"Judaism has some advantages over Christianity in that, for example, it does not proselytise—except among Jews—and it does not make the cretinous mistake of saying that the Messiah has already made his appearance. … However, along with Islam and Christianity, it does insist that some turgid and contradictory and sometimes evil and mad texts, obviously written by fairly unexceptional humans, are in fact the word of god. I think that the indispensable condition of any intellectual liberty is the realisation that there is no such thing."
