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.
