A Logical Fallacies Discussion List is available at the main site.

The point of an argument is to give reasons in support of some conclusion. An argument commits a fallacy when the reasons offered do not support the conclusion.

These pages describe the known logical fallacies. To browse, either go to the table of contents, follow the 'next' and 'previous' icons or try the pop-up navigation window.

See How To Use This Guide.

If you can think of more fallacies that you'd really like to see, please send me a note. For more information: please consult the references and resource pages. For educators: the entire website is available for easy download. Please see the bottom of the Table of Contents page. And as always, I hope you'll find the time to browse my home page. Thanks for the support!

In the long run, this site will become a complete discussion of logic. In my view, the reasons why the fallacies are, in fact, fallacies should be given. As a prelude to this, please take a look at The Categorical Converter (note that it needs to be supported with more informative pages, however, it may be of interest to people who already understand categorical inferences).
