Synergetics, interdisciplinarity and postnonclasscal science of the 21th century

We consider a subfield of the philosophy of science connected with a forecast of the development of the fundamental cognition trends. We propose an opinion based on the interdisciplinary approaches of modern science, on the logical and methodological analysis, on the theory of rationality types risen by V.S.Stepin and on the postnonclassical ideas.
We show that in a bifurcation point, which is passing nowadays by the cognition, principal difficulties for continuation of a number of investigation programs arise, although new possibilities and prospects appear. Limitations in the field of science, which cause growing awareness of researchers, as well as rapid and profound change of the knowledge subject that awaits us in the coming decades are considered.
