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

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

Secrets are rarely betrayed or discovered according to any program our fear has sketched out.

We must not always talk in the marketplace of what happens to us in the forest.

The first duty of a good inquisitor is to suspect especially those who seem sincere to him.

There is nothing more deceptive than an obvious fact.

Nothing is hidden from the eyes of the observing world.

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.

It was funny how I could feel all alone and under surveillance at the same time.

A regime which combines perpetual surveillance with total indulgence is hardly conducive to healthy development.

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.

Spies are of no use nowadays. Their profession is over. The newspapers do their work instead.
