Sam Harris on the creator writing books (too many)

Our situation is this: most of the people in this world believe that the Creator of the universe has written a book. We have the misfortune of having many such books on hand, each making an exclusive claim as to its infallibility. People tend to organize themselves into factions according to which of these incompatible claims they accept—rather than on the basis of language, skin color, location of birth, or any other criterion of tribalism. Each of these texts urges its readers to adopt a variety of beliefs and practices, some of which are benign, many of which are not. All are in perverse agreement on one point of fundamental importance, however: "respect" for other faiths, or for the views of unbelievers, is not an attitude that God endorses. While all faiths have been touched, here and there, by the spirit of ecumenicalism, the central tenet of every religious tradition is that all others are mere repositories of error or, at best, dangerously incomplete. Intolerance is thus intrinsic to every creed. Once a person believes—really believes—that certain ideas can lead to eternal happiness, or to its antithesis, he cannot tolerate the possibility that the people he loves might be led astray by the blandishments of unbelievers. Certainty about the next life is simply incompatible with tolerance in this one. - Sam Harris
