Ontology I: From Brain to World–Brain Relation

Abstract

How can we account for the brain’s existence and reality? I now shift my focus from the empirical (Part I and II) context in the previous chapters to the ontological dimension. Specifically, I focus on an “ontology of brain” as part of a wider “philosophy of brain” (Northoff 2004). Based on the empirical data, I argue that the brain’s existence and reality is based on structure and relation rather than elements like properties. This makes possible to determine the brain’s existence and reality by world-brain relation rather than physical or mental properties within the brain itself. That is well compatible with ontic structural realism (OSR). More specifically, the world-brain relation can be understood in spatiotemporal terms entailing what I describe as “spatiotemporal ontology”. Time and space are here no longer understood in observational terms, e.g., “observational time and space”, but rather as relational in the sense of OSR, i.e., “relational time and space”. Taken together, I ontologically characterize the brain by world-brain relation presupposing relation and structure as in OSR. This amounts to a “relational view” of the brain in our “ontology of brain”. Such relational view of the brain’s existence and reality can be specified by “relational time and space” (as I say) as distinguished from “observational time and space”. That opens the door for a novel ontological characterization of consciousness in the terms of world-brain relation and OSR – this shall be the focus in the next chapter.
