Lucius Annaeus Seneca, Six Tragedies, translated with an introduction by Emily Wilson (Oxford & New York: Oxford World's Classics/Oxford U. Press, 2010).
Emily R. Wilson, The Death of Socrates (Cambridge, Massachusetts: Harvard U. Press, 2007) ("Alternatively, Socrates believed that human beings can count as 'wise' in a third, limited sense: if they understand their own ignorance in comparison with divine enlightenment. Socrates, in this interpretation, viewed himself as the only person in the world who came anywhere near to divine wisdom." "Perhaps, as Robert Nozick has argued, Socrates genuinely did not know how to define many evaluative terms, such as courage, holiness, or justice. But he knew more than most people, because he had at least rejected some common false beliefs about these concepts, such as the idea that holiness simply means making the guilty suffer, or doing the things the gods like. He knew that most people are wrong or misguided in thinking they know anything about their own systems of belief and value." Id. at 37.).
Emily R. Wilson, Mocked with Death: Tragic Overliving From Sophocles to Milton (Baltimore & London: The Johns Hopkins University Press, 2004) ("This book argues that there is a central thread in the tragic tradition that is concerned not with dying too early but with living too long, or 'overliving'." Id. at 1. "People have always wondered whether life is worth living, and tragic narratives have always included a suspicion that life goes on too long, and that never to be born is best." Id. at 23.).
