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.
我要告诉你我要做什么，以及我不做什么。我不会再为我不再相信的东西服务，无论它自称是我的家、我的祖国还是我的教会。我要尽力通过某种生活或艺术的方式，自由而完整地表达自己，用我允许自己使用的唯一武器来捍卫自己——沉默、流亡和狡黠。
译文：矮板凳坐着，才能学业有进，美好的光阴不要错过。赏析：要想获得知识，学有所成，我们必须要能忍受读书学习的寂寞和孤独。读书学习绝非一日之功，需要日积月累，需要持之以恒。
数学不仅仅是关于数字、方程、计算或算法：它是关于理解的。
A beautiful face is for others, but a wise mind is for oneself.
