This social and political organization was a new work, a higher civilization, and it demanded a new and, in fact, a larger sphere. The centre of the civilized world now changes place, and, moving westward, establishes itself in the peninsula of Italy. By successive conquests its circumference enlarges, and finally it embraces at once the South and the East and the West. The place which Rome occupied, in the very middle of the basin of the Mediterranean Sea, seemed to foreshadow that she was destined to become the metropolis of all the civilized nations who dwelt upon its shores. Rome extended its conquests to Spain, Gaul, Britain, Illyria, Greece, Asia Minor, Egypt, Africa, and the islands of the Mediterranean--over, in fact, six hundred thousand square leagues of the most fertile country; and all but realized the dream of the world's great conquerors--a universal empire. It was defended by a regular army of five hundred thousand men, ranged in the order of the famous legions, which constituted the most effective military organization known. The government of an empire of such vast proportions and diversity of populations demanded the greatest political skill. To establish durable ties between these diverse peoples, and to combine in the same social network all the civilized nations of the world, demanded the highest legislative talent, and gave birth to the science of jurisprudence, which, next to that of theology, is the most important and useful to man. The inability of the Greek to achieve this great work is clearly evinced by the terrible Peloponnesian War and the lamentable history of the empire of Alexander and his successors. Greece represents individuality; Rome, association, unity, and, in some degree, the equality of all races of men.
