Magic?

What we don't believe in, of course.  But which we know (somehow) would operate by rules and laws of its own, if it did exist, just like the empirical, number-based science of our own, existent universe.  Therefore, we can conclude--and do conclude--that a plurality of universes is conceivable, and that Magic itself is thus barely and provisionally possible.  That is the substratum of disbelief which, deliberately suspended, makes it possible for us in good conscience to enjoy A Midsummer Night's Dream and The Fairy Queen--and which enjoyment it annoys us to defend, as our Gallic cousins (the Frenchmen among us) are always requiring us to do.
