DOWNWARD CAUSATION AND RELATEDNESS IN EMERGENT SYSTEMS: EPISTEMOLOGICAL REMARKS

In this article we analyse the problem of downward causation in emergent systems. Our thesis, based on constructivist epistemological remarks, is that downward causation in synchronic emergence cannot be characterized by a direct causal role of the whole on the parts, as these levels belong to two different epistemological domains, but by the way the components are related: that is by their organization. According to these remarks downward causation, considered as relatedness, can be re-expressed as the non-coincidence of the operations of analysis and synthesis performed by the observer on the system.
