Quote #10

"We train our commanders the way we do because that's what it takes – they have to think in certain ways, they can't be distracted by a lot of things, so we isolate them. You. Keep you separate. And it works. But it's so easy, when you never meet people, when you never know the Earth itself, when you live with metal walls keeping out the cold of space, it's easy to forget why Earth is worth saving. Why the world of people might be worth the price you pay." (13.193)

Is it true to say that Ender hasn’t met people? Isn’t Battle School full of people? And why does the army need to isolate people when those people are these super-genius kids? After all, the army wants Ender to remain creative, but isn’t his creativity helped by his relationships with Alai and Bean? Graff lays out the reason why they do what they do here – and it’s a story we’ve heard before. But we hear it so many times that we can’t help thinking of some problems.
