Here's some food for thought:
, The Collected Works of W.B. Yeats Volumn III: Autobiographies
In 1938, Mrs. Yeats told her husband, '"AE was the nearest to a saint you or I will ever meet. You are a better poet but no saint. I suppose one has to choose"' (L 838). It is a distinction Yeats seems to have already endorsed in these lines from 'The Choice', written in 1931:
The intellect of man is forced to choose
Perfection of the life, or of the work,
And if it take the second must refuse
A heavenly mansion, raging in the dark. (P 246)
But Yeats rarely makes simple choices, presenting us instead with a career of vacillations, of attempts -- always willful, sometimes heroic -- to have it both ways. No less than Keats, he thought that the poet leads a life of allegory and that his works are comments on it.
