But for three centuries men have been studying the facts of existence from an entirely different side from that whence the church takes its outlook. They have been finding out all kinds of curious facts, totally unconnected with any supernatural sphere. First, they made such discoveries as that the world is not flat, but round; not stationary, but doubly revolving. And so they went on. The stars, the plants, the animals, the human body, yielded all manner of curious knowledge. New powers came into men's hands through this knowledge; new avenues to happiness were opened. Facts wove themselves together in wider and wider combinations. Orderly procedure was found where there had seemed such confusion as only capricious spirits could occasion. It is learned, too, that even as the individual man has grown up from babyhood, so the race of man has grown up from the beast. The globe itself has grown from a simple origin into infinite diversity and complexity. There has been a universal, orderly growth,--what we name "Evolution." And it is learned that all mental phenomena, so far as we can explore them, stand in some close relation to a physical basis in the brain, and to a train of physical antecedents. And now the men who have come up by the path of this knowledge stand face to face with the men who have been climbing in the path whose signboards are such as "Duty," "Worship," "Aspiration;" and the question arises, Do our paths lie henceforth together, or do they separate, and is the one party losing its travel? Perhaps the best example of the union of the two pursuits in one man is given by Benjamin Franklin. Franklin worked out, through a very genuine, homely, and personal experience, the conviction that _moral perfection_ is the only true aim. He reached this conviction while still a young man, and in the main tenor of his life he was faithful to it. He made no vaunt of his religion, founded no sect, gave his words and deeds chiefly to practical affairs; and perhaps few guessed, until at the close of his life he told his own story with consummate charm, that the secret motive and mainspring of his life had been the same that animates the saints and saviors,--the thirst for moral perfection. The motive and method had been hidden, but the result had long been clear to the eyes of the whole world. Franklin's character was reverenced alike in the court of France and the farmhouses of Pennsylvania and New England. To the Old World he seemed the heroic and coming man of the New World, side by side with Washington. The Virginian embodied the highest traditional virtues of the race, self-mastery, patience, magnanimity, devotion to the common good; the Pennsylvanian, if less called on for the heroic forms of antique virtue, added to its substance new traits of wisdom, progress, and happiness,--signs of a better age to be.
