Defamiliarization
Art exists so we may recover the sensation of life as it is seen, perceived, not as it is known. The artist must increase the difficulty and length of the experience of perception. The role of art is to defamiliarize: to make things seem unfamiliar rather than automatic; to make us see things as if we were seeing them for the first time.

Viktor Shklovsky, Russian Formalist movement in the early 1920s.
