Abstract

In this article, I lay out a new type of logic graph that can replace Euler and Venn Diagrams. This new form of logic graphs I call “class-tables” (or “c-tables” for short). I show how c-tables can be used easily to assess standard syllogisms. I then show how c-tables can be used to directly assess class arguments involving named individuals, as well as to assess extended syllogisms, i.e., syllogisms of more than three classes. I end by illustrating how c-tables can also easily handle syllogisms with compound classes.
