About the Course

We encounter fallacies almost everywhere we look. Politicians, salespeople, and children commonly use fallacies in order to get you to think whatever they want you to think. It’s important to learn to recognize fallacies so that you can avoid being fooled by them. It’s also important to learn about fallacies so that you avoid making fallacious arguments yourself. This course will show you how to identify and avoid many of the fallacies that lead people astray. In this course, you will learn about fallacies. Fallacies are arguments that suffer from one or more common but avoidable defects: equivocation, circularity, vagueness, etc. It’s important to learn about fallacies so that you can recognize them when you see them, and not be fooled by them. It’s also important to learn about fallacies so that you avoid making fallacious arguments yourself. Suggested Readings Students who want more detailed explanations or additional exercises or who want to explore these topics in more depth should consult Understanding Arguments: An Introduction to Informal Logic, Ninth Edition, Concise, Chapters 13-17, by Walter Sinnott-Armstrong and Robert Fogelin. Course Format Each week will be divided into multiple video segments that can be viewed separately or in groups. There will be short ungraded quizzes after each segment (to check comprehension) and a longer graded quiz at the end of the course....

This course helped me better understand logical fallacies and improved my ability to analyze arguments more critically and think more clearly before accepting conclusions.

lack of examples for bad arguments of particular type after saying we're going to look at some examples, as if parts of the course are missing. Quiz on material not covered.
