    On the other side of things, I like to mention proton-pumps -- proton transfer is a big part of biochem, and the reason they work is cuz of quantum properties -- this event may not have transferred the proton, but the next one may not or will, and so on. The probability distribution of position/momentum is what makes the transfer happen.

    (This especially with respect to the notion that D2O is H2O -- the extra weight of that neutron is what makes it deadly to us)

    Heh, I wasn't, so thanks for highlighting what I ought focus on when I'm in the mood to focus fr fr.
  • What is real? How do we know what is real?
    I actually think you've ignored that sort of question over and over throughout this conversation. You are ignoring requests for clarity.Leontiskos

    M'kay.

    I'll focus on those, though not today. I've been responding with my first thoughts rather than digging in. Sorry if that's distracting.
  • What is real? How do we know what is real?
    I think the essentialist would tend to say the concept of fire (the understanding in the mind actualized by fire being experienced through the senses) stays the same, but our intentions towards it are clarified. Fire hasn't changed, but our intellects have become more adequate to it, and towards its relationship with other things. The identity of water as H2O clarifies a whole host of relations between water and other things (the way water acts in the world), and it is through those interactions that things are epistemically accessible at all.Count Timothy von Icarus

    Fair.

    Tho this gets a bit into some of my disagreements -- an essentialist has to have an idea of mind? Intentions, actualized understanding, experience through the senses?

    A Jedi craves not these things. ;)

    I suppose one challenge to the essentialist lies in pursuing the primacy of interaction into something like a process metaphysics, dissolving the thing-ness (substance) of water into processes. Yet this has its own difficulties.Count Timothy von Icarus

    Yeh, I'm not so keen on process metaphysics, though I ought to be given my stances.

    What can I say? I just live in a world of confusion and questions. :D
  • What is real? How do we know what is real?
    Why? Klima's whole point is that what Lavoisier & co. discovered does not falsify what came before. That Lavoisier understood water better than Aristotle does not mean Aristotle had no understanding of water, or that Aristotle's understanding of water was false.Leontiskos

    Because Aristotle believed water to have a teleology which put it above Earth, and air above water, and fire above air. The reason water goes where it goes is because it's supposed to be -- it wants -- to sit atop earth.

    At the time I think that's pretty much true -- how else to distinguish why the ocean sits on top of the land and we breath what's above the water and see the fire in the sky?

    I agree that Lavoisier did not falsify Aristotle. I just don't think there's a better or worse understanding of water with respect to historical thinkers.

    Today we'd say that Lavoisier had a "better" understanding than Aristotle, but tomorrow we may say the opposite if we find out teleology was right after all.
  • What is real? How do we know what is real?
    I disagree, but also I don't think it matters that I disagree because I clearly put them forward thinking them convincing :D

    When they are not.

    1a. The essentialist would say that the term “water” signified H2O before 19th century chemistry.Leontiskos

    I don't think that's what the essentialist would claim -- but I would claim that water was not H2O before Lavoisier. But this is a claim about meanings and how we understand things rather than the world. The essentialist would agree with me there, and the disagreement would be about true reference -- that when Aristotle described water without use of H2O he said true things about water which are no longer true today.
  • Does the Principle of Sufficient Reason imply Determinism?
    I like the example of a quarter because it takes it out of the realm of abstract science and into the realm of our everyday understanding.

    I'd use Yahtzee and Pachinko interchangeably with that example.

    All of them can be interpreted as being in a deterministic world -- where this very coin flip must be heads -- but that interpretation, so I think, is beyond our ability to judge things true or false.

    Rather, we have some macroscopic events which behave in accord with probability. And also some microscopic ones that surprised us along the way.
  • Does the Principle of Sufficient Reason imply Determinism?
    Heh, maybe.

    I don't think I'd be wise enough to be able to tell if indeterminism comes after determinism, or elsewise.

    What I know is that you have to perform the experiment in order to find out the outcome -- much like a quarter.
  • Does the Principle of Sufficient Reason imply Determinism?
    There's no question it's deterministicflannel jesus

    Well, I for one have a question -- namely that it uses probablity and you have to do the experiment to find out which "world" you happen to be in.

    I prefer the Copenhagen interpretation. No infinite worlds, but simply a probability in one world. But probability throws a wrench into the notion that every event is connected by necessity -- which is what I think of when I think of determinism.
  • What is real? How do we know what is real?
    If it's not relying upon the science then apparently Kripke would have made the exact same argument in 1700, before the science had occurred. Is that your claim?Leontiskos

    Seems a bit outlandish, so I certainly couldn't claim that.

    But I'd put it in historicist terms -- we can imagine Kripke being transplanted to another time with different concepts being taken seriously, but really we couldn't claim what he'd claim at that time at all. He was in his time, and made the claims he did in his time.

    Hrmm... if so then I've done so without meaning to.

    I'm still committed to essentialism being 1.

    1. The essentialist would be likely to say that water is H2O (or that water is always H2O).Leontiskos

    And I'd attribute a misunderstanding on my part of what you're looking for -- I thought I was cogently arguing for my point rather than it having three different meanings.
  • Does the Principle of Sufficient Reason imply Determinism?
    this conservation isn't about if its true. You expressed confusion about why people think many worlds is deterministic. Regardless of if it's true or not, you can hopefully be able to gain an understanding of why it's a deterministic world view.flannel jesus

    OK, got it.

    I thought you were claiming it rather than saying there's a possible interpretation of the equation such that determinism is true.
  • Does the Principle of Sufficient Reason imply Determinism?
    Have you googled if it's deterministic? What does a bit of googling tell you?flannel jesus

    Heh, no. In school I solved the Schrodinger equation in the one and only case that it's analytic as an exercise -- one proton and one electron.

    So rather than googling I'm drawing upon my studies from whenever ago. (and it might sound impressive, but really it's just a partial differential equation -- so if you know them maths you can solve it too)

    a deterministic function is a function that gives the same output given the same inputflannel jesus

    If so then sure it's deterministic, but with a probablistic mathematics which makes it such that you cannot tell what will necessarily happen.
  • What is real? How do we know what is real?
    Well, here the "is" is open to interpretation. D2O isn't called water; it's called heavy water, which is meant to remind us of the family connection with what we do call water. We can, and do, also call it deuterium, with no reference to "water" at all. The Kripkean approach is, I think, intended to help us distinguish between which "is" questions are about essences, or properties like "potability," and which are about uses of words. Another way of saying this:J

    Huh, that's interesting.

    I'd be inclined to say "potability" is, in large parts, what people mean by "water", though not always. In a way this is just a choice on how to use "water", from my perspective. We can include D2O or exclude D2O insofar that we understand one another.

    Which might put a spanner into Kripke. Point 1 about how "if water is H2O" -- it's not, if we include D2O, for instance. Unless we say that D2O is just a name for a variant of water, and it has 2 hydrogen molecules after all, with a little extra.
  • Does the Principle of Sufficient Reason imply Determinism?
    The Schrodinger equation is not deterministic, by my understanding -- unless probability distributions as events are somehow deterministic, but that seems to go against anything I understand of determinism.
  • Does the Principle of Sufficient Reason imply Determinism?
    You understand that the Schrödinger equation is deterministic tight? And that many worlds is just the idea that the Schrödinger equation continues to evolve the wave function with no collapse?flannel jesus

    I understand that it's not deterministic, but that's probably contributing to our misunderstandings.
  • Does the Principle of Sufficient Reason imply Determinism?
    Well, you can't, you see -- that's what I'm getting at. We can say these things, but there's no way of telling which is what -- why am I in the up and not the down universe? -- so the ontology is exploded beyond our ability to judge.
  • What is real? How do we know what is real?
    It's a point about how there are a posteriori necessary truths -- it doesn't say that water is H2O; it's not relying upon the science for its point. Only if water is H2O then it is necessarily H2O, and this was a process of discovery from terms we previously would not have associated with H2O.

    I think I'd push against the notion that D2O is water, after all, because it's not potable. Basically the "D" is a lot more different from "H" even though the only difference is the addition of a neutron.
  • What is real? How do we know what is real?
    I don't think he hopes to apply it to reality as much as he's making a point about logic.

    It's a subtle point, but he wasn't talking about reality as much as how we talk about reality -- logic.
  • What is real? How do we know what is real?
    The claim that "water is H2O" is not some philosophical conspiracy theory.Leontiskos

    To be fair to -- I didn't think he was claiming a conspiracy theory as much as thinking that philosophers make this claim because scientists have made this claim for a long time and they do it to bolster themselves with science.

    I don't think this is a good way to do philosophy, or what most people do in philosophy -- but he wasn't claiming a conspiracy theory as much as speaking a false assumption.
  • What is real? How do we know what is real?
    I (mostly) agree.

    the last bit I disagree with. Where you say:

    This whole idea “Water is H2O” is a sorry attempt by particular philosophers to gain some credibility from science to demonstrate how their theories have some sort of application to reality.Richard B

    I don't think that's true, because philosophers have no need of gaining credibility from the sciences -- except where the sciences are valorized and we must make proposals to say why our work will cure cancer, or whatever.

    Where I agree -- "Water is H2O" is false in the strict sense, as you've noted -- it has various other chemicals in it and yet is still water.
  • What is real? How do we know what is real?
    If it's a strawman then I must do the reading until I respond for reals.

    Given my commitments I'm not doing it anytime soon, but I'll stop responding as if I know something since I haven't done the reading.
  • What is real? How do we know what is real?
    Just brushing over the last 3 pages: Modern science can be integrated into the Aristotelian framework, of course.

    I'm still sensing the same transcendental error though: interpreting others such that they have to mean "x" (in this case x = essence) because else they'd fall into incoherence, and here are the reasons why they really mean "x".

    I can certainly see the Aristotle in our modern science, especially if I'm giving the with-the-grain interpretations of Aristotle.

    But...

    So water was not H2O before chemistry became popular?Leontiskos

    Yes, that's what I think. "water" nor "H2O" -- to use a phrase from your paper that I've only glanced at -- "pick out" what water or H2O is.
  • What is real? How do we know what is real?
    Specifically, if you disagree, then when will water not be H2O?Leontiskos

    When we don't have that level of description -- namely, before chemistry became popular. In Aristotle "water" does not mean H2O, for example -- it's just one of the five elements.

    I've started to think that Plato's ironic stance on philosophy is more correct than Aristotle's scientific stance, tho. In scientific terms I'd only be able to say that water will not be H2O if we manage to find another way to cut nature up that's more useful than the periodic table.
  • Does the Principle of Sufficient Reason imply Determinism?
    Are you sure that's the answer? Doesn't that pre suppose that you have some kind of pre-existent identity with which to flip heads?flannel jesus

    I don't think so -- and obviously the stochastic process is more complex than flipping a quarter -- but I do think that I'm me and not you simply cuz that's how the world evolved, in the same manner that a quarter can be heads or tails before you flip, but after you have a determined token.

    The universe in which you're you and I'm me is identical to the universe in which I'm you and you're me - so identical in fact that I posit it's most likely correct to say that the very concept that I could be you and you could be me is probably incoherent.flannel jesus

    Why would we believe this? It seems to me that there's a very salient difference between those universes -- namely that I'd be typing what you've been typing, and vice-versa.
  • What is real? How do we know what is real?
    Cool. I'll be honest in saying I don't think I'll be reading these anytime soon, but she looks interesting to me -- I like the notion that the medievals are good or better in various ways, I'm only skeptical because I think the attraction is a Romantic one: for a time that never was.

    I think I can characterize what is meant by an essence, which is why I'm anti-essentialist -- I'm against this particular rendition and various other possible renditions that basically fit. I'd say "essence" is what makes an entity what it is: water can be wet or solid, but it will always be H2O, for instance.
  • What is real? How do we know what is real?
    Nutty TPFers like to inveigh against essences, but they are all essentialists. They log off and immediately start talking about dogs, trees, cars, water, etc.Leontiskos

    :D

    Sounds to me like a transcendental error -- if they speak in this way, with nouns and such and believe it's true, then they must believe in essences even while proclaiming that they do not.

    Aristotle was forging something which was in competition with the theories of other ancient philosophers.Leontiskos

    He was, true. His philosophy is a deep and original contribution to the practice, even with our ability to read him only through his lecture notes.
  • Does the Principle of Sufficient Reason imply Determinism?
    That's an indexical problem. The answer to that is not a problem for many worlds, it's a problem for ANY multi-consciouness existence, even if many worlds is not true. Why are you you and not me? If you can answer that question coherently, you can also answer why you're this version of you in MWI and not some other version of you.flannel jesus

    I'm me and not you cuz there was a percentage chance I was you, and a percentage chance I was me -- and I just happened to flip heads.
  • Does the Principle of Sufficient Reason imply Determinism?
    we're not talking about if many worlds is true or not, just what the consequences of it would be and why it's considered deterministic. Right? You can understand why many worlds is deterministic separately from questioning if it's true or not.flannel jesus

    You may be able to, but I cannot understand why Many Worlds is deterministic for the reason I said -- why am I in the up-world and not the down-world? What is the deterministic law that makes it such that I experience this world I am in?

    We can make up one, but our experience is such that we get a probability distribution -- we might be in the up- or down- world, but we have to perform the experiment to see which we're in.

    And if we're in the up-world, what does positing a down-world we're not a part of do? Doesn't that explode our ontology beyond our ability to judge true or false? There may be a left-world, for instance, but we have only observed up- and down- quarks.
  • Does the Principle of Sufficient Reason imply Determinism?
    Heh. I suppose we just see probability differently then -- your dice example reminded me of my quarter example, but whereas you want many worlds to explain the actual results I'd just say that this is the nature of dice, quarters, or other trivia wanting more explanation than we are warranted in believing.
  • Does the Principle of Sufficient Reason imply Determinism?
    I'm not sure -- but I am certain that analogies between computer programs and reality are basically misleading, at least in our day and age.

    More directly: I don't think any of the executions of a program are deterministic, but are manufactured such that they appear, or are mostly, deterministic.

    So my skepticism of determinism, more than the PSR, is my motivation here.

    After all, it does the same thing every time.flannel jesus

    "does the same thing every time" isn't what I said with respect to different kinds of events.
  • Does the Principle of Sufficient Reason imply Determinism?
    I think it's a bit silly, but in the same way my question about universe 1/2 is silly. Not bad or wrong but a bit outlandish, is all I mean there.


    I'm struggling to see how many-worlds can be interpreted as deterministic, but again it seems like we're coming back to terminology in the first place.

    To wrap back around to your OP:
    There seems to be a common intuition, but not a universal one, that the Principle of Sufficient Reason, if it were true, would imply Determinism is also true.flannel jesus

    Where do you fall on the question?
  • Does the Principle of Sufficient Reason imply Determinism?
    I wasn't making a statement about our universe, you asked me for a scenario in which something would be true. It's a hypothetical to answer your question.flannel jesus

    Mkay.

    But qm is only a counter example depending on interpretation - you brought up many worlds, many worlds is deterministicflannel jesus

    Wouldn't we be able to ask "Why am I in universe 1 rather than universe 2?"

    ?

    Is there an answer to that question in the many-worlds interpretation?
  • What is real? How do we know what is real?
    Adorno said that whatever concepts Husserl came up with, from start to finish it was all so much idealist and reified paraphernalia (he took him seriously though, so I don't want to suggest a dismissive attitude on Adorno's part).Jamal

    I'll cap it there for tonight. I can't say either way, but the idea makes me smile cuz it makes sense -- tho I suspect I could find a point of disagreement along the way.
  • What is real? How do we know what is real?
    Given what we're reading -- I can excuse it because Husserl was before Auschwitz, and even suffered due to a certain H. turning him into the Nazi party.

    I poke fun at Husserl cuz I get irritated with him, but I ought not cuz any of us who take modern phenomenology seriously owe a debt to him.
