Civilizing Cooperation: Paul Seabright and the Company of Strangers

Paul Seabright is the first to clearly identify a major puzzle about human social evolution: the expansion of cooperation in the more complex societies of the Holocene. Identifying that problem is a major achievement, but in this paper I give a somewhat different account of the nature of the problem and a somewhat different account of the social world of Pleistocene foragers. So, we agree that there is a problem, but not on its nature or solution.
