Social Order becomes a major problem in MAS and in computer mediated human interaction. After explaining the notions of Social Order and Social Control, I claim that there are multiple and complementary approaches to Social Order and to its engineering: all of them must be exploited. In computer science one try to solve this problem by rigid formalisation and rules, constraining infrastructures, security devices, etc. I think that a more socially oriented approach is also needed. My point is that Social Control - and in particular decentralised and autonomous Social Control - will be one of the most effective approaches. 0. The framework: Social Order Vs Social Control This is an introductory paper. I mean that I will not propose any solution to the problem of social order in engineering cybersocieties: neither theoretical solutions and even less practical solutions. I want just to contribute to circumscribe and clarify the problem, identify relevant issues and discuss some notions for...
