"Mankind is growing up. The rest of history for three and twenty centuries is threaded with the spreading out and development and interaction and the clearer and more effective statement of these main leading ideas. Slowly more and more men apprehend the reality of human brotherhood, the needlessness of wars and cruelties and oppression, the possibilities of a common purpose for the whole of our kind. In every generation thereafter there is the evidence of men seeking for that better order to which they feel our world must come. But everywhere and wherever in any man the great constructive ideas have taken hold, the hot greeds, the jealousies, the suspicions and impatience that are in the nature of every one of us, war against the struggle towards greater and broader purposes. The last twenty-three centuries of history are like the efforts of some impulsive, hasty immortal to think clearly and live rightly. Blunder follows blunder; promising beginnings end in grotesque disappointments; streams of living water are poisoned by the cup that conveys them to the thirsty lips of mankind. But the hope of men rises again at last after every disaster. . . . We pass on now to the story of one futile commencement, one glorious shattered beginning of human unity. There was in Alexander the Great knowledge and imagination, power and opportunity, folly, egotism, detestable vulgarity, and an immense promise broken by the accident of his early death while men were still dazzled by its immensity."
