“And yet to be without hope is almost to be without sanity.”

Source: Work Without Hope (1825), l. 9.
Context: Bloom, O ye Amaranths! bloom for whom ye may,
For me ye bloom not! Glide, rich streams, away!
With lips unbrightened, wreathless brow, I stroll:
And would you learn the spells that drowse my soul?
Work without Hope draws nectar in a sieve,
And Hope without an object cannot live.

Alternate translation: Hope not without despair, despair not without hope. (translated by Zachariah Rush).

Context: If Dahlmann was without hope, he was also without fear. As he crossed the threshold, he felt that to die in a knife fight, under the open sky, and going forward to the attack, would have been a liberation, a joy, and a festive occasion, on the first night in the sanitarium, when they stuck him with the needle. He felt that if he had been able to choose, then, or to dream his death, this would have been the death he would have chosen or dreamt. Firmly clutching his knife, which he perhaps would not know how to wield, Dahlmann went out into the plain.
