"The effect if not the function of the mass media seems to lie, therefore, in the reproduction of non- transparency through transparency, in the reproduction of non-transparency of effects through transparency of knowledge."

“Unlike philosophy, art does not search for islands of security from which other experiences can be expelled as fantastic or imaginary, or rejected as a world of secondary qualities or enjoyment, of pleasure or common sense. Art radicalizes the difference between the real and the merely possible in order to show through works of its own that even in the realm of possibility there is order after all. Art opposes, to use a Hegelian formulation, “the prose of the world,” but for precisely this reason it needs this contrast.”

“Humans cannot communicate; not even their brains can communicate; not even their conscious minds can communicate. Only communication can communicate.”

“Whatever we know about society, or indeed about the world in which we live, we know through the mass media. This is true not only of our knowledge of society but also of our knowledge of nature.”

“No matter how abstractly formulated are a general theory of systems, a general theory of evolution and a general theory of communication, all three theoretical components are necessary for the specifically sociological theory of society. They are mutually interdependent.”

“In the twentieth century, one encounters artworks that seek to cancel the difference between a real and an imagined reality by presenting themselves in ways that make them indistinguishable from real objects. Should we take this trend as an internal reaction of art against itself?”

“Does knowledge rest on construction in the sense that it only functions because the knowing system is operatively closed, therefore: because it can maintain no operative contact with the outside world; and because it therefore remains dependent, for everything that it constructs, on its own distinction between self-reference and allo-reference?”
