I do not feel at all confident saying what the dog expects or recognizes. I could speculate that the dog ran into many people on a regular basis. I'll bet it got petted by dozens of people every day. I'll bet some people saw it regularly, and started bringing a treat when they could. If the man stopped coming, the dog still got tons of love and attention. What began for one reason continues for another. The dog might not remember the man at all.The dog expects their human to arrive. The dog recognizes that their human is not showing up. It is also true that it does not abandon its general expectation that their human comes back on the 5:00 train every day. — Ludwig V
Imperfect DNA replication. Which rarely happens. That's why the very very slow increments. I think single mutations aren't noticable. One base pair changes? That's nothing. But, in a million years, they've added up, and something is noticable.I take issue with taking certain kinds of leaps. "Increase" works well. Very very slow increments.

The detail of mutations remains unclear. What makes a mutation... a mutation? — creativesoul
Exactly. Although some things, like a pile of sand, are definitely made up of tiny units, we can't define how many are needed for it to qualify as a pile. My guess is that applies to consciousness.The moral of the sorites paradox is that some concepts do not have precise border-lines. Consciousness seems to me to be one of them. (So does "rational") — Ludwig V
I don't suspect we could ever learn what actually happened. Especially if it's the second scenario, that our brain gained an ability that subsequent mutations were able to build upon. We couldn't ever know the series of mutations, and what each one gave us.I wouldn't disagree with that or what I think it means. It could use a healthy unpacking. — creativesoul
If humans think in ways no other species does, such as thinking of our own death in the (hopefully) distant future, what are the common elements with the thoughts of whatever critter has the least activity that can be called thinking?Do all thought and belief share a set of common elements, such that they are the exact same 'thing' at their core? — creativesoul
I used a couple of specific examples to illustrate the very broad categories. I'd be surprised if there are examples is any non-human language of the broad categories of talking about the past or future.They were talking more broadly though than you I think ;) — I like sushi
Some animals eat what they can find."Greater" abilities??? I'm not sure what that means — creativesoul
I would be thunderstruck to learn this is true. Two examples jump quickly to mind, but I'm sure there are others.All elements of human language (spoken/written/signed) can be seen in the rest of the animal kingdom, it is just that we happen to possess them all. — I like sushi
Probably not all. Hehe. Anyway, I certainly hope it works out!"hello no, I am not going to let them believe they are right and all the emotional problems are because I have been so bad." — Athena
I don't see any other explanation having an easier time. One neuron? Two? A thousand? A million?I think it's the sorites problem. One bit of information processed doesn't mean anything. Many bits of information processed is more persuasive. But it's more than just processing information. It's reacting to it in complex ways, and, it's not just responding to information, but initiating action based on information as well. — Ludwig V
I've been accused of worse than that! :grin:I think any bit of information processing brings a little bit of consciousness.
— Patterner
H'm. I think that's a bit extreme — Ludwig V
I suspect we agree on facts. We've all heard the numbers of the percentages of DNA we share with various species. It is truly amazing that the differences between us are accounted for by such a small difference in DNA!!You didn't mention it in your account of how different humans are from animals. Mind you, I don't mention what you emphasize in my accounts of how similar they are. Perhaps it comes down to "glass half full/empty" - a difference in perspective rather than a disagreement about the facts. Then we need to tease out why that difference in emphasis is so important. — Ludwig V
Understandable. I don't think PZs are possible. I think any bit of information processing brings a little bit of consciousness. I was just trying to say what I think epiphenomenalism would need like. But, as far as consciousness goes, I don't think epiphenomenalism applies.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.
— Patterner
That's exactly why I can't do anything with your thought-experiments. — Ludwig V
This robot would have consciousness, thanks to the kneural knet. PZs don't have any consciousness.This is more towards philosophical zombies. — SophistiCat
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.OK. The PZs are supposed to be indistinguishable from normal humans, so that case is not relevant. — Ludwig V
Are you contradicting yourself? Or am I reading it wrong?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
I agree.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 have literally never heard anyone try to deny that anywhere, at any time in my life.Now we think about things, and kind of things, nothing else thinks about.
— Patterner
.. and yet we are still animals. — Ludwig V
At 32:10 of the video on this pageI 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
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
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.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
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.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
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.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
I agree.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. 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.Wanting to have some milk is the point of the causal sequence, not an epiphenomenon. — Ludwig V
Yes. But not my typo. Stupid Siri, or one of them.("neutral" is a typo for "neural", I assume.) — Ludwig V
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.My reductio aims to demonstrate that this argument is based on a misunderstanding of causality. — SophistiCat
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.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
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...Nicholas? Who's that? — creativesoul
It saddens me that I can't find the Burger King ad about Nicholas, who would rather eat hamburgers pickle-less.Well, I would concur that no one has been picklefree. :wink: — creativesoul
I'm free to do as I choose, regardless.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
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?A square circle is not either/ or and nor is it a paradox, It is just an incoherent conjoining of words. — 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?↪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
That's fine. But that wasn't the most important part. Walking certainly has an effect on physical events. How can it be epiphenomenal?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
I hadn't heard about whatever is happening in Alabama, and hadn't considered the test tube scenario. Thanks!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
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.)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
