Let me tell you about unicorns. Unicorns are white-coated creatures, with bodies resembling those of horses. The unicorn’s hooves are cloven, and it has a single, spiral horn protruding from its forehead. The horn has a property which allows it to purify water and cure disease on contact. The animal itself has the ability to detect human female virginity and is highly attracted to the same, so much so that it exhibits a stereotypical set of behaviors in the presence of said females.
I can now make some meaningful statements about unicorns. I can say, for instance, “A unicorn is a unicorn if and only if it has one horn.”
I now say, “You should be able to recognize a unicorn if you see one.” Is that true? If it is true, what about it is true? That is to say: Does my statement reference a unicorn, the inherent possibility of a unicorn, or all that stuff I just said about unicorns? If it is the latter, does that necessitate anything beyond a bare, opaque unity?
