Dresser was a one-of-a-kind designer in the nineteenth century. He is regarded as a forerunner of modern industrial design, creating simple, practical things for mass production when colleagues like William Morris and John Ruskin advocated a return to craft production based on the mediaeval guild model.
Aestheticism describes the European art movement of the late 19th century. It is centred on the doctrine that art exists alone for the sake of its beauty and that it does not have to serve any political, didactic or another purpose.
Aestheticism is diametrically opposite to the moralist belief, the belief that moralism (and everything else) should be the handmaiden of art instead of art (and everything else) being the handmaiden of morality.
