Does the imagination dwell the most
Upon a woman won or woman lost?
If on the lost, admit you turned aside
From a great labyrinth out of pride,
… some silly over-subltle thought
Or anything called conscience once;
And that if memory recur, the sun’s
Under eclipse and the day blotted out.
— W. B. Yeats, from “The Tower,” The Collected Words of W. B. Yeats, Volume 1, The Poems (Macmillan, 1989)
