Description logics (DLs) are a well-understood family of knowledge representation (KR) languages. The notation of DLs has the flavour of a variable-free first order predicate logic. In this paper, a diagrammatic representation of the DLALC, based on Peirce’s existential graphs, is presented, and a set of transformation rules on these graphs is provided. It is proven that these rules form a soun...

‘Scientific community’ is common currency in the study of science, largely due to Kuhn’s use of the term in his highly influential book The Structure of Scientific Revolutions. As this article explains, however, ‘scientific community’ was not of Kuhn’s coining. It was hinted at by Peirce, and expressly designated by Royce. On a few occasions Fleck affirmed a scientific community, while Polanyi ...

J. W. Peirce (2007, p. 1) has proposed that saturating contrast-response functions in V1 and V2 may form "a critical part of the selective detection of compound stimuli over their components" and that supersaturating (non-monotonic) functions allow even greater conjunction selectivity. Here, we argue that saturating and supersaturating contrast-response functions cannot be exploited by conjunct...

This paper suggests that the sociological analysis of economic life may be improved by drawing on the theory of signs as developed by philosopher Charles Peirce. I take my point of departure from Georg Simmel’s essay “Sociology of the Senses” (1907) and raise the question if an economic sociology of the senses is possible and, if so, what it would look like. The different ways in which the sens...

In his 1903 Syllabus, Charles S. Peirce makes a distinction between icons and iconic signs, or hypoicons, and briefly introduces a division of the last ones into images, diagrams and metaphors. Peirce scholars have tried to make better sense of those concepts by understanding iconic signs in the context of the 10 classes of signs described in the same Syllabus. We will argue, however, that the ...
