beautifully lucid and carefully reasoned ... the conventional wisdom is triumphantly refuted. Whitaker takes us through the de Interpretatione chapter by chapter, displaying it as a sequence of lessons for would-be dialecticians. He casts much new light on the overall structure and purpose of the remarks ... Before reading Whitaker, I too was in thrall to conventional wisdom; after reading Whitaker, things seemed to come into proper focus for the first time. Whitaker... uses his ingenuity to construct a reading that confronts, rather than evades, the subtleties of Aristotle's discussion, and to give, for the first time that I know of, a plausible account of them.
