“The idea of safety had shrunk into particles - one snug moment, then the next. Meanwhile, the brain piped fugues of worry and staged mind-theaters full of tragedies and triumphs, because unfortunately, the fear of death does wonders to focus the mind, inspire creativity, and heightens the senses. Trusting one's hunches only seems gamble if one has time for seem; otherwise the brain goes on autopilot and trades the elite craft of analysis for the best rapid insights that float up from its danger files and ancient bag of tricks.”

“The mind boggles, in other words, but the brain toggles- sometimes quite rapidly, from one task to the next.”

“It wasn’t even one of those stoic pimples that goes quietly when you pop it; this one was cystic and painful and had roots that seemed to extend into my brain.”

“Our metaphors for the operation of the brain are frequently drawn from the production line. We think of the brain as a glorified sausage machine, taking in information from the senses, processing it and regurgitating it in a different form, as thoughts or actions. The digital computer reinforces this idea because it is quite explicitly a machine that does to information what a sausage machine does to pork. Indeed, the brain was the original inspiration and metaphor for the development of the digital computer, and early computers were often described as 'giant brains'. Unfortunately, neuroscientists have sometimes turned this analogy on its head, and based their models of brain function on the workings of the digital computer (for example by assuming that memory is separate and distinct from processing, as it is in a computer). This makes the whole metaphor dangerously self-reinforcing.”

“When one reads hurriedly and nervously, having in mind written tests and examinations, one's brain becomes encumbered with a lot of bric-a-brac for which there seems to be little use.”

“The sense of purity is a puzzling, and at times a fearful thing. It seems so noble, and it starts at one with morality. But it is a dangerous guide, and can lead us away not only from what is gracious, but also from what is good.”
