For any social movement or development there must be a maximum limit beyond which it cannot proceed. That civilization which does not advance must decline, and so, when the maximum of development has been reached in any given direction, society must either retrograde or change the direction of its advance. There are many families of men that have failed, in the critical period of their economic evolution, to effect a change in direction, and were forced to fall back. Vanquished at the moment of their maximum, they have dropped out of the whirl of the world. There was no room for them. Stronger competitors have taken their places, and they have either rotted into oblivion or remain to be crushed under the iron heel of the dominant races in as remorseless a struggle as the world has yet witnessed. But in this struggle fair women and chivalrous men will play no part. Types and ideals have changed. Helens and Launcelots are anachronisms. Blows will be given and taken, and men fight and die, but not for faiths and altars. Shrines will be desecrated, but they will be the shrines, not of temples, but market-places. Prophets will arise, but they will be the prophets of prices and products. Battles will be waged, not for honor and glory, nor for thrones and sceptres, but for dollars and cents and for marts and exchanges. Brain and not brawn will endure, and the captains of war will be commanded by the captains of industry. In short, it will be a contest for the mastery of the world's commerce and for industrial supremacy. It is more significant, this struggle into which we have plunged, for the fact that it is the first struggle to involve the globe. No general movement of man has been so wide-spreading, so far-reaching. Quite local was the supremacy of any ancient people; likewise the rise to empire of Macedonia and Rome, the waves of Arabian valor and fanaticism, and the mediaeval crusades to the Holy Sepulchre. But since those times the planet has undergone a unique shrinkage.
