History does not repeat itself except with variations, and it is idle to look for exact parallels, but we can trace a resemblance between the conditions of his time and those of to-day. Once again the crust of civilization has worn thin, and beneath can be heard the muttering of primeval fires. Once again many accepted principles of government have been overthrown, and the world has become a laboratory where immature and feverish minds experiment with unknown forces. Once again problems cannot be comfortably limited, for science has brought the nations into an uneasy bondage to each other. In the actual business of administration there is no question of today which Augustus had not to face and answer.
