Incognito – The Secret Lives of the Brain by David Eagleman

Posted on by

It’s easy to think of “me” has “having” a brain, but this book left me thinking my brain has me. If there is a me apart from my brain, I fear it’s mostly along for the ride. Here are some ideas that brought out my highlighter.

The brain generally does not need to know most things; it merely knows how to go out and retrieve the data. It computes on a need-to-know basis. pg 28

You’re not perceiving what’s out there. You’re perceiving whatever your brain tells you. pg 33

We have no access to the rapid and automatic machinery that gathers and estimates the statistics of the world. pg 34

Your brain is in the dark but your mind constructs light. pg 40

The difference between being awake and being asleep is merely that the data coming in from the eyes anchors the perception. Asleep vision (dreaming) is perception that is not tied down to anything in the real world; waking perception is something like dreaming with a little more commitment to what’s in front of you. pg 45

It’s easy to spot a hallucination only when it’s bizarre. For all we know, we hallucinate all the time. pg 46

Our expectations influence what we see. There has to be a match between your expectations and the incoming data for you to “see” anything. Awareness of your surroundings occurs only when sensory inputs violate expectations. pg 48, 50

The brain refines its model of the world by paying attention to its mistakes. pg 49

The brain tries to see the world only as well as it needs to. We are not conscious of most things until we ask ourselves questions about them. What we perceive in the outside world is generated by parts of the brain to which we do not have access. pg 54

Instead of reality being passively recorded by the brain, it is actively constructed by it. pg 82

There are thoughts you cannot think. pg 82

Evolution has carefully carved your eyes, internal organs,sexual organs, and so on — and also the character of your thoughts and beliefs. pg 82

“In general, we’re least aware of what our minds do best.” — Marvin Minsky, The Society of Mind

We are not able to see the instincts that are the very engines of our behavior. These programs are inaccessible to us not because they are unimportant, but because they’re critical. Conscious meddling would do nothing to improve them. pg88

Briefly glimpsed people are more beautiful. pg 92

We come to know our own attitudes and emotions, at least partially, by inferring them from observations of our own behavior. pg 134

Rejecting evolution

Jonathan Dudley is the author of Broken Words: The Abuse of Science and Faith in American Politics

“…creationism has failed to provide an alternative explanation for the vast majority of evidence explained by evolution.

It has failed to explain why birds still carry genes to make teeth, whales to make legs, and humans to make tails.

It has failed to explain why the fossil record proposed by modern scientists can be used to make precise and accurate predictions about the location of transition fossils.

It has failed to explain why the fossil record demonstrates a precise order, with simple organisms in the deepest rocks and more complex ones toward the surface.

It has failed to explain why today’s animals live in the same geographical area as fossils of similar species.

It has failed to explain why, if carnivorous dinosaurs lived at the same time as modern animals, we don’t find the fossils of modern animals in the stomachs of fossilized dinosaurs.

It has failed to explain the broken genes that litter the DNA of humans and apes but are functional in lower vertebrates.

It has failed to explain how the genetic diversity we observe among humans could have arisen in a few thousand years from two biological ancestors.

“…the belief that scientists can discover truth, and that, once sufficiently debated, challenged and modified, it should be accepted even if it creates tensions for familiar belief systems, has an obvious impact on decisions that are made everyday. And it is that belief Christians reject when they reject evolution.

In doing so, they’ve not only led America astray on questions ranging from the value of stem cell research to the etiology of homosexuality to the causes of global warming. They’ve also abandoned a central commitment of orthodox Christianity.”

 

“If I can just hang on for another couple of years”

“This idea of “hanging on for another few years” isn’t just dangerous; it’s suicidal. I know this comes off as harsh, but media companies should be asking themselves this question (actually, they should have been already): Is our topmost leadership capable of looking past their personal needs to do what’s right for the company in the long run? In the answer to that question lies the future of all media.”

2030: The real story of what happens to America

Posted on by

I’m a big fan of Albert Brooks. Defending Your Life, Lost in America, Taxi Driver, Private Benjamin… pick your favorite. He writes, directs, acts… TV, movies and, now, novels.

I just finished 2030 and found it both depressing and inspiring. Here’s a little taste from a NYT review:

In the future America of “2030,” the national debt has long since surpassed the gross national product. Why anyone would want to be president is “more and more of a mystery.” On the rosy side — well, sort of — a cure for cancer has been found, turning the man who did it, Dr. Sam Mueller, into a billionaire and a guru.

The bad news? Along with a stock of lesser rejuvenating drugs and gadgets, Mueller’s breakthrough has left spry hordes of senior citizens cheerily hogging most of the country’s remaining resources. Seeing their own chance at the good life shrink to zero, young people are forming “resentment gangs” and committing acts of escalating violence against “the olds.” The White House’s first Jewish occupant, the brainy but melancholy Matthew Bernstein, would like to give them a fairer share of the pie, but even he doesn’t dare risk the wrath of AARP.

I have to say that just about everything in this story seemed plausible to me. Brooks fans won’t be disappointed. A few excerpts after the jump… Continue reading →
