To a great extent we may find the key to the Greek character in her favourite proverb, “No excess,” in which are expressed her favourite virtues of _Aidōs_ and _Sophrosune_, reverence and self-restraint. “Know thyself” was the motto inscribed over her principal shrine. Know and rely upon thine own powers, know and regard thine own limitations. It was such a maxim as this which enabled the Greeks to reach their goal of perfection even in the sphere of art, where perfection is proverbially impossible. They were bold in prospecting and experimenting, until they found what they deemed to be the right way, and when they had found it they followed it through to its conclusion. Eccentricity they hated like poison. Though they were such great originators, they cared nothing for the modern fetish of originality. In politics also they looked for a definite goal and travelled courageously along to find it. Herein they met with disastrous failures which are full of teaching for us. But they reached, it may be said, the utmost possibility of the city-state. The city-state was, as we have seen, probably evolved by natural survival from the physical conditions of the country. Being established, it entailed certain definite consequences. It involved a much closer bond of social union than any modern [Illustration: PLATE III. THE VALE OF TEMPE _English Photo Co., Athens_] territorial state. Its citizens felt the unity and exclusiveness of a club or school. A much larger share of public rights and duties naturally fell upon them. They looked upon their city as a company of unlimited liability in which each individual citizen was a shareholder. They expected their city to feed and amuse them. They expected to divide the plunder when she made conquests, as they were certain to share the consequences if she was defeated. Every full citizen of proper age was naturally bound to fight personally in the ranks, and from that duty his rights as a citizen followed logically. He must naturally be consulted about peace and war, and must have a voice in foreign policy. Also, if he was to be a competent soldier he must undergo proper education and training for it. There will be little privacy inside the walls of a city-state; the arts and crafts will be under public patronage. Inequalities will become hatefully apparent. But for us, an imperial people, who have inherited a vast and scattered dominion which somehow or other has got to be managed and governed, the chief interest will centre in the question of how these city-states acquired and administered their empires. Above all it is to Athens and perhaps Rome alone that we can look for historical answers to the great riddle for which we cannot yet boast of having discovered a solution--whether democracy can govern an empire.
