Rhetoric as Epistemic

Jane Hirshfield's "Against Certainty":

"There is something out in the dark that wants to correct us.
Each time I think "this," it answers "that."
Answers hard, in the heart-grammar's strictness.

If I then say "that," it too is taken away.

Between certainty and the real, an ancient enmity.
When the cat waits in the path-hedge,
no cell of her body is not waiting.
This is how she is able so completely to disappear.

I would like to enter the silence portion as she does.

To live amid the great vanishing as a cat must live,
one shadow fully at ease inside another."

(Jane Hirshfield, "Against Certainty," from After: Poems, 2006).
