I don't agree with absolutely everything Harris says, but it does make for a fascinating read (as does the entire book) and parts strike a chord, such as:
"It is worth noting that no one ever needs to identify himself as a non-astrologer or a non-alchemist. Consequently, we do not have words for people who deny the validity of these pseudo-disciplines. Likewise, atheism is a term that should not even exist. Atheism is nothing more than the noises reasonable people make when in the presence of religious dogma."
