> Like all real literature, it aims above all to tell a truth, however roughly it goes down.
I wish this statement and its ilk were less common; in my opinion it's either a platitude or false. For example, another plausible raison d'etre: to share an observation. It's not hard to think of others. Now you could say there's necessarily some higher truth encoded in any meaningful observation. But, in my opinion, that line of reasoning ends with the quoted statement being a platitude.
This point could be pedantry, but I make it because I get the feeling the article's author would say Pausch's "the Last Lecture" is not "real literature" because it's purpose is mostly to make people feel good.
I'd also add Hitchens book "Mortality" as a suggestion too.
I pose it as if I enjoyed it, but I didn't - it was a terrifying read. Makes you wonder, you know, what to do with your own life (which is to plug the gap with a platitude). Maybe Alan Clark would have been saved if he'd regularly procrastinated on Hacker News? Fingers crossed.
