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

David Eagleman is neuroscientist at Baylor College of Medicine, where he directs the Laboratory for Perception and Action.

Rejecting evolution

Posted on by

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.”

 

Sum: Forty Tales from the Afterlives

Posted on by

I’m reading a wonderful little book by David Eagleman called Sum: Forty Tales from the Afterlives. But it’s really “an examination of what it means to live.” At first I marveled at the strangeness of some of the stories but realized none are stranger than the stories most of us grew up with (Bearded white man sitting on golden throne surrounded by harp playing angels). This is a book I’ll keep close and read again and again.

UPDATE (6/18/11):  I’m trying to savor these stories and make them last but I’m getting near the end and everyone is better than the one before. One of my favorites so far is Death Switch:

“So an afterlife does not exist for us per se, but instead an afterlife occurs for that which exists between us. When and alien civilization eventually bumps into Earth, they will immediately be able to understand what humans were about, because what will remain is the network of relationships: who loved whom, who competed, who cheated,who laughed together over road trips and holiday dinners. Each person’s ties to bosses, brothers ad lovers are etched into the electronic communiques. The death switches simulate the society so completely that the entire social network is reconstructable. The planet’s memories survive in zeros and ones.”

Author and broadcaster Stephen Fry reads from Sum: Forty Tales from the Afterlife, neuroscientist David Eagleman’s first work of fiction.

In The Plex

Posted on by

The full title of Steven Levy’s book is In the Plex: How Google Thinks, Works, and Shapes Our Lives. When I finished it I was pooped and a little depressed but I’m not sure I can explain either. Read the book and we’ll talk. [Good review in the Washington Post]

Looking back at some of the other books I’ve read about the Internet and technology, I think this might be my favorite. Up there with The Facebook Effect, Cluetrain Manifesto, and Cognitive Surplus.

David Kirkpatrick’s Facebook Effect was much kinder to Mark Zuckerberg than The Social Network but that story didn’t move me the way In the Plex did. And I’m sort of dreading the biography of Steve Jobs, though I can’t say why.

I used up some highlighter on this one and will add those passages here in a day or so.

Reality, there’s nothing like it

Posted on by

“We can’t comprehend Reality with our intellect. We can’t pull it into a static view of some thing. All our explanations are necessarily provisional. They’re just rigid frames of what is actually motion and fluidity. In other words, if you can think of how Reality is, you can be sure that’s how it isn’t. Reality simply cannot be put into a conceptual form — not even through analogy, for there’s nothing like it. Reality simply doesn’t fit into concepts at all. Nevertheless, Reality is something you can see. You can’t conceive of it, but you can perceive it.”
