The chapter discusses the issues of identity versus change in the target entity/system phenomenology under the pressure of a societal crisis, in order to ground the crisis’s DRR logic (destabilizing–redesigning–restabilizing). The discussion is based on the concept of entropy—not the concept from Thermodynamics but one that originates in the rapport of heterogeneity/homogeneity, which is a rapport much more specific for the social/economic process. In the context the typology of the change in the Universe is reminded and the issue of identity versus alterity of a generic system is examined. This way are introduced (and combined between the) two logics that characterize the societal crisis topic: (a) DRR logic (destabilizing–redesigning–restabilizing); (b) RRASA logic (robustness–resilience–antifragility–sustainability–autopoieticity). The two logics are examined in their inter-relations under the societal crisis and the conclusions are synthesized based on the processual chain purpose (interest)—role (significance)—function (performance)—hard-core structure (adequacy).
