The neurochemistry of the brain is astonishingly busy, the circuitry of a machine more wonderful than any devised by humans. But there is no evidence that its functioning is due to anything more than the 10(14) neural connections that build an elegant architecture of consciousness.
The more one listens to ordinary conversations the more apparent it becomes that the reasoning faculties of the brain take little part in the direction of the vocal organs.
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.
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.
Antidepressants are very good, but it's a clinical cosh, really. Sometimes you have to be knocked out, just to stop; when you're in that state all you want to do is just sleep, and rest your body and your brain.
The mind is a finer body, and resumes its functions of feeding, digesting, absorbing, excluding, and generating, in a new and ethereal element. Here, in the brain, is all the process of alimentation repeated, in the acquiring, comparing, digesting, and assimilating of experience. Here again is the mystery of generation repeated.
Alas! they had been friends in youth;
But whispering tongues can poison truth,
And constancy lives in realms above;
And life is thorny, and youth is vain;
And to be wroth with one we love
Doth work like madness in the brain.
