Much has been written about the interpretation of Plato in the last thirty years. Once interpreted as a revolutionary of the left, and a prophet of Socialism, he has lately been interpreted as a revolutionary of the Right and a forerunner of Fascism. In this book Plato appears as himself âe" a revolutionary indeed, and even an authoritarian, but a revolutionary of the pure idea of the Good, and an authoritarian of the pure reason, unattached either to the Right or the Left.
