A long time ago Wendell Berry wrote a poem, "To The Unseeable Animal," which he introduces by quoting his daughter who, I am sure, inspired the poem that followed:
My daughter: "I hope there's an animal
somewhere that nobody has ever seen.
And I hope nobody ever sees it."
I confess it as a weakness, that it occurred to me that this poses an interesting puzzle to a quantum theoretician interested in the riddle of Schroedinger's Cat. It further occurs to me that that puzzle might contain, or be, its own solution. Ah, physics; ah, mathematics; ah, logic -- how readily and how eagerly you intrude. Quiet yourselves.
Set all that aside: Wendell writes the poem to the unseeable animal, and ends it thus:
That we do not know you
is your perfection
and our hope. The darkness
keeps us near you.
The full poem is on p. 118 of Farming: A Hand Book, by Wendell Berry.
