YORK will again be seeking to open the eyes of the world to things which can change the future when it hosts the city’s fourth Festival of Ideas.

More than 140 events will be taking place across the York University campus and the city – aiming to raise eyebrows and challenge established thinking.

Taking place on the centenary of the outbreak of the Great War this year’s official theme is Order and Chaos.

But when it comes to debate, no stone will be left unturned with speakers from the arts, science, politics, literature, history and medicine.

Most of the events taking place from June 12 to 22 are free – and intended to reach far beyond academic circles to the widest possible audience.

The line-up includes War Horse author Michael Morpurgo in conversation in a free event at York Theatre Royal.

Talks by crime writers include Anthony Horowitz revealing some of the secrets of his new Bond novel.

A keynote debate will face up to the challenge of feeding a world population of ten billion.

But there will be plenty of fun as well with festival goers getting the chance to try ale based on an authentic Ango Saxon recipe.
