Complexity is not the point here. The rules of probability theory can be applied also in arbitrary complex situations. The prior is the state without information. It is the state with maximal entropy. This is unproblematic and well-defined. Entropy is a well-defined function on the space of...

Yes, I'm aware that this subthread about the consistency of the thinking of those who reject realism and causality in Bell discussions but use in in everyday life and in other scientific questions is already off-topic. I have referred to Jaynes because his use of the "robot" solves a similar...

I understand this point, and your description of how you behave fits in what I think happens. I would describe it as "you use your common sense realism and don't care about consistency with some 'formal realism'." But I think it is wrong to ask that 'formal realism' for some separate...

[Moderator's note: This thread has been split off from a previous thread since its topic is best addressed in a separate discussion. This post has been edited to focus on the topic for separate discussion.] Jaynes has used in the derivation of the rules of probability as the logic of plausible...

It is completely legitimate to develop theories which do not presuppose a 4D background. If they succeed to explain more, for example, explain why our spacetime is 3+1 dimensional, fine. But it is also completely legitimate to start with a classical fixed background of absolute space and...

The average researcher interprets QM as "shut up and calculate", without thinking too much about philosophy. Only a small minority cares about Bell. And those who care, and follow the mainstream (that means, giving up realism and causality with common cause principle) forget about this...

I explained why. They continue to use in everyday life as well as in their everyday research realism and causality without even thinking about the justification for this. That they question this justification in discussions about Bell's inequality they don't even recognize. Questioning...

The point of Bell's theorem was a philosophical one - to show that Einstein causality has to be given up if one wants to preserve a realistic worldview. Falling back to the Lorentz ether is fine, it is what solves all the quantum foundational problems (as shown by the realist interpretations)...

Ok, this has at least some plausibility. To introduce conservation laws into a field theory is known to be problematic. I know (memory, without good sources, sorry) that this creates some problems in condensed matter theory too. Take a particle theory with exact conservation law. Then you...

The point being? I have included a source term. I would ask you to show me which part of the coupled system makes it non-hyperbolic. Is the equation for the matter fields not hyperbolic?

##\square A^\mu = j^\mu## not hyperbolic? Then, what has your "without gauge fixing" to do with my "in the Lorenz gauge"? Are you about the remaining gauge freedom after the Lorenz gauge?

I think one has to understand the reason why there are so many interpretations. Why does one start to create a new interpretation of QM? To make sense of this strange theory. And the problem is not the measurement problem and so on. There would be no problem if this would be a particular...

Ok, then I give up. "The scalar photons are treated by using an indefinite metric" Gupta, S.N. (1950). Theory of longitudinal photons in quantum electrodynamics, Proc Phys Soc A 63(7), 681-691 "Gupta has introduced an alternative method of quantization for the Maxwell field which differs...

And therefore this can be something not really existing now, without violating classical as well as EPR realism. For the realistic interpretations of QT this is not a problem at all, reality is defined by the configuration, the only real "measurements" are measurements of the configuration, and...

You have not got the point that I'm not afraid of ending up with a gauge theory? My point is that this does not require that the ##A^\mu## should be handled as completely unphysical fields living in an indefinite Hilbert space of the Gupta-Bleuler resp. BRST approach. One possibility would be...
