Abstract. The systemic principle uses the deduction and the induction, analyse and synthesis, inferency and proferency, in order to find out the interdependencies and the inner connections that make mooving the complex organized entities. The true valences of this approach can be found neither in the simplist models of the “in-out” type, nor in the “circular” models that fill in the Economics and Management handbooks, and that consecrate another kind of formalism, but in the constructiviste-reflexive strategies, used in order to explain the economic and social structures.

Keywords: holism, complexity, feedback, meta-controle, antropocentrical systems, constructivism.
