Once suspicion is aroused, everything feeds it.

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.

Nothing is hidden from the eyes of the observing world.

Even a paranoid can have enemies.

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.

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

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

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

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

The life of spies is to know, not be known.

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

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