The natural ontology for quantum theory, and most particularly for relativistic quantum field theory, has close similarities to key aspects of Whitehead's process ontology. Both are built around psycho-physical events and objective tendencies (Aristotelian ``potentia'', according to Heisenberg) for these events to occur. On Whitehead's view, as expressed in his Process and Reality (Whitehead 1978), reality is constituted of ``actual occasions'' or ``actual entities'', each one of which is associated with a unique extended region in space-time, distinct from and non-overlapping with all others. Actual occasions actualize what was antecedently merely potential, but both the potential and the actual are real in an ontological sense. A key feature of actual occasions is that they are conceived as ``becomings'' rather than ``beings'' -- they are not substances such as Descartes' res extensa and res cogitans, or material and mental states: they are processes.

Quantum Ontology and Whitehead
The current Journal of Consciousness Studies included an interview of Henry Stapp by Harald Atmanspacher (here’s my most recent post about Stapp; Atmanspacher is also a physicist interested in consciousness). I’ve been a bit skeptical in the past regarding Stapp’s specific proposals for how quantum effects are implemented in the human brain, but I mostly agree with his metaphysical views, including the connections he draws between the ontology of quantum mechanics and that of Whitehead. Below is one paragraph from the interview which I thought captured this well.
