For some unknown reason, a nearby Barnes & Noble has Richard Meltzer’s Autumn Rhythm: Musings on Time, Tide, Aging, Dying and Such Biz (Da Capo Press; $14.00) shelved in the philosophy section. It puzzled me why it was there. Before I read it. And afterwards. Perhaps someone noted he’d written a book titled The Aesthetics of Rock and figured the man must be some sort of Schopenhauer or something, someone who switched from writing about the positives (rock) to something more dour (death). Maybe it was a joke played by a waggish, underpaid book monger. Or maybe it was a case of someone wanting to keep it in the store while saving enough scratch to buy the hardcover version, so taking it out of the music section seemed like a good plan. If the latter, then the paperback price noted above is certainly a savings. If it is the middle, then the joke is piss poor, or not really funny: someone who is truly looking for enlightenment of any sort who picks up the book might as well be looking at the ground in the bottom of their venti coffee cup. And if it is the first name, then the shelver in question is probably moving the Martha Stewart cooking and home decorating books to the “true crime” section.
