Monica Ali discusses the UK's use of immigration detention centres and, in particular, indefinite detention.

She argues that, although detention or deportation are sometimes necessary, the policy of indefinite detention is "callous and dehumanising".

She believes - as the only place in Europe that allows indefinite detention - the UK should adopt the recommendations of a recent parliamentary report and introduce a 28 day limit.

"If you're a writer of colour", writes Monica Ali, "you're only supposed to write about what people imagine to be your self".

"That self might be labelled as Asian writer, or Bangladeshi writer or BAME writer, but it is never labelled simply 'writer' - that would be the true privilege".

Val McDermid argues that - at a time when public discourse is so polarised - it's vital to keep our public libraries open.

"A library card is a powerful weapon to change lives", Val writes. "With it, we learn how to value what we have, to mourn what we have lost and to dream of what we might become".

She says that whatever we may hear about the death of libraries, we must ensure their future because they are "one of the few remaining places where a genuine diversity of voices can still be encountered".

David Goodhart argues that recent events show that democracy - far from being in crisis - is actually thriving.

And in the aftermath of Teresa May announcing her resignation, David writes, "I think there is a great political prize for a politician or a party, old or new, that can speak across the liberal/small-c conservative value divide".

Rebecca Stott imagines a conversation with Darwin about our environmental concerns

"While I would love to find a poetic way into this", writes Sarah Dunant, "I think it best just to spit it out. I'm angry. And I have been angry for quite a while now".

Sarah says she doesn't see herself as an angry person - but wonders why aggression and outrage seem to have become so much part of our emotional diet.

She proposes some solutions - including an National Anger Day - a great moment of catharsis to help us all be a little less....angry!

"For many Parisians, it's Notre Dame's constancy that's so reassuring" writes Joanna Robertson. "Pass by before dawn, she’s waiting there. Or late at night, amidst the deserted streets, her dark form is holding steady. Notre Dame was inviolable".

Joanna Robertson reflects on how the fire is changing that taken-for-granted sight.

"If you have ever tried to scan a bio-metric passport, an e-ticket or just a packet of frozen peas", writes AL Kennedy, "you'll know that using technology can turn, within moments, into a bizarre ritual of presenting, rubbing, re-presenting, murmured prayers and computer generated instructions which lead either to complete defeat or the intervention of human assistance that could have been there all along".

She argues that automation must be governed by human needs and strengths.

Personal contact, she believes, is more important than ever.

"There's one thing I can't bear", writes Rebecca Stott, "and that's being talked AT".

Having grown up in a separatist fundamentalist Christian sect called the Exclusive Brethren, she says she's probably rather uniquely sensitised to this. She listened to her father and grandfather holding forth for hours - "3000 hours of male monologues before I was six" she reckons!

Rebecca reflects on the art of good conversation.
