About the Author

Patrick Hurley was born in Spokane, Washington in 1942. He received his bachelor's degree in mathematics (with a Physics minor) from Gonzaga University in 1964 and his Ph.D. in philosophy of science with an emphasis in history of philosophy from Saint Louis University in 1973. In 1972 he began teaching at the University of San Diego, where his courses have included logic, philosophy of science, metaphysics, process philosophy, and legal ethics. In 1987 he received his J.D. from the University of San Diego and he is currently a member of the California Bar Association. He retired from teaching in 2008, but continues his research and writing. His interests include music, art, opera, environmental issues, fishing, and skiing.

Reviews

"Hurley has. . . always been straight to the point and clear on definition. Now, it is much more expanded with modern and creative examples that ease up on the tenseness inherent in learning logic."

"Hurley's text provides a methodical introduction to the strategies and techniques usually covered in an introductory logic course, including both formal and informal topics. Numerous exercises provide plenty of opportunity for students to practice the skills they have learned."

"It is the clearest text, with the best technology available."

"This is the 'gold standard' of introductory logic texts."

"What I like perhaps most about Hurley's text is the organization of the material. His book introduces the material in step-by-step way, building off of what was just learned the section before and adding just enough information to each section to simplify the whole process of learning logic."
