Consciousness, "I", a "person". Mahendra Gonsalkorale

Consciousness, "I", a "person". Mahendra Gonsalkorale

I do believe that we cannot be ourselves with our store of memories, attitudes, beliefs, fears, apprehensions, exhilarations, sadness, happiness, relationships, puzzlement, amazement, confusion, wonderment, and a whole host of other things without our physical Brain. Not having a properly functioning physical brain is like having a computer without its processor and memory. I, therefore, believe that the physical brain is a sine qua non for consciousness and self-awareness. 

I base this on our knowledge of how we change when parts of our brain are damaged by injury or disease. The range of effects seen are enormous and dependent on which areas are affected. It can be just a loss of memory of varying degrees to a total change of personality so that the person "now" is totally different from the person "then". But both are conscious in the sense that they are alive and aware with all the bodily functions, responds to questions and exhibit behaviours. They sleep, they wake up, they laugh, they cry, they show happiness and sadness but they could be totally different although the physical likeness is preserved. We, therefore, have a body in which there appears to be now a virtually totally different person. We see this in frontal, fronto-temporal and hippocampal damage for example. Or take a disease like Alzheimer's which can be so devastating in change of personality. To me, this means that our brains when functioning as a whole organ give us a sense of being a "person" and the notion or person is conditioned by what is stored in our brains and what is produced in the brain by the various neuronal circuits interacting with each other. In this case, the sum is greater than the addition of individual parts. A symphony is a collection of music on different instruments but the effect it produces is above and beyond its parts. There is absolutely no evidence that the person who "was" before the cerebral insult is lurking somewhere within him trapped in a physical form beyond his control. If this is the case, this sad person has a "hidden original me" with a "new me" that arose within the same body after the damage. I don't think that is possible. 

But slightly digressing, our concept of being a person is so dependent on what goes on in our brains at any one time that even a "person" can be different "persons" at different times depending on situations, time etc. In a way, there is no "person" as such but a succession of experiences of being a person. We think we are the same because the change is gradual and occurs within a physical body we can see and feel. but we need to only take our minds back a few years and find that in many ways, we are now different, and in some cases, massively so.

So to sum it up, our functioning brain continuously informs us that there is an "I" (consciousness, awareness) and this I believe functions even when we are asleep but as sleep shuts us off from experiencing impulses from our "outer senses" (such as vision, touch, smell, hearing), we are not aware or "conscious" as in the wakeful state but we are there, and our brains are working producing all sorts of activity which can even result in playback of a "video" constructed from true past life experiences and totally "computer generated" images of things which never really happened and we call this dreaming.

"I" arises from brain activity giving us a self-awareness. No brain - no self-awareness -no consciousness!

Just to complicate matters, if we blow up any living being through a zoom with massive capability, you will just see at first a collection of cells and then as you zoom further you will see  molecules -->  atoms --> fundamental particles --> wave forms and within all this, as much as 90% is empty space!

I hope my article will stimulate an useful and interesting discussion. I have purposely kept Religion away from it although this may have resulted in an incomplete view.
