‘Could a machine ever be said to have made its own decisions? Could a machine have beliefs? Could a machine make mistakes? Could a machine believe it made its own decisions? Could a machine erroneously attribute free will to itself? Could a machine come up with ideas that had not been programmed into it in advance? Could creativity emerge from a set of fixed rules? Are we - even the most creative among us - but passive slaves to the laws of physics that govern our neurons?’

From the foreword by Douglas Hofstadter for ‘The Enigma’ by Andrew Hodges
