  • Scripture as an ultimate moral dilemma
    On the other hand, what if something important has happened that should be passed on? Is that a possibility or not? I don't see how a strange argument bogged down in cynicism is going to undermine such a possibility.
  • A challenge to Frege on assertion
    When he mentions the first chapter, Soames is talking about an examination of the relationship between utterances, sentences, and propositions, with the goal of explaining why the concept of a proposition is indispensable.frank

    Your quote nowhere says that for Frege a proposition is a thought. Do you realize that?

    Did you have some source that conflicts with that?frank

    Have you read the OP?

    Frege says, “A proposition may be thought, and again it may be true; let us never confuse the two things.” (Foundations of Arithmetic)J

    Here is IEP:

    For this and other reasons, Frege concluded that the reference of an entire proposition is its truth-value, either the True or the False. The sense of a complete proposition is what it is we understand when we understand a proposition, which Frege calls “a thought” (Gedanke). Just as the sense of a name of an object determines how that object is presented, the sense of a proposition determines a method of determination for a truth-value.Frege | IEP

    Those who find that language distasteful probably shouldn't be discussing Frege at all.frank

    Those who don't know what they are talking about probably shouldn't be giving lectures.
  • A challenge to Frege on assertion
    If you find a logical system that says "The sky is blue" and the "snow is white" and all you are doing is writing expressions like, "This is a fact." "this is a true assertion".. what the duckn difference does it make if you cannot show why it's true, or how it's true?schopenhauer1

    Why shouldn't it make a difference? Is justification the only thing that matters? The only thing we can talk about? If you want a thread on justification then you should start it. This thread is not about justification.

    When Frege talked about propositions, he was talking about thoughts.frank

    I will simply note that, yet again in misrepresenting Frege, you provide no source for your claims. Cf.

    - was right on the money when he said that your desire to keep using that word "proposition" gets us nowhere, as it is used very differently by different authors.

    Can you give an example of that?

    Here is Russell:

    In language, we indicate when a proposition is merely considered by “if so-and-so” or “that so-and-so” or merely by inverted comma’s. (PM, p. 92)Frege, Russell and Wittgenstein on the Judgment Stroke, by Floor Rombout, 45

    -

    Ordinarily we must take something away from a statement in order to sequester the assertoric force, because the assertoric force is a natural part of a declarative sentence. In Russell and Wittgenstein's misunderstanding Frege's judgment-stroke is something added on to a proposition or "assumption," and hence becomes a symbol in its own right.

    For Frege it is more complicated. For Frege it is a stroke, not a symbol. It is "syncategorematic" (Kimhi) and hence is in no way on the same plane as the symbols of the sentence. The difference between a mere horizontal and the horizontal with the judgment-stroke added is a distinction in mente, and exists for the purposes of logic and inference. The judgment-stroke is sui generis, and this reflects Kimhi's emphasis on the fact that thinking is unique. It is a bit of performative language rather than descriptive language.

    If there is some problem (qua Kimhi) with Frege's judgment-stroke it is an incredibly minor and subtle problem. Wittgenstein's complaint is more intelligible, but it is a one-way ticket to a destination that Kimhi will have no part of (which is apparently why he snips Wittgenstein's critique out of its context each time he references it in his book).
  • A challenge to Frege on assertion
    - I am content with the response I already gave to that tangential topic.
  • A challenge to Frege on assertion
    I just reread my OP, which included my optimistic belief that we didn’t have to be concerned with “what Kimhi says” in order to understand the question I was raising. Ha!J

    I think that in order for the critique to make sense it must be linked up to some goal of Kimhi's. Kimhi must be made to say, "This point in the OP matters because it can be linked up to my larger concern of X."

    But I thought, and still think, that a much deeper question is being raised here, a metalogical one about how what we think and can say is related to our existence claims about what is.J

    Does Kimhi ever directly attack Frege on that front? On the existence-predicate?

    This is the tangent that most interests me in this thread: How is it that logic becomes separated from thinking, judgment, and consciousness?* Ironically Rombout seems to trace this to Wittgenstein, in which case, pace Kimhi, (early) Wittgenstein does not save us from Frege, he takes Frege to the place that Kimhi finds most problematic.Leontiskos

    The difficulty I have with Kimhi is that we are considering the foundation of his project, and that foundation seems to be based on two misreadings: first, Wittgenstein's misreading of Frege that Kimhi follows unquestioningly, and second, a misreading of early Wittgenstein. If Frege is bad then early Wittgenstein is much worse, and it is muddled for Kimhi to think that early Wittgenstein is his ally against Frege. Kimhi thinks Frege is too thin, whereas early Wittgenstein was saying that he is too fat. I see concentric circles of the "any stick to beat the devil" fallacy, where one affirms a thinker whose conclusion they desire, even if the arguments to get there do not hold up.

    Kimhi is right that Wittgenstein disagrees with Frege's judgment-stroke, but he seems to have overlooked the fact that it is for a completely opposite reason than his own. And Kimhi is right that there are problems with first-order logic, but I don't know that Kimhi's critique itself holds water, at least on this assertoric front. In longer-lasting systems of thought such as Catholicism one comes to be very careful about genealogical arguments, and the OP seems to represent a poor genealogical argument. Kimhi sees a problem with first-order logic, and he wants to trace it to its root. But there is no obvious root, and in tracing it to Frege's judgment-stroke Kimhi seems to have alighted on a false genealogy.

    I think Rombout gives a much sturdier genealogy: the cleavage of epistemology from logic comes from Russell and Wittgenstein's misappropriations of Frege. Is some of it Frege's fault? Probably, but Wittgenstein is the central actor here. Wittgenstein's "solution" to the foundational Meno dilemma is to have a radical divorce between epistemology and logic. This is simply a non-starter if logic is supposed to provide an account of how progression in knowledge occurs. As Rombout says, Frege and Wittgenstein have an entirely different understanding of what 'logic' even means.

    ...and the more Frege I read, the stronger he stands against Kimhi. To take one example, Narboux's Notre Dame review ends by pointing out a problem in Kimhi's Wittgenstenian-colored idea of propositions being understood in large part in light of negation. This is a mistake that Frege, Thomas, Augustine, Parmenides, and probably also Aristotle all avoided. Frege's understanding of 'p' in that metalogical sense seems to in fact be better thought out and more robust than Kimhi's (although if Frege did not understand the difference between denial and negation then part of this was a happy accident for him).
  • Advice on discussing philosophy with others?
    Welcome!

    My advice would be simple: be transparent and honest. Don't pretend to know what you don't know, and don't be afraid of saying something that may turn out to be wrong. That way people will know what you are thinking and they will be able to engage with it. A thread I wrote is related: Argument as Transparency.
  • A challenge to Frege on assertion
    Belief in a story would be a different flavour of belief than the one in this thread anyway. Telling a story is, at least, a sequence of sentences presented with different forces and roles, and we've been dealing with single sentences with possibly a single illocutionary force.fdrake

    This is part of what I was trying to get at when I said that fiction is much less univocal than logic. :up:

    The boring deflationary answer is just to say that understanding a given text as a story means just the following: belief in any presented sentence in that text is equivalent to believing that that sentence is a part of the text. Line of the story as story event. I believe that Gollum lied and cheated if and only if it says so in the book.

    Suspension of disbelief works in opposition to the latter boring answer. Like the deus ex machina eagles at the end of Lord of the Rings. A flight of massive eagles coming in and saving the day, really? You only doubt it, "c'mon, really?" because you believe it happened in the story, but it could be felt to collide with the story's narrative. No one would doubt the eagles came, they just would doubt whether in some sense they should've.
    fdrake

    Yes, good, and we can take this in a Platonist direction contrary to your second deflationary theory. The question of whether logic or fiction is more 'real' can be assessed according to the question of whether logical analysis or narrative is more foundational to human life. If narrative is the meta-category of human life, then any genre of story (including fiction) will be more real than logic. On the other hand, if scientia is the telos of human life, then logic has a primacy over fictional narrative. I think there is a very strong case to be made in favor of the view that narrative, not logic, has the primacy.
  • A challenge to Frege on assertion
    My point is that first and foremost the fiction writer *pretends* to have such warrant. In early prose fiction this is almost universal (in English anyway).Srap Tasmaner

    Granted, and I pointed to the same thing early on in the discussion:

    Yes, and it is interesting that in recent history fiction was thought to require a kind of disbelief-suspension-bridge (I forget the real name that is used). Some plausible device was used to connect the fiction to the real world.Leontiskos

    -

    Nowadays, we're used to how fiction works and it's dramatically less common to go through this little dance.Srap Tasmaner

    Sure, but it's worth recognizing that it was never anything more than a dance.

    It's not novel to say that something is stripped away when we engage in logical analysis. It's more or less the point. The question is whether what you have left, that you'll submit to logical analysis, is what you think it is, and whether the pieces fit when you try to reassemble the living use of language.Srap Tasmaner

    Yes, that's a very good way to put it. :up:

    So if we take our shears to an asserted sentence we can apparently remove the basic assertoric force. Then if we take our shears a second time we could apparently remove the grammatical aspect and achieve the result of "mere words." Then a third time, and be left with mere tokens or letters. One way to phrase the question is this: Is the "sharpness" of Frege's shears intelligible or arbitrary?

    -

    It's in the TLP (according to my lazy history of logic) that we get the presentation of tautology as a true statement that says nothing. And if it says nothing, evidently not a picture. So the truths of logic are something else entirely, and it is only there, among these whatever-they-ares, that we get self-evident truth.Srap Tasmaner

    This is the tangent that most interests me in this thread: How is it that logic becomes separated from thinking, judgment, and consciousness?* Ironically Rombout seems to trace this to Wittgenstein, in which case, pace Kimhi, (early) Wittgenstein does not save us from Frege, he takes Frege to the place that Kimhi finds most problematic.

    * But not construed as Banno's full-on logical nominalism, where logic is merely symbol manipulation. That is called metalogic or metamathematics and is not generally seen as logic itself. The result was not logical nominalism, but instead a sort of reification of truth as something that exists independently of subjects and minds. A kind of overcorrection of "psychologism."
  • A challenge to Frege on assertion
    Yes, which is why I keep trying to find some better, more perspicuous ways to carve up "force." I was leaning toward believing that "force" itself should be strictly separated from both assertion and illocution -- or that, at least, Kimhi would want us to think of it that way. I'm no longer sure, based on the many interesting comments from yourself, leontiskos, @srap tasmaner, @frank and others.J

    In those terms the question is simply whether Kimhi sees something which "displays (assertoric) force [without being a self-identifying display]" as having some kind of force. Regardless of words, Kimhi's point seems to be that Frege's Point excludes the possibility that a sentence displays assertoric force. I don't see Kimhi in any way moving away from assertoric force to some kind of general force.

    This is more or less where I was going with my hard-to-follow speculations about the universal quantifier. Russell's TDD postulates existential quantification for proper names, if I'm remembering rightly. And you had said that "so far as existence is defined, it is defined in terms of the universal quantifier." So my question was, If Frege does not accept the TDD, can we spell out how universal quantification might still give us something to think about when we think about names?J

    In the parts of Frege that I have read he shows no interest in the epistemic aspect of a proper name, which is probably a credit to him. He takes it for granted that a proper name can designate an object.

    A lot of what Kimhi (and Rodl) are doing is probing presuppositions of formal logic. There is a lot of magic involved in formal logic, and I suppose the question asks how much presuppositional magic is to be granted. Kimhi's broader thesis is that by adopting a Fregian approach first-order logic has merely side-stepped some of the biggest problems of philosophy, which persist as elephants in the room rather than vanquished foes.

    -

    Can't you have a mistaken or in-part inaccurate understanding of what truth is, and discover in the course of my lecture what the "truth about truth" is?J

    Frege understands that prefixing "It is true that..." to a sentence both adds something and doesn't add something. It is slippery. But the odd parallel is that his judgment-stroke also adds something and doesn't add something, in just the same way.
  • A challenge to Frege on assertion
    Folk seem too keen on claiming that one cannot understand what a statement is about without deciding if it is true or false.Banno

    I don't think anyone has claimed this. The point that Wittgenstein makes has to do with conditions for truth or falsity, not a decision.

    I don't think anyone has made that claim. You probably need to understand the truth conditions, but not whether it's true or false.frank

    Yes, exactly. :up:
  • A challenge to Frege on assertion
    Frege makes a very interesting comment in the context of dissociating assertoric force from the predicate, and it relates to Kimhi:

    . . .Assertoric force is to be dissociated from negation too. To each thought there corresponds an opposite, so that rejecting one of them is accepting the other. One can say that to make a judgement is to make a choice between opposites. Rejecting the one and accepting the other is one and the same act. Therefore there is no need of a special name, or special sign, for rejecting a thought. We may speak of the negation of a thought before we have made any distinction of parts within it. To argue whether negation belongs to the whole thought or to the predicative part is every bit as unfruitful as to argue whether a coat clothes a man who is already clothed or whether it belongs together with the rest of his clothing. Since a coat covers a man who is already clothed, it automatically becomes part and parcel with the rest of his apparel. We may metaphorically speaking, regard the predicative component of a thought as a covering for the subject-component. If further coverings are added, these automatically become one with those already there. — Frege, Introduction to Logic – Posthumous Writings, 185

    Soon after this, Frege expresses frustration that 28 years after he introduced the material conditional mathematician and logicians continue to resist it as something bizarre! Curiously, in speaking of his “conditional stroke,” he claims that the relation designated by the conditional stroke is not strictly speaking something that obtains between thoughts, but rather that the sign for the conditional stroke connects sentences. This seems to indicate that he posits a non-assertoric difference between the two p’s in the premises of a modus ponens.
  • A challenge to Frege on assertion
    - Sure, but given that Frege understands language differently than the subject-predicate model of ordinary language which he intentionally diverges from, what more is there to say?

    Here is Frege on this issue:

    Therefore when Kerry says that my criterion does not meet the case, claiming that in the sentence ‘The concept that I am now talking about is an individual concept’ the name composed of the first eight words surely means a concept, the contradiction does not lie in what I have laid down; it obtains between the sense I attach to the word ‘concept’ and that adopted by Kerry. But nobody can require that my stipulations shall be in accord with Kerry’s mode of expression, but only that they be consistent in themselves. True, we cannot fail to recognize that we are here confronted by an awkwardness of language, which I admit is unavoidable, if we assert ‘the concept horse is not a concept’, whereas, e.g. the city of Berlin is a city, and the volcano Vesuvius is a volcano. Language is here in a predicament that justifies the departure from what we normally say. The peculiarity of our case is indicated by Kerry himself by means of the quotation-marks around ‘horse’. (We have used italics here to the same end.) There was no reason to mark out the words ‘Berlin’ and ‘Vesuvius’ in a similar way above. In logical discussions one quite often needs to assert something about a concept, and to express this in the grammatical form usual for such statements, so that what is asserted becomes the content of the grammatical predicate. Consequently, one would expect the concept to be the content of the grammatical subject; but the concept as such cannot play this part, in view of its predicative nature; it must first be converted into an object, or, speaking more precisely: an object that is connected with it in accordance with a rule must be substituted for it, and it is this object we designate by an expression of the form ‘the concept x’. (Cf. p. X of my Grundlagen.)

    So the phrase ‘the concept horse’ must be regarded as a proper name, which can no more be used predicatively than can, say, ‘Berlin’ or ‘Vesuvius’. If we say that Bucephalus falls under the concept horse, then the predicate here is clearly ‘falling under the concept horse’, and this has the same meaning as ‘a horse’. But the phrase ‘the concept horse’ is only part of this predicate.

    When I wrote my Grundlagen, I had not yet made the distinction between sense and meaning; and so, under the expression ‘content of possible judgement’, I was combining what I now distinguish by the words ‘thought’ and ‘truth-value’. For this reason I no longer hold my choice of expressions in the second footnote to p. 77 to be quite suitable, although in the main my view remains the same: a concept is essentially predicative in nature, whilst the very opposite is true of an object, so that a proper name (sign or name of an object) can never contain the whole predicate.
    — Frege, On Concept and Object – Posthumous Writings, 97 – footnotes omitted

    1. The concept horse is not a concept
    2. [The concept horse] is not a concept
    3. The city of Berlin is a city
    4. [The city of Berlin] is a city

    Frege interprets the parts in brackets as, “A proper name in the logical sense,” which, “is a sign for an object.” Ergo: if the last three words of (3) and (4) were absent we would not know that 'Berlin' is a city (because proper names are not predicative). Frege grants that (3) is unintuitive given its redundancy, but he is unperturbed.
  • A challenge to Frege on assertion
    - @J seems to want us to say that Frege would have it that 'Berlin' has meaning and significance even apart from any predicate or quantification, as it does in everyday language.
  • A challenge to Frege on assertion
    It's fairly clear that assertion is integral to a proposition. The question is: what does it mean to separate them? By what means does Frege do that? If it's by way of a stipulated logical domain, yes you can separate them. In real life? No, you can't.frank

    I think these are the right considerations, although I think you can remove the assertion in "real life" too.

    Kimhi's argument is something like this:

    1. In order to assert a (declarative) sentence, I must first judge whether it is true or false
    2. In order to judge whether it is true or false, it must have a judgable content
    3. In order to have a judgable content, it must display assertoric force
    4. In order to display assertoric force, it must contravene "Frege's Point"
    [5. Therefore, "Frege's Point" prevents one from judging and asserting declarative sentences and engaging in the activity of logic]
    Leontiskos

    We could look at this from a different angle: What would it mean for someone to hold to "Frege's Point" to the extent that (4) is true? According to Kimhi, it would mean that they cannot do logic, for logic requires the ability to judge and assert declarative sentences (cf. 5).

    Is it plausible to attribute such a doctrine to Frege? Does he really want to divorce assertoric force from sentence to such an extent that the sentence cannot be judged true or false? If not, does he have the resources to stop short of that pitfall? Kimhi seems to say, "no."

    (I agree with Kimhi that Frege's analysis of assertoric force is not "natural," but beyond that I'm not convinced that it is as detrimental as Kimhi claims.)
  • A challenge to Frege on assertion
    Again, it is important to note that the very same sentence may have more than one logical treatment. ↪Leontiskos seems to miss this.Banno

    One can speak about modus ponens in terms of logical consequence or logical inference. Both make sense in their own context, but Frege actually adopts the latter approach. For Frege a modus ponens requires three judgment-strokes.Leontiskos
  • A challenge to Frege on assertion


    It can only occur once for an expression, but the question is whether a modus ponens is a single expression.Leontiskos
  • A challenge to Frege on assertion
    Pretending, as your examples demonstrate, is complicated, but I think it's actually very important to logic because of hypothetical reasoning (not to mention counterfactuals). I think it's very difficult to give an account of what happens when we entertain an hypothesis, but it looks a bit like pretending.Srap Tasmaner

    That's true, but I don't think that sort of hypothesizing is susceptible to formal logical analysis, as it is presupposed that the subject is doing this and I don't think formal logic can circle round itself to account for such a presupposition.

    So yes, somewhere back in the chain of how I come to be telling this story, to be in a position to tell this story, there must be witness or even participation. I was there and I saw it, or I had it from a guy who was there. The storyteller pretends to be such a person.

    This is, perhaps, a more colorful version of the Parmenides stuff.

    One consequence of such a view might be that it's not really the tale we believe but the teller. We do not adopt a propositional attitude of "belief" toward the story, except perhaps as a consequence of adopting a social attitude of "trust" toward the storyteller.
    Srap Tasmaner

    The historical development of how a fictional story is told is interesting, but are verification and warrant really at the center of fiction, at least in our own day and age? Or related at all? Isn't it a category error to challenge the fiction author regarding warrant?

    I suppose if we want to make fiction very logical we can think of it as an experiment in counterfactuals, and of course fiction with a strongly didactic motive is intended in that way. I mostly think that because fiction is a less univocal category than logic, logic won't make sense of it. Logic can work on something which has a clear and stable intentional character, but the raison d'être of fiction (or logic) is not available to logic in this way. Like "Berlin," fiction need not be or mean one thing. I don't think all fiction authors are involved in the same sort of intentional stance towards their work.

    (Out until tomorrow - take your time!)
  • A challenge to Frege on assertion
    Kimhi's argument is something like this:

    1. In order to assert a (declarative) sentence, I must first judge whether it is true or false
    2. In order to judge whether it is true or false, it must have a judgable content
    3. In order to have a judgable content, it must display assertoric force
    4. In order to display assertoric force, it must contravene "Frege's Point"

    The only question for me is whether (4) holds, or in what limited sense it holds.
  • Why should we worry about misinformation?
    It appears there are two-brands of "democracy" in conflict, the one that favors the power of the people, the other that favors the institutions that have arisen in representative democracies, for instance elections and parliaments and the credibility of those in power. It's an interesting conflict.NOS4A2

    Interesting, to be sure. :up:
  • A challenge to Frege on assertion
    the pretense is that you are removing something and pretending you haven'tSrap Tasmaner

    I think Frege would say that the fiction author has removed something from their words, whereas the fiction author would say that Frege has removed something from their words. Fiction may be inherently Platonic in that way. It may insist that it is giving more, not less, than what non-fiction gives.

    A better form for my question would be, what have you removed? What's missing, that everyone kinda pretends isn't, when you tell a (fictional) story? Does it overlap with what's left out when you only have a record of the words spoken, the bare, lifeless sentences?Srap Tasmaner

    But on the premise that fiction is less, I would suspect that an intention tertium quid is involved in fiction (though I am not sure whether it is a kind of quasi-assertion or else something with a different intentional force altogether). Does the fiction author make use of the assertoric force that the logician removes, as an ingredient in what he adds to the lifeless sentence in order to give it life? I don't know. What are your thoughts?

    As an aside, my friend's child always engaged in "pretend" without any notice, as if she paid no mind to the boundaries of pretending and not pretending. My nephew, on the other hand, is very precise about where pretending begins and ends, even at a younger age than the girl. Part of the difficulty of all this is that pretending and playing is very different from the logical thinking that Frege and Russell prefer, perhaps to the point of incommensurability. Perhaps if we "knew" what we were doing when we pretend or play we would cease to pretend or play. I'm not sure if you can reduce logic or pretending to the other, and this may be because logic specifies and marshals intentionality in a way that play refuses to do.

    (To ask her whether she was now pretending or not was much like asking someone to explain the punch line of a joke. Asking for illumination causes the sun to set.)
  • A challenge to Frege on assertion
    And one last point -- sorry for the multiple posts -- the whole point of my view of fiction is that it is parasitic on candid account giving or reporting. If we did not already have such a practice of reporting on real events that happened to real people in real places, and so on, we could not pretend to report on events we've made up (and maybe people and places as well).Srap Tasmaner

    Yes - that is the Aristotelian realism route and I am comfortable with it. It says that fiction is ultimately a rearranging of sense experiences and memory. But a Platonic account will say that the reality that we experience in sense is a reflection of the Forms, and that we can perhaps experience the Forms directly. This is the view that fiction could be a "higher reality" via its direct participation in the Forms.

    Then to bring this back down a bit, the point is that Tolkien obviously thinks he is doing something Platonic whereas H. G. Wells obviously thinks he is doing something Aristotelian. What this means is that Wells is pretending in a way that Tolkien is not, and therefore it becomes hard to give a single account of fictional intention to all fiction writers.
  • A challenge to Frege on assertion
    Yeah that was the idea. Is assertion something added on to the words?Srap Tasmaner

    Right...

    If you can add on assertion, are there other things you could add on?Srap Tasmaner

    Another way to look at it: if you're not sure whether assertion is something we add on (rather than being built in), does showing that we can add something instead of assertion show that assertion is something we add?Srap Tasmaner

    Maybe Kimhi would agree when I claim that it is strange to talk about non-intentional sentences. Supposing that assertion is one form of intentional 'force' (or simply intention), are there sentences without intention? And are there declarative sentences without assertion?

    If "Berlin" makes no sense apart from context, does a sentence make sense apart from intention? If not, then it would seem that in "adding" assertion to a putatively non-intentional sentence, we are in fact either altering the intention that was already present, or else a dead structure of letters and words becomes a living form when intention is infused (an essential change occurs). It may be that in analyzing the materiality of a sentence and prescinding from intention we are doing something like examining a corpse, or at least a comatose patient.
  • A challenge to Frege on assertion
    My view is that in a work of fiction the author pretends to be telling a story, as she might tell a story about something that really happened. We pretend to believe she's telling a story.Srap Tasmaner

    Hmm, I'm not sure if I like the way you phrased this, but I see what you are saying. Something like, "The author pretends to be telling a non-fiction story." At the end of the day I think it will depend a great deal on what an author is actually doing, which is obviously tricky.

    (I think it's a pretty sophisticated thing, and it's easy to be culture-bound and miss how unusual it is.)Srap Tasmaner

    Yes, and it is interesting that in recent history fiction was thought to require a kind of disbelief-suspension-bridge (I forget the real name that is used). Some plausible device was used to connect the fiction to the real world.

    Then, to take an extreme example, what did Tolkien take himself to be doing in his writings? He certainly seemed to be self-consciously involved in a less fictional act than, say, J. K. Rowling.

    A relevant (for this thread) question might be: what exactly is an author pretending to do that he isn't? Can we say, there's the sentences you speak and the order you speak them in, on the one hand, and something else that makes your speaking "reporting a sequence of events" or "(merely) telling a (fictional) story" on the other?Srap Tasmaner

    Right: Or: if telling a non-fiction story is a form of assertion, and telling a fiction story is not really assertion, then what is it? Frege talks about a similar thing in terms of the words of an actor on stage, and Kimhi considers this scenario (...in some earlier post I talked a bit about this). But what exactly constitutes the pretense in the author or kindergarten teacher who tells a fictional story? I'm not sure - haha.
  • A challenge to Frege on assertion


    That seems reasonable. Granted, I am a little bit surprised that Kimhi is so fond of the early Wittgenstein. I don't think a picture is a fact, and so I think the search for a fact-fact relation is a false start. I haven't read much where Kimhi speaks about consciousness and self-consciousness, but it seems plausible to me that he wants to move that relation away from world-facts and into the realm of consciousness. It seems clear that Kimhi accepts a logical subject in the way that (early?) Wittgenstein does not, and can thus introduce consciousness in a way that Wittgenstein could not.

    The more natural move for later Wittgenstein is to say that sometimes we see something as a picture of something else, sometimes we don'tSrap Tasmaner

    Yes, and if this weren't true then I don't see how we would be able to err. Then: is an inference—the thing between the lines of a syllogism—a kind of picture and also quasi- or sub-assertion? If so, and if a correct inference is a logical truth, then the possibility of inferential error comes into view.

    I suppose this is a somewhat new topic, but the thread is now becoming more diffuse. Are logical errors possible without [judgment, or a logical subject, or content to be judged]? Do those who fundamentally disagree with Frege's judgment-approach have any basis with which to account for logical errors?

    I must be missing something. I can see no more of a problem with fictional assertions than I can with fictional imaginings, fictional events, fictional places, fictional characters and so on.Janus

    I finished the Scholastic portion of Novak's paper, and I think I agree with you. It gets complicated, but I would essentially say that we can truly speak about fiction so long as the authors of fiction are genuine sub-creators (in Tolkien's sense). That is, we must say that in writing their books the authors of fiction create real truthmakers (or at least the sort of truthmaker that is proper and relevant to fiction).
  • A challenge to Frege on assertion
    I feel like I'm stuck in an Abbot & Costello routine! If this really represents what Frege would say to me when I ask him whether he comprehends the word printed on that slip of paper he found on the beach, I could only reply, "Well, yeah, but Herr Frege, I'm not asking about extension or objects or what's permissible or impermissible in your philosophy. Have pity on a fellow beachcomber and just tell me whether you understand the word on the paper or not."J

    It is an Abbot & Costello routine. You've been given my testimony, Srap's testimony, Kimhi's testimony, and the testimony of Frege himself, but you still refuse to believe. On what grounds? Frege will not find meaning where there is no extension.

    The answer here is that Frege reads the word through his understanding, and his understanding of meaning and truth has to do with the extension of predicates. It makes no sense for you to ask Frege what he would say about a piece of language without appealing to his understanding of language.

    The judgment stoke occurs once in the expression, at the beginning. It affirms the whole expression, not each individual line separately.Banno

    It can only occur once for an expression, but the question is whether a modus ponens is a single expression. What you said earlier simply does not hold:

    Frege doesn't write
    ⊢p⊃q
    ⊢p
    ⊢q
    such that each is within it's own intensional bracket; he writes
    ⊢(
    p⊃q
    p
    q)
    Banno

    My bolding.Banno

    As usual, you are failing to understand the sources you cite. "The judgment-stroke applies to the whole expression, therefore Frege does not use three judgment strokes in a modus ponens." This is a non sequitur.

    Here is Rombout, building from my post <here> and Bongo Fury's insight:

    Instead of writing the whole inference, consisting of the three assertions “ ⊢ p”, “ ⊢ (p ⊃ q)” and “ ⊢ q” , Russell and Whitehead propose an abbreviation containing the assertions of the two atomic propositions connected by an implication: “ ⊢ p ⊃⊢ q”. Frege would consider this a category mistake; in the Begriffsschrift it is not possible to have a judgment stroke within the scope of a conditional.

    ...

    A reason why Russell and Whitehead consider this abbreviation acceptable can be found in their explanation of syllogisms:

    <<It should be observed that syllogisms are traditionally expressed with ‘therefore’, as if they asserted both premises and conclusion. This is, of course, merely a slipshod way of speaking, since what is really asserted is only the connection of premises with conclusion.[36]>>

    Where in Frege the premises and the the conclusion, as well as the connection between them need to be asserted in order to constitute an inference, this demand is dropped [by Russell and Whitehead]. What is asserted in [Russell's] syllogism is the connection between premises and the conclusion, not the sentences themselves. This seems to be an explanation for allowing for an abbreviated form, but in order to conclude so, it has to be considered whether a syllogism is an inference.
    Rombout, 44-5

    One can speak about modus ponens in terms of logical consequence or logical inference. Both make sense in their own context, but Frege actually adopts the latter approach. For Frege a modus ponens requires three judgment-strokes.

    You continue unabated in your conflation of Frege and your own approach. You are making the exact same interpretational errors that Russell and then Wittgenstein made regarding Frege.
  • A challenge to Frege on assertion
    As I understand it, 0th level terms - a,b,x - name individuals. Included amongst those individuals are propositions, which in turn name a truth value. So (2+2=4)=(5-3=2)= ⊤. These all name the same individual. So "Berlin" might name the city, and "2+2=5" might name the false.

    ...

    On this account, both "Berlin" and "2+2=4" are names.
    Banno

    This is close, but it obscures the fact that "Berlin" correlates to "2+2" (or "4") and "Berlin is a city" correlates to "2+2=4." The latter two have truth values, and can be called names in reference to "the True." If I recall, in the source that Bongo Fury gave, on the pages following the citation he gave, Anscombe critiques this understanding of number.

    Now does Frege think that "4" and "2+2=4" are both 0th level terms, as Banno implies? I actually don't think he does, but I suppose it's possible. He certainly understands that something which saturates a predicate like "...is a city," differs from something which "saturates" the predicate, "...is the True." He distinguishes between objects and sentences, even if sentences are objects vis-a-vis the True in a certain sense.
  • A challenge to Frege on assertion
    From the other side, once you "grasp" the truth of a situation, have you any choice but to affirm it? This would seem to be somewhat closer to the sense of assertion intended. In other words, Moore's paradox is a simple impossibility: to see the truth of a situation or a proposition is to believe it.Srap Tasmaner

    That seems right to me.

    But I want to make a bit of a different point. On my (admittedly limited) understanding of the Tractatus, one thing a picture is entirely incapable of depicting is that it is true. A picture can show how things might be, and things may indeed be that way, but the picture cannot include itself in its depiction and vouch for its own accuracy.

    Just so, my belief that a picture is accurate does not count as evidence that it is.
    Srap Tasmaner

    Okay, and I agree that this seems accurate.

    We have talked some -- whether we should have or not, I'm not sure --- about whether there's some sense in which propositions are self-asserting. In these terms, whether a picture at least inherently claims that things stand as it shows, even if it cannot itself substantiate that claim.Srap Tasmaner

    That seems to be what Kimhi is saying:

    After a close read of Kimhi's section 2.5 I see him doing the exact same thing that Srap and I were doing. He says that both a declarative sentence and an asserted declarative sentence "display" force, but whereas the first is "a mere display" the second is "a self-identifying display."Leontiskos

    So that we then have:

    ...what is Kimhi trying to argue here?

    Simply working from Boynton, he seems to be saying that if the declarative sentence, "The cloud is raining," does not display an assertion, then it is impossible to say under what conditions the cloud would be raining or not raining. That if "the cloud is raining" and "the cloud is not raining" do not display different assertions, then they could not be associated with different truthmakers. This looks like the same argument that Wittgenstein gives in Rombout 60-62.
    Leontiskos

    So for Kimhi it is more than a matter of possible worlds. For Rombout this is also true in some sense for Wittgenstein:

    That is what Wittgenstein tries to show by means of this analogy: the difference between (Wittgenstein’s conception of) Fregean assertion and Wittgenstein’s own idea of a sentence saying that its Sinnw is true. In Tractatus a sentence cannot take a meta-position and compare the Sinnw it shows with the world. Therefore, the sentence cannot acknowledge its own truth. A sentence cannot ‘check’ whether it corresponds to the world and decide upon the truth of the claim it makes, there are no extra-linguistic acts attributed to sentences. Nevertheless, every sentence aims at truth. A sentence is a picture of reality and as such it already makes a claim about what reality looks like. That is what 4.022 expresses: a sentence depicts a situation and says that this situation is the case. Sentences are not completely neutral phenomena; in showing a situation, they already ‘support’ that situation. It would be incorrect to ascribe intentions to sentences, but a sentence depicts a possibility and embodies that possibility in the same time: the possibility may in fact not obtain, but the ‘proposal’ the sentence makes is that it does obtain. In representing a possibility, the sentence more or less puts the truth of this possibility under consideration.

    <<4.2 The meaning of the sentence is its agreement or disagreement of the possibilities of the existence and non-existence of states of affairs.>>

    It is not asserted in the Fregean sense, for this agreement is not assertion. Whether it is actually true, or whether it corresponds to reality, seems to be irrelevant to Wittgenstein, at least for logical considerations. It may be part of the natural sciences or of interest to someone, but it is not relevant when formulating the limits of our thought. The actual truth of a sentence can only be established by a subject, and it is already mentioned that a subject does not belong to logic.

  • A challenge to Frege on assertion


    An account of what? First you say, "unless these philosophers explain WHY thought MUST reflect reality..." And then you go on to speak about "accounts." They are two very different things. A necessary argument with the conclusion that thought reflects reality is different from an account of thinking.

    Isn't it self-evident that if logic is to be meaningful then there must be some relation between thought and reality?Leontiskos

    You haven't answered this question. Are you saying that logic would be meaningful even if there were no relation between thought and reality?

    You seem to be saying, "Unless Kimhi gives a metaphysical proof for the basis of logic his book is not worth a dime." But that's not a reasonable challenge. All inquiry involves presuppositions, and "logic is a thing" is not a tendentious presupposition. Kimhi is saying, "We both agree that logic is a thing, but Frege's account doesn't account for this fact very well." It's not reasonable or relevant to come along and say, "Ah, but I won't grant that logic is a thing until you prove it!"
  • A challenge to Frege on assertion
    Unless these philosophers explain WHY thought MUST reflect reality (via "logic"), it doesn't seem to have any force to me, except as, ironically, unsupported assertions.schopenhauer1

    Isn't it self-evident that if logic is to be meaningful then there must be some relation between thought and reality? In any case, the context here is that Frege and Kimhi accept this as a mutual presupposition:

    The rules of logic always presuppose that the words used are not empty, that the sentences express judgements, that we are not playing with mere words.

    Lukáš Novák, Can We Speak About That Which Is Not?, 157-8
  • A challenge to Frege on assertion
    I want to highlight a few things in Owen Boynton’s first-rate essay/review on Thinking and Being.J

    I would say that this is the most relevant part of Boynton's review for this thread:

    For any proposition, Pa, its truth value is associated with the extensional reference to something that exists (the extension is a relation between a and a fact in the world that must obtain). But what is it that creates this “association”? How is it associated with the extensional reference to something that exists, as opposed to something that does not exists?

    “In virtue of what is the forceless combination Pa associated with the truth-making
    relation that a falls under the extension of P, and thus with the claim Pa, rather than
    with the truth-making relation that a does not fall under P (or falls under the extension
    of ~P), and this with the opposite claim ~Pa? This question cannot be answered, since
    Pa does not display an assertion, and therefore there is nothing that associates it with
    the positive rather than the negative judgment.” (Kimhi, 137)

    Interestingly, this, coming near the end of Kimhi’s work, is very much where Rödl starts out in Self-Consciousness and Objectivity (p. 43: “But this second-order judgment is not a thought of its own validity. So I am not, in judging that I must judge q, conscious of anything that stands in the way of judging that I may judge ~q. And this is to say that I am not conscious of anything that stands in the way of judging ~ q.”);. . .
    Boynton's Review of Thinking and Being

    As I said above, I don't see Frege saying that Pa cannot display an assertion. Be that as it may, what is Kimhi trying to argue here?

    Simply working from Boynton, he seems to be saying that if the declarative sentence, "The cloud is raining," does not display an assertion, then it is impossible to say under what conditions the cloud would be raining or not raining. That if "the cloud is raining" and "the cloud is not raining" do not display different assertions, then they could not be associated with different truthmakers. This looks like the same argument that Wittgenstein gives in Rombout 60-62.

    Cf:

    It's tricky to switch paradigms, but in Wittgenstein's paradigm the problem is that Frege has "two phases in the assertion of a sentence." Russell struggles with the same issue from a different paradigm. For Frege it is the difference between "the True" and the judgment-stroke.

    To try to put it plainly: is it possible to see that something is true before going on to assert it? And does (the recognition of?) a sentence's truth require a subject? Is the syncategorematicity (in Boynton's sense) of the judgment-stroke already present in the truth-assessment?

    The puzzle is explicit in Frege's requirement that only true sentences can be asserted, a requirement that is incomprehensible to, and thus not even understood by, Russell and Wittgenstein. If only true sentences can be asserted, then what exactly is the difference between calling a sentence true and asserting it? Frege has an uncommonly objective notion of truth (and also assertion) (at least as far as contemporary logic is concerned).

  • Why should we worry about misinformation?
    I note that many of the fears over misinformation mention the threat to some amorphous, ill-defined order. Both China and the EU have this in common. From the EU, “The risk of harm includes threats to democratic political processes, including integrity of elections, and to democratic values that shape public policies in a variety of sectors, such as health, science, finance and more.” Or for China it threatens to “undermine economic and social order”. It’s clear to me that it is a threat to the state. Therefor, digital authoritarianism and the control of information is required.NOS4A2

    Interestingly, for Aristotle democracy is inherently unstable, especially in the direction of populism. So is a democracy that is safeguarded from "threats to democracy" still a democracy? Is democracy a threat to democracy?

    The irony here is that calls for censorship meant to safeguard democracy from threats to democracy are themselves a threat to democracy, and this seems fairly uncontroversial. At the end of the day a kind of theocracy with science or some other truth-approach at the helm is not democracy.
  • A challenge to Frege on assertion
    Put differently, in asserting, "If p then q," we are asserting something about p and q. Is the takeaway then that assertoric force is not binary? And yet, is assertion binary?
    — Leontiskos

    An interesting question. "If p then q" seems to be inherently an assertion about the relationship between p and q. It is an inherently asymmetric relation: "if q then p" is not entailed.

    "It is raining" has the form "x is y", just as "it is green" does, and yet they are not the same. To state that it is raining, I could just say "raining", which would seem to indicate that assertion is not always binary.

    I hope I've understood your question; I'm pretty confident about working out the logic of natural language, but I'm not great with formal logic.
    Janus

    It's more about intention than words. If you say "Raining," is your utterance necessarily either an assertion or a non-assertion? Or is there something inbetween? Srap is asking a similar question:

    ...Just so, I'm resistant to analysis that treats all of our declarative utterances as deserving an "I judge that ..." or "I believe that ..." in front of them. Sometimes we judge, sometimes we go out of our way to mark what we're saying as our personal belief, and sometimes, probably mostly, we just talk.Srap Tasmaner

    Is there then something between assertion and non-assertion?

    I still don't know what this thread is about, but I'm pretty sure it starts in a place pretty far from me and goes in the opposite direction.Srap Tasmaner

    I was trying to think of a way to put the exact same thing, and you've captured it perfectly. Most of the posters in this thread would say that Frege is too fat. Kimhi is arguing that he is too thin.
  • A challenge to Frege on assertion
    OK. Evidently my choice of “The grass in my backyard” was unfortunate, because it looks like its grammar may confuse the logical point. Let’s change the term to “Berlin”. If I say “Berlin,” I doubt if anyone would call it an incomplete sentence. Or, if you like, imagine Frege walking along a beach and finding a scrap of paper with the word “Berlin” written on it. In either of these cases, I’m guessing the natural response would be something like “What about Berlin?” or “I wonder why ‛Berlin’ appears here.” But what my question about comprehension is asking to you to affirm, is that in neither case would the response be “What is Berlin? I don’t understand this term” (if you’ll grant that the folks involved have heard of Berlin before).J

    Everything I said in my last post applies exactly the same here, as "Berlin" is no more a complete sentence than, "The grass in my backyard." See especially where Kimhi addresses the exact questions you are asking, as noted in my last post.

    To the second quote: I do indeed want to talk about (in the sense of "mention") some x apart from any function. I’ve just done so. You say that “Frege will not have it.” That may well be true. But again, what I’m asking is, does “not having it” mean that Frege doesn’t comprehend the term “Berlin”, or doesn’t think that I do? Or is it, rather, that he’s urging me to understand that I can’t say anything about the term without its taking its place to saturate a function?J

    Here is what Frege would say:

    Does "Berlin" have extension? If it does then it is not an object. If it does not then it is an object. All you are doing is trying to have it both ways. You want objects with inherent extension, which is impermissible.

    Natural language is not Fregian. I'm not sure what else to tell you. For the Aristotelian this is no problem given that grammatical subjects have inherent form.

    ...of course, this is not prima facie insurmountable for Frege. So "Berlin" involves a concept-function. So what?

    Leontiskos

    Note that even in this post (and earlier posts) first-order logic creates a concept-function out of the subject. This is not controversial; it is just how first-order logic is done. That logic does not permit something like this: ∃(grass)(Green(grass)). Objects do not have inherent extension.
