Valid Argument Forms

A valid argument form is one that produces true conclusions if the premises provided to it are true. In logic, argument forms serve to provide and verify the structures of arguments that are valid, in order to facilitate the formation of valid arguments in language.

Here are some common valid argument forms:

Some of these argument forms, as well as some simpler ones, serve as the rules of inference by which logic can be conducted.

By contrast, invalid argument forms are arguments that do not guarantee true conclusions, regardless of whether or not their premises are true. An instance of an invalid argument form will produce a formal logical fallacy.
