We must remember that this is a world of progress, a world of change. There is perpetual death and there is perpetual birth. By the grave of the old forever stands youth and joy; and, when an old religion dies, a better one is born. When we find out that an assertion is a falsehood, a shining truth takes its place, and we need not fear the destruction of the false. The more false we destroy the more room there will be for the true. There was a time when the astrologer sought to read in the stars the fate of men and nations. The astrologer has faded from the world, but the astronomer has taken his place. There was a time when the poor alchemist, bent and wrinkled and old, over his crucible, endeavored to find some secret by which he could change the baser metals into purest gold. The alchemist is gone; the chemist took his place; and, although he finds nothing to change metals into gold, he finds something that covers the earth with wealth. There was a time when the soothsayer and auger flourished, and after them came the parson and the priest; and the parson and priest must go. The preacher must go, and in his place must come the teacher--that real interpreter of nature. We are done with the supernatural. We are through with the miraculous and the wonderful. There was once a prophet who pretended to read in the book of the future. His place was taken by the philosopher, who reasons from cause to effect--a man who finds the facts by which he is surrounded and endeavors to reason from these premises, and to tell what in all probability will happen in the future. The prophet is gone, the philosopher is here. There was a time when man sought aid entirely from heaven--when he prayed to the deaf sky. There was a time when the world depended upon the supernaturalist. That time in Christendom has passed. We now depend upon the naturalist--not upon the disciple of faith, but upon the discoverer of facts--upon the demonstrator of truth. At last we are beginning to build upon a solid foundation, and just as we progress the supernatural must die.
