“Most tantumising state of affairs”: Mathematical and non-mathematical in quantum-like understanding of thinking

“…Given that Heisenberg’s derivation of QM ( Heisenberg, 1925/1968 ), which depended on (3), is not my concern here, I shall only mention (3) in passing (I have considered his derivation on several previous occasions) ( Plotnitsky, 2021c ) (pp. 101–144).…”

“…I consider next the concept of reality-without-realism (RWR) and the RWR view, which grounds the present and related interpretations of quantum theory, such as that of Bohr, as well the present interpretation of Q-L theories and models. I have discussed this concept previously, most extensively in Plotnitsky (2021c) . It is grounded in more general concepts of reality and existence, assumed to be primitive concepts and not given analytical definitions.…”

“…There are several reasons for my choice of “classical causality,” rather than just causality, used more commonly. The main one is that it is possible to introduce alternative, probabilistic, concepts of causality, applicable in QM or QFT, including in RWR-type interpretations, where classical causality does not apply (e.g., Plotnitsky, 2021c , pp. 207–218).…”

“…That, however, was not Bohr’s view, at least after he abandoned his Como argument ( Plotnitsky, 2016 , pp. 122–125; Plotnitsky, 2021c , pp. 67–68).…”

“…It only makes claims concerning our interactions with the world, which are irreducibly probabilistic in dealing with quantum phenomena. The world, apart from the human world, has no probabilities, and makes no measurements or predictions; only we do, and quantum physics helped us to realize this fact ( Plotnitsky, 2016 , 2021c ). 7…”
