>I agree with the Language Instinct since it sticks with our current scientific understanding of how the brain scientifically and mathematically creates grammar. I disagree with much of The Better Angels book since it contradicts many anthropological and archaeological studies of human societies.

So you agree with "The Language Instinct" because it supports the prevailing view and you disagree with "The Better Angels..." because it doesn't. Why the appeal to authority? Why not judge the books on their arguments and evidence?
