I sound my barbaric yawp on the roofs of the world.

- Walt Whitman

"O me! O life!... of the questions of these recurring;
Of the endless trains of the faithless--of cities fill'd with the foolish;
Of myself forever reproaching myself, (for who more foolish than I, and who more faithless?)
Of eyes that vainly crave the light--of the objects mean--of the struggle ever renew'd;
Of the poor results of all--of the plodding and sordid crowds I see around me;
Of the empty and useless years of the rest--with the rest me intertwined;

The question, O me! so sad, recurring--What good amid these, O me, O life?

Answer:

That you are here. That life exists, and identity;
That the powerful play goes on, and you will contribute a verse."

- Walt Whitman

"What will your verse be?"
- Keating in Death Poet's Society
