My fundamental premise about the brain is that its workings - what we sometimes call "mind" - are a consequence of its anatomy and physiology, and nothing more.
Although it is difficult to pinpoint the physical base or location of awareness, it is perhaps the most precious thing concealed within our brains. And it is something that the individual alone can feel and experience. Each of us cherishes it highly, yet it is private.
Though the Life Force supplies us with its own purpose, it has no other brains to work with than those it has painfully and imperfectly evolved in our heads.
I have a very serious censorship office inside my head; it censors things that I could tell you that you would never forget, and I don't want to be the person to stick that in your brain.
You can't make a head and brains out of a brass knob with nothing in it. You couldn't do it when your uncle George was living much less when he's dead.
I'm newly widowed, so I've gone from having a life partner, and having another brain to make decisions with, to doing it all on my own and questioning what I'm doing. I have to be a calmer person, because my anger can look pretty terrifying to a young person.
