  • "What is truth? said jesting Pilate; and would not stay for an answer."
    I seem to recall, someone had a theory about that.bongo fury

    :up:

    Which one, right ?

    Rorty was maybe the first analytic philosopher I got into...bad influence, right ? Of course he challenged (as you prob. know) the 'mirror' or lens' or 'truth-o-scope' framework generally. Words are just paws for coping.
  • "What is truth? said jesting Pilate; and would not stay for an answer."
    The meaning of a proposition remains a representation of reality, at least an attempt at it. It's not the reality it tries to depict.Olivier5

    My question is: how does (the meaning of ) a true statement depict reality ? What is this representational, optical metaphor doing or trying to do ?

    "The internal"; my thoughts, feelings and bodily sensations are what is most immediately present to me. ... None of this has anything to do with Descartes.Janus



    Descartes famously emphasized that subjective reality is better known than objective reality, but knowledge of the objective reality of one’s own existence as a non-physical thinking thing is nearly as basic, or perhaps as basic, as one’s knowledge of the subjective reality of one’s own thinking. For Descartes, knowledge seems to start with immediate, indubitable knowledge of one’s subjective states and proceeds to knowledge of one’s objective existence as a thinking thing. Cogito, ergo sum (usually translated as “I think, therefore I am”) expresses this knowledge. All knowledge of realities other than oneself ultimately rests on this immediate knowledge of one’s own existence as a thinking thing.

    From the horse's mouth (and he is/was a genius) :
    Now that I have convinced myself that there is nothing in the world – no sky, no earth, no minds, no bodies – does it follow that I don’t exist either? No it does not follow; for if I convinced myself of something then I certainly existed.

    But there is a supremely powerful and cunning deceiver who deliberately deceives me all the time! Even then, if he is deceiving me I undoubtedly exist: let him deceive me all he can, he will never bring it about that I am nothing while I think I am something. So after thoroughly thinking the matter through I conclude that this proposition, I am, I exist, must be true whenever I assert it or think it.

    But this ‘I’ that must exist – I still don’t properly understand what it is; so I am at risk of confusing it with something else, thereby falling into error in the very item of knowledge that I maintain is the most certain and obvious of all. To get straight about what this ‘I’ is, I shall go back and think some more about what I believed myself to be before I started this meditation.

    Well, then, what did I think I was? A man. But what is a man? Shall I say ‘a rational animal'? No; for then I should have to ask what an animal is, and what rationality is – each question would lead me on to other still harder ones, and this would take more time than I can spare.
    ...
    Since now I am pretending that I don’t have a body, these are mere fictions. Sense-perception? One needs a body in order to perceive; and, besides, when dreaming I have seemed to perceive through the senses many things that I later realized I had not perceived in that way.
    ...
    Thinking? At last I have discovered it – thought! This is the one thing that can’t be separated from me. I am, I exist – that is certain. But for how long? For as long as I am thinking. But perhaps no longer than that; for it might be that if I stopped thinking I would stop existing; and I have to treat that possibility as though it were actual, because my present policy is to reject everything that isn’t necessarily true. Strictly speaking, then, I am simply a thing that thinks – a mind, or intelligence, or intellect, or reason, these being words whose meaning I have only just come to know. Still, I am a real, existing thing. What kind of a thing? I have answered that: a thinking thing.

    Well, then, what am I? A thing that thinks. What is that? A thing that doubts, understands, affirms, denies, wants, refuses, and also imagines and senses.

    Isn’t it one and the same ‘I’ who now doubts almost everything, understands some things, affirms this one thing – namely, that I exist and think, denies everything else, wants to know more, refuses to be deceived, imagines many things involuntarily, and is aware of others that seem to come from the senses? Isn’t all this just as true as the fact that I exist, even if I am in a perpetual dream, and even if my creator is doing his best to deceive me? These activities are all aspects of my thinking, and are all inseparable from myself. The fact that it is I who doubt and understand and want is so obvious that I can’t see how to make it any clearer. But the ‘I’ who imagines is also this same ‘I’. For even if (as I am pretending) none of the things that I imagine really exist, I really do imagine them, and this is part of my thinking. Lastly, it is also this same ‘I’ who senses, or is aware of bodily things seemingly through the senses. Because I may be dreaming, I can’t say for sure that I now see the flames, hear the wood crackling, and feel the heat of the fire; but I certainly seem to see, to hear, and to be warmed. This cannot be false; what is called ‘sensing’ is strictly just this seeming, and when ‘sensing’ is understood in this restricted sense of the word it too is simply thinking.
    — Descartes

    This is basically a 'speculative' theological vision. Descartes 'is' 'thinking' or language. It's our being jointly 'enworldled' and 'enlanguaged' that is 'given.' Descartes and Kant seemed to have got tangled up in the 'I' and its social function. 'I think' is attached to 'P' within a normative, scorekeeping game. But 'P' is is,in its intelligibility even to its user, prior to that user, deeper than that user. Descartes implicitly asserts the autonomy of reason by striving toward presuppositionlessness. So I claim, and so I claim Hegel and Heidegger claim, to name just two. The assault on the Cartesian subject is, as I understand it, one the big events in relatively recent philosophy.

    Taken as an intelligible (geistig) or an abstract being, that is, regarded neither as human nor as sensuous, but rather as one that is an object for and accessible only to reason or intelligence, God qua God is nothing but the essence of reason itself. But, basing themselves rather on imagination, ordinary theology and Theism regard him as an independent being existing separately from reason. Under these circumstances, it is an inner, a sacred necessity that the essence of reason as distinguished from reason itself be at last identified with it and the divine being thus be apprehended, realised, as the essence of reason. It is on this necessity that the great historical significance of speculative philosophy rests. The proof of the proposition that the divine essence is the essence of reason or intelligence lies in the fact that the determinations or qualities of God, in so far as they are rational or intelligible and not determinations of sensuousness or imagination, are, in fact, qualities of reason.

    “God is the infinite being or the being without any limitations whatsoever.” But what cannot be a limit or boundary on God can also not be a limit or boundary on reason. If, for example, God is elevated above all limitations of sensuousness, so, too, is reason. He who cannot conceive of any entity except as sensuous, that is, he whose reason is limited by sensuousness, can only have a God who is limited by sensuousness. Reason, which conceives God as an infinite being, conceives, in point of fact, its own infinity in God. What is divine to reason is also truly rational to it, or in other words, it is a being that perfectly corresponds to and satisfies it. That, however, in which a being finds satisfaction, is nothing but the being in which it encounters itself as its own object. He who finds satisfaction in a philosopher is himself of a philosophical nature. That he is of this nature is precisely what he and others encounter in this satisfaction. Reason “does not, however, pause at the finite, sensuous things; it finds satisfaction in the infinite being alone” – that is to say, the essence of reason is disclosed to us primarily in the infinite being.
    ...
    The necessary being is one that it is necessary to think of, that must be affirmed absolutely and which it is simply impossible to deny or annul, but only to the extent to which it is a thinking being itself. Thus, it is its own necessity and reality which reason demonstrates in the necessary being.

  • "What is truth? said jesting Pilate; and would not stay for an answer."
    The same applies to many objects, including material ones.Olivier5

    :up:
  • "What is truth? said jesting Pilate; and would not stay for an answer."
    I personally see truth as a property of certain sentences and other symbolic representations of reality, the property of having a good enough fit with said reality, as far as we can tell.Olivier5

    That view is tempting, but I can't make sense of the comparison, of the fit. Only one side is intelligible.

    We clearly aren't fitting strings of letter to reality but the 'meaning' of the utterance. Yet the 'meaning' is just the more or less tentatively embraced 'structure of reality.' It's as if world-as-speakable and language are one, but that's a tautology...(?)

    How do you make sense of fit ? Do you see a problem ?
  • Our Minimal Epistemic Commitment (Fixing Descartes' Cogito)
    @Janus
    Here are some Dreyfus-translated passages from Heidegger (from Being-in-the-World). I recommend especially the chapter "The Who of Everyday Dasein."

    While it's beyond the minimal epistemic given to just assert these things, I read them as gesturing toward something similar, toward our being-in-a-world-in-language-together as our basic human situation. I am not some ghost viewing a spectacle. That's an example of 'interpretedness,' which is to say historical baggage, taken for granted unquestioningly.
    /////////////////////////////////////////////////////////////////////////////////////////////////
    The one as that which forms everyday being-with-one-another...constitutes what we call the public in the strict sense of the word. It implies that the world is always already primarily given as the common world. It is not the case on the one hand there are first individual subjects which at any given time have their own world; and that the task would then arise of putting together, by virtue of some sort of arrangement, the various particular worlds of individuals and of agreeing how one would have a common world. This is how philosophers imagine these things when they ask about the constitution of the inter-subjective world. We say instead that the first thing that is given is the common world -- the one.
    ...
    Dasein, in so far as it is, has always submitted itself already to a 'world' which it encounters, and this submission belongs essentially to its being.
    ...
    Primarily Dasein is 'one,' and remains so.
    ...
    As a "one's self," the particular Dasein has been dispersed into the 'one' and must first find itself.
    ...
    "[The one] is the 'realest subject' of everydayness."
  • Our Minimal Epistemic Commitment (Fixing Descartes' Cogito)
    "The internal"; my thoughts, feelings and bodily sensations are what is most immediately present to me. Your thoughts, feelings and sensations are present to me only insofar as they can be conveyed by what you say about them: if you are being honest. If you are lying or hiding your thoughts and feelings then I may have no idea; unless I feel your actions are giving you away, and I could be wrong about that. None of this has anything to do with Descartes.Janus

    From Wiki:
    Subjectivism is a label used to denote the philosophical tenet that "our own mental activity is the only unquestionable fact of our experience." The success of this position is historically attributed to Descartes and his methodic doubt.

    As a reader of Heidegger, you may find this relevant. (I prefer it from the horse's mouth, but I'm not going to type up piles of prose for something so established.)

    Descartes stands at the beginning of modern philosophy and Heidegger accepts Descartes' role in the history of metaphysics. Descartes is the first thinker who discovers the "cogito sum" as an indubitable and the most certain foundation and thereby liberates philosophy from theology. He is the first subjectivistic thinker in the modern philosophy and he grounds his subjectivity on his epistemology.

    The orientation of the philosophical problems with Descartes starts from the "ego" (the "subject") because in the modern philosophy the "subject" is given to the knower first and as the only certain thing, i.e., the only "subject" is accessible immediately and certainly. For Descartes, the "subject" (the "ego", the "I", "res cogitans") is something that thinks, i.e., something that represents, perceives, judges, agrees, disagrees, loves, hates, strives, and likes. "Descartes calls all these modes of behavior cogitationes." (1) Therefore, "ego" is something that has these cogitationes. However, the cogitationes always belongs to the "I", I judge, I represent, etc. Heidegger maintains that Descartes' definition of "res cogitans" says to us that "res cogitans" is a res whose realities are representations.
    ...
    Starting with Descartes, the subject becomes the center, and the subject, as the first true being, has priority over all other beings. Contrary to this priority of the subject, Heidegger's goal is to show that there is no subject distinct from the external world of things, because Dasein is essentially Being-in-the-world. Therefore, Heidegger puts together the separation of the subject and the object by the concept of "Dasein" which is essentially a Being-in-the-world. However, Being-in-the-world does not mean that it is like a piece of chalk in the chalk box. Being-in, as the most essential and existential characteristics of Dasein, signifies the expression of such terms as "dwelling," "being familiar with," and "being present to."

    The distinction between the subject and the object makes the possibility of the distinction between the knower and what he knows.

    To head off any confusion, let me be clear that I'm in earnest. I don't intend sarcasm or rudeness. Here's my view of the situation.

    You say you are right where all philosophers up till now are wrong...on an important issue. That's a strong claim, for which a strong case ought to be made. Note that I think talk of models already saves those philosopher from being wrong. We don't have to know or claim to know the secret hearts of cats or amoeba to postulate entities useful for predicting them. [Indeed, I think we agree that such a secret 'inside' is useless.]

    How ought we to think of belief in languageless creatures ? The way I'm tracking things, you've said not-this-way and not-that-way. But where's the positive, 'operational' definition, however tentative ?

  • "What is truth? said jesting Pilate; and would not stay for an answer."
    I definitely need that explained.bongo fury
    This is pretty good.
    In computer science, a pointer is an object in many programming languages that stores a memory address. This can be that of another value located in computer memory, or in some cases, that of memory-mapped computer hardware. A pointer references a location in memory, and obtaining the value stored at that location is known as dereferencing the pointer. As an analogy, a page number in a book's index could be considered a pointer to the corresponding page; dereferencing such a pointer would be done by flipping to the page with the given page number and reading the text found on that page.

    Quoting/mentioning is something like pointing at sentence-as-meant. Deferencing is like quote-stripping, 'activating' the code.

    I just meant that we can still drop "proposition".bongo fury

    I probably just muddied the water by mentioning pointers.
  • "What is truth? said jesting Pilate; and would not stay for an answer."

  • "What is truth? said jesting Pilate; and would not stay for an answer."

    You may be right, but I don't think I'm that wrong.

    Philosophers looking for some underlying nature of some truth property that is attributed with the use of the expression ‘true’ are bound to be frustrated, the deflationist says, because they are looking for something that isn’t there.
    ...
    The suggestion that there is no truth property at all is advanced by some philosophers in the deflationary camp; we will look at some examples below. What makes this position difficult to sustain is that ‘is true’ is grammatically speaking a predicate much like ‘is metal’. If one assumes that grammatical predicates such as ‘is metal’ express properties, then, prima facie, the same would seem to go for ‘is true.’ This point is not decisive, however. For one thing, it might be possible to distinguish the grammatical form of claims containing ‘is true’ from their logical form; at the level of logical form, it might be, as prosententialists maintain, that ‘is true’ is not a predicate.

  • "What is truth? said jesting Pilate; and would not stay for an answer."
    I dispute the point that propositions are nonlinguistic and timeless entities.Olivier5

    :up:

    We should perhaps acknowledge a Derridean 'iterabilty' at work, which is what suggests 'timeless' to earlier theorist (there's a certain time-independence, since old books remain legible, we can quote Tarski in a new context,...)

    ‘Iterability’ explains that Derrida is concerned with the logical possibility — not merely the physical opportunity — for a written text to remain readable when the absence of the sender or the addressee is no longer a mode of presence but a radical or absolute absence. He sees the possibility of it functioning again beyond (or in the absence of) the ‘living present’ of its context of production or its empirically determined destination as part of what it is to be a written mark. We can thus propose this ‘law of writing’: a mark not structurally readable — iterable — beyond the death of the empirically determinable producer and receiver would not be writing.

  • "What is truth? said jesting Pilate; and would not stay for an answer."
    Both, because propositions are in fact a class of sentences.Olivier5

    Or perhaps neither ? We deny that truth is a property. "P is true" is a fancy/emphatic version of "P."
  • Our Minimal Epistemic Commitment (Fixing Descartes' Cogito)

  • Our Minimal Epistemic Commitment (Fixing Descartes' Cogito)
    I think the notion of normative rationality is a form of scientism;Janus

    I think you know not what you say. Or maybe you really are an irrationalist. There are some fun versions of it.

    Enlightenment is the human being’s emergence from his self-incurred immaturity. Immaturity is the inability to use one’s own understanding [= reason] without the guidance of another. This immaturity is self-incurred if its cause is not lack of understanding, but lack of resolution and courage to use it without the guidance of another. Sapere aude! [Dare to be wise!] Have courage to make use of your own understanding [= reason]! is thus the motto of enlightenment.

    It is requisite to reason’s lawgiving that it should need to presuppose only itself, because a rule is objectively and universally valid only when it holds without the contingent, subjective conditions that distinguish one rational being from another.
    ...
    Reason must subject itself to critique in all its undertakings, and cannot restrict the freedom of critique through any prohibition without damaging itself and drawing upon itself a disadvantageous suspicion. For there is nothing so important because of its utility, nothing so holy, that it may be exempted from this searching review and inspection, which knows no respect for persons [i.e. does not recognize any person as bearing more authority than any other—GW]. On this freedom rests the very existence of reason, which has no dictatorial authority, but whose claim is never anything more than the agreement of free citizens, each of whom must be able to express his reservations, indeed even his veto, without holding back. (A738f/B766f, translation slightly modified)
    ...
    To make use of one’s own reason means no more than to ask oneself, whenever one is supposed to assume something, whether one could find it feasible to make the ground or the rule on which one assumes it into a universal principle for the use of reason.

    [N]ot even the slightest degree of wisdom can be poured into a man by others; rather he must bring it forth from himself. The precept for reaching it contains three leading maxims: (1) Think for oneself, (2) Think into the place of the other [person] (in communication with human beings), (3) Always think consistently with oneself.

    But who would say otherwise ? Is the Enlightenment to be understood as more of a prison than a release ?

    I think Heidegger was very concerned about authenticity, about living one's life and thinking one's thoughts in accordance with individual experience, judgement and resolve, not following "das Man"; not doing and thinking "what One does".Janus

    It's as if you think I'm advising human beings to be thrown in interpretedness, to have prejudices they don't even know they have (co-revealed with the other in the interpretation thereof, as Gadamer described.) Given your seeming 'Cartesian' leanings, it's my opinion that you are missing some good stuff, which I locate in Dreyfus on 'the who of everyday dasein.' "Language speaks and not the human."
    It's not that the 'we' ought to have priority over the 'I.' It's more like the 'I' is an appendage. Language is the 'water' we swim in as 'spiritual' [cultural, self-made, historical] beings. We're in it as much as it's in us. That's my claim, anyway.

  • Foundational Metaphysics
    I would be interested to hear what you think!Bob Ross

    Hi ! I sometimes talk with people on forums who have various intuitions and suggestions about infinity and other mathematical concepts. Often enough they've had no experience writing mathematical proofs, which is like not knowing quite what math is, at least to a mathematician (even if, in fact, one can go a long way in applications without ever learning proofs.) 'Poetry' is a just a metaphor for these ideas that are not yet in mathematical shape. It's fair to expect some mastery of real analysis from an innovator. (Algebra and topology are natural mentions, but real analysis is the serious theory of the numbers we all are somewhat familiar with.)
  • Is there an external material world ?
    Not sure what "operational definition of this thinking" is asking for.creativesoul

    For instance, how does one detect/define consciousness ? If one rejects the idea of a mysterious X that makes the difference between an arbitrarily convincing P-Zombie and a 'Real Boy,' then we must have some threshold of recognition. In ordinary life, it'd be something like responsiveness (we could talk the details endlessly, but we wouldn't be worried about P-Zombies.)

    So how do you determine or grab a nonlinguistic belief ? Currently I can imagine attributing linguistic belief or a mathematical model.

    If belief is internal and external, it'd be hard to grab it, I'd think. How can one report it objectively ? Or is it merely postulated ?

    I think this is the natural way to think of it. But I take it to be one of the great discoveries of philosophy to have flipped things around. This flip, this revelation of the priority of the 'we' before the 'I' and the 'external' to the 'internal'...I take to be what's great in Wittgenstein and Heidegger. As I see it, one is one before one is someone in particular. Everyday Dasein is Anyone, tribal second nature incarnate.

    We can joke too. We do want to be machine men.

    People will always have differing worldviews: it's a phenomenon of natural diversity.Janus

    But this is obvious. Why should we worry about settling beliefs rationally in the first place if there weren't so many candidates to choose from ? It's because you and I and the other folks are free that we can ask for reasons, demand justifications for claims. Where we might agree is that a rational person can be a hypocrite or a fanatic. Is Ayn Rand a hero of rationality ? Quite the opposite in my view. A boxer gets in the ring, and philosopher suffers exposure to difference, tarries with the negative.
    Like Milton and Spinoza and Kant and others, I think free speech is crucial, so don't count me an enemy of diversity simply because I seek the best beliefs like everyone else.

    It is requisite to reason’s lawgiving that it should need to presuppose only itself, because a rule is objectively and universally valid only when it holds without the contingent, subjective conditions that distinguish one rational being from another.
    ...
    Reason must subject itself to critique in all its undertakings, and cannot restrict the freedom of critique through any prohibition without damaging itself and drawing upon itself a disadvantageous suspicion. For there is nothing so important because of its utility, nothing so holy, that it may be exempted from this searching review and inspection, which knows no respect for persons [i.e. does not recognize any person as bearing more authority than any other—GW]. On this freedom rests the very existence of reason, which has no dictatorial authority, but whose claim is never anything more than the agreement of free citizens, each of whom must be able to express his reservations, indeed even his veto, without holding back.

    — Kant

    The Peircean notion of the truth asymptotically approached by the "community of enquirers" is a sick fantasy; another sad attempt, like many religions, to devalue and stamp out our animal natures.Janus

    I think Peirce's idea is worthy, but my own view of truth, a descendant perhaps, is deflationary. I claim that the 'religion' metaphor is misleading. It's a bit absurd to conflate faith and rationalism. What's that leave you with ? What's your just-right porridge with so much proscribed ? Or do you insult reason to make room for faith as well as an unleashed animality ? Are we talking The Crucified or Dionysos ?

    I have received, sir, your new book decrying the human species, and I thank you.(1) You will please men, of whom you speak the truth, but you will not correct them. One cannot paint in stronger colors the horrors of human society, from which our ignorance and our weakness promise so many consolations. One has never taken up so much wit in wishing us all beasts--it gives us a desire to walk on all fours when we read your work.

    What is necessary for a philosopher to make sense? To speak coherently and in terms that anyone prepared to make the effort can understand,,,although obviously not necessarily agree with.Janus

    And that means the need a common-public language to be in together, which is to say [also] a common-public world for that language to be about. You left out normative rationality. The first two requirements (arguably just one language-world) are those for any kind of communication.

    That's what this thread might do, for some.Banno

  • Is there an external material world ?
    i just don't trust his book recommendations.Banno

    I may be more in the middle. There's great stuff in Heidegger and Derrida, two of his favorites, but I like dragging that stuff over toward a more analytic-friendly style.
  • Is there an external material world ?
    And how did the end of history work out? He's still trying to eff the ineffable.Banno

    Oh he's beautifully mad though. His Hegel is both cutting-edge and reactionary. It's like sci-fi. Yet I think much of it endures.
  • "What is truth? said jesting Pilate; and would not stay for an answer."
    I'm not so sure. I suspect it's actually pretty simple, if folk don't confuse themselves. Treat T-sentences as a definition of "...is true" and you won't go far wrong.Banno

    :up:

    I think we should make it simple in just way (or close enough.)
