城市的穷人就像树的根：看不见，但对生存至关重要。
The city's poor are like the roots of a tree: unseen, but essential to its survival.
The masses have no capacity for understanding complex issues.
未经审视的生活不值得过。
The longer life goes on, the fewer those around you to challenge your account of things, to remind you that life is not as you tell it, but as you remember it.
宇宙可以被理解这一事实是一个奇迹。
