-Stein, Gertrude
Of Ernest Hemingway. Quoted in R Mellow Charmed Circle (1974), ch.16.

For I have learned To look on nature, not as in the hour Of thoughtless youth; but hearing often-times The still, sad music of humanity, Nor harsh nor grating, though of ample power To chasten and subdue. And I have felt A presence that disturbs me with the joy Of elevated thoughts; a sense sublime Of something far more deeply interfused, Whose dwelling is the light of setting suns, And the round ocean and the living air, And the blue sky, and in the mind of man.
