It is the contention of Clement Greenberg that the development of modern painting can be seen as a self-critical process whereby this art entrenches itself more firmly in its area of competence. The area of competence of each art, according to Greenberg, coincides with all that is unique to the nature of its medium. Each art form, then, has an essence (albeit one which is only revealed over time) and the constitutive limitations peculiar to painting are considered by Greenberg to be “the shape of the support, the properties of pigment” and above all “the flat surface.” At first sight such a formalist perspective appears to have the advantage of being able to offer an overall picture of the development of modern painting, a unified narrative leading from Manet to American abstract artists of Greenberg's own time, such as Jules Olitski. I shall be arguing here, however, that a clear gestalt is provided by Greenberg's theory only at the cost of eliminating consideration of meaning in art. My point is not that Greenberg gives too much attention to form and not enough to content, and that therefore we merely need to balance the scales. Simply to supplement Greenberg's discussion of the formal aspects of artworks with a consideration of their content would be to accept implicitly the strong division between these two aspects which he makes. It is that very separation which I am contesting: I do not believe that it is possible to make worthwhile statements about form whilst considering it, as Greenberg does, in a vacuum.
