“Architecture and three-dimensional art are of entirely opposite natures. The former is concerned with creating spaces with a specific function. In order not to fail in its purpose, architecture—whether or not it is a work of art—must be functional. Art is not functional. When three-dimensional art begins to take on some of the characteristics of architecture—for example, by creating functional spaces—it weakens its artistic function.”
— Sol LeWitt, excerpt from the catalogue Arte All’Arte II, 1997
