  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    The problem with objecting to the two-place predicate M()() in premise (1) without looking at premise (3) is...Leontiskos
    If you want to raise your own objection, go ahead. I've raised mine, with (1), and you have yet to address it.

    Why don't you think he is making use of ampliation in (1)?Leontiskos
    I explained that, with the comparison to infinity and transfinite numbers given then quoted above. TO achieve the desired ampliation one needs to go a step past g:=ix¬(∃y)M(y,x), just as one can't get to infinity by iteratively picking the next highest number.

    I'm sorry you are not following this, but that's the third time I've made the point.
  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    Your objection relies on the idea that some concepts cannot exist even as beings of reasonLeontiskos

    Yep. Concepts that contradict themselves. Like "The largest number". That's what I explained previously. If your argument is to hold, you have to show that "the greatest thingie" or whatever is not of this sort.
  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    Banno is engaged in a form of concept denial, which he would need to flesh out.Leontiskos

    So you want me to flesh out your concept of god for you.

    I don't think so.
  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    It sounds like you're saying that we can't have a being of reason if it isn't a being. Or in other words: we can't think of what doesn't exist. "X doesn't exist, therefore we cannot think of it."Leontiskos
    No.

    And so far I am only looking at premise (1), no further. We can go on when this bit has been understood.

    But the proof at hand does not assume thatLeontiskos
    Yeah, it does, and that can be shown. But you wanted small steps.

    you simply overlook Klima's "ampliation"Leontiskos
    Not at all. I address it quite specifically:
    Trouble is, that is not what g:=ix¬(∃y)M(y,x) says. God is still a thought object, albeit the greatest thought object.Banno
    One of the points I made is that Klima does not make use of the "ampliation" in (1), and he ought. The point was repeated and expanded, here:
    Following the analogue, the first transfinite number is

    ω:=min{x∣x is an ordinal and ∀n∈N,n<x}

    You need something like this, but with g for ω. But notice that ω is an ordinal, and is define as greater than any natural number. This avoids the contradiction that would result if ω were defined as greater than any other ordinal, or as a natural number greater than any natural number.

    So you can't just write g:=ix¬(∃y)M(y,x) without a problem, becasue it may be that there is no greatest individual. You need god to be something else, not an individual or not a part of the domain or something, to avoid shooting yourself in the foot.

    But if you manage that, you have the analogue of the transfinite numbers - no sooner have you defined g as the greatest, and then you can bring to mind something greater than g, and the problem repeats itself.

    So even as there is good reason to think that it is not possible to make sense of "the largest number", it is difficult to see how to make sense of "the greatest individual".

  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    Yeah, all that, perhaps, but I also gave a very specific critique of (1) in the argument.

    At least Tim tried to address it.

    And again you misrepresent what I said. I did not claim all ontological argument beg the question. IF the argument is valid, and it shows that something exists, then that must be assumed in the argument somewhere. That's how logic works. The problem isn’t just that the argument assumes its conclusion, since as Tim pointed out all valid deductive arguments do that. It's that it does so in a way that makes the supposed proof of existence trivial. The argument becomes "God exists therefore god exists".
  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    Gaunilo of Marmoutier took this approachCount Timothy von Icarus
    Close, perhaps. This objection is specific to the argument at hand. The intrinsic limit needed is missing from g:=ix¬(∃y)M(y,x), which is "God is defined as the thought object x such that no y can be thought to be greater than x", and the objection is not that anything might fit this, as that nothing might fit this. The question is, is the idea of such an object coherent? It's analogous to defining a number x such that no number y can be greater than it. There an be no such number.

    It doesn't help to say that there may be intrinsic limits to god's greatness, becasue of the way (1) is set out.

    if the issue is that the conclusion must be contained in the premises, that's a problem for all deductive arguments.Count Timothy von Icarus
    Quite so. It would be a surprise if an argument could demonstrate the existence of something ex nihilo, as it were. And yes, what is assumed is a being of thought. But what supposedly pops out of the algorithm is something else. The move from ens rationis to ens reale only works if we already accept that "existing in reality" is a necessary property of the greatest conceivable being.

    We can see this more clearly in free logic, taking the inner domain as ens reale and the outer domain as ens rationis. Stealing from the SEP article, the theist would need an argument of the form:

    ...where Ti might be the assumption that god is the greatest possible thought object, and E!i that god exists in reality. But such arguments are invalid.

  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    Well, I'd like to talk about the argument rather then the formatting. Can we move on?

    Maybe you could reply to what I said about (1).
  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    Your misrepresentation is still there: (1) g=dfix.~($y)(M(y)(x)) (as well as the other lines of the proof where similar problems occur).Leontiskos

    You seem to be talking past me.

    a single question, yes or no: is
    g:=ix¬(∃y)M(y,x)
    a good representation of line 1? Or do we need to use mathjax?
  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    Klima is explicit that step (2) is a supposition and that step (1) is a definition, so I'm not sure what you're attempting to disagree with.Leontiskos

    To be sure, it is not clear that the definition g:=ix¬(∃y)M(y,x) can be made coherently, any more than can "Let G be the number bigger than any other number".
  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    Okay, so you're not actually objecting to step (2) of the proof?Leontiskos

    Well, not yet. One at a time.

    I did fix the ugly: g:=ix¬(∃y)M(y,x). I asked you if it was acceptable, and did not yet get a reply.

    I'm gonna Pontifications from 30,000 feet again. The generic flaw in ontological arguments is that if they are valid then they assume the conclusion somewhere in the argument. The task for the logician is to find out where.

    They must do this because existence cannot result from a deduction. It can only be presumed, either in the argument or in the interpretation.

    For the theist, the assumption is often trivial, even self-evident. But not for others.

    So the argument will not be of much use in convincing non-theists. As here. But on the other hand, it also does not disprove that god exists, and it may be of use in showing god's nature to theists.

    From were I sit it looks to be another example of trying to put the ineffable into words, and getting tongue-tied.
  • What does Quine mean by Inscrutability of Reference
    Yet no one would understand each other if they were always making different sounds to refer to different things in each instance, so we "cannot" have a human language that works like that.Count Timothy von Icarus

    Bang on!

    And yet we do understand one another, at least enough to have invented social media.

    So what is your answer? How is it that "dog" refers only to the canine, and not the police officer? In virtue of what does this occur? What fixes the referent?

    The answer given previously was the Humpty Dumpty account, but that cannot explain mutual agreement any more than does "dog dog dog dog dog dog dog."
  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    Might be.

    The analogue you want is the jump from there being no highest number to a number greater than any assignable quantity - to infinity, and beyond! You want to jump from something greater than anything to something greater than greatness...

    And the suggestion is that there need be no such thing. But also, that g:=ix¬(∃y)M(y,x) does not give an definition in line with this second account.
  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    Good. This is what I mean by "engaging the paper."Leontiskos

    Though shalt engage only in ways expected by Leon.

    In fact, much of your quote is a misrepresentation of what Klima writes in the paper. You were presumably copy/pasting without checking to see if the output was accurate. A bit more care would be welcome, given how much people struggle with formal logic even before you start incorporating symbols like $, ", ®.Leontiskos
    What? Those are the symbols in the HTML text you linked.

    Ok, so are you claiming g:=ix¬(∃y)M(y,x) is not an accurate presentation of (1)? Then what is?

    You are saying the number does not exist, but you also require that the thought object of the number does not exist.Leontiskos
    No. Kids will ask wha the highest number is. Takes them a while to see that there isn't one. Theists similarly ask what the greatest being is. Since they already think they know the answer, the question is disingenuous.
  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    That's probably what this is trying to head off:

    As he says: “what if someone were to say that there is something greater than everything there is [...] and [that] something greater than it, although does not exist, can still be thought of?” Evidently, we can think of something greater than the thing greater than everything, unless the thing that is greater than everything is the same as that than which nothing greater can be thought of. But Anselm’s point here is precisely that although, of course, there is nothing greater than the thing greater than everything, which is supposed to exist, something greater than what is greater than everything still can be thought of, if the thing greater than everything is not the same as that than which nothing greater can be thought of. So if the thing greater than everything is not the same as that than which nothing greater can be thought of, then something greater still can be thought of; therefore, that than which nothing greater can be thought of can be thought of, even if it is not supposed to exist.

    What a mess. So god is not the thing greater than everything, but the thing greater than the thing greater than everything.

    Trouble is, that is not what g:=ix¬(∃y)M(y,x) says. God is still a thought object, albeit the greatest thought object.
  • What does Quine mean by Inscrutability of Reference
    However, if reference wasn't fixed by convention at all there would be no need for languages in the first place. The sound of "dog" could be arbitrarily assigned to some referent in each instance.Count Timothy von Icarus

    I must be missing something, since it seems clear enough that the sound of "dog" could be arbitrarily assigned to some different referent in each instance.

    We work out that it is - or isn't - as the conversation progresses. Sense making is a process, not a given, not fixed by divine providence or some such nonsense.
  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    (1) g=dfix.~($y)(M(y)(x))

    Seems to be, in a more standard notation, g:=ix¬(∃y)M(y,x). God is defined as the thought object x such that no y may be thought greater than x.

    ix is the definite description operator, read as "The x such that...".

    Notice that the existence (as a thought) of such an individual is here just assumed.

    Why should we make that assumption? In particular, if the definition is self-contradicting, there need be no such individual.

    Consider an analogous argument defining the highest number as that number which is higher than any other number. The definition is fine, except that there is no such highest number.

    A pretty standard response to that part of the Ontological argument.

    Banno read the whole paper, which you say you have not yet done, then followed the guidelines you set up in posting about the first section. I was following your instructions.

    Having done so, it is disingenuous for you and Tim to then censure me for it. But that's the trouble with presenting an article for critique when what you desire is agreement.

    But I am happy for you, Leon, to make this thread about me, if that is what you want.


    The alternative to descriptivist theory, from the paragraphs following the one I cited above, is some variation on an intentional theory of reference - "linguistic expressions refer to what their users intend by them to refer to in a given context". Perhaps not quite he Humpty Dumpty theory of meaning, "When I use a word, it means just what I choose it to mean - neither more nor less", since there is an implicit recognition of a community of "users". And an acknowledgement of modality in that one can refer to things that do not "exist", where what it is to "exist" remains obscure.

    In modal terms, there are things in the actual world and things in possible worlds, and we can refer to either. But it might well be closer to the text to use a free logic, in which a singular term - a proper name - maybe used not just for things in the domain, but also for things outside it, hence permitting discussion of "supposita".

    In a free logic there are two domains, one, inner domain for things that are really real, and another outer domain for things that are not so real, but we still want to talk about. So the question Anselm raises is, we have the description "a something a greater than which cannot be conceived"; is it in the outer domain, or is it in the inner domain? And much of this part of the article is concerned with showing that this is not the same as asking if there is a greatest something. Seems fine.

    We should here make a distinction between two different uses of quantification - of "all" and "some". There is the other use of quantification to say that something is an individual in the domain: "There is exactly one thing that is the author of Tom Sawyer". This is the quantification used by Quine in his "to be is to be the value of a bound variable". Then there is the extension of this applied to the descriptive theories of reference, where "There is exactly one thing that is the author of Tom Sawyer, and it is the very same as Mark Twain" supposedly explains how "Mark Twain" manages to refer to Mark Twain. The former is distinct from the latter, and the former provides one way to talk about what it is to exist, the latter is a somewhat discredited philosophical theory.

    Yawn.
  • Disagreeing with Davidson about Conceptual Schemes
    Your criticism worries me more than McDowell's.

  • Disagreeing with Davidson about Conceptual Schemes
    Thanks for the response. Perhaps we re talking past each other? So I'll try again.

    This experience, on McDowell's view, provides her with a reason to believe that the cat is on the mat because in having this experience, the fact of the cat being on the mat is made manifest to her.Pierre-Normand

    Now this is at odds with Davidson, but also I think it is not accurate. The "experience" here is already the belief that the cat is on the mat, already interpreted. So if it were to "give you a reason" to think the cat is on the mat, that would amount to "the cat is on the mat becasue the cat is on the mat".

    It's not too far from Moore's "Here is a hand"...

    Seeing that the cat is on the mat is not a reason to think the cat is on the mat so much as believing that the cat is on the mat...

    So we have two differing accounts, and I think Davidson's the better.
  • St. Anselm's Proof: A Problem of Reference, Intentional Identity and Mutual Understanding (G. Klima)
    The first sentence of section one says:

    On the paradigmatic account of reference in contemporary philosophical semantics, owing in large part to Russell’s Theory of Descriptions, the burden of reference is taken to be carried basically by the bound variables of quantification theory, which supposedly reflects all there is to the universal logical features, or “deep structure” of natural languages.

    The descriptive theory of reference had its heyday in the time prior to Kripke. So this struck me as at best inaccurate. But to check I went to the PhilPapers survey and found support for causal views on reference at 46% and for descriptions at 17%. Hardly "paradigmatic".

    So it seems to me this paper missed it's target by fifty years or so. Mediaeval critique of historical aspects of logic is a pretty fringe market.



    Edit: Copied here from later in the thread, so I don't lose it.

    Summarising my comments on section 2, here are four problems with the argument as it is present.

    1. There is a problem in defining a maximum element in a domain that may have no limits.
    2. There is a sleight of hand from ens rationis to ens reale, somewhat hidden here but brought out in Free Logic by the invalidity of a move from Ti to E!i.
    3. There are four premises to the reductio, any or each of which may be false. That the second assumption is the one that must be rejected is not established.
    4. The argument relies on a substitution within an intensional context, at line (5), that is not justified.

    And finally, (1) and (3) in combination make the assumption that god exists. This explains why the argument is valid, since it amounts to "god exists, therefore god exists". It also makes the argument circular.


    Edit: I placed my summation fo the article here.
  • Disagreeing with Davidson about Conceptual Schemes
    It might help if you would sketch the argument that you take McDowell to be misapprehendingPierre-Normand

    Why? I'm not making McDowell's argument. If you think he has a case, then you can make it.

    Thanks for the response.

    We ought be careful not to think of seeing the cat on the mat as happening in isolation, especially since this is what Davidson says does not happen. That what we see is interpreted as cat and mat is not seperate to the belief - in a sense it is the belief, caused by the physics and physiology of the situation. The physics and physiology cause the belief that the cat is on the mat; the "experience" doesn't "contribute to the justification" that you see the cat, since there is no justification. You see the cat. The experience is not isolated from the beliefs.

    So thinking of LE as a belief about your experience would not fit Davidson's account. Part of what is going on here is an ambiguity in introducing the term "experience". A better way to say this would be that the physics and physiology cause the belief; dropping the word "experience".
  • What does Quine mean by Inscrutability of Reference
    Are you now suggesting that there is a convention that if you and I are sitting in an empty room with a dog, and I say, "The dog," there is a fixed referent?

    Yep.
  • Disagreeing with Davidson about Conceptual Schemes
    I think spiders do experience things, and I think it's probably so different from my own experience that if we could upload the spider's thoughts and download them into my brain, my mind would just detect inexplicable noise.frank

    I wanted to come back to this, to make a point this time about what conceptual schema are not. They are not a neural network.

    Frank's description here is part of the reason I thought his OP excellent, since it makes explicit a misunderstanding of the relation between brain and mind. Frank may well be quite right that if the spider neural net were somehow grafted to his own, the result would be noise. But that need not count against Davidson's account. The beliefs of the spider sit apart from the mere firing of the neural networks that cause it's movement, and cannot be reduced to them. Indeed, it is problematic to attribute beliefs to the spider at all, since beliefs sit within the broader framework of of triangulation, interpretation, and hence occur at a level that it utterly foreign to the spider.

    Which is just to say, we can explain the behaviour of the spider in terms of belief, but the spider cannot.

    For Davidson, mental events—like beliefs, desires, intentions—are not reducible to physical events. There is no deterministic, law-like relationship between the two; instead, mental descriptions are interpreted within the broader context of social practices and linguistic frameworks.

    Hence the anomalism of the mental. There need be no correspondence between physical stats and the intentional descriptions of them.
  • Disagreeing with Davidson about Conceptual Schemes
    The supposed illusory nature of certain experiences is trivial. Consider that we are aware that they are illusions. We are aware of this becasue they are evaluated by the whole web of belief, and not segregated and separated as "experiences". The "Need" McDowel sees to "distinguish the experience" suggests a profound misapprehension of Davidson's much more subtle argument.

    That is, I don't see much value in McDowell's comments. While you are welcome to try to convince us otherwise, so far, I'm not seeing it.
  • Disagreeing with Davidson about Conceptual Schemes
    For Davidson, the "world-in-itself" is a nonsense. His is a rejection of "Cartesian" and "representative" approaches. Indeed, it follows Wittgenstein in rejecting that sort of dualism, the very grounding of the realism/idealism dichotomy. It's not that there is one conceptual scheme, but that the very idea cannot be made coherent.
  • Disagreeing with Davidson about Conceptual Schemes
    We were talking specifically about empirical judgements and their justification.Pierre-Normand
    You might be. I think the discussion should be somewhat broader.

    Davidson's claim that experiences cause agents to acquire beliefs is an expression of his conception of empirical experience, not belief.Pierre-Normand
    Of course it is an expression of his conception of belief. How could it be one and not the other? That would be to reintroduce the scheme - content dualism he rejects. He denies that there is a place for experience in our knowledge apart from our beliefs. There can be no "pure experience" separate from our ratiocinations; any empirical judgements already have the whole web of belief "built in". If McDowell seeks to seperate out again the experience from the judgement, he is a long way from Davidson.

    And I think mistaken.

    But this is a thread about Davidson, not McDowell. That McDowell misapplies Davidson is neither here nor there.
  • Disagreeing with Davidson about Conceptual Schemes
    Davidson denies, as the third dogma of empiricism, that a distinction can be maintained between a conceptual component and an empirical component; between supposed objective and a subjective aspects of knowledge.
  • Disagreeing with Davidson about Conceptual Schemes
    The idea that Davidson would deny that some of our beliefs might be the product of ratiocination is absurd.

    If nothing else it ignores triangulation and holism, and that interpretation itself is a rational process.
