What do you guys believe is the difference between the brain and the mind? Is there nothing additional that distinguishes the mind from the brain; something “immaterial” that could be considered “spiritual”? And if there is something spiritual that forms a composite to create the mind, what is its function?
I find neurobiology a fascinating subject. I have just completed my fifth Coursera Course given by top-notch professors from leading universities and what I have learned in my yearlong study is that the scientists have done a magnificent job in generating the in depth and detailed knowledge of the human brain. Not a single one mentioned “consciousness”.
Your bios (Catholic, Baptist) imply a belief in God. Which raises a question in my mind (not my brain): why don’t you believe the spiritual substance that is associated with the soul does take part in the activity of the mind, that the immaterial phenomena such as thought, qualia, feelings, emotions etc. are produced by the spiritual memory and are not just an “emergent” property of the neurons in the brain?
However I do understand how persons that are enamored with science can fall into the trap of believing that science is the only approach to the search for the truth of reality. Let me demonstrate with an excerpt from a lecture by a very brilliant professor that knows the entire central nervous system (CNS) in minute detail and can describe the function of each and every element.
Now, recall that the somatotopy in the motor cortex is a gross reflection of the somatotopy that we find in the somatic sensory cortex, across the central sulcus and the post central gyrus. But the detail is quite different. Rather than there being a faithful representation in a point-by-point fashion of the contralateral body surface, what we see in the motor cortex is a map of movement intention. And that intention is roughly somatotopically organized in the following way. With movements that we intend to make involving our lower extremity being represented here in the paracentral lobule on the medial face of the hemisphere, and just out a bit into the dorsal medial margin of the hemisphere. Well, as we progress in a lateral and inferior direction, we move from the lower extremity up through the trunk and into a large expansive region near the center of the motor cortex that is concerned with the movements that we intend to make with our arms and our hands.
(The one thing I learned from these courses is that I have gone from an A to a C student. I still comprehend but don’t retain very well.)
The reaction to such a presentation is usually, "Wow! this guy really knows his stuff!’. It is natural to be easily impressed by such deep knowledge and tend to rely on such people for our general knowledge even that which goes beyond the area of their expertise. However, if one reads philosophically, i.e., with discernment, he/she might just ask the most important question that this excerpt raises, namely, what is the “map of movement intention” and what and where is it? Does a neuronal object decide when to move the arm? Then we might also ask, "what is the WE in the phrase “we intend”? Is WE a neuronal circuit? I think you know the answer and the WE or the I isn’t one or any number of neutrons.
There is a great tendency for neurobiologists to bury the real questions in a stream of magnificent knowledge using inexplicable words or phrases.
