I feel at times with all my learned pains,

As if a weight of lead were at my heart,

And palsy on my brains.

How high to climb up learning’s lofty stair,

How hard to find the helps that guide us there;

And when scarce half the way behind him lies,

His glass is run, and the poor devil dies!

Faust.

The parchment-roll is that the holy river,

From which one draught shall slake the thirst for ever?
