In this fascinating introduction, David Bostock presents a fresh perspective on one of the great classics of moral philosophy: Aristotle's Nicomachaen Ethics. He argues that it is, and deserves to be, Aristotle's most widely studied work, for much of what it has to say is still important for today's debate on the problems of ethics. Here, Bostock guides the reader through explanations and evaluations of all the main themes of the work, exploring questions of interpretation and the differing views of a range of commentators. He also emphasizes the philosophical merits and faults of the doctrines that emerge, critically discussing them in a simple, straightforward way. Each chapter concludes with suggestions for further reading on the themes discussed within the chapter, and the book finishes with an evaluation of the Ethics as a whole. The ideal companion for study of Aristotle's great insights, this book helps the reader to engage with his ideas and arguments as living philosophy.
