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.

Nothing is hidden from the eyes of the observing world.

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

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

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

Once suspicion is aroused, everything feeds it.

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

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

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

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

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

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