This book presents an elementary but complete exposition of the relativistic theory of the measurement of intervals in space & time.

There has been a persistent tendency to identify what is called “the freerider problem” in the production of collective goods with the prisoner's dilemma. However, in this article I want to challenge that identification by presenting an analysis of what are in fact a variety of collective action problems in the production of collective goods. My strategy is not to consult any intuitions about what the free-rider problem is; rather I will be looking at the problematic game-theoretic structures of various (...) situations associated with the production of different types of collective goods, thereby showing what sorts of difficulties a community concerned with their voluntary production would face. I call all of these dilemmas free-rider problems because in all of them certain individuals find it rational to take advantage of others' willingness to contribute to the good in a way that threatens its production. Some readers may feel that the term ‘free-rider problem’ is so identified with the prisoner's dilemma that my extension of the term in this way “jars”; if so, I invite them to coin another word for the larger phenomenon. My aim is not to engage in linguistic analysis but to attempt at least a partial analysis of the complicated structure of collective good production. (shrink)

This book explores the role of artificial intelligence in the development of a claim that morality is person-made and rational. Professor Danielson builds moral robots that do better than amoral competitors in a tournament of games like the Prisoners Dilemma and Chicken. The book thus engages in current controversies over the adequacy of the received theory of rational choice. It sides with Gauthier and McClennan, who extend the devices of rational choice to include moral constraint. Artificial Morality goes further, by (...) promoting communication, testing and copying of principles and by stressing empirical tests. (shrink)
