First of all let us be clear about some concepts, as I think you misunderstood non-extended matter in relation to concepts such as gravity. Non-extended matter is the type of objectivity that cannot be touched, whereas you can touch matter, or concepts such as objects and brain. First let us confine ourselved to the interaction of gravity and objects. Let us suppose that we have two objects at hand, one alot more dense and massive than another one. According to the laws of physics, the smaller, less dense object will be under the influece of the larger object because of gravity.
No. They both attract each other according to F = Gm1m2)/r^2
There is only once force. And it doesn't matter if one object is 100 kilogramme and the other 1 or both are 10.
Then in what sense this force causes acceleration has to do with inertia. Massive objects are harder to put into motion: F = ma. So same F, big m means smaller a.
You can touch the two objects, but you cannot touch gravity. This is what I meant by non-extended matter.
Gravity is not matter. It's either a force caused by gravitons, which would be matter and would be touchable. Or gravity is the curvature of space-time which is caused my mass.
Similarly, this applies to the concepts of mind and brain. The brain influences the mind, and you can touch they brain, whereas you cannot touch the mind.
You can't touch the mind because it is an immaterial concept. You can touch the brain.
Just as with the interaction between objects, you can know of gravity, but you cannot touch it. With the concept of mind, you know that the physical brain emotes the mind, but you cannot still touch the mind.
In the case of gravity you can touch the matter that causes it and you can observe the curve in space-time it represents.
You can't observe the mind independent of the brain. Because while gravity is independent of matter, the mind is just not independent of the brain.
Non-extended and extended matter aren't really forms of matter, but more of concepts of existing concepts of matter, with the non-extended denoting the matter you cannot "touch," but can obseve, and extended matter being the matter you can "touch" and still observe.
If it isn't matter then don't call it matter. Silly Descartes...
So how can you observe the mind? When we do that we are really observing the brain. I don't know of a way of observing the mind without looking at the brain. I do know tons of way of observing gravity without observing the matter. That's how we first discovered black holes, for example. And that is also how we try to find planets around stars far away. We look for the curvature in space-time they cause.
This is the question, how cannon-observable matter interact with observable objects. We know that gravity, is no less "real" than mind is, impacts objects, so why shouldn't the mind affect the brain?
Now you do call it non-observable. By definition the non-observable can't interact with the observable because if the interaction has effect on the observable we can see that effect, and thus see the interaction and thus observe that what is supposed to be non-observable.
You are making contrary points which I never provoked. When did I ever assume that it is the mind that governs your bodily actions against the predetermined nature of a particular physiology? I am merely contemplating the possibility that mind isn't dependanton physiology.
Gravity is totally dependent on matter as far as we can tell.
Lets take this a step back. We all know that our bodily actions are governed by the brain. We also know that the brain is capable of producing a hypothetical concept such as the mind. We do not know whether or not the mind has the potential to govern itself. I never made the suggestion that your mind governs you actions, I am making a point that perhaps mind has the potential to act on the brain, which in turn will decide your actions.
Again, I don't see how the mind, which is the effect of the brain, can influence that what it its cause.
You are making points which I did not provoke. When did I ever say the brain cannot explain the mind.
Then why not quit this discussion immediately then? If there is nothing the supernatural mind can explain which the physiological brain cannot then the concept is totally useless.
I do imply that the brain, just as the physical object I talked about earlier, has the potential to produce non physical entities, such as the mind. The physical objects are physically existent, or "touchable," whether the mind is not, but just as gravity, is present.
But the mind is immaterial. The mind is the immaterial result of the purely material processes that go on inside the brain.
I never suggested that the mind can definately control itself. I am contemplating on possibilities. Also I never suggested that the soul is in any way in authority of anything.
Isn't that the same thing? You are all free to do so, of course. But why would you contemplate something if you don't want to suggest it.
It is much easier to refute anything rather than to confront it.
Because here 'anything' and 'it' are not defined this sentence is meaningless.
It is much easier to say that the mind doesn't exist because it cannot be observed rather than to investigate it.
You can only say that the mind cannot be observed if you tried to do so, which means investigating it.
My memories, my thoughts, etc. They aren't made of matter or energy. They are coded for in my brain through neurons. I have 100 billion neurons and they store information by making patters and connections. Every neuron connects with 1000 to 100,000 other neurons, making a total of 1x10^14 to 1x10^17 connections. These connections store information. They determine the nature of the mind.
Just as you can build a neural net artificial computer. You can have it run simple algorithms to recognize pictures or faces. These processes do exist, but they aren't made of matter or energy themselves.
And in our normal computers information is coded in bits using magnetically charged fields and the lack of them.
Bits aren't made of matter or energy either. So in a sense they are 'non-extended'. But they are the effect of normal matter.
A mind that isn't capable of influecing the body, such as the mind you seem to propagate, would not be able to assume points that are alien to it, namely, the non-physical entities such as the soul and God.
A mind that isn't a mind wouldn't be able to contemplate concepts like a soul or a god, yes.
When a mind conceives of notions that aren't grounded in reality, it suggests not that the mind itself is somehow a creation of the supernatural, but that the mind can assume the supernatural. This wouldn't be possible for a mind that wasn't existent, because a non-existent mind is under the control of the brain, which accordingly, could not assume anything supernatural.
A mind that does not exist does not do things that a mind can do. Of course our mind can conceive of all kinds of ideas. If they are grounded in reality or not does not matter. But it is hard to know if our concepts are grounded in reality or not. Therefore we use scientific method.
The notion of soul is only acceptable to a mind that isn't bound totally to the brain. I never suggested that that proves the validity of supernatural however.
Well, here you say that the brain limits the mind and that a soul is needed to explain what the mind can do what the brain can't explain.
If a brain can perfectly produce a mind that can conceive of the supernatural. Conceiving of supernatural concepts is physiologically no different that conceiving of any other concept.
