Abstract
In the present article, I propose to give a positive characterization of ontological emergence from a relational
perspective that, in opposition both to atomism and to holism, defends that the existence-conditions, the identity and the behavior or causal role of any emergent entity are to be conceived, and explained, as constructed by diverse systems of qualitatively transformative relations. I argue that from this relational perspective, the notion of emergence can be seen as ontologically and epistemologically coherent and significant. Finally, I try to show in what sense, and to what extent, the Nonlinear Quantum Physics, as developed by Croca and his team, expresses such a relational and emergentist view of physical reality.
