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

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.

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

Secrecy lies at the very core of power.

The first duty of a good inquisitor is to suspect especially those who seem sincere to him.

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

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

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

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

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

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

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

Even a paranoid can have enemies.
