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

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

There is nothing makes a man suspect much, more than to know little.

Secrecy lies at the very core of power.

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.

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

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.

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