Even if you place your hand inside the artwork, it does not break, and its existence is maintained. You realize that the artwork is just ordinary water. The artwork does not exist by itself; the distinctive phenomenon created by the unique environment is the existence of the artwork.

The artwork is freed from physical matter. Everyday substances like air, water, and light become phenomena through the unique environment, and these phenomena constitute the existence of the artwork. The artwork is inseparable from the environment and changes along with it. It transcends the various notions of existence through physical objects. Even if the artwork breaks, it is repaired. Conversely, if the environment is not maintained, the artwork will disappear. The outlines of the artwork's existence are ambiguous, and it is continuous with the environment. Perhaps, people's consciousness will spread from the artwork itself to the environment.

When the viewer moves, the location and color of the artwork change. The artwork seen by the viewer is visible only to that viewer. For the person next to them, the artwork is in a different location and has a different color. In other words, the artwork being seen does not exist in the physical world but exists in the viewer's cognitive world. We refer to such artworks that exist in the perceived world as Cognitive Sculpture. When it exists within perception, it is considered to exist.
