David Bostock presents a fresh critical introduction to one of the great classics of moral philosophy. Aristotle's Nicomachaen Ethics is and deserves to be his most widely studied work, for much of what it has to say is still important for today's debate on the problems of ethics. In this new book, David Bostock guides the reader through explanations and evaluations of all the main themes of Aristotle's work, paying due attention to questions of interpretation, and the differing views of a range of commentators. The emphasis is on the philosophical merits and demerits of the doctrines that emerge and these are critically discussed in simple and straightforward terminology. Each chapter concludes with suggestions for further reading on the themes and ideas discussed within the chapter, and the book finishes with an evaluation of the Ethics as a whole. Bostock provides the ideal companion to study of this great work, helping the reader to engage with its ideas and arguments as living philosophy.
