An introduction to the theory of deductive reasoning. We consider deductive arguments in philosophy, in everyday life, and in mathematical proofs, and discuss what distinguishes valid inferences from fallacies. The course will cover propositional logic and first-order logic. Open to all students. Quantitative.


Logic, broadly understood, is the study of reasoning. More specifically, it is the study of reasoning well. In Logic, we are interested in the activity of presenting arguments. But what makes an argument good? What makes an argument bad? What are the hallmarks we can use to identify good and bad arguments? In Formal Logic, we study these questions from a content-free perspective. That is, we focus on the form or structure of the argument rather than its content. 

This course presupposes no background in Logic. We will cover the fundamentals of the syntax and semantics of Sentential Logic and Quantified Logic with identity. We will practice translating English sentences into sentences in formal languages, and we will learn how to use these formal languages to evaluate arguments. Along the way we will uncover some fascinating features of these formal languages. We will learn how to use tools like truth tables and natural deduction diagrams. We will also cover key concepts in logic, such as validity, logical truth, logical falsehood, consistency, soundness, and completeness.

Registrar Notes:


SFU’s Academic Integrity website http://www.sfu.ca/students/academicintegrity.html is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating. Check out the site for more information and videos that help explain the issues in plain English.

Each student is responsible for his or her conduct as it affects the university community. Academic dishonesty, in whatever form, is ultimately destructive of the values of the university. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the university. http://www.sfu.ca/policies/gazette/student/s10-01.html
