For the lack of forty-nine drachmas Socrates was unable to attend the costly epideixis of Prodicus from which he would have learnt the truth about correct use of words. From Prodicus' ὥραι Socrates could also have learnt the concepts and characteristic words associated with arete and kakia: these compete in that work for the allegiance of Heracles, parading their respective characteristics. Thanks to Professor Arthur Adkins we have had for the past decade a book which not only confronts arete and (...) kakia, but also analyses the meaning and usage of many Greek words for the evaluation of action from Homer to Aristotle. The importance of this book is generally acknowledged but it has not received the detailed discussion it deserves. Professor Adkins finds the social structure of ancient Greece inimical to the development of an adequate concept of moral responsibility. He shows, in a most interesting manner, how Greek values changed as the needs of society changed. (shrink)
