By David Shermer. Has anyone else read this book? Shermer is the editor of Skeptic magazine, and has spent a lot of time investigating fantastic and fringe claims. He really understands what science IS, and understands how to apply it to things like intelligent design and psychic claims. The book is largely divided into five parts---the middle three parts are dedicated to witch hunts, creationism, and Holocause denial, respectively. He doesn't seem to come up with any new conclusions (I haven't read the last part, where all of the conclusions would presumably be made explicit), but it is an interesting read nonetheless. For example, one chapter gives 25 arguments agains Creationist claims. There are no real arguments here that an intelligent person couldn't construct for themselves, but there is lots of references that will lead you to a deeper understanding of WHY things like Intelligent Design aren't science. Shermer's main point is that people who believe weird things aren't any less intelligent than anyone else, they have just convinced themselves that they aren't wrong through faulty logic. This is a great book to read if you've ever wrangled with anyone here on SciForums, like Farsight or IceAgeCivilizations.
