If one would have a friend, then must one also be willing to wage war for him: and in order to wage war, one must be CAPABLE of being an enemy.

Context

“And often with our love we want merely to overleap envy. And often we attack and make ourselves enemies, to conceal that we are vulnerable.
“ Be at least mine enemy! ” —thus speaketh the true reverence, which doth not venture to solicit friendship.
If one would have a friend, then must one also be willing to wage war for him: and in order to wage war, one must be CAPABLE of being an enemy. One ought still to honour the enemy in one’s friend. Canst thou go nigh unto thy friend, and not go over to him?
In one’s friend one shall have one’s best enemy. Thou shalt be closest unto him with thy heart when thou withstandest him.
