It is objected that the art of printing contributes to the preservation of a civilization by the facility with which it multiplies and diffuses the masterpieces of the human mind, so that, even in times of intellectual sterility, when they can no longer be emulated, they still form the standard of taste, and by their clear and steady light prevent the possibility of utter darkness. But it should be remembered that to delve in the hoarded treasures of thought, and to appropriate them for purposes of mental improvement, presupposes the possession of that greatest of earthly goods--an enlightened mind. And in epochs of intellectual degeneracy, few care about those monuments of lost virtues and powers; they are left undisturbed on their dusty shelves in libraries whose silence is but seldom broken by the tread of the anxious, painstaking student. The longevity which Guttenberg's invention assures to the productions of genius is much exaggerated. There are a few works that enjoy the honor of being reproduced occasionally; with this exception, books die now precisely as formerly did the manuscripts. Works of science, especially, disappear with singular rapidity from the realms of literature. A few hundred copies are struck off at first, and they are seldom, and, after a while, never heard of more. With considerable trouble you can find them in some large collection. Look what has become of the thousands of excellent works that have appeared since the first printed page came from the press. The greater portion are forgotten. Many that are still spoken of, are never read; the titles even of others, that were carefully sought after fifty years ago, are gradually disappearing from every memory. So long as a civilization is vigorous and flourishing, this disappearance of old books is but a slight misfortune. They are superseded; their valuable portions are embodied in new ones; the seed exists no longer, but the fruit is developing. In times of intellectual degeneracy it is otherwise. The weakened powers cannot grapple with the solid thought of more vigorous eras; it is split up into more convenient fragments--rendered more portable, as it were; the strong beverage that once was the pabulum of minds as strong, must be diluted to suit the present taste; and innumerable dilutions, each weaker than the other, immediately claim public favor; the task of learning must be lightened in proportion to the decreasing capacity for acquiring; everything becomes superficial; what costs the least effort gains the greatest esteem; play upon words is accounted wit; shallowness, learning; the surface is preferred to the depth. Thus it has ever been in periods of decay; thus it will be with us when we have once reached that point whence every movement is retrogressive. Who knows but we are near it already?--and the art of printing will not save us from it.
