Thanks. So to re-iterate, what you're trying to establish is that it is possible for the brain and mind to be two separate entities; there's no logical contradiction.
Well, I'm not sure if I agree with you, though it's hard for me to say that something like that is impossible. You may be right. I think what many people are trying to say here is not so much that it is impossible, but that it is unnecessary. It's simpler just to say that the mind is a property of the brain, and fits with what we know scientifically about the brain. So since it's simpler, it's more logical to go with that. I think that's where I'm coming from, too.
Now that I know where you're coming from, let me point something out and get your thoughts. Isn't it possible that there is a logical contradiction, and you're just not aware of it? Perhaps the reason you are not aware is because we don't fully understand yet how the mind is a property of the brain... there is definitely evidence that it is, but we don't know all the details yet. If we knew all the details, isn't is possible that we would say that the mind is a property of a brain in exactly the same way that round is a property of an orange?
In other words, when you say "we can conceive of a mind without a brain," is it possible that the way you want to conceive it is itself fundamentally flawed?
Hi there.
First, I do agree that there can be a logical contradiction, and a one that I am not aware of. But I don't think that it can be discovered by making more scientific expirements.
I think so because what scientific expirements establish is exactly that B is caused by A. They make a change in B, and observe a change in A. They do it a lot, and conclude that B as a whole is caused by A. I don't see any logical pathway that leads from "B is caused by A" to "B is a property of A".
(B=mind, A=brain).
I will give you another example that is not intended to prove that the mind is a cause of the brain (vs. a property of), but merely to sharpen your intuition about it.
Suppose that there is a Third variable, that the brain causes it, and this variable causes the mind in its turn. (We think that A causes B, but actually A causes C, and C causes B). I don't know what that can be, and do not say that this is the case. But it could logically be true. And in this hypothetic scenario, eliminating C from the equation would stop the relationship between A and B. A would no longer cause B, the brain would no longer cause the brain.
Or alternatively, the third variable is the brain causes the mind, only in the presence of this variable. A causes B ONLY in the presence of C. Nevermind what C is. Eliminating C, again would prohibit A from causing B, though for a different reason.
Now why do I care about these examples? I don't think that they prove anything convincingly, but they illuminate by showing that these examples are possible that relationship between A and B is a causal one. In a relationship between a thing and its entity, one wouldn't expect these options, as far as I can think. In a relationship between a thing and its cause, one would. These examples just illuminate and sharpen the case, I don't think they are strong enough to prove.
How can I be convinced that there is a logical contradiction actually? JoeThe Juggler argued, and I am convinced by this specific point that the popular understanding of the "soul" involves some type of "ghost-body". So there is a contradiction in it. On one hand it claims something immmaterial, on the other hand there is a ghost-body. (The fact that the ghost-body is transparent still doesn't make it immaterial... ). And I agree that the popular idea isn't really conceiving a disembodied consciousness. So this type of argumentation I can accept, and I think is useful.
