Reddit reviews Magic, Power, Language, Symbol: A Magician's Exploration of Linguistics

In some ways, I think it is a relief to believe magic is scientifically untestable. If it were testable, we'd likely have already done it, or else we are technologically incapable of doing so (and likely would be for the remainder of our lifetimes). Dunn gives some pretty convincing arguments for how (despite being ascientific) magic still works, and that's what really matters. There may be no Santa Claus, but we still get presents.

Postmodern Magic was written as a practical guide for absolute beginners, but he has a fresh perspective that makes it one of my favorite books. He consistently looks at things from an information theory point of view. If you enjoy that, he also has a blog and another book which are occasionally insightful.
