How strategic that epoch called the fourth century! He who sat in Caesar's palace looked out upon a dying empire. The old race was worn out with war and wine and wealth and luxury. Civilization seemed about to perish, and society was fast sinking back into barbarism. To the north of the Alps were the forest children, ruddy and robust, with their glorious youth full upon them. These young giants needed the dying language and literature and religion, and these great institutions needed their young, fresh blood. But between lay the granite walls builded from sea to sea. Now mark what Charles Kingsley called "the strategy of Providence." Suddenly a blind impulse fell upon the forest children. Two columns started southward. The one rested upon the North Sea and marched southeast; the other rested upon the Ural Mountains and marched southwest; the two met and converged upon Trieste. Without maps or military tactics or plans, wholly ignorant that Napoleon's favorite method of attack was being carried out by them, these two columns converged toward the Alpine pass, and for ten years pounded and pounded against the Roman walls until these yielded and fell. Then the forest children poured down into the vineyards and villages and cities of the dying empire. Multitudes remained to intermarry and preserve the dying race. Other multitudes returned to their old home to sow the northern forests with those great ideas that were to carry civilization through the long night of the dark ages. Another strategic hour came in the thirteenth century. Then all Europe was stirred with new and awakening life. It was dawn after darkness. Constantinople had fallen and scholars laden with manuscripts went forth to sow Europe with the new learning. The times were fully ripe for another great forward movement for society. Only one thing was lacking--great men for leaders. In that strategic crisis six leaders appeared. God gave each wing of the army of civilization a genius for its general. Copernicus overthrew superstition and brought in science; Luther gave religion, Gutenberg the printing-press, Calvin individualism, Michael Angelo art and the beautiful, Erasmus critical scholarship; and because the old world was filled with debris, and the new ideas needed room, Columbus gave the new world, offering what Emerson calls "the last opportunity of Providence for the human race." Surely this was a strategic moment in history, giving each citizen unique opportunity.
