I was cleaning a room and, meandering about, approached the divan and couldn’t remember whether or not I had dusted it. Since these movements are habitual and unconscious, I could not remember and felt that it was impossible to remember – so that if I had dusted it and forgot – that is, had acted unconsciously, then it was the same as if I had not. If some conscious person had been watching, then the fact could be established. If, however, no one was looking, or looking on unconsciously, if the whole complex lives of many people go on unconsciously, then such lives are as if they had never been.
And then Shklovsky writes:
And so life is reckoned as nothing. Habitualization devours works, clothes, furniture, the fear of war. "If the whole complex lives of many people go on unconsciously, then such lives are as if they had never been." And art exists that one may recover the sensation of life; it exists to make one feel things, to make the stone stony. The purpose of art is to impart the sensation of things as they are perceived and not as they are known. The technique of art is to make objects "unfamiliar", to make forms difficult, to increase the difficulty and length of perception because the process of perception is an aesthetic end in itself and must be prolonged.
