“You', the ego, live in your left brain. When we say that man is the only creature who spends 99 per cent of his time inside his own head, we mean, in fact, inside his left cerebral hemisphere. And in the basement of the left hemisphere is the library full of filing cabinets -- the stuffy room that we mistake for reality.”

“The next phase of the work was when Joseph LeDoux and I came up with the idea of the interpreter. Twenty-five years into studying these patients we finally got around to asking the patients, "Why did you do that?" after they had a response with the left hand that was being governed by the separated, silent, speechless right hemisphere. We began to understand that the left hemisphere "made up" a story as to why the patient did what he/she did, and in that moment we began to see the cardinal feature of the left hemisphere: the ability to interpret actions generated outside its realm of conscious awareness.”

“Left hemisphere industrialism has blinded the Chinese to the effects of our alphabet: pattern recognition is in the right hemisphere.”

“There is no way to tell whether the patterns extracted by the right hemisphere are real or imagined without subjecting them to left-hemisphere scrutiny. On the other hand, mere critical thinking, without creative and intuitive insights, without the search for new patterns, is sterile and doomed. To solve complex problems in changing circumstances requires the activity of both cerebral hemispheres: the path to the future lies through the corpus callosum.”

“Cultural dominance by either the left or the right hemisphere is largely dependent upon environmental factors.”

“I began to feel that all the people I'd ever known who had died or left me had not in fact gone away, but continued to live on inside me just as this man's wife lived on inside him.”

“There is no doubt that right-hemisphere intuitive thinking may perceive patterns and connections too difficult for the left hemisphere; but it may also detect patterns where none exist. Skeptical and critical thinking is not a hallmark of the right hemisphere. And unalloyed right-hemisphere doctrines, particularly when they are invented during new and trying circumstances, may be erroneous or paranoid.”

“There are people who have too much space between their ears, and given the time, do nothing but free fall forever inside their head. It's a spooky thing to be left alone inside an angry innerverse.”

“There is no such thing as the Shadow Cabinet. It is purely a Press term. The Prime Minister is by no means bound to include the members of the Shadow Cabinet in his Cabinet, or even in the Government. I myself left several out.”

“Sooner or later, if human society is to evolve—indeed, if it is to survive—we must match our lives to our new knowledge. For too long, the Two Cultures—the esthetic, feeling humanities and cool, analytical science—have functioned independently, like the right and left hemispheres of a split-brain patient. We have been the victims of our collective divided consciousness.”
