When I was a kid, my whole circle of D&D-playing, science-fiction reading pals was really into Roger Zelazny's ten-volume Chronicles of Amber, but somehow I never read it; for years, I'd intended to correct this oversight, but I never seemed to find the time — after all, there's more amazing new stuff than I can possibly read, how could I justify looking backwards, especially over the course of ten books?
Fantasy and science fiction author and political activist Steven Brust (previously) was this year's Guest of Honor at Philcon, an excellent Philadelphia-area science fiction (I have also had the privilege to be Philcon's GoH, and it's a great con); his guest of honor speech is entitled Truth as a Vehicle for Enhancing Fiction, Fiction as a Vehicle for Discovering Truth, and he's posted a transcript to his blog.
When I was a kid, we used to sing Merle Travis's Sixteen Tons in the car on long trips: it's a poetic masterpiece, capturing the clash between a worker's proud and indomitable spirit and his impossible, inescapable poverty trap (chances are you've heard Tennessee Ernie Ford or Johnny Cash perform it).
