Systems ecology in the style of Howard Odum was the prevailing ecological field in the period
1950-1970 and declined afterwards. Nevertheless, in 1992, three outstanding system ecologists, Bernard
Patten, Sven Eric Jørgensen and Milan Straškraba began publishing a series of papers in which they
attempted to introduce some new perspectives on ecosystems and make systems ecology flourish again.
The work hypothesis of this essay is that Patten and coworkers would have a better fate than their
precursors, if their approach to ecosystems enabled the systems ecology to face both the past internal
anomalies and the social incompatibilities. To test this hypothesis, I am searching for how they handle
the old worrying problems related to the field’s hallmark, namely holism. As a matter of fact, Patten
and coworkers rather spontaneously borrowed conceptual resources from the domain of social network
theories such as Actor-Network theory and make it possible for systems ecology to cope with the failure
of Howard Odum a) to define ecosystem boundaries as naturally existing b) to treat the ecosystem as a
biological and not as a physicochemical entity and c) to offer a unified but pluralistic framework for
studying ecological entities. While the innovations introduced configure problem-solving strategies,
Patten and coworkers avoid dislocating the former structure. The latent ideological assumptions of the
old field are not questioned and the beneficial potential of the innovations is not activated. Patten and
coworkers interpret innovations from a viewpoint overarched by scientific romanticism and the
technocratic worldview, a matter that inevitably brings back the old problems and prevents the field
from harmonizing itself with the contemporary and prevailing social ideas and ideals.
Keywords: Systems ecology, Actor-network theory, Scientific romanticism.
