The Phaedo is acknowledged to be one of Plato's masterpieces, showing him both as a philosopher and as a dramatist at the height of his powers. For its moving account of the execution of Socrates, the Phaedo ranks among the supreme literary achievements of antiquity. It is also a document crucial to the understanding of many ideas deeply ingrained in western culture, and provides one of the best introductions to Plato's thought. This new edition is eminently suitable for readers new to Plato, offering a readable translation which is accessible without the aid of a commentary and assumes no prior knowledge of the ancient Greek world or language.
