Through intricate motions ran
Stream and gliding sun
And all my heart seemed gay:
Some stupid thing that I had done
Made my attention stray.
Repentance keeps my heart impure;
But what am I that dare
Fancy that I can
Better conduct myself or have more
Sense than a common man?
What motion of the sun or stream
Or eyelid shot the gleam
That pierced my body through?
What made me live like these that seem
Self-born, born anew?
W.B. Yeats (June 1932)
[from "The Winding Stair and other Poems" 1933]
