Introduction to Logic is clear and concise, uses interesting examples, and has innovative, easy-to-use proof methods. It covers a wide range of topics, including syllogisms; definitions and fallacies; inductive reasoning; propositional and quantificational logic; modal, deontic, and belief logic; and metalogic, history of logic, deviant logic, and philosophy of logic. Different parts can be used in a range of logic courses. Updates to the Third Edition include fuller coverage of traditional Copi proofs, better explanations of truth trees, improved explanations throughout, and updated and improved LogiCola software (still free from http://www.harryhiker.com/lc).　

Introduction to Logic is clear and concise, uses interesting examples (many philosophical in nature), and has easy-to-use proof methods. Its key features, retained in this Third Edition, include:

• simpler ways to test arguments, including an innovative proof method and the star test for syllogisms;
• a wide scope of materials, suiting it for introductory or intermediate courses;
• engaging examples, from philosophy and everyday life;
• useful for self-study and preparation for standardized tests, like the LSAT;
• a reasonable price (a third the cost of some competitors); and
• exercises that correspond to the free LogiCola instructional program.

• improves explanations, especially on areas that students find difficult;
• has a fuller explanation of traditional Copi proofs and of truth trees; and
• updates the companion LogiCola software, which now is touch friendly (for use on Windows tablets and touch monitors), installs more easily on Windows and Macintosh, and adds exercises on Copi proofs and on truth trees. You can still install LogiCola for free (from http://www.harryhiker.com/lc or http://www.routledge.com/cw/gensler).
