Widely praised for its accessibility and its concentration on the metaphysical issues that are central to the history of Greek philosophy, this volume offers a valuable introduction to the works of the Presocratics, Plato and Aristotle. For the Second Edition, Professor Allen has provided such new selections as Plato's Crito, Socrates' speech in the Symposium, and the first five chapters of Aristotle's Categories, as well as his own fresh translations of Plato's Euthyphro, Apology, and Permenides. He has also fully revised and updated his general introduction, selective bibliography, and lists of suggested readings.
