A lovely, pure, noble, and most moral nature, without the strength of nerve which forms a hero, sinks beneath a burden which it cannot bear, and must not cast away. All duties are holy for him; the present is too hard. Impossibilities have been required of him; not in themselves impossibilities, but such for him. He winds, and turns, and torments himself; he advances and recoils, is ever put in mind, ever puts himself in mind; at last does all but lose his purpose from his thoughts; yet still without recovering his peace of mind.

Johann Wolfgang von Goethe
