Audiences of the movie Avatar are asked to accept that, by means of a vaguely-described technology, Jake Sully’s mind is transferred into the body of a blue-skinned, nine-foot native of the moon Pandora. And they do accept it, with ease – even I, who consider myself attuned to issues of personal identity, bought the story without thinking about its strangeness until later.

It wouldn’t be the same book.”
