They write that the statement, "The particle has position x and the particle has momentum p", is "completely meaningless (not even wrong)". (page 21)
But that is what I like about positivism. Physicists with that perspective take evidence seriously even if it is not repeatable.
Although I tend to agree that one needs to keep evidence close at hand, none of us can stop believing (aka conjecturing, aka philosophizing). We are all knee deep in philosophy and some of us have waded into the deep end. Which I suppose means that we have lost the solid ground of evidence under our feet and have only reason to rely on.
The problem is everyone believes something. A deeper problem: some of us don't think we believe the facts we know are true.
I was thinking about the mathematical model E=mc^2.
From an engineer's perspective that model is useful and convenient in getting nuclear power plants to work.
From a philosophical perspective, (perhaps out in the deep end, but who knows?), this relationship between energy and mass suggests there may be a similarity and a non-dualistic (aka monistic) relationship between consciousness and matter. It doesn't help determine which side wins out, energy or mass, but at least the concepts of "energy" and "mass" are better defined than "consciousness" and "matter".
