We might view abstract art as falling into six basic categories. Three respond to nature: cosmologies, landscapes, and anatomies. And three respond to culture: fabrics, architecture, and signs. These categories are not mutually exclusive. It often happens, for instance, that cosmological images include anatomical imagery or that images inspired by fabric patterns include drawn or written signs.

THE GOLDEN AGE OF ABSTRACTION: RIGHT NOW
How do we make sense of all this activity in a type of art that was declared dead 40 years ago? I believe the most useful way to understand abstraction is not in terms of its formal evolution (which does not, in any case, fit the linear models beloved of theoreticians) but in terms of thematic content. The formal qualities of an abstract painting or sculpture are significant not in themselves but as part of the work’s expressive message. Artists work by reviving and transforming archetypes from the unconscious of modern culture. Therefore, the most useful questions to ask about contemporary abstract painting or sculpture are: What themes and forms does it retrieve from the tradition of modern art? How have they been changed? And how has the artist used them to express the social, political, and spiritual experience of our own time?
