SW VandeCarr said:As for dualism, I don't accept there is a "mind-body' problem" in the same way as physicists don't accept that there is a fundamental problem with physics just because they cannot observe events outside our light cone or inside black holes.
Maui said:It's FACT that my mind employs unscientific top-down causation and my conscious choices are REAL.
Of course not. There is also Quantum mechanics, etc. An there is also a lot that can be known, but we don't know it yet.Maui said:On a side note, what if not everything is reducible to classical physics?
Upisoft said:You feel it that way. Your feelings about the subject are no proof. If your choices were real then your dream world would be a reality.
Upisoft said:You feel it that way. Your feelings about the subject are no proof. If your choices were real then your dream world would be a reality.
Maui said:Observational evidence is proof in science. Whether they are fundamentally wrong is not a scientific question. You should not mix science and philosophy, as sciences do not deal with fundamental truths.
Maui said:Okay, i won't hold you accountable for what you said, since it wasn't your mind that made the decision to state what you did, but the inveitability.
On a side note, what if not everything is reducible to classical physics? What would it take for you to believe that what you experience is real and actual?
Upisoft said:There is no other observer of your feelings. You cannot have objective observational evidence.
SW VandeCarr said:I do believe my personal experiences are real. I also believe that consciousness is an emergent property of brain function. You agreed that emergent properties are part of nature and do not require a fifth force or some non-physical explanation. This discussion should have ended there. Perhaps you just like to argue.
Perhaps you could explain what you mean by top-down causation. There's no doubt that our thoughts and feelings result from our interactions with the environment.
Also, I don't doubt that 'mind' is a legitimate concept. You can give someone "a piece of your mind". That's doesn't equate to giving someone a piece of your brain. Brains communicate with each other creating larger emergent structures.
And yes, not everything is reducible to classical physics. We've known that since the 1920's. We also are just beginning to find ways to study emergent phenomenon and complex systems. But they are still part of nature and therefore "physical".
Maui said:But there is a very definite difference between dreaming and being awake. It's an assumption after all, but if you don't make it, what do you suggest we do?
Even if i am lucid dreaming everything while i am awake, what benefit does it bring over the situation when i assume that i am not? It's self- and socially destructive to think this way of existence and reality.
Upisoft said:If there is difference, and that difference being the objective world, then your choices are not real. They are the dreams (a virtual reality that your mind emulates).
Some of them become reality if you are able to find way to express them in the real world.
There is nothing unscientific in your brain function. It is just unique, and therefore your virtual reality emulated by your brain function differs from the virtual realities of all other people.
Maui said:If your consciousness/mind is an emergent property, then you are a dualist.
Not only. There is no enviropnmental reason why i should sing songs or paint pictures or suffer emotionally for lost relatives. But this is kind of obvious, isn't it?
Then you must point a way to measure how a mind makes a decision.
Then you have never been frustrated. Lucky you.Maui said:Then they are ALL real since i can express them all all the time, any day of the year.
There is no "top-down" causation. There is just causation. It is only one kind. What you are talking about is the illusion(virtual reality) that the brain creates.Maui said:Top-down causation is currently considered unscientific, hence the "paradoxes" about our conscious choices.
Maui said:Anyone who considers the current state of science complete is deeply ignorant of the deep fundamental and conceptual problems that plague physics and biology.
Maui said:It's FACT that my mind employs unscientific top-down causation and my conscious choices are REAL. The current scientific paradigm cannot explain this FACT, it can only deny it, because it makes NO sense to scientists. But scientists who consider their knowledge in the field final and true arent much better then creationists.
That "successful" theory posits that I can't raise my hands or that what I experience is an illusion. That theory is born out of the desire to prove that science has discovered almost everything. This is a religious belief probably designed to fill in gaps in our current knowledge.
SW VandeCarr said:Why? Is dualism nothing more than admitting we don't know everything?
We can't observe or measure what goes on inside black holes. Does that invalidate science?
How do you even know you have relatives or that there are such things as songs?
As for emotion, that's a personal experience.
Others can only observe your behavior. I already addressed this in previous posts. I'm confident there are physical correlates to our thoughts and feelings which can be observed.
Why? If you could go back in time, would you expect Isaac Newton to point a way to measure electromagnetic phenomenon (volts, amps, etc)?
Maui said:If you posit that black holes do not exist because we don't understand them, then your "science" is in deep trouble.
Pythagorean said:Your whole post pretty much relies on this statement of willpower. Science has actually investigated the matter and the results are somewhat discouraging for the case of willpower. It's fairly easy to find the research on the internet, but if you want links, let me know.
As a starter, if you have a healthy brain, you're not going to be able to stick your hand on a piping hot stove, drown yourself, starve yourself when your know there's food, hold in your digestive function, the list goes on. What's stopping you from doing all these things? The simplified answer is inhibitory neurons that care more about your survival than your intellectual self does.
When a species adapts such that they don't have to work as hard for survival, attention is reflected inward, noise becomes more significant, the random stream of consciousness begins to randomly manifest itself. Every once in a while (in the history of billions of human beings) the random thoughts add up to something significant in the environment that was previously observed, but not understood, and through social mechanisms, the organisms are able to convey the information and hold on to it and teach it to their young. As the young learns new information, it changes their behavior: the experience of pain deters you from repeating painful actions. Temptation towards available pleasure is often irresistible unless the greater consequences are fully realized. Many human actions are nothing more than reactions to emotional experiences which are indicators of survivability. Of course, when an organism is bored (no pleasure available or pain warning of threats to survival) then returns the random noise, based on past observations that we can somehow, by chance, make sense out of. But usually not.
This is completely false. The successful theory does not posit that, nobody has claimed that science has discovered almost everything, nor do most practicing scientists have any desire to prove it, nor is the theory born out of any other desire than that to understand nature. It's well recognized that answering a question in science leads to more questions. It's also well understood that no one man can hope to understand his whole scientific field (or even a subfield of his field) in a lifetime. Nature is too complex and diverse (in more ways than just life). Much too complex and diverse for you to start guessing what it can't do, especially in the light of such suggestive evidence.
Maui said:As soon as anyone(scientist or not) declares that coscious choices are an illusion, they are transgressing their field of knowledge and entering the void of ignorance with a set of WILD speculations. This isn't science.
Pythagorean said:Many human actions are nothing more than reactions to emotional experiences which are indicators of survivability.
Pythagorean said:That wasn't his argument at all. He was stating that the lack of direct observation of black holes doesn't prove they don't exist.
Anyway, I can tell by now that you don't really want to have a discussion. You are already set in your ways.
Pythagorean said:Replace "coscious choices" with "physical causality" and back 'atchya.
http://videogames.yahoo.com/events/brain-teasers/optical-illusion-17/1412563"Maui said:If conscious acts are observed, they are fact. Since there is someone WHO observes, there are conscious act and observations. This is an undeniable FACT.
Upisoft said:I think that all of our actions are based on emotional experience. Some of them are those you are talking about. Direct reactions of emotional experiences, i.e. impulsive actions. Others contain "rational" component, what we call thought. I say "rational", because even people want to be completely logical, they make logical mistakes. Nevertheless how logical is one's action it always is based on emotional experiences (I include here all autonomic functions and reflexes).
For example, consider the question "Why is life worth to live"? Can anyone give a pure logical reason? I doubt it.
If you were willing to watch an experiment about willpower where an fMRI machine is able to predict people's choices before the people have made them based on their neural activity, then maybe you'd actually gain some more understanding of my stance.Maui said:Care to show me the "physical causality" in an EEG or other examination of your choice as to how my choices are born and how they determine my volitional acts?
Being bored is emotional state. Negative one. People will tend to go away from that state. Some may go to the local strip bar and some may start searching the answer of the question about Life, Universe and Everything. In any case they have something in common, they are doing something that distracts them from the boredom. Some may even consider adding 2 and 2, but doing so is already success itself, as it helps them to avoid the boredom. Well, boredom is not always the reason to add 2 and 2. You may actually counting sheep or something.. :tongue2:Pythagorean said:I mostly agree with you, but I think people can be largely disengaged from emotional thinking when they're bored or dissociated. I guess it depends on where you draw the line between emotional and computational. I consider myself adding 2+2 a computational operation. It is ultimately driven by emotion, I guess, though. The excitement of an answer or the prospect of success.
Pythagorean said:I think it's largely because the question is not logical. It assumes that life is always worth living, which is not necessarily the case. Worth is a measurement of the value of the current situation, which changes depending on a) the situation and b) the state of the human brain. A weak brain in a high-stress situation may easily find life not worth living, but you throw a dog a bone every once in a while and even moderate-stress situations become more palatable. It's a delicate balance of pleasure and pain.
Also, to reproduce =)
nobody's disputing your observation. It's yout interpretation that is being scrutinized.Maui said:Yes, i am not particularly fond of arguing with anyone who denies the validity of my obervations or that i exist or that I am able to consciously raise my hand or leg or produce a thought.
If you are not thinking(i.e. there is no one that thinks and makes decisions), what exactly are you doing on a forum that proliferates logic and logical thinking?

Do you observe them different in color?
sganesh88 said:Enough observational evidences? Attributing these awesome abilities of Life to emergent behavior and reductionism just kills the concept of beauty.
Pythagorean said:I never denied that we think. I claim the thinking is a physical process that we experience.
Pythagorean said:If you were willing to watch an experiment about willpower where an fMRI machine is able to predict people's choices before the people have made them based on their neural activity, then maybe you'd actually gain some more understanding of my stance.
But ultimately, An EEG or fMRI won't help you for visually understanding as deep as you'd want too... that's like trying to look at scrambled eggs and tell the yolk from the white. The actual machines are analyzed with statistics with a priori knowledge based on limited knowledge about brain function based on brain damage cases and experiments on animals (and willing human patients).
The brain doesn't nicely compartmentalize in a way that's convenient to understanding it's processing with an EEG alone. You really need to learn the circuits and the functions handled by particular circuits, and there's a lot of them... a really lot. (I'm not claiming to know them, myself, and the scientific community is still establishing them... but they are making progress, they're not dead in the water by any means, you're just not taking advantage of the information that's now available... out of stubbornness!.
In short, "choices" are based on prior information and current situation... basically memory and sensation.
People will always try to make what they think are the best choices for their overall health. The more informed they are, the better choices they can (and WILL) make, as long as they are aware of the significance of the information.
Pythagorean said:Try Neuroscience texts, who's principles are found on physics.
Maui said:My question was about "thinking". Point me to a source from physics that says that properties of matter are responsible for the process of thinking.
