One of the things I appreciated about Harris's book is his approach to the subject. He is an atheist, neuroscientist, and part of the 4 horsemen of the apocalypse. He gets heat from both sides of the divide with his premise. Theists for taking their cherished religious enlightenment experiences and applying the scientific method to it. Atheists for using the term spirituality in anything but negative terms.
He postulates that the only way to help people get free from religion is to address their woo and apply the scientific method to it. Much like religion stated that they hold the only means to morality. He also shows how near death experiences are similar to those in deep meditation.
I believe the only way we can win this battle against the evil of religion is to confront it on every front. Scientists like Harris, are doing this. Harris with the micro or inner workings of the mind and Krauss with the macro with the beginning of the universe. These are the areas theists and religionists use as a last resort to end discussions. Once these are fully vetted out there will be no other arena for them to go.
