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

Once suspicion is aroused, everything feeds it.

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

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

There is nothing more deceptive than an obvious fact.

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.

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

Three may keep a secret, if two of them are dead.

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

If the world were good for nothing else, it is a fine subject for speculation.

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

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.
