The course will be based on my book: Modal Logic for Philosophers

Corrections to the book are found at:

Other accessible books on modal logic include:

B. Chellas,  Modal Logic, Cambridge, 1980.

          A well thought out book with a technical outlook.

G. Hughes & M. Cresswell,  An Introduction to Modal Logic, Methuen, 1968.

          A classic.  Somewhat dated, but comprehensive.

G. Hughes and M. Cresswell, A Companion to Modal Logic, Methuen, 1984.

          Brings their previous book up to date. 

K. Konyndyk,  Introductory Modal Logic,  Notre Dame, 1986.

          A gentle introduction with philosophical topics.

At the beginning of each class, I will assign the reading and exercises for the following classes.  Completing exercises in a timely way is crucial for success in this course.  You are expected to turn in the exercises on the day they are due.  Please get in touch with me if you have to miss a class, so that you can complete, and turn in, the work you have missed on the day you return.  There will be a midterm, two short ≥pop≤ quizzes, one before and one after the midterm, and a final.  Your grade will be determined as follows:  

Exercises: 30%,  Two pop quizzes @ 10% each: 20% Midterm Exam: 20%, Final: 30% .
