Sometimes it is more important to discover what one cannot do, than what one can do.

Where there are too many policemen, there is no liberty. Where there are too many soldiers, there is no peace. Where there are too many lawyers, there is no justice.

I am willing to allow that smoking is a moral weakness, but on the other hand, we must beware of the man without weaknesses. He is not to be trusted. He is apt to be always sober and he cannot make a single mistake. His habits are likely to be regular, his existence more mechanical and his head always maintains its supremacy over his heart. Much as I like reasonable persons, I hate completely rational beings.

We should not expect people to be good, but should make it impossible for them to be bad.

The busy man is never wise and the wise man is never busy.

The end of living is the true enjoyment of it.
