Top 15 Michael S. Gazzaniga Quotes

Science results from a profoundly social process. The common portrayal — that science emerges from a solitary isolated genius, always laboring alone, not owing anything to anyone — is simply wrong.

The brain has millions of local processors making important decisions. It is a highly specialized system with critical networks distributed throughout the 1,300 grams of tissue. There is no one boss in the brain. You are certainly not the boss of the brain. Have you ever succeeded in telling your brain to shut up already and go to sleep?

Chaos doesn’t mean that the system is behaving randomly, it means that it is unpredictable because it has many variables, it is too complex to measure, and even if it could be measured, theoretically the measurement cannot be done accurately and the tiniest inaccuracy would change the end result an enormous amount.

I believe that things just happen in life, and pretty much after the fact, we make up a story to make it all seem rational. We all like simple stories that suggest a causal chain to life’s events. Yet randomness is ever present.

Our brains renew themselves throughout life to an extent previously thought not possible.

Baruch Spinoza, who said, “There is no mind absolute or free will, but the mind is determined for willing this or that by a cause which is determined in its turn by another cause, and this one again by another, and so on to infinity.

the study of psychophysics proves that it is impossible to bore a German.” Thankfully,

Reductionism in the physical sciences has been challenged by the principle of emergence. The whole system acquires qualitatively new properties that cannot be predicted from the simple addition of those of its individual components. One might apply the aphorism that the new system is greater than the sum of its parts. There is a phase shift, a change in the organizational structure, going from one scale to the next.

Newton’s laws aren’t fundamental, they are emergent; that is, they are what happens when quantum matter aggregates into macroscopic fluids and objects. It is a collective organizational phenomenon.

We live in the era of the “bottom line” mentality, with TED talks, sound bites, and news summaries. There is so much information to digest, we can only hope to grasp the world with compact and seemingly complete stories. We don’t want to be left dangling.
We are all suckers for this information diet, and we all have come to depend on it, just like we have all succumbed to the instant gratification of texting and cell phones. And yet what separates the dilettante from the sophisticate is the appreciation that everything is not simple. The trick seems to be able to talk clearly while remaining fully aware of the underlying complexity of any story. For me it is the overwhelming realization that when trying to figure out how the brain does its masterful trick of
enabling minds, we are barely at the starting line. Dig as deep as you want into human history: As long as there is a written record of thought, there is a record of humans wondering about the nature of life. It becomes obvious that all of us are just hopping into an ongoing conversation, not structuring one with a beginning, a middle, and an end. Humans may have discovered some of the constraints on the thought processes, but we have not yet been able to tell the full story.

The classic example from biology is the huge, towerlike structure that is built by some ant and termite species. These structures only emerge when the ant colony reaches a certain size (more is different) and could never be predicted by studying the behavior of single insects in small colonies.

"At the end of the visit Steve asked, "What percent of the work is exciting?" After thinking for a moment, I replied, "Oh about ten percent. The rest is routine." As I have learned in life, 10 percent is a good number for most professions. I know it has been enough to keep me going to work every day with a smile on my face."

The arts are not frosting but baking soda.

stimulation of the medial frontal cortex gives one the feeling of the urge to move

Our subjective awareness arises out of our dominant left hemisphere’s unrelenting quest to explain these bits and pieces that have popped into consciousness. Notice that popped is in the past tense. This is a post hoc rationalization process. The interpreter that weaves our story only weaves what makes it into consciousness. Because consciousness is a slow process, whatever has made it to consciousness has already happened. It is a fait accompli. As we saw in my story at the beginning of the chapter, I had already jumped before I realized whether I had seen a snake or if it was the wind rustling the grass. What does it mean that we build our theories about ourselves after the fact? How much of the time are we confabulating, giving a fictitious account of a past event, believing it to be true? This post hoc interpreting process has implications for and an impact on the big questions of free will and determinism
