The latest times then are in truth a return to the earliest times, with this difference, that nations have taken the place of cities. Two of the masters of history in later times have pointed out the close analogy between the mutual relations of the cities of old Greece and those of the nations of modern Europe. The lesson has been taught us in its fulness alike by Arnold and by Grote. It hardly fell within the scope of either master to point out how truly the likeness is a cycle, how the later state of things is a return to the earlier, after the existence for many ages of a state of things wholly unlike either. They were hardly called on to dwell upon the causes which have brought about this return to an earlier state of things, or on the causes which made that return, as every return to an earlier state of things must be, a return only partial, a return largely modified by the events which have taken place in the meanwhile. It was enough for them to point the analogy. And the analogy is answer enough to those shallowest of the shallow who go about winning cheers from half-taught audiences by declaiming on the uselessness of studying the institutions of “petty states” and by asking what can be gained by knowing about battles fought two thousand years ago. The substitution of the nation for the city is, from one side, part of the process which we may, for our purposes, call the physical growth of the world. The world in which we live is in physical extent vastly bigger than the first civilized world of old Greece, vastly bigger than the far wider Mediterranean world of Rome. What the Ægæan and its borderlands once were, what the Mediterranean and its borderlands once were, Ocean and his borderlands, his borderlands spread over so many continents and islands, are now. No one ought to be more ready than students of political history to welcome every modern scientific invention. The discoveries which have gone so far to annihilate distance ought to call up our deepest thankfulness. But we are perhaps thankful for them on other grounds than those for which they are prized by their own inventors; we are certainly thankful for them on other grounds from those for which they are prized by those who go about bragging about the worthlessness even of the knowledge of times when those inventions were unknown. The steamer, the railway, the telegraph, are wholesome and necessary institutions; they are wholesome and necessary in order to hinder man’s intellectual and political life from being crushed by mere physical extension. They allow the England of our day to come nearer to the Athens of Periklês than the England of a hundred years back, of fifty years back. They allow the United States of America, spread over a world wider than any age of Roman empire, to abide as a Confederation free and united, the true fellow of the old Achaia shut up within the bounds of Peloponnêsos. They are needful in an age when nations have taken the place of cities, that
