I may not have been as clear as I might have been last night, though, so let me try to state this clearly now. First, to remind ourselves, I had said... "We can first of all say that one cannot know what one does not believe" to which you objected "Sure you can: I know smokings bad but I don't believe it'll affect me." Now, what I'm saying is, you cannot know something without believing it. That is, you cannot know something without believing the very same thing. Or put another way, "You cannot know X without believing X", where X stands for a particular statement, proposition, hypothesis or whatever. The same one. However, your proposed counterexample takes the form "I know X but I don't believe Y" Therefore it doesn't have the right form to constitute a counterexample. Hi Eise. Glad to see you back and hope you'll be joining the fun and frolics. A few fast shots in return... 7 hours ago, Eise said: But I could not let this pass: Dennett is definitely not a behaviourist. It seems to me you have never read something from him. Maybe just about him. I could not find an online version of it, but maybe you can find it: "Skinner skinned", from Dennett's book "Brainstorms". I know Dennett's work pretty well, Eise, but not much of a fan of his philosophy. He's certainly an engaging writer, though. I have two of his books propping up my computer screen as we speak as a mark of "respect" haha! (and a Sam Harris book as a soggy beermat). Now, I'm not sure whether Dennett ever describes himself as a behaviorist, but the behaviorist leanings are replete and unmistakable in his philosophy, not surprising given his tutelage under Quine. Presumably you're familiar with his work on consciousness and the mind in general. Dennett is one of those strange people who subscribes to (a form of) "eliminativism", i.e. the mind and all her furnishings -- beliefs, desires, hopes, fears, even consciousness itself -- do not exist, at least as commonly understood. A belief, for example, for Dennett is not psychologically real. You won't find beliefs in the brain. The only reality that he imputes to beliefs (and all the rest) is patterns of behavior. Our ascription of beliefs, on his account, are real only insofar as they allow us to predict and explain behavior; a task which would be practically impossible using physics. This is what he calls "the intentional stance". The patterns (i.e. patterns of behavior) are real; the beliefs qua mental states realized in the brain are not. 7 hours ago, Eise said: [Ignore this. Damn quote function!!!!]- RP Dennett's book "Consciousness Explained" might have been more aptly entitled "Consciousness Explained Away". And as John Searle likes to scoff, whenever you meet one of these guys who deny consciousness, you just want to go up and pinch them. I suspect he means "punch" rather then "pinch" but that would be rude. Consider this, for example, that I just googled: Quote Behaviourism flourished in the first half of the twentieth century. Philosophers from that period with behaviourist leanings include Carnap, Hempel, Russell, WITTGENSTEIN, and RYLE. Arranging some contemporary philosophers on a spectrum from the most behaviouristically inclined to the least finds QUINE at the behaviourist end, and SEARLE at the other. DAVIDSON, DENNETT and DUMMETT are closer to Quine than Searle, with FODOR, DRETSKE (and many others) closer to Searle than Quine. Armstrong and LEWIS are squarely in the middle. http://web.mit.edu/abyrne/www/behaviourism.html 7 hours ago, Eise said: I can imagine that it is difficult to see where Reg stands: maybe it helps to see that Reg is not attacking science in itself, but more the accounts many people have of understanding what science can accomplish, and how it accomplishes it. It is about what knowledge means, what truth is, what facts and theories are, etc. Quite so. A lot of scientists and science fans are simply unfamiliar with the philosophy of science, hostile even. What they don't realize is that, by and large, the majority of philosophers of science are unequivocally pro-science; they're just trying to enhance understanding as you rightly note. This is a bitter pill for many to swallow: "Who understands science better than scientists themselves, asshole!!!???" To which I'd reply, we'd be foolish indeed not to listen to what the scientists have to say. But just because Ronaldo, say, is the greatest footballer in the world, if it's an accurate account of the history and philosophy and football you want, including North Korean strikers of the 1930s and the influence of the Internet on Greek premier league soccer, Ronaldo may not be the best man to consult. Personally I find it a delight to read the popular works of philosophically versed scientists such as Gould and Lewontin, say. Extremely clever, sophisticated men. On the other hand, though, those most clueless of and hostile to philosophy -- Krauss and Dawkins (aaarrrggghhh!!!) -- are almost painful to have to listen to as they advance one screaming absurdity after another. 4 hours ago, beecee said: Arrggghh. I did it again. Hit the wrong key. Ignore this. Dunno how to remove it. 7 hours ago, Eise said: It is notoriously difficult to give an account of the relation between language and reality (and what latter exactly is...). As science must use language (even if it is 'just' mathematics), the difficulties in this respect work through all the way to science. It might even be impossible to give a consistent account of the relation between language and reality. (Because such an account must be given in language...?) Wise words, my good man. Perhaps we can lock horns together sometime in a thread on the philosophy of language sometime. One of my passions. You're Dutch, right? Bring Grolsch. I'll bring bad breath. Haha!

Reg Prescott Posted November 2, 2018 Author Posted November 2, 2018 (edited) @ Studiot First let me see if I understand you exactly, then proceed. We'll assume here, for the sake of argument, that your senses are infallible -- no Matrix, no hallucinations, no Cartesian demon, no evil scientist probing your cortex. What you call "pure knowledge", then, is that which is directly perceived. (Your pure knowledge is also, of course, belief inasmuch as it is true and justified.) If you think you see an object buzzing around the daffodils, then there is an object buzzing around the daffodils. Right? We're further assuming that there exists a taxonomy (of which you are originally unaware in the tale below) which distinguishes moths from butterflies (to quote yourself: "specialists distinguish for reasons unknown"). They are two different kinds of insects. Whether this taxonomy actually carves nature at her joints needn't concern us. All that matters is that there is such a taxonomy. Right? May I now spin a yarn to see if it captures the distinctions you want to make? Shout if I get derailed. Studiot spent the first 20 years of his life locked in a dungeon. He has the concept INSECT and uses the word "insect" competently. He's even had a few creepie-crawlie visitors in his dungeon from time to time: flies, ants, Madagascar hissing cockroaches, maybe even a tapeworm in his gruel for good measure, whatever. Studiot, however, has never seen a moth or a butterfly. Studiot has never even heard the words "butterfly" and "moth". Upon his release, Studiot understandably spends a lot of time in the park, reveling in his emancipation. To his delight he discovers a new kind of pretty flying insect he hadn't known existed: some are blue, others are green. He names this new insect kind "broth". Some broths are blue and others are green; they are all broths to him nevertheless. (Studiot, your own choice of names -- Red Admiral Butterfly and Hawk Moth -- I fear will lead to confusion. Your names presuppose, or might be taken to presuppose, knowledge of moths and butterflies, but you've never heard the words before, right?) Is this conceptually right so far? Now, one day Studiot has a chat with another stroller in the park, and excitedly tells his new friend of his discovery. He even points out blue broths and green broths flying above them. The new friend explains: "Ah, you're wrong. They do indeed look similar, but these are not two varieties of the same insect kind. They are two different kinds of insect. One is a moth; the other is a butterfly". "How can I tell which is which?" Studiot implores, with no reason to believe his companion is making this up. "The green ones are... aaaarrggghhhh!!!!", upon which Studiot's new friend succumbs to a massive coronary and drops dead. Right so far? So, by hypothesis, you know (and believe) there are such things that you call broths. Their existence is not in doubt. You've been told, though, that what you call a green broth and a blue broth, and take to be varieties of the same kind, are actually different kinds of insects. One is a moth, the other a butterfly; you don't know which is which. Now, the existence of broths is what you refer to as "pure knowledge", since it was directly perceived. That there is a distinction in kind (not just color or variety) between green broths and blue broths is what you refer to as "pure belief". I assume you call it pure belief because your information is "second hand" so to speak. That there exists a distinction in kind between the two critters, whatever we call them, is something you're taking someone else's word for. The distinction between the two sources of your information, then, seems quite legitimate. We might describe it as sensation vs testimony, or first hand info vs secondhand info, or direct vs indirect learning. What I don't think can be upheld is the distinction you're making, I think, between the former being knowledge ("pure knowledge" in your own terminology) and the latter being mere belief ("pure belief"). The former is knowledge, by hypothesis. But why can't the latter be knowledge, too? Wouldn't this depend on the reliability of your tragically deceased new buddy? Supposing your now decomposing pal was the world's leading authority on lepidoptera. His testimony on these matters would be as reliable as one could hope for. Thus, you would not only have a belief that moths are distinct in kind from butterflies, your belief would be justified, moreover true. And that sounds an awful lot like knowledge to me. Have I gone wrong anywhere, Studiot? Looking forward to your reply. Oh, finally, you asked: Quote I also underlined a question, in my quote, you have yet to answer which was that you linked three notions in your original thesis but omitted 'belief', leaving the introduction of that notion till later. Surely there can be no hidden agenda in my asking why? No reason of any significance at all. We could rename the thread "Science, Knowledge, Belief, and Truth" if you like. Will it improve ratings?

Quote and perhaps help to ameliorate some very deep confusions that have been brought to my attention through discussion with fellow members. I have certainly seen confusion, and mostly based on invalid scientific claims from yourself actually. Quote I've noticed that, in contexts related to science, some members are extremely reluctant to make any mention of the word "truth" (and its cognates: true, truly, etc.), a tendency that struck me as quite inexplicable until the reason, I think, for this misguided reticence was exposed in a very revealing comment recently. I have found that most people I have come across that see the need to discuss truth, will inevitable have some form of ID agenda. Quote If I may paraphrase: "The making of claims to truth would compromise the open-minded character of the scientific enterprise and render it more like a religion." The scientific discipline has as its foundations the scientific methodology. That essentially means that this truth is not the goal of science. Quote Knowledge, as traditionally defined since antiquity, is justified true belief. Certain inadequacies in this definition (Gettier type counterexamples) have been brought to light in recent decades, though they needn't concern us here. The above definition will be assumed in all that follows. To have knowledge of a certain proposition, to know that proposition, then, requires three conditions to be satisfied: https://en.wikipedia.org/wiki/Knowledge Quote (1) One must believe the proposition (2) One must have sufficient justification for believing that proposition (3) The proposition must be true Not really......One accepts a proposition/theeory based on observational and experimental evidence that supports it. The truth is nether here nor there. Quote Now, since truth is one of these necessary conditions for knowledge, any untrue claim -- scientific or otherwise -- cannot constitute knowledge. Without truth there can be no knowledge. Rubbish. The beauty of the scientific method is that it can be modified, changed, added to, or invalidated as new observations are obtained. This simple basic premise is something you keep ignoring in your many threads. Quote Therefore, those who deny that science -- at least in some cases -- yields truth (i.e., true propositions, statements, laws, theories, hypotheses, etc.) must also deny that science produces knowledge. But no one has ever said that that I am aware of.....This hairy fairy truth is not the object...If it happens to be hit upon accidentley, all well and good. But you seem to have come around to scientific thinking as dictated by the scientific method [the bit I highlighted] Why could'nt you just openly admit that? Quote How much knowledge has science produced about the cosmos, the stars, the galaxies, the planets?How much knowledge has science produced about evolution?How much knowledge has science produced about atoms and molecules?How much knowledge has science produced about anatomy, the brain, medicine? Quote ... the denier of truth, on pain of inconsistency, must answer: "Zilch! Zero! Nada! Not a jot! Absolutely none!". That is simply rubbish once again......This once again highlights the facts of how you twist, misinterpret, place your own meanings on words, and indulge in obtuseness when confronted with evidence to the contrary. And then you scream victim when someone alludes to the probability that you have an agenda? Quote As a footnote, one occasionally hears on these forums clandestine whispers of "absolute truth" or "universal truth". I personally haven't a clue what is being alluded to. The terms mean nothing to me. For the student of language, "true" and "false", are rather mundane predicates that apply to assertive sentences, from the most pedestrian ("My haemorrhoids are playing up again") to the sublime ("Jesus is the only begotten son of God"). Both sentences make assertions, and thus both are -- at least in principle -- truth evaluable. Now, who's afraid of the big bad truth? Evolution is as close to being fact as we can hope...We have tremendous amount of knowledge re astronomy, cosmology etc, aided by modern technological advancements, as well as the particle zoo. In fact at least in my opinion, what makes our knowledge so great is how the principal theories covering these disciplines, the BB, SR/GR and our particle zoo, seem to all fit snugly together like a jig saw puzzle. But of course that does not mean more knowledge is not to be found...We still have only seen the tip of the iceberg...DE, DM, are two areas that we have barely any knowledge of at this time. So my question to you is why are you so afraid of knowledge and science in general? Edited November 2, 2018 by beecee 1

If you think you see an object buzzing around the daffodils, then there is an object buzzing around the daffodils. Right? Please don't do this. It is most definitely and emphatically not what I proposed. It is also what I respectfully submit is what upsets many other responders here. It is also the reason I mentioned the 'level of know' and specifically excluded the interaction between thought processes and sensory perception. This is all a great shame as your following story piece is so much better thought out (not quite what I meant but sure we can talk about that). I won't quote it all since its quite long. Unfortunately your great mission to simplify has lead you to completely miss the difference in 'know' that I am trying to highlight. I apologise if my words are not up to this, but you are the self proclaimed Philosopher so should be better equipped than I am to tease the intended meaning from utterences. The point is that, by corroboration from various sources not least seeing tree diagrams of living creatures in general and insect in particular, I know that experts in this field (not just one dead friend) categorise butterflies and moths differently. The word of one dead friend (however expert) is not enough to say that I 'know'. Nor is it enough for me to believe (although the alleged word of one dead Jesus is enough for some to believe) I chose Red Admirals and Hawk Moths because I see a lot of these and have learned to identify them. There are many varieties that I could not distinguish as either a butterfly or a moth or even identify reliably as one of these varieties and not something else such as a damsel fly. (Are tapeworms insects?) So in summary these are facts: I know a Red Admiral when I see one, from repeated practical experience. By practical experience I can distinguish between a Red Admiral and a Hawk Moth. I believe almost to the extent of 'know' there is a difference between 'moth' and 'butterfly' from corroborative deduction and other indirect information. I know my depth of knowledge is insufficient to identify that difference (There are many small brown moths and butterflies on our moors I can't tell which is which; certainly the obvious differences between the Red Admiral and the Hawk Moth won't do) This is entirely in line with what I first said about this example. I hope the notion of 'depth of knowledge' bring clarification at the expense of reeuction in simplification. Thank you for finally answering my first question Yes, I think adding the missing word would improve the discussion. You may even find that further additions are warranted by the end of the discussion. On 30/10/2018 at 9:26 AM, studiot said: Your overlimiting proposition thesis is more like the man who sees a tree and says "Forest". Or the man who says "There are three platonic solids" Are these right or are these wrong? Yes your answer (predictably) identifies the question of the definition of Forest (and tree). There is a whole discussion to be had about this in the light of my recent experiences. I read in Saturday's Times that London is officially a forest since it has more than 20% tree cover. Last week I was looking at the photographic records of the great storm of 1953 in NE Scotland. Flattened tree trunks everywhere, none standing. Is that still a Forest? But both this and the subsequent question was designed to elucidate Truth and the non binary natature of right and wrong. Most common usage of the statement "There are X Platonic solids" are used to actually mean there are only or exactly X. In fact there are more than three, therefore there are three but that in not all of them. Note again my theme that the method of reduction misses possibilities and that Nature and the Universe is more complicated than our categorisation. This is not to say that Nature does not have a place for things which actually fit the categories, just that she is constantly spring suprises on us. 1
Reg Prescott Posted November 2, 2018 Author Posted November 2, 2018 Ah Studiot. I did my best, trust me, trying to bring some measure of clarity to what did not seem to me clearly articulated ideas (kept me up till 2:00am too! Haha!). I'm not blaming yourself for this. Probably my own fault. I was just trying to simplify in order to understand your intriguing example better; not with any intent to distort. Maybe I'll try again tomorrow, maybe not. Kinda sick of all the hypocrisy and nastiness on this site right now (this is not directed at your good self). But for now... 29 minutes ago, studiot said: I believe almost to the extent of 'know' there is a difference between 'moth' and 'butterfly' from corroborative deduction and other indirect information.

As far as I remember you did not understand the point Reg was trying to make. But I do not want to recap the whole argument again here. As far as I remember the discussion was about naive falsificationism, which nearly nobody adheres to anymore, except maybe a few naive scientists. I know that it can be difficult to keep calm at Reg's posts, because of his 'know-it-all' and cynical style, but if you feel angry because of that, just take a deep breath, and concentrate on the contents. Are you sure you understands what he says? If not, ask. If you are, give counterarguments; but do not dismiss them just out of hand. Philosophy is not trying to dismiss the other, but proof the validity of arguments. In my impression the threads were not just closed by Reg's tone, but also by those of others. Any discussion, be it in science, philosophy or daily life, is done best by taking a disinterested stance, by not identifying oneself with the arguments, and so feeling attacked when somebody does not agree with you. And again, @Reg Prescott, please temper your tone. It could be much more productive. Edited November 2, 2018 by Eise Stupid typo 2

Eise is correct in that you have to also examine the relationship between Language and Philosophy. You have found it necessary (and you are not alone) to introduce new words (language) to the discussion. 'Absolute certainty' in this case. Your comment only makes sense in the context of binary choices. I keep on banging the 'more complicated than binary' drum. It is physically possible for there to be an international conspiracy dating back centuries to hoodwink the non specialist in the classification of species (I don't even know if moths and butterflies are species or another term). But I consider the probability of that sceanrio to be vanishingly small. So I could be said to believe to the point of absolute certainty. But we then need to introduce the formal definition of probability and the fact that there are three different interpretations (all valid) for absolute certainty = probability of 1. 7 minutes ago, Eise said: As far as I remember the discussion was about naive falsificationism, which nearly nobody adheres to anymore, except maybe a few naive scientists.

Dennett is one of those strange people who subscribes to (a form of) "eliminativism", i.e. the mind and all her furnishings -- beliefs, desires, hopes, fears, even consciousness itself -- do not exist, at least as commonly understood. One could change your sentence in a way that it literally says the same, but completely changes its meaning: the mind and all her furnishings -- beliefs, desires, hopes, fears, even consciousness itself -- do exist, but not as commonly understood. Of course, the traditional science of consciousness is not very successful, and Dennett is pretty clear why: because our intuitions fail. Especially the intuition of the Cartesian theatre: dualists suffer from it, as do materialists denying that we have free will. 12 hours ago, Reg Prescott said: he only reality that he imputes to beliefs (and all the rest) is patterns of behavior. That is definitely not true: his method of heterophenomenology is not behaviourist. 12 hours ago, Reg Prescott said: Dennett's book "Consciousness Explained" might have been more aptly entitled "Consciousness Explained Away". That bon mot is found everywhere on the internet. Depending on how you understand it, it is true and false at the same time. Take one of Dennett's early favourite examples: a doctor explains the effectiveness of sleeping pills because it contains vitus dormitiva. Did he explain anything? Of course not. Explaining the workings of the sleeping pills must be build on lower level mechanisms. With consciousness is the same: trying to explain it with conscious subelements means that you did not even start explaining consciousness. At most you are are building up a phenomenology of consciousness. (there is nothing wrong with such a phenomenology, but it is no explanation of consciousness). So explaining consciousness means to explain by processes that are not conscious themselves. And where this principle is accepted in nearly every science, when it is about consciousness suddenly people raise up, complaining that consciousness is explained away. So, yes, the bon mot is true in the sense that every explanation is sort of explaining away, but it is false in the sense that it is a real explanation. Life is not explained away by pointing to the fact that life is 'nothing else' than a very complex chemical process. The 'nothing else' however is very tricky: one could understand it as 'chemical reactions are not life, so it means life does not exist'. Those who say Dennett 'explains consciousness away' do the same with Dennett's theory of consciousness. Do you really think that Dennett would say consciousness does not exist? 12 hours ago, Reg Prescott said: And as John Searle likes to scoff, whenever you meet one of these guys who deny consciousness, you just want to go up and pinch them. If John Searle thinks Dennett denies consciousness, then he is wrong. I am pretty sure Searle does not understand Dennett. And as he is still sticking to his faulty 'Chines room' intuition pump, he is disqualified in my eyes. 32 minutes ago, DrP said: It reminds me of this thread because their arguments always reduced down to just 'yea - but how can you truly know that' when given a logical progression of stating that 'of course it makes a sound - if you go by the dictionary definition of 'sound''. I think this is the whole point: the answer on the question depends on how you define 'sound': is it the vibrations in the air (then yes, the tree made a sound); or is it only sound when it is heard (then no, the tree did not make a sound). Philosophers should be trained very well in shifting of meanings of words. I notoriously get into these kind of problems when discussing e.g. free will. I can explain a hundred times what I understand under free will, but when arguing I soon observe that my 'opponents' return to their own meaning. Their intuitions about what free will is supposed to be are so strong, that they cannot leave it behind in understanding what I am trying to say. Dennett has the same problem with explaining consciousness: the intuition of the Cartesian theatre is so strong, that even when people understand the notion, when evaluating Dennett's arguments they unconscious (!) they fall again for the illusion. And as a real life example in this forum: ask Koti about see1 and see2... He probably gets a nervous breakdown when he reads this... 12 hours ago, Reg Prescott said: You're Dutch, right?

As far as I remember you did not understand the point Reg was trying to make. But I do not want to recap the whole argument again here. As far as I remember the discussion was about naive falsificationism, which nearly nobody adheres to anymore, except maybe a few naive scientists. I would suggest you review his past threads. He most certainly has/did make invalid scientific claims, but they are off topic here. Quote I know that it can be difficult to keep calm at Reg's posts, because of his 'know-it-all' and cynical style, but if you feel angry because of that, just take a deep breath, and concentrate on the contents. Are you sure you understands what he says? If not, ask. If you are, give counterarguments; but do not dismiss them just out of hand. Philosophy is not trying to dismiss the other, but proof the validity of arguments. In my impression the threads were not just closed by Reg's tone, but also by those of others. Any discussion, be it in science, philosophy or daily life, is done best by taking a disinterested stance, by not identifying oneself with the arguments, and so feeling attacked when somebody does not agree with you. I'm neither upset or in any other way angry at Reg's claims and his poor philosophical take on science. This is after all just a science forum and his claims here in time will be lost in cyber space never to be heard of again! That doesn't mean that I should not point out the most basic areas of false claims, erroneous judgements, continued claims of no agenda, and poor philosophical opinions that he is plastering this forum with. You question my understanding of what he says? My criticism is first and foremost directed at some of his fanciful conclusions. One prominent criticism of mine is his continued accusations against most on this forum, and the making of absolute statements, when it is he making those absolute statements. eg: He seems now to have backed away somewhat in his claim that science is the search for truth and reality, when it has been pointed out to him that this is not always the case.

Reg Prescott Posted November 3, 2018 Author Posted November 3, 2018 (edited) @ Eise, I enjoyed reading your comments above on Daniel Dennett's philosophy. You clearly know his work well and are passionate about it, as I am myself. By that I mean, Dennett is a delight to read, a creative, clever, and witty observer, and as you note, never afraid to challenge orthodoxy. Kudos for all that. It's just that, at the end of the day, I find myself in disagreement with almost everything he says. Haha! Clearly, you feel differently, and that's hunky-dory too. It is intriguing that our intuitions are pulled to extremes on the topics we've touched on. Those sympathetic to the Dennett camp look on his views being more closely tied to hard-nosed science, sometimes dismissing those of a more realist persuasion (e.g. John Searle) as "mystics". Conversely, those at the Searle end of the spectrum, including myself, find it hard to take Dennett and his ilk seriously since they appear to deny the very data which is most indisputable, i.e., our own mental life and its concomitant subjective, qualitative states: "qualia" (see below), or for the uninitiated, consciousness. Stub your toe, poke your eye, put your hand in a fire, or listen to Barry Manilow's Greatest Hits. Yes, that's qualia, of the pain variety. This is -- among other things -- what Dennett denies is real. I believe some things you said above are mistaken, Eise, and will try to provide evidence below to support this. Before we get started, though, I do want to emphasize that "winning" or "losing" is of little moment to me. It's a rare pleasure just to discuss these things with someone as obviously passionate, knowledgeable and intelligent as yourself. 20 hours ago, Eise said: Do you really think that Dennett would say consciousness does not exist? As far as I'm aware, Dennett has never come flat out and asserted "consciousness does not exist". With good reason, too -- people might think he's stark raving mad! Haha! But I do think, as many other commentators do, that's exactly what he's saying, just not in so many words. On occasion, he comes ever-so-close to stating it baldly himself, though always seems to back off slightly as if not quite daring to confess his sins. Take this passage, for example: Quote But he concludes, bizarrely, that therefore qualia are fictions, “an artifact of bad theorizing.” If we lack qualia, then we are zombies, creatures that look and even behave like humans but have no inner, subjective life. Imagining a reader who insists he is not a zombie, Dennett writes: “The only support for that conviction [that you are not a zombie] is the vehemence of the conviction itself, and as soon as you allow the theoretical possibility that there could be zombies, you have to give up your papal authority about your own nonzombiehood.” Think you’re conscious? Think again. https://blogs.scientificamerican.com/cross-check/is-consciousness-real/ To repeat for those who may not be au fait with the jargon, "qualia" just are these subjective states, those "what-it's-like"states, those raw feels, that we're all so familiar with. Pains, tickles, itches, orgasm (!), sadness, euphoria, the smell of cinnamon, the taste of Grolsch beer... These are qualia. These are the stuff of consciousness. Those of you who have no such states are invited to join Dennett in Zombieland for a dirty weekend of water, British food, Korean soap operas, and other forms of emptiness. 20 hours ago, Eise said: (The only reality that he imputes to beliefs (and all the rest) is patterns of behavior) - Reg That is definitely not true: his method of heterophenomenology is not behaviourist. Take a look at this then: Quote 1.3 Interpretationism Interpretationism shares with dispositionalism the emphasis on patterns of action and reaction, rather than internal representational structures, but retains the focus, abandoned by the liberal dispositionalist, on observable behavior—behavior interpretable by an outside observer. Since behavior is widely assumed to be physical, interpretationism can thus more easily be seen as advancing the physicalist project. The two most prominent interpretationists have been Dennett (1978, 1987, 1991) and Davidson (1984; see Donald Davidson). To gain a sense of Dennett's view, consider three different methods we can use to predict the behavior of a human being. One method, which involves taking what Dennett calls the “physical stance”, is to apply our knowledge of physical law. We can predict that a diver will trace a roughly parabolic trajectory to the water because we know how objects of approximately that mass and size behave in fall near the surface of the Earth. A second method, which involves taking the “design stance”, is to attribute functions to the system or its parts and to predict that the system will function properly. We can predict that a jogger's pulse will increase as she heads up the hill because of what we know about exercise and the proper function of the circulatory system. A third method, which involves taking the “intentional stance”, is to attribute beliefs and desires to the person, and then to predict that he will behave rationally, given those beliefs and desires. Much of our prediction of human behavior appears to involve such attribution (though see Andrews 2012). Certainly, treating people as mere physical bodies or as biological machines will not, as a practical matter, get us very far in predicting what is important to us. On Dennett's view, a system with beliefs is a system whose behavior, while complex and difficult to predict when viewed from the physical or the design stance, falls into patterns that may be captured with relative simplicity and substantial if not perfect accuracy by means of the intentional stance. The system has the particular belief that P if its behavior conforms to a pattern that may be effectively captured by taking the intentional stance and attributing the belief that P. For example, we can say that Heddy believes that a hurricane may be coming because attributing her that belief (along with other related beliefs and desires) helps reveal the pattern, invisible from the physical and design stances, behind her boarding up her windows, making certain phone calls, stocking up provisions, etc. All there is to having beliefs, according to Dennett, is embodying patterns of this sort. Dennett acknowledges that his view has the unintuitive consequence that a sufficiently sophisticated chess-playing machine would have beliefs if its behavior is very complicated from the design stance (which would involve appeal to its programmed strategies) but predictable with relative accuracy and simplicity from the intentional stance (attributing the desire to defend its queen, the belief that you won't sacrifice a rook for a pawn, etc.). https://plato.stanford.edu/entries/belief/ Finally... 20 hours ago, Eise said: Did you read that somewhere here?

Over 5000 hits for the word "know". Here's a sample: "... everything we know about a black hole is "available" at the horizon."

"Just because we don't know everything it doesn't mean we don't know anything. Science is constantly updating itself ..." "No it doesn't. This shows a profound lack of knowledge of how the brain works. Pretty much everything you see is created by the brain, and largely created by the brain to fool you." [unlike others who do not lack this knowledge - RP] "We know a lot about dark matter (less about dark energy)." "True. Obviously, I was only referring to what we currently know." "Also if you would go to MACS0647 and send me a tweet it would make no difference in your argument. We detected it that means we know where it was billions of years ago." "But the way you phrase it makes it seem like you are thinking of the time dimension as completely separate from the others. This is not the case; we know they are all inextricably linked." Oh, and this one kept popping up for some reason... "Science is what you know; Philosophy is what you don't know" Edited November 3, 2018 by Reg Prescott

There are many things that were once considered facts which we now 'know' not to be in light of updated evidence.

There are clear cases where everyone, or almost everyone, would agree that your tap is on or off. Thank you. And yet there is a world of difference between the state 'on' and the state 'off' in that there is a huge range from drip to trickle to running to full bore for the on state but there is no such range available to the off state. [philosophical aside] I all to often see folks trying to create some argument categorising a binary choice by defining the wrong quantity of a pair first , say xxx, (infinity and finite are good examples) and the other one as nonxxx. So here the correct choice is to define 'off' and everything else is 'not off' Doing it the other way round leads to logical difficulties [/aside] Edited November 3, 2018 by studiot
