Ursula K. Le Guin wrote a book called "Always Coming Home."

It includes a poem with this first line: "I don't care if I am possible."


The whole poem is like this:


NEWTON DID NOT SLEEP HERE

I don't care if I am possible.

What are the bridges between us?
Wind, the rainbow,
mist, still air.

We must learn to step on the rainbow.
(Even Old Jealousy called it covenant.)

We must learn how to walk the wind.

What links us (O my sister soul)
is the abyss between us.
We must learn from the fog paths.

What parts us (O my brother flesh)
is our kinship of one house.

We must learn to trust thin air.

--Ursula K. Le Guin, from "Always Coming Home."
