I do not regret my youth and its beliefs. Up to now, I have wasted my time to live. Youth is the true force, but it is too rarely lucid. Sometimes it has a triumphant liking for what is now, and the pugnacious broadside of paradox may please it. But there is a degree in innovation which they who have not lived very much cannot attain. And yet who knows if the stern greatness of present events will not have educated and aged the generation which today forms humanity's effective frontier? Whatever our hope may be, if we did not place it in youth, where should we place it?
