In philosophy the Greeks have been the teachers of the civilized world. Two only of their great masters need be considered here. It is said that every man is born either an Aristotelian or a Platonist. This means that there are two chief types of mind which really think, and of those one is akin to the mind of Plato, the other akin to that of Aristotle. Plato is the suggestive, but inconclusive, imaginative, transcendental philosopher. Aristotle is the matter-of-fact, logical, analytical. The style is like the men. The style of Plato is rich with poetical colour, that of Aristotle is hard and thin, prose of the prose. Between them these two cover nearly all the ground of speculative thinking, and modern thought can never emancipate itself from them. For centuries in the Middle Ages the philosophy of Aristotle was almost a religion of civilized Europe, and it is the fact that even now students of morals and politics find themselves constantly returning to Aristotle. The Stagirite, as he was called because of his birth at Stagira, lived before the days of experimental science. Yet he virtually anticipated much of modern scientific results. He was nearly an evolutionist. Plato, on the other hand, has had his votaries. He, too, was a religion in Renaissance Italy. Whether we can always follow him or not, he is a stimulating influence, and he has left his mark in many places where one would hardly look for it. We should perhaps scarcely light on Wordsworth’s beautiful _Ode on the Intimations of Immortality_ as an echo of Plato. Yet all its fancy concerning “a sleep and a forgetting,” and the previous existence of the soul, is pure Plato. Whether Wordsworth was conscious of it or not, his mind had been pervaded by the Platonic influence. Nor was it much otherwise with Shelley. Of direct and appreciable bearing upon literature since his day, is the fact that Plato is our first model of the prose dialogue or imaginary conversation. He did not indeed absolutely invent this form of writing, but the comparatively crude work which preceded him is lost, and it is Plato who stands to Berkeley or Landor as their prototype and exemplar. Centuries later Lucian followed in his steps, though with a somewhat different purpose, combining, as he declared, the philosophical dialogue with the spirit of Attic comedy. Plato’s dialogues are always serious in intention, whatever humour or lightness of touch he may display; Lucian’s are but partially serious, the humour, which tends to satire, being the predominant element. A work of Plato to which the world owes much in the way of imitation is his _Ideal Commonwealth_ or _Republic_, from which are derived in succession the hints for the _Civitas Dei_ or _City of God_ of St. Augustine, the _Utopia_ of Sir Thomas More, the _New Atlantis_ of Bacon, and various minor efforts in the theoretical construction of an ideal polity. * * * * *
