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

DAVID: I'll again ask, shouldn't you note that my scenario fits the facts as much as you think yours does? Also most of our giant pre-frontal cortex arrived long before we figured out how to be civilized and develop all the non-material concepts now present in the arts and sciences. It is still obviously size first use second.

dhw: The second point we have been over again and again is that your insistence on size before use (during the times before complexification took over), with its implication that the brain is the SOURCE of new concepts, runs counter to your dualistic belief that the brain is only a RECEIVER of ideas thought up by the “soul”.

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.
