社会为了省事，把人活生生剪成正反两面的“纸片人”，贴在墙上当路标。人为塑造英雄与败类，其实都是在对人性进行以偏概全的定义。没有什么不对，人性本就如此。

To save effort, society shears people alive into two-dimensional “paper figures” and pastes them on the wall as signposts. The artificial creation of heroes and villains is, in truth, defining human nature through generalizations. There is nothing wrong with this; it is simply how human nature is.
