Complex Systems in Psychophysiology Represent the Eect of “Repetition without Repetition” (N. A. Bernstein)

The discussion of special properties of living systems still continues. The authors present a new understanding of complexity and systems of the third type (W.Weaver) in the new theory of chaos and self-organization, as well as in postneclassic(V.S.Stepin). The paper explains ineffectiveness of applying stochastics and deterministic chaos (I. R.Prigogine, J. A.Wheeler and M.Gell-Mann) for describing complex biological systems. The authors introduce a new concept of homeostatic systems. These systems are in continuous random motion. Thus, statistical methods are inappropriate here. The authors dene the limits of modern deterministic and stochastic science in describing complex homeostatic biological systems. These propositions signify a new stage in the development of the philosophy of science and the science of nature (complexity) in whole. The eect of “repetition without repetition” (N. A. Bernstein) which is now quantitatively described by the eect of Eskov–Zinchenko underlies this dierentiation.
