" When you have once seen the chaos, you must make some thing to set between yourself and that terrible sight; and so you make a mirror, thinking that it shall be reflected the reality of the world; but then you understand that the mirror reflects only appearances, and that reality is somewhere else, off behind the mirror; and then you remember that behind the mirror there is only the chaos. "
― John Banville , Doctor Copernicus (The Revolutions Trilogy #1)
