My enemies make appointments at my tomb.

The most constant, the most powerful, and the most generous of all my enemies [Britain].

Powerful enemies must be out-fought and out-produced.

My friends, judge me by the enemies I have made.

Do I not destroy my enemies when I make them my friends?

Man is very well defended against himself... The actual fortress is inaccessible, even invisible to him, unless his friends and enemies play the traitor and conduct him in by a secret path.
