A remarkable culmination of a lifetime's research into the way the brain works by the celebrated late neurologist Oliver Sacks.

Two weeks before his death, Oliver Sacks outlined the contents of The River of Consciousness, the last book he would oversee. The bestselling author of On the Move, Musicophilia, and The Man Who Mistook His Wife for a Hat, Sacks is known for his illuminating case histories about people living with neurological conditions at the far borderlands of human experience.

But his grasp of science was not restricted to neuroscience or medicine; he was fascinated by the issues, ideas and questions of all the sciences. That wide-ranging expertise and passion informs the perspective of this book, in which he interrogates the nature not only of human experience but of all life.

In The River of Consciousness, Dr. Sacks takes on evolution, botany, chemistry, medicine, neuroscience and the arts, and calls upon his great scientific and creative heroes above all, Darwin, Freud and William James. For Sacks, these thinkers were constant companions from an early age; the questions they explored – the meaning of evolution, the roots of creativity and the nature of consciousness lie at the heart of science and of this book.

The River of Consciousness demonstrates Sacks’s unparalleled ability to make unexpected connections, his sheer joy in knowledge and his unceasing, timeless endeavour to understand what makes us human.

‘Sacks writes, basically, adventure stories, accounts of voyages into the unexplained territory of the brain. In doing so, he reveals a landscape far more complex and strange than anything we could infer from our daily interactions’ Sunday Times
