Abstract
The post-Westphalian Nation State developed by becoming more and more an Information Society. However, in so doing, it progressively made itself less and less the main information agent, because one of the main forces that made the Nation State possible and then predominant, as a historical driving force in human politics, namely Information and Communication Technologies (ICTs), is also what is now making it less central, in the social, political and economic life of humanity across the world. ICTs enable and promote the agile, temporary and timely aggregation, disaggregation and re-aggregation of distributed groups around shared interests across old, rigid boundaries represented by social classes, political parties, ethnicity, language barriers, physical and geographical barriers, and so forth. Similar novelties call for a serious exercise in conceptual re-engineering. This paper argues for the need to understand how the new informational multiagent systems may be designed in such a way as to take full advantage of the socio-political progress made so far, while being able to deal successfully with the new global challenges (from the environment to the financial markets) that are undermining the legacy of that very progress.
