In the first of four lectures, recorded in front of an audience at Tate Modern in London in 2013, the artist Grayson Perry reflects on the idea of quality and examines who and what defines what we see and value as art. He argues that there is no empirical way to judge quality in art. Instead the validation of quality rests in the hands of a tightknit group of people at the heart of the art world including curators, dealers, collectors and critics who decide in the end what ends up in galleries and museums. Often the last to have a say are the public.
