That doesn't mean anything. The laws of physics are the rules. That's why I say it's circular reasoning. I ask you what is a rule, and you say it's at the bottom of laws, but laws are just another word for rule. There is no bottom, because there's nothing there. It's an intellectual construct. > How they are enforced is > not directly relevant to this discussion (although it is something > discussed on this list in the past) To me this clearly means "Pay no attention to the man behind the curtain." > we just need to know that things > fall down rather than up, and that the force on them is proportional > to their mass and inversely proportional to the distance between them > and the centre of the Earth. No, that's just what you need to know. I need to know what up and down are, what's a force made of, what is proportionality and inverseness made of and where does it come from. I think that my model provides a sound basis from which to examine those questions scientifically. All of those questions that 'we' don't need to know the answers to. > If you believe that such laws are due to > the Earth having a certain basic consciousness there is no evidence > for this, but even if it's true it doesn't change the argument, which > is that the behaviour of the brain and every other object in the > universe can in theory be predicted if the simple rules are > understood. So the behavior of the Taj Mahal's construction can be predicted if the simple rules of bricklaying are understood. Wherever there are bricks there will be Taj Mahals eventually?? Not compelling intuitively. No evidence.

What predicts whether the apple will be someone's favorite fruit? You're just avoiding the question of what complexity actually is and spiraling off into repeating the same 19th century bunk materialism argument that 1+1 must = rich Corinthian leather sooner or later. >It makes no difference if the apples or > the system of apples are conscious: they still do exactly what the > physical laws say they should do. There are no actual physical laws. There are only our observations of the patterns we can observe which share physical characteristics. The idea of 'laws' is a way to understand how the universe makes sense, but there aren't ghostly metaphysical police departments making sure that matter does one thing and not another. If we only pay attention to physical phenomena, then we have nothing to say about subjectivity. Physics doesn't predict comedy or tragedy. That doesn't mean that comedy and tragedy are illusions or magic. It just means they are a different kind of phenomena than a billiard ball or many many billiard balls. > There is no downward influence from > the system on the apples, for that would appear as magic, and we don't > see apples behaving magically. If we had never seen an apple tree grow out of the ground from a seed, then it would be indistinguishable from magic as far as any physical computation would anticipate. There is downward influence on everything. The planet affects weather, weather affects crops, crops affect our diet, diet affects civilization, civilization affects domestication, domestication affects our diet and health, health effects our consciousness, consciousness effects what we decide to eat, etc etc. Each link contributes upward and downward influence. The further the influence is from our perceptual-relativistic niche, the more is seems deterministic and mathematical. The closer it is to our native subjective frame of reference, the more we perceive it to be natural, living, familiar, and finally...us. > > >> If you are non-deterministic, > >> then nothing determines what you do and you are a slave to the roll of a > >> die. > > > Only if you a priori eliminate the possibility of free will and sense. > > Then you are left with the options that make no sense and have no free > > will. > > If it isn't deterministic, it's random.

Oh, well if you put it scientifically like that... As long as we're at it, can we state that arguments from authority are the basis of scientific curiosity?

What if your decisions are based upon your own choices which arise out of experience, randomness, and actual, legitimate, personal volition.

However in order to 'notice' anything, you have to have awareness of some kind to begin with. Consciousness is an awareness of awareness. Awareness itself has to have the property of being able to feed back on itself. A ping pong ball does not have that property, nor do a trillion ping pong balls in a giant box. > > > Why is that 'simply'? How do you get 'pieces' to 'interact' and obey > > 'rules'?

The brain as a whole is made of a zillion micro physical effects. The experience of a person as a whole is made of a zillion sensorimotive micro experiences. They do not correlate one to one, a thought to a neuron firing or a neurotransmitter molecule to a feeling, but are instead complementary expressions of the overall phenomena. Like a pattern of pits on a CD and a song correlate to a common sense, the pits themselves are not translatable into a song without a living human psyche to listen to it being played on a CD player. > > >> Craig, can you tell me if you disagree with the following description of > >> physical supervience: > > >> "To give a somewhat simplified example, if psychological properties > >> supervene on physical properties, then any two persons who are physically > >> indistinguishable must also be psychologically indistinguishable; or > >> equivalently, any two persons who are psychologically different (e.g., > >> having different thoughts), must be physically different as well. > >> Importantly, the reverse does not follow (supervenience is not symmetric): > >> even if being the same physically implies being the same psychologically, > >> two persons can be the same psychologically yet different physically: that > >> is, psychological properties can be multiply > >> realized<http://en.wikipedia.org/wiki/Multiple_realizability>in > >> physical properties." > > > Yes because it assumes that there is a such thing as two persons who > > are physically or mentally indistinguishable.

That would be true if I were an idiot and had not considered that already many times. I get what you're saying. You don't understand what I'm saying.

Then that means it's no worse either? It makes a difference because the functionalist position is a wild goose chase for the Philosopher's Stone of a formula for exporting our consciousness into inanimate objects.

I don't know why you keep wanting to hear the same objection over and over, but what you're saying is completely bogus. It's no different from saying that if understanding how a TV set works doesn't predict the winner of the Super Bowl ten years in advance, then there must be magic occurring. > > >> > This view of the psyche as being the inevitable result of sheer > >> > biochemical momentum is not even remotely plausible to me. > > >> Why? > > > Because it doesn't take into account that there is an experience > > associated with the psyche which is dynamically changing the > > biological momentum from the top down from moment to moment. > > But there is no evidence for this over decades of meticulous > biological research. Are you saying there is no evidence that we can manipulate our own brain chemistry consciously? Since emotions are essentially (but not existentially) the same thing as physical events in the brain, if you assume that the physical events are primary, then your study will reflect that. When a person decides to think about something that is associated with a certain emotion, neurotransmitter events takes place in the brain (in different regions, some simulataneously, some in chain reactions). There is no evidence to suggest that the neurotransmitters in the patients brain could cause the doctors brain to suggest to the patient that they think of something which would precipitate that brain event or emotion. We are not just biochemical puppets. Our biochemistry responds to our feelings and thoughts as well as causing us to respond to it's collective experiences and conditions. I don't see how you can deny that with any sincerity. > > >> If the atoms always follow these laws, and we can come to know these laws, > >> then in principle a computer programmed to follow these laws can tell us > >> how > >> a particular arrangement of atoms will evolve over time.

If they did, we would be able to predict their behaviour. No. That's what you're saying. I'm saying that physical laws are observations about simple, literal, objective phenomena. Not everything can be addressed meaningfully by the laws of physics. It's not a universal tool of understanding, it has a specific, limited efficacy. If we understand what physicality actually is, and what makes it possible to even consider the idea of anything other than physicality, then we could realize that predictibility is one of the qualities which diminishes the more you look at the other end of the continuum of sense. Matter acts predictably on the outside, less so on the inside. > > >> But you said earlier that no violations of physics occur.

We know too much about what's going on from the inside view to be able to predict to any meaningful degree of precision. We can predict generally how a healthy brain should function, but not the idiosyncratic patterns of how any particular person's brain will function over time. If you could predict how the person's life will go minute by minute, then sure, you could get a pretty good idea, but then you have to predict the entire universe. > > >> Our model of how electrons behave and interact has predicted the anomalous > >> magnetic dipole moment of the electron and the prediction agrees with > >> empirical measurement to 10 significant figures. > > > That very success is part of the problem.

If you want to predict the trajectory of a serotonin molecule in a brain, you might need to know what a person is thinking about. Serotonin in a brain acts differently than serotonin by itself in a vacuum. There is nothing in the molecular structure of serotonin which indicates that it should have a role in something like a human brain. What is meaningful about serotonin cannot be described in purely in terms of it being a bonded group of atoms. It's a physical agent but it's also a chemical, biological, and neurological agent. > > You can't have it both ways.
