Just as a matter of interest....
Is anything the opposite of anything?
Can I have some examples, please? I seem to remember learning at school when I was six that up was actually the opposite of down. I must have remembered wrong, though, because there are so many intelligent people here that they couldn't possibly all be saying something really, really silly, could they?
I would say existence and non-existence, but some of the weirder things that Quantum Mechanics implies for really short timespans and really small lengths says I am wrong (photons appearing out of nothing, quantum foam, and all that jazz).
The empty set and the set of all sets that are not the empty set, but that is just mathematics.
