This is a course in first-order classical logic and its metatheory. It presupposes at least one previous course in formal logic, such as Phil 155 Introduction to Mathematical Logic or Phil 456 Advanced Symbolic Logic. It might be possible for students with unusually mature mathematical skills to take this course without a previous course in logic (and even such students are likely to find chapters 9 and 10 of the textbook especially challenging) but most students will experience much less trauma if they do things in the right order.

We will work our way through the “intermediate logic” track of the 5th edition of Boolos, Burgess, and Jeffrey’s classic textbook Logic and Computability. You may buy this at the bookstore, or order it online from the usual vendors.

Topics and Readings

The assigned readings for the course are listed in the syllabus below. “L&C” stands for Logic and Computability (our textbook.) If a section of the textbook is marked with a “star” (*) for “optional”, it is not part of the required reading (unless it explicitly says otherwise below.)
