In Plato on the Unity of the Virtues, Rod Jenks argues that while Plato makes several attempts to show how virtue is one, he deliberately fails to secure this because he thinks the way in which the virtues are both one and many is finally ineffable.

Investigates Plato's account of the tripartite soul, looking at how the theory evolved over the Republic, Phaedrus and Timaeus.

In this authoritative discussion of the philosophy of Plato and Aristotle, A. W. Price considers four related areas: eudaimonia, or living and acting well, as the ultimate end of action; virtues of character in relation to the emotions, and to one another; practical reasoning, especially from an end to ways or means; and acrasia, or action that is contrary to the agent's own judgement of what is best. The focal concept is that of eudaimonia, which both Plato and Aristotle view as an abstract goal that is valuable enough to motivate action. Virtue has a double role to play in making its achievement possible, both in proposing subordinate ends apt to the context, and in protecting the agent against temptations to discard them too easily. For both purposes, Price suggests that virtues need to form a unity--but one that can be conceived in various ways. Among the tasks of deliberation is to work out how, and whether, to pursue some putative end in context. Aristotle returns to early Plato in finding it problematic that one should consciously sacrifice acting well to some incidental attraction; Plato later finds this possible by postulating schism within the soul. Price maintains that it is their emphasis upon the centrality of action within human life that makes the reflections of these ancient philosophers perennially relevant.

Stauffer demonstrates the complex unity of Plato's Gorgias through a careful analysis of the dialogue's three main sections. This includes Socrates' famous argumentative duel with Callicles, a passionate critic of justice and philosophy, showing how the seemingly disparate themes of rhetoric, justice and the philosophic life are woven together into a coherent whole. His interpretation of the Gorgias sheds new light on Plato's thought, showing that Plato and Socrates had a more favourable view of rhetoric than is usually supposed. Stauffer also challenges common assumptions concerning the character and purpose of some of Socrates' most famous claims about justice. Written as a close study of the Gorgias, Stauffer also treats broad questions concerning Plato's moral and political psychology and uncovers the view of the relationship between philosophy and politics that guided Plato as he wrote his dialogues.

This is the first collected volume dedicated to Olympiodorus of Alexandria, the last pagan Platonic philosopher at the end of antiquity.
