  In an analogy that some philosophers (e.g., Arthur C. Danto 1993, 199–200) have taken quite seriously, the vehicle is to the work as the body is to the person; for a very early remark in this vein, see Johan Georg Sulzer (1792, vol. 4, 727), who declares that the work of art has both body (the artistic material or Stoff), and soul or Geist (the representation or Darstellung). Another way of motivating the distinction in aesthetics is to say, along with Pepper and others, that reference to the vehicle or artistic structure alone does not suffice to identify the object of critical evaluation, or what artistic and aesthetic appreciation is really about.
