“If you want to co-operate in a group to solve a large problem, you need some amount of hierarchy, just so you know who is the expert on which subject. It really doesn't matter if the subject is computer support, roving the rivets in lapstrake ship planking, or washing the wort kettle; the point is that division of labour implies specialization implies hierarchy, because once you have specialization you have specialization in keeping track of things, and thus taxonomies, and telling a taxonomy from a hierarchy in the presence of a determined will to keep them separate requires good light and some squinting.”
