Oh, adjust yourself. You people have spent ten millennia playing at soldiers while becoming ever more dedicated civilians. We've spent the last thous… - Iain Banks

It’s as if I drifted into this situation. I didn’t ever think about fighting or doing anything risky at all, not until the war came along. I agreed it was necessary, but that seemed obvious; everybody thought so, everybody I knew, anyway. And volunteering, agreeing to take part; that too seemed... natural. I knew I might die, but I was prepared to risk that; it was almost romantic. Somehow it never occurred to me that it might entail privation and suffering. Am I as stupid as those throughout history—those I’ve always despised and pitied—who’ve marched off to war, heads full of noble notions and expectations of easy glory, only to die screaming and torn in the mud?

To a gun, all problems resolved into what could be shot at.

The war won't end," Aviger said. "It'll just die away...I don't think the Culture will give in like everybody thinks it will. I think they'll keep fighting because they believe in it. The Idirans won't give in, either; they'll keep fighting to the last, and they and the Culture will just keep going at each other all the time, all over the galaxy eventually, and their weapons and bombs and rays and things will just keep getting better and better, and in the end the whole galaxy will become a battleground until they've blown up all the stars and planets and Orbitals and everything else big enough to stand on, and then they'll destroy all of each other's big ships and then the little ships, too, until everybody'll be living in single units blowing each other up with weapons that could destroy a planet...and that's how it'll end; probably they'll invent guns or drones that are even smaller, and there'll only be a few smaller and smaller machines fighting over whatever's left of the galaxy, and there'll be nobody left to know how it all started in the first place.
