Can Quantum Field Theory help address the Subject Summing Problem?

The subject summing problem poses a major challenge for panpsychist theories of consciousness: it seems implausible that the micro-subjective experiences of the billions of particles in a human brain could combine to form a single unified conscious subject. This paper explores the impact of Quantum Field Theory (QFT) on several proposed solutions to this problem. Specifically, I argue that QFT challenges the standard conception of everyday objects, from molecules to chairs to individual people, as mere aggregates of subatomic particles. Instead, objects associated with bound states or resonances are better conceived as unified entities. The implications of this claim for the subject summing problem depend on one’s preferred ontology for QFT: a particle ontology resembles Combinatorial Infusion approaches, while a field ontology parallels cosmopsychism. Both connections are explored in turn. Additionally, QFT suggests a new version of the combination problem: since bound states are ubiquitous, everyday interactions may frequently produce unified physical objects without an apparent merging of conscious experience. While this work is not intended to be conclusive, it highlights the importance of integrating fundamental physics into metaphysical discussions of consciousness.
