Science fiction isn’t just thinking about the world out there. It’s also thinking about how that world might be — a particularly important exercise for those who are oppressed, because if they’re going to change the world we live in, they — and all of us — have to be able to think about a world that works differently.
“People die because they remain where they are, so perhaps eternal life is travel is forgetting. Limits, it might be, are precisely what make traveling and forgetting, and consequently immortality, possible, because those limits are also what prevent me from ever reaching the end of the world forever and ever, ahem.”
