Proclus' Commentary on Plato's dialogue Timaeus is arguably the most important commentary on a text of Plato, offering unparalleled insights into eight centuries of Platonic interpretation. This edition offers the first new English translation of the work for nearly two centuries, building on significant recent advances in scholarship on Neoplatonic commentators. It provides an invaluable record of early interpretations of Plato's dialogue, while also presenting Proclus' own views on the meaning and significance of Platonic philosophy. The present volume, the first in the edition, deals with what may be seen as the prefatory material of the Timaeus. In it Socrates gives a summary of the political arrangements favoured in the Republic, and Critias tells the story of how news of the defeat of Atlantis by ancient Athens had been brought back to Greece from Egypt by the poet and politician Solon.

It is sometimes claimed that the Kantian Ought Implies Can principle (OIC) rules out the possibility of moral dilemmas. A certain understanding of OIC does rule out the possibility of moral dilemmas in the sense defined. However I doubt that this particular formulation of the OIC principle is one that fits well with the eudaimonist framework common to ancient Greek moral philosophy. In what follows, I explore the reasons why Aristotle would not accept the OIC principle in the form in which it rules out the possibility of moral dilemmas.
