Alpha you're out of your tree!!
I argue because, those that are speaking as if certain in this matter, are speaking as if they "KNOW" how the brain works. If scientists currently admit they don't know how it works, then who are PNF frequenters to state that they know certainly how it works.
Since they do not know the following they cannot speak with certainty:
(1) What consciousness is.
(2) What ever it is, how it works.
(3) What thinking is.
(4) What ever thinking is, how it works.
(5) How are thoughts created.
(6) Where are thoughts created?
(7) How much time is required to make a thought, certainly pathways between neurons (new data) aren't created instantaneously.
(8) Which is more proper, speaking of the unconscious, or subconscious mind, remember that some philosophers argue that it doesn't exist?
(9) I could come up with many, many others...
Those that say they don't have to know such things, for them to say what's already been said in this thread with certainty, have a problem with their thinking. Have a problem with their denial getting in the way. It would surely seem they don't want to be responsible, for somethings that they've already done. This can be used as a means to both sidestep learning and responsibility, to perpetuate the problem. To continue doing something because they actually like it. Manic??
Here you go:
What's in this box I'm holding? Tell me with certainty!
With respect to what's in this box, how does it interact with that which is outside the box? Tell me with certainty!
If a long time ago, I told you what was inside the box, and how it interacted with that which was outside the box, upon asking you now, the first thing that would come to your mind, might be what you were told was the truth then, in that case, which might bias your 'guess' as to this current case, but in fact you could not know as if certain. First, I could have been lying the first time. Second, I could have changed it's contents. So in truth you could not speak as if certain, you could only ever speculate. Which is exactly what is being done in this particular case with consciousness.
Because you have a mind, and the old ideas seem to fit that which you experience, which is why they were posited in the first place, you 'believe' in them, they certainly 'seem' the case. But just because they 'seem' so, does not mean they 'are so, certainly, in 'truth!' Which in fact is what the scientists are currently attempting to ascertain.
Of course you guys want to beat your chests, playing the part of scientists, and speak with certainty! But the truth is, that you can't!
