A different recent take on "where is X really located?" is The Secret of Our Success by Joseph Henrich, which argues that our useful intelligence is largely in our culture and our capacity to build it incrementally, rather than in our individual minds' capacities. He starts off with observations about well-educated, intelligent, capable people in possession of sophisticated technology starving or freezing to death when they were stranded in unfamiliar physical environments, in which other cultural groups could thrive. If Turner thinks that your constructed habitat is part of your body, Henrich thinks that your culture is part of your intelligence, and for a wide range of purposes, the most important part.
