This article examines a changing global reality that manifests itself in new forms of social activism. The struggle of the multitude challenges political representation and contemporary art seems to corroborate this observation. Becoming a form of social intervention, it turns into an active force and leaves behind the need to double action with representation, representational practices being the hallmark of classical art. A new theory of the image would have to incorporate this dynamic: it would have to treat and develop (...) the basic categories of action and relation. There are few philosophies of the act, and the existing semiotic models mostly deal with dual structures (signifier/signified; sign/meaning; image/referent, and so on). It is necessary to sketch out a dynamic theory of the image that would: (1) reveal the limitations of the concept of representation; (2) conceive of the image as a set of multiple changing relations. The image would thus be seen as a necessary part of the relations governing the world in its entirety, that is, as part of the movement of matter itself. Which is another way of saying that those relations are actualized, or expressed, in the image. (shrink)
