Course Description

Whether intentional or not, logical fallacies are mistakes in reasoning. They’re specific problems in arguments that lead to incorrect conclusions. There are many logical fallacies, but some are more common and relevant. These include fallacies of relevance, fallacies of unacceptable premises, and formal fallacies. These are often shortcuts we find ourselves tempted to take. But it’s not recommended that you use fallacies in your arguments. Even the best reasoners make mistakes and have occasional slip-ups. Logical reasoning isn’t easy, and it requires practice. What are the different types of fallacies? How can you avoid them in your arguments?

In this course, Logical Fallacies, you will learn about the different types of fallacies people use in their arguments. This includes informal fallacies, such as the red herring and the slippery slope. It also includes formal fallacies, including affirming the consequent and denying the antecedent. You will also learn how to avoid logical fallacies by considering all of the evidence and putting aside your personal preferences. By the end of this course, you will have the skills to make better arguments.
