    Is metaphysics like physics, but cooler? Or is it a relic of an outdated, pre-empirical way of thinking about the world? Closer to the former than the latter. Rather than building specific quantitative theories about the world, metaphysics aims to get a handle on the basic logical structures that help us think about it. I talk with philosopher Katie Elliott on how metaphysics helps us think about questions like counterfactuals, possible worlds, time travel, mathematical equivalence, and whether everything happens for a reason.
    Katrina (Katie) Elliott received her Ph.D. in philosophy from the University of North Carolina, Chapel Hill. After being an assistant professor of philosophy at UCLA, she is now on the faculty at Brandeis. Her research covers topics in metaphysics and the philosophy of science, including explanation, chances, and the logic of time travel.

    The back and forth questioning between the host and guest should be encouraged in the future as it enhances the conversation a great deal. In that vein, I wonder if you could ask future guests ahead of time to come prepared with some questions for you related to your expertise/interests in physics and philosophy that possibly relate to their expertise. This was an interesting exchange.

      Agreed. I'd also like some more debate-focused episodes so that we could see some sharp but good natured debate between competing ideas. It might aid the audience's understanding and maybe even help us be better/nicer/more constructive human beings too.

    1:09:00 Blew my mind, that if you allow classic time travel, determinism and eternalism is necessary. Loved this talk. However doesn't entanglement with you in the environment and decoherence, in case of a quantum dice, change the outcome, and thus change the future? If this is not your conclusion which it isn't for both of you, doesn't this imply you think the Born rule is unaffected and thus time travel doesn't imply eternalism or determinism, but even more it implies superdeterminism in which the born rule is obsolete?

    I agree with Baas van Fraassen that it is unfortunate that metaphysics was exhumed during WVO Quine's time. I think Wittgenstein's and Carnap's attitude towards metaphysics is the most mature one: metaphysics is not directly about reality, but it's a discourse about language use (often about the use of the word "existence" in natural language or other types of language).

    I always feel like there’s something wrong with my brain compared to other people when I hear these kinds of thought experiments. Does the magical being have perfect (or near perfect) prediction powers? And is he looking into *my* brain and predicting what I am going to do based on what he sees in my brain?? Does he know I want a million dollars and I”m only going to pick one box and he’s going to put the million dollars in the opaque box for me? How does he decide what I am going to do?

    • @RobRoss
      @RobRoss 10 місяців тому

      P.S. I assume there’s some math involved that tells us that picking two boxes is “better.” Fine. But I am not going to make a rational decision here. I want a million dollars. I hope the being knows that and isn’t going to assume that I’m going to be rational just because I listen to podcasts like these.

    • @RobRoss
      @RobRoss 10 місяців тому

    Yes. Metaphysics, historically, is a solid field of knowledge. Important subject. Useful do demistify adulteration of the concept. 🙏Ethymology does not define the evolution of the field. Around scientific positivism era it has been diminished, middle ages have overrated it... We have at least 24 centuries of explaining to achieve.
    A relation between extended mereological simples and philosophy concepts of extended simple may be defined as?
    At 50%, grokking suggest a beautiful podcast. ✨

    Regarding time travel back to before you flipped the indeterministic coin. It seems to me that if you are about to re-flip that indeterministic coin and you think you can predict the outcome with 100% certainty, you’re implicitly admitting to some kind of “hidden variable theory” of the world. That is, you *could* have known the original outcome of the flip if you just had more information (Laplace’s demon.) But if QM is to be believed, this information simply does not exist. So in my mind, the coin flip should be allowed to come up differently. I’m a many-worlds guy, so I interpret this as there are two universes in which both outcomes obtain, and you are time-traveling back to a point before this branch occurred. (Of course this makes me question what are “you” that feels like you are experiencing only the single outcome of the coin flip. There should be another you somewhere else experiencing the other outcome. And both of you “feel” like you. But that’s an entirely different discussion.)

    'meta' is Greek for 'after', highlighting the fact that metaphysics necessarily follows physics, while physics itself follows nothing but the laws of nature, so that's a difference between them or a hierarchy among them.

    Here's the issue I have with two-boxer's in Newcomb's paradox. They get hung up on the 'magical being' aspect of the question. Replace that being with a smart person with access to the internet, and advanced warning of who is coming to the test. Do they REALLY think that that smart person could NOT determine which they were likely to choose? Most people who have heard of the question ANNOUNCE IN PUBLIC what they would do. Getting a 90% correct rate wouldn't be that hard. Writing an AI to do the search would get 95% at least. Given that, who gives up a 95% chance of $1,000,000 for a 5% chance of 1,000,100?
    As far as I can tell they are just virtue signaling that they don't believe in 'magical beings'.

    All you need to know about metaphysics is that "experts in the field" cannot even agree on what metaphysics is, what defines it, what problems it is to solve, nor how to go about solving them. Even worse, an individual metaphysician cannot seem to clearly state what their own person views on the above are without running around in metaphysical circles.

    Logic is based on the law of noncontradiction, which is a result from the Pauli exclusion principle being exposed to evolution, creating us thinking beings with the Pauli exclusion principle logged inside our brains: the law of non contradiction, which is the first law of thought. So if nature and natural law was different, thought would be different. Hence a metaphysics based on the law of noncontradiction is not fundamental, in a reality before the big bang is my opinion. My two cents

    Indeterminism is not compatible with Eternalism! One thing is to claim epistemic indeterminism to justify compatibility and quite another to absolutely posit the world can be undetermined and at the same time assume all Reality is finished and complete which includes all the future state of affairs. We are talking here about fundamental indeterminacy not epistemic indeterminacy which totally different!
    The Multiverse hypothesis doesn't change the picture at all!
    The fact that you don't know on which future Universe you will end up being when you are about to make a choice and haven't made up your mind yet is an Epistemic problem.
    A Multiverse where all possible state of affairs, all possible Universes exist is Deterministic period! If you don't like cause and effect in an Eternalist set use perfect correlation instead!
