When we come to deal with human values, we find that we can trace much the same kind of evolution. Back in the days of the cave man, it was physical strength which dominated the horde; but nowadays, except in the imagination of the small boy, the "strong man" does not cut much of a figure. We go once, perhaps, to see him lift his heavy weights and break his iron bars, but then we are tired of him. Mere strength had to yield in the struggle for life to quickness of eye and hand, to energy which for lack of a better name we may call "nervous." The pugilist who has nothing but muscle goes down before his lighter antagonist who can keep out of his reach, and the crowd loves the football hero who can duck and dodge and make the long runs. One might cite a thousand illustrations, such as the British bowmen breaking down the heavily armored knights, or the quick-moving, light vessels of Britain overcoming the huge galleons of Spain. And as society develops and becomes more complex, the fighting man becomes less and less a man of muscle, and more and more a man of "nerve." Alexander, Caesar and Napoleon would have stood a poor chance in personal combat against many of their followers. They led, because they were men of energy and cunning, able to maintain the subtle thing we call prestige. Now the world has moved into an industrial era, and who are the great men of our time, the men whose lightest words are heeded, whose doings are spread upon the front pages of our newspapers? Obviously, they are the men of money. We may pretend to ourselves that we do not really stand in awe of a Morgan or a Rockefeller, but that we admire, let us say, an Edison or a Roosevelt. But Edison himself is a man of money, and will tell you that he had to be a man of money in order to be free to conduct his experiments. As for our politicians and statesmen, they either serve the men of money, or the men of money suppress them, as they did Roosevelt. The Morgans and the Rockefellers do not do much talking; they do not have to. They content themselves with being obeyed, and the shaping of our society is in their hands. And yet, some of us really believe that there are higher faculties in man than the ability to manipulate the stock market. We consider that the great inventor, the great poet, the great moralist, contributes more to human happiness than the man who, by cunning and persistence, succeeds in monopolizing some material necessity of human life. "Poets," says Shelley, "are the unacknowledged legislators of mankind." If this strange statement is anywhere near to truth, it is surely of importance that we should decide what are the higher powers in men, and how they may be recognized, and how fostered and developed.
