人的本性是天生的质朴；善良是王道教化的结果。
自知之明的人，不埋怨人；了解命运的人，不埋怨天；埋怨别人的人，遭遇穷困；埋怨上天的人，没有志向。

I will tell you what I will do and what I will not do. I will not serve that in which I no longer believe, whether it call itself my home, my fatherland, or my church: and I will try to express myself in some mode of life or art as freely as I can and as wholly as I can, using for my defence the only arms I allow myself to use—silence, exile, and cunning.
