From Herbert Marcuse’s One-Dimensional Man, pp. 61-62:
“The tension between the actual and the possible is transfigured into an insoluble conflict, in which reconciliation is by grace of the oeuvre as form: beauty as the “promesse de bonheur.” In the form of the oeuvre, the actual circumstances are placed in another dimension where the given reality shows itself as that which it is. Thus it tells the truth about itself; its language ceases to be that of deception, ignorance, and submission. Fiction calls the facts by their name and their reign collapses; fiction subverts everyday experience and shows it to be mutilated and false. But art has this magic power only as the power of negation. It can speak its own language only as long as the images are alive which refuse and refute the established order.
