The focus on literature in the 1980s was mainly related to the need to find the common
points between classical realism and neorealism, to differentiate this school of thought
from the neoliberal current or new institutionalism. Nevertheless, there were also
theorists who sought to find a point of reconciliation between the realist current and the
neoliberal current (Niou & Odershook, 1991 apud Buzan, 1993: 2-3); an example can be
found in the work of Hedley Bull (1995) on international society and international
anarchy. This led some field theorists to accuse the discipline of losing its orientation,
falling on a lack of substantive progress (Holsti, 1985: 1-2; Fergunson & Mansbach,
1988; Onuf, 1989: 8 apud Buzan, 1993: 3-4). For the reflection intended to be made,
the most relevant criticism about the loss of orientation of the discipline was the fact that
all theories developed on erroneous premises, such as international anarchy being
considered the central and fundamental principle of International Relations, when it
comes to Onuf (1989) of an empty concept (Onuf, 1989: 14).
It is necessary to clarify that although Kenneth Waltz (1979) was a pioneer in the
application of structuralism in International Relations, specifically within the Realistic
School, structuralism was a movement that dominated social sciences in the 20th century.
Structuralists insisted that social sciences must go beyond self-conceptions because
individuals are constrained by structural forces over which they have no control and may
not even know exist (Buzan, 1993: 5). Buzan (1993: 6) advances that this structuralist
approach makes it possible to break with the state of nature assumptions to ground the
behavior of agents, according to a realistic logic.
Still, for Kenneth Waltz, the structure has three dimensions: ordering principles (i.e.,
anarchy), differentiating principles, and capacity distribution (Waltz, 1979: 79-101 apud
Wendt, 1995: 134). These aspects, although they highlight the disposition of the agents,
do not allow us to understand their behavior, since this factor depends mainly on
intersubjectivity (Wendt, 1995: 134), a concept that is unrelated to waltzian theory.
Waltz's criticism is not related to the structuralist character of his theory, but to the fact
that it is characterized as anarchic and the approach to conflictgroups as an object of
study, to achieve the realistic premises mentioned and justify the logic of power of the
international system. Criticism is specifically directed at the realistic assumptions and not
at the generality of its structuralist approach. This criticism is based on the Wendtian
assumption that the structure consists of material conditions, interests, and ideas
(Wendt, 1999: 139), which with intersubjectivity imply that the structure is socially
constituted – i.e., dependent on a process of socialization.
From the assumptions presented about structuralism, there is a relationship between the
concepts of structure and state of nature that deserves its proper clarification,
understanding what is considered a process of socialization and as post-social.
The order of thought should be inspired by Waltz (1979) and Aron (1968) and, like these
thinkers, from anthropological assumptions, inspired by Rosseau, to view the state of
nature as a non-systemic state where there is no social structure, because political units
are isolated, unaware of the existence of others. Only when political units begin to
interact with each other – when the process of socialization begins – the international
system is formed (Buzan, 1993: 68-70) and the structures that characterize it emerge.
As for Waltz, the ordering principle of the structure that characterizes the international
