On the Origin of Venn Diagrams

Abstract In this paper we argue that there were several currents, ideas and problems in 19th-century logic motivated John Venn to develop his famous diagrams. To end, first examine the problem of uncertainty or over-specification syllogistic became obvious Euler 19th century, numerous logicians tried solve problem. The most was attempt introduce dashed circles into solution developed for problem, however, came from a completely different area logic: instead orienting like diagrams, applied Boolean algebra improve visual reasoning. Venn’s contribution solving elimination also played an important role. result development is still known today as ‘Venn Diagram’.
