Andrew Marr on beauty and politics in art. Our idea of beauty was shaped by the great Victorian art critic John Ruskin. He thought all people deserved to see beauty every day, and compared, and founded a gallery in Sheffield for local industrial workers. To mark Ruskin's bicentenary, curator Louise Pullen has put together a new exhibition showing how his ideas about art, science, truth and beauty shaped the politics of the day.

"All art is propaganda and ever must be, despite the wailing of the purists," declared WEB Du Bois. The civil rights campaigner, philosopher and social thinker argued that it was an artist's duty to shape a better world. Academic Liam Bright explains why Du Bois thought both artists and scientists had a duty to tell the truth.

In poet Fiona Benson's new volume Vertigo and Ghost, beauty, violence and power are never far apart. Benson's poems depict Zeus as a serial rapist, and capture the claustrophobia of modern domestic life.

And design guru Stephen Bayley considers what creativity is - and what it is for - in his new book How To Steal Fire. As a leading cultural critic, he asks what place beauty and imagination have in modern life.
