Background. The main problem the world faces today is the crisis of personal identity. It began with the events of the year 1968 that is considered to be the starting point for the postmodernist worldview and resulted in significant social cultural consequences.
The Objective of the paper is to discuss these consequences, to analyse how the ideas of pluralism, tolerance and the maximum actualisation of personal freedom that lie in the basis of the postmodern society cause radicalism, fanaticism and hypocrisy.
Design. The author examines socially disintegrating and disadaptation-related tectonic societal processes associated with the breakdown of customary values and attitudes, state forms, emergence of radical communities and migration issues, whose consequences are frighteningly unpredictable. It shows that the phenomenon of “escape from freedom” described by E. Fromm was embodied in the rudimentary forms of hyperidentity arising in the technological and information society.
Conclusion. Postmodernism today is becoming a mirror of the permanent crisis, either economic, political, intercultural, inter-ethnic, interconfessional, intergenerational ones. The result of the hopes of the year 1968 was a maladapted post-normal society that lost its ability to invent meanings and constructive models of self-identity further replaced by rigid and rudimentary forms of identity.
The paper proves the assumption that being a worldview of the information society postmodernism simultaneously reverberates its problems, among which is blurring personal identity. The most vulnerable part of the postmodern ideology is the implicit inability to construct steady architecture of identification. This is hampered by specific ideas related to the fundamental principle of postmodernism, i.e. pluralism leading to relativism and the loss of sustainable landmarks. Applying the pluralism principle to the full may result in unlimited choice production, which should not be considered the achievement of the information society and postmodern culture, but its main problem. The social political consequences of tolerance issues and the equivalence of opinions, attitudes and values are discussed. Lack of preferred self-identification vectors reduces the motivation for the individual to develop a stable personal identity. If no paradigm in terms of the truth can claim a given status disputes over claims of significance turn into controversies over power, thereby generating social Darwinism. The principle of pluralism actually legitimizes radical ideologies, whose extreme form is terrorism put in the mosaic and multicultural postmodern world occurs to be one of many sociocultural paradigms. Exactly the identity crisis in the conditions of mass distribution of both military and information technologies is considered the main cause of radicalism as the result of finding pathological forms of cognitive personal identity. Social cultural and worldview crises of the information society are becoming the main cause for producing endurable and irregular forms of personal identity architecture.
