真相很少是纯粹的，也从来不是简单的。
The truth is rarely pure and never simple.
The future belongs to those who prepare today.
Think globally, act locally.
The ocean is not a bottomless pit; resources are limited, and only by respecting nature can we achieve long-term development.
错误同真理的关系，就象睡梦同清醒的关系一样。一个人从错误中醒来，就会以新的力量走向真理。
