    Recent developments in the West are very concerning. Robert Reich, Clinton's Secretary of Labor, just called for "reining in" Elon Musk.fishfry
    Why does that concern you? Everybody who has power has an opposition. The opposition always thinks that those with power should be "reined in" or crushed. (Actually, if you think about it, that's really a very mild comment compared with what some people say). Most people with power are either "reined in" by the opposition or their own failures. I've no idea whether Musk will be reined or crash and burn. At the moment, it's impossible to tell which it is to be. The sooner the better, as far as I'm concerned. There'll only be another like him afterwards.

    There are many other examples. You talk about Putin and Xi but you don't seem concerned about the creeping -- actually now galloping -- authoritarianism and censorship in the west. I'm very concerned; you much less so. So I don't think my point was unfair. For a Brit to ignore these issues lately I find very strange. They're putting people in jail in your country for very anodyne online comments.fishfry
    It depends what you think is anodyne. Compared to the way that some people carry on (without being thrown in jail), it probably is anodyne. But most people's comments are just hot air - unpleasant, but not harmful. Look at the consequences.
    There was a famous speech in the 60's by a Conservative politician named Enoch Powell, in which he drew everyone's attention to the flood of immigration into Britain, painted a terrible picture of the abolition of the "British way of life" and announced that there would be "rivers of blood" in the end. Was he reporting? Or was he inciting? I don't know what his motivation was, but I know what happened as a result. It wasn't rivers of blood, but it did involve bloodshed and it was very ugly.
    You may have seen the reports of the report released about the fire in Grenfell Tower. Everybody is very shocked and horrified. In a way, so am I. But I have known it was coming ever since the then Government relaxed the building regulations. It was only ever a matter of when and where. It was obvious. It was also always obvious that when it happened most people involved would say it was not their fault, even though it is obvious that they all contributed. No clean hands.
    There has never been a golden age when there was no censorship, no authoritarian squelching of opposition. It was ever so, it will always be so.
    I'm a somewhat old-fashioned middle-of-the-road liberal and I felt more comfortable 20 or 30 years ago. I grew up in the post-WW2 consensus/settlement. It was never what it seemed to be and it fell apart anyway. (If you want a date, it was the election of Margaret Thatcher in 1979 that did it.) Once that has happened to you, you never, ever buy in to anything else with the same innocent, deluded conviction.

    I'm kind of running out of steam on this site. Might need to wrap this up soon.fishfry
    If you do decide not to continue, that's fair enough. I wouldn't want to (couldn't) detain you if you have better things to do. So long as you aren't leaving for the same reason that you left the Lounge. Better to let me know when you make your decision, so's I know what's going on. If and when I make the same decision, I will let you know. OK?
  • A quote from Tarskian
    A master or slave in isolation would be like a part disconnected from the whole, and in both cases the lack of cooperation or communion will make their lives worse than what they otherwise would be.Leontiskos
    Why do you assume that a natural leader with no people to lead and a slave without a master to serve will inevitably live in isolation. Why cannot they live in society?
    Come to think of it, he divides Greek society into two groups "the many" and "the few", natural slave and natural leaders. Natural slavery is not necessarily legal slavery and vice versa, it would seem. So maybe that is what he is thinking. I'm finding this very confusing. I think this would all have been a lot clearer if we could just drop the bit about slavery and talk about leaders and followers. It is at least plausible that anyone who is not a leader is a follower. Then we could say, with a clear conscience that natural leaders with natural followers makes for a peaceful society and the people who are not natural leaders may become leaders, but they will be poor leaders, and vice versa for followers. There would still be arguments about it, but at least what is at stake would be clear and make sense.

    Yes, I agree.Leontiskos
    I'm glad about that.

    It seems to me that universal equality means that the same things are appropriate to each. Or at least it often means this, or leans in this direction. A kind of classlessness.Leontiskos
    But now I'm a bit confused. It is just obvious that there are some things that are in common between all human beings (whether by essence (definition) or by accident (empirically)) and other things that are not. So yes, everyone is equally entitled to vote and equally entitled to a fair trial.
    So perhaps I should reformulate a principle of non-discrimination, which requires that people are not discriminated either in favour or against on irrelevant grounds. Aristotle specifically picks out the case of Helen of Troy claiming that the fact that her parents were divine meant that she had special privileges. Aristotle rejects that. So it looks as if he believed in that principle. Does that help?
    I'm all for classlessness. But there's nothing wrong with distinguishing between classes of people when the criterion of membership is relevant. (People who are sick and people who are well).
  • Wittgenstein, Cognitive Relativism, and "Nested Forms of Life"
    What I mean by information here is purely about distinctions one can signal that map to distinctions in reality.Apustimelogist
    So a map of a single grain of sand cannot signal distinctions between grains, and a map of the inside of a grain cannot signal the whole grain, and a map of part of the beach cannot signal the dune at the back of the beach.

    What I am saying isn't to do with the pragmatics of navigating one's picture of the universe. It is not really about strong reductions as in the wikipedia descriptions I gave.Apustimelogist
    Well, I'm picking up what you said about large-scale and small-scale models/maps/descriptions/theories.
    Now, I don't understant what your doctrines are to do with. They are not to do with navigating the scale of them or about strong reductions. Yet you keep saying things that look like strong reductions and then denying that they are. What is what you are saying to do with? I'm at a loss to understand.

    I'm not sure whether you are saying that the analysis of water as H2O captures all the information about it.
    — Ludwig V
    I'm just saying when you make observations at finer, smaller scale, you get more information.
    Apustimelogist
    You really hate an example, don't you? Nothing but large-scale generalizations. So you miss the detail.

    In the sense of distinctions. Finer-grained observations make distinctions that do not exist for coarse-grained observations even though they may be mapping to the same sets of events.Apustimelogist
    Yes, they certainly do. But then you don't get the bigger (larger-scale) picture. Then you can't see the wood for the trees. You may know the wood is there, but that's only because you've looked at a larger scale picture. The larger-scale picture doesn't tells you about the wood, but not the trees. The smaller-scale picture tells you about the trees, but not the wood.

    Its not about information in the picture but information about the unobservable reality beyond.Apustimelogist
    You don't get information about the unobservable reality beyond the picture. It's unobservable in the picture. So it is observable, but only in a different picture.
  • Wittgenstein, Cognitive Relativism, and "Nested Forms of Life"
    Methodological reductionism: the scientific attempt to provide an explanation in terms of ever-smaller entities.Apustimelogist
    That seems to fit what you are saying pretty well.
    But I do accept that you are not claiming that because a glass of water consists of H2O, the water doesn't really exist.
    I'm not sure whether you are saying that the analysis of water as H2O captures all the information about it. But I do think you might be.

    On the other hand, it seems almost tautologically the case that if you examine reality at the finest details, you will have more information about it in the sense of being able to make distinctions - specifically in the sense of correspondence ideas about truth.Apustimelogist
    What do you mean "more information"?

    Larger scale maps have less detail than smaller scale maps, but wider scope. I wouldn't know how to answer which has more information. Ditto pictures.
    A picture of something close up which is 5" x 7" or 100,000 pixels has the same amount of information whether it is a picture of a landscape or a picture of a molecule.

    An X-ray gives us information that we cannot get without it. But it loses information that an ordinary camera does capture. A camera cannot capture smells and sounds. A microphone cannot capture the weather (or not all of the weather. Different kinds of information are relevant.

    When you think of a bishop threatening a king, your are thinking of the bishop in a wider context than if you are thinking of the bishop as an aesthetic or historic object. When you are thinking of a bishop as a physical object, you lose the context of the actual game and the aesthetic and historical context, but gain the physical properties of the bishop - down to its molecular constitution.
  • The 'Contrast Theory of Meaning' - Ernest Gellner's critique of ordinary language philosophy
    With that said, Aristotle is great once you get the hang of him.Leontiskos
    I agree. He is not easy, however. It is a mistake to think that you can read him once and get your head around. Everything is interconnected. Very little is easy to grasp from a contemporary view-point. The contrast is very instructive.
  • 0.999... = 1

    Maybe. Impatience is a big driver of the way that debates go. The media (or their readers) do not have the patience for going slowly and paying attention to detail. Everything has to be a slogan - three words - preferably monosyllables and no more than two syllables.

    My theory is that the people who might make a fist of the job are reluctant to take it one. One of the things that has changed in the last 3 or 4 decades is that the media scrutiny is much more effective and much, much noisier.
  • The 'Contrast Theory of Meaning' - Ernest Gellner's critique of ordinary language philosophy
    To clarify and or get rid of certain words or tendencies that prevent discussion from advancing.
    This applies to a lot of metaphysics and a part of epistemology.
    But as for ethics or aesthetics, I don't think ordinary language helps much, because we are dealing with facets of life which we have less depth of insight. And when there is depth of insight, what we can say about it amounts to very little:
    Manuel
    I'm inclined to agree with you.

    Why should we be just?
    Why should we not do evil?
    Why is this beautiful?
    These questions have answers which don't give much depth of insight. They tend to be rather trivial but are nonetheless crucial issues for life.
    Manuel
    Yes. I'm inclined to think that the problem is that they are too general. People do manage to have better discussions about specific issues within (and sometimes between) those categories.
  • The 'Contrast Theory of Meaning' - Ernest Gellner's critique of ordinary language philosophy
    My first example was 'we only ever see indirectly' – a claim that 'seeing' is always, with no exception, indirect. And my second example was the one you raised: 'all bachelors are unmarried'. These are both claims that admit of no exception. But to me, one of them seems like nonsense and the other one seems meaningful (in a limited way). I'm trying to work out why that is.cherryorchard
    At first, I thought that I would say that your second example is grammatical - a la Wittgenstein - and the second is not. But a second thought gives me pause. Remember, we have that argument that there is a contrast - seeing a sense-datum/experience/impression is seeing directly. So your first example becomes "Seeing an object is always, with no exception, indirect". But then experiences (etc.) are objects ("I see a red patch"), so it becomes "Seeing a physical object is always, without exception, indirect." So it looks empirical, until we realize that there is nothing that would count as seeing a physical object directly, and then it becomes grammatical. There are complications with the first that we do not find with the second. (Though I could invent some, if you want to explore an entirely trivial rabbit-hole.) The reason the first is nonsense to you is that you have a philosophical position (a grammar) and so interpret the first in a certain way. This reflects back on the contrast theory and explains why the philosophers who are accused of holding it by Gellner never articulated it.

    Seeing something in a mirror is another example – e.g., 'From where I was sitting, I couldn't see the door directly, but I could see it in the mirror.' That sounds like ordinary language to me.cherryorchard
    I'll buy that.

    ysyti'I couldn't see the airplane directly but I could see it with my binoculars' does not strike me as a familiar use of the word 'directly'. If you wanted to explain that you could only see the plane with binoculars, you might say something like: 'it wasn't visible with the naked eye'. The word 'directly' wouldn't ordinarily be used like that. But I suppose if someone was just chatting and not being mindful of how they expressed themselves, they might say 'I couldn't see it directly'.cherryorchard
    Good point.

    I suppose elucidating the specific usage suggests that 'directly' and 'indirectly' only work in contrast to one another. But it doesn't prove as much. Or does it?cherryorchard
    What it suggests is that when we look at examples carefully, we find that a yes/no answer is difficult to impossible to sustain. That is a position that Gellner does not seem to recognize.

    My point in offering the example is not to prove a point, but to help articulate what we are talking about. You suggest seeing with the naked eye - i.e. without equipment. Which makes perfect sense. Except that it hands an opening to the sense-datum theories to ask whether my eye is not the equipment by means of which I see. So it needs to be formulated more carefully. I think that dualism is the philosophical doctrine (actually assumption) behind the entire argument.

    Oops!. Perhaps the example we are looking for is the philosophical doctrine of monism. Not necessarily, provided we don't deny dualism. That's why these philosophers tend not to actually deny dualism.

    Can anyone think of any word that is meaningful without a contrast? I haven't seen an example yet.cherryorchard
    No-one seems to have come up with one yet. And yet I don't think anyone has decisively endorsed or rejected Gellner's theory.
    It does not pay to assume that a word must have an opposite, or one opposite, — Austin,
    I think that Austin has it exactly right. Notice that he does give examples - and there are plenty more - "grumpy", "uncouth". It's a question of what you do next. He doesn't jump to a theory but considers what questions to explore. Very different from Gellner.

    That is, it appears that in thinking of Wittgenstein or Austin as advocating any theory of meaning, Gellner shows he has not understood what they are up to.Banno
    Absolutely.
  • The 'Contrast Theory of Meaning' - Ernest Gellner's critique of ordinary language philosophy
    If so, then it is a sensible approach. It would be hard to believe that ethical or aesthetic considerations could be eliminated.Manuel

    I/m sorry. What's a sensible approach? What cannot ethical or aesthetic considerations be eliminated from?
  • The 'Contrast Theory of Meaning' - Ernest Gellner's critique of ordinary language philosophy
    Sometimes, universal statements about a particular term are meaningful. But why is that so?cherryorchard
    I'm sorry. I can't work out exactly what you mean. Can you give an example - or two?

    And while the word 'indirectly' does have a hypothetical antithesis ('directly'), it's very hard to see how that might apply to anything in this specific case. Someone who wasn't sure what the word 'see' meant would not be helped along if we told them 'we only ever see things indirectly'.cherryorchard
    Austin gives an example I think is helpful. But I can't remember the details, so I'll adapt it. Air traffic control radar shows a blip on the screen, with the flight number attached on a little label. The controller says "I can see flight 417", and so he does, but the visitor who peers anxiously out of the window is puzzled. The controller can see flight 417 indirectly. The visitor thinks the controller meant directly. Clearly, seeing flight 417 through the window is seeing it directly (despite the fact that it is through the window). Suppose the visitor gets out a pair of binoculars, sweeps them round a bit and says "Aha! There it is!". Does the visitor see flight 417 directly?
    The last point - the unanswerable, doubtful case is quite important to me. There's no point in pretending that this stuff is cut and dried.
    Now think about why you gave the answer you did give to each case. I think you'll find you understand how directly and indirectly could be applied in this case. I agree I don't think it would help anyone who doesn't already know what "see" means, but it does help us, in our situation, so that's all right.
    Austin does raise the question why anyone would worry about the difference in normal life - did you feel the same when you read the example? He's sort of saying that, despite the example, he's not at all sure that "direct" and "indirect" to "see".

    I'm not sure this deals conclusively with the problem, though...cherryorchard
    Neither am I. Philosophers always pretend they are sure of their answers. I don't see any harm in tagging something "not sure". Something may happen later that will help.

    Maybe it's because the sentence 'all bachelors are unmarried' is a way of defining the term 'bachelor'.cherryorchard
    Yes, that's what I meant about paying attention to the kind of statement it is - its purpose and context. That's always part of the meaning, isn't it?

    In any case, thank you for the quotation from Ryle! I will look up that book.cherryorchard
    It's good philosophy and a good read. You're welcome.
  • The 'Contrast Theory of Meaning' - Ernest Gellner's critique of ordinary language philosophy
    Right, and when I tried to bridge your thread with the thread discussing whether we see colors or only our perceptions of colors I ran into this same problemLeontiskos
    There's a quick put-down available, I think. Our perception of colours is our seeing of the colours. Your "opponent" is being misled by the common philosophical tendency to assume that every noun denotes an object.

    that is what driving a car consists of. 'Indirect' (or indeed 'direct') doesn't enter into it, unless there are two varieties of driving (real or imagined) that can actually be classified using those words.cherryorchard
    See
    One possibility is to challenge your opponent to explain what "direct" means, if not using the steering wheel and pedals. Remote control of the car would be indirect, I think.

    There are direct experiences (mental and physical sensations, feelings, thoughts) and indirect experiences of the outer world (sights, smells)cherryorchard
    This is one of those very difficult muddles that are very hard to articulate. "Indirect experiences" is a rather peculiar phrase. In the cases of sight and smell (and hearing), what is seen etc. is at a distance, but the sense-datum is experienced directly; what is experienced indirectly is the object of the experience, not the experience itself (the sense-datum). Mind you, if that is what he meant, I would say that this is another example of assuming that a noun always denotes an object. But "sense-datum" or "experience" is not an object, it is an event. A common mistake in philosophy.

    I'm interested that you call Gellner's 'paradox' argument a 'slam-dunk'. I confess I can't make sense of what he means at all.cherryorchard
    i call it a slam-dunk, because some people try to apply the format to all sorts of statements. It's formulaic and refutes without attempting to understand, which, for me, is debating, not philosophy. "We can never be certain of anything" is an example, but the reply "Are you certain of that?" suppresses the argument rather than exposing where it has gone wrong. (Mind you, in that case, the argument is sound.)

    whether we can meaningfully make such statements as 'we only ever see things indirectly' or 'we can never be certain of anything'.cherryorchard
    You have to consider that Gellner might believe one or both of those propositions. You don't. So Gellner would think that these are examples of contrast-free statements. If he did so, he would, of course, be begging the question, which is whether those claims are meaningful.

    My point about logic was not clear enough. Take any analytic statement, "All bachelors are unmarried" is a nice stock example. It is not possible for any bachelor to be married. It is contrast free. Ryle's examples below don't apply and Gellner has a case for saying that this is an example of a contrast-free statement, and, in a sense, it is. But that isn't paying attention to the kind of statement it is, and to the point that of course there are some people who are not bachelors. It's just that there are no married bachelors.

    This is interesting, thank you. I haven't read Ryle – do you remember where this idea comes up in his work? It strikes me as reminiscent of passage 345 in Wittgenstein's 'Philosophical Investigations':cherryorchard
    I agree with you about that passage.

    A country which had no coinage· would offer no scope to counterfeiters. There would be nothing for them to manufacture or pass counterfeits of. They could, if they wished, manufacture and give away decorated discs of brass or lead, which the public might be pleased to get. But these would not be false coins. There can be false coins only where there are coins made of the proper materials by the proper authorities.
    In a country where there is a coinage, false coins can be manufactured and passed; and the counterfeiting might be so efficient that an ordinary citizen, unable to tell which were false and which were genuine coins, might become suspicious of the genuineness of any particular coin that he received. But however general his suspicions might be, there remains one proposition which he cannot entertain, the proposition, namely, that it is possible that all coins are counterfeits. For there must be an answer to the question 'Counterfeits of what?' Or a judge, who has found all too many witnesses in the past inaccurate and dishonest, may be right to expect today's testimonies to break down under examination; but he cannot declare that there are no such things as accuracy and sincerity in testifying. Even to consider whether this witness has been insincere or inaccurate involves considering what would be the honest or precise thing to say. Ice could not be thin if ice could not be thick.
    — Ryle, Dilemmas, pp. 94, 95
    This would be something that Gellner might elevate to a theory. But Ryle does not present the claim that all concepts must be like this.
  • The 'Contrast Theory of Meaning' - Ernest Gellner's critique of ordinary language philosophy
    Sure - words can be problematic in philosophy. People get stuck discussing words rather than ideas all the time, so there is room for "ordinary language philosophy".Manuel

    Actually, Austin is quite modest about ordinary language philosophy, only claiming that it is an important preparation. He does not explicitly rule out the possibility that some philosophy may survive the fire and need further consideration. But he does not explore what that further consideration might consist of, so perhaps he thought it was a purely theoretical possibility.
  • The 'Contrast Theory of Meaning' - Ernest Gellner's critique of ordinary language philosophy

    That's a very good post. Gellner made a great splash with "Words and Things". I think it was rather a marmite book. You either loved it or hated it. Personally, I hated it.

    (The Contrast Theory when made explicit leads to a neat paradox; on its own grounds, a language should sometimes be usable without contrast, so that "contrast" may have a contrast.)
    That's a kind of argument that's very popular with philosophers, because it is a slam-dunk. Unfortunately, such arguments are usually mistake, because they have over-simplified the issue.

    In this case, there is a slam-dunk reply. You can obtain a contrast to any assertion by inserting "not". So the contrast to the contrast theory:-
    a term and its denial between them do not exhaust the universe, or at least a universe of discourse.

    Here, I'm following Gellner's argumentative tactic. It doesn't help much, does it?

    Actually, I'm more than a bit puzzled about his claim that ordinary language philosophers, who rejected the idea that philosophy was about theories or doctrines, had any theory of meaning, as such. I don't recall this theory from my (admittedly not exhaustive) reading of them. If this is Gellner's summary, the possibility that there is distortion here cannot be ruled out. Where is the quotation that would back his claim up?

    So where did he get the idea that ordinary language philosophers did have this theory of meaning?

    One possibility is that he is distorting something that they do say - that a given concept will always be part of a structure, or family and so not comprehensible outside that structure. So you cannot understand what "north" means unless you understand what "south" means (what often gets left out is the you also need to understand what "east" and "west" and how the other main points like "south-west" are constructed from the basic framework). Understanding the use of the word means understanding the use of it in the context of its family.

    Another possibility is that he is picking up on an argument of, I think, Ryle, that it is not possible for all coins to be fake. If there is no such thing as a real coin, there is nothing to fake and so "fake" has no meaning. As I remember it, this was intended to apply to sense-datum theory, because that theory essentially claims that my belief that everything that I see is a three-dimensional object located in space-time is an illusion. In this case, at least, "fake" or "unreal" are defined in relation to "genuine" or "real", so there is a contrast here.

    A third possibility is that he is picking up on an argument that was popular with analytic philosophers, but not necessarily with ordinary language philosophers. This is about logic. In truth-functional calculus, an analytic statement turns out to be true in all possible circumstances. This was described as not asserting anything and hence not denying anything. (Empirical, contingent statements do, of course, deny something in asserting something.) So analytic (logically true) statements were labelled "trivial". That was the basis for Logical Positivism. Traditional philosophy expected philosophically true statements to be logically true (or necessarily) true, so all traditional philosophy could be labelled trivial - unless they were false in which case they were meaningless or nonsense.

    BTW Any ordinary language philosopher worth his salt would ask "Does Gellner ever give an example of a term that does not have a contrast?". That's the basis of a good counter-argument, because just one example would refute the theory. So, does he?
  • Wittgenstein, Cognitive Relativism, and "Nested Forms of Life"
    In my view, both philosophy and the sciences describe reality.Joshs
    Well, yes, in a sense that's true. But, in that context, I thought that further explanation of what was intended would help to clarify.
    PS I meant to say that I wanted to know what Apustimelogist would say.

    It's time to be a bit more helpful, but I'm going to take a break here and post that later.Ludwig V
    Here's the promised continuation from my last post. I hope it is somewhat helpful.

    I’m not a fan of hasty generalization, or of generalization without examples. Generalization is all very well, in its place. But I’m just going to discuss three examples, with the aim of showing the variety of relationships that there are between levels of description or scales of models. One size definitely does not fit all.

    A (sandy) beach. Lots of sand accumulated along the edge of the sea or a river. One might think that nothing changes as one zooms in, until one can discern the individual grains. But it’s not as simple as that.
    Zoom in so as to cut out the sea. You have a sandbank – sand banked up over and against the underlying geology. Not much has changed, in a way, but it clearly is not a beach any more. Descriptions are often a question of wider and narrower contexts, or of focus, if you like.
    Zoom in closer. In a way, there’s no obvious level between the bank and the grains, but we can identify a heap of sand and a volume of sand as segments of a bank or beach – I call them segments because they can be cut out and removed from the bank. But the sand that we remove does not constitute a bank or a beach. So, in a sense, nothing has changed.
    Yet closer, and finally we arrive at the grains of sands, which are independently existing components in the sense that they can be individually separated from the beach or bank.
    The game changes at this point, so I’ll move on.

    A flat-pack bookcase When it arrives, it is not a bookcase, but a set of parts for a bookcase. We can lay them all out on the floor, count them, check them. Now, what needs to happen to make it a bookcase? All the parts are there. Nothing needs to be added. What’s the problem? Easy, the parts needs to be put together as designed. But the design specifies the structure of the finished article; it is not a missing element that needs to be added to the parts.
    But the bookcase has a top and bottom, a left side and right side, a front and a back. These are all parts of the bookcase. Where did they come from? They were not laid out on the bench, although the part that was to become the top was there, and it is called the top because when it is where it is supposed to be. Its top will be the top of the bookcase. Each shelf – and the part that will form the bottom - also has its own top, but the bottom of this part will also be the bottom of the bookcase. But the point here is that these parts are not components that can be separated from the bookcase and laid out on the floor or work-bench.
    Holism. Levels of description are interdependent. One cannot understand what the parts are without understanding the role they play in the whole, which conditions their physical properties like shape, size, composition, etc.
    I’ll leave out all the other dimensions (descriptive systems) that the beach is part of. Aesthetics, politics, economics. Zooming in and out won’t ever capture them. But that's not a problem - it's a feature.

    A rainbow A bookcase is special because it is a human artifact, with a purpose. A rainbow does not, it is a very different from a sandy beach. It has parts, but not separable parts. There is the shape, the bands of colour, but that’s more or less it. So is it a physical object? In a sense, yes, but it would be less misleading to describe it as a physical phenomenon.
    To understand what a rainbow is, we look to physics. To view a rainbow, your back must be to the sun as you look at an approximately 40 degree angle above the ground into a region of the atmosphere with suspended droplets of water or even a light mist. Each individual droplet of water acts as a tiny prism that both disperses the light and reflects it back to your eye. As you sight into the sky, wavelengths of light associated with a specific color arrive at your eye from the collection of droplets.
    I’m sure you know the rest of the story. But there is a very complex step about the explanation why we see a single large arc instead of multiple small ones. I've gathered that it involves fractals, so it is likely beyond me, though I would love to understand it. But it is very relevant because it is a holistic effect, not a compound of the individual reflections from the individual rain-drops.
    One might say that this is an explanation of the cause of the rainbow, but that generates a huge metaphysical issue about what the rainbow is, and a distinct temptation to say that it is not a physical object, but a mental one. Unless one wishes to embrace dualism, we need to say that the explanation in physics is an analysis of the rainbow, not a cause. (In the same way that we would say that the physics of a single grain of sand is an analysis, not a cause – thought it does of course cause the behaviour of the grain.)

    I’m not arguing that we have to abandon the large-scale, small-scale model or the idea that physics explains everything, just that we recognize there are several ways that levels of description (scale) and categories of objects map on to each other and that the domain of physics is, well, the physical. So other forms of explanation also have their non-hierachical place.
  • Wittgenstein, Cognitive Relativism, and "Nested Forms of Life"
    I mean redundant more in the informational sense wherein it just means that these descriptions are already repeating information about reality (in a correspondence theory of truth sense) that is already in the smaller scale descriptions.Apustimelogist

    Well I am just implying that her work isn't actual physics, its philosophy and what she is saying is not a description of reality with scientific consensus which is relevant because it means that introducing her into a comparison with newtoenian physics is more or less just postulation.Apustimelogist
    We all agree on that this work of hers is not physics, I think. But then, I thought that describing reality was essentially a job for physics. Philosophy might ask what reality is, but it wouldn't necessarily be particularly interested in describing it. I didn't read that part of the discussion about Newtonian science. I thought it was probably beyond my competence. I wonder if maybe you are applying the criteria for science to philosophy?
  • Wittgenstein, Cognitive Relativism, and "Nested Forms of Life"
    I've only got 10 minutes, which is a shame. So, initial comments.
    Philosopher of science Joseph Rouse is one of Barad’s biggest champions. He considers her notion of materialism to be a version of naturalism that avoids the pitfallls of other naturalistic conceptions of nature.Joshs
    I like naturalism. But I've regarded it as materialism without the ontological and conceptual dogma. So there's room in my head for something more accurate.

    I take Barad to claim instead that nature as revealed by the sciences is itself normatively constituted.
    Well, the concept of nature is obviously normatively constituted. So far it's just a beginning of an analysis. Not a criticism - just a reservation.

    First, she argues for the ontological priority of “phenomena” over objects.
    That's an ancient piece of philosophy. Here, there's some need for discussion to sort out just what phenomena are. Data?

    She then argues that phenomena in this sense must incorporate conceptual-discursive normativity. Conceptual-discursive norms are not something imposed upon phenomena “by” us, however. On the contrary, we ourselves only become agents/knowers as material components of the larger patterns of natural phenomena.
    This bothers me. Phenomenologists have this habit of saying something and taking it back. I realize that description is a bit crude. But it expresses my feeling that I'm being offered dogmatic assertion rather than argumentation. I think the idea is that what she writes should be seen as so obvious that it needs no argument. (as in both Wittgenstein and Heidegger. I'm not claiming such writing is impossible, but, for me, this isn't it. More needs to be said.

    Thus, Barad neither reduces conceptual-discursive normativity to anormative causal relations, nor imposes already-articulated conceptual norms upon the material world. Instead, she is arguing that the natural world only acquires definite boundaries, and concepts only acquire definite content, together.
    I think I can agree that the discourse of the sciences is the product of interaction with the phenomena, if that's what she's getting at. But I don't see the necessary explanation that the concept of science is like the lens through which we encounter the world. One requirement of that lens is that what we encounter and the way we encounter it must be norm-free. I've just been tangling with Aristotle's metaphysics, which is a splendid example of what I hope we have left behind. It isn't science or at least, not what we require of science.

    Once that conception is in place, Barad goes on to argue that our participation in the phenomena we understand scientifically makes ethical and political responsibility integral to conceptual-discursive normativity as well.
    Well, it could only need saying to an audience of scientists, but for normal people that's just obvious. But, I repeat, the practice and theory of science must be as norm-free as we can make it. Otherwise, there's no point.
  • Wittgenstein, Cognitive Relativism, and "Nested Forms of Life"
    I mean, clearly she is not a physicist and there is no mathematical model here. It's just speculative interpretation withiut the benefit of a formal model that demonstrates anything tangible.Apustimelogist
    Well, it is seems reasonable to recognize that she is a physicist but a physicist who is not, when she writes what is quoted, doing physics. That's allowed. What I object to is that while her perspective may be interesting and relevant and legitimate, it has no special authority just because she is writing from the perspective of a physicist. To be fair, I don't think she would claim that. But I'm encourated to believe that a mere philosopher might have something to contribute.

    but the model of causality it expresses is designed to apply equally to the micro and the macro levelJoshs
    I don't know about "designed", but certainly it is expected that it will. That expectation may be disappointed, but all too often, the existence of anything that it does not apply to, is denied.
    I don't think the "model of causality" is as much at stake as the question of whether models at one scale can give satisfying explanations of higher levels.Apustimelogist
    Well, we both think they can. Our difference is about the concept of "level". Specifically whether the assumption that all the different descriptive perspectives that are available to us dovetail neatly into a single hierarchy.
    It matters which cuts are enacted: different cuts enact different materialized becomings…. — Barad
    This is much closer to my perspective, but it neglects the complication introduced by the apparent limitation of "becomings" to "materialized". From my perspective, some varieties of becomings are introduced, not by materialization, but by interpretation. (as in puzzle pictures.)

    any kind of observation or perhaps description about the smallest scales of reality will have more information about reality than all the scales upwards simply by the fact that descriptions on higher scales necessarily coarse-grain over details, while at the same time all the observations on higher scales are effectively redundant in terms of how they would correspond to a mind-independent reality.Apustimelogist
    If that isn't reductionism, I'll eat my hat. It's the "higher scales are effectively redundant" that does it.

    Now let’s take a non-linear model of a particular sort, an account which begins from the assumption that no attributes of a physical object pre-exist its actual interactions with other objects, and that each actual interaction subtly changes the qualitative properties of the objects involved.Joshs
    My word! This is very close to Berkeley. It would be interesting to dissect the differences, but I guess you would find that irrelevant, and perhaps it is.

    Barad is fascinating. It is very close to philosophy. From the language, I reckon she has been reading phenomenology. Nothing wrong with that. But it also echoes a familiar issues from Berkeley and Ayer. First you say it:-
    In my agential realist account, scientific practices do not reveal what is already there; rather, what is ‘‘disclosed’’ is the effect of the intra-active engagements of our participation with/in and as part of the world’s differential becoming. — Barad
    ... and then you take it back:-
    Which is not to say that humans are the condition of possibility for the existence of phenomena. Phenomena do not require cognizing minds for their existence; on the contrary, ‘‘minds’’ are themselves material phenomena that emerge through specific intra-actions. Phenomena are real material beings. What is made manifest through technoscientific practices is an expression of the objective existence of particular material phenomena. — Barad
    Yes, I have been reading Austin.
    There is an unusual - to me - twist to this, however, in the phrase "material phenomena". There's a perfectly respectable use of the word in science to mean "that which needs to be explained" or, possibly "data". But the limitation of phenomena to "material phenomena" is unusual, and puzzling. I scent reductionist tendencies here.

    It's time to be a bit more helpful, but I'm going to take a break here and post that later.

  • A quote from Tarskian
    A disease is contrary to human nature. That is the point. If it were not contrary to human nature then the human will and immune system would not oppose it. It is not being said that disease is contrary to Nature in some absolute sense.Leontiskos
    I'll abandon the example of disease and this point until and unless l can work out a better way of putting it.

    Voluntary slavery is not a contradiction if we attend to Aristotle's terms. Indeed, it is not clear that voluntary slavery of any kind is an analytical contradiction.Leontiskos
    Simpson's point in the quote you provide is that it is not necessary to enslave them (nor to not-enslave them).Leontiskos
    You are right, Aristotle's slavery is not a sufficient condition of forcible enslavement. I was naive, then, to assume that all slaves are imprisoned by force and kept imprisoned by force as long as they are slaves. It should have been obvious, natural slaves are slaves whether anyone is forcing them to do things or not. (That's implicit in the discussion of the rules of war, where it is envisaged that the defeated army will be composed of a mixture of slaves and non-slaves.) Ordinary slavery, then, is a state quite different from Aristotle's slavery.
    There's another difference which I might as well bring up here.
    The condition that makes the natural slave need not be permanent
    Details are given on the same page. The natural slave might cease to be irrational. Presumably, one should release them at the point.
    So a slave is just a servant. It seems that masters of tame animals are supposed to look to their welfare, and presumably the same applies to servant-slaves.
    I left with just two questions. How do natural slaves who have no master live? How do natural rulers who have no people to rule live?

    For Aristotle a slave is a natural dependent in that they require the economia of a master to flourish.Leontiskos
    Does the master not require the slave to flourish? Mutual dependency, common good. Positively inspiring!
    The difference is that Henry Ford is capable of performing the manual laborer's jobLeontiskos
    Perhaps. He may well not be. He probably doesn't have the time, what with running the whole show.
    This maps to a proficiency with the mind vs. a proficiency with the body,Leontiskos
    Yes. Intellectuals do tend to down-grade physical work. They might have more respect for it if they did some for a week or two.

    I understand that some people think that Aristotle's argument demonstrates that universal human equality is nonsense. It is indeed nonsense if it means that everyone is the same. But Aristotle's argument demonstrates what it does mean. For the motivating assumption of the argument is that everyone should be treated in the way that is appropriate to them. Irrelevant circumstances (such as Hecuba's birth - Simpson p. 12) should not come into play. The only issue is what is appropriate to who. That's what universal equality means.

    It was always obvious that dealing with climate change would be a mess, and that it might well be ineffective. We can probably organize some response after the event. There will be some mitigation, but nothing less that world-wide panic will trigger serious attempts at mitigation and that won't happen until serious climate change has kicked in. As usual, the poorer countries will suffer most, and much of their population will leave, looking for somewhere safer to live. There'll be a lot of trouble.

But hey! no-one listens to doubts and compromises any more.

    Thank you very much for this. I hope you won't mind if someone who is neither mathematician or logician makes some ignorant comments - purely in a spirit of enquiry.

    "This is not provable."
    Assuming that this sentence is decidable, it is true or false.
    If it is true, then it is (true and unprovable).
    If it is false, then it is (false and provable).
    Hence, the sentence is (true and unprovable) or (false and provable). Therefore, it is a legitimate existence witness for his theorem.
    Tarskian
    This is not contorted. It's perfectly straightforward. Self-reference. I've long held the heretical view that the "witness" is not decidable. Is there any reason to suppose it must be? Of course, you could assign a third truth value to undecidable sentences, but I suppose that would be cheating.

    A better example, Goodstein's theorem, was later discovered for which the theorem itself can be expressed in Peano arithmetic but the proof cannot, making it (true and unprovable) in that context.Tarskian
    Yes. I thought that something along these lines would probably work. However, you seem to be assuming that if a theorem can be expressed, it must be true. In which case, if that assumption is correct, it is provable. Or is that idea just an assumption or an axiom or something?

    Godelian sentences are fiendishly difficult to detect in arithmetical reality because in that context we systematically use soundness to discover truth: the sentence at hand is true because it is provable. Arithmetical vision requires calculation. It is virtually impossible to detect an arithmetical fact without calculation.Tarskian
    Yes. That's what puzzled me.

    On the other hand, if we had a copy of the theory of the physical universe, observing physical Godelian facts would be trivially easy.
    Unlike in arithmetical reality, in physical reality we do not need to know why exactly a physical fact occurs in order to be able to observe it.
    Tarskian
    But not knowing why my observation is true is not the same as its being unprovable. Surely that will only work if what I observe is incapable of being proved, as opposed to my not knowing how to prove it. If I knew that it was unprovable, I think I would either not believe my eyes or at least suspend judgement.

    Our eyes do not have to calculate a fact in order to see it. Our eyes just see it. We are perfectly able to see things with our eyes that we do not understand or cannot possibly predict (up to a point, of course).Tarskian
    Well, maybe. I think most people believe that my brain does the calculations. I can see where the ball is going to land and catch it, without consciously doing any calculations or being aware of any calculation going on in my head. It's a tricky philosophical issue.
    In any case, wouldn't calculations after the event prove that I did see what I saw?

    (By the way, this is a simplification because our eyes may also use "calculations" in order to "see".)Tarskian
    I'm sorry I don't understand that. Do you mean that my eyes may follow heuristic principles, rather than calculations? Quite likely. But then my seeing would be an educated guess, which could be proved right (or wrong) after the event.
  • A quote from Tarskian
    Right, "Aristotle says that Greeks are fit to rule," does not mean that Aristotle says that every Greek is fit to rule.Leontiskos
    Well, I think it is ambiguous and I didn't recognize that. However, because he says the "the many" are not fit to rule and therefore implies that some, but not all, are fit to rule, I should have realized that your interpretation is correct. So you are right.

    I'm in a bit of a quandary here. There are two conclusions in this argument. One is about leaders. I don't have any violent objection to that argument. I think it's false, but I'm not sure that I can be bothered to refute it. In practice, it wouldn't make any difference. The other is about slaves, and I cannot accept that it is right, or even all right, to enslave any human being. So I need to show that that conclusion does not follow from the argument. Briefly.

    A. If we can identify characteristics that make someone fit to rule, then it follows that people who do not possess those characteristics are not fit to rule; it does not follow that they are slaves, or fit to be slaves. We could, instead, characterize them as natural followers or maybe natural independents (compare Simpson on tame and wild animals p.4)

    B. You may be mistaken, however, to think that "the rational are more fit rulers than the irrational" is empirical. I may be wrong, but I think that, for Aristotle at least, reason is the faculty that enables us to get things right. A leader needs to decide the best thing to do and how to do it; so, by definition leaders need to be rational.

    C.
    All he (sc. Aristotle) says is that it is unjust to enslave those who are not natural slaves. — Simpson - p.13
    So who is a natural slave and what is the index of being one?
    1 Aristotle thinks the index is irrationality. Is there anyone whose life does not include some irrationality? And some rationality? This is not a clear criterion.
    2 If slavery comes naturally to some people, why is it necessary to enslave them? One doesn't have to force a natural musician to play or a natural leader to lead. One only needs to enforce something that is against nature - irrational. A natural slave would accept slavery when it was offered. Voluntary slavery is a contradiction in terms.

    D.
    A thing is manifestly contrary to nature when it is not as its nature requires it to be, but is losing or has lost that nature. Disease is contrary to nature, in that sense. — Simpson - p.4
    That's a most confusing sense of "nature". In the real world, disease is entirely natural. That's why we take many artificial measures to restore us to health.
    We are in two minds about nature. Sometimes we consider that what is natural is good. Sometimes we consider that it is bad. It depends on the case. No general evaluation can stand up to the facts.

    Perhaps my problem is a verbal one. "Components" suggests that they are parts of the building in the sense that the roof and the windows are parts of the building. But they aren't. I would much prefer "aspects" of the building, or of the architecture, whichever you prefer.

    Their own components result in practical, beautiful, and sustainable parts of a building, but the building won't be successful as a building by merely having such parts.
    These, in turn, must be composed (e.g. balanced or distributed) in ways that make the building successful as a building.
    jkop
    Yes, you could have parts of the building that meet those critieria. But the basic point, I think, is that they are holistic. If we say that the frontage of the building is beautiful, that's a description of the whole frontage not of any part or segment of it. If we say that the building is very practical, we mean that the building as a whole is practical.

    Short version - holistic aspects of the building.

    Neural information encodesapokrisis
    That's like saying that a phone encodes the information passing down it. (Let's assume an old-fashioned phone that is connected by a wire without computers interfering). Then I can say that what is passing down the wire is the causal consequence of the sounds at the end of the line and the "decoding" is a reversion to the sounds at the other end. In a sense, it is just like a fancy megaphone. So what you are doing is treating what is passing down the wire as information. I can see nothing wrong with that, except it's a stretched sense of "code" - probably the result of the misleading analogy with information processing machines.
    I do get the point, though, at least I think I do. Biology is not reducible to physics because a living body, though it is a physical object, cannot be explained without reference to concepts that have no place in physics. They cannot be understood without taking a holistic view of the organism and what helps to keep it alive - a concept that physics has no room for.

    And yet you defend your brain tirelessly. So it must be important to you even if it is not big.

    Yes, I get that and I have never excluded those things, after all that is the level at which we engage with the world in everyday life. But I think a distinction can be made between: the use of different explanatory frameworks and ways we engage with the world that are perspective-dependent for various reasons; and then the concept of ontological grounding in principle - that behaviors described at one scale will be grounded in those on smaller scales, even if I require different explanatory frameworks to make sense of the world in any pragmatic way.Apustimelogist
    So the concept of ontological grounding is not perspective-dependent? H'm.

    Well then the only criteria I see for the plus task is that it is performed correctly in the way regular people deem it correct. A calculator can plus correctly imo.Apustimelogist
    Oh, I agree with you. Some people wouldn't. But I have to note an important difference. The calculator neither knows not cares whether it is correct. It cannot evaluate its own answer, in the sense of trying to correct wrong answers.

    You may not want to say a brain is doing what you are doing but lets see what happens when we stop the brain doing what its doing and knockout that occipital lobe - how that affects what you are doing.Apustimelogist
    Try stopping your heart or draining your blood. Same result.

    Let me try again. Consider what philosophers have said:-
    1 Everything is physics
    2 Everything is language
    3 Everything is experienced
    All true. They are all perspectives and there can be more than one perspective on anything. Physics, from my perspective, is not unique in any respect.

    In this sense, they are both emergent properties and components of the architecture.jkop
    I don't understand why you include components when I thought you were saying (correctly) that utility, beauty and sustainability are the result of other components, but not one of them. I think this may be a category issue.

    The special sciences won't answer how they causally emerge, nor how a balanced or distributed composition satisfies the success of a building. Yet every effect has a cause, and for millennia we have known that buildings should be practical, beautiful, and sustainable.jkop
    "Every effect has a cause" may be true, in a way. But it does not follow that every effect must have a cause which is a specific component of the building. The cause of utility might be an effect of the totality of the building as built, rather than as a collection of components.

    QM tells us the observer perturbs what s/he observes.ucarr
    Isn't that old news in a new bottle? Only physicists needed QM to tell them about the specificity of observation and its distortion in the process of communication.

    Well, as I've been saying, no one reads a given text exactly as another reads it. This because each individual perturbs what s/he observes individually.ucarr
    You are looking at only one side of the coin. We learn to read from each other (and we learn the language that we read and communicate in) and we learn all the skills of knowledge. Sharing and correcting
    .
    I suppose it means that in a given time period for a foundational theory, no one can discover a form more basic.ucarr
    So "simple" means "more basic"?
  • The Sciences Vs The Humanities
    Okay. Proceeding from the observer as an always local person, if we bind the thinking of an always local person to that always local person, then it too, is always local, and the abstraction of abstract thinking starts dissolving.ucarr
    I don't know what you mean by "bind". If a local person indulges in abstract thinking, and shares that thinking with other local and non-local thinkers, how does the abstraction of abstract thinking dissolve?
    (Don't forget that is the abstract dissolves, so does the concrete.)
    I have no problem with the idea that mathematical objects are real or that we can generalize from the particular to the general.

    The simple binary of concrete/abstract hasn’t dissolved away to nothing, but it has become faint.ucarr
    I didn't understand a lot of the intervening ideas. But this inclines me to retort that perhaps it needs to become faint. Binary oppositions are almost always less clear and definitie than some people would like to think.

    Might it be an ability to see how cognitive objects such as language, and cognition itself, per Gödel, will generate valid statements unprovable with the boundaries of supposedly axiomatic systems?ucarr
    I have a lot of difficulty with the idea of something true but unprovable. How could we know that such things exist, and if we do, how do know what they are? But this is a bit more specific and so it helps. I still haven't seen an example of such a truth and would love to do so.

    There may not be any elegant simplicity axiomatic to everything.ucarr
    Perhaps there isn't. But isn't that just a methodological principle that applies when there are competing theories in play? In any case, it only requires us to choose the simplest of available theories, so it would be hard to refute. By the way, what is the criterion for simplicity? Kolgorov complexity?

    Which is all very interesting and important. I mean that.

    However, it occurred to me that, as a definition, "Statements about statements" captures far too much, but we've been over that. More important is this - Berkeley's Dialogues for example can be read as a philosophical text, but also as a historical or religious text. The difference is not in the text, but in the approach to the text. Philosophy is not simply matter of texts, but of an activity, a skill, a language game, or several language games. The disciplines are different ways of reading (in the large sense) and responding to them.

    PS One can also read Berkeley as an exercise in rhetoric. The text is riddled with it.

    the public is not happy when the only people going to prison are the ones calling attention to it.fishfry
    Some of the public are quite likely not happy. Others are more bothered by the rioting and are perfectly happy. Starmer has read the mood perfectly.

    So everyone uses the example incorrectly.fishfry
    Yes. I won't use it again. And I'm all ready to slap down anyone who tries to.

    Yes right. Just don't let Two-teir Keir hear you say that :-)fishfry
    I don't think he cares much what I think, and anyway, I don't think he's listening. But you never know. Everything leaks in the end. But I do choose carefully about who I raise it with.

    And again -- in the US, the ruling class cheered on the Floyd riots and threw the J6'ers in solitary. So it's two-tier policing again.fishfry
    I can see your point. The problem is that whether you cheer on the rioters depends on whether you agree with them. You and I don't have to be impartial, so that's ok. Law enforcement does. But it's nigh on impossible, but I think most of them do try.
    I do think it is hilarious to hear Trump bleating on about how all the prosecutions against him are political. I don't know whether or how much they are influenced by political considerations. The thing is, he wants to make all prosecutions political, by appointing people who agree with him politically to, for example, the Supreme Court and throughout the legal system. What matters is whether he is guilty or not - the fair trial. He does the same thing about elections. If he likes the result, he accepts it. If he doesn't he decides that the ballot was rigged. His losing the election is not evidence that the ballot was rigged. He's not the only one, but he's the most prominent one.

    You know I like immigrants. If the government would impose some order on the system, it wouldn't be creating a right wing backlash. I don't like racist hooligans. But we have to try to grapple with the government policies that they are reacting too.fishfry
    I agree with all of that. The liberals focus too much on the individuals and the hard-liners too much on the numbers. There's a real need to balance and consensus.

    Right. But it's tricky. Nobody, not even freedom-loving and rule-resenting me, thinks online platforms should be allowed to carry criminal material.
    You know the reason I'm a little triggered by you saying I resent rules is because it's true. I've always been this way, always a rebel against authority.
    fishfry
    Where would we be without rebels against authority? But choose your issues.

    I'm on Quora a lot arguing about the JFK assassination, and people just get vile about the most trivial differences of opinion.fishfry
    You do like the contentious topics. Yes, some people are very trigger-happy. I find "Let's agree to disagree" followed by ignoring them works quite well.
    I've seen a bit of Quora (and Reddit). They look a bit too much like snake-pits for me.

    And sometimes I do the same thing.fishfry
    Don't we all? But sometimes there is a deeper issue - the arrogance of the opinion or its wilful blindness, for example, rather than its content.

    I'm trying to be nicer and more civil online. Been at it for about 24 hours now :-)fishfry
    The first day is the hardest. The hard thing is to disagree nicely - especially with sensitive people. But if you can, you might actually persuade the other side to move a bit.
  • Wittgenstein, Cognitive Relativism, and "Nested Forms of Life"
    Sure, you could argue that the objects in math are not reducible to objects in physics... they are more general and perhaps abstract than physics... but we can make any sets of arbitrary tools we want that are not inherently related or reducible in a hard way to other tools or descriptions. They are, after all, just constructs.Apustimelogist
    So are you saying that mathematical objects don't really exist? What is your criterion for existence? Is it, by any chance, being physical?
    I don't think Quine's slogan "to be is to be the value of a variable" is perfect. But it's not bad as a slogan.

    We can acknowledge the conceptual divides between different perspectives but I think we also must acknowledge that if different perspectives map up to each other substantially, like the brain and mind, then its simply seems impossible to me to not talk about those mappings in terms of some kind of underlying commonality.Apustimelogist
    I don't have any problem with the mirrored patterns of brain waves or with mapping the hormones circulating in my bloodstream with various emotions. But notice that in the latter case, the hormones do not map one to one with my emotions.
    I do have a problem with saying A's brain is in love with B's brain. I simply don't understand why anyone would want to say that - except to wind up people like me.

    I really have no idea because I don't think anyone knows exactly how they count or do plus tasks.Apustimelogist
    Nonsense. They know perfectly well how to count. Maybe they can't explain how they count very well, but that's a different know-how. So we say they act blindly. But the point is that they act correctly.

    But is what a person does independent of what a brain does? No.Apustimelogist
    I never said it was. All I'm saying is that what I do is not what my brain does - except by synecdoche.

    Given that, we can always in principle describe the brain behavior in terms of those more fundamental levels.Apustimelogist
    Quite so. But it doesn't follow that we can in principle describe my behaviour in terms of the same levels. You can describe my running in physical terms. But physics has no equivalent to an intention or to the rules of athletics, so you can't describe my running and winning a race in terms that physics would recognize.
  • A quote from Tarskian
    Though, at the same time, we can't do without this narrative aspect -- it's the sweeping, big narratives that I'm skeptical of here; so in some sense to concede that Greek Culture was given a Mediterranean empire for free because their culture was absorbed and spread across the Mediterranean after being dominated is to say, sure, we can put the story this way,Moliere
    It might help your perspective on this to point out that the Greeks thought of themselves as Athenians or Spartans or Thebans. During the Persian Wars the opposition was never more than an alliance of city states, and some cities (Thebes) simply surrendered to them. That disunity continued until Philip of Macedon defeated them in battle and force a unification treaty on them. The story after than is very complicated, but a lasting unity was finally imposed by Rome in 30 BC. So although the culture was Greek, it was not the product of any single Greek political entity.

    I do think things change, actually -- it's just not a sweeping Progressive narrative, per se. And they can change for the better. The only way I know of in which this happens is when regular people get together to demand change, though. It takes effort and planning, but it can be done.Moliere
    Some things are better, that's true. It's just that so many important things are not.

    Anarchists believe in individual needs and individuals, but that they are a part of a wider community -- rather than a bundle of self-interested individuals anarchists build collectives of cooperation which are intentionally built through collective decision-making and consensus building.Moliere
    Yes. That would be better. And I guess it can work, but only at a relatively small scale. Roughly, up to the size of community that can function at a person-to-person level.
  • The Sciences Vs The Humanities
    I, in principle, could explain in an enormous amount of detail, why these specific components, interconnected with each other in this specific way, results in the emergent property of the design.wonderer1
    I'm sure you could. Thank you for letting me off the detail. I agree that the "emergent" physical property of the gate "emerges" from the design. But the design emerges from the designer. Physics cannot even recognize a design, much less apply its laws to it.

    So it seems reasonable to me, to see understanding of emergence as something particular experts have,wonderer1
    Yes. I like the idea that it is about particular cases, rather than some very general abstraction. Generality is there the hand-waving comes in.

    If self-reference(s) is the antecedent to "they," then I might start thinking of you as being a radical QM materialist, as I am. For what I've seen so far (not exhaustive), scientists and logicians still maintain a white knuckle grip on the Principle of Non-Contradiction. Here at TPF, many debaters think they've scored a slam dunk whenever they discover a contradiction from the opposition.ucarr
    The Principle exists, but only rarely applies. You have to define your language very carefully to produce one. A fundamental rule of language appears to be to design itself to avoid the possibility f being faced by one, allowing third possibilities and shades of grey. A binary choice is almost always artificial.
    A contradiction can only do harm when it has not been spotted. The self-reference paradoxes are completely transparent and consequently do no harm (so far as I can see) - except to the poor souls who think they have to "solve" it.
    Compare the awkwardness about If P then Q when P is false. This is well understood. People have reacted in various ways. When it is not spotted it could do harm, but I don't see any need to get excited about it. (My solution is that truth values do not apply in this kind of case - and that is not a third truth value.
    I'm not sure how serious I am here, so I reserve the right to contradict myself if you reply!

    It dovetails with Gödel and, with a marvelous concision, translates his premise into verbal language.ucarr
    I didn't appreciate that. I got too annoyed at the revelation that he didn't want a definition. He wanted an algorithm that would enable an AI to distinguish philosophical texts from the rest. What would be the criterion of success? THAT would be the definition.
    Not that definitions are all that important. Geach, long ago, wrote a wonderful article excoriating the Euthyphro because Socrates equated not knowing what piety is with being unable to define it. He was quite right.

    The methodology for the scientific method might not be scientific, but it is philosophical.ucarr
    I hoped you would say that. So science, in the end, is grounded in human beings. Worse than that, not in a scientific, but history and philosophy. Oh dear!

    The observer cannot be abstracted from the experiment.ucarr
    Yes. But the observer, in my book, is not an abstraction - a point of view. (At most, a point of view is a location for a possible observer.) An observer is a person.
