PREVIEW: How The Light Gets In Festival Gets Ready For Year 6 - With Theme Of 'Heresy, Truth And The Future'

How The Light Gets In, the world's largest philosophy and music festival, is gearing up for its sixth annual gathering, to take place in Hay-on-Wye at the end of May.

Guest speakers at the event include comedian Marcus Brigstoke, filmmaker Julien Temple, broadcaster Dame Joan Bakewell, actress Imogen Stubbs and French philosopher Bernard-Henri Lévy, as well as former Chancellor Norman Lamont and Wikileaks chief spokesperson Kristin Hrafnsson.

Debates will take place under one of the festival's many venues

The theme of this year's festival is Heresy, Truth and the Future, inspiring 450 events over ten days. Highlights include:

Independence Day (22 May)

With the future of Scotland and Catalonia hanging in the balance, Channel 4 political correspondent Michael Crick asks former ambassador to the US John Kerr, historian Count Nikolai Tolskoy, and Liberal Democrat politician Diana Wallis to debate the future of the nation state.

Bang Goes the Big Bang (24 May)

Theoretical physicists Roger Penrose. multiverse cosmologist Laura Mersini-Houghton, and CERN particle theorist John Ellis go back to the beginining.

Who's Afraid of the Truth: Bernard-Henri Lévy in conversation with Rana Mitter (24 May)

France's most public intellectual Bernard-Henri Lévy turns his sights on the hypocrisy and blindness of politicians and philosophers alike.

Known for fierce opposition to totalitarianism in all its forms, BHL personally persuaded Sarkozy to intervene in Libya and is a radical force in France's cultural life.

*After Equality (24 May)

Equality is usually seen as the goal of feminism. Yet with women more than a third more likely to go to university than men, and with more female entrants to medicine and law, does this limit the horizon? Rather than equality should we be championing difference? Or is this a dangerous heresy that threatens progress?

Huffington Post UK editor Carla Buzasi hosts Times columnist David Aaronovitch, writer and broadcaster Beatrix Campbell, and feminist journalist Julie Bindel as they look beyond equality.
