Laurence Sterne - The Life and Opinions of Tristram Shandy, Gentleman (Chap. 3.89) lyrics

 —But courage! gentle reader!—I scorn it—'tis enough to have thee in my power—but to make use of the advantage which the fortune of the pen has now gained over thee, would be too much—No—! by that all-powerful fire which warms the visionary brain, and lights the spirits through unworldly tracts! ere I would force a helpless creature upon this hard service, and make thee pay, poor soul! for fifty pages, which I have no right to sell thee,—naked as I am, I would browse upon the mountains, and smile that the north wind brought me neither my tent or my supper.  —So put on, my brave boy! and make the best of thy way to Boulogne.
