York will be fizzing with ideas again in June, when the Festival of Ideas returns for its fourth year. Tickets are available from today. STEPHEN LEWIS reports

HOW should we respond to the crisis in Ukraine? Will we be able to feed the world as the population grows towards nine billion? Do religion and science really need to be at war with each other? What is the future of banking? And should we be in or out of the Eurozone?

Just some of the questions that will be debated at this year's York Festival of Ideas, which runs from June 12 to 22.

To mark the fact that 2014 is the100th anniversary of the start of the First World War, the festival's theme this year is 'order and chaos'.

But that leaves plenty of scope. Arts, science, politics, literature, history and medicine will collide in more than 140 events being held at venues across the city.

War Horse author Michael Morpurgo will be in conversation in a free event at York Theatre Royal; Ann Frank's step-sister Eva Schloss will talk about surviving Auschwitz; there will be a debate about how northern cities can better compete with the giant 'city state' that is 21st-century London; and chemist Dave Smith will reveal the hidden science behind your cream tea – in an event being held at Bettys, of course.

Anthony Horowitz will talk about his new Bond novel during a series of events and talks involving crime writers. And, as part of a theme focusing on York's Anglian past, festival-goers will even have the chance to sample some genuine Anglo-Saxon ale – or at least, a new brew made to an authentic Anglo-Saxon recipe.

The festival officially opens on the evening of Thursday June 12 with a keynote debate – The Crossroads of Conflict – about how we should best respond to global crises such as the tension in Ukraine, the civil war in Syria and the abduction of hundreds of schoolgirls in Nigeria.

This, the launch event, will see Sir Roger Dalton – Britain's first Ambassador to Libya after the lifting of sanctions – talking about whether the international response to such situations is working.

James Rubin, a former US Assistant Secretary of State in the Clinton years, will then discuss the United States's role in peace keeping, before a panel discussion involving the likes of the BBC's chief international correspondent Lyse Doucet.

At least, Doucet is hoping to be here, says festival director Joan Concannon. Whether she makes it may depend on whether she is called upon to report on yet another international crisis. "But she's very keen to come."

As usual, this year's festival – the fourth – will be a mix of science, politics, history and other disciplines: mixing things up creates sparks and 'new dimensions', says Joan. And as usual, it is for everyone.

Most events are free (although you will need to book tickets, because places are limited), and they will be held at venues across the city: from the Acomb Explore Library, the Theatre Royal, Bettys and St Helen's Church to the National Centre for Early Music, St Peter's School, the Merchant Adventurer's Hall and the University of York, which organises the festival.

You don't need any specialist knowledge to attend any of the events, Joan stresses. "Just an enquiring mind."

The festival is rapidly becoming a highlight of York's cultural calender, says Joan, as well as being yet another reason for visitors to come to York.

"We believe that (it) embodies the adventurous spirit of the City of York - a city that has always been open to new ideas," she says.

Tickets for all 140-plus events - most of which are free - are available from today. So go on, check out the festival brochure online, and make sure you don't miss out...
