Four related themes in Greek thought are examined in this book: (1) personality and self, (2) ethics and values (3) individuals and communities, and (4) the idea of nature as a moral norm. Although the focus is on Greek philosophy (the Presocratics, Plato, Aristotle, and the Hellenistic period), links between philosophy and literature or the wider culture are also explored. The book combines a survey of recent scholarship on these topics with the author's own interpretations. It can be used by students or teachers of classical studies or philosophy as an introduction to key themes and issues in Greek ethics or psychology. One aspect of the subject given special emphasis is the relationship between ancient and modern ideas on the issues treated here. The book closes with a selective bibliography on modern work on Greek philosophy.
