Relation as the Missing Subject: A Unified Restatement of Eight Quantum Puzzles from Relational Ontology

Z J Yang

The mathematics of quantum mechanics has been consistent for a century, yet "what it actually says" remains unclear. We argue this is fundamentally a linguistic problem: classical language lacks the correct ontological subject. The missing subject is "relation"—a precisely defined structural primitive. Using relation as the unified subject, we restate eight core quantum phenomena (double-slit, wave-particle duality, collapse, entanglement, uncertainty, complementarity, EPR, tunneling) in a single coherent narrative. All restatements are mathematically equivalent to standard QM; the contribution is a more complete interpretive language. We position this as non-local relational realism, distinct from Rovelli's epistemological RQM.

Bohr and the Measurement Problem: Moving towards Holism in Copenhagen

John Lawrence Benich

This thesis is an examination of the measurement problem from within the Copenhagen interpretation of quantum mechanics where I take issue with von Neumann’s theory of measurement which argues for the subjective collapse of the wave function by a conscious observer. I argue that von Neumann’s postulate of collapse has led to several intractable philosophical and conceptual problems in its account of quantum measurement. I argue that these problems arise from von Neumann’s misreading of Bohr’s complementarity regarding the relationship between subject and object as distinct metaphysical entities. Instead, I offer a new way of defining the subject-object relation based on Don Howard’s reading of Bohr’s complementarity as subject-object nonseparability (SON). I argue that the SON principle has the potential of placing Copenhagen on more solid philosophical footing by viewing the subject-object relationship not as a causal relation, but as a relation of ontological dependence to avoid the idea of collapse altogether.

Contextual Spacetime and the Making of Classical Reality - Part 2: Tiers of Subjectivity and How Informational Worlds Construct Subjective Amalgamations of Time

Allan Porter

My fundamental theory of how information, subjectivity, entropy and time are all intimately related and exist as part of a larger phenomenon.
