Maybe there is a real difference in the brain structure/workings of persons who think gods are real and people who think not. Maybe there is a way to examine the brain of a child to see how it has changed, if at all, when non belief in Santa has become strong. joe [ August 11, 2002: Message edited by: joedad ]</p> |

DRFseven,
You are proposing a difference between the mind and the mind's experience of itself. We feel like we have a soul, but science tells us we are a machine. Therefore the soul must be subject to the machine? I'm not sure your conclusion follows. The mechanism informs the soul, but the soul also can change the mechanism (placebo effect?). In reality, the soul and the mechanism are one and the same. We are only making a semantic differentiation, and I think that is the point of our confusion. I'm not willing to grant a soul, conscious *I*, or any other such ghost really exists separate to the machine. Sure we can talk about a soul, but I do not want to cross the boundary into a real spirit/body dualism. Your conscious *I* is not informed by the state of your body. Rather it is the manifestation of the state of your body. Likewise it could be said that the state of your body is a manifestation of your soul. The glass is half empty or half full. There is no real difference. Quote:

I think you are driving things to an extreme here. There are several options on the table: freedom from causality, self-determination, and external-determination. One extreme removes experience from the equation; the other removes our humanity. In attacking freedom from causality I think you have gone too far in the other direction. I'm supporting the middle ground, where the effects of the external environment and internal processes are mixed. They both have an influence. You could not believe in elves if you had no knowledge of elves. But once the experience is there, nothing stands in the way for you to change your belief. You might not change your belief, but that does not mean you are physically and mentally unable to change. excreationist, Quote:

ManM:
We are destined to do what we do. But we don't observe ourselves walking the path (as DRF7 claims); we walk the path. That puts part of our destiny in our own hands. Though I believe that the activity of our brain is purely a result of physical matter going about its activities... (i.e. no ghosts, etc, involved) I think the conscious part of us just uses information to weigh up our decisions and to set other processes in motion according to hard-wired rules... it is like a central executive and it relies on advisors to do all the research for it including getting them to work out how desirable (+ or -) the options or stimuli are. As I said before, we are not free of our self-determination. What do you mean? Do you mean that we truly have free will? That being said, I hesitate to agree that our choices were inevitable given the initial conditions for the reasons which Jobar pointed out. Yeah... I guess I was assuming deterministic-type physics there... but I think physics is still fairly deterministic on a larger scale (e.g. on the scale of neurons). I don't know much about quantum physics but I think it might partly work a bit like a dice being thrown or a coin being tossed... on a small scale, it is highly unpredictable, but on a large scale, a pattern tends to emerge. e.g. about 50% of coin tosses come up heads - although it is (theoretically) *possible* that you could toss a coin a million times and always come up tails. It would be a 1 in 2^1,000,000 chance though. In a Newtonian universe, coin-tossing would actually be deterministic, but appear to us to be random... and that's what the field of "chaos theory" is about I think... somewhat complex systems that appear unpredictable or random to humans although they are based on deterministic maths... Jobar's post, from page 4(?): Quote:
Given a few physics experiments, determinism isn't the fad among scientists anymore. The brain would still be fairly deterministic on a minute-to-minute neuronal level... quantum physics-type random would affect the future external environment but it wouldn't affect our neurons in big ways very often... anyway my point was that I think our consciousness, memories and intelligence rely solely on physical processes and systems. You were saying that this means that it was therefore deterministic. I was just assuming you were right. If we aren't deterministic then we are partly at the mercy of random quantum fluctuations. But all in all, I think we are in somewhat of an agreement on this matter. I thought you believed in true free-will and spiritual things like ghosts/God, etc... also, in the central executive idea, "we" do practically nothing except oversee everything so that we can make very straightforward decisions that have been virtually spelt out to us by our advisors. "We" would oversee our working memory, which is a pool of short-term memory that is all together so that different things can be associated with each other... e.g. the sound "red" can be associated with the colour sensation... the written word "red" can be associated with both the sound "red" and the colour sensation, etc. |

I read a book about the nature of time once and I remember a vivid description of the author's suggestion on how to picture the human in time. In this model, the human is like an extrusion of Play-Doh out of a cosmic Fun Factory, almost invisible on one end, getting gradually bigger as the individual reaches adult-size, then changing shape and abruptly getting small and dissolving into invisibility again. At any "now" point, a cross-section would reveal the human "now." This model doesn't depict attitudes and behavior, but, if you could see them, they'd be in the cross-sections of "now", too. If the attitudes had a shape, there would be some coherence to it, but it still would be constantly shape-shifting; it would never remain motionless. |

I am going to put this as clearly and concisely as I can in hopes of resolving this debate.
1) We are determined by experience. 2) We generate some of that experience ourselves. 3) It follows that we play a part in our determination. We all agree on #1. Biology and neural network theory supports #2. That leaves us with #3. DRFseven, you obviously don't like #2. The mechanism may generate its own experience, but we are not the mechanism? We are a soul that is a slave to the mechanism? When someone believes in the primacy of the soul they are immediately challenged by the fact that mind altering drugs work. Likewise, you are challenged by the fact that faith works (talking cure, placebo effect). Both of these interactions are explained quite well by the idea that our body and soul are not two different things. You are going to have a hard time convincing me that #2 is wrong. Excreationist, I don't think you have written anything which contradicts #1 or #2, and so you might have to acknowledge #3. Now we may disagree about God and other things, but I think we have the common ground to resolve this debate. I do not believe that we have a supernatural component. If we conclude that #3 is the case, the elves lose their punch. |

Do you think that our attitudes from which our choices are determined are reached through experience? Is motivation achieved through experience as well? [ August 14, 2002: Message edited by: DRFseven ]</p> |
