I've been reading the aggressively assertive essay collection, "We're Doomed. Now What?" by Roy Scranton. Enjoyment isn't the word I'd use exactly to describe the experience, but it's certainly compelling.
In the opening essay, he quotes Nietzche and DeLillo and both these quotes really struck me, so I just wanted to re-post them here:
Nietzche: "Man will sooner will nothingness than not will." (I know, it's a little densely phrased - I like Scranton's interpretation, 'We would choose meaningful self-annihilation over meaningless bare life.')
DeLillo, from a character from White Noise: "War is the form nostalgia takes when men are hard-pressed to say something good about their country."
