Cheating is more honorable than stealing. 

He that will cheat you at play, will cheat you any way.

Grow your tree of falsehood from a small grain of truth.

Children and fools cannot lie. 

Alongside all swindlers the state now stands there as swindler-in-chief.

Credulity forges more miracles than trickery could invent.

We have to distrust each other. It is our only defense against betrayal.

There was no treachery too base for the world to commit.

If you steal, do not steal too much at a time. You may be arrested. Steal cleverly, little by little.

Life is the art of being well deceived.

Anyone who’s never experienced the pleasure of betrayal doesn’t know what pleasure is.

And, after all, what is a lie? ’Tis but the truth in masquerade.

In most cases men willingly believe what they wish.
