This translation and commentary is based on the Critical Text and Indices of Proclus: Commentary on the First Alcibiades of Plato, Amsterdam 1954, by L. G. Westerink. Index II has been of great help in the translation, and the commentary is much indebted to the critical apparatus. Dr. Westerink has also been kind enough to forward his views on the relatively few problems which the Greek text has presented. A further debt is owed to the review of Dr. Westerink's text by Prof. E. R. Dodds in...

In the present volume Proclus describes the 'creation' of the soul that animates the entire universe. This is not a literal creation, for Proclus argues that Plato means only to convey the eternal dependence of the World Soul upon higher causes. In his exegesis of Plato's text, Proclus addresses a range of issues in Pythagorean harmonic theory, as well as questions about the way in which the World Soul knows both forms and the visible reality that comprises its body. This part of Proclus' ...

In his role for the next 50 years, the unmarried Proclus worked hard, combining effectively the roles of administrator, teacher and writer. Astronomy, ethics, mathematics, physics, theology - Proclus tackled all of those topics that together fel...

Parmenides Plato - This Plato is an English translation of one of the more challenging and enigmatic of Plato's dialogues between Socrates and Parmenides and Zeno of Elea, that begins with Zeno defending his treatise of Parmenidean monism against those partisans of plurality. Focus Philosophical Library translations are close to and are non-interpretative of the original text, with the notes and a glossary intending to provide the reader with some sense of the terms and the concepts as the...

Euthydemus (Euthydemos), written 380 BCE, is dialogue by Plato which satirizes the logical fallacies of the Sophists.

As in many of the dialogues, the two Sophists whom Socrates argues against, Euthydemus and Dio...
