This book explores Plato's views on what an 'art of argument' should look like, investigating the relationship between psychology and rhetoric.

"The Value of Philosophy" is one of the most important chapters of Bertrand's Russell's magnum Opus, The Problems of Philosophy. As a whole, Russell focuses on problems he believes will provoke positive and constructive discussion, Russell concentrates on knowledge rather than metaphysics: If it is uncertain that external objects exist, how can we then have knowledge of them but by probability. There is no reason to doubt the existence of external objects simply because of sense data.

Plato's dialogue the Timaeus-Critias presents two connected accounts, that of the story of Atlantis and its defeat by ancient Athens and that of the creation of the cosmos by a divine craftsman. This book offers a unified reading of the dialogue. It tackles a wide range of interpretative and philosophical issues. Topics discussed include the function of the famous Atlantis story, the notion of cosmology as 'myth' and as 'likely', and the role of God in Platonic cosmology. Other areas commented upon are Plato's concepts of 'necessity' and 'teleology', the nature of the 'receptacle', the relationship between the soul and the body, the use of perception in cosmology, and the work's peculiar monologue form. The unifying theme is teleology: Plato's attempt to show the cosmos to be organised for the good. A central lesson which emerges is that the Timaeus is closer to Aristotle's physics than previously thought.

In Plato's Apology, Socrates says he spent his life examining and questioning people on how best to live, while avowing that he himself knows nothing important. Elsewhere, however, for example in Plato's Republic, Plato's Socrates presents radical and grandiose theses. In this book Sandra Peterson offers a hypothesis which explains the puzzle of Socrates' two contrasting manners. She argues that the apparently confident doctrinal Socrates is in fact conducting the first step of an examination: by eliciting his interlocutors' reactions, his apparently doctrinal lectures reveal what his interlocutors believe is the best way to live. She tests her hypothesis by close reading of passages in the Theaetetus, Republic and Phaedo. Her provocative conclusion, that there is a single Socrates whose conception and practice of philosophy remain the same throughout the dialogues, will be of interest to a wide range of readers in ancient philosophy and classics.

Acclaimed philosopher and novelist Rebecca Newberger Goldstein provides a dazzlingly original plunge into the drama of philosophy, revealing its hidden role in today's debates on religion, morality, politics, and science.

Daniel Russell examines Plato's subtle and insightful analysis of pleasure and explores its intimate connections with his discussions of value and human psychology. Russell offers a fresh perspective on how good things bear on happiness in Plato's ethics, and shows that, for Plato, pleasure cannot determine happiness because pleasure lacks a direction of its own. Plato presents wisdom as a skill of living that determines happiness by directing one's life as a whole, bringing aboutgoodness in all areas of one's life, as a skill brings about order in its materials. The 'materials' of the skill of living are, in the first instance, not things like money or health, but one's attitudes, emotions, and desires where things like money and health are concerned. Plato recognizes thatthese 'materials' of the psyche are inchoate, ethically speaking, and in need of direction from wisdom. Among them is pleasure, which Plato treats not as a sensation but as an attitude with which one ascribes value to its object. However, Plato also views pleasure, once shaped and directed by wisdom, as a crucial part of a virtuous character as a whole. Consequently, Plato rejects all forms of hedonism, which allows happiness to be determined by a part of the psyche that does not direct one'slife but is among the materials to be directed. At the same time, Plato is also able to hold both that virtue is sufficient for happiness, and that pleasure is necessary for happiness, not as an addition to one's virtue, but as a constituent of one's whole virtuous character itself. Plato thereforeoffers an illuminating role for pleasure in ethics and psychology, one to which we may be unaccustomed: pleasure emerges not as a sensation or even a mode of activity, but as an attitude - one of the ways in which we construe our world - and as such, a central part of every character.

A. G. Long presents a new account of the importance of conversation in Plato's philosophy. He provides close studies of eight dialogues, including some of Plato's most famous works, and traces the emergence of internal dialogue or self-questioning as an alternative to the Socratic conversation from which Plato starts.
