"In virtue of its text alone, this book represents a major advance; and the essays, which range far beyond the text . . ., are considerable works of philosophical interpretation in their own right. Anyone interested in Aristotle will want to own this book: it will be conned, discussed, and valued, for years to come."---Jonathan Barnes, Greece and Rome"An achievement that deserves warm thanks and congratulation."---John Ackrill, Philosophical Review"Martha C. Nussbaum, Recipient of the 2012 Prince of Asturias Award for Social Sciences"
