I will try to translate. I'm not a translator, do not judge strictly
According to Marx: "This product, first and foremost, an object outside us, an object, its properties to satisfy certain human needs (Marx, 1867), so the art may well be regarded as a commodity that satisfies human needs. However, Marx contradicts himself, saying, : ... nothing has value, not being the object of utility. If the object is useless, as well as contained in its work; work is not difficult, and therefore does not create any value '(Marx, 1867). Art, except that if the painting closes the hole in the wall, the subject is not useful in practical plan. Therefore, the art and the artist's work is worthless.
