In this 13th edition, Patrick Hurley and new co-author Lori Watson continue to build upon the tradition of a lucid, focused, and accessible presentation of logic, both formal and informal. The book's extensive, carefully sequenced exercises guide students toward greater proficiency with the skills they are learning. The range and volume of exercises allow self-pacing, enabling students who have greater difficulty to build skills slowly and methodically, and work up to more difficult problems.
