Don’t Squint: Quantum Hylomorphism Can Solve Albert’s Macro-Object Problem
Abstract Primitive ontology (PO) approaches to quantum theory aim to describe the world in terms of matter distributed in 3-space (the PO). David Albert argues they cannot recover macroscopic structure without ad hoc coarse-graining (“squinting”). This paper formalises a Macro-Object Problem for the PO-approach based on Albert’s critique and enlists Contextual Bohmian Mechanics (CBM) to offer a solution. CBM augments the PO with a local context field $$\Lambda (x,t)$$ . While $$\Lambda$$ is fixed, the wavefunction $$\Psi$$ evolves unitarily and the particles Q follow a Bohmian guidance law; when $$\Lambda$$ changes on a bounded region R , a local completely positive instrument updates the state, with open-system energy bookkeeping and statistical locality outside R . I show that $$\Lambda$$ tiles spacetime into macro-object tokens, modulates the dynamics to confer genuine causal powers, and does so entirely within 3-space—thereby satisfying all the conditions for solving the Macro-Object Problem. I argue that physical objects are hylomorphic composites of both matter (hylē) and form (morphē), with matter corresponding to the particles and $$\Lambda$$ serving as a rigorous surrogate for local form.
