  • Bell's Theorem
    It's a statement about what it means to be a "wave", how the concept indicated by that word is understood through normal human conventions, especially as it is used in the more specific physics of waves.

    So, if light exists as a wave, which much evidence indicates, then it exists according to the principles understood by the concept signified by "wave", which i was talking about in the statement. It is a simple conclusion of deductive logic. P1, Waves have x essential properties. P2 Light exists as waves. C Therefore light has X properties.

    Phenomena in the world are not constrained to behave in accordance with our definitions. Before Michelson-Morley, people did believe that a medium was required for a wave to propagate. It took them a while to be convinced otherwise. Your definition is 150 years out of date.

    Do you believe that light must have a medium in order to propagate as a wave? It doesn't.

  • Bell's Theorem
    It's not pseudoscience which I am engaged in, because I do not pretend to be doing science. I am speculating in metaphysics and not at all pretending to be doing physics.Metaphysician Undercover

    You wrote:

    I've studied enough physics to know that a wave is an activity of a substance. That's simply what a wave is, and all waves are understood through modeling the movement of the particles within that substance.Metaphysician Undercover

    This is not a metaphysical statement. In this context it's a statement about optics, the physics of light, and it's wrong.

    This is the key point, the attempt to detect "relative motion" of matter through the ether. If it is the case that matter as well as the waves are both properties of the ether, then there would be no such relative motion, what we perceive as matter would just be a moving part of the ether. And, this is supported by quantum field theory. Particles of matter are understood as properties of the field, not distinct from (so as to move relative to) the field.Metaphysician Undercover

    Again - this statement is at odds with the fundamental basis of modern physics.
  • Bell's Theorem
    The idea he's presenting here is that of quantum field theory if I understand him correctly - he did bring that up before. Quantum field theory is, by my understanding, far from pseudo science, though the comparison between quantum field theory and the aether *might* be - it seems like at least a fair comparison to think of, but I don't know enough to say why it's not.flannel jesus

    This from Wikipedia:

    In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics. QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of quasiparticles.Wikipedia - Quantum Field Theory

    QFT has nothing to do with the propagation of light. Propagation of light does not involve movement of particles within a substance. Saying that it does is wrong. It's not only merely wrong, it's really most sincerely wrong. How wrong does something have to be before it becomes pseudoscience?
  • The von Neumann–Wigner interpretation and the Fine Tuning Problem
    I'm not sure I understand what you are implying. That an observation (or perturbation) precedes the so-called "collapse" is not in question. But "correlation does not prove causation". In my quoted definition above, "The observer effect is the fact that observing a situation or phenomenon necessarily changes it". The crux of the controversy seems to lie in the difference between "observation" and "perturbation".Gnomon

    I'll say it again one more time and leave it at that. No... I won't say it again, I'll just copy my previous comment here:

    The possible role of observation in "collapsing the wavefunction" or whatever is a completely different phenomenon than the observer effect.T Clark
  • The von Neumann–Wigner interpretation and the Fine Tuning Problem
    True. Although given the ways we've already found that life has adapted to take advantage of quantum effects, I figure it will probably come to play some sort of role. Obviously life uses quantum phenomena in that all chemistry is quantum phenomena, but it seems likely that adaptations for molecule level cellular machinery taking advantage of non-classical effects will be something we continue to find. After all, live evolved in our real world, not the abstraction we call the "classical scale world," and if optimal solutions involve quantum effects then life could easily have chanced upon them over 4 billion years.Count Timothy von Icarus

    Of course life has adapted to take advantage of quantum effects. Natural selection operates on organism's interactions with the world. The world at a basic level includes quantum effects. The classical world emerges from the quantum world. Again, that says nothing specific or direct about consciousness.

    You already have neat little experiments like this: https://www.sciencealert.com/study-suggests-spins-of-brain-water-could-mean-our-minds-use-quantum-computation

    https://iopscience.iop.org/article/10.1088/2399-6528/ac94be

    There has been a decent trickle of these, some related to how microtubules and tubulins re-emit trapped light, etc.
    Count Timothy von Icarus

    I have no doubt that much of how an organism operates uses quantum mechanical effects.

  • Bell's Theorem
    The Michelson–Morley experiment was an attempt to measure the relative motion of the Earth and the luminiferous aether, a supposed medium permeating space that was thought to be the carrier of light waves. The experiment was performed between April and July 1887 by American physicists Albert A. Michelson and Edward W. Morley...

    The experiment compared the speed of light in perpendicular directions in an attempt to detect the relative motion of matter through the luminiferous aether ("aether wind"). The result was negative, in that Michelson and Morley found no significant difference between the speed of light in the direction of movement through the presumed aether, and the speed at right angles. This result is generally considered to be the first strong evidence against some aether theories, as well as initiating a line of research that eventually led to special relativity, which rules out motion against an aether."

  • Bell's Theorem
    I've studied enough physics to know that a wave is an activity of a substance. That's simply what a wave is, and all waves are understood through modeling the movement of the particles within that substance. That's what a wave is, a specific type of activity of a substance which involves an interaction of its particles. Therefore a wave in empty space is simply impossible because there would be no particles there to make the wave. Yet we know from observation, rainbows, and other refractions, that light must consist of waves, therefore there must be a substance there which is waving.
    — Metaphysician Undercover

    Ok, suppose space is the "substance there which is waving". After all, the gravitational wave observations in recent years, (combined with electromagnetic observations of the source of detected gravitational wave observations) provide some pretty good evidence for space waving.
    wonderer1

    What M-M disproved is that the relationship between massive objects, bodies, and the ether, is not as was hypothesized. That does not prove that there is no substance which is waving, it just proves that the relationship between massive objects and the substance which is waving, is not as they thought it ought to have been.Metaphysician Undercover

    This is completely at odds with the fundamental basis of modern physics. There's no legitimate physicist in the world who believes it. Light propagates without a medium. If you post this on a physics forum, it will be removed immediately. It's pseudoscience.

  • The von Neumann–Wigner interpretation and the Fine Tuning Problem
    Thus, the need for philosophical interpretation of spooky quantum results led phycisists to include the experimenter's subconscious preconceptions & intentions as a force to be reckoned with : The Observer Effect*1.Gnomon

    The possible role of observation in "collapsing the wavefunction" or whatever is a completely different phenomenon than the observer effect.

    "if quantum mechanics really does provide the most fundamental description of nature, then at some level it must incorporate an account of consciousness and other key mental properties".Gnomon

    That's exactly what I meant when I said

    I don't think quantum mechanics has any special understanding to add to the study of consciousness beyond it's role as the substrate for all physical phenomena.T Clark

    Quantum mechanics is a scientific theory. It describes aspects of our world. Our world includes consciousness. That doesn't mean there is a specific, direct connection between QM and consciousness.

After a few respectful responses, anything more is just giving him an audience. He knows his opinions are not popular and he comes looking for a fight.

  • Duty: An Open Letter on a Philosophy Forum
    The important point is that the motivator has personal a base, not a relation to something external like "duty".Metaphysician Undercover

    I agree with this.

    "Duty" is better described as a director of action rather than a motivator of action. A person with no sense of duty might still be highly motivated to act. So if you want to talk about "duty", you ought to be able to make this distinction, between being motivated to act, ambitious, and being directed in your actions by some sort of sense of duty. Then we could discuss how ambitions are directed. Accordingly, the following paragraph doesn't make much sense:Metaphysician Undercover

    I think the distinction you make between duty as a director rather than a motivator is a good one.
  • Duty: An Open Letter on a Philosophy Forum
    I think you guys misunderstandToothyMaw

    I think I do understand, but I disagree with what you wrote. As I noted, I don't think duty is the strongest motivator or even a particularly important one for many people. As for the rest of your formulation, sure, strong, loyal leaders are necessary, but I'm not as cynical about our system as you are.

    No. I don't see it as contradictory at all.
  • Duty: An Open Letter on a Philosophy Forum
    I contend that duty is perhaps the single strongest motivator for action I can think of, whether it is duty to the tribe, an ideal, a spouse, etc., and should be nurtured wherever it exists to good ends.ToothyMaw

    This is certainly not true of me. Motivation comes from inside. It comes from love, empathy, fear, hunger, hate, shame, guilt, friendship, fellow feeling, affection... Loyalty, responsibility, kindness grow out of love, friendship, affection. A desire to do good for people we care about. Duty, morality, judgment grow out of fear, guilt, shame. A desire to avoid the judgment of others.

    But verifiable experiments have been born from this sort of work. For example, tests of Bell's Inequalities came out of work in foundations and are important. The delayed choice quantum eraser experiment came out of Wheeler and Feynman's work in foundations.Count Timothy von Icarus

    One thing that Becker wrote and that I endorse is that, even if different interpretations can not be distinguished empirically, they have epistemological value if they can help suggest new ways to test quantum mechanical principles. If I remember correctly, Becker's statement was kind of arm waving and he didn't really provide any examples.

    I understand that phenomena at atomic and subatomic scales behave differently than those at human scale. It is common that phenomena at different scales behave differently.
