This essay formulates some premises of interdisciplinarity. The ideas are critically and generally expressed but the references content, presented in the paper, are thematically precise (they are generally of speciality). These references also support the dowbts re- garding this issue, that are critically expressed in the pa- per. The interdisciplinarity is a real fact (a reality) but even a neutral and optimistic analysis of it should start in a critic spirit. The interdisciplinarity is not a miraculous solution to all the (...) difficulties we encounter while trying to understand the complex world we inhabit. It is men- tioned that the main considerations of this paper are ex- pressed in an epistemology view. (shrink)
