You can take a book to the beach without worrying about sand getting in its works. You can take it to bed without being nervous about it falling to the floor should you nod off. You can spill coffee on it. You can sit on it. You can put it down on a table, open to the page you're reading, and when you pick it up a few days later it will still be exactly as you left it. You never have to be concerned about plugging a book into an outlet or having its battery die.

The book, I think, like the map before it, like the clock, created or help create a revolution in the human mind in the way our habits of mind and ultimately the way we use our brains.

There are a whole lot of reasons to be very happy that our brains are able to adapt and adapt so readily because we do strengthen and become more efficient at things we do a lot of in changed ways of thinking that we might need.

The only thing going on is the progression of words and sentences across page after page and so suddenly we see this immersive kind of very attentive thinking, whether you are paying attention to a story or to an argument, or whatever. And what we know about the brain is the brain adapts to these types of tools.

We don’t constrain our mental powers when we store new long-term memories. We strengthen them. With each expansion of our memory comes an enlargement of our intelligence. The Web provides a convenient and compelling supplement to personal memory - but when we start using the Web as a substitute for personal memory, by bypassing the inner processes of consolidation, we risk emptying our minds of their riches.

What I had thought were signs of a broken educational system - the seemingly random placement of commas, the spastic syntax, the obnoxious overuse of quotation marks, the goofy misspelling of 'Jouralism' - were actually signs of the New Instantaneousness. 'Instant Jouralists' cannot be concerned with punctuation and grammar and spelling. That stuff just 'slows you down.' To be an 'Instant Jouralist,' you have to write as if you were being pursued by a cheetah across the Serengeti.

Culture is sustained in our synapses...It's more than what can be reduced to binary code and uploaded onto the Net. To remain vital, culture must be renewed in the minds of the members of every generation. Outsource memory, and culture withers.
