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.
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.
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.
In every idea of genius or in every new human idea, or, more simply still, in every serious human idea born in anyone's brain, there is something that cannot possibly be conveyed to others.
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.
