Document Summary
Categorical logic: a form of logic whose focus is categorical statements, which make assertions about categories, or classes, of things. A deductive argument form and the ultimate goal is the evaluation of arguments. Categorical statements: a statement or claim that makes a simple assertion. In categorical logic the primary tools are diagrams and calculation rules about categories, or classes, of things. They say how certain classes of things are, or are not, included in other classes of things i. e. all cows are vegetarians, no gardeners are plumbers, some businesspeople are cheats, etc. Reasons why categorical logic is still around: The words in categorical statements that name classes, or categories, of things are called terms. Subject term: the first class, or group, named in a standard-form categorical statement (s) Predicate term: the second class, or group, named in standard-form categorical statement (p) For simplicity, the terms in these statements about cats are single words, just nouns naming a class.
