- Speaker: Frank Sautter "A Bunch of Diagrammatic Methods for Syllogistic" This paper presents, assesses, and compares six diagrammatic methods for Categorical Syllogistic. Venn’s Method is widely used in logic textbooks; Carroll’s Method is a topologically indistinguishable version of Venn’s Method; and the four remaining methods are my own: the Dual of Carroll’s Method, Gardner’s Method, Gardner–Peirce’s Method, and Ladd’s Method. These methods are divided into two groups of three and the reasons for switching from a method to another within each group are discussed. Finally, a comparison between the Dual of Carroll’s Method and Ladd’s Method supports the main result of the paper, which is an approximation of the two groups of methods. - Chair: Itala D’Ottaviano Member of the Editorial Board of LU - Associate Organization: Brazilian Logic Society, presented by its president, Cezar Mortari Registrate here to attend this LUW session: https://www.springer.com/journal/11787/updates/18988758
