Unrivaled for its clarity and comprehensiveness, Hurley's A CONCISE INTRODUCTION TO LOGIC is the No. 1 introductory logic textbook on the market. Featuring a "logic is empowering" theme, the 14th edition continues to build upon the tradition of a lucid, focused and accessible presentation of logic -- both formal and informal. 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 methodically build skills and work up to more difficult problems. The highly robust online platform WebAssign offers an expanded array of technology supplements, including a gradable interactive version of many of the book's exercises, online homework solutions, multimedia tutorials, question-level help videos and the complete text in an eBook format.
