In one paragraph

Chris Fields builds on a forthcoming paper in the journal Mind and Matter ("Embodied Cognition, the Free Energy Principle, and the Unity of Science") that argues against physicalism, and places it in the lab's current Platonic-space discussions. He goes from the Platonic space to the space of current mathematics, to physics seen from the top down, to each observer's experiential world, and ends at panpsychism.

Main ideas (plain words)

  • He distinguishes the Platonic space from "the math space", the mathematics we have now.
  • Current physics, he says, lets and often requires us to think top-down, with symmetry principles doing most of the explaining instead of building biology up from particles.
  • The physics pattern space is a small part of the math space, and any interaction between physical systems can be modeled as exchanging finite bits, that is, as communication.
  • Each system has its own experiential space, limited by what it can detect and compute.
  • He calls for a formal language linking structures in the Platonic or math space to what observers like us can actually observe, respecting resource limits.

"this current physics allows us and and often actually requires us to think top-down not bottom-up."

"I think as soon as we embark on this route, uh we end up at panpsychism in a pretty natural way."
