Modern art is generally understood to be any art created between the late 19th century and the 1970s. Following the emergence of photography, art was no longer needed as direct representation so artists turned to abstraction and experimentation. Modern art is a blanket term for all artistic movements in this period, as well as the avant-garde. Postmodern art is generally believed to be in some way opposed to an aspect of modern art, experimenting with genres, cultures and mediums not previously considered. It is art following modern art, and some areas of contemporary art. It accepts past styles and traditions, unlike modern art, as well as embracing new media. Lyotard did not distinguish modern art and postmodern art in the traditional way described above, he believed that postmodern art was always at work within modern art; it is the avant-garde in all its forms, it is whatever is new and progressive about modern art, forcing it into new territory. He therefore said that something must be postmodern (new and disruptive) before it can become modern (acceptable). Although the postmodern eventually becomes the modern, it never entirely loses its ability to shock and disturb. He believed that modern art showed us that the unpresentable exists, while postmodern art attempted to present it. This paradoxical task leaves in the viewer a mixture of pleasure and pain, known as Kantian sublime. Lyotard thought the ultimate task of art to be presenting the unpresentable, which is fulfilled by the avant-garde, in which matters of taste and public opinion simply aren’t important. The sublime is the feeling when the imagination is pushed to the limit, causing pain as the individual is faced with something beyond them, which they have no control over and are faced with their true position in the world. Pleasure follows this as our reason reasserts itself and we become aware of the superiority of human reason over perception. The mathematical sublime is when we are confronted with an object unbelievably large, so we cannot see and comprehend it as a whole. The dynamical sublime refers to our confrontation with something far more powerful than us, in which case we are aware of our own mortality and insignificance. Having looked at Lyotard’s postmodernism and postmodern art in detail, with both Lyotard’s examples and my own, I will conclude with a brief examination of the works of Anderson and Jameson, as they provide arguments both for and against Lyotard’s work, taking their own examples to illustrate points made.
