We will discuss not only how individual decisions lead to aggregates (e.g. social structures) but also how the aggregates determine the behavior of the individuals. The feedback from the macro scale to the micro scale occurs both with respect to what is actually done, and, via evolution, also with respect to the behavioral `rules.' Moreover we will discuss behavioral rules of the aggregates as response to environmental clues which can not be perceived at the microscale.
