[Abstract] The approach to environmental complexity in this text dissociates itself from the notions of physis generativity, the ecologization of the mind, the sciences of complexity, interdisciplinary methods and complex thought. Environmental complexity is conceived from the perspective of a crisis of knowledge, the objectification of the world, the intervention of knowledge about nature, and the appearance of hybrid entities that go beyond the traditional meaning of ontology and epistemology. Environmental rationality is based on a new meeting of the real and the symbolic, on the resignification of the world and nature, on a network of relationships of otherness among beings, and on a dialogue of knowledge, where the being is reconfigured, its identities are reconstituted, and new social actors are created within a policy of difference guided by the desire for knowledge and justice in the social reappropriation of the world and nature.

[Resumo] A análise da complexidade ambiental neste texto demárcase das visións da xeneratividade da physis, da ecoloxización da mente, das ciencias da complexidade e dos métodos interdisciplinarios e do pensamento complexo. A complexidade ambiental concíbese na perspectiva dunha crise do coñecemento, da obxectivación do mundo, da intervención do coñecemento sobre a natureza e a emerxencia de entes híbridos que desbordan o sentido tradicional da ontoloxía e a epistemoloxía. A racionalidade ambiental fórxase nun reencontro do real e do simbólico, na resignificación do mundo e da natureza, nunha armazón de relacións de otredad entre seres e nun diálogo de saberes, onde se reconfigura o ser, se reconstitúen as súas identidades e se forxan novos actores sociais nunha política da diferenza guiada por un desexo de saber e de xustiza na reapropiación social do mundo e da natureza
