Memorizing hundreds of fallacies has no power to keep anyone from deception. For several reasons, people who study logic are often more blinded by illusion than those who don’t study logic. For one, those who memorize fallacies often don’t understand the terms. They passed the test in school. They don’t understand how to apply those memorized definitions rationally. They accuse others of committing fallacies when those people haven’t committed fallacies. And they can’t see their own fallacies. They twist the rules of logic to fit their desired conclusions. They blatantly use fallacies to prove their points. They begin every bit of reasoning with bare claims. That’s how they deceive others. Mostly, they deceive themselves.
