Unsurpassed for its clarity, conciseness, and comprehensiveness, Hurley's market-leading A CONCISE INTRODUCTION TO LOGIC has established itself as the standard for introductory logic classes. Hailed in the first eight editions for an unwavering commitment to lucid, focused, reader-friendly presentations of logic's basic topics, the latest edition also continues to expand upon Hurley's tradition of technological excellence with the introduction of vMentor and iLrn Logic. These two technologies help you manage the workload of teaching logic by providing your students with a live, online logic tutoring service and you with an online system that automates homework and test grading. In addition, Hurley's outstanding LEARNING LOGIC-an interactive, audio-visual recasting of the entire text-remains a free supplement with each copy of the text. Rounded out with a Book Companion Website that features student quizzing and interactive tutorials on Venn diagrams and truth tables, Hurley's A CONCISE INTRODUCTION TO LOGIC, Ninth Edition is not only the most logically sound choice that a professor could make for his or her logic course, but the most technologically" sound choice as well.
