Featuring an exceptionally clear writing style and a wealth of real-world examples and exercises, Logic, Fourth Edition, shows how logic relates to everyday life, demonstrating its applications in such areas as the workplace, media and entertainment, politics, science and technology, student life, and elsewhere. The examples and exercises were chosen to be interesting, thought-provoking, and relevant to students.

The text is enhanced by Dashboard, Oxford University Press' learning management platform, which offers a wealth of learning resources, including interactive proof-checking and truth table exercises. The fourth edition features new illustrations in Chapter 1; clearer treatments of existential import and the traditional square of opposition in Chapter 5; and a new appendix, "The LSAT and Logical Reasoning."
