The task of the decorative arts is to ornament utilitarian objects, such as rugs, textiles, lighting fixtures, etc. This is a valuable task, often performed by talented artists, but it is not an art in the esthetic-philosophical meaning of the term. The psycho-epistemological base of the decorative arts is not conceptual, but purely sensory: their standard of value is appeal to the senses of sight and/or touch. Their material is colors and shapes in nonrepresentational combinations conveying no meaning other than visual harmony; the meaning or purpose is concrete and lies in the specific object which they decorate.
As a re-creation of reality, a work of art has to be representational; its freedom of stylization is limited by the requirement of intelligibility; if it does not present an intelligible subject, it ceases to be art. On the other hand, a representational element is a detriment in the decorative arts: it is an irrelevant distraction, a clash of intentions. And although designs of little human figures or landscapes or flowers are often used to decorate textiles or wallpaper, they are artistically inferior to the nonrepresentational designs. When recognizable objects are subordinated to and treated as a mere pattern of colors and shapes, they become incongruous.
