She dedicated her books to ‘her husband’ and wrote of 'this double life, which helps me to feel and think with double strength'. The philosopher and writer Clare Carlisle has written a new biography of George Eliot which places The Marriage Question at the centre of her art and life.

It’s twenty years since the US and UK invaded Iraq to overthrow Saddam Hussein. Kirsty Wark discusses the lead up to the war, the impact on the lives of Iraqis and the legacy.

Ghaith Abdul-Ahad left his job in Baghdad and became a journalist during the Iraq War in 2003. He witnessed first-hand the liberation of his country from a megalomaniac leader and then its descent into factionalism and violence. In A Stranger In Your Own City he movingly recounts the very real human cost of the invasion, as well as the civil wars and rise of ISIS that followed.

Emma Sky volunteered to help rebuild Iraq post-invasion and went on to serve as the representative of the Coalition Provisional Authority in Kirkuk and then as a political advisor to the US army in the following decade. Now an academic at Yale University, she looks back at why the Iraq invasion failed and its implications across the region. She's the author of The Unravelling and In a Time of Monsters: Travelling in a Middle East in Revolt.

The BBC’s Security correspondent Gordon Corera was a young reporter during the frenetic build up to the war, talking to spies, defectors and politicians. In a 10-part series – Shock and War: Iraq 20 Years On (from 13th March at 1.45 and on BBC Sounds) – he talks to those at the centre of that decision to go to war, and looks at the far-reaching consequences, from trust in politics, security and liberal intervention.

It’s Ok To Be Angry About Capitalism is the title of the new book by the US politician Bernie Sanders. In it he castigates a system that he argues is fuelled by uncontrolled greed and rigged against ordinary people. He tells Tom Sutcliffe it’s time to reject an economic order and a political system that continues to benefit the super-rich, and fight for a democracy that recognises that economic rights are human rights.

The Chief Economics Commentator at the Financial Times Martin Wolf looks more closely at how and why the relationship between capitalism and democracy appears to be unravelling. But despite the failings – slowing growth, growing inequality and widespread popular disillusion – he argues in The Crisis of Democratic Capitalism that the relationship remains the best system for human flourishing.

But the economist Kate Raworth believes that mainstream economics has had its day. Its failure to predict and prevent financial crises, while allowing extreme poverty, inequality and environment degradation to persist, means its contributing to, not solving, societal unrest. She argues that her theory – Doughnut Economics – offers a new model for a green, fair and thriving global economy.

The theoretical physicist Carlo Rovelli celebrates the life of an ancient Greek philosopher, in Anaximander And The Nature Of Science (translated by Marion Lignana Rosenberg). He tells Adam Rutherford that this little known figure spearheaded the first great scientific revolution and understood that progress is made by the endless search for knowledge. Anaximander challenged conventions by proposing that the Earth floats in space, animals evolve and storms are natural, not supernatural.

The travel writer Kapka Kassabova has gone searching for ancient knowledge about the natural world in her latest book, Elixir: In the Valley at the End of Time. The Mesta River, in her native Bulgaria, is one of the oldest inhabited rivers in Europe, and a mecca for wild plant gatherers, healers and mystics.

In Dvořák’s lyric opera the eponymous hero Rusalka is a water spirit who sacrifices her voice and leaves her home for the love of a Prince. In a new contemporary staging at the Royal Opera House (21 February–7 March 2023) the co-directors Ann Yee and Natalie Abrahami foreground the uneasy relationship between nature and humanity, and the latter's destruction of what it fails to heed.

The psychologist Kimberley Wilson lays bear the truism ‘we are what we eat’. In Unprocessed: How the Food We Eat is Fuelling our Mental Health Crisis she bring into sharp focus the known links between diet, brain, behaviour and mental health. She tells Tom Sutcliffe how the government’s failure to address poor nutrition is a catastrophe.

Rebecca O’Connell’s research focuses on the social, cultural and economic reasons that shape what children and families eat, and the part food plays in their everyday lives. With the cost of living crisis and an increase in families suffering food poverty, she looks at the capacity to ‘choose’ to buy healthier food, and what other countries, like Portugal, have achieved in prioritising school meals.

But what about the food itself and how it’s grown? The author of The Ethical Carnivore, Louise Gray, turns her attention to fruit and veg in her latest book, Avocado Anxiety And Other Stories About Where Your Food Comes From. Tracking from farm to table, Gray discovers the impact that growing fruits and vegetables has on the planet.

Shakespeare’s Lady Macbeth is ruthless in her pursuit of power and then driven into madness and despair. But the writer and director Zinnie Harris has re-imagined a new story for Lady Macbeth in her version of this classic play. Macbeth (an undoing) - published by Faber - is on at The Lyceum Theatre in Edinburgh until 25th February.

Marion Gibson is Professor of Renaissance and Magical Literatures at the University of Exeter and is interested in how power and superstition collide in witch-trials through the centuries. In her latest book, The Witches of St Osyth, she tells the story of the sixteen women and one man accused of sorcery in a small rural village in 1582, and of a community devastated by violence and betrayal.

The filmmaker Jo Ingabire Moys draws from her own experience of surviving the Genocide in Rwanda in her short film Bazigaga, shortlisted for a BAFTA. As violence erupts a Tutsi pastor and his young daughter take shelter in the home of the feared shaman Bazigaga. The film was inspired by the true story of Zura Karuhimbi who used her reputation as a witch doctor to save hundreds of lives.
