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.

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.

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

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

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

There is nothing more deceptive than an obvious fact.

Secrecy lies at the very core of power.

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

Even a paranoid can have enemies.

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

Once suspicion is aroused, everything feeds it.

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