Hidden behind the horizons, living men unite with machines and fall furiously on space. They do not see their shots. They do not know what they are doing. "You shall not know; you shall not know."
But since the cannonade is returning, they will be fighting here again. All these battles spring from themselves and necessitate each other to infinity! One single battle is not enough, it is not complete, there is no satisfaction. Nothing is finished, nothing is ever finished. Ah, it is only men who die! No one understands the greatness of things, and I know well that I do not understand all the horror in which I am.
