The modern European concept of social contract as the classical normative measure, the ontology of agreement at the level of meaning, requires an original non-linear presentation to obtain its practical capacity in the XXI century. It is this criterion that is proposed in the dissertation as the basic one, which contributes to the objective socio-philosophical analysis of the current global transformations inherent in autoreflexive societies of high complexity levels. The author advocates the idea that presentation of the modern social contract has a priori controversial background, since this is primarily about the historical criteria of the project, the progress of which is possible only through shifting semantic dominants, inherent in modern practical philosophy. The author emphasizes the polyconceptual and interdisciplinary factors that necessarily arise when trying to analyse a social contract, logically directing the inquiry to identify the basic criterion of modern society, which, according to the author, is the legitimizing potential of a social contract, with the intention to transform the power and ideological criteria. The author notes that the modern postliberal and (post)political world has a paradoxically global-local dimension, and in recent years hybrid contractual criteria that can not be subjected to unambiguous analysis become dominant. Apparently, semantic corrosion is perceptible through the prism of the total power of media in modern society, already virtualized and polymorphic in its premise. The author infers the need to intensify global efforts to overcome social challenges facing global civilization in general and Ukraine in particular. The author notes the chaotic and unstable postconventional Ukrainian society of "late modernization", where there is virtually no clear and well-founded diagnosis of social order. As a result, the author draws a parallel with the establishment on the planetary scale, where legitimate institutions of the world community can not claim universal significance, since the global civil society has not yet been formed. The author emphasizes that in the modern era of hybrids, special attention should be paid to the problem of transformation of power-legitimation discourse, which is defined in the dissertation through the idea of a rehabilitated social contract with the value dimension at the level of the communication paradigm. Thus, the modern concept of social contract in the author's interpretation, serving as the leading marker-notion of Modernity, continues its non-linear progress in the network society of the XXI century in the light of the modern practical philosophy discourse.
