Ostranenie
Art as defamiliarization; making familiar perceptions seem strange.
On the cultural level, it is difficult to make progress in a world that is constantly being familiarized. Ostranenie is a vital function of art, for it breaks us out of our normal ways of seeing and thinking and creates the possibility of seeing and thinking in new ways.
