Tom Sutcliffe discusses free will and fate; dreams and reality. Jesmyn Ward's prize-winning novel Sing, Unburied, Sing, set in the American South, is haunted by the ghosts of the past. Ward writes of incarceration and freedom, and the strength - and weakness - of family bonds.

For his latest ballet, choreographer Kim Brandstrup has taken inspiration from Calderon's 17th century Spanish play Life is a Dream, in which a dire prophecy leads a King to imprison his son. Brandstrup uses contemporary dance to explore where dreams end and reality begins, but also to express wonder at life itself.

How to live well is at the centre of Edith Hall's self-help book based on the teachings of Aristotle. She examines the ancient Greek philosopher's ideas on how self-knowledge, responsibility and love could help us forge a more meaningful life.

And the philosopher John Gray continues his exploration of what it is to be human in his new work, Seven Types of Atheism.

Fifty years after radicals took to the streets of Paris and stormed campuses across the Western World, Andrew Marr unpicks the legacy of 1968.

Historian Richard Vinen finds waves of protest across the western world in his book The Long '68: Radical Protest and Its Enemies. Some movements were genuinely revolutionary, such as the ten million French workers whose strike nearly toppled the government. But on American university campuses and in British art schools, protests took the forms of civil rights marches and feminist collectives, whose narratives changed the way we think today.

In Paris, left-wing students armed with works of philosophy took on the police and the state. But Paris was still coming to terms with its Nazi occupation, explains Agnès Poirier. Her new book follows the artists and writers of the 40s and 50s, from Simone de Beauvoir and Jean-Paul Sartre to Miles Davis and James Baldwin, as a new generation helped France regain its reputation for art, passion and political action.

Not only left-wing radicals were inspired by the events of that year. In 1968 philosopher Roger Scruton was holed up in a Paris bedroom studying while rioters smashed windows outside. Scruton was horrified by the chaos and destruction, and turned his back on the left-wing politics of his childhood. He became part of a generation of new conservatives who sought to preserve the past rather than fight for an unknown future.

Today France is facing new waves of strikes, with railway workers bringing the transport system to a halt and Emmanuel Macron pushing through sweeping reforms to social security. Sophie Pedder, Paris bureau chief for The Economist and author or a new biography of Macron, asks what France in 2018 owes to the events of 1968.

Facebook co-founder Chris Hughes makes a case for cash handouts to the poor. He tells Andrew Marr that having become exceptionally wealthy he is looking for the most efficient way to give something back to society, and a Universal Basic Income is among his ideas.

But the Oxford academic Ian Goldin argues that UBI is an intellectual sticking plaster. He suggests targeted benefits, better taxation and philanthropy may be the answers to today's growing inequality and the prospect of mass job losses due to automation.

Caroline Slocock was the first female Private Secretary at No.10, employed by Prime Minister Margaret Thatcher. She looks back at the last years of Thatcher's time in office, and Thatcher's vision of a smaller state and individual responsibility.

Margaret Thatcher used the parable of the Good Samaritan to argue her case, suggesting that the voluntary actions of a wealthy Samaritan trumped the collective action of the state. Nick Spencer, Research Director at the public theology think tank Theos, explores how this parable has been hijacked for political ends from both the left and the right.

Amol Rajan discusses faith and doubt. Religion is a recurrent theme in Naomi Alderman's novels. Her first book, Disobedience, explored a Jewish girl's split with orthodox religion, while in Liar's Gospel she told multiple stories of Jesus through the eyes of those around him.

Obedience was a virtue for the nuns of sixteenth-century Italy, but the music they wrote and sang was far less virtuous. Music professor and performer Laurie Stras has unearthed sensual and experimental works by nuns including the daughter of Lucrezia Borgia. And while many flocked to the nunneries to hear these women perform, others accused them of irreligious vanity.

Historian and Anglican priest Malcolm Guite tells the life of Samuel Taylor Coleridge and finds religious imagery permeating Coleridge's most famous work, The Rime of the Ancient Mariner.

And the writer and former Bishop of Edinburgh, Richard Holloway, asks how spiritual belief can help us face our mortality, in his new book Waiting for the Last Bus.
