Yes it can and once again science shows it. Percpetions come from the brain. The mind comes from the brain. Consciousness cannot exist independently from the brain. Why is this so hard to understand?

You claim alot, why should I believe you? Do you even have any evidence to support these assertions?

Kielicious,
What does it mean for someone to travel into the future? Nothing. I'm familiar with the theory of relativity, it isn't relevant to this discussion. By my definition, the future is 'that which has yet to happen.' Therefore, by definition, one cannot travel into the future, as that would entail experiencing what has yet to be experienced. That is NONSENSE in the strictest, non-derogatory sense of the word.

How does a brain create perceptions? How does a material thing give rise to an immaterial thing? Short answer; it dosen't, there are no things, only mental constructions.

Scientific research indicates that certain brain functions relate to certain mental functions. They cannot explain the mechanism though, and not because they havn't done enough research. It is an impossibility. It makes no sense at all. Material things do not afffect immaterial things.

@BrightNoon,
BrightNoon, Thank you for elaborating. If I might comment. You following statement...
....
"It all comes down to one thing. You never live in or experience anything but the present. So what do we mean when we talk about the past or the future? When we say 'the tree fell down yesterday' or picture that situation, are we experiencing that tree falling down? No. We are experiencing at that moment an idea, which happens to be that of 'tree falling down."

Perhaps it is the words you are using that is confusing me. The "tree falling down is not "an idea", IMO, it is an "event" that either happened or it didn't. I don't consider it an "idea". If in fact we did experience the tree fall, it just is. Period. We are not "experiencing that moment" we are remembering it. On the other had if another said a tree fell down. what you espouse has merit and then we create the illusion of a tree falling based on what that means to us. It virtually means "nothing". If it is a witnessed fact, it can be trusted and relied upon, whether it is useful is another question. If one had never experienced a tree falling down then the "imagination" comes into play. And yes they are all manifested in the fleeting present or the now which is truly all there is. The past is extremely important to the now if we can extract the "truth" from it.

Using the words "idea and illusion" is what is throwing me as I am efforting to determine what you are trying establish. I do agree we are the sum total of what is in our mind. The only thing that can be truly relied upon is what we personally experienced. That is our truth. Anything else is an illusion and whether it can be trusted is a toss up. Are there any other words you could have used other than "idea or illusion"?

... before you two guys who enjoy a good fight really start scrapping it out, let me interject one thing: scientific research grounded in Aristotelian substance and Cartesian dualism consistently runs into this problem, whereas scientific research grounded in process metaphysics and embodied cognition is making strides ...

You said the future doesnt exist and yet I should you it does.... Do I need to connect the dots for you? Geez.

Clearly you have been reading too much Descartes.

Ill ask you some trivial questions:

If the brain and consciousness arent related then why does damage to your brain cause damage to your consciousness?

If I hit you in the head and knock you unconscious how can that be if the mind and brain are seperate?

Why does stimulating certain parts of the brain effect your mind, your sensations, your percpetions?

Why do drugs effect your perceptions if its all biochemical interactions?

....Im quite sure you havent taken one psychology or neuroscience course have you?

Let's consider this example. Bob and his 100 million friends are sitting in a big room. Everyone in the room except bob believes that the walls, floor and ceiling are painted white. Bob believes that the walls, floor and ceiling are made of French toast. I believe you are suggesting that Bob's experience is wrong because it disagrees with what is considered a sufficient number of other experiences. Here is what I'm saying. If Bob's experience can be wrong when he thinks its right, why couldn't the 100 million other experiences be wrong? There is no standard by which to judge any experience and a statistical generalization is not necessarily accurate. If the majority of people were in error, it would be less accurate.

There is no distinction between this and the example with lead. Per your logic, that the sum of all perspectives must reflect a more accurate picture of reality than any one perspective, a population convinced that lead floats would be correct. The lone man who thought otherwise would be incorrect.

This is an assumption, which is fine if you acknowledge it as such. No one observed those events. They exist only in the minds of people who think about things like this (that is all we know for sure; those events could have happened, but we do not know).


[quote]... agreed - but do physical things have to have meaning assigned to them before they can happen? ...[/quote]

Until meaning is assigned to them, they do not exist. What do we refer to when we say 'they': a meaningless event that cannot be understood in terms of anything we have ever experienced? If so, then we are talking about nothing. If not, then the 'thing happening' is dependent on the thing having meaning, which can only be given it by us.

Yes, I agree.

This is an assumption. The universe appears to disappear. We can not know whether it remains or not. Fact; we have sensation. Assumptions; when we have a sensation, we are sensing something, Or, there is more to a sensation than the sensation itself.

@Kielicious,
(1) You have not demonstrated that the future exists; you have said that the future exists.

(2) What does it mean for an cosmonaut to travel into the future? Could he tell me who will win the lottery if he stayed in orbit long enough? Did the cosmonaut experience something which had not yet happened? Relativity deals with 'time travel' as a issue of perspective, not cartoon style time travel. If the experience of time is relative to one's perspective (velocity for example), there is no absolute Time through which one could travel. Rather, people just experience their own experiences (or could if travelling fast enough) at different rates. Bringing this back to earth; that experience is still present experience. No one could experience their own future; that is NONSENSE, once again. By NONSENSE, I mean that that statement has no meaning. It is like this; 'the dog is waved yellow'. That has a subject and a verb, but it dosen't mean anything.

(3) If you are to claim that A causes B, you have to know how A causes B. More importantly, there has to be the possibility of A causing B. Science asserts that every effect has a cause. Science only deals in physical things. Equations and quantitative analyses are innaplicable to the feeling of warmth, e.g. Science can only deal in molecules, atoms, photons, electrons, etc.

You assert that the cause of consciousness is the physical brain. I ask you to explain how this might occur even hypothetically, using empirical science. In other words, explain the causation with reference only to physical objects. O, you can't? That is because the last item on the would-be causal chain is not a physical thing. Science only accounts for physical things.

(4) If you think I have read too much Descartes, you have read too little. I'm not advocating cartesian dualism. I am opposing the purely physical/objective/empiric world-view with a purely subjective/individual/existential world-view.

What do you mean by intersubjective? Until we figure that out, I'll assume you mean objective (the sum of many subjective views). The objective view is only acccurate within the objective view; but what is the objective view? No people have an objective view. It is an abstraction. Life as lived is not objective and there is no reason to assume that life as lived is 'incorrect.' You might say that the objective view can predict or explain something missed in real experience, but I would say that those predictions or explanations only appear accurate on reflection. In the present, there is no doubt that experience is accurate.

Sure, without humans those experiences would continue, but there would be no beings with memory, and thus, no past, and no beings with deliberative capabilities so the future is nothing other than a probability of possibilities. Natural phenomena are nothing more than cause and effect, and it takes observation to put them within a relative time frame. Memory is a required feature to have a past. Now if a different being developed these two features then the past and future manifest into a real concept.

That is a different type of memory. Dogs lack the necessary abilities to have a conceptual memory over time.

@BrightNoon,
I have to agree with P.H. here; dogs have memory of some kind and could experience the illusion of time like the rest of us, albeit to a lesser degree (I guess...never chatted with a dog). This brings up an interesting point. I was reading the thread about 'organized intelligence'...forget thwre that was. Anyway, very interesting stuff. I've been waiting to post until I can get my thoughts together on the subject. If dogs have memory, do frogs, do worms, do bacteria, do crystilline rocks, etc? I tend to think so, but there is no way to really appreciate the nature of that kind of 'memory.' As I think memory/thought is a function of reaction, I have to assume that anything which reacts, which would appear to be everything to some extent, remembers/thinks.

Thoughts?

That is pretty much the difference between conceptual memory and contextual memory. I would say that the former requires rationality and the latter has more to do with instinct.

I think contextual memory is developed through experience with cause and effect. Fire is hot type of stuff. On the other hand conceptual memory has to do with being able to organize memories and give them structure. History is a form of conceptual memory.

@Theaetetus,
I agree T. Would contextual memory exist in bacteria? They do not think 'fire is hot', but then again when we touch the stove, I doubt we have the idea 'fire is hot', we just react...and perhaps think of 'fire is hot' later. In the same way, bacteria react and can 'learn.'
