The Evolution of Symbols in the Brain

inexperson ideas are all information in a mind that can affect the mind, but is not expressed in any kind of language. How is it even possible that there could be inexperson ideas? I don't think that the brain has a language in that sense. But there is logic in the brain at an emergent level, but at a lower level there's just physics. There's just biology. And if you were studying all that with a microscope and a supercomputer to analyze it, you'd have to go quite deep into the analysis before you could see that the human mind is using symbols abstractly to represent things.
