Social Practices

We simulate systems of social practices based on BDI ("believe - desire - intention") systems. The PROLOG programmes generate and handle systems of beliefs and intentions of actors by 'empirical' rules which are not valid in all cases. The beliefs and intentions are represented by action-types. Sets of action types and the appertaining believes and intentions characterise groups of actors. The simulations show how some groups are stabilized by their beliefs and belief changes.

Elementary actions can be represented with verbs in a natural language. For each joint action we can construct a social practice. These practices are the building blocks in our social simulations. Our account avoids real numbers and real functions to express actions. We represent actions and action-types by verbs.
