**Course description:** An argument is a list of sentences where the last is the conclusion and the rest are premises. What makes some arguments good and others not? One answer is validity. A valid argument is one where the premises entail the conclusion. That is, if the premises were true, then the conclusion would have to be as well. Deductive logic is the formal study of validity, and the majority of this class will focus on it. Inductive logic on the other hand is concerned with probabilistic support. That is, sometimes premises do not guarantee a conclusion, but they do make it more likely to be true. Our goal here is understanding Bayes’ rule.

**Text:** Language, Proof, and Logic by John Barwise and John Etchemendy

DO NOT BUY USED, the code to submit assignments wont work!

**Objectives:** – Understand what it means for an argument to be valid. – Build techniques for proving arguments valid or invalid. – Understand what it means for an argument to be strong. – Develop a familiarity with probability and Bayes’ theorem.
