[The haggadah] was made to teach, and it will continue to teach. And it might teach a lot more than just the Exodus story.What do you mean?Well, from what you've told me, the book has survived the same human disaster over and over again. Think about it. You've got a society where people tolerate difference, like Spain in the Convivencia, and everything's humming along: creative, prosperous. Then somehow this fear, this hate, this need to demonize 'the other' -- it just sort of rears up and smashes the whole society. Inquisition, Nazis, extremist Serb nationalists... same old, same old. It seems to me that the book, at this point, bears witness to all that.
