    This is more towards philosophical zombies.SophistiCat
    This robot would have consciousness, thanks to the kneural knet. PZs don't have any consciousness.

    Obviously, something like a kneural knet would be found only in scifi. I'm just using it as an example off epiphenomenology. It gives subjective experience, but has no casual ability. If the robot acts without it, as robots we currently have do, then the addition of it would be true epiphenomenality (is that a word??).
  • Rational thinking: animals and humans
    OK. The PZs are supposed to be indistinguishable from normal humans, so that case is not relevant.Ludwig V
    My point is there couldn't be such a thing. As I've said before, just because we can say the words, doesn't mean we can conceive of them. Like a square circle.

    It depends. If they have sensory input, they are conscious, so I don't accept that we have robots like that. But I agree that we can strap a camera to a computer (or input an image) and program it to respond in certain circumstances. I understand also that we often call that seeing or calculating or speaking. But it's by extension from human beings, not in their own right. Getting it to do everything that we do is a different matter. I don't rule out the possibility that one day there might be a machine that is conscious, but I have very little idea of what it would be like.Ludwig V
    Are you contradicting yourself? Or am I reading it wrong?


    But I also don't think that consciousness is on/off, like a light and sometimes there may be no definitive answer.Ludwig V
    I agree.

    Now we think about things, and kind of things, nothing else thinks about.

    .. and yet we are still animals.

    I have literally never heard anyone try to deny that anywhere, at any time in my life.

    I do notice the frequent assertions on this forum that, although neuroscience can't yet 'explain consciousness', they will do at some point 'in the future'. I would include that tendency under the same general heading.Wayfarer

    Chalmers says:
    But that doesn't mean that we have to now sort of put our heads in the sand and say, "Well let's just wait and see." We can start thinking about why is the problem as hard as it is. And what is giving rise to this systematic difficulty.Chalmers

    The brain's activity could do these things without any subjective experience/consciousness anywhere.
    — Patterner
    The problem is that your thought-experiment only works if I pretend that I accept this. It begs the question. (This is about the P-zombies, isn't it?)
    Ludwig V
    No. I really like Chalmers. Most of the time. But PZs are just dumb. A planet that never had consciousness, but had our intellectual abilities, would never come up with three concept of consciousness. They wouldn't ever talk about it, or have words for it.

    But why do you disagree? Don't we have robots that perform certain actions when they get certain sensory input?
  • Abortion - Why are people pro life?

    I didn't say any time we kill a human, we get charged with murder. And I gave examples of times we kill a human and do not get charged with murder.

    What I meant is that the only thing that gets a charge of murder is killing a human. Not killing anything else, or even a million something elses.

    The difficulty is setting out the ways we're similar, and the ways we're unique. Our own thinking is bolstered by our own complex language use and all that that facilitates. Naming and descriptive practices are key. They pervade our thinking. They allow us to reflect upon our own experiences in a manner that is much more than just remembering.

    Other animals cannot do that.
    creativesoul
    Right. But millions of years ago, our brains took a leap that no other species has yet taken. We were one of many species that had some limited degree of language, or representation, abilities. Presumably, various other species have evolved greater abilities since then. (Maybe whatever species today has these abilities to the least degree is the baseline that all started at. Although even it may have evolved from the barest minimum degree of such abilities.) But our brain gained an ability that was either enough for us to get where we are now by learning and adding to our learning, or that subsequent mutations were able to build upon. It allowed us greater language, and our greater language helped develop our brain. Now we think about things, and kind of things, nothing else thinks about.
  • Rational thinking: animals and humans
    According to the definitions I quoted earlier, epiphenomenalism says mental states do not have any effect on physical events. Walking is a physical event, not a mental event. And walking certainly has an effect on physical events. So I don't know how you are thinking walking is epiphenomenal.
    — Patterner
    Well, the fact that mental states make me walk to the shops demonstrates that epiphenomenalism is false.
    Ludwig V
    The brain's activity could do these things without any subjective experience/consciousness anywhere. And I'm sure we're making robots that prove the point. But let's say we add another system into the robot. Let's call it a kneural knet. The kneural knet observes everything the robot is doing, and generates a subjective experience of it all. We built and programmed the kneural knet, and we know it absolutely does not have any ability to affect the robot's actions.

    Isn't this what epiphenomenalism is saying?


    It seems to me a complete misunderstanding or misrepresentation to say that the screen display is an epiphenomenon. The screen display is the point of the whole exercise.Ludwig V
    I agree.


    Wanting to have some milk is the point of the causal sequence, not an epiphenomenon.Ludwig V
    I agree. Our subjective experience of it is not like the robot's. Our actions will often look like the robot's. But, with or without the kneural knet, the robot will do only exactly what it was programmed to do. Whereas I do not have programming that requires me to do only one thing from among what, to an outside observer, appears to be many possible options.

    Yes. But not my typo. Stupid Siri, or one of them.
  • Rational thinking: animals and humans
    My reductio aims to demonstrate that this argument is based on a misunderstanding of causality.SophistiCat
    Sadly, I don't know enough to understand your attempt. I'm reading all kinds of things. Haphazardly, since I'm just singing it. So probably unproductively. But maybe I'll get there. SEP seems helpful.

    However, the difference between neural activity/consciousness and moving feet/walking is vast. I can't even see any common ground.
  • Rational thinking: animals and humans
    My starting-point is that human beings are animals. We have bodies in the same way that they do. We have instincts which dominate our lives just as they do. Pretending we are not animals is something that are very much tempted to do, because we spend much time and effort trying to distinguish ourselves from them. But most animals do that in one way or another. For the most part, species prefer not to share their homes, roosts or whatever with other species. So that desire is shared with other animals as well.

    When someone tries to find some respect in which humans differ from animals, what I hear is a desire to pretend that they are not an animal. But they eat and sleep and do all those animal things. How are they not animals - admittedly an animal with over-developed capacities? But that doesn't change the foundation.
    Ludwig V
    Absolutely true in all respects. But I see the opposite. I see people denying there is anything different about us. As though any animal is capable of being educated and made able to build a skyscraper, build the NYC skyline, develop calculus, write string quartets, build the internet, and have these same conversations. Despite being very similar in almost all ways, we can think in ways no animal can. The proof is, literally, everywhere we look.

    Nicholas? Who's that?creativesoul
    I'm likely a bit older than you. BK commercial from late 60s-early 70s. Not sure I'm remembering it word for word, but...

    There once was a boy named Nicholas
    Who would rather eat hamburgers pickle-less
    So off he did bounce to proudly announce
    "I'm a very nice kid, but particle-less"
    Now the Burger King lady said, "Nicholas,
    "if you'd rather eat hamburgers pickle-less
    "Then all I can say is have it your way."
    [Nicholas] "'Cause anythinh else is ridicle-less."
  • Rational thinking: animals and humans
    Well, I would concur that no one has been picklefree. :wink:creativesoul
    It saddens me that I can't find the Burger King ad about Nicholas, who would rather eat hamburgers pickle-less.
  • Facts, the ideal illusion. What do the people on this forum think?
    There is no worry or possibility that we will ever stop thinking. If there are answers, and we find answers to any number of questions, there will always be more questions to ask, and more to think about.

    Welcome to TPF!
  • Are beasts free?
    Since there is no God, there is no one to conceive humanity before it exists, thus the human being has no nature before he (I write as sexistly as Sartre) exists. Therefore, he is free to do has he chooses.Jedothek
    I'm free to do as I choose, regardless.

    A square circle is not either/ or and nor is it a paradox, It is just an incoherent conjoining of words.Janus
    If my analogy isn't good, can you answer the question anyway? Many people think these two things are mutually exclusive. It doesn't seem unreasonable to think they are. You say they are not, and we should ditch the either/or thinking. I don't see how it is possible that they are not in an either/or relationship, and cannot simply change my thinking on three matter. If you are right, and ditching either/or thinking is a valuable thing, I'd like to know how to get there. Can you explain how these two things are not in an either/or relationship?
  • Rational thinking: animals and humans
    ↪Wayfarer Of course they do, but we also act for reasons. As I keep trying to get you to see they are just different kinds of explanation. You might get it if you ditch your either/or thinking.Janus
    What if the either/or thinking is correct? There are either/or situations. A square circle is either/or. It's not both. It's booty a paradox. It's just wrong. Why would I think this situation is not another?
  • Rational thinking: animals and humans
    According to the definitions I quoted earlier, epiphenomenalism says mental states do not have any effect on physical events. Walking is a physical event, not a mental event. And walking certainly has an effect on physical events. So I don't know how you are thinking walking is epiphenomenal.
    — Patterner

    I already addressed this. The causal exclusion argument that motivates epiphenomenalism applies equally to physical events in a similar supervenient relationship.
    SophistiCat
    That's fine. But that wasn't the most important part. Walking certainly has an effect on physical events. How can it be epiphenomenal?
  • Rational thinking: animals and humans

    Also, walking is moving our feet. For simplicity, it's the word we use instead of spelling out the whole process. I don't say;
    While upright, which is possible thanks to visual cues and the delicate workings of my inner ear, I moved my feet, alternating them, always placing the rear one in front of the other, until I found myself at the store.

    instead, I just said I walked to the store.
  • Abortion - Why are people pro life?
    So, if abortion is declared illegal in a very broad way, you end up with unintended consequences like what happened in Alabama. In vitro fertilization became illegal because the fertilized eggs in test-tubes were considered people because human life began at conception, which means their disposal was murder.Hanover
    I hadn't heard about whatever is happening in Alabama, and hadn't considered the test tube scenario. Thanks!
  • Abortion - Why are people pro life?

    Good points. But I'm wondering. We can say therr are just killings of people. For example, it's not murder when we execute a convicted murderer. Or when we kill in self-defence. But what is an example of a just killing of a fetus? When it puts the pregnant woman's life in danger seems like an obvious example. Any others?
  • Abortion - Why are people pro life?
    I think we should be consistent. If it's murder then so is abortion. If abortion is not murder, then neither is this.
    — Patterner
    H'm. You didn't cover "If it's not murder, ..." Given what you've said, if it's not murder. abortion is not murder. It's vicious nasty crime, but who was killed? No-one. So it's not murder.
    Ludwig V
    What do you mean I didn't cover that? That's what I said in the third sentence you quoted. In short, either they're both murder, or neither is. (That is, if the law is consistent.)
  • Abortion - Why are people pro life?

    Yes, of course. If the law says it's murder, then it's murder. And the law says murder only applies when the victim is a human being. Kill someone's cat or dog, and you are not charged with murder. It's illegal, and you'll be charged with something. But you might be in more trouble for how you killed the animal than for the fact that you killed it. Like if you use the gun in a residential area. Of course, those laws are different from one area to another.

    Kill someone's herd of cattle, and you are not charged with murder.
  • Abortion - Why are people pro life?
    If someone was to slip an abortion pill in a pregnant woman's body without her knowing and it results in the death of the foetus. Whether or not the person would be arrested for murder depends on your standpoint on abortion?Samlw
    No. It depends on your standpoint on the status of a fetus. We are only charged with murder if we kill a human being. If a fetus is a human being, then it's murder.
  • Abortion - Why are people pro life?

    I think consistency is important.
  • Abortion - Why are people pro life?
    So this is part of the argument that "becoming human" isn't a single moment, a single event, but a process. Is that what you were getting at?Ludwig V
    I think we should be consistent. If it's murder then so is abortion. If abortion is not murder, then neither is this.
  • Rational thinking: animals and humans
    So, if moving your feet does all the causal work, then walking is reduced to an epiphenomenon.SophistiCat
    Trying and trying to figure out what you mean, but I'm not getting it. But I feel this sentence is key. Can you explain the relationship between moving your feet and walking? (Of course, we're not talking about sitting in a chair and shuffling your feet around. Or lying on the ground doing leg-lifts. Or pumping your legs on a swing to gain height. Or any number of things other than moving them in the way that produces walking.)
  • Abortion - Why are people pro life?
    I don't understand. It doesn't harm her if she want the abortion, so sneaking would not be necessary. But it sneaking is necessary, then it's likely that she does not want the abortion and in that case, it definitely does harm her.Ludwig V
    What I meant is, if she wants to have the baby, and you sneak drugs into her food so it aborts, it's not murder. Men have been known to punch a woman in the stomach so they abory. Sad if she wanted to have a baby. But if it's not a child, and had no status on the eyes of the law, then the man is only guilty of assault & battery. The fetus is irrelevant, as far as criminal acts goes.

    I don't know if that's how the law actually looks at the issue anywhere. But if abortion is legal somewhere, I have to assume that's how the man's (and I use that term extraordinarily loosely) defense attorney would approach it.
  • Abortion - Why are people pro life?
    Many believe a fetus should have the same consideration as a child.
    — Patterner
    .... and many do not. Should not the parents have the right to their own conscience?
    Ludwig V
    Many believe not.

    But if we aren't talking about a child, I don't think "parents" is the right word. There is only a pregnant woman.

    And, again, sneaking drugs into a pregnant woman's food so that she aborts, as long as it doesn't harm her, is no worse than breaking her window. Breaking her window is worse, in fact, because she had been sitting at it for years as it protected her from the cold and rain, looking at the beauty of nature, watching her husband pull into the driveway when he comes home from work.
  • Abortion - Why are people pro life?
    Some think a fetus is a stage in the life of a human being, so nobody should have the right to choose what to do with the fetus' body.
    — Patterner
    That's absurd. Parents (biological or other) not only have the right, but the duty to make decisions about their children's lives. Why should there not be a similar right and duty to make decisions about a foetus? After all, we allow people to make decisions for their relatives when they are ill and unable to make the decisions themselves.
    Ludwig V
    You're talking about the right and duty to make decisions about their children's lives that are in the best interest of their children. Even when we disagree on what is in their best interest (Raise them with religion? Home-school them? Allow them to drink soda?), we almost always let the parents make the decision. But we don't allow parents to make the decision to end their children's lives because they no longer want to raise them, can't afford to raise them, or regret having had them. Many believe a fetus should have the same consideration as a child.
  • Rational thinking: animals and humans

    I don't understand how you mean things. What is epiphenomenalism?
    Epiphenomenalism is the view that mental events are caused by physical events in the brain, but have no effects upon any physical events.SEP
    Epiphenomenalism is the view that phenomenal properties – the what it’s like of conscious states – have no physical effects.Emerson Green
    relating to an epiphenomenon (= something that exists and can be seen, felt, etc. at the same time as another thing but is not related to it)Cambridge Dictionary
    of or relating to an epiphenomenon (a secondary phenomenon accompanying another and caused by it /
    specifically : a secondary mental phenomenon that is caused by and accompanies a physical phenomenon but has no causal influence itself)
    Merriam Webster

    In what way does the physical act of walking fit any definition of epiphenomenal? I may be misunderstanding your questions.
  • Rational thinking: animals and humans
    If walking consists in putting one foot in front of the other, is walking epiphenomenal?SophistiCat
    I would not think so. But wanting to walk would be, as wanting milk would be, if we are nothing but physically deterministic machines.
  • Abortion - Why are people pro life?
    Around 60% of the world’s population has the right to an abortion. And in the interest of freedom and not allowing a government to have control on what life choices you want to make with your personal body,Samlw
    Some think a fetus is a stage in the life of a human being, so nobody should have the right to choose what to do with the fetus' body.

    Some think it is wrong to abort even if only moments after conception, because conception is the beginning of unique human DNA. Again, that being a stage in a human being's life.

    Some think that, if the fetus does not have rights, because it is not alive, or isn't human, or whatever the criteria, then destroying it without the pregnant woman's permission isn't any more of a crime than an abortion is. (Assuming no harm is done to the woman, obviously.)
  • Rational thinking: animals and humans
    Why would we not experience wanting? Why compare us to robots? We are not robots we are evolved organisms.Janus
    I'm comparing us to an example of something that unquestionably operates entirely within the bounds of physical determinism, in order to show why I think we do not.
    -Robots do not have any subjective experiences of the electrical activity within them by which they detect sensory input, discriminate this input from that input, and act based on what they are currently detecting. We do. Why don't they? Why do we?
    -Building on what we have that something operating entirely within the bounds of physical determinism does not, we are aware of our subjective experiences. We talk about them all the time.
    -Building on top of that, we are aware that we are aware of our subjective experiences.

    That seems to be a lot that physical determinism needs to explain. Why any difference at all, and how those three differences are accomplished.

    Even if we could observe in living detail the neural processes we cannot observe conscious experience, so establishing the link between the two would still seem to be impossible, as far as I can imagine. Of course I might be mistaken, I won't deny that.Janus
    We don't have reason to think otherwise. But sure, it's possible we'll discovery something or other one day.
  • Rational thinking: animals and humans

    Right. But, if all is physical determinism, then why would we experience the wanting? A robot that is programmed to fill a cup with water when its sensors detect it is empty doed not "want" water. Nor does it experience the electrical activity that senses the low water level, or that moves the parts that refill the cup. It's all just mechanical stimulus and response.

    Body needs a nutrient that is found in milk. Brain initiates action potentials to move body to open refrigerator to get milk. Photons bouncing off of contents of refrigerator do not hit retina in a pattern that closely enough matches any patterns representing milk that have been stored in the past. Brain initiates new action potentials, so body goes to store.

    There is no wanting in that description, and no need of wanting. Stimulus and response accomplishes what is needed. The subjective experience of the need for that nutrient is not necessary.

    But the subjective experience is there. One would think because it is an evolutionary advantage. But if it is only the subjective experience of the neutral activity, and is not causal, then how is it an advantage?

    And, advantage or not, how is the subjective experience accomplished?
  • What is love?

    Humans are the worst. It's hard to articulate how stupid we are. We know love is the best thing about life. We know you can't use it up, because giving love only generates more love. And yet, we so very, very ... very often blow it.

    Pride is one of love's biggest enemies. I can hold my pride tight, or I can give and receive love. I can't do both. They're mutually exclusive.

    As Ed learned on Northern Exposure, low self-esteem is also a big problem. It's difficult to accept love when you don't think you're worthy of it. And it's difficult to give love when you think your love isn't worthy.

    Fear. "What if it's too late?" "What if s/he doesn't feel the same any longer?" But, if you don't try, you definitely lose.
  • Rational thinking: animals and humans
    Say I go to the shops for milk. If someone asks why I went to the shops I'll say it was to buy milk. That's one explanation. On the other hand, I could say I went to the shops because the neural activity which is experienced as realizing I was out of milk and neural activity which is experienced as wanting to have milk led to neural activity which led me to go to the shop.Janus
    I guess there are those who say the neural activity isn't experienced as wanting to have milk. Rather, the neutral activity is wanting to have milk. Experiencing the neural activity vs. the neural activity being the experience. The latter being the case if we are ruled by physical determinism. In which case, the "wanting to have milk" is, I guess, epiphenomenal, and serves no purpose.
