There is no great gulf between youth and middle age, as there is between childhood and youth. Adults are little more than grown-up children. This is what makes their arrogance so insulting,--the assumption that they have acquired any impartiality or objectivity of outlook, and have any better standards for judging life. Their ideas are wrong, and grow progressively more wrong as they become older. Youth, therefore, has no right to be humble. The ideals it forms will be the highest it will ever have, the insight the clearest, the ideas the most stimulating. The best that it can hope to do is to conserve those resources, and keep its flame of imagination and daring bright. Therefore, it is perhaps unfair to say that the older generation rules the world. Youth rules the world, but only when it is no longer young. It is a tarnished, travestied youth that is in the saddle in the person of middle age. Old age lives in the delusion that it has improved and rationalized its youthful ideas by experience and stored-up wisdom, when all it has done is to damage them more or less--usually more. And the tragedy of life is that the world is run by these damaged ideals. That is why our ideas are always a generation behind our actual social conditions. Press, pulpit, and bar teem with the radicalisms of thirty years ago. The dead hand of opinions formed in their college days clutches our leaders and directs their activities in this new and strangely altered physical and spiritual environment. Hence grievous friction, maladjustment, social war. And the faster society moves, the more terrific is the divergence between what is actually going on and what public opinion thinks is actually going on. It is only the young who are actually contemporaneous; they interpret what they see freshly and without prejudice; their vision is always the truest, and their interpretation always the justest. Youth does not simply repeat the errors and delusions of the past, as the elder generation with a tolerant cynicism likes to think; it is ever laying the foundations for the future. What it thinks so wildly now will be orthodox gospel thirty years hence. The ideas of the young are the living, the potential ideas; those of the old, the dying, or the already dead. This is why it behooves youth to be not less radical, but even more radical, than it would naturally be. It must be not simply contemporaneous, but a generation ahead of the times, so that when it comes into control of the world, it will be precisely right and coincident with the conditions of the world as it finds them. If the youth of to-day could really achieve this miracle, they would have found the secret of “perpetual youth.” * * * * *
