This second set of papers by John Rist is concerned with attempts by (mostly pagan) thinkers in Greco-Roman antiquity to understand the nature of morality against a background of wide-ranging debate about the relationship between soul and body and the necessity for a correct psychology and physiology if the 'good life for man' is to be revealed. Three papers are on Plato, whose elaborate mix of ethics, psychology and metaphysics sets the stage for most of the debate; one is on Aristotle, five are on the Stoics and five on Plotinus. A further study deals with the general problem of the relationship between ethics, cosmology and biology, and the series concludes with the crisis among both pagans and Christians in late antiquity over whether man is naturally good enough to correct his own moral weakness. The set of difficulties recognised by Plato has now found a disturbing conclusion.
