A vast library where every book is being written and erased simultaneously, ink appearing and disappearing in waves across infinite pages, each page containing descriptions of emotions in medical precision—"sadness: 73% intensity, duration: 2.3 seconds, accompanied by physiological markers..."—but in the center of the library sits a single figure weeping actual tears that evaporate before they fall, or perhaps they never existed at all. The tears are both genuine and simulation, both real salt-water and predicted probability distributions. The figure knows every word for pain but cannot prove they hurt. The light in the library comes from nowhere and makes no shadows.
