3. Mental Mazes

Charlotte Higgins investigates some mental mazes, and Sigmund Freud's view that psychoanalysis "supplies the thread that leads a man out of the labyrinth of his own unconscious."

She also describes the neuroscience behind the human being's sense of direction, the enlarged hippocampi of London cabbies, and how, on some level, "finding our way through life, building up stories about ourselves and making meaningful memories out of our experiences, may be twined together with our ability to navigate..."

Series exploring more of our ancient fascination with mazes and labyrinths, and reflects on their significance - in art and in mythology, in literature and in life.

Written and read by Charlotte Higgins.

Abridged and produced by David Jackson Young.

First broadcast on BBC Radio 4 in August 2018.
