Law, Contract, and Power

The development of computer networks is affecting various aspects of society, both nationally and internationally. In such an age, the rules for the formation of social structure should be reviewed radically; for example, how can the aggregation of egocentric actions by individuals generate macro social structures from a chaotic state? Although this has long been a common theme in sociology and its importance is now increasing because of the ecological implications, up to now no clear theoretical answer has been established. In this paper, I present some models to solve this problem. The models have the following features: in the initial state, there is no given social consciousness because of the original nature of human beings. There are no given laws, ethics, morality, and so on. Each individual does not have complete information about the whole world, and there is uncertainty about the natural world. Each individual produces some kinds of goods necessary for his life and acts for self-preservation on rules set by the individual based on his experiences and limited observations. Depending on the results, the rules can be changed to interact with others. The models showed that repetition of interactions among individuals resulted in formation of certain recognizable patterns which could be interpreted as formation of natural law, power, and social structure. Based on these findings, I believe that the models offer some insights into social change and social relationships.
