TMU #7: Logical Fallacies

Counterfeit arguments are fallacious, and you are about to see them everywhere

Logical fallacies often sound like good arguments, but they are fallacious and untrue. By the end of today’s lesson, you’ll be able to recognize logical fallacies everywhere.

In this week’s lesson, you will learn…

  • A review of the logical syllogism, the structure of the building blocks of persuasion.
  • Review of the major, minor premises and the conclusion, and the questions we ask to understand them.
  • Differences between formal and informal fallacies.
  • How to watch for fallacies in the news, when something doesn’t make sense.
  • Geisler’s and Brook’s opinion of what “fallacies” are.
  • Nine (9) popular fallacies broken into three (3) categories: Attack Fallacies, Appeal Fallacies and Diversion Fallacies.
  • Examples in the daily news (specifically from WSJ and the Colorado Springs Gazette) of fallacies.

    Catching up! Is the appeal to popularity also called the bandwagon fallacy? I seem to remember that term.

    And, when I think of logical fallacies, I think of some of Peter Kreeft’s books, which touch on them, too. Have you read THE UNABORTED SOCRATES? It’s a rather old book now, but very interesting, and the point that logic in and of itself will not convince is brought out, but it’s interesting to read the arguments anyway.

    • Yes, Bandwagon is a term used to Appeal to Popularity. Get on board or you’re going to be walking!

      I have not heard of Peter Kreeft, but I’ll look him up. Thanks Mary!

        Two things. One: I can lend you some of his books if you like. He is (or was) a professor of philosophy in Boston. Two: When I received your reply just now, I couldn’t answer directly because the internet gremlin said I didn’t have the right – something technological. This has happened before. Actually, the gremlin said I don’t have Google Chrome, but that’s what I’m using. If I get to this page by another route, then I can write. Just letting you know so you can add one more job to your to-do list.

        • Those gremlins! I understand, and will look into it.

          Are you going to the Centenniel Tournament next month in Colorado Springs? I’d love to pick up the book then if you bring it with you.

            I’m hoping to be asked to judge! I have a couple of Peter Kreeft’s books, and I’ll put them aside for you. (I had to get to this page by a devious route to get away from the gremlins.)
