A second day at the Hay Book Festival. Hazel and I walk around the town, have a coffee, browse (and buy!) second-hand books, she contemplates buying a very ancient-looking and very heavy stone trough for her garden. Impossible to carry.

To be more serious. There was a short item last night from the BBC’s Steve Rosenberg in Russia on a still surviving George Orwell library. They have now been told to find new premises. Free speech and free thinking are dangerous. Ideas are dangerous. Compare Hay. It has no newspaper sponsorship, no political connections. If it’s left of centre, then maybe that’s just because it’s where freethinking takes us.

From the town it’s a ten-minute walk to the festival, just time for lunch, good Indian fare, on paper plates, then our first session, Hazel and I together, Ken Follett and Kate Mosse, two amazing historical novelists, talking. How do they start? He maps out an outline, she launches in, having gone through a total immersion in the period. Her characters speak to her.

We’re in a safe zone, as I am at 2.30, listening to Katherine Rundell being interviewed with her adult (Faber) and children’s (Bloomsbury) editors.  Her book, Super-Infinite, on John Donne, is marvellous, but she is also a hugely popular children’s author, her last being the much-acclaimed Incredible Creatures. She is super-bright and self-assured. She enjoys roof-climbing and tight-rope walking and turns cartwheels before breakfast.

But we lose something of that self-assurance and sure-footedness at 4pm. The subjects are, or should be, challenging. Hazel is off to hear Caitlin Moran talking about men, and feeling sorry for boys who don’t quite know their role any more as women rise higher. My session is a panel taking about ‘The Limits of Comedy’. ‘Play the room’ was the main message from comedy writer Joel Morris. And don’t pitch too low, that is, don’t play too safe. You can only find the limits by playing to them.

The problem – comedy goes viral, it slips out to where it was not intended to go, and offence is caused. For Morris (I’m quoting from an article on the Chortle website, marking the publication of his new book, Be Funny or Die) that is in the very nature of things. ‘Comedy is meant to divide us, and delight us, to appeal to niche audiences … It’s meant to gather us in small tribes under the flag of whatever joke we, and only we, like best.’

5.30 Hazel listens to Channel 4’s international editor, the brilliant Lindsay Hilsum and two other very fine women journalists talking about the Gaza war. I should have been there.

I’ve chosen, as with comedy, something that’s important, but less in the limelight. Sadly, my session, Beyond Conflict: The Role of Libraries, with Elif Shafak and Priscilla Morris, and vice-patron of Book Aid International, Paul Boateng, in the chair, never quite takes off.  Priscilla Morris reads a passage from her novel, Black Butterflies, about the destruction of the National Library in Sarajevo. Ukraine and especially Gaza have seen libraries destroyed. Book Aid is doing a valiant job in Africa. Back home we have school libraries (and in the USA school librarians) threatened. Questions widen the debate but there’s too little on the action we might take. How can we extend the successful focus on literacy (and numeracy) in our schools to a love of reading and literature? And, indeed, history and music? 

History is my subject. If we forget, or learn our history through a distorting lens, we will indeed be condemned to relive it. Hay is part of a long and until recently ever-extending tradition of investigation and understanding and tolerance. The last fifteen years or so have, despite Obama, taken us in another direction. The message must be – yes, we still can.
