Plato's Theaetetus and Sophist are two of his most important dialogues, and are widely read and discussed by philosophers for what they reveal about his epistemology and particularly his accounts of belief and knowledge. Although they form part of a single Platonic project, these dialogues are not usually presented as a pair, as they are in Christopher Rowe's new and lively translation. Offering a high standard of accuracy and readability, the translation reveals the continuity between these dialogues and others in the Platonic corpus, especially the Republic. The supporting introduction and notes help the reader to follow the arguments as they develop, explaining their structure, context and interpretation. This new edition challenges current scholarly approaches to Plato's work and will pave the way for fresh interpretations both of Theaetetus and Sophist and of Plato's writings in general.
