Is there really such a thing as free will? How can humans make genuinely independent choices if we are just a cluster of cells and genes in a world determined by scientific laws? How can we still be in control of our lives?

In this myth-shattering book, Daniel Dennett shows that free will does exist. But instead of the traditional view of freedom as an eternal, unchanging condition of our existence, in reality, he reveals, it has evolved; just like life on the planet and the air we breathe. Evolution is the key to resolving this greatest of philosophical questions – and to understanding our place in the world as uniquely free agents.
