However, we distinguish between practical "application" or practice of postmodern theory and the "expression" of postmodern theory; we reserve the arts for the function of delivering that expression.
In the study of the postmodern literature and the arts, the notion of "theory" predominates. We try to differentiate between literary and artistic theory ("critical theory") on the one hand and literary practice ("expression") on the other hand. Theoretical concepts operating in postmodern social and political criticism differ mainly in emphasis from those operating in the criticism and analysis of literature and the arts. (There is an appearance in this of a greater theoretical unity to postmodernism than we usually are willing to acknowledge.)
With the power of hypertext to link and jump, we assume that we can bridge smoothly what may appear to be (and may in fact be) too nice a distinction for the practical discussion of literature and the arts. Never deny us the privilege, whenever such categorical complexities fall of their own weight, to make a major revision in THE PROGRAMME.
With the postmodern inclination to include all texts in the realm of the creative, how can we know what artifacts--what texts--qualify for inclusion under the rubric of creative expression? Well, our decisions may smack of the arbitrary. They may also come from a rough and ready sense of the approximate. If it looks like an old-time duck, maybe it's a newfangled duck, and we will include it.
Forms of expression have not died; they have been contextualized. We can recognize them for what they are (or may be), and that helps us. At the same time, they do not mesmerize us or dragoon us into categorical behaviors that would make us look silly in this porous day and age.
McHale has argued that postmodern fiction is mimetic, a formal performance that imitates our postmodern experience; we take some old-time comfort from that familiar posture (although we are not sure how he gets away with it).
The section of THE PROGRAMME on creative expression, then, is made up of the following groupings:
