If they could only live therein! Just as towns are shaken by an avalanche and become desolate, and man builds his house there in fear and for a season only; so life is broken in sunder and becomes weak and spiritless, if the avalanche of ideas started by science take from man the foundation of his rest and security, the belief in what is stable and eternal. Must life dominate knowledge, or knowledge life? Which of the two is the higher, and decisive power? There is no room for doubt: life is the higher, and the dominating power, for the knowledge that annihilated life would be itself annihilated too. Knowledge presupposes life, and has the same interest in maintaining it that every creature has in its own preservation. Science needs very careful watching: there is a hygiene of life near the volumes of science, and one of its sentences runs thus:--The unhistorical and the super-historical are the natural antidotes against the overpowering of life by history; they are the cures for the historical disease. We who are sick of the disease may suffer a little from the antidote. But this is no proof that the treatment we have chosen is wrong. And here I see the mission of the youth that forms the first generation of fighters and dragon-slayers: it will bring a more beautiful and blessed humanity and culture, but will have itself no more than a glimpse of the promised land of happiness and wondrous beauty. This youth will suffer both from the malady and its antidotes: and yet it believes in strength and health and boasts a nature closer to the great Nature than its forebears, the cultured men and graybeards of the present. But its mission is to shake to their foundations the present conceptions of "health" and "culture," and erect hatred and scorn in the place of this rococo mass of ideas. And the clearest sign of its own strength and health is just the fact that it can use no idea, no party-cry from the present-day mint of words and ideas to symbolise its own existence: but only claims conviction from the power in it that acts and fights, breaks up and destroys; and from an ever heightened feeling of life when the hour strikes. You may deny this youth any culture--but how would youth count that a reproach? You may speak of its rawness and intemperateness--but it is not yet old and wise enough to be acquiescent. It need not pretend to a ready-made culture at all; but enjoys all the rights--and the consolations--of youth, especially the right of brave unthinking honesty and the consolation of an inspiring hope.
