Abstract
How can the society be formed? This is the most radical question Simmel had asked, and we also would ask.
In this paper, we present some preparatory models for the great question above.
Our first model explains the generation of pre-society, social circle, only by repetition of our most elementary social interactions, exchanges of goods.
Then, we introduce “death” and “stock of goods” in the model.
These models are written as computer programs. So, the dynamism of generation and changes of social circles are visualized, and can be simulated on various conditions.
We got some interesting results from them, and they are the first steps of our further researches.
