NowAgnostic:If the scientist has directly observed the contrary happening then he can flatly say the metaphysician who said such a thing was “impossible” is wrong. Even if the contrary is not directly observed, but only inductively inferred, he can still take the metaphysician’s view as a hypothesis which can be tested, insofar as it makes a prediction, and evaluate it on that basis, and find it highly unlikely, which is what “disproved” means in science most often.
And I am saying that when metaphysics makes empirical predictions it moves over into the domain of empirical science, and cannot expect to insulate itself from the scientific method and verification or disproof.
Science isn’t restricted by methodological “naturalism” either, although the definition of “naturalism” is somewhat hazy. Science can entertain as a hypothesis, for instance, that angels are pushing the planets and stars around.
Yes, it is the case.
The “quantum nothingness” makes the event possible, yes. That doesn’t mean that “quantum nothingness” can be in any sense held to be an efficient cause without changing the meaning of the term as metaphysicians understand it. It is an irreducibly random event, as best as we can tell. Local hidden variable theories have been disproven. An irreducibly random event can have no “cause”. Or, to use more metaphysical language, yes, the quantum vacuum provides the potency for a virtual particle to arise, but it does not provide the act, the potency’s reduction to act appears out of nowhere, unexplained and uncaused.
Yeah, but come on, all interpretations of QM cause some problems.
Well the natural sciences can just say, we don’t know, but shut up and calculate. But the metaphysics will say a particle is supposed to have a definite place and a definite velocity, and it should not matter whether we bother to measure it or not.
I disagree, and let’s not equivocate on “interpretation”. The “interpretation” of observation in the natural sciences is analysis of whether a given hypothesis is supported or disproven. This is done via mathematics, not dependent on one’s metaphysical view. Now of course we have the Copenhagen “interpretation” of QM, the many-worlds “interpretation” of QM, etc., this is not what I mean by “interpretation”; these are not scientific interpretations.
Now I would ask do you agree that a metaphysical prediction can be falsified using the scientific method?
I agree with this.
This is a metaphysical assumption science must make, along with the other disciplines, yes.
You have to know that I would ask the next questions: “What exactly is a ‘virtual particle’”?Have scientists laid eyes on one yet? Do we have a super microscope I don’t know about? If these quantum fluctuation thingys have less substantial proof than an electron, how are we to know that they are “matter” and not just some energy discharge?
Why are they spoken of as virtual?
