The paper explains the heuristic approach to the dialectical interaction of the individual sciences and philosophy as the science of the universal (the issue of which is extremely important in the context of the ongoing reduction in the last teaching, evaluated as "non-core discipline"). As an example of such a heuricity, the author considers ideas of quantum theory creators, who contributed to the fact that in the framework of non-classical science objectivity of knowledge began to be understood in the aspect of "the adequacy of the theoretical description of reality" (which allows alternative, but equally appropriate options of such descriptions). The most striking example of the consequent impossibility of eliminating the "observer" of the scientific picture of the world is "uncertainty principle" as a special case of "principle of complementarity".
