Context: I am beginning with the young. We older ones are used up. Yes, we are old already. We are rotten to the marrow. We have no unrestrained instincts left. We are cowardly and sentimental. We are bearing the burden of a humiliating past, and have in our blood the dull recollection of serfdom and servility. But my magnificent youngsters! Are there finer ones anywhere in the world? Look at these young men and boys! What material! With them, I can make a new world.
