100 Percent Pure German Sweat

I’m going to try something a bit different for this section. Three quotes (posted below) stood out to me in this section. My question is this: How are these quotes related to each other, to the setting of the novel, and to the current state of the world?

“[Humans’] great skill is their capacity to escalate.”

“There was no swaying [the crowd], squeezing it, or reasoning with it. You breathed with it, and you sang its songs. You waited for its fire.”

“[Ludwig] was just an animal, hurt among the melee of his own kind, soon to be trampled by it.”
