Definition of a categorical syllogism is an argument with two premises: one syllogism and one conclusion. Let's look at some examples of categorical syllogisms. This handout outlines a way to convert categorical syllogisms into hypothetical syllogisms, the validity of which you should already know how to determine. A categorical syllogism is said to be in standard form when its premises and conclusion are all standard-form categorical propositions and are arranged in a specified standard order. One can readily assess their validity by thinking of universal categorical statements as expressing conditionals. 2. A good leader has the confidence of his followers; Joe Doe, though, does not have the confidence of his followers, and is therefore not a good leader.

So long as the premises of the syllogism are true and the syllogism is correctly structured, the conclusion will be true. As we know, our first example about roses was a categorical syllogism. Determining validity of Categorical Syllogisms There are two ways to determine whether a categorical syllogism is valid or invalid. Important Definitions Major term: the predicate term of the conclusion Minor term: the subject term of the conclusion Major premise: the premise containing the major term Minor premise: the premise containing the minor term Syllogism: any deductive argument . A formal argument's deductive scheme consists of a main and minor premise, as well as a conclusion. Let's look at some examples of categorical syllogisms.

It will also teach you to understand the functioning of these phrases using a device called a "Venn Diagram . A valid syllogism is one in which the conclu- sion must be true when each of the two premises is true; an invalid syllogism is one in which the conclusions must be false when each of the two premises is true; a neither valid nor invalid syllogism is one in which the conclusion either can be true or can be false when . 2.

To specify that order, it will be useful to explain the logician's special names for the terms and premises of categorical syllogisms.
