    Consider, you might ask me what a horse is. I'd say it's the thing I'd name "horse".Michael

    Then I'd ask if you were an idiot. That's not the appropriate way to answer that question, obviously.

    Horses aren't just the things we call horses -- for example, if we stopped calling anything 'horse,' there would still be horses. Unless you have the incredible power of making all horses disappear by never uttering 'horse.'

    I'm sorry if my fuse is short, but I'm so tired of this line of thought.

    I'm not saying that if we stop calling this animal "horse" then it disappears. I don't know how you've managed to derive that from what I've said.

    That's not the appropriate way to answer that question, obviously.

    Then how would I answer it? Perhaps by showing you a horse? So let's say I show you two animals. Which one is the horse and which one is the rabbit? The horse is the one that, if shown to you, would predictably have you respond with "yes, that is a horse" (because the output "yes, that is a horse" is (one of) the appropriate thing(s) to say given the input).

    So I think my answer was quite appropriate.

    If a horse is that which you call 'horse,' it follows that if you do not call anything 'horse,' there are no horses. If there used to be horses but aren't any more, that means all the horses disappeared. QED.

    I can't list the conditions that must be satisfied to make something a horse (if we use your example above then consider that not all horses have manes), or show you a horse (unless we met in real life).

    And how can I point to a horse during an online discussion? All I can do is tell you something. So what sort of thing can I tell you? I could perhaps list the necessary and sufficient conditions, but of course such a thing is impossible, and then of course someone could ask me what legs and manes and horseshoes are.

    At some point one has to assume that the other understands the description. And what does understanding the description consist of? Knowing the empirical situation in which such a description is the appropriate thing to use. So I've just cut to chase and gone straight to this.

    And when it comes to something like grief or red or happiness, I can't even break it down into some components parts (like I could do in a generalized way with horses). All I can do is say that they're the things that I name "grief", "red", or "happiness", and hopefully there are things that you name "grief", "red", and "happiness", and so you understand what I mean.

    Yes, it's uninformative. But how can I provide an informative account? Your response "grief is a feeling" is also uninformative because plenty of feelings aren't of grief. Which feeling is grief? What's a feeling, even?

    And knowing what falls under "rabbit", "mane", "small arms", etc.? You can't avoid the fact that when push comes to shove knowing what these words means is knowing when to use them. At some point you tie them to some empirical situation in which such words are the appropriate response.

    Just because it isn't maximally informative doesn't mean it's uninformative: there are also lots of things that are not feelings that this rules out.

    Also, your offer is not just uninformative, but outright misleading: when someone asks you what something is, they're asking you to characterize it, viz. to give an account of what sorts of qualities make it that sort of thing.

Of course, this doesn't help the person who doesn't know when they would say such things, but I assume you're not such a person.

    I didn't engage in a circular appeal to linguistic behaviour. I referred to the empirical situation. But the only way I can refer to the empirical situation to which the word "grief" is tied is to use the word "grief".

    Second, simply because we do not relate to a computer as well as we do to other humans doesn't mean a computer doesn't feel. The recent movie Ex Machina explores this. To treat humans above computers simply because we don't have an emotional attachment to the latter is to have an anthropic bias.darthbarracuda

    One response to Searle's Chinese Room thought experiment is the system reply. Another one is the robot reply. Those two responses are quite different in character. That's because Searle's original contention was that however our brains "generate" understanding -- as they allegedly can, according to him -- can't be something that occurs in virtue of computation alone. All the system does still merely consists in manipulation of input symbol strings in accordance with syntactic rules. A robot does other things. It can actively gather data (not restricted to symbols provided to it) and behave in the world.

    It seems to me that Searle ought to be able to consistently accept that the robot can manifest understanding while still denying that its "brain" understands anything. Searle's rejoinder to the system reply still validly applies to claims that the robot's brain (i.e. its central controlling system) understands. Searle ought to grant that, if the robot manifests understanding of Chinese (and of its surroundings) in its public behavior, then this understanding may be enabled by its brain functions but isn't constituted by those functions.

    Of course Searle actually reject the robot reply. But that's because he is an internalist about intentional content. As I phrased it above, he believes that human brains "generate" understanding on their own quite appart from their embedding ("embeddedness"?) in animate bodies, and the embedding of our living bodies in our social and natural world. He defends a view of intrinsic intentionality according to which meaning and understanding (and reference) are produced by some irreducible and emergent property of biological brains -- irreducible, that is, to computations or syntactic manipulation of symbols. If we dispense with Searle's intentional internalism (i.e. the idea that mental states supervene narrowly on brain states, and depend only on them) then we ought to be happy to deny, with him, that computers understand anything. But we can also accept, unlike him, that sophisticated robots could conceivably understand, and yet deny, unlike him, that our own brains understand anything.

    Do you actually have anything meaningful to say about the difference between humans and computers such that we have reasons to believe that the one understands grief and the other doesn't?Michael

    The difference between a computer and a human is flesh. Flesh and computer metal are both matter, but flesh has the biological characteristics that produce the experience of grief (or any other emotion). What is that experience? Flesh experiences pain, for instance, and weakness, excitation in the diaphragm, swelling (a lump in one's throat), fatigue, and a whole set of emotional states and feelings we call grief (or happiness, excitement, remorse, anger, etc.). We experience them because they happen in our flesh (they aren't symbolic) and we have the capacity to experience and interpret our fleshly state. If you burn your hand, you feel intense and enduring pain. You can see that the skin on your hand has been severely damaged by heat, and you can feel it. Lots of animals can match this experience because they have flesh, nerves, and the capacity to feel pain.

    Beings or devices which lack the means to experience their own flesh (insects, worms, wood ticks, etc. or computers which have no flesh at all, can not have feelings or experiences. "Experience" belongs uniquely to flesh and the ability to apprehend. That which is without flesh cannot have experiences. What a human experiences in their flesh isn't symbolic, numerical, computational, or algorithmical. It's biological.

    If you built a suffering computer, it would consist of many biological features, and have the capacity to experience emotions and pain. Then a computer could suffer. Suffering begins in a kind of substance which machines (metal, gears, wires, transistors, semiconductors, quantum effects et al) don't have.

    Interesting that you mentioned that movie, since the machine in the movie manipulated the feelings of the protagonist in order to accomplish some other goal. The protagonist felt empathy for the machine and wanted to help it, not realizing that he was being fooled.

    There is another movie along these lines where journalist with a background in robotics is invited to do a piece on a successful roboticist. Turns out this person has managed to create a very human-like android and he wants the journalist to examine it. She ends up falling in love with the roboticist, and a bit disturbed by the android, because it's awkward in conversation, and begins to exhibit signs of jealousy and sexual interest.

    Turns out, the roboticist is actually the android, and the android is the roboticist. She's been fooled to see if the mimicry could be carried out convincingly, which it has, since she's fallen in love with a machine that's been programmed to mimic being a self-confident genius. The real person is a less convincing, awkward, but brilliant human.

    So the presence of emotions is determined by public behaviour. Then if a robot behaves the same way a person does, e.g. saying "I'm sorry for your loss" when you tell them that your father has died, accompanied with the appropriate facial expressions and body language, then the robot has demonstrated his capacity for emotions.Michael

    No, it's not. A person can fake emotions, afterall. I might be convinced that you're sorry (or the robot), but maybe it's just mimicry. Maybe you don't actually feel sorry. Maybe you didn't like the person who died, or me, or just aren't close to the situation. Maybe you just aren't feeling empathetic. But you want to maintain a polite appearance.
