"Not Chaos, not / The darkest pit of lowest Erebus, / Nor aught of blinder vacancy, scooped out / By help of dreams--can breed such fear and awe / As fall upon us often when we look / Into our Minds, into the Mind of Man-- / My haunt, and the main region of my song."

"On a poet's lips I slept / Dreaming like a love-adept / In the sound his breathing kept; / Nor seeks nor finds he mortal blisses, / But feeds on the aëreal kisses / Of shapes that haunt thought's wildernesses."

— Shelley, Percy Bysshe (1792-1822)
