西塞罗（Marcus Tullius Cicero，前106年1月3日–前43年12月7日），古罗马著名政治家、哲人。
“Six mistakes mankind keeps making century after century:
1. Believing that personal gain is made by crushing others;
2. Worrying about things that cannot be changed or corrected;
3. Insisting that a thing is impossible because we cannot accomplish it;
4. Refusing to set aside trivial preferences;
5. Neglecting development and refinement of the mind;
6. Attempting to compel others to believe and live as we do.”
人类一个世纪又一个世纪犯六个错误:
1. 相信个人利益是通过压榨他人获得的;
2. 担心那些无法改变或纠正的事情;
3. 坚持认为做这件事是不可能的，因为我们不能完成它;
4. 拒绝搁置那些不重要的偏好;
5. 忽视心智的发展和升华;
6. 试图强迫别人跟我们一样去信仰和生活。”
The wise are instructed by reason, average minds by experience, the stupid by necessity and the brute by instinct.
聪明人凭理智办事，平常人凭经验办事，愚蠢人凭需要办事，牲畜凭本能办事。
If you have a garden and a library, you have everything you need.
如果你有一个花园和一个图书馆，你就有了你需要的一切。
