'Life is not a problem to be solved, but a reality to be experienced', wrote the philosopher Soren Kierkegaard. His new biographer, Clare Carlisle, explores the life experiences that moulded Kierkegaard's ideas as he struggled to understand how to be a human being in this world. She tells Amol Rajan that Kierkegaard was very much a philosopher of the heart.

DeRay Mckesson’s reality became one of struggle and action after he quit his job as a school teacher and became a key figure in the Black Lives Matter movement in the US. He spent 400 days on the streets of Ferguson, Missouri, often walking day and night after a new law was introduced making it illegal to stand still. In his memoir, On the Other Side of Freedom, he explores the intellectual and political framework of the liberation movement that has dominated American life in the 21st century.

The award-winning poet and playwright Inua Ellams’s latest work also explores freedom and power, but in a world where fate and vengeful gods hold sway. His epic poem The Half-God of Rainfall begins with a game of basketball in Nigeria with the Yoruba gods looking on, and ends with a demonstration of female revenge – both human and mythological.

While Kierkegaard was focused on the subjective experience of being a human, and how we create ourselves through our action, the writer Elizabeth Day is interested in what happens when those actions go awry. ‘How To Fail’ is a painfully honest exploration of things going wrong, and what we can learn from our mistakes.

We underestimate how difficult it is to live in remote areas, says travel writer Dan Richards. He tells Kirsty Wark how he trekked to high mountain huts and distant snowy cabins for his new book, Outposts. Richards followed in the footsteps of Virginia Woolf, Roald Dahl and Jack Kerouac, who all found inspiration in the wilderness. But just as Kerouac went temporarily mad living on a remote mountainside, so today’s tourists in the Scottish Highlands and Nordic isles underestimate “hard nature’s indifference”.

Icelandic model turned sheep farmer Heida Asgeirsdottir knows how challenging countryside life can be. After an early career as a model in New York, she returned to Iceland to take over her parents’ sheep farm in a region of volcanoes and elemental storms. But even this distant region needs modern power and infrastructure, and this means a new hydro-electric plant whose owners want to flood her farm.

A family feel stuck in the middle of nowhere in Chekhov’s searing play Three Sisters. Rebecca Frecknall is directing a new production at the Almeida Theatre, exploring the thwarted ambitions and dreams of a provincial Russian town. Sisters Irina, Olga and Masha long to return to Moscow, but become bogged down in dead-end jobs and trapped by mortgages and marriage.

Chekhov’s play could easily be set in a British town today, says Sarah O’Connor from the Financial Times. She looks at the stark problems facing our seaside resorts and post-industrial towns. In her Orwell Prize-winning study of Blackpool, she challenged the idea that our seaside towns lack aspiration and are destined to fail. Now she explains why terms like “the Left Behinds” are dangerously misleading.

Ian McEwan talks to Andrew Marr about his new novel, Machines Like Us, and reflects, at the age of 70, on a career which began more than four decades ago.

Machines Like Us is set in an alternative Britain in the 1980s, Margaret Thatcher has lost the Falklands war and the scientist Alan Turing has made a breakthrough in artificial intelligence leading to a series of synthetic humans. The love-triangle at the heart of the book forces the reader to confront ideas about what makes us human and what happens when we lose control of our creations.

Ian McEwan published his first book, a collection of short stories called First Love, Last Rites, in 1975. It won critical acclaim, as well as comment about the sometimes shocking subject matter. Since then, he has published 15 novels, and won the Man Booker Prize in 1998. He is a literary writer who has also enjoyed great popular success, with his novel Atonement selling well over a million copies in the UK alone.

850,000 people in the UK are thought to be living with dementia. The writer Nicci Gerrard tells Andrew Marr about her father’s slow death from the illness. She explores issues around memory, language and identity, as well as asking how society will cope as the population ages and the number of people suffering with dementia rises into the millions.

But why and how do we age? The science journalist Sue Armstrong has been investigating what happens to cells when the body gets older, and whether ageing really can be treated like any other disease waiting to be cured. Life expectancy has risen sharply in the last half century globally, but can it keep on rising?

The street theatre performance, Bed, involving elderly actors lying in beds in town centres around the country, was devised by older members of Entelechy Arts who wanted to make a statement about isolation and invisibility. The Artistic Director David Slater says the arts have an important role to play in improving people’s lives no matter how old.

The poet John Agard is 70 this year. In his latest collection, The Coming of the Little Green Man, he explores the world from the stance of the outsider. In a series of mischievous, satirical fables he gives voice to the political and spiritual, comic and poignant.
