Eutrapelia. "A happy and gracious flexibility," Pericles calls this quality of the Athenians...lucidity of thought, clearness and propriety of langua… - Matthew Arnold

For what wears out the life of mortal men?
'Tis that from change to change their being rolls:
'Tis that repeated shocks, again, again,
Exhaust the energy of the strongest souls,
And numb the elastic powers.
Till having us'd our nerves with bliss and teen,
And tir'd upon a thousand schemes our wit,
To the just-pausing Genius we remit
Our worn out life, and are — what we have been.

- The Scholar Gipsy

But often, in the world’s most crowded streets,
But often, in the din of strife,
There rises an unspeakable desire
After the knowledge of our buried life;
A thirst to spend our fire and restless force
In tracking out our true, original course;
A longing to inquire
Into the mystery of this heart which beats
So wild, so deep in us — to know
Whence our lives come and where they go.

And each day brings it's pretty dust,
Our soon-choked souls to fll
And we forget because we must,
And not because we will.
