential atmosphere and field” (“Ba” in Japanese) among the individuals.
Abstract: This paper proposes deep and fundamental structures of communication among persons in a “coexistential” setting. The basic framework for this formalization of communication structures is Leibnizian notions of space and time together with the notion of the Existential Graph by C. S. Peirce and that of the Petri net, more precisely, the occurrence net. The fundamental structures of coexistential communication are then formalized as co-creation of Leibnizian space and time in such a manner that they are used to link the communicated messages, thus establishing the “coexistential atmosphere and field” (“Ba” in Japanese) among the individuals. This framework is then applied to the analysis of theater play communication. Finally, the framework of information edaphology is also introduced to discuss the growth processes of individuals and communities through coexistential communication.
TL;DR: Peirce was a man of obsessions as discussed by the authors and although his whole style of thinking and writing was non-systematic, it was never erratic, as it has sometimes been argued.
Abstract: Peirce was a man of obsessions. And, although his whole style of thinking and writing was non-systematic, it was never erratic, as it has sometimes been argued. Fundamentally it was obsessive, and only apparently diffuse and disperse. His enormous curiosity often leads us astray. But, no matter how esoteric or capricious his interest may appear, his work always sheds an unexpected light on some basic and enduring issues. The synthetical dimension of reasoning is one of them. Another, closely linked to it, is the issue of vision and color.
