Lesson 5 – Deductive Argument

In this lesson, we will explore deductive arguments, which are structured in a way that ensures the conclusion must be true if the premises are true and the conclusion contains nothing that is not in the premises. The focus is on the argument’s structure, not the content. Using examples, we will distinguish between valid and invalid arguments and explain how the validity of an argument depends on the truth of its premises. We will also learn that a sound argument is one that is both valid and true. By the end of this lesson, you will have a better understanding of the structure of deductive arguments and how to evaluate their validity.
