Definition: In logic, a form of deductive reasoning consisting of a major premise, a minor premise, and a conclusion. Adjective: syllogistic. Here is an example of a valid categorical syllogism: Major premise: All mammals are warm-blooded. Minor premise: All black dogs are mammals. Conclusion: Therefore, all black dogs are warm-blooded. In rhetoric, an abridged or informally stated syllogism is called an enthymeme.
In the above example, the argument form is EIO-4. Quite often, categorical syllogisms are not presented in the standard form. To use the Venn Diagram method to decide their validity, we need to first change them into the standard form.
