Abstract
If philosophy weaves its speeches by distinguishing the basic elements of human experience and then collecting them into significant wholes, Dorter's wise book exemplifies the essential movement of philosophical thought. This polished, scholarly, insightful study explores the unity, not only of the four dialogues mentioned in its title, but in an important sense of the Platonic corpus as a whole. Dorter's fresh defense of the unorthodox view that in the so-called later dialogues Plato "retained the theory [of forms] in all its essentials" constitutes an important contribution to Platonic studies. This is not all. The Plato that emerges from Dorter's study is no longer a primitive practitioner of modern techniques of analysis, but a thinker who challenges all of the major alternatives on the contemporary philosophical scene. In reacquainting us with the distinctive shape of Plato's metaphysics, Dorter opens up a possibility that is scarcely acknowledged in current philosophical discourse, namely, that "ontological thinking may lead to moral or spiritual transformation". His book will be of interest to anyone willing to entertain the idea that philosophy can improve the soul.
