Marcel Duchamp was perhaps the most salient example, if not the originator, of this te ndency. For the individual interested in culture, the artist's constant removal of the ground from under one's feet is disconcerting. The work of art and the method of forming judgements resolutely resist being pinned down. Now, culture is a good deal more knowable than art. For a start, the language of culture is familiar as the language of everyday discourse, given the addition of a few jargon words and key concepts.
Culture can embrace politics, daily life, socioeconomics, all the disciplines of reality.
In short, culture means something, whereas the best that can be said about art is that it is not sure what it means. The phenomenon of political correctness is something of a joke nowadays, but the re-writing of curriculums, pa rticularly in literature, to encourage the idea that all forms of cultural artefacts are worthy of serious study has had a profound and in many cases beneficial impact. So, for the bewildered person of culture, the business of judging art becomes considerably easier. Each piece of music, writing, painting, sculpture, pottery, bandes dessin es, CD-ROM, etc. etc. These cultural artefacts have properties that are different, to be sure, but in terms of worth they are equivalent.
