Is there such a thing as a magic number? Many will say it is "three." After all, it was Isaiah who cried "kadosh, kadosh, kadosh!" But three isn't always the magic number. Otherwise, there wouldn't be so many Beatles songs which start out with 1-2-3-4! Seven is the magic number for the length of the week, though we can't really explain why. Don't forget about three, though: in his play Penthesilea, Kleist showed how in the dualistic "battle of the sexes" a third way can transcend masculine and feminine.
