How we cite our quotes: (Volume.Chapter.Paragraph.)
Quote #4
He thought, this is how men feel, trapped in a shell hole; this room is not an accident of poverty, it's the footprint of a war [....] (2.11.160)
The scene is interesting because of the imagery Roark uses. Here he talks about a "shell hole" and goes on to use images of war, and particularly of World War I to describe his tense and demoralizing encounter with Mallory.
Quote #5
Nobody had ever heard of them, but they were Councils and this gave weight to their voice. (2.12.38)
Rand frequently critiques American bureaucracy throughout the book, and here she tackles the way people cede power and influence to groups just because they call themselves "Councils."
Quote #6
It was a pedestal from which a god had been torn, and in his place there stood, not Satan with a sword, but a corner lout sipping a bottle of Coca-Cola. (3.8.53)
This sounds like the lyrics to a folk song. Rand mashes up religion and American pop culture here, emphasizing how "evil" commonplace things (a dude drinking a Coke) can be by comparing the image to Satan.
