Today the mind is not part of the weather,
Today the air is clear of everything.
It has no knowledge except of nothingness
And it flows over us without meanings,
As if none of us had ever been here before
And are not now: in this shallow spectacle,
This invisible activity, this sense.
—Wallace Stevens, from “A Clear Day and No Memories,” Opus Posthumous Poems, Plays, Prose, ed. Milton J. Bates (Vintage Books, 1989)
