  • Does quantum physics say nothing is real?
    You start to argue about that? On what basis?god must be atheist

    On the basis that the examples you gave, e.g. "my spirit is green," are not metaphysical statements.
  • Does quantum physics say nothing is real?
    I think you might agree with this take I found:Darkneos

    Yes. I might quibble with one or two points, but that is generally consistent with how I see things. Where is it from?
  • Does quantum physics say nothing is real?
    What's an example you reach for to explain this idea? (This is Collingwood, right?)Srap Tasmaner

    Yes, Collingwood. Example - materialism, realism, physicalism, idealism, anti-realism, monism, dualism, solipsism, and all the other ontological isms are metaphysical positions. Determinism and free will are also. I don't know if Collingwood would agree with these examples or not, but he's dead so I can say what I want.

    I like the poem. It's simple, descriptive. Maybe a little sad. When I read it, I wanted to do this. Forgive me.

  • Does quantum physics say nothing is real?
    "My spirit is green." metaphysical claim.

    "My spirit is green and my spirit is not green." Metaphysical claim that is necessarily false.

    "My spirit is green or my spirit is not green. " Metaphysical claim that is necessarily true.

    @180 Proof says your statements are "conceptually incoherent." I say they are meaningless. I think we're both saying the same thing.
  • Does quantum physics say nothing is real?
    What?apokrisis

    My one unending, drum beating message for almost all the time I've been on the forum has been that metaphysical statements are not true or false. They have not truth value. They are only more or less useful in specific situations. I've written exactly that statement dozens of times in many different discussions.

    They are how we can even derive counterfactuals to test. They are the axiomatic basis of truth claims.apokrisis

    Agreed. Axioms are statements not subject to empirical verification. Thus they are not true or false.

    Interesting (I guess 'analytical') approach180 Proof

    Is it reductionist metaphysics? I wonder if I've overstated my case.
  • Does quantum physics say nothing is real?
    But just not at the metaphysics of being apparently. So why hang around these threads to tell folk that?apokrisis

    It's the world that's wonderful. I love metaphysics, but I see that it's just a bunch of stories people have made up to explain it to themselves. We get to choose the one that works best right now and right here. Why shouldn't I tell people how I see it.

    The logic of the dialectic is so strong, nothing escapes it. The desire to reject metaphysics is itself what must manifest metaphysics as the “other” which has been placed at the greatest possible distance.apokrisis

    I don't reject metaphysics at all. Along with epistemology it's the part of philosophy that interests me the most. As I've noted elsewhere, it represents the essence of intellectual self-awareness. I've said it dozens of times here on the forum - metaphysical claims have no truth value.

    What makes the above seem like a poem in the first place is: linebreaks, no punctuiation, rhythm and rhyme.

    The monotonous repetition of short declarative statements, the choppiness, changes the tone for me. Maybe less sad and more resigned.
  • Poem meaning
    I think I did find the basic experience you described -- the experience of being awoken from a gloomy day-dream. That clicked for me. And then upon reading what you shared I could see how the bird was playing a kind of joke -- and to set up a contrast between that joke and the sadness of gloomy daydreams. I liked you highlighting that for me because I could see it there on a second reading when I didn't on the first.Moliere

    Keeping in mind that this is my idiosyncratic experience. I think other people would get different feelings.

    I think that means you're wrong.frank

    I'm not surprised at your conclusion.
  • Poem meaning
    This is a bit of a cheat, but I want to repost something I wrote about a year ago in the "Metaphysics of Poetry" discussion. This is my attempt to give my idea of a description of the experience of reading a poem.

    I think that poetry doesn’t mean anything beyond the experience of reading it or listening to it. As an illustration, I’ll provide a description of my experience of a poem I really like. “Dust of Snow,” as always, Robert Frost.

    The way a crow
    Shook down on me
    The dust of snow
    From a hemlock tree

    Has given my heart
    A change of mood
    And saved some part
    Of a day I had rued.


    I really like this poem. First off - it’s really short. It was easy to memorize and when I quote it, people think I’m erudite. I tried to memorize “Two Tramps in Mud Time” once - nine stanzas, 72 lines. That didn’t turn out well. Also, it’s funny and Frost uses one of my favorite animals, no surprise, a crow. Not everyone sees the humor in the poem and I get that. I don’t know how idiosyncratic my reading is.

    First stanza. Light, amusing. Very visual. I can see the man walking through the woods after a snow. That’s something that happens regularly in Frost poems. The snow is deep. He’s wearing boots. I can see the tree with the crow sitting at the top. Hemlocks are dark green with short needles ranked on many short branchlets. If that's a word. I’ve seen crows in the tops of trees plenty of times. Sometimes one, sometimes five, sometimes more. They’re usually noisy. Rambunctious. Very social. They’re really smart. It was clear to me the first time I read this poem that the crow shook the snow down on the man on purpose. That image always makes me smile. Having snow fall down on me from a tree branch has happened to me plenty of times. I can feel it going down my neck. Annoying.

    Second stanza - More serious. Darker. It also makes me look back at the first stanza and think more about it. It seems like something has happened that the man regrets. So, he feels unhappy, sad, maybe guilty. It’s later in the day. Maybe he’s walking home afterwards or maybe he’s walking in the woods to think things over, brood, head down, not paying attention to where he’s going. And then the crow. He looks up. He sees the crow. He can see the crow looking down at him. He smiles. Maybe he laughs a little.

    Why does this change his mood. I can think of a couple of reasons. First, it makes him break out of his introspection and look around at the day, the woods. That’s happened to me plenty of times. You just shake your head and get on with things. There’s another way to think about it that I really like. I like to think that at the moment the crow and the man are looking at each other, there’s a recognition. The crow made a joke. They both know it’s funny. Maybe the crow would cackle a little. I guess not. Frost would have mentioned that. The crow should have cackled. It’s hard to brood when your dignity has been tweaked. When someone has seen you for what you are.

    As I said, this is not what the poem means. It is how it makes me feel. What it makes me see, think, feel. I don't expect anyone else to get the same things as I did or see it the same way.
  • Does quantum physics say nothing is real?
    There is no absolute space and time, so no, we don't live there.frank

    You and I see things differently. I doubt there's any middle ground in our views.
  • Poem meaning
    So I was reading you as restricting poetic meaning to the experience, rather than making a distinction between meaning and experience.Moliere

    You're right. In discussions like this, sometimes I say "art has no meaning" and sometimes I say "art has no meaning beyond the audience's experience." Those are similar but different statements, but I mixed them all up together in my posts here.
  • Does quantum physics say nothing is real?
    But your body and brain depend on being able to harness quantum chemistry. Life and mind start at the quasi-classical nanoscale of molecular machines where proteins can beat the classical odds by employing quantum tricks.apokrisis

    And the success of a cake recipe depends on chemical reactions which take place when you add heat to processed chemical and biological material. But I just want to eat a piece of cake. I know I sound flip, but I'm serious about this. When I'm figuring out how long a train takes to get from Preston MD to Cincinnati OH I don't need to think about relativity. That's a trick example. There is no rail service to Preston.

    I think you are just too dismissive of the quantum realm. It is how there could even be the classical realm as its “other”.apokrisis

    I'm not dismissive at all, at least not of the science. I am a bit dismissive about overcomplicating the metaphysics. I think you and I have a different understanding about the value and use of metaphysics. I guess that's metaphysics too, or maybe meta-metaphysics.

    It is crazy that nature even exists in one form. It is doubly crazy that a second form hatches emergently from that. It is triply crazy that even the quantum form has to be emergent - or at least that is an implication of the success of quantum field theory.

    So stand back and marvel of all that we have discovered - some of it only very recently.
    apokrisis

    I do. I marvel all the time.
  • Poem meaning
    And, if accepted, it would make your distinction between art and reality, as you've acknowledged, ultimately artificial.Hanover

    Maybe I've misunderstood. I wasn't discussing the distinction between art and reality. I was talking about the distinction between fictional, poetic, or artistic communication on the one hand and purely descriptive, technical, or explanatory communication on the other.
  • Poem meaning
    Oh... I thought we were disagreeing.
    — T Clark

    Well, we're not!

    So there!
    Moliere

    Well, good. I guess. But then when I read your ideas it does seem like we're disagreeing.

    So you would claim that "poetic meaning" in reference to "meaning" is more or less an equivocation, that these are actually separate things. Do I have you right?

    That is fine by me, because I'm also actually interested in the aesthetics of poetry unto itself -- and actually put this in aesthetics with the idea of exploring that more than the usual reductions, with the idea of it generating more shared thoughts to build from.

    And, even more than that, while I have this odd suspicion, it is just an odd suspicion. And it's a lot easier to talk about how poems work and how it is they mean or what it is they mean.
    Moliere

    I'm confused. You keep talking about poetic meaning, but I said poems, art in general, don't mean anything. How can we be agreeing.
  • Does quantum physics say nothing is real?
    Newton worked within a framework of absolute space and time that we now know isn't real.frank

    Except that 99.99999% of the time we do live within a framework of absolute space and time.

    QM says some of our assumptions about reality have to be wrong.frank

    QM says that things work differently at small scale than they do up here where we are.

    The first ontologists were doing speculative physics. The two have already melded. There is a kind of metaphysics which is just language on holiday. It's fun to follow its convoluted paths, but it's ultimately pointless. Science is almost never pointless, so we might draw a distinction between that pointless kind of metaphysics and science.frank

    As I wrote previously, for me, metaphysics and science are completely different things.
  • Poem meaning
    I agree with this, too.Moliere

    Oh... I thought we were disagreeing.

    they necessitate dialogue, an other, a community, a group. The poem comes alive in the collective witnessing of the poemMoliere

    I agree with this. There are worthwhile things to say about poetry, but I don't think meaning is one of them except in the fairly trivial sense of knowing what the poet is referring to. Example - In "Wild Grapes" by Robert Frost, it's good to know that "Leif the Lucky's German" refers to Leif Erickson's German foster father.

    I like to talk about what I experience when I read a poem. As I see it, that's different from it's meaning. From my point of view, most of the poem interpretations I've read are baloney. I do also like to talk about technical aspects of the poem - meter, rhyme, metaphor - and how they help me share the poet's experience. I don't think that's the same thing as meaning either.
  • Poem meaning
    My point is that all is metaphor and poetry.Hanover

    In “Surfaces and Essences: Analogy as the Fuel and Fire of Thinking” Douglas Hofstadter claims that all human thought is analogical. I've read similar views in other places too.
  • Does quantum physics say nothing is real?
    It's just not the case that something odd is happening at the small scale, but this has no bearing on the way we conceptualize the universe as a whole.frank

    One of the points I've beaten till it's black and blue is that metaphysics is not universal. We don't need a one-size-fits-all universal metaphysical foundation. For me, metaphysics should be applied piecemeal. It's a tool to help with thinking and understanding - a tool box. When you're doing reductionist science, maybe pull out the materialism and realism. When it's math, pull out the idealism. When you're trying to see how it all fits together, you might need holism or even mysticism.

    This isn't an idealism vs. realism debate. You're right that much of that debate takes place outside the realm of science, but that could very well change in the next century, so let's not imagine that we've reached the pinnacle of understanding. We haven't. We're just somewhere on the trail.frank

    As I understand it, metaphysics and science are different kinds of things. One is the ground, foundation, of the other, especially if we include epistemology in with the metaphysics. Given that view, metaphysics and science will never meld into each other.

    I agree we are nowhere near the pinnacle, if there even is one.
  • Poem meaning
    What distinguishes an artistic expression from your expression quoted above? What would a non-artistic expression be? If there is no distinction, then all is art.Hanover

    I don't consider myself a very artistic person. I've done a little fiction and poetry writing. I enjoy the process and I like some of the results, but it's not really my thing. I don't draw or paint, but I sometimes think in very vivid imagery. For me, that kind of thinking is exhilarating. I have had the thought that the distinction between art and non-art communication is artificial. All of it is about taking something from my mind and putting it in yours. But that's not a very interesting argument to make and I think there are some important distinctions.

    I guess the difference for me is that non-fiction, including the kind of stuff here on the forum, is about sharing knowledge, ideas, or skills. With art, it's about sharing the actual direct non-verbal experience. As I said, the argument can be made that is an artificial distinction.
  • Does quantum physics say nothing is real?
    Thanks. So you, Banno, and others come crowding on to these kinds of threads to show that you don’t take deep and interesting questions seriously. You know better because you haven’t learnt either the physics or the metaphysics. Ignorance of the subject matter becomes your trump card.

    C’mon. You can do better than that.
    apokrisis

    I think I've shown I do take interesting questions seriously and I am very interested in these questions. As I noted, though, I think the gee whiz gets in the way of the science and philosophy. "Gee whizz" is not metaphysics, but in QM, it is treated as if it were.

    Also, I didn't mean to include you among the dorks on the forum, although it came out that way. I have always thought of you, Fdrake, and Streetlight as the voices I can trust in math, science, and related philosophy.
  • Does quantum physics say nothing is real?
    It is the flat contradictions in the causality that creates the angst. Sure, you can take the epistemic or modelling perspective that says we simply construct the pragmatic story that captures sufficient truth at each level. So shut up and calculate.

    But this invokes an ontology of emergent properties. And so you are just moving the metaphysical questions back to that next grounding level.

    For example, you can get into the hierarchy theory debate about whether emergence is all about supervenience - so microstate realism about emergent macrostates - or instead the kind of Peircean holism that I always promote.

    So why is quantum reality nonlocal and classical reality local? Why is quantum reality indeterminate or vague, and classical reality definite or crisp? Is it just epistemic accident we arrived at such contrasting causal axioms, or is it instead the big clue that shows there is a directly reciprocal relation in which reality emerges from the manifestation of that causal dialectic.
    apokrisis

    To the extent I understand what you're talking about, it makes sense. I'm starting to get a feel for your description of how hierarchy's work - the idea of downward constraints and holism. But on the other hand, who cares? Sure, you do and I do and a bunch of other dorks do. Scientists and philosophers seem as confused about this as the low-lifes here on the forum. As I wrote, I think the taint of mystery and weirdness makes it harder for people to figure out what's up.

    I don't even disagree with anything you said. I guess I just place the emphasis differently. People should realize the world is the world, not what they think it is or want it to be. They should get used to it.
  • Does quantum physics say nothing is real?
    Have you noticed how folk tend to rely on this distinction as if it were an argument? I don't understand that. Ontology and epistemology are not like ought and is...

  • Does quantum physics say nothing is real?
    the mooted distinction between epistemology and ontologyBanno

    If you're saying the distinction made between epistemology and ontology is arbitrary and unnecessary, I agree. If you're saying something else, I don't know what it is.
  • Does quantum physics say nothing is real?
    There is an argument to be had there. We can build the subjective anthropomorphic view into our metaphysics.

    But how is that to be done in a way that simply doesn't serve to contradict all attempts by physics to then take the objective "view from nowhere" as its highly productive metaphysics? And what happens when that unreasonably effective route has to turn around and recover its own subjective point of departure?
    apokrisis

    I think I'm trying to address a different issue than you are. It bothers me when everybody, even scientists, keep saying that the quantum mechanics is weird. It's not weird. It's just how things work. Why would you expect events at scales of 10 or 15 orders of magnitude smaller than ours to act the same way they do up here?

    So, QM doesn't make the world weird. Apples are still apples and they still fall when you drop them and crunch when you chew them. Canada geese still honk and shit on your lawn. Nothing in your daily life get's any less real. There's no reason to get all excited.

    On the other hand, I recognize there is a need for a broader context. Once everybody chills out we can work that out. Focusing on the weirdness of the quantum world makes it harder to understand. You can see the effects of that in this discussion.

    That is how all the quantum mysticism arises. If the foundation is the human observer making measurements – regardless of whether it is with their wide bum, or a clock and ruler – then how does this "classical" picture account for whatever emergently leads to the collapse of the wavefunction?apokrisis

    I think it arises from people thinking that QM somehow undermines their experience of the world we see every day.

    Have you ever tried making sense of action and reaction as a symmetrically opposed pair of force vectors? Or is it only me that saw that as the answer to how rockets worked in a picture book when I was 7 years old and thought, hey, that's a completely bogus metaphysics!apokrisis

    The law of conservation of momentum always made sense to me, although I'm sure I wasn't aware of it when I was 7. Or Newton's laws either. I'm even more sure I didn't know what metaphysics is. You clearly were a prodigy.

    So you were on the nose with your earlier remark about scales of observation. But my point here is about taking the ontology seriously once you have indeed sorted out your epistemology.apokrisis

    As I said, I see the human scale standard as a convention. A place to stand while we take our measurements of phenomena much larger or smaller or much more or less energetic then where we grew up.
  • Does quantum physics say nothing is real?
    It is right that reality looks different at different scales of interaction. And so that makes us ask which scale is foundational and which is emergent.apokrisis

    As a matter of convention, I think it makes sense to think of interactions at human scale as foundational, at least for bookkeeping purposes. It was at that level that the whole concept of reality was established. It's at that level that most people experience reality directly. It's at that level where noting weird is going on.

  • Poem meaning
    In one sense an interpretation of a poem will set out what it means, why it's significant, the feelings that might arise,Moliere

    I've come to see that art, including poetry, doesn't mean anything beyond the audience's experience in seeing, reading, or hearing it. Art is an artists way of expressing an experience which makes it possible for them to share it with others.
  • How do we develop our conciousness and self-awareness?
    No. Learning is about memory, and memories are things one becomes aware of when something reminds one. Learning about learning is doubly so. I could put it this way; "Awareness is the present moment", and one can be aware of the past but not in the past. I remember being aware as I wrote that last sentence, that it would likely be confusing, and I am aware as I write this one that I may not be clarifying things much.unenlightened

    This point is probably not worth arguing about more than we have.
  • Does quantum physics say nothing is real?

    From the August 2022 edition of "Skeptical Inquirer." Thanks to @Gnomon for the quote.

    Let that sink in : there is no way to empirically tell apart different interpretations of quantum mechanics. One might even suspect that this isn't really science. It smells more like . . . metaphysics. — Massimo Pigliucci

    Pigliucci is a philosopher of science at City College of New York.
  • Does quantum physics say nothing is real?
    So what about the Wigner's friend experiment.Darkneos

    There are many interpretations of quantum mechanics. It is my understanding that there is no empirical way to determine which, if any, are correct, even in principle. Questions which can't be answered empirically are not science.
  • Is it possible to be morally wrong even if one is convinced to do the right thing?
    All decent people today (at least in so-called Western countries) agree that slavery is morally wrong, and that this is not just an opinion, but a moral fact. Most would even argue that slavery has always been wrong, be it 200, 400 or 2000 years ago.Matias

    I think many people knew even 200, 400, and 2,000 years ago that slavery was wrong. America's founders - Jefferson, Washington, Monroe, Madison - knew it was wrong or at least had serious doubts even though they owned slaves themselves. They knew their practice put the lie to their rhetoric in the Declaration of Independence. That doesn't answer your question, but I think it shines some light on it.
