Sacred dread, that is the best part of humans. As much as the world makes them pay for what they feel, it is in shock that they feel prodigious reality profoundly.
Another translation renders this phrase thusly:
A shudder’s the truest sign of humanity:
Though the world is such we may not feel it,
Once seized by it, we feel Immensity deeply.
- from Faust, Goethe
