"The universe is run by extinction, by extermination, by gamma-ray bursts burning up a thousand garden worlds, by howling singularities eating up infant suns. And if life is to live, if anything is to survive through the end of all things, it will live not by the smile but by the sword, not in a soft place but in a hard hell, not in the rotting bog of artificial paradise but in the cold hard self-verifying truth of that one ultimate arbiter, the only judge, the power that is its own metric and its own source—existence, at any cost."
