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.

Even a paranoid can have enemies.

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.

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