As a result the Romans developed no great scholarly or literary atmosphere, as the Greeks had done at Athens, They built up no great speculative philosophies, and framed no great theories of government. Even their literature was, in part, an imitation of the Greek, though possessing many elements of native strength and beauty. They were a people who knew how to accomplish results rather than to speculate about means and ends. Usefulness and effectiveness were with them the criteria of the worth of any idea or project. They subdued and annexed an empire, they gave law and order to a primitive world, they civilized and Romanized barbarian tribes, they built roads connecting all parts of their Empire that were the best the world had ever known, their aqueducts and bridges were wonders of engineering skill, their public buildings and monuments still excite admiration and envy, in many of the skilled trades they developed tools and processes of large future usefulness, and their agriculture was the best the world had known up to that time. They were strong where the Greeks were weak, and weak where the Greeks were strong. By reason of this difference the two peoples supplemented one another well in the work of laying the foundations upon which our modern civilization has been built. Greece created the intellectual and aesthetic ideals and the culture for our life, while Rome developed the political institutions under which ideals may be realized and culture may be enjoyed. From the Greeks and Hebrews our modern life has drawn its great inspirations and its ideals for life, while from the Romans we have derived our ideals as to government and obedience to law. One may say that the Romans as a people specialized in government, law, order, and constructive practical undertakings, and bequeathed to posterity a wonderful inheritance in governmental forms, legal codes, commercial processes, and engineering undertakings, while the Greeks left to us a philosophy, literature, art, and a world culture which the civilized world will never cease to enjoy. The Greeks were an imaginative, impulsive, and a joyous people; the Romans sedate, severe, and superior to the Greeks in persistence and moral force. The Greeks were ever young; the Romans were always grown and serious men.
