Excerpt from The Platonic Dialogues, Vol. 3: For English Readers These Dialogues differ in their aim and sub stance from those which I have already published, in that they are not negative but positive, not critical merely but constructive. Two previous Classes of these Dialogues - the Dialogues of the Socratic School, and the anti-sophist Dialogues - are employed in analysing and disproving defi nitions and opinions there propounded; and the other Class, the Dialogues connected with the Trial and Death of Socrates, contains hardly any positive doctrine except that of the Immortality of the Soul. The Dialogues now presented, on the other hand, are full of positive doctrines, ethical, political, and physical, given along with their professed proofs. The Republic contains, especially, a theory respecting the foundations of morality which, if true, supplies an answer to many of the questions discussed in the previous Classes of Dialogues. In those previous Classes, Plato was in search of ethical definitions and ethi cal truths: in the Republic, he conceives himself to have found such definitions and such truths. There he was an enquirer and a critic: here he is a theorist and a moralist. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
