Evolution and humans: big brain size uses energy (Evolution)

DAVID: There is no implication in my thinking that the big brain is the source of new concepts. It allows them as the person/self/consciousness develops them.

dhw: As before, please explain what you mean by “allows”. […] First: Information. Second: concept. Third: brain expansion in order to implement concept.

DAVID: You have totally forgotten hat I views the brain as a passive computer run by me/soul/ consciousness. The larger size allows the more complex development of thought, concepts, etc., conducted in our enormous cortex, which animals do not have.

I have not forgotten it at all. I asked you to explain what you meant by “allows” and all you have done is repeat “allows”! I can only say again that if the brain is a receiver run by your “soul”, it is you/soul/consciousness that comes up with the more complex thoughts, concepts etc. The larger brain size enables the body to produce the material implementation of the concept. We know that in modern times new concepts cause changes to the brain (rewiring). The logical sequence would therefore be that previously the new concept caused expansion of the brain (until it reached its optimum size), i.e. your God did not expand the brain before humans produced tools; the “soul” produced the concept of the tool, and the need to implement the concept resulted in expansion. (I shan’t repeat my comments about the materialist alternative.)
