Dennett shows that human freedom is not an illusion; it is an objective phenomenon, distinct from all other biological conditions and found in only one species - us. There was a time on this planet when it didn't exist, quite recently in fact. It had to evolve like every other feature of the biosphere, and it continues to evolve today.



Dennett shows that far from there being an incompatibility between contemporary science and the traditional vision of freedom and morality, it is only recently that science has advanced to the point where we can see how we came to have our unique kind of freedom.
