Brain Expansion (Evolution)

dhw: The soul which uses the small brain has the original idea, but the small brain cannot implement the idea, and therefore responds to the soul’s efforts to implement the idea. Similarly, if Einstein had a soul (dualism), or if the thinking section of his brain (materialism) came up with a problem (the initial concept), the effort to solve it may have caused the responses that made his brain different from other people’s.

DAVID: Wow: your finally explained concept is the thinking soul forces enlargement, or with Einstein, the thought effort made his brain very different. Either soul or natural thought recognize the current brain is inadequate and must be improved (enlarged), but only by force of effort.

dhw: I don’t know why you bring in “recognition”, but otherwise you’ve simply tried to rephrase what I wrote in much clearer terms!

Where is "recognition "? My view of your idea is clearer as i stated it

QUOTE "From an evolutionary perspective, the specific parts of Einstein’s prefrontal cortex that appear to be differentially expanded are of interest because recent findings indicate that these same areas increased differentially in size and became neurologically reorganized at microanatomical levels during hominin evolution in association with the emergence of higher cognitive abilities." (David’s bold)

DAVID: […] It all fits my commentary about enlarged brains and the ability for advanced concepts and designs by the brain /soul complex.

dhw: There is no mention of a soul, and the association with higher cognitive abilities fits my own theory just as well as it fits yours […]

DAVID: Another U-turn in your previous thinking. Remember our arguments about the brain as a blank slate. One point we agreed upon was a sizable genetic input. Einstein had a fascinating one based on his early years. See next entry which fully refutes your suppositions about him.

dhw: It was you who insisted on a blank slate, and I objected vehemently because of the “sizable genetic input”. What is the U-turn? Nobody knows whether the materialist’s brain or the dualist’s soul is the source of thought, but whichever is the truth, it makes no difference to the argument that thought can cause changes to the brain! The article tells us all about Einstein’s struggles as a child. Your comment is as irrelevant to the subject of expansion as the article itself:

DAVID: There is no question he was born with a strange brain, contra to your attempts to squeeze him into an example of your unsupported theory of brain expansion. Dyslexia is common and often comes with brilliance. My wife is one, and I've worked a small number of others who fit the point.

dhw: If you think his strange brain was the cause of his brilliance, then please stop pretending to be a dualist.

Why do you constantly ignore my theory which you have recognized in the past. Never pure materialism: The soul always uses the brain it is given, in terms of capacity for new thought or unclear thought as in mental illness. The soul can change the brain only through brain plasticity. The only enlargements we know about are small.

dhw: As far as my theory is concerned, it was you who first raised the subject of Einstein, and you’ve since quoted articles that emphasize several peculiarities in his brain. This can be used as evidence for materialism, but it cannot remove the possibility that his thoughts also caused changes to his brain, as speculated in the quote above, and as illustrated by other examples such as the effort to read, to memorize, to play an instrument.

I resurrected Einstein because his brain is now well studied. It is very different. And you have studiously ignored Einstein's dyslexia and strange childhood educational development, his trouble with early speech, the fact that he thought in pictures as he theorized. His early difficulties mean his brain was different from birth. And certainly learning and theorizing as an adult made some other modifications upon the original different brain.

dhw: I see these examples as support for my theory that the effort to perform new tasks changes the brain and therefore may (it’s a theory) have been the cause of pre-sapiens expansions. There is absolutely nothing in any of your quotes and articles that even deals with the subject, let alone “refutes” my proposal. And I still wait to hear what facts you can come up with in support of your own.

Why ask me for facts to support my theory? You have no support from anywhere. I theorize from facts we know about the brain as you do. I am the one who searches in the literature for information and opinion. Occasionally you've looked. I prefer my analysis of the known facts as containing much clearer logic. It is based on my dualistic approach as above, that the soul can only produce thought to the complexity level that brain allows. Thus each new homo with a larger, more complex brain working with its soul produces new more complex artifacts. All follows along well from thought step to thought step, and it fits Archaeological literature descriptions of what is found and known. As for your incomplete theory, it is simply a wishful extrapolation of tiny expansions in our brain. Have anything else?
