Volume VIII of the nine-volume Loeb edition of Early Greek Philosophy includes the so-called sophists Protagoras, Gorgias, Prodicus, Thrasymachus, and Hippias, along with testimonia relating to the life, views, and argumentative style of Socrates.

A major new edition of the so-called Presocratics.

The fragments and testimonia of the early Greek philosophers (often labeled the ‘Presocratics’) have always been not only a fundamental source for understanding archaic Greek culture and ancient philosophy but also a perennially fresh resource that has stimulated Western thought until the present day. This new systematic conception and presentation of the evidence differs in three ways from Hermann Diels’s groundbreaking work, as well as from later editions: it renders explicit the material’s thematic organization; it includes a selection from such related bodies of evidence as archaic poetry, classical drama, and the Hippocratic corpus; and it presents an overview of the reception of these thinkers until the end of antiquity.

Volume I contains introductory and reference materials essential for using all other parts of the edition.
Volume II presents preliminary chapters on ancient doxography, the cosmological and moral background, and includes the early Ionian thinkers Pherecydes, Thales, Anaximander, and Anaximenes.
Volume III includes the early Ionian thinkers Xenophanes and Heraclitus.
Volume IV presents Pythagoras and the Pythagorean School, including Hippasus, Philolaus, Eurytus, Archytas, Hicetas, and Ecphantus, along with chapters on doctrines not attributed by name and reception.
Volume V includes the western Greek thinkers Parmenides, Zeno, Melissus, Empedocles, Alcmaeon, and Hippo.
Volume Vi includes the later Ionian and Athenian thinkers Anaxagoras, Archelaus, and Diogenes of Apollonia, along with chapters on early Greek medicine and the Derveni Papyrus.
Volume VII includes the atomists Leucippus and Democritus.
Volume VIII includes the so-called sophists Protagoras, Gorgias, Prodicus, Thrasymachus, and Hippias, along with testimonia relating to the life, views, and argumentative style of Socrates.
Volume IX includes the so-called sophists Antiphon, Lycophron, and Xeniades, along with the Anonymous of Iamblichus, the Dissoi Logoi, a chapter on characterizations of the ‘sophists’ as a group, and an appendix on philosophy and philosophers in Greek drama.
