“Some of the test subjects were given cards that had both words printed in full, like this:Hot: ColdOthers used cards that showed only the first letter of the second word, like this:Hot: CThe people who used the cards with the missing letters performed much better in a subsequent test measuring how well they remembered the word pairs. Simply forcing their minds to fill in a blank, to act rather than observe, led to stronger retention of information.”

“What the Net seems to be doing is chipping away my capacity for concentration and contemplation. Whether I’m online or not, my mind now expects to take in information the way the Net distributes it: in a swiftly moving stream of particles. Once I was a scuba diver in the sea of words. Now I zip along the surface like a guy on a Jet Ski.”

“The Net’s interactivity gives us powerful new tools for finding information, expressing ourselves, and conversing with others. It also turns us into lab rats constantly pressing levers to get tiny pellets of social or intellectual nourishment.”

“Looking ahead to future applications of electronics, [de Forest] grew even gloomier. He believed that 'electron physiologists' would eventually be able to monitor and analyze 'thought or brain waves', allowing 'joy and grief to be measured in define, quantitative unit.' Ultimately, he concluded, 'a professor may be able to implant knowledge into the reluctant brains of his 22nd century pupils. What terrifying political possibilities may be lurking there! Let us be thankful that such things are only for posterity, not for us.”

“Their words also make it a lot easier for people to justify that shift -- to convince themselves that surfing the Web is a suitable, even superior, substitute for deep reading and other forms of calm and attentive thought. In arguing that books are archaic and dispensable, Federman and Shirky provide the intellectual cover that allows thoughtful people to slip comfortably in the permanent state of distractedness that defines the online life.”

“We become, neurologically, what we think."(33)”

“To remain vital, culture must be renewed in the minds of the members of every generation. Outsource memory, and culture withers.”

“[Patricia Greenfield] concluded that “every medium develops some cognitive skills at the expense of others.” Our growing use of the Net and other screen-based technologies has led to the “widespread and sophisticated development of visual-spatial skills.” We can, for example, rotate objects in our minds better than we used to be able to. But our “new strengths in visual-spatial intelligence” go hand in hand with a weakening of our capacities for the kind of “deep processing” that underpins “mindful knowledge acquisition, inductive analysis, critical thinking, imagination, and reflection.”

“Technology isn’t what makes us “post-human” or “transhuman,” as some writers and scholars have recently suggested. It’s what makes us human. Technology is in our nature. Through our tools we give our dreams form. We bring them into the world. The practicality of technology may distinguish it from art, but both spring from a similar, distinctly human yearning.”

“As a society, we've become suspicious of such acts. Out of ignorance or laziness or timidity, we've turned the Luddites into caricatures, emblems of backwardness. We assume that anyone who rejects a new tool in favor of an older one is guilty of nostalgia, of making choices sentimentally rather than rationally. But the real sentimental fallacy is the assumption that the new thing is always better suited to our purposes and intentions than the old thing. That's the view of a child, naive and pliable. What makes one tool superior to another has nothing to do with how new it is. What matters is how it enlarges us or diminishes us, how it shapes our experience of nature and culture and one another. To cede choices about the texture of our daily lives to a grand abstraction called progress is folly.”

“When an inscrutable technology becomes an invisible technology, we would be wise to be concerned. At that point, the technology's assumptions and intentions have infiltrated our own desires and actions. We no longer know whether the software is aiding s or controlling us. We're behind the wheel, but we can't be sure who's driving.”
