I really like "When Harry Met Sally." It has interesting dialogue, a happy ending, and its just fun. I knew from the first time I saw it that Harry's intellectual posturing during the car ride to New York was crap. Now I know why I know it's crap. Here's the beginning of the movie; if you watch from 4:46 you see and hear the conversation about death.
Watching The Atheist Experience #670: Coming Out Atheist, a caller asked about the happiness and morality of atheists. They recommended The Conquest of Happiness by Bertrand Russell which I quickly google'd and discovered for free on Google. Almost the entire book can be read for free here. I'm not very far into it yet, but Russell has already debunked in Chapter 2 the idea that there is something better about feeling yourself enlightened or superior because you are unhappy. It is not your great wisdom that makes you unhappy, it's folly.
I earnestly look forward to reading more, as time and classes permit. Happy new school year!
