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.
We are the only species on the planet, so far as we know, to have invented a communal memory stored neither in our genes nor in our brains. The warehouse of this memory is called the library
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.
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.
There are three kinds of brains: One understands of itself, another can be taught to understand, and the third can neither understand to itself or be taught to understand.
We admit, in geometry, not only infinite magnitudes, that is to say, magnitudes greater than any assignable magnitude, but infinite magnitudes infinitely greater, the one than the other. This astonishes our dimension of brains, which is only about six inches long, five broad, and six in depth, in the largest heads.
