History of Euler-Venn-Diagrams is a research project that is located at the FernUniversität in Hagen. The aim of the project is a systematic review of the research cultures of logics using Euler- and Venn-like diagrams. Particular attention is given to the years between 1550 and 1880 and to the comparison of these logics with modern diagrammatic approaches.
A current research example concerns the thesis Schopenhauer’s Logic, Geometry and Philosophy of Language are based on (Euler-type) diagrams. See the current CfP or the following articles:
