Key word "epistemological subject"

The author provides a comparative analysis of the approach to cognition in the theory of self-organization and radical constructivism from the position of synergy between man and nature. It is advanced the idea on the basis of radical constructivism representatives’ concepts by such authors as H. von Foerster, H. Maturana, F. Varela, N. Luhmann, F. Wallner that epistemological subject should be considered as a complex self-organizing object. Its cognitive activity takes place according to the logics of synergetic models. The author proves that cognition based on the constructive realism is the most appropriate to the modern stage of epistemology development as it cancels the opposition of constructivism and realism to some extent as the cognition process from synergetic point of view is an act of projective and constructive thinking which is open for further criticism.
