Shall a nation be moulded at last.”

Speech to the Budget Commission of the Prussian Diet (30 September 1862), published in Fürst Bismarck als Redner, Vol. 2 (after 1881), edited by Wilhelm Böhm, p. 12 http://books.google.de/books?id=3WsIAAAAQAAJ&pg=PA12); after some objections to his initial speech Bismarck returned to the podium and declared:
::Auswärtige Conflicte zu suchen, um über innere Schwierigkeiten hinwegzukommen, dagegen müsse er sich verwahren; das würde frivol sein; er wolle nicht Händel suchen ; er spreche von Conflicten, denen wir nicht entgehen würden, ohne daß wir sie suchten.
:: I must protest that I would never seek foreign conflicts just to go over domestic difficulties; that would be frivolous. I was speaking of conflicts that we could not avoid, even though we do not seek them.

“On Tactics Against Japanese Imperialism” (December 27, 1935)

As quoted in India Calling (1946) by himself and R. I. Paul, p. 5

Jean-Christophe (1904 - 1912), Journey's End: The Burning Bush (1911)
Context: Christophe returned to the Divine conflict.... How his own fight, how all the conflicts of men were lost in that gigantic battle, wherein the suns rain down like flakes of snow tossing on the wind!... He had laid bare his soul. And, just as in those dreams in which one hovers in space, he felt that he was soaring above himself, he saw himself from above, in the general plan of the world; and the meaning of his efforts — the price of his suffering, were revealed to him at a glance. His struggles were a part of the great fight of the worlds. His overthrow was a momentary episode, immediately repaired. Just as he fought for all, so all fought for him. They shared his trials, he shared their glory.
"Companions, enemies, walk over me, crush me, let me feel the cannons which shall win victory pass over my body! I do not think of the iron which cuts deep into my flesh, I do not think of the foot that tramples down my head, I think of my Avenger, the Master, the Leader of the countless army. My blood shall cement the victory of the future...."
