Sam Harris’ book The End of Faith is a critically insightful book.
He understands that at the heart of religion lies a realization about our own experience, but that that realization has been corrupted.
A particular way in which it has been corrupted, he says, is in the form of an Islam which preaches hatred and death. He makes a compelling case that that ideology represents a major threat to the entire world order. I myself am not nearly knowledgeable enough about that religion to judge his conclusions, but the case he makes is very strong.
Harris’ book resembles Dennett’s Breaking the Spell in its condemnation of “faith”, but is much more coherent and closely reasoned.
However, it fails to address a potentially key aspect of the problem: the neurological roots of people’s belief in religion.
