The eleventh section of Daode jing (Tao Te Ching), the foundational text of Taoism, reads: . . . Thirty spokes share a hub; Because [the wheel] is empty, it can be used in a cart. Knead clay to make a vessel. Because it is empty, it can function as a vessel. Carve out doors and windows to make a room. Because they are empty, they make a room usable. Thus we possess things and benefit from them, But it is their emptiness that makes them useful. . . This section has always been appreciated as a supreme piece of rhetoric on the powers of nothingness, a philosophical concept fiercely articulated in the Daode jing. Whereas that may indeed be the author’s intention, the empirical evidence evoked to demonstrate this concept reveals an alternative way of seeing manufactured objects by focusing on their immaterial aspects. This way of looking at things has important implications for archaeological and art historical scholarship on ancient artifacts and architecture precisely because these two disciplines identify themselves with the study of physical remains of the past so firmly that tangibility has become an undisputed condition of academic research in these fields. Archaeologists routinely classify objects from an excavation into categories based on material and then inventory their sizes, shapes, and decoration. Art historians typically start their interpretation of images, objects, and monuments by identifying their formal attributes. Whereas such trained attention to material and formal evidence will surely persist for good reasons, the Daode jing section cautions us of the danger of ignoring the immaterial aspects of man-made forms, which, though eluding conventional typological classification and visual analysis, are nevertheless indispensible to their existence as objects and buildings. The current chapter incorporates this approach into a study of ancient Chinese art and visual culture by arguing that constructed empty spaces on artifacts and structures—holes, vacuums, doors, and windows—possess vital significance to understanding the minds and hands that created them and thus deserve a serious look into their meaning.
