I&#x27;d love to have some evidence that such things as &#x27;concepts&#x27; and &#x27;ideas&#x27; can exist independent of brains. You can&#x27;t just assert it and make it so. All concepts and ideas I&#x27;ve ever heard of were the results of brains attempting to model or describe.<p>By the way, I&#x27;m not talking about physical human brains. I&#x27;m talking about <i>any</i> brain, which includes human brains, dolphin brains, computers, and whatever other modeling machines exist in the universe.
