Art redeems possibilities from oblivion. As Luhmann argues,
What art aspires to could . . . be described as the reactivation of eliminated possibilities. . . . Art points out that the scope of the possible is not exhausted and it therefore generates a liberating distance from reality. (Theory of Society, vol. 1. p. 210.)
We can imagine far more than what can actually happen, and art redeems these imaginings from oblivion. Philip Roth’s 2004 novel The Plot Against America might illustrate Luhmann’s point. In this alternate-history novel, Charles Lindbergh defeats Franklin Roosevelt in the 1940 presidential election. The consequences of electing the Nazi-sympathizing aviator are then narrated.
Luhmann also argues that art’s function
is to allow the world to appear in the world, to portray unity in unity, be it improved or (as now preferred) worsened. . . . The portrayal of the world in the world modifies the world itself in the sense of what is “not necessary as such.” The work of art provides its own proof of necessity–and this withholds it from the world. (210)
Though art is treated as an autopoietic function system along with politics, the economy, etc., art is also a symbolically generalized communication media. This is shown when Luhmann writes,
In contrast to other symbolically generalized communication media, art uses perceptual media or, in the case of narrative, visualization.
Symbolically generalized communication media are also called “success media” because they increase the probability of a communicative offering being accepted. For instance, monetary payment is the symbolically generalized communication media of the economy. If a person desires something and asking for it isn’t enough, then money can be offered. Money increases the probability of getting a yes. In politics, when simply asking for something to happen, as in asking citizens to pay taxes, isn’t enough, politics uses its power, which is backed up by the possibility of force or violence. Taxes can be forcefully taken because the political system has guns and jails, and people accept the legitimacy of the political system’s use of its guns and jails. Power is the “success media” of the political system.
There are only two possible responses to any communicative offering: yes or no. It’s a two-sided form. A yes means communication can continue, while a no means some other tack must be taken–a new communicative offering, such as more money or more power–if the communication is to succeed. To be successful, art must get a yes. It must be accepted as a communicative offering. It must be accepted as art.
Every work of art represents a selection or a series of selections from among potentially infinite possibilities. There are many choices an artist must make when it comes to choreographing a dance, writing a novel, designing a building, painting a picture, performing a line in a script, etc. But when a work of art is truly successful it seems that the selections the artist made were the only right selections. Any change to the work would damage it. If we change one word in a Shakespeare play, that would damage the play–or at least that is our belief. Thus the work of art seems necessary even though it is contingent. We feel that the play was written exactly as it was supposed to have been written even though there was never any “supposed to.” As Luhmann puts it,
Whether art can motivate people to accept the selections it offers depends on the individual work of art, making it plausible that it itself (as opposed to the world) has to be the way it is, even though it is made and no model for it exists anywhere. (211)
Only the art system can observe art as art. The economy can only observe it as exchange value. Health care observes is possible therapy. Education observes possible pedagogical uses. Religion observes possible signs of transcendent reality.
