The phenomenon of religious extremism and violence committed in the name of God. If religion is perceived as being part of the problem, Rabbi Sacks argues, then it must also form part of the solution. When religion becomes a zero-sum conceit -- that is, my religion is the only right path to God, therefore your religion is by definition wrong -- and individuals are motivated by what Rabbi Sacks calls "altruistic evil," violence between peoples of different beliefs appears to be the only natural outcome. But through an exploration of the roots of violence and its relationship to religion, and employing groundbreaking biblical analysis and interpretation, Rabbi Sacks shows that religiously inspired violence has as its source misreadings of biblical texts at the heart of all three Abrahamic faiths.
