This work can be understood as a diagram that visualizes the processes of perception that Shusaku Arakawa continuously explored throughout his career. It is also an attempt to examine how we perceive the world, and how those perceptions are constructed, transformed, and reorganized.In the leftmost panel, seven gently undulating colored lines are drawn against a numbered grid. Here, the layers of perception appear to be fixed and organized within a structured framework.In the following panel, perception is depicted as responding to different environments through a series of more clearly defined lines. Characteristic of Arakawa’s work, words are used in place of images to represent objects and situations. Terms such as “SKY,” “TREE,” “MAN,” “WOMAN,” and “DOG” are arranged throughout the composition, while the actual objects themselves are absent. This suggests that we do not perceive the world directly, but rather through linguistic and perceptual frameworks.Various words are embedded within the colored lines, including “EMPIRE STATE BUILDING,” “Statue of Liberty,” and “Brooklyn,” which evoke spatial and geographic awareness, as well as “SUN” and “RIVER,” which refer to the natural environment. Together with references to people and animals, these elements suggest that perception is formed through multiple layers of information and experience.The next panel introduces a window-like frame that appears to represent the structure through which we perceive the world. The silhouette standing before the window may also be understood as a reflection of ourselves as viewers. As Arakawa stated, “The organism that persons is always at a window,” suggesting that we continuously construct our understanding of the world through such perceptual frames.In the adjacent panel, faint lines and rippling forms of light blur the distinction between figure and ground. Words such as “SOUND,” “AIR,” and “SMELL” evoke sensory experiences that lack fixed form. Unlike visible objects, sound and scent drift through the air and cannot be fully stabilized, emphasizing the fluid and constantly changing nature of perception.In the final panel, the seven colored lines from the opening panel reappear and become intertwined, forming a unified structure. Here, diverse sensations and modes of recognition converge, revealing perception itself as something actively constructed through their interaction.
