Sciences pratiques et pratique de la science

Abstract

How and to what extent should the sciences of man be associated to practice and action? a rational knowledge of man's behavior has to construe a concept of action, effective in the process of determining the very fields of research. moreover, it seems to require a specific type of models, combining two levels of organization: "informational" and "energetic". the chief difficulty lies in expressing formally and operationally the interplay of such systems.
