 The idea of dignifying commonplace objects in this way was originally a shocking challenge to the accepted distinction between what was considered "art" as opposed to "not art".Although it may now be accepted in the art world as a viable practice, it continues to arouse questioning, as with the Tate Gallery's Turner Prize exhibition of Tracey Emin's "My Bed", which consisted literally of a transposition of her unmade and disheveled bed, surrounded by shed clothing and other bedroom detritus, directly from her bedroom to the Tate.In this sense the artist gives the audience time and a stage to contemplate an object.
