Free Thinking: Artes Mundi Prize. Harriet Walter. Amitav Ghosh. Edmund Richardson

Artes Mundi was established in 2003 as a biennial contemporary visual arts initiative - the poet, author and playwright Owen Sheers and Catherine Fletcher, historian and New Generation Thinker, report back on the exhibition opening in Cardiff this week with work by the chosen artists including Britain's John Akomfrah, Nástio Mosquito and Bedwyr Williams.

Amitav Ghosh argues that fiction writers need to be bolder in tackling the big themes of today's world and why thinking about Climate Change is proving a challenge.

Harriet Walter has played Brutus and the King in Phyllida Lloyd's all-female Shakespeare productions of Shakespeare's Julius Caesar and Henry IV; now she takes on Prospero in The Tempest. She talks to Anne McElvoy about giving herself permission to take on roles still normally given to men and the never-ending wonder of Shakespearian verse as the entire trilogy opens in London.

Plus - ahead of the American Presidential election, New Generation Thinker and historian, Ed Richardson pops up with the mesmerising story of how Hillary Clinton is very far from being the first ever female Presidential candidate.
