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

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.

If you read somebody’s diary, you get what you deserve.

There is nothing more deceptive than an obvious fact.

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

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