First, let me say, I took so much from this book. I'm a cognitive science major myself and there were ideas in this book that hadn't ever come to my attention. I would like to say, however, that the chapter on connectionism didn't do the topic justice. Also, the book's chapters on the whole tend to mesh together to build up to the author's personal philosophical paradigm, extended mind hypothesis and largely embodied cognition (which is what most cognitive scientists believe). I find that in doing this, however, the reader misses out on the history and therefore context that these competing paradigms share.
Second, although this is a great book, I'm not sure I could recommend it to a layman audience. For that reason (not being as the title says, an introduction) I deducted one star from the review. However, if there's any philosophers of the mind, psychologists, biologists, or just curious people out there, I'd recommend this book to read for cognitive science (also, it helps a lot, for undergrad cog sci majors to give this a read before entering into your first cogs class).
