In our day, it is said despairingly, the understanding reigns triumphant: it is the age of common sense. If this be so, the wisest way would be to accept it manfully. But, after all, what is the meaning of it? Looking at the matter superficially, one would say that a striking difference between our science and that of the world's gray fathers is that there is every day less and less of the element of wonder in it. What they saw written in light upon the great arch of heaven, and, by a magnificent reach of sympathy, of which we are incapable, associated with the fall of monarchs and the fate of man, is for us only a professor, a piece of chalk, and a blackboard. The solemn and unapproachable skies we have vulgarized; we have peeped and botanized among the flowers of light, pulled off every petal, fumbled in every calyx, and reduced them to the bare stem of order and class. The stars can no longer maintain their divine reserves, but whenever there is a conjunction and congress of planets, every enterprising newspaper sends thither its special reporter with his telescope. Over those arcana of life where once a mysterious presence brooded, we behold scientific explorers skipping like so many incarnate notes of interrogation. We pry into the counsels of the great powers of nature, we keep our ears at the keyhole, and know everything that is going to happen. There is no longer any sacred inaccessibility, no longer any enchanting unexpectedness, and life turns to prose the moment there is nothing unattainable. It needs no more a voice out of the unknown proclaiming "Great Pan is dead!" We have found his tombstone, deciphered the arrow-headed inscription upon it, know his age to a day, and that he died universally regretted. Formerly science was poetry. A mythology which broods over us in our cradle, which mingles with the lullaby of the nurse, which peoples the day with the possibility of divine encounters, and night with intimation of demonic ambushes, is something quite other, as the material for thought and poetry, from one that we take down from our bookshelves, as sapless as the shelf it stood on, as remote from all present sympathy with man or nature as a town history with its genealogies of Mr. Nobody's great-grandparents. We have utilized everything. The Egyptians found a hint of the solar system in the concentric circles of the onion, and revered it as a symbol, while we respect it as a condiment in cookery, and can pass through all Weathersfield without a thought of the stars. Our world is a museum of natural history; that of our forefathers was a museum of supernatural history. And the rapidity with which the change has been going on is almost startling, when we consider that so modern and historical a personage as Queen Elizabeth was reigning at the time of the death of Dr. John Faustus, out of whose story the Teutonic imagination built up a mythus that may be set beside that of Prometheus.
