Re: "Heuristic" Predictions
Let me preclude this reply with this:
You may have noticed that I haven't participated here in a month; I have been too busy. I now have some free time that I am going to spend explaining to you how my thinking differs from your's, as a constructive attempt. If you're going to prefer to be argumentative and bring up the same old shit and just re-say things that you already have, then I am going to not reply any more. M'kay?
I said that it is impossible to have ANY confidence in ANY prediction borne of ANY naturalistic explanation without implicitly assuming both the consistency of natural law and the absence of supernatural agents that will override those laws
I don't think this is true, and I think it is an error in inductive logic.
Take the observation that every crow that you've seen has been black. There would then be a scientific theory that all crows are black. This theory is not saying that there are no white crows that exist. That is the nature of inductive logic. That doesn't mean that you cannot have any confidence in the all crows are black theory, especially if it is working.
Now, scientific theories do not explicitly state the lack of the supernatural, nor do I think they implicitly imply it. They simply don't touch on it. If it works then sweet, we can just continue on with it and get more shit done.
In Message 263, you wrote:
I am holding my pen in the air again. I am going to let go.
  • What do you think my pen will do
  • How confident are you of this behaviour?
    Assuming that you do have confidence in the predicted behaviour of my dropped pen on what possible basis do you have this confidence if not in the consistency of natural law and the absence of any supernatural agents overriding these laws?
  • Of course we can have confidence that the pen will drop, and mass bending spacetime is the best explanation we have for that, and we can have confidence in that explanation. But this is not saying that, to be ridiculous, there are not undetecable angels dancing on the pen to make it drop. And it doesn't matter how many times you reproduce your result, that fits within your prediction, you are still not providing evidence that the angels are not there. But if your explanation works, then fuck the angels... nobody cares.
    We can have confidence that they aren't there, and our predictions will be met, all the while not having anything to say about whether or not those angels actually exist.
    So I ask you - Can we legitimately have confidence in conclusions and predictions made on the basis of consistent natural laws and the absence of any supernatural agents overriding those laws?
    Or are you still asserting that such assumptions are "heuristic" and statistically invalid?
    Yes we can have confidence in them, especially if they are working, but they are not statiscally, or logically, valid.
    I think I've brought this up before, and you didn't reply...
    What you are relying on is Inductive Probability:
    quote:
    It has often been noted that the word ‘probability’ is used in two different
    senses in ordinary language. In one sense, probability is relative
    to the available evidence and does not depend on unknown facts about
    the world; probability in this sense has something to do with inductive
    inference and so I will call it inductive probability. In the other sense,
    probability is a fact about the world and not relative to the available
    evidence; I will call this physical probability.
    As an illustration of the difference between these two concepts, suppose
    you have been told that a coin is either two-headed or two-tailed
    but you have no information about which it is. The coin is about to be
    tossed. What is the probability that it will land heads? There are two
    natural answers to this question:
    (i) 1/2.
    (ii) Either 0 or 1 but I do not know which.
    Answer (i) is natural if the question is taken to be about inductive
    probability, while (ii) is the natural answer if the question is taken to
    be about physical probability.
    I still think you are trying to take an inductive probability about the supernatural and assign it a physical probability and that this is where the error of your logic occurs.
    quote:
    Continuing with this example, suppose you now observe that the
    coin has a head on one side. Given the information you now have, the
    inductive probability of it landing heads on the next toss is 1. Thus
    the inductive probability has changed with the new evidence. You also
    now know that the physical probability of the coin landing heads is 1,
    but this probability has not changed, it was 1 before as well, only your
    knowledge about it has changed. This further illustrates how inductive
    probability is relative to evidence and physical probability is not.
    I also think that part of your error is in assuming that a scientific explanation acutally precludes a supernatural one, and you think that pretty much all the supernatural explanations have been refuted by scientific ones. I don't think this is true. Just like it doesn't matter how many times you drop your pen, you still haven't shown that the angels aren't there.
    Now, this doesn't mean that we cannot have confidence that the scientific explanation will work, it just means that inductice logic doesn't preclude an alternative. And I think this is what Bluejay was getting into with having something to compare it to. In the end, you're still just assuming that the supernatural doesn't exist. It isn't something that you're arriving at from the available evidence.

    Re: "Heuristic" Predictions
    Let's take this step by step.

    So we can have confidence in our naturalistic explanation because it has resulted in verifiable predictions. Good. We agree on that.
    Now if we are confident that gravitational effects are caused by by space-time curvature then we must correspondingly consider it unlikley that gravitational effects are caused by dancing angels. Do you agree?
    This is rather fundamental so an answer would be appreciated.
    CS writes:

    Except that this explanation is simply unable to make any verifiable predictions. And is thus unworthy of any confidence. In short it is unlikely to be a correct explanation as the cause of the observed phenomenon (gravitational effects in this case). No?
    CS writes:

    So according to your argument we are only ever talking about supernatural entities which are utterly imperceptible. Utterly imperceptible because they either play no causal role in any aspect of observable reality or they do so in a manner that is indistinguishable from natural law.
    Is that your position?

    Re: Confidence comes from comparison
    How confident are you that when I drop my pen it will simply fall to the floor?
    How confident are you that the entire universe was not created supernaturally in full (including our memories) two nanoseconds ago solely to make me look silly when I drop my pen, expect it to fall to the floor, and isntead watch in bewilderment as it flies out of the window?
    Is the above supernatural possibility falsified? No. Obviously not until I actually drop my pen.
    So on what comparison are you rejecting this supernatural possibility as pointlessly unlikely?
    Or am I wrong to have confidence in my pen simply falling to the floor?

    Re: Confidence comes from comparison
    Hi, Straggler.
    This whole time, you’ve been arguing from the position that you think I’m reasoning inconsistently. So, you keep demanding that I respond to various examples, thinking that, when I see what conclusions my arguments come to, I will suddenly decide that I don’t agree with it.
    Your reasoning for this is apparently that you personally find the conclusions nonsensical.
    But, I ask you, what reason do you have to believes that I will also find the conclusions nonsensical?
    I am aware of what conclusions my argument leads to, and I don’t have a problem with them.
    Straggler writes:
    How confident are you that when I drop my pen it will simply fall to the floor?
    Good grief, drop the gravity crap already!
    As far as I’m aware, there isn’t a clear naturalistic explanation for gravity yet, so this is hardly as analogous to the situation at hand as you seem to think it is.
    As far as can be told with present knowledge, gravity is supernatural.
    It is possible to have confidence that a pen will fall when I drop it.
    But, it is not possible to have confidence that the explanation for why the pen will fall when I drop it is naturalistic, because naturalism cannot be used to demonstrate its own veracity.
    This is the logical conclusion of my argument.
    I do not have any problems with this conclusion, and I don’t find it to be nonsensical. Furthermore, it doesn’t have the catastrophic effects on my ability to reason that you seem to think it would.
    -----
    Straggler writes:

    So on what comparison are you rejecting this supernatural possibility as pointlessly unlikely?
    I have made no such claim, and thus, do not have to provide the comparison on which I have made the claim.
    And, once again, I have already told you that scientific confidence is not robust to supernatural explanations.
    And, I have no problem with the ramifications of this position, which are neither as severe nor as melodramatic as you seem to think they are.
    Why do I have to keep saying this?
    Will you finally accept that this is, indeed, my position?
    Or, will you demand that I hold your hand and walk you through yet another example?
    If you’d like, we can go through every theory that currently exists in science, one at a time, and I can show you how to apply my reasoning to each of them, and describe for you what the conclusions will be. However, I think you are fully capable of doing that on your own if you actually apply my reasoning the way I’m explaining it to you.
    I am not afraid of the conclusions of my own reasoning, Straggler. So, please stop throwing out examples of the ramifications of my reasoning, because I am aware of them already, and you keep messing it up anyway.
    In particular, my argument never has the ramification that supernatural alternatives are confidently rejected. Stop presenting examples in which you think it does.

    No. I don't think so because I don't think it follows from the inductive logic, but I'm having trouble with this example. I can't imagine any observations of mass curving spacetime so I don't see how it rules out something like angels being responsible.
    Can you think of a better example?
    Except that this explanation is simply unable to make any verifiable predictions. And is thus unworthy of any confidence. In short it is unlikely to be a correct explanation as the cause of the observed phenomenon (gravitational effects in this case). No?
    No, something like that wouldn't follow from the inductive logic nor the observations. I see why you'd think that though.
    So according to your argument we are only ever talking about supernatural entities which are utterly imperceptible. Utterly imperceptible because they either play no causal role in any aspect of observable reality or they do so in a manner that is indistinguishable from natural law.
    Is that your position?
    Not necessarily, I just thought you wanted to limit it to those. I don't like limiting the supernatural to utterly imperceptible things because then were limited to things that are impossible to ever be observed.

    On what basis? Be specific.
    You haven't falsified the possibility that the universe was supernaturally created in it's entirety 2 nano-seconds ago and that our memories and expectations of gravitational law are nothing but false inserted experiences designed to fool us into expecting my pen to drop to the floor instead of shoot out of the window.
    According to your arguments any conclusion that unfalsified supernatural possibilities such as the above scenario are "very improbable" are heuristic, statistically invalid and unworthy of any confidence. So on what basis do you dismiss this scenario?

    Confidence.
    CS if we have confidence in space-time curvature as being the cause of gravitational effects how can we consider it anything other than unlikely that dancing angels are the cause of gravitational effects?
    CS writes:
    I can't imagine any observations of mass curving spacetime so I don't see how it rules out something like angels being responsible.
    I didn't say any observation ruled out your angels. I said that the ability of space-time curvature as an explanation to make predictions which have been verified makes this a superior explanation in which we can have confidence as being an accurate reflection of reality.
    And if we have strong confidence that space-time curvature is the cause of gravitational effects we are correspondingly sceptical about other competing explanations. Especially ones which are wholly unevidenced and unable to make any predictions at all.
    Surely this is simply inarguable?

    Re: Has The Supernatural Hypothesis Failed?
    The supernatural hypothesis has failed.
    By what standard are we judging its failure? It seems disingenuous to judge something on a scale it was never claimed to occupy.
    So given this epic failure of the supernatural hypothesis to date is it time to abandon this hypothesis?
    There is no such thing as a 'super natural hypothesis'. An hypothesis by definition must be testable. By placing our hypothesis out of the realm of the natural, it is impossible to, through the natural empirical means to which the scientific method is subservient, verify or falsify—that, to test.
    Anyone who believes supernatural notions scientifically testable is either misguided or a liar or quack. Others realize it is outside the realm of science, and thus any judgement on it by science as being a failure is clearly inappropriate.
    So, by what standard are you judging it as a failure? And, is it appropriate to apply this standard to the notion of the supernatural?

    There have been many tests of the supernatural hypothesis.
    One simple example: determining that thunder and lightning were not caused by Thor.
    Science tested that issue, and determined that there was a natural cause. Those who believed in a supernatural cause were shown that there was no evidence supporting their belief.
    Multiply this by hundreds or thousands of tests. (This would have been enough evidence for any field of science, but those who believe in the supernatural are not susceptible to such evidence.)

    Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.

    Re: Has The Supernatural Hypothesis Failed?
    So you think the existence of the supernatural has never been posited as the cause of any observable phenomenon?
    Sure it has. What does that have to do with what I said? It doesn't matter what it seeks to explain, it's simply not an hypothesis—and not subject to review by the scientific method—if it precludes from its very form any scientific means of falsification, which is what supernatural explanations do.
    Science is biased against supernatural explanations; it excludes them on account of their being non-natural. There is nothing wrong with this, but it does mean that we cannot use science to falsify or verify supernatural explanations, and as such we cannot judge the veracity of a supernatural claim via the scientific method. We need an alternate, more appropriate, ruler against which to test such claims.

    Re: Has The Supernatural Hypothesis Failed? Yup.
    One simple example: determining that thunder and lightning were not caused by Thor.
    Science tested that issue, and determined that there was a natural cause. Those who believed in a supernatural cause were shown that there was no evidence supporting their belief.
    Again, read what I've written. If the explanation is supernatural, then the natural methodologies of the scientific method do not apply. We found a natural explanation for lightening, but our tests and resulting explanations had nothing to do with old Thor.

    Do you think there is a supernatural causes for apples falling from trees?
    Do some things happen by themselves or is supernatural involvement required for everything?
