The theory supposedly being tested is used to do the testing... And the interpretations of the results...
So, what non-causal methodology do scientists employ to validate the causality of the macro world? Or do they employ causal theory to test their causality model?
That's an attempt to reductio ad absurdum but it's really a false analogy fallacy.
The difference is that at a macro level we have a direct/empirical acces to the phenomena we experiment upon.
See, for example, quantum microscope.
The algorithms used to program these computers are directly issued from the QM 'theories'.
The data, is not only interpreted through QM but collected and even
created by the 'theory'.
Also, what is a non-causal methodology, please?
What is a theory that gives only a probability of numerous events to occur, not the actual occurrence of individual phenomenon?
One can equally ask the inverse, what is a theory that gives only an actual occurrence of individual phenomena, and not a probability of numerous events? Your implication is that one assumed theory - causality - is somehow more legitimate than the other by fiat.
You use the same method.
A theory should not only describe but
explain phenomena and predict accurately the
actual occurrence(s) of
actual events (individually
and by set).
QM doesn't explain anything, doesn't give causes to events to happen as its stance is
randomness.
How to get rid of the difficult and complex (
scientific) work of finding the causes? Easy, simply states there are none... Fantastic...
That's scientific method(ology)... right.
More, QM doesn't predict
actual events. How could it since it proclaims an absence of cause??
That's why the use of probability and statistics is required in QM and that's no prediction at all.
Therefore QM is NOT a theory.
Also, an a-causal world is an a-scientific/illogical/irrational world.
I understand why you desire to use QM to disprove materialism... Since you believe in God and in a spiritual level of existence (the soul and all...).
But isn't it totally dishonest to use QM to disprove materialism and at the same time believe and defend a (meta-)determinism of 'reality'?
Also, causality cannot be "the rule" at the highest level, or else you'd be invoking infinite regress. At some point, one must have an acausal cause, or else reason itself crumbles.
You know the problem with this assertion.
How could (why would) God have no cause for Its existence?
We reach the limit of our understanding of reality here.
We also can say that if God can have no cause for Its existence, why can't the universe? Threfore render the necessity of a God null.
The universe could have always existed.
Because the Big Bang theory seems to be false.
That's why I'm agnostic. I have no shame in saying I don't know and I have no need for a reson/truth we obviously know nothing about.
You choose to believe to compensate this lack of knowledge. I don't. My belief would be irrelevant to the 'true' nature of reality. I don't childishly or delusionnally desire to know something we don't possess the intellectual capacity to know... yet.
@The belief doctor:
You sound like a professional philosopher who's not sufficiently confident to expose their real identity. Not much substance or credibility in that.
You don't need to know my name to debate on the ideas I develop.
I don't care about your name. Does narcissistic exhibitionism need to be the rule for you to be satisfied?
So much of your reply carries little weight, being largely, from what I understand, empty (... don't know quite the right description), but not much of anything.
And yet 90% of the problems I develop aren't addressed at all. Everything seems empty when you dismiss 90% of un inconvenient 'reality'.
"Where is your proof?
Because claiming "Newton physics is wrong because quantum physics is right" is no proof. "
A thought experiment is free of demonstration (premises, inference and conclusion) now?
Well, it's a useless 'thought expirement', then.
I still don't see (even a logically argued) proof here.
Okay, I either must start taking drugs, or if I already have but forgotten, I should stop. A car chase in a motion picture film appears to have a continuous trajectory, or continuous motion, but is in actuality composed of individual discontinuous frames of movement. Simple.
In case you didn't notice I agree with this assertion/metaphor.
Ah drugs...
Both, yet neither either entirely.
Yep, you're definitely using...
Now this one really had me reaching for the drug cabinet (only problem is forgot I don't do drugs, or have a cabinet full of them ... damn!).
Because this is a false statement. As quanta have no empirical reality
When you quote, please try to be honest and present accurately my words as I wrote:
As quanta have no empirical reality (if one accepts quantum mechanics to best describe reality),
And I don't accept QM to best describe reality.
# That which is Known (fact, finite, discrete and measured) is observed or verified via time-delayed perception (physical senses). Thus, all that is Known (fact, finite, physical and real) is embedded in the Past.
Agreed
# We can never quite get to see, hear, smell, touch or taste the immediate now moment. In literal terms, it is immeasurable. The immediate now-moment, by being immeasurable is thus Unknowable.
No. You just proved (as I did in another thread on
'time') that Present is non-existing. Not unknowable.
# The Known physical world of things and facts is, and will remain, an after-effect of some Unknowable (Immeasurable and Unprovable) Cause. Ipso facto, science will not find the root Cause for (or be able to fully control) physical phenomena, facts or events.
This is a non sequitur. Your premises (the 2nd being partly invalid) don't imply this conclusion.
It's not because the Cause is a past event (it has amways been the case by definition) that it doesn't exist.
On the contrary that's what makes it a
provable and knowable fact!
You say it yourself in your first 'premise':
all that is Known (fact, finite, physical and real) is embedded in the Past
Must be the drugs...
There is no ontological argumentaton here just false assertion, self-contradiction and (bad) rhetoric again...
You do realise that quantum physics (according to one eminent physicist) is actual philosophy
I do, that's why I speak of the ontological consequences of such 'theory' and counter-argue it at a philosophical level using logic.
Anyway, continuum-space-time is NOT the corner-stone of Newtonian/classical physics.
... uhm, err, golly, right, so if Newtonian mechanics is entirely based on the assumption of perfection continuity, but such continuity doesn't physically exist, then, so, uhm err what are you actually suggesting?
Newton's laws of motion are three physical laws that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries,[1] and can be summarised as follows:
1.First Law: Every body remains in a state of rest or uniform motion (constant velocity) unless it is acted upon by an external unbalanced force. [2][3][4] This means that in the absence of a non-zero net force, the center of mass of a body either remains at rest, or moves at a constant speed in a straight line.
2.Second Law: A body of mass m subject to a force F undergoes an acceleration a that has the same direction as the force and a magnitude that is directly proportional to the force and inversely proportional to the mass, i.e., F = ma. Alternatively, the total force applied on a body is equal to the time derivative of linear momentum of the body.
3.Third Law: The mutual forces of action and reaction between two bodies are equal, opposite and collinear. This means that whenever a first body exerts a force F on a second body, the second body exerts a force −F on the first body. F and −F are equal in magnitude and opposite in direction. This law is sometimes referred to as the action-reaction law, with F called the "action" and −F the "reaction".
