“Why do we argue? Life's so fragile, a successful virus clinging to a speck of mud, suspended in endless nothing.”

Context: What does cause depression of spirits? Heavy head and heavy heart, and no sufficient reason for either, that I know of. I am out of doors every day, and have nothing unusual to trouble me; yet every interval of thought is clouded; there is no rebound, no rejoicing as it is my nature to rejoice, and as all things teach me to do. We are strange phenomena to ourselves, when we will stop to gaze at ourselves; but that I do not believe in; there are pleasanter subjects, and self is a mere speck on the great horizon of life.

Context: A soldier's life in combat is an endless series of decisions that mean success or failure, and perhaps life or death for himself or his comrades. The rifleman crawling through the rubble of a bombed-out street must decide on the best moment to escape enemy fire as he dodges from one doorway to the next. He must take a chance. The general seeking to break an enemy defense line and destroy his forces must decide just when and how to strike and precisely to what extent he dare weaken one sector of his front in order to mass overpowering strength at the main point of attack. He, too, must take a chance, although, in the stilted phraseology of military communiqués, he calls it a "calculated risk".
