Unsurpassed for its clarity and comprehensiveness, A CONCISE INTRODUCTION TO LOGIC is the 1 introductory logic textbook on the market. 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&39;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.
