Evolve solutions; when you find a good one, don't stop.

The left hemisphere acts as an "interpreter," watching the actions and behaviors of the body and assigning a coherent narrative to these events. And the left hemisphere works this way even in normal, intact brains. Hidden programs drive actions, and the left hemisphere makes justifications. This idea of retrospective storytelling suggests that we come to know our own attitudes and emotions, at least partially, by inferring them from observations of our own behavior.

Even while it's true that we are tied to our molecules and proteins and neurons - as strokes and hormones and drugs and microorganisms indisputably tell us - it does not logically follow that humans are best described only as pieces and parts.

Many people prefer a view of human nature that includes a true side and a false side - in other words, humans have a single genuine aim and the rest is decoration, evasion, or cover-up. That's intuitive, but it's incomplete. A study of the brain necessitates a more nuanced view of human nature.

All activity in the brain is driven by other activity in the brain, in a vastly complex, interconnected network.

There is a looming chasm between what your brain knows and what your mind is capable of accessing.

As Carl Jung put it, "In each of us there is another whom we do not know." As Pink Floyd sang, "There's someone in my head, but it's not me."
