This major study of Hobbes's political philosophy draws on recent developments in game and decision theory to explore whether the thrust of the argument in Leviathan, that it is in the interests of the people to create a ruler with absolute power, can be shown to be cogent. Professor Hampton has written a book of vital importance to political philosophers, political and social scientists, and intellectual historians.

Such theories unsuccessfully attempt to accommodate an internalist intuition (that one's good depends in some way on one's desires or hypothetical desire) with a rationalist intuition (that only fully-informed desires are relevant to one's good).
