“But I am designed to last forever," said the expendable, "if not interfered with.""Isn't that nice? Expendable yet eternal. You'll be able to go back and observe any part of human history that you wish. Watch the pyramids being unbuilt. See the ice ages go and come in reverse. Watch the de-extinction of the dinosaurs as a meteor leaps out of the Gulf of Mexico.""I will have no useful task. I will not be able to help the human race in any way. My existence will have no meaning after you are dead.""Now you know how humans feel all the time.”

“Would I be happy if I discovered that I could go to heaven forever? And the answer is no. Consider this argument. Think about what is forever. And think about the fact that the human mind, the entire human being, is built to last a certain period of time. Our programmed hormonal systems, the way we learn, the way we settle upon beliefs, and the way we love are all temporary. Because we go through a life's cycle. Now, if we were to be plucked out at the age of 12 or 56 or whenever, and taken up and told, "Now you will continue your existence as you are. We're not going to blot out your memories. We're not going to diminish your desires." You will exist in a state of bliss - whatever that is - forever. [...] Now think, a trillion times a trillion years. Enough time for universes like this one to be born, explode, form countless star systems and planets, then fade away to entropy. You will sit there watching this happen millions and millions of times and that will be just the beginning of the eternity that you've been consigned to bliss in this existence.”

“But I'll never see any of those fish," said Maxie."Or those whales. Or any lions or tigers. I'm never going to set foot in a rain forest now, am I? I won't even be able to watch old DVD's about them without electricity. What does the future hold? It's like going back to the middle ages. Nobody knowing what was going on beyond their front doorstep. All I'll ever know is this. This little bit of London.”

“Is the system going to flatten you out and deny you your humanity, or are you going to be able to make use of the system to the attainment of human purposes?”

“You oughtn't to see this," Will muttered in my ear. "You'll never want to have a baby if you do. They oughtn't to let women watch. It'll be the end of the human race.”

“Well, I mean I have forgotten how to go anywhere alone. There are things you have to do. Like throw money into a toll basket on a highway. I'd pull up to it now and panic. Or what if I had to hail a cab? It's hard to believe, but I used to be able to do things when I was twenty that are impossible now [...] It's more than the physical task. It's ...a vision of yourself. If you don't see yourself as being able to do it, then you can't, no matter how easy it is.”
