This talk is based on a book manuscript that Congleton has been working on for several years. The chapter presented, Chapter 2, uses elementary game theory to analyze how internalized ethical dispositions can solve or reduce the severity of various social dilemmas in communities. Insofar as such internalized rules emerge gradually, they provide an evolutionary alternative to the Hobbesian solution. The choice settings examined in the chapter include the one developed by Hobbes, public goods provision, and conventions. Partial solutions to these social dilemmas can make life in communities more attractive, without which as noted by Hobbes, life would tend to be poor brutish and short. However, only a subset of possible ethical systems provide such solutions.
