This research will begin with the statement that the Merriam-Webster dictionary defines science as the knowledge or practice acquired systematically. This is the broadest possible definition. However, and not only for the purpose of this essay, the science should first of all be understood as the systemic process of acquiring knowledge, primarily through the process, or better to say a method, of trials-and-errors, that can be understood as the postmodern procedural attachment, to the overall conception of science, stressing the importance of this scientific attribute as the only way how to acquire the real and true knowledge. The first scientific effort to rebuilt political science in the manner of natural sciences can be found in the work of Ch. Merriam and H. Lasswell. Merriam in his New Aspects of Politics written in the 1920s criticised politology for the lack of scientism and required its interaction with other sciences such as sociology and psychology. Similarly, G. Catlin also supported this criticism in his work Science and Method of Politics and the key assumption that power is the core and dominant subject that political science should focus on. Catlin also called for the strict freedom from values, originally M.Weber´s postulate, which played a significant role in the formation of the empirical theory of political power and behavior. It is little known that UNESCO influenced the development of political science as a science as well by its patronage over the establishment of IPSA and the first international congress on political science in Paris 1950....
A radical change is going on in front of our own eyes and it will undoubtedly modify the history of humanking irrespective of how we decide to thematize and define its symptoms. For example, the emergence of global civil society and domination of liberal democratic arrangements in political systems over the world. We can observe some specific postmodern trends in the field of science (and political science), its methods, approaches and "technologies" as well.
The most relevant characteristic of postmodern science is its utilisation and benefit from the results of Second scientific revolution, especially the consequence of Einsteins theory of relativity (1905, and 1911-1916), Heisenbergs uncertainty principle (1927), Godels incompleteness theorem (1931), and later Thoms theory of catastrophies (1975), Hakens synergetics and theory of chaos and non-equilibrium systems (1974, 1983). The pragmatic paradoxes, paralogics, open and close systems, discontinuity, and turbulence, deterministic chaos became core themes and remained in the spotlight of postmodern science until now. The opportunity to conceptualize the unprecedented model of legitimization, that does not any longer account for effectivity but for the difference understood as paralogic (the unintentional breach of logic principles in process of reasoning), the inventive imagination development.
The political science stands on the beginning of the new era imposing new demands on its focus and methods, and expecting new views and implications. This approach has been labelled as the triumph of postmodernism throughout last forty years. For this quite long period of time, postmodernism was successful in obtaining the status of selfconfident
