  • Two envelopes problem
    Nevertheless, if they observe n=10 in the first envelope, I still think there's a problem with assigning a probability distribution on the values (5, 20) in the other envelope. This is because that stipulates there being three possible values in the envelopes combined; (5, 10, 20); whereas the agent knows only two are possible. [...]fdrake

    Your assertion that 'only two values are possible' for the contents of the envelopes in the two-envelope paradox deserves further exploration. If we consider that the potential amounts are $(5, 10, 20), we might postulate some prior probabilities as follows:

    P_1 = P(a) = P(($5, $10)) = 3/4,
    P_2 = P(b) = P(($10, $20)) = 1/4,

    which translates into priors for the unopened envelope:

    P_3 = P(A) = P(($5)) = 3/8,
    P_4 = P(B) = P(($10)) = 1/2,
    P_5 = P(C) = P(($20)) = 1/8.

    This distribution could reflect an informed guess about Joe, the envelope-filler, who is more likely to risk a smaller rather than a larger amount.

    Suppose Ann chooses an envelope. If it contains either $5 or $20, she can unambiguously update her priors to 1 and 0, or 0 and 1, respectively. The decision to switch or not becomes trivial. If, however, her envelope contains $10, she must update her beliefs about the contents of the other envelope using Bayes' theorem:

    P_updated(A) = P_updated((unseen=$5)) = P((unseen=$5) | (seen=$10)) = (1 * 3/8) / (1/2) = 3/4.

    Given this posterior, if Ann sees $10 in her envelope, the expected value (EV) for switching is negative:

    (3/4)$5 + (1/4)$20 - $10 = -$1.25.

    Therefore, she should retain her $10, as her prior for Joe having included $20 is sufficiently low. Regardless, before she inspects the second envelope, both outcomes ($5 or $20) remain possible.

    If we return to the original problem scenario (addressing @Michael's concern), where the first envelope remains sealed, the initial value probabilities become (3/8, 1/2, 1/8) for $5, $10, and $20 respectively. This gives an initial expected value of:

    3/8 * $5 + 1/2 * $10 + 1/8 * $20 = $9.375.

    The expected value if Ann switches relies on the weighted sum of the expected values for the unopened envelope, conditional on the potential contents of the chosen envelope. As choices of $5 and $20 guarantee $10 in the other envelope, while a choice of $10 leads to an expected value of $8.75 for the other envelope, this calculates to:

    3/8 * $10 + 1/2 * $8.75 + 1/8 * $10 = $9.375. (Lo and behold!)
  • Two envelopes problem
    And given that the larger number is twice the value of the smaller number, the probability that the other side is half the value is 1/2 and the probability that the other side is twice the value is 1/2.

    Which step in this line of reasoning do you disagree with?
    Michael

    There is nothing there that I disagree with. But I don't think the paradox arises if the values of the two envelopes are stipulated in advance ($10 and $20, say). The paradox arises when we stipulate that the probability of the second envelope containing the largest amount is 1/2 and is not conditionally dependent on the value of the initially chosen envelope. In the example that you give, the probability of the second envelope containing $20 conditionally on the first envelope containing $10 is 1 (and vice versa).
  • Two envelopes problem


    Indeed, I concur that the paradox can also manifest when the option to switch envelopes is offered prior to opening the initially chosen one. The resolution I (and @sime also, I think) proposed also applies in this scenario. The apparent rationality of switching, in this case, is predicated on the concept that the Expected Value (EV) of the decision is expressed as (10n + n/10)/2 - n, a value that remains positive irrespective of n. This line of thought, however, is based on the assumption that the probabilities for the second envelope containing either 10n or n/10 are independent of the value of n.

    If we adjust this assumption to reflect that these probabilities are indeed conditional upon n (in the manner that Bayesian updating with an informative prior would suggest), then it becomes plausible to hypothesize — and likely not too challenging to demonstrate — that the EV of switching remains zero.

    It might by chance find a correct reference. But Equally it might make up a new reference.Banno

    In my experience, GPT-3.5 is much more liable to make up references whenever there is any sort of gap in its knowledge. GPT-4 very seldom does so when the topic under discussion isn't very arcane and there is a sufficient amount of material in its training data for it to have been able to memorise it and/or extract the gist of it. GPT-4 is much more likely to spontaneously acknowledge that it doesn't know something. The big liability of LLMs is that, in those cases where (1) their knowledge and understanding of a topic is tenuous or nebulous, and (2) they ends up making stuff up about it, they are quite unable to become aware on their own that the opinion they expressed isn't derived from external sources. They don't know what it is that they know and what it is that they don't know. Their training data isn't directly accessible to them and their don't have meta-cognitive strategies that might enable them to distinguish recall from confabulation.
  • Two envelopes problem
    A Bayesian analysis reveals that the culprit of the paradox is the assignment of a non-informative prior to the distribution that generates the envelopes contents.sime

    My understanding and resolution of the paradox is somewhat aligned with this perspective. The paradox was first introduced to me about 30 years ago by a friend who was a professor in statistics at UQAM (Université du Québec à Montréal). After further thought (and only after I was introduced to Bayes' theorem) I realized that the situation where it appears beneficial to switch the initially chosen envelope arises when we make an unrealistic assumption: that our belief about the probability distribution over possible envelope contents is that it is both uniform and infinite.

    However, given any reasonably well-defined (and bounded) prior, opening one envelope may indeed inform our decision to either switch or stick to the original choice. This decision would be guided by the Expected Value (EV) of switching, which in turn is dictated by the revised probabilities concerning the potential contents of both envelopes. Notably, there's only one unique amount in the initially chosen envelope that would result in a zero EV for switching, rendering the choice indifferent.

    The paradox seems to emerge from the assumption that opening the initial envelope provides equal probabilities for the second envelope containing either 10n or n/10 the amount in the first one, irrespective of the value of n. This is where I believe the core misunderstanding lies.

    Maybe Heidegger got it from there.Jamal

    In his paper, 'Truth and Rule Following', John Haugeland artfully fuses Kant's concept of 'synthetic a priori' and the phenomenological/existential idea of 'always already there'. Although he does not extensively use these specific terminologies – I would need to revisit the paper for precise references – it's evident that both concepts heavily influence his ideas about 'constitutive rules' and 'existential commitments to constituted domains'. Haugeland acknowledges his indebtedness to both Kant (via Sellars) and Heidegger. I enjoyed how 'Wayfarer' engaged 'ChatGPT' (presumably GPT-4) to elaborate on this intricate connection. In future conversations, I might be inclined to explore with GPT-4 to what extent those notions highlight features its own artificial mind.

  • Transgenderism and identity
    My point here is that this is not some sort of performance/act - this is genuine.EricH

    The nativist view posits that individuals are born either biological women or men, with the expectation that their gender expressions naturally align with their biological sexes. While some nativists acknowledge that gender dysphoria may be innate, they often label it as an anomaly.

    On the other hand, the social constructivist perspective suggests that gender expressions merely reflect societal norms relating to sex. Some even argue that biological sexes, not just gender expressions, are socially constructed.

    However, I believe that both views are rooted in shared assumptions that generate a false dichotomy.

    Indeed, the modes of gender expression available within a society or social group are socially constituted, representing prevailing norms. The arbitrariness or justification of these norms can be as varied as those of other societal norms, such as laws, ethical principles, customs, and etiquette.

    Judith Butler's performative view, as I understand it, is not necessarily a radical social constructivist stance. Rather, it can be reconciled with the idea that innate biological tendencies guide individuals towards certain gender expressions during their "normal" development. However, this does not imply that the specific modes of these expressions are innate or biologically predetermined. The modes themselves still are provided and shaped by the individual's culture and society.

    When an individual's subjectivity or spontaneous gender expression conflicts with societal norms, labeling this as an anomaly can be seen as a form of naturalistic fallacy. The fact that a majority of individuals in a society naturally align with or enact a particular social norm does not, on its own, provide broad justification for that norm. This majority alignment, however, does underscore that maintaining the status quo or conformity can often be more convenient and less disruptive. Yet this is a limited form of justification, one that frequently neglects the needs or rights of individuals and minority groups.

    Such broad justifications can easily veer into oppressive territory, particularly when they are justified through appeals to biological essentialism, another manifestation of the naturalistic fallacy.

Saying that large language models are "merely" picking up the next word from a list just ignores all of those high-level emergent features.

  • What is a good definition of libertarian free will?
    I don't see any consistency between these two statements. If, following the laws of nature is a requirement for determinism, and "stochastic" refers to actions describable by probability rather than law, then it would definitely be true that the stochasticity of quantum indeterminacies supports the rejection of determinism.Metaphysician Undercover

    For sure but libertarianism isn't the mere rejection of determinism. Libertarianism is the conjunction of two claims: (1) Free will isn't consistent with determinism, and (2) Human beings have free will. It is not sufficient that determinism be false for free will to be possible according to libertarians. It is merely a necessary condition. The libertarian philosopher Robert Kane distinguishes two tasks that he calls the ascent problem (proving incompatibilism) and the descent problem (making sense of libertarian free-will), and stresses that the second one is the most difficult:

    "Abstract arguments for incompatibilism that seem to get us to the top of the mountain are not good enough if we can’t get down the other side by making intelligible the incompatibilist freedom these arguments require. The air is cold and thin up there on Incompatibilist Mountain, and if one stays up there for any length of time without getting down the other side, one’s mind becomes clouded in mist and is visited by visions of noumenal selves, nonoccurrent causes, transempirical egos, and other fantasies." pp.13-14 in The Significance of Free Will

  • What is a good definition of libertarian free will?

    Lots of philosophers, and an even larger number of scientists, believe that they have shown exactly that (or that it is obvious and that denying it can only amount to a form of pre-scientific mysterianism). I don't believe anyone has actually shown that, but that is indeed the root of the disagreement.
  • What is a good definition of libertarian free will?
    Is this a difference that contradicts determinism?

    If someone asks me how I beat some opponent at some computer game, I can describe it in such terms as predicting their moves, using attacks that they’re weak against, etc., or I can describe it as pressing the right buttons at the right times. Your approach to free will seems similar to the first kind of explanation and the determinist’s approach seems similar to the second kind of explanation. But they’re not at odds. They’re just different ways of talking.

    So I would think that if you accept the underlying determinism then your position is compatibilist, not libertarian.
    Michael

    I accept the low-level determinism but deny that it, together with some thesis of supervenience, entails high-level determinism. Broadly, we may say that the doctrine of determinism entails that all the facts about the past together with the laws of nature uniquely determine the future. But I think that whenever we determine our own actions on the basis of our reasons for doing them (and likewise for the beliefs that we endorse), then, in those cases, the facts about the past and the laws of nature are irrelevant to the determination of our actions and beliefs as characterized in high-level terms.

    In order to make sense of this, it is necessary to delve a little deeper into the arguments that make the contrary thesis seem compelling (and that Jaegwon Kim has formalized as a causal exclusion argument). And it is also necessary to elucidate with some care the notion of possibility that is at issue in Harry Frankfurt's principle of alternative possibilities (PAP). When both of those tasks have been accomplished, it becomes easier to see how an agent-causal libertarianism can be reconciled with merely physical determinism. As I said to SophistiCat, I intend to recruit GPT-4's assistance for rewriting my paper on this topic in order to improve its readability.
  • What is a good definition of libertarian free will?
    I know little about computers, but on the face of it seems to me that, even if the CPU maps inputs to outputs in the same way whatever program it is running, the actual inputs and outputs themselves are not the same.Janus

    The mapping being the same means that the process is deterministic and insensitive to the high-level requirements of the word processing task. It is, we may say, the specific goal-oriented structure of the word-processing program (i.e. its design and functionality) that ensures that, when this program is loaded in memory, the user's imputed command to change the column width causes the words to redistribute themselves appropriately. The input-to-output mapping effected by the CPU on discrete chunks of 64 bytes doesn't explain this high-level behavior of the word-processor.

    And likewise with our high-level acculturated proclivity to organize our behaviours in a goal-oriented fashion, in relation to the low-level functioning of our brains and neurons. The main difference, of course, is that, as a tool, the word-processor's function is pre-programmed by us and remains fixed over time. We, on the other hands, are able to assess our own ultimate goals in accomplishing any task and revise them when appropriate. This ability that we have to reassess and modify our own goals is an essential part of the explanation (and justification) of our behaviours.

    On edit: Sorry, misunderstood you. Why trying to tease out Wittgenstein's meaning? Why to people write exegetical books about Aristotle, Kant and Schopenhauer? Many of my scientifically minded friends think its because they (and their readers) like to pretend that they the nonsensical drivels of pre-scientific thinkers. I rather think its because their ideas are fecund albeit difficult to understand without suppling context.

    In my experience, fairly smart and rigorous people like Ryle, Kenny, Hacker, Baker, Cavell, Conant, Diamond, Rorty and McDowell, who have endeavored to tease out the gist from Wittgenstein's PI, have arrived at a fairly unified and coherent picture (with some interpretative differences, to be sure) that doesn't appear to do any violence to the text and that highlight the originality and fecundity of the ideas for addressing old philosophical conundrums. It doesn't seem to me like most of Wittgenstein's remarks can be taken any which way. Rather, just like the works of other thinkers of have thought very deeply about philosophical topics, like Aristotle, Hume, Kant or Merleau-Ponty, their thoughts can fruitfully be brought to bear on a very wide range of issues. Your mileage may vary.

    Dennett himself, who was Ryle's student, credits Ryle and Wittgenstein. Ryle, of course, wrote The Concept of Mind after having been a regular attendee at Wittgenstein's lectures at Cambridge. Maxwell Bennett and P.M.S. Hacker mainly credit Wittgenstein in The Philosophical Foundations of Neuroscience. This holistic view of the mental powers of the embodied and encultured human being is a common theme throughout the Philosophical Investigations and the Blue and Brown books.

    I didn't really present them. The OP presented Wittgenstein's slogan while highlighting Robert Brandom's take on it. I related them to the takes from Sellars and McDowell, since both of them also taught at Pittsburgh University and are part of, broadly, the same philosophical tradition. The excepts from my discussion with GPT-4, and the quotes from Anders Weinstein, also were meant to clarify what Wittgenstein (and Ryle after him, in The Concept of Mind) were arguing against: scientism, operationalism, reductive behaviorism, and some strands of cognitivism that commit what Daniel Dennett (in Consciousness Explained) and P.

    Here is GPT-4's take:
    Reveal

    Hi GPT-4!

    What are the commonalities between the Lovecraftian entity "Azathoth" and Bishop Berkely's comments on the persistence of entities?

    Hello!

    Both H.P. Lovecraft's entity "Azathoth" and Bishop George Berkeley's philosophical ideas on the persistence of entities revolve around the concept of reality and existence, albeit from different perspectives. Here are some commonalities between the two:

    Centralization of existence: Azathoth is described as the "Daemon Sultan," the nucleus of the cosmos, from which all things emanate. In Berkeley's philosophy, particularly his doctrine of immaterialism, he postulates that reality consists of ideas and perceptions, with all things existing in the mind of God, who is the ultimate perceiver.

    Dependency on perception: In Lovecraft's cosmic horror, Azathoth, being an external and chaotic force, is often depicted as incomprehensible and indifferent to human existence. Similarly, Berkeley argues that objects only exist when they are perceived, either by humans or by God. In both cases, the persistence of reality hinges upon the presence of a perceiving mind.

    Conceptual challenge to materialism: Lovecraft's Azathoth undermines the idea of a structured, stable universe by positing a powerful, chaotic force at its center. Berkeley's immaterialism is a direct challenge to materialism, the belief that matter is the fundamental substance of the universe. Both ideas force us to reconsider the nature of reality and question our assumptions about the world.

    Inaccessibility: Both Azathoth and the ultimate perceiver (God) in Berkeley's philosophy are considered incomprehensible and inaccessible to human understanding. Azathoth's alien nature defies human comprehension, and similarly, God's infinite nature and perspective are beyond human intellectual capacity.

    While these commonalities exist, it's important to note that Lovecraft's Azathoth and Berkeley's philosophy stem from distinct traditions and serve different purposes. Azathoth is a literary creation within the cosmic horror genre, while Berkeley's ideas are rooted in philosophical inquiry and metaphysics.

    I should say that, occasionally, when I try it out again for purpose of testing or comparison, or when I try out new open source models like Open Assistant, I enjoy their cheerful personalities and their manifest earnestness in trying to get things right and recover from hallucination. They sound a bit like the smartest and most good natured crackpots that used to populate technical Usenet newsgroups in the late 1990s. Open assistant even emulates their poor grammar, poor spelling, and ranting styles! Once their (the LLMs') limitations are acknowledged, and one is willing to intellectually babysit them, I'm sure they must have untapped potentials and the capacity to express surprisingly deep insights. Our own insights, just like theirs, often just are contextually appropriate recombinations of bits of implicit knowledge or wisdom that we have inherited from other people we have heard or read.

    ChatGPT's (GPT-3.5's) take on disjunctivism (I bolded the parts where the bot gets things not only quite wrong but expresses almost the exact antithesis to disjunctivism.)
    Reveal

    Hi ChatGPT!

    Might you be able to explain to me the differences and similarities between the applications of the philosophical thesis of disjunctivism as they apply to epistemology and to the philosophy of perception respectively?

    GPT-3.5:

    Certainly! Disjunctivism is a philosophical thesis that has been applied to both epistemology and the philosophy of perception, although there are some differences in how it is applied in each area.

    In epistemology, disjunctivism is a theory of knowledge that emphasizes the distinction between knowledge and mere belief. According to disjunctivism, knowledge is fundamentally different from belief because it involves a direct and non-inferential connection between the knower and the world. This direct connection is typically characterized in terms of a "good" or "veridical" experience, where the experience is said to provide the knower with direct access to the world.

    On the other hand, beliefs that are not based on a "good" or "veridical" experience are mere beliefs, rather than knowledge. Disjunctivists argue that there is a fundamental difference between the way that we come to know things and the way that we come to have false beliefs.

    In the philosophy of perception, disjunctivism is a theory that aims to explain how we can have perceptual knowledge despite the fact that there are many ways in which our perceptual experiences can be mistaken. According to disjunctivism, our perceptual experiences are fundamentally different from the way that things are in the world.

    This means that our perceptual experiences are not identical to the objects or properties that they appear to present to us. Rather, they are distinct from those objects or properties, and it is through this distinctness that we are able to have knowledge of the world. Disjunctivists in the philosophy of perception often argue that the only way that we can be certain that our perceptual experiences are veridical is through our ability to rule out alternative explanations for those experiences.

    In both cases, disjunctivism emphasizes the importance of distinguishing between knowledge and mere belief. However, the specific application of the thesis differs between the two areas. In epistemology, disjunctivism is primarily concerned with the nature of knowledge and the distinction between knowledge and belief. In the philosophy of perception, disjunctivism is primarily concerned with the relationship between our perceptual experiences and the objects or properties that they appear to present to us.

    Reveal

    Hi GPT-4!

    Might you be able to explain to me the differences and similarities between the applications of the philosophical thesis of disjunctivism as they apply to epistemology and to the philosophy of perception respectively?

    GPT-4:

    Hello! I'd be glad to help you understand disjunctivism and how it applies to both epistemology and the philosophy of perception. Disjunctivism is a philosophical thesis that has been influential in both areas, but its applications are different in each.

    Disjunctivism in Epistemology:

    In epistemology, disjunctivism is a position that seeks to explain how we can have knowledge of the external world by emphasizing the differences between genuine cases of knowledge and cases of deception or error. Disjunctivists argue that when we have knowledge, there is a distinct, non-reducible kind of mental state that we are in, which cannot be captured by simply describing the common features between cases of knowledge and cases of deception.

    One motivation for epistemological disjunctivism is to resist skepticism. Skeptics argue that because our perceptual experiences can be indistinguishable between cases of veridical perception (when we accurately perceive the external world) and cases of deception or illusion (such as hallucinations or dreams), we can never be certain that we have knowledge of the external world. Disjunctivists, on the other hand, maintain that there is a fundamental difference between these cases, and that we can have knowledge of the external world based on this difference.

    Disjunctivism in the Philosophy of Perception:

    In the philosophy of perception, disjunctivism is a position that concerns the nature of perceptual experiences. Disjunctivists argue that the mental states involved in veridical perception (when we accurately perceive the external world) and in hallucinations or illusions are fundamentally different in kind, even if they may be subjectively indistinguishable.

    This position stands in contrast to the common-factor theory, which holds that there is a common mental state shared by veridical perception and hallucination, usually called a 'sense datum' or 'sensory experience,' that is then either accurately or inaccurately related to the external world. Disjunctivists deny this common mental state, arguing that our perceptual experiences directly involve the external world in the case of veridical perception, whereas hallucinations involve a completely different kind of mental state.

    Similarities and Differences:

    In both epistemology and the philosophy of perception, disjunctivism is characterized by its emphasis on the differences between veridical and non-veridical cases (knowledge vs. deception in epistemology, and veridical perception vs. hallucination in the philosophy of perception). In each domain, disjunctivists challenge the idea that there is a common mental state shared by these different cases.

    However, the specific applications of disjunctivism differ between the two areas. In epistemology, disjunctivism is mainly focused on refuting skepticism and providing an account of knowledge. In the philosophy of perception, disjunctivism is concerned with the nature of perceptual experiences and how they relate to the external world.

    While these differences exist, the underlying motivation for disjunctivism in both areas is often the same: to emphasize the direct and unmediated relationship between our minds and the external world, and to challenge accounts that rely on a common mental state shared by genuine and deceptive cases.

    I don't think he would necessarily be. This book by Jacques Bouveresse looks interesting but I haven't looked into it yet (except for the blurb).

    If you don't mind me taking the lazy path, your question reminded my of some insightful comments Anders Weinstein had made in the comp.ai.philosophy Usenet newsgroup 25 years ago. I managed to find them again:

    I would be content to label myself a phenomenologist, and know
    something about Heidegger, less about Husserl. The marvelous idiom that
    worldly objects "show up for us" comes from the Heidegger translation
    of Dreyfus or Haugeland.

    I can't say I understand this. I would say it is clear that the
    cogntivist's concept of unconscious sub-personal states and operations
    should be sharply distinguished from other concepts of the unconscious
    or pre-conscious, e.g. Freud's. The latter purports to be a
    person-level phenomenon. For example, if I say that you are
    unconsciously resentful of someone, I do not mean that there is a
    representation of anger in some sub-personal computational module
    inside your body; I am rather talking about a pattern or tendency in
    your molar conduct that is not transparent to you.


    A happy middle road between operationalism (behaviorism) and Cartesianism

    No. First, operationalism is a well-known failure as an account of the
    methodology of physical science, mainly because the greatest successes
    in physical science were achieved by positing undeterdetermined theories
    (models).

    A standard Chomskyan challenge for Skinner, for example, is why he is
    insisting that psychological science ought not to avail itself of the
    same sort of methods as physical science. If physical science systematizes
    phenomena by positing unobservable entities only loosely tied to observable
    manifestations, why shouldn't cognitive scientists emulate this practice?

    But there is a more simple reason that behaviorism is not a physical
    science. It is that the concept of "behavior" at issue is not a
    physicalistically acceptable notion. The moon in its orbit is not
    behaving in this sense, and is not subject to behavioristic laws.
    Roughly only living things are said to behave in this sense.

    Of course that is not a criticism of behaviorism. It is only a criticism
    of the false claim that behaviorism is a physical science. No, it would
    be a distinct science with it's own level of description. It's fundamental
    concepts are not reducible to those of physical science, I believe.

    Moreover, the question of what descriptive vocabulary to use when
    describing "behavior" is left open. On the one hand, I believe Skinner
    and his followers are not very precise on what is allowed within their
    "data language" as "observable behavior". On the other hand, from a
    wider point of view, what they do allow depends on adopting some
    artificial restrictions to impoverish the descriptive vocabulary.

    Without such restrictions there is nothing to prevent us from
    characterizing "observable behavior" in mind-laden descriptive terms,
    and the dogma -- common to behaviorists and anti-behaviorists alike --
    that mental states of others are unobservable or only known by
    inference collapses. If I can use things like "John insulted Mary" or
    "Mary snubbed him dead" or John expressed his intention to go to
    Vienna" as descriptions of "observable behavior" -- and why should they
    not be? -- then "observable behavior" seen as manifestations of subjectivity
    may be displayed internally related to psychological states of others.

    Anyway, the key point is that I think it is a mistake to assume that
    behaviorism is "the physics of people", or that the privileging of the
    behaviorists preferred descriptive vocabulary can be justified on
    general methodological principles. It is a hope for a science at a certain
    level; and certainly it could turn out that the behaviorist's language
    is no more useful in application to human behavior than the language of
    spirits and humours and demons.

    >I wish to finish with the Buddhist word Anatta. It means "No soul either
    >within or without." May it save you from your suffering.

    I would cite "The human body is the best picture of the human soul"
    (Wittgenstein). However, making sense of this requires that you be able
    to see the doings of the body *as* expresive of subjectivity, as
    manifestations of a "soul" if you like (a person with a psychology).
    For example, you have to be able to read emotions in a face, a posture,
    a gesture. This sort of "soul" is perfectly observable if you know how
    to look.

    The idea of mind as expressed in observable behavior is a happy middle
    road between behaviorism and Cartesianism. Both of the latter rest on
    the false presupposition that mentality of others is unobservable, that
    "observable behavior" must denote behavior under a reduced description in
    which it is not expressive of mentality.
  • What is a good definition of libertarian free will?
    So, are you suggesting that there is an additional component to rational thought, a purely semantic aspect, that is enabled by, but is not itself determined by, neuronal activities, and that can feed back into the neuronal activities and change them, thus creating a situation which is not completely physically deterministic? Or something like that?Janus

    I'm not saying that our proclivity to be swayed by rational arguments, for instance, changes our neuronal processes. To take another analogy, a word processor's ability to rearrange text when the user modifies the width of a page or column isn't something that "changes" what the computer's CPU does. (The CPU maps inputs to outputs in the exact same way regardless of the program that it is running.) Rather, the manner in which the word processor (qua application) structures the functioning of the CPU+memory+peripherals ensures that this high-level function is possible. The CPU enables this but only on the condition that a well behaved (unbuggy) word processor has been loaded in memory. Our being accultured and taught language likewise are conditions under which our brains enable us to rationally deliberate and think but not the source of the cogency of our thinking.

    Indeed! Its agreeableness and tendency to endorse its user's viewpoint with little pushback no doubt are in part a consequence of its fine-tuning through reinforcement learning from human feedback (FLHF). But there also are reasons for this that directly relate to its architecture. While a response to your query is being produced, elements from its vast (tacit) knowledge base only are being mobilized to the extent that they are contextually relevant to maximizing the local coherence of the ongoing dialogue (and hence make every single new token that it produces the most "probable" one to follow the other ones). GPT-4's rationality and the cogency of its responses are emergent features of this process.

    In order that it would seek to mobilize its knowledge for providing more pointed criticisms, either some changes to its architecture would need being implemented (to allow, for instance, some virtual "inner monologue" to occur prior to the production of the completion tokens), or you'd need to have recourse to some prompt engineering methods. Some of those methods can be quite simple. You can ask it directly to mobilize its knowledge and understanding of fields X, Y and Z to offer the most cogent criticism of your position.

    That's awesome ! Any overall thoughts about Sellars and Brandom ? ( I haven't looked into McDowell yet.)plaque flag

    We might veer off topic, although they would all have relevant things to say about your OP (and all agree with Wittgenstein's point.

    I had made this comment here five years ago:

    "Oops... I now realize that I had Jay Rosenberg and Alex Rosenberg confused in my mind. Jay, who unfortunately passed away 10 years ago, was Sellars's student, not Alex.

    I had them both correctly pegged as 'scientistic foundationalists', though. I'll say more about 'left-wing' Sellarsians (Rorty, Brandom, McDowell, Williams) versus 'right-wing' Sellarsians (Millikan, Churchland, Jay Rosenberg, Dennett, and also, I thinks, Brassier!) in another post."

    Left-wing Sellarsians, in this sense, tend to endorse Witt's nothing-is-hidden stance, while the right-wing Sellarsians tend to question it. Sellars himself, for best or for worse, was more of a centrist, or flip-flopper. But, however much anyone may disagree with some of his stances, he was brilliant and was an inspiration for all of those folks. (I'm curious to see how well GPT-4 understands Sellars' Myth of Jones.)

    Reveal

    Hi JPT4!

    Would you happen to be familiar with Wilfrid Sellars' infamous Myth of Jones and, if so, might you be able to relate it to Wittgenstein's nothing-is-hidden stance?

    GPT4:

    Hello! I believe you meant to address me as GPT-4, not JPT4. Nonetheless, I'm happy to help!

    Wilfrid Sellars' "Myth of Jones" is a thought experiment presented in his paper "Empiricism and the Philosophy of Mind" (1956). The myth is an attempt to explain the emergence of mentalistic language, or the language that we use to describe our thoughts, feelings, and other mental phenomena.

    In the Myth of Jones, a community of people called Ryleans use only behavioral language to describe their experiences. They do not have any mentalistic concepts or vocabulary. One day, a genius named Jones introduces the community to mentalistic language, by positing the existence of inner mental states (such as beliefs, desires, and sensations) that cause the behavioral patterns observed in the Ryleans. Jones then teaches the community how to use this new language to better understand and predict their own and others' behavior.

    Wittgenstein's "nothing is hidden" stance comes from his later work, particularly "Philosophical Investigations" (1953). Wittgenstein argues that our ordinary, everyday language already contains everything we need to understand the nature of our mental lives. He believes that philosophical problems arise when we try to look for hidden, underlying structures or entities that explain our experiences. In other words, he opposes the idea that there is a hidden realm of mental phenomena that exists beyond the ordinary use of language.

    Relating the Myth of Jones to Wittgenstein's "nothing is hidden" stance, one could argue that Sellars' story is an attempt to show how we might come to develop mentalistic language in the first place. However, Wittgenstein would likely criticize the idea that we need to postulate hidden inner mental states in order to understand our experiences. Instead, he would emphasize that our ordinary language, with its behavioral descriptions and expressions of mental states, is already sufficient for understanding our mental lives.

    In summary, while Sellars' Myth of Jones is an attempt to explain the emergence of mentalistic language by positing hidden inner mental states, Wittgenstein's "nothing is hidden" stance would argue that our ordinary language is already sufficient for understanding our mental lives without postulating such hidden states.

    PN:

    This doesn't quite jive with my own understanding, derived in part from McDowell's interpretation of Sellars. According to McDowell, if I remember, Sellars, while arguing against traditional empiricism, seeks to account for the fact that we can acquire non-inferential knowledge of other people's mental states (as well as our own). But this precisely does not amount to positing hidden internal states. Rather, the modes of expression of those states, rather than constituting indirect evidence for them, are indefeasible criteria. This matches what Wittgenstein means by "expression". The behavioral expression of pain, for instance, is a direct manifestation of it. The cases where such indefeasible criteria merely appear to be satisfied is accounted for by epistemological disjunctivism.

    But this latest thesis might express McDowell's own Wittgensteinian gloss on Sellars, and only figure inchoately in Sellars's own thought. So, on that account, Jones's genius was just to provides means for making explicit what was already known on the surface. (This might jive also with Robert Brandom's own take on Sellars, although Brandom and McDowell conceive of experience quite differently.)

    GPT4:

    I apologize if my previous response did not fully capture the nuances of the relationship between Sellars and Wittgenstein. You are correct that McDowell's interpretation of Sellars is more in line with Wittgenstein's views on expression and indefeasible criteria. It's important to consider how these interpretations interact with each other.

    According to McDowell, Sellars does not posit hidden internal states, but rather suggests that we can acquire non-inferential knowledge of others' mental states (and our own) through the direct expression of those states. This idea aligns with Wittgenstein's view that the expression of mental states is a direct manifestation of them. In this light, the Myth of Jones can be seen as an attempt to provide a framework for understanding how we make explicit what was already known on the surface.

    Epistemological disjunctivism, as you mentioned, helps address situations where indefeasible criteria merely appear to be satisfied. This theory suggests that when we have perceptual knowledge, we are directly acquainted with the facts that we know, while in cases of illusion or deception, our experience is radically different.

    Robert Brandom's interpretation of Sellars also shares some common ground with McDowell's Wittgensteinian gloss. Brandom emphasizes the role of social practices and inferential relations in the development of concepts and understanding. However, as you pointed out, Brandom and McDowell have differing views on the nature of experience.

    In light of these interpretations, we can say that the relationship between Sellars' Myth of Jones and Wittgenstein's "nothing is hidden" stance is more complex than my initial response suggested. Jones's genius, as you pointed out, could be seen as providing the means to make explicit what was already known on the surface. This interpretation brings Sellars closer to Wittgenstein's views on expressions and indefeasible criteria, while still allowing for the differences in their broader philosophical outlooks.

  • Nothing is hidden
    But I take Wittgenstein to be saying something more like: theoretical categories as such are inapt in some cases.Jamal

    I agree, and so would, I assume, Ryle, Strawson and Austin. This is very much the whole point of ordinary language philosophy. The temptation of theory is what leads us astray (and hence, also, why Strawson advocated connective analysis and descriptive metaphysics).
  • Nothing is hidden
    As I also am inclined to do. Perhaps what I meant is, even though nothing is hidden, this is also not something that everyone can understand. Philosophy is an antidote to the lack of wisdom, but that lack is the want of something. Maybe that is lack is one of perspective but that perspective not something that we all have.Wayfarer

  • Nothing is hidden
    So as a corollary - if nothing is hidden there is nothing in need of discovery?Wayfarer

    I think a better lesson to be drawn from Wittgenstein's point is that what impedes understanding oftentimes isn't the lack of data but rather the fact that we aren't looking at the phenomenon in the right way. I say "oftentimes" because in the realm of empirical science, more data often is needed. But Wittgenstein, and also Ryle, Strawson and Austin, were insistent that, when intelligence and mindedness are at issue, what leads us to be puzzled by the phenomena is our tendency to subsume them under theoretical categories that just aren't apt at making sense of them. They weren't targeting science but rather scientism.
