We control the world basically because we are the only animals that can cooperate ﬂexibly in very large numbers. And if you examine any large-scale human cooperation, you will always ﬁnd that it is based on some ﬁction like the nation, like money, like human rights. These are all things that do not exist objectively, but they exist only in the stories that we tell and that we spread around. This is something very unique to us, perhaps the most unique feature of our species.
