“Kids didn't have huge backpacks when I was their age. We didn't have backpacks at all. Now it seemed all the kids had them. You saw little second-graders bent over like sherpas, dragging themselves through the school doors under the weight of their packs. Some of the kids had their packs on rollers, hauling them like luggage at the airport. I didn't understand any of this. The world was becoming digital; everything was smaller and lighter. But kids at school lugged more weight than ever.”

“She had been living like a hermit herself, in a cramped, seedy apartment in Somerville, spending long hours in the lab. All-nighters had become a regular thing. She didn't have any close friends, didn't go out on dates, didn't even go to the movies by herself. She had sacrificed a normal life in order to get a PhD, and become a scientist.”

“Kids are more advanced these days. The teenage years now start at 11.”

“Parked in the school lot, I grab their two backpacks, which I swear weigh more than they do, get out, and open the back door like a chauffeur. Who am I kidding? Not like a chauffeur. I am a chauffeur. No one moves.”

“...we haven't had any accidents for months now...Everything on that island is perfectly fine.”

“But now science is the belief system that is hundreds of years old. And, like the medieval system before it, science is starting not to fit the world any more. Science has attained so much power that its practical limits begin to be apparent. Largely through science, billions of us live in one small world, densely packed and intercommunicating. But science cannot help us decide what to do with that world, or how to live. Science can make a nuclear reactor, but it cannot tell us not to build it. Science can make pesticide, but cannot tell us not to use it. And our world starts to seem polluted in fundamental ways---air, and water, and land---because of ungovernable science.”

“Professor Johnston often said that if you didn't know history, you didn't know anything. You were a leaf that didn't know it was part of a tree.”
