"This volume is an impressive tour de force. It is state-of-the-art Aristotle: it employs the most recent philological, philosophical, and logical advances which since the 1970's at least have rendered previous translations and commentaries obsolete. The translation is the first to take account of the recent epistemically orientated natural-deduction approach, which restores Aristotle's reputation as a consummate logician and reveals much more of Aristotle's method than previous approaches. Every page of Robin Smith's commentary shows extensive learning, taste, imagination, and skill. . . . An important and lasting contribution, not only to Aristotle scholarship and to the history of logic, but also to the history of philosophy itself." --John Corcoran, SUNY Buffalo
