History and Philosophy of Euler-Venn-Diagrams is a research project that is located at the FernUniversität in Hagen. The aim of the project is a systematic analysis of logic systems using Euler- and Venn-like diagrams. Particular attention is given to logic diagrams in (early) modern logic and to the question of their modern application.
