 In his 2000 Dimbleby lecture, "Who's afraid of modern art", Sir Nicholas Serota advocated such kinds of "difficult" art, while quoting opposition such as the "Daily Mail" headline "For 1,000 years art has been one of our great civilising forces.Today, pickled sheep and soiled beds threaten to make barbarians of us all".A more unexpected rejection in 1999 came from artists—some of whom had previously worked with found objects—who founded the Stuckists group and issued a manifesto denouncing such work in favour of a return to painting with the statement "Ready-made art is a polemic of materialism".
