"Brain of the New World, what a task is thine, To formulate the Modern — out of the peerless grandeur of the modern, Out of thyself, comprising science, to recast poems, churches, art, (Recast, may-be discard them, end them — maybe their work is done, who knows?) By vision, hand, conception, on the background of the mighty past, the dead, To limn with absolute faith the mighty living present."
