plmkrzy,
I wish science would explain clearly how and why the human mind exists as it does. I dont mean an explanation that just says, It evolved
This is indeed a very good question. As of now, it is the biggest mystery science has of yet to uncover. We know a lot about how the brain works on a technical level. We know pretty well how it stores and processes information. We know how it controls the body and interacts with sense organs.
As is often the case, we don't have a good answer partly because we don't have a good question. What is consciousness? We have defined ourselves as conscious beings. But it is not a well-defined term.
It is closely related to the question of intelligence. For example, playing chess requires intelligence. Or does it? Before machines could play chess, many assumed that if we could teach one to play chess, we would have an intelligent machine. Today the best chess programs can play on grandmaster level. But they sure aren't intelligent, and they don't have a conscious mind. So, obviously, we didn't know what intelligence was. I suspect we still don't.
Alan Turing, one of the founders of information science and one of those who laid the theoretical framework for computers, believed we were basically automata, ie. we were what is called turing machines. A practical test for intelligence is described in the so-called Turing Test. I like this explanation:
"The real point of the TT is that if we had a pen-pal whom we had corresponded with for a lifetime, we would never need to have seen him to infer that he had a mind. So if a machine pen-pal could do the same thing, it would be arbitrary to deny it had a mind just because it was a machine. That's all there is to it! "
We simply define consciousness as something that looks closely like our own mental processes. We don't really know how our own brain processes create what we perceive to be a mind. What are we looking for when we try to explain what consciousness is? We have already agreed we don't know. We suspect we will know what it is when we find it. I think this problem, too, will eventually be solved by science. And I am pretty convinced that those who believe in an immaterial soul component will then find another hole somewhere to put their little soul and their puny god.
