14 The Darwinian revolution is both a scientific and a philosophical revolution, and neither revolution could have occurred without the other… If I were to give an award for the single best idea anyone has ever had, I’d give it to Darwin, ahead of Newton and Einstein and everyone else. In a single stroke, the idea of evolution by natural selection unifies the realm of life, meaning, purpose, with the realm of space and time, cause and effect, mechanism and physical law. DC Dennett Darwin’s dangerous idea: evolution and the meanings of life
