Sometimes it's very hard to turn off my brain especially when I have an eighteen hour day. I try to stop working by 10 or 11pm but you know sometimes there is nothing I can do about it.
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.
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.
When looking at the brain, it is important to go beyond its structure to its function. This is because often in cognitive disorders, the structure of the brain is intact, but its function is compromised.
Science, already oppressive with its shocking revelations, will perhaps be the ultimate exterminator of our human species - if separate species we be - for its reserve of unguessed horrors could never be borne by mortal brains if loossed upon the world.
