本不固者末必几。行不信者名必耗。
根本不稳固必然会央及枝叶。行为不守信必然会损害声誉。
说话过多会有不当之处,不如沉默寡言以保无虞。
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.
