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

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

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

There is nothing more deceptive than an obvious fact.

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.

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

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

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

Even a paranoid can have enemies.

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

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

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