I think that one may contribute (ever so slightly) to the beauty of things by making one's own life and environment beautiful, as far as one's power reaches. This includes moral beauty, one of the qualities of humanity, though it seems not to appear elsewhere in the universe. But I would have each person realize that his contribution is not important, its success not really a matter for exultation nor its failure for mourning; the beauty of things is sufficient without him.
(An office of tragic poetry is to show that there is beauty in pain and failure as much as in success and happiness.)
