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.
