Humans cannot communicate; not even their brains can communicate; not even their conscious minds can communicate. Only communication can communicate. - Niklas Luhmann

By representing themselves as a system [the mass media ] generates boundaries with an inside and an outside that is inaccessible to them. They too reflect [or represent] their outside as public life, so long as specific external relationships, such as to politics or to the advertisers, are not in question.

The art system operates on its own terms, but an observer of art can choose many different distinctions to indicate what he observes.

The activity of observing establishes a distinction in a space that remains unmarked, the space from which the observer executes the distinction. The observer must employ a distinction in order to generate the difference between unmarked and marked space, and between himself and what he indicates. The whole point of this distinction (its intention) is to mark something as distinct from something else. At the same time, the observer — in drawing a distinction - makes himself visable to others. He betrays his presence - even if a further distinction is required to distinguish him.
