    If we from the scenario derive a logical contradiction then that scenario is logically impossible.
    Therefore it’s also metaphysically impossible.
    The dubious step is in generalizing to a whole class of scenarios. If the paradox can only be shown in a few representatives of the class then the the logical impossibility and metaphysical possibility of the whole class is only as strong as the generalization.

    In the square circle example, it's always the same scenario. We are just making clear on our definition.
    If your participant blocks one of your moves he is simply disagreeing with you on definitions. Fair enough, maybe a square means something different than a thing with four corners to him. You can leave the discussion simply disagreeing on what the word square means.
    In the grim reaper scenario we have different scenarios in each step so when objecting the disagreement is real and not simply definitional. We can't go away saying we simply disagree what a grim reaper or infinite or Bob means.

    @alexanderdelaney3978 3 ปีที่แล้ว

    Do I have this right? : Josh has a problem using UPD as a way to account for apparent paradoxes in GR scenarios because the reapers in most GR scenarios don’t explicitly follow the logical rule of the biconditional (which would make a scenario with such reapers logically impossible to create), but instead take action based on the current state of some object (e.g., Fred), and thus some mysterious force is needed to explain why the reapers can’t do their job. If that’s correct, then I can understand his concern. However, it seems to me that all scenarios of this type don’t actually contain inherent paradoxes anyway. (It’s only when contradiction-causing assumptions are made that paradoxes arise.) Perhaps it's worthwhile considering that possibility.

    What does it mean for an interval of time or a causal event to be infinitely divisible but not infinitely divided? (In Rasmussen’s blog.)
    Also, what exactly is an event? A substance instantiating some property at some time (to my ears, that sounds more like a state)? A change across time in the properties of something?

    • @andrejuthe
      @andrejuthe 3 ปีที่แล้ว +1

      First question: it is the difference between a potential infinity and an actual infinite. If continuuism is true the you can divide an interval into an infinite amount of points (i.e it is infinitely divisible). Second question: Events are states changing into other states; they are "occurants", they *take up time* and have different stages. By contrast, objects are enduring "continuans" they are *in* time persisting through time and *occupy* space. Objects can be moved whereas events cannot etc. An object can be part of an event, or be affected by an event but it makes no sense to say that an event is part of an object or that an event is affected by an object. A substance is something different from both properties and events; they are particulars that are bearer of properties. Substances can undergo events (like acquiring or loosing a property) or be affected by events (like when a tree is crushed by a tornado etc).

    In order to get from an infinite past to the grim reaper paradox, you'd have to apply the recombination principle over an infinite number of things (you'd have to go from saying it's possible that there is one grim reaper to saying it's possible there could be an infinite amount of grim reapers). I don't think this application of the recombination principle is any more legitimate than doing the same from a finite past and saying that if one grim reaper is possible in a finite past then it follows that an infinite amount of grim reapers are possible in a finite past.

      Hi! I'm not an expert but I'll give it a go.
      Recombination principle - the idea that if you mix individually possible things together in a hypothetical scenario, you end up with a possible scenario.
      Why it favours finitism - the grim reaper scenario is meant to show that from a mix of apparently individually possible things, you end up with an impossible scenario. So (accepting the principle of recombination) one of those individual things cannot really have been possible. It's proposed that the individually impossible thing is the assumption of an infinite past (or sequence) in the grim reaper scenario.

      Thanks a lot.
      May I inquire about two things?

      2- what gives the recompination principle its weight?

    • @HeyHeyHarmonicaLuke
      @HeyHeyHarmonicaLuke 3 ปีที่แล้ว +1

      (1) It's very hard to argue that it's the infinite sequence causing the impossibility, I haven't seen a really good attempt. Rasmussen is taking the finitist position in this discussion. Alex Malpass is arguing it might as well be the scenario itself, with rebuttals like the 'incompatible pair diagnosis'.
      (2) Intuition, I think. I don't have a good understanding of it, but what I outlined for the recombination principle is a slightly incomplete and naive version - people who hold to it still recognize that you can combine 'I am taller than you' and 'you are taller than me', and get to impossibility from recombining those possible individual things.
      So (and I think there are a few different ways this is cached out), it has a clause like, 'as long as you add them in consistent ways'.
      If you add individually possible things together _in a consistent way,_ you end up with a possible scenario.
      With that added clarification, it's just meant to seem right, intuitively. We are to think ~'That seems to be what I do in my head to generate possible scenarios all the time, and I can't see how anything could be a relevant obstacle as long as I stay consistent.'

      I don't think we should, but this video has a lot of Rasmussen arguing that we should. He feels like the underdog here though, with Malpass having more experience thinking about it, and why we shouldn't blame one of the pairs like that. :) :)

    The problem of squaring the circle is about whether you can with ruler and compass construct a line whose length is the square root of pie and thus constucut a square whose area is pie. It is by no means obvious that the square root of pie is not a constructable number, given that pie is constructable and the square roots of integers are constructable. I felt sorry for Joe: He had to listen to these guys butcher the problem of squaring the circle for nearly two hours. One of them even said it was obviously impossible (So obvious it was not "solved " until the 1800s (even with the likes of Euler being aware of the problem)). They made it seem like you had to smoosh two shapes together. Joe is TOO kind sometimes.

A philosopher does a lot of work and comes up with a paradox that rules out one of the five infinite ones. And then concludes that the universe is probably one of the finite ones.

      That being said, I agree with Malpass that it's better to run an example like the date machines spread evenly throughout time, which is exactly what Rob Koons does (quite successfully, in my opinion) with the Grim Messengers.

      Fair enough. May I ask what your thoughts are on the Grim Messenger version that Robert Koons has been writing about? Basically, each Messenger is set to write its current date as long as no previous day's Messenger has already written one. As of today, there must be a number on the page (either of a previous Messenger or today's date), but there is no number that could possibly be written on it if the past is infinite.
      At the end of the day, these are just intuition pumps. There really is no need for all the stories and analogies; they're just meant to draw out the absurdity. But the incoherence of saying "the sequence is such that it can never finish, and yet it just finished" is already rather obvious to me. I mean "infinite" literally means "cannot ever finish" or "having no end" (just look at the etymology of the term). And yet the present is, by definition, the end of the sequence of past events!

    • @HyperFocusMarshmallow
      @HyperFocusMarshmallow 3 ปีที่แล้ว

      @@Mentat1231 I don’t think it’s bringing out a paradox with infinite pasts. There are models with infinite past where you couldn’t even construct the grim messenger paradox , for example if there is a limit to the possible message length. There are also lots of models where time isn’t something that’s ticking but rather all of space time is some structure and it could just be that inconsistent histories don’t exist etc. there are so many ways out of that particular though experiment it’s not even funny. I think the rule in the grim messenger paradox is way more problematic than infinity. Imagine if you are a person believing the experiment has been performed in the past, you open the message and you see some number representing some day in the past (never mind how to even distinguish an infinite number of possibilities for a finite little human). You are confused, if you get a number you realize that the day before should have written their number. So you conclude that the experiment has not been performed as you believed. So the world is not paradoxical but the past may still be infinite. If you see nothing, you’ll think pretty much the same thing. If you instead see “don’t play with grim messengers” written you take the hint. There is nothing that you could observe that would make you believe the experiment has been performed and the world is now contradictory. But infinite past with a grim messenger past might be contradictory as a combination like the square circle example squares are not contradictory and neither are circles. The combination though. That’s enough.

    jlmartin.ku.edu/~jlmartin/courses/math410-S09/cantor.pdf
    Again, Cantor solved a very big contradiction in math. But Russell always loved to delight in paradox and as a result people today influenced by him still think these ideas are baffling when in actuality denying actual infinities causes the whole of mathematics to collapse. Do you believe that division is possible and indefinitely so? Then you agree that completed infinities are valid. Period.

    This topic needs more discussion!
    Linear casual finitism postulates multiple events (change) where the set of all contingent events are ontologically dependent on a necessary first event. Thus, within a cyclical finite chain, there could be vicious circularity and a bootstrap paradox. To argue events are ontologically dependent, one should rule out a conceptual theory of time, where change is an illusion (mind dependent divisions of a single event which is itself ontologically independent). Where the event represents the chain. Causation/ Becoming can be an illusion (see Parmenides). Being/Existence doesnt change. Existence cannot become nonexistence, the same way nonexistence cannot become existence.
    Josh is also wrong to combine two logically incompatible propositions to disprove metaphysical possibility of causal infinitism.
    Also, there is no infinite past on a cyclical chain. There is no point on the chain that is past, present nor future. They are all simultaneous. The relational view is arbitrary. Im tired of apologists always saying an infinite beginningless past is impossible, it's a strawman.

    I'm an hour in and it's just killing me how badly we need a sprinkle of Wittgenstein here! If a string of words is incoherent or entails something incoherent, then that string of words cannot express a truth (it can't express anything!). That's why we have necessity of *either* the metaphysical or logical sort. As Swinburne has said many times, "metaphysical impossibility" is just fully-spelled-out logical impossibility (where the powers, properties, etc. of the things being discussed are all taken into account). This is not at tension with a branching view or "powers" view of modality; in fact it complements it very well (just read Pruss' book and consider the hybrid option at the end). But, Malpass needs to understand that mere "overlap" is not sufficient to call something metaphysically possible. The overlap needs to be consistent with the properties (specifically, the causal powers) of all the relevant entities. I could describe a branching overlap in which everything up to now is the same, but then I leap 100ft into the air unaided. It's a branching. It's an overlap. But it doesn't cohere with my causal powers, and so it is, when fully spelled out, incoherent.
    I say all this because the point of Grim Reaper/Messenger paradoxes is to show that there is a straightforward incoherence directly entailed by saying an actually infinite sequence has elapsed. I don't think Malpass has come to grips with the fact that that would rule out any metaphysical possibility of an infinite past being instantiated. If a string of words doesn't make sense, then adding "it is metaphysically possible that..." or "a modal branch could exist such that..." before that string of words doesn't help anything.
    On the other hand, I don't understand why Rasmussen is using an example that is so obviously relevantly different from the case of an infinite past, when he could just go with Koons' "Grim Messenger" version. Malpass basically handed him that as a replacement option, and I don't understand why Rasmussen won't just take it and run with it. The Grim Messenger paradox is a literal, straightforward contradiction entailed by nothing more than the causal infinity.

    • @MajestyofReason
      @MajestyofReason  3 ปีที่แล้ว +1

      Thanks! So, it's untrue to say that the contradiction is entailed by nothing more than causal infinity. Koons himself explicitly points out that he needs auxiliary theses like the intrinsicality of powers, modal patchwork principle/recombination principle, and the further stipulation that each causal node n of the infinite chain is such that property or condition P holds at n iff it holds nowhere causally prior to n. Pruss is also explicit that it is false that 'the contradiction is entailed by nothing more than the causal infinity'. If you're curious about why we need to add the further condition about some property P's holding at member m iff it holds nowhere before m, for any m, see my discussion with Alex here: th-cam.com/video/uoTMs-kMny4/w-d-xo.html

      It makes sense that you'd need that stipulation. I guess I was thinking of that as being akin to assuming the Messengers are literate and not confused about the day and so on. I was thinking it was part of what was unproblematically stipulated until the mere addition of causal infinity turns an unproblematic case into a contradiction. But, I'll keep looking into it. Thanks! And thanks for all the great content. I'm loving it.

    I don't think they clearly addressed the flaw in Josh's reasoning from logical to meta-physical. If you make metaphysically possible changes and reach a logical contradiction then that is also meta-physically impossible. However, if you make metaphysically impossible changes, then you can't say that it proves metaphysical impossibility. That is if you violate the more permissive limits then that applies to the less permissive, but if you make more permissive moves, then it no longer applies to the less permissive at all.

    This is what the Cam vs RR debate should have been honestly given how much of the argument hinges on this exact discussion. Some thoughts.
    1. I disagree with both Rasmussen and Malpass here.
    Rasmussen seems to want to slide from causal finitism to either "a finite past" or "a finite number of events". Neither of which is actually entailed by causal finitism.
    Malpass wants to boil down the paradox to a contradiction of a pair of premises. I disagree. The contradiction is a triple, or a trilemma, not a pair.
    2. On causal finitism
    In previous comment sections (this channel, RR's channel, CC's channel, etc.) I've laid out my "angel" solution for the Grim Reaper paradox and argued how it could be generalized with randomness to solve whole classes of paradoxes aside from that one. I don't feel like copy/pasting it again here.
    If my solution holds, then the following holds;
    i) Causal Finitism is true
    ii) There are an infinite number of reapers
    iii) There are an infinite number of angels
    iv) There are an infinite number of events
    So it is incorrect to think that Causal Finitism entails, in any capacity, that there is either a finite past, nor a finite number of events within the past.
    3. On the Unsatisfiable Pair
    The Grim Reaper paradox derives its contradiction from 3 components:
    A) An infinite number of reapers
    B) The Bernadette Rule
    C) The reapers are uninterrupted while A
    My angel solution allows both A and B (for both reapers and angels) only suspending C, which tells me the "no first member" rule is decomposable nontrivially into A and C.
    This means you can suspend A (finitism, which is what Rasmussen wants to hold), B (particularism) or C (causal finitism). I agree with Malpass that there is a contradiction here but it's not from an untangle-able pair but from a triple which you can untie with metaphysical commitments.
    But yeah this is a fun conversation and the level these debates should have been at all along.

      1. Yes the trilemma is A, B, C.
      2. Angel Solution:
      The Grim Reaper Paradox has the following rules:
      (i) Fred is alive at the beginning (agree)
      (ii) Fred can only be killed by a reaper (agree)
      (iii) Multiple reapers can't kill Fred simultaneously (agree)
      (iv) Once dead, Fred stays dead (will be altered)
      (v) There are an infinite number of reapers (agree)
      (vi) The Reaper Rule (agree)
      To modify (iv) I'm going to add an extra element to the Reaper Paradox called an Angel, and an Angel has the following properties:
      (I) Angels can be any subsequence of indices occupied by reapers, (i.e. angels replace or "move" reapers, they are not "outside" the reaper sequence).
      (II) An Angel will make Fred alive if Fred is not already alive, (just taking the same reaper rule and applying it to angels).
      (III) There can only be a finite number of sequential reapers, and a finite number of sequential angels at a time. In other words, the following rules apply:
      (i) Given a reaper, it is a finite number of indices away, in either direction, from an angel.
      (ii) Given an angel, it is a finite number of indices away, in either direction, from a reaper.
      Putting this together means that the infinite sequence can be organized like:
      ... -> (finite sequence of reapers) -> (finite sequence of angels) -> (finite sequence of reapers) -> ...
      Now, does this solve the paradox? Yes.
      Normally:
      1. Suppose at some index k, Fred is dead.
      2. This means that Fred is killed by some prior reaper.
      3. But in order for this prior reaper to kill Fred, Fred would have to be alive, meaning the reaper before IT would kill Fred, ad infinitum.
      C. Fred is never killed by a reaper because the previous one should have done it already.
      Now:
      1. Suppose at some index k, Fred is dead.
      2. This means hat Fred is killed by some prior reaper.
      3. The sequence of reapers with a reaper rule is finite before some angel appears.
      4. As of that Angel, Fred is alive, made alive by the first in the sequence of angels.
      C. the first reaper after the last angel kills Fred.
      Repeat for the case where Fred is alive.
      This rule basically flips the reaper paradox into a quasi-Thompson's lamp paradox where Fred alternates between alive and dead, however, we know he's alive at the beginning so that thwarts the Thompson's lamp question.
      3. I don't know about epistemic particularism. I'm more getting at the idea espoused by Pruss as a contender to Causal Finitism that maybe in each paradox, there's a particular rule within that paradox that's the problem and so you evaluate each particular paradox by its own particular circumstances to dissolve it.
      So for the Grim Reaper paradox, you could say something like:
      The paradox happens because of the way the reaper rule is set up. Why would it be that the reaper rule depends on previous reapers? Why can't we just say that at any time a reaper shows up, if Fred were to still be alive (for any reason or no reason) the reaper kills him? Boom paradox solved.
      1. Pick any index k.
      2. Suppose Fred is alive as of k.
      3. A reaper shows up at k and kills Fred.
      C. The end.
      If Fred is dead as of index k, great, some other reaper got him and it's none of our business which.
      There may, after all, be finite paradoxes with rules like the Bernadette variety that show up in, say, Kafka novels (although admittedly those rules usually end up in a circle and so wouldn't work well a sequence of buck passing). So one might have a suspicion that continuous buck-passing may be the problem simpliciter (I'll do X if someone else didn't already do X).
      4. to clarify this one, I think one can untie them, and their choice of which of the 3 rules to suspend comes with metaphysical commitments.
      So if you want to allow an uninterrupted sequence of reapers with a buck-passing rule, then you'd have finitism which has things to say about time and all sorts of other considerations, unavoidably. Finitism is a pretty strong commitment.
      If you want an infinite sequence of uninterrupted things (or more generally things that all causally relate to each other with no "gaps") then you're going to have to limit which kinds of rules you can say about those things, even if those rules make perfectly good sense for the Causal Finitist cases. That increases the work you have to do for each paradox you want to explain away, each rule possibly requiring different metaphysical assumptions to justify its disuse. Even extra if you want to use the infinite case to justify that it can't be used in the finite one.
      Finally, everyone agrees that Causal Finitism has commitments it makes (I don't agree that time is discrete for example, but there may be others).
