The function of the brain and nervous system is to protect us from being overwhelmed and confused by this mass of largely useless and irrelevant knowledge, by shutting out most of what we should otherwise perceive or remember at any moment , and leaving only that very small and special selection which is likely to be practically useful.
According to such a theory, each one of us is potentially Mind at Large.
