But these are foolish things to all the wise,
And I love wisdom more than she loves me;
My tendency is to philosophise
On most things, from a tyrant to a tree;
But still the spouseless virgin Knowledge flies,
What are we? and whence come we? what shall be
Our ultimate existence? What’s our present?
Are questions answerless, and yet incessant.

Lord Byron, Don Juan (1818-24), Canto VI, Stanza 63
