Vincent Hendricks (Copenhagen/Columbia) gives a talk at the Workshop on Mathematical Philosophy titled "IPAD – Information Processing and the Analysis of Democracy". Abstract: Only one species have configured a democracy and decided to live according to deliberative democratic guidelines. The configuration and decision is particular to man. A deliberative democracy is characterized by both group deliberation, decision and action. Central to this epistemic composite is information as information processing is an essential fabric of rational deliberation, decision and action which in turn amount to the rational interaction among members of a group or a democracy. Thus, a robust deliberative democracy is the quintessential example of rational agent interaction. This intimate connection fuels a new research paradigm in interdisciplinary philosophy: IPAD -- Information Processing and the Analysis of Democracy.
