"The less anything is, the less we know it: how invisible, how unintelligible a thing, then, is this Nothing!" John Donne The "Nothing will come of nothing", of King Lear, seems in trouble, since von Neumann identified zero with the empty set and then identified one with the set which contains the empty set ... et cetera. And J.Conway defined a new family of numbers constructed out of sequences of binary choices. But is zero, or the empty set = nothing? Hmmmm ... definitely not for John Donne.
