The peculiar evil of silencing the expression of an opinion is that it is robbing the human race； posterity as well as the existing generation； those who dissent from the opinion， still more than those who hold it.

不要为了得到世界而失去你的灵魂，智慧比金银更宝贵。

Stupid is as stupid does.

Don't watch the clock; do what it does. Keep going.
