"Even this, O Rome, must one day be thy fate!" wept Scipio over the ruins of Carthage, and Macaulay's picture of the New Zealander musing upon the broken arch of London Bridge appeals to the imagination of even those who see cities rising in the wilderness and help to lay the foundations of new empire. And so, when we erect a public building we make a hollow in the largest corner stone and carefully seal within it some mementos of our day, looking forward to the time when our works shall be ruins and ourselves forgot.
Nor whether this alternate rise and fall of civilization, this retrogression that always follows progression, be, or be not, the rhythmic movement of an ascending line (and I think, though I will not open the question, that it would be much more difficult to prove the affirmative than is generally supposed) makes no difference; for the current theory is in either case disproved.
