I feel like I'm talking to a monk about zen. Which, of course I am not, so it's a shame.
Perhaps I have something in common with a monk, in that I think you can only understand some things if you see them for yourself.
You're just making the hard problem a lot simpler than it is.
I'm not making it simpler, I'm just dismissing it.
I hardly think of Chalmers as the crackpot of philosophy with no relevance.
I didn't say he was. What I said was that his line of reasoning would send him to the crackpot bin if he were a physicist, and that is because physicists don't have as much intellectual freedom as philosophers. For instance, no physicist can postulate the existence of an entity whose existence cannot be detected by any means; philosophers on the other hand make a living out of it.
A liar is someone who thinks one thing and says something else.
I don't understand why we should be debating the meaning of the word 'liar'. I told you it was crazy stuff, so just pretend I didn't say it. It's not essential to this discussion.
It seems like you are thinking of a zombie with all of the behavior of a conscious human being and claiming it to be nonsense. But it doesn't have to behave exactly like a human being to illustrate the problems of consciousness and experience.
What's with this "illustrate" thing you keep bringing up? You talk as if I haven't lived with my conscious mind for my entire life. What is there about my own consciousness which you think I don't understand?
Does a tree experience the feel of the wind?
How exactly would your understanding of anything change if you could answer that question? In other words, what other questions do you have whose answers depend on knowing the answer to that particular question? If you meet God today and He tells you, "yes, trees experience the wind", or "no, trees do not experience anything", how would that particular piece of knowledge fit with everything else you know?
You probably think I'm being cryptic, but I'm just trying to show you that you are asking a question that lacks meaning. You think the question can't be answered because consciousness is a diffcult problem, but to me the reason is far more mundane: when talking about trees, the concept of experience has no meaning. You can't say trees have experiences, and you can't say they don't. Just as you can't say whether trees are violent, romantic, whimsical, and so many other concepts. Do you think a tree has a sense of humour?
You're making me work much too hard to put your view into focus.
I appreciate your effort. Life can be difficult without those pills...
Beauty has nothing to do with it. Let me try again. Assume that it does everything I described and then says "This picture is red". Does it experience redness?
I could give you the same answer I did before, but then you would come back and tell me redness has nothing to do with it.
I already understood your point. Just because the robot says "this is red" doesn't necessarily mean it is experiencing red, beauty, whatever. I have no problem with that. But it absolutely doesn't follow from it that the experience of redness has nothing to do the physical process of seeing red. And it doesn't follow from it that there's more to experiencing red than the physical processes associated with the way humans experience red.
If your robot were made of flesh and bones, if it looks and behaves exactly like a human being, you would never doubt it has experiences. But then you wouldn't call it a robot. Do you realize that the word 'robot' already implies absence of experience?
Better yet, does something have to say anything or behave in anyway in order to have experiences?
The short answer is 'yes', because language is one of two criteria we use to establish consciousness in people. The other is behaviour.
And what has been suggested is to move from a view that says consciousness can be explained in terms of other facts (which is non-scientific) to a view that makes consciousness one of the postulates.
When I copied your quote above, I accidentally deleted one of the letters, so I had to type it back. I know which letter it is, and I know you can't possibly know. Even if I tell you, you'd have no way to know if I'm telling the truth. In fact, you do not even have a way to know if I'm not lying about replacing a letter to start with. Some imbroglio!
You see what's happening here? I am in possession of information about reality which has no bearing whatsoever on your reality. Which letter I took away and put back, or if I did it at all, is completely irrelevant to you. It's not part of your reality, but it is part of mine. So even though we share the same reality, we don't share our knowledge of it. We are all in possession of a good amount of knowledge about reality which simply cannot be shared, yet the reason it cannot be shared is simply because it doesn't matter to anyone but ourselves. Those things I know but cannot talk about do not have the power to tell you anything of any significance to you. You couldn't care less what truths I have in mind if you can't personally verify those truths for yourself.
What is science? It's shared knowledge, ideas about reality whose truth or falsehood can be established by every single independent observer. You may accept science or reject it, you may accept just a portion of it, but the fact of the matter is that you can know! Scientific knowledge is knowledge about things that are relevant to everyone.
You say science should account for knowledge only you have. I'm not denying that such knowledge exists, but I think people like Dennett are absolutely right when they say such knowledge is of no scientific relevance whatsoever. No paradigm change required, no new postulates. Behaviour can be accounted for on the basis of things we see; whatever else is left is of no relevance to scientists.
By the way, in case you want to know, it was the first 'A', right at the beginning of the sentence.
