The concept of international configuration

regulation. Above all, a social structure is something singular which represents the
whole, where all the elements that constitute it form a set. This set has properties that
differ from its elements when considered individually. However, this wholeness is not
static, and its dynamism generates transformation processes, develops its own
potential, goes through stages of growth, consumes energy in the process, and,
ultimately, tends to disintegrate. Effectively, these transformation processes end up
causing inevitable disequilibria. This is due to the dissipation of energy (entropy) and
subsequent exhausting of the potentialities, which require the existence of
compensation devices capable of correcting disequilibria through self-regulation
mechanisms. According to Piaget, those three elements are vital to our understanding
of the idea of structure: the creation of a coherent whole, a capacity to adapt and
transform, and the existence of tools to readjust the whole.
The concept of system, very much present in distinct scientific fields, and at the core
of a vast number of theories, stands quite close to that of structure. In the field of
international relations, systemic analyses have become widely used, as well as the
expression “international system”, even in non-scholarly language. Systems theory has
been used in several interpretations of the internationalisation processes. As Morton
Kaplan earned fame for his inventory of possible international systems2, Kenneth Waltz
took this theme to the sphere of “realist” classical thought by applying systemic
theories to the study of international relations, which granted him the classification of
“neorealist”3.
Returning to the concept of system per se, among other in-depth studies on the topic,
one can emphasize the work of Georges Lerbet4. In his view, system adds the notion of
interaction with the milieu to the idea of structure, which translates, basically, into the
exchange of energy between the structure and the environment surrounding it.
Between the dynamic wholeness in question and what surrounds it (the
“surroundings”), a regular exchange of interactions occurs, a two-way flow of energies
where we indeed find the idea of system that results from this new mixture of structure
plus network of interactions. Systems can be closed (like those in machines) or open
(such as those in living beings, either biological or social ones). In the case of the
latter, the exchange of energies can take up several forms, such as, for instance,
material flows or information flows. For some authors, the analysis of systemic
processes can be done according to the cybernetic model of input, output and
feedback, through an action and reaction complex.
The truth is that specialists almost imperceptibly slide from the concept of structure to
that of system in the vocabulary they use, as if the two concepts were synonyms.
Often, structure is given a predominantly static meaning, whereas system is presented
as an essentially dynamic meaning. One just has to read the book that is probably the
most complete work on the application of the concept of system to international
relations, authored by Michael Brecher5. He writes that “a system contains,
