In opposition to this view, there are many languid thinkers who lapse into a forlorn belief that if this or that man had never lived, or if this or that other man had not ceased to live, the country might have gone on in peace and prosperity, until its felicity merged in the glories of the millennium.  If Mr. Calhoun had never proclaimed his heresies; if Mr. Garrison had never published his paper; if Mr. Phillips, the Cassandra in masculine shape of our long prosperous Ilium, had never uttered his melodious prophecies; if the silver tones of Mr. Clay had still sounded in the senate-chamber to smooth the billows of contention; if the Olympian brow of Daniel Webster had been lifted from the dust to fix its awful frown on the darkening scowl of rebellion,—­we might have been spared this dread season of convulsion.  All this is but simple Martha’s faith, without the reason she could have given:  “If Thou hadst been here, my brother had not died.”

They little know the tidal movements of national thought and feeling, who believe that they depend for existence on a few swimmers who ride their waves.  It is not Leviathan that leads the ocean from continent to continent, but the ocean which bears his mighty bulk as it wafts its own bubbles.  If this is true of all the narrower manifestations of human progress, how much more must it be true of those broad movements in the intellectual and spiritual domain which interest all mankind?  But in the more limited ranges referred to, no fact is more familiar than that there is a simultaneous impulse acting on many individual minds at once, so that genius comes in clusters, and shines rarely as a single star.  You may trace a common motive and force in the pyramid-builders of the earliest recorded antiquity, in the evolution of Greek architecture, and in the sudden springing up of those wondrous cathedrals of the twelfth and following centuries, growing out of the soil with stem and bud and blossom, like flowers of stone whose seeds might well have been the flaming aerolites cast over the battlements of heaven.  You may see the same law showing itself in the brief periods of glory which make the names of Pericles and Augustus illustrious with reflected splendors; in the painters, the sculptors, the scholars of “Leo’s golden days”; in the authors of the Elizabethan time; in the poets of the first part of this century following that dreary period, suffering alike from the silence of Cowper and the song of Hayley.  You may accept the fact as natural, that Zwingli and Luther, without knowing each other, preached the same reformed gospel; that Newton, and Hooke, and Halley, and Wren arrived independently of each other at the great law of the diminution of gravity with the square of the distance; that Leverrier and Adams felt their hands meeting, as it were, as they stretched them into the outer darkness beyond the orbit of Uranus, in search of the dim, unseen Planet; that Fulton and Bell, that Wheatstone and Morse, that
