“O, mighty, divinely delimited wisdom of walls, boundaries! I is perhaps the most magnificent of all inventions. Man ceased to be a wild animal only when he build the first wall. Men ceased to be a wild man only when we built the Green Wall, only when, by means of that wall, we isolated our perfect machine world from the irrational, ugly world of trees, birds, and animals...”
“We talk of wild animals but man is the only wild animal. It is man that has broken out. All other animals are tame animals; following the rugged respectability of the tribe or type.”
“We live in a world that has walls and those walls need to be guarded by men with guns.”
“Why is it that when one man builds a wall, the next man immediately needs to know what's on the other side?”
“Always there are walls, Rachael, she persisted. Walls that block our path. Too high, too hard. We stop to rest, to gather strength, and before we know it we have lived whole lives in their shade. In time, we cease to even see them there, casting their long shadows, blocking our path. We cease to yearn for the other side.”
“What a world this would be if we just build bridges instead of walls!”
