Crackpot, because I couldn't go through the first page with a straight face. It is attacking science for lacking rigor (why not, depending on your standards and the field) and ignoring a momentous event, then proceeds to put forth an explanation that is not rigorous at all (cultural arguments do not support neuroscience jargon).
First page of the website or the first page of the book?
Either way, you should spend more time reading it. Consider it science fiction if it bothers you.
"The origin of consciousness in the breakdown of the bicameral mind" is also mind blowing. Neither is foolproof, and both are potentially crackpot -- but if should read a crackpot book to broaden your horizons. Just consider it scifi instead of science.
