“We live in the Age of the Higher Brain, the cerebral cortex that has grown enormously over the last few millennia, overshadowing the ancient, instinctive lower brain. The cortex is often called the new brain, yet the old brain held sway in humans for millions of years, as it does today in most living things. The old brain can’t conjure up ideas or read. But it does possess the power to feel and, above all, to be. It was the old brain that caused our forebears to sense the closeness of a mysterious presence everywhere in Nature.”

“We are part of nature, a product of a long evolutionary journey. To some degree, we carry the ancient oceans in our blood. … Our brains and nervous systems did not suddenly spring into existence without long antecedents in natural history. That which we most prize as integral to our humanity - our extraordinary capacity to think on complex conceptual levels - can be traced back to the nerve network of primitive invertebrates, the ganglia of a mollusk, the spinal cord of a fish, the brain of an amphibian, and the cerebral cortex of a primate.”

“The brain is full of lonely ideas, begging you to make some sense of them, to recognize them as interesting. The lazy brain just files them away in old pigeonholes, like a bureaucrat who wants an easy life. The lively brain picks and chooses and creates new works of art out of ideas.”

“First, we cannot overload the human brain. This divinely created brain has fourteen billion cells. If used to the maximum, this human computer inside our heads could contain all the knowledge of humanity from the beginning of the world to the present and still have room left over. Second, not only can we not overload our brain - we also know that our brain retains everything. I often use saying that "The brain acquires everything that we encounter." The difficulty does not come with the input of information, but getting it out. Sometimes we "file" information randomly of little importance, and it confuses us.”

“Imagining you are going to die is all part of that third brain… the neo-cortex. That’s where the Landlord really screwed up.”

“I'm a century old, an impossible age, and my brain has no anchor in the present. Instead it drifts, nearly always to the same shore. Today, as most days, it is 1962. The year I discovered love.”
