<p>In sustainability science, a profusion of research is directed toward the shifting paradigms and inner worldviews needed to pioneer solutions to the sustainability crisis. Human–nature relationships and connectedness to nature are at the center of these discussions. However, such discussion reveals the even deeper paradigm supporting it: the dualist framework that manifests itself in oppositions, such as mind/body, human/animal, ecological/social, object/subject, or empirical/rational. Beyond these dichotomies, dualism surfaces in the complex nature of sustainability conflicts and can hinder their mitigation. This study addresses the problem of dualism and dichotomous thinking and examines it through foundations of western rationality, specifically the Law of Noncontradiction and the Law of Excluded Middle. To dismantle dichotomies, I introduce a complementary dialectical paradigm that enables viewing apparent dichotomies as intertwined and interconnected. To take a solution-oriented approach, the paper presents a new framework that reimagines the harmful human/nature dichotomy, to help mitigate practical conflicts. The framework analyzes oppositions with four paradigms: dichotomous-dialectical and dualism-pluralism through which dichotomies or complex conflicts in the context of sustainability can be examined. What is more, the framework makes it possible to manage tensions between different viewpoints and to approach contradictions as a relevant type of relationship in the world in general which is useful in sustainability science. Finally, I will provide two applications of the framework, one addressing human/nature dualism and the other addressing a human–wolf conflict to illustrate how the framework can be applied in sustainability science.</p>
