“Where danger is, there must Johanna be”
Die Jungfrau von Orleans (The Maid of Orleans) http://www.gutenberg.org/etext/6792 (1801), Act II, Scene 4 (as translated by Anna Swanwick)
Context: Who dares impede my progress? Who presume
The spirit to control which guideth me?
Still must the arrow wing its destined flight!
Where danger is, there must Johanna be;
Nor now, nor here, am I foredoomed to fall;
Our monarch's royal brow I first must see
Invested with the round of sovereignty.
No hostile power can rob me of my life,
Till I've accomplished the commands of God.

Themselves contend in vain.”

Context: Folly, thou conquerest, and I must yield!
Against stupidity the very gods
Themselves contend in vain. Exalted reason,
Resplendent daughter of the head divine,
Wise foundress of the system of the world,
Guide of the stars, who art thou then if thou,
Bound to the tail of folly's uncurbed steed,
Must, vainly shrieking with the drunken crowd,
Eyes open, plunge down headlong in the abyss.
Accursed, who striveth after noble ends,
And with deliberate wisdom forms his plans!
To the fool-king belongs the world.
