The study of Plato's style as a writer has hardly kept pace with the study of his thought as a philosopher. Obviously he stands apart as the one original thinker in classical antiquity who also gives expression to his thought in a finished literary prose; and obviously his prose is worth studying for its own sake. What I would here suggest is that the close and continual relationship between the style and the content of his work may serve, in various aspects, to elucidate his argument; and, further, that at certain points his style itself has a direct connexion with his philosophic thought.
