Man is a rope, tied between beast and overman--a rope
over an abyss. A dangerous across, a dangerous on-the-way,
a dangerous looking-back, a dangerous shuddering and
stopping. What is great in man is that he is a bridge and
not an end: what can be loved in man is that he is an overture
and a going under. I love those who do not know how to
live, for they are those who cross over.
