By explaining these 4 kinds of categorical syllogism types each syllogism can be identified, which is also called “stating the mood of an argument”. We know syllogisms always consist out of a major and minor premise and a conclusion. In standard form, as shown on this page, the major premise is always shown first, after which the minor premise and the conclusion follow. An example of a mood of a categorical syllogism could be: AEO. We now know that the major premise is of type A (all A are B), the minor premise is of type E (No A is B) and the conclusion is of type O (some S is no P).
