Gormley: Art is an open space for generating "alternative value."

Asking "What is art for?," Antony Gormely comes up with "some propositions":

• Politics has become management.

• Ideological positions are unsustainable when comfort is the highest good.

• We are post-ideology.

• Art is an open space that allows for the generation of alternative value.

Gormley just opened his first major London show at the Hayward Gallery. A key work in Blind Light is a chamber filled with dense vapor created by oscillating ultrasonic humidifiers that reduce visibility.
