I will never again command an army in America if we must carry along paid spies. I will banish myself to some foreign country first.

Guard more faithfully the secret which is confided to you than the money which is entrusted to your care.

Secrets define us, they mark us, they set us apart from all the others. The secrets which we preserve provide a key to who we are, deep down.

Secrecy lies at the very core of power.

For sooner will men hold fire in their mouths than keep a secret.

To know all is not to forgive all. It is to despise everybody.

There is nothing more deceptive than an obvious fact.

There is a sickness among tyrants: they cannot trust their friends.

Even a paranoid can have enemies.
