“And the conclusion is: Survive to reach it! Survive! At any price!
This is simply a turn of phrase, a sort of habit of speech: "at any price."
But then the words swell up with their full meaning, and an awesome vow takes shape: to survive at any price.
And whoever takes that vow, whoever does not blink before its crimson burst—allows his own misfortune to overshadow both the entire common misfortune and the whole world.
This is the great fork of camp life. From this point the roads go to the right and to the left. One of them will rise and the other will descend. If you go to the right—you lose your life, and if you go to the left—you lose your conscience.”
