For, be assured, that all the best things and treasures of this world are not to be produced by each generation for itself; but we are all intended, not to carve our work in snow that will melt, but each and all of us to be continually rolling a great white gathering snowball, higher and higher--larger and larger--along the Alps of human power. Thus the science of nations is to be accumulative from father to son: each learning a little more and a little more; each receiving all that was known, and adding its own gain: the history and poetry of nations are to be accumulative; each generation treasuring the history and the songs of its ancestors, adding its own history and its own songs: and the art of nations is to be accumulative, just as science and history are; the work of living men not superseding, but building itself upon the work of the past. Nearly every great and intellectual race of the world has produced, at every period of its career, an art with some peculiar and precious character about it, wholly unattainable by any other race, and at any other time; and the intention of Providence concerning that art, is evidently that it should all grow together into one mighty temple; the rough stones and the smooth all finding their place, and rising, day by day, in richer and higher pinnacles to heaven. Now, just fancy what a position the world, considered as one great workroom--one great factory in the form of a globe--would have been in by this time, if it had in the least understood this duty, or been capable of it. Fancy what we should have had around us now, if, instead of quarrelling and fighting over their work, the nations had aided each other in their work, or if even in their conquests, instead of effacing the memorials of those they succeeded and subdued, they had guarded the spoils of their victories. Fancy what Europe would be now, if the delicate statues and temples of the Greeks,--if the broad roads and massy walls of the Romans,--if the noble and pathetic architecture of the middle ages, had not been ground to dust by mere human rage. You talk of the scythe of Time, and the tooth of Time: I tell you, Time is scytheless and toothless; it is we who gnaw like the worm--we who smite like the scythe. It is ourselves who abolish--ourselves who consume: we are the mildew, and the flame, and the soul of man is to its own work as the moth, that frets when it cannot fly, and as the hidden flame that blasts where it cannot illumine. All these lost treasures of human intellect have been wholly destroyed by human industry of destruction; the marble would have stood its two thousand years as well in the polished statue as in the Parian cliff; but we men have ground it to powder, and mixed it with our own ashes. The walls and the ways would have stood--it is we who have left not one stone upon another, and restored its pathlessness to the desert; the great cathedrals of old religion would have stood--it
