Decidability, computability and predictability are related to Realism and undecidability, uncomputability and unpredictability are related to Anti-realism. In physics, Newtonian Mechanics is based on decidability (certainty), while Quantum Mechanics is based on undecidability (uncertainty). As at present, it is not known whether Physical Reality is Newtonian or Quantum mechanical. Here I argue that Physical Reality will eventually be recognized as Newtonian, and hence the three pillars of Anti-realism will not have any role in it.
