Eryxias

The two dialogues which are translated in the second appendix are not mentioned by Aristotle, or by any early authority, and have no claim to be ascribed to Plato. They are examples of Platonic dialogues to be assigned probably to the second or third generation after Plato, when his writings were well known at Athens and Alexandria. They exhibit considerable originality, and are remarkable for containing several thoughts of the sort which we suppose to be modern rather than ancient, and which therefore have a peculiar interest for us. The Second Alcibiades shows that the difficulties about prayer which have perplexed Christian theologians were not unknown among the followers of Plato. The Eryxias was doubted by the ancients themselves: yet it may claim the distinction of being, among all Greek or Roman writings, the one which anticipates in the most striking manner the modern science of political economy and gives an abstract form to some of its principal doctrines.
