Helen Vendler teaching a W.B. Yeats poem at Harvard
"Labour is blossoming or dancing where
The body is not bruised to pleasure soul,
Nor beauty born out of its own despair,
Nor blear-eyed wisdom out of midnight oil.
O chestnut tree, great rooted blossomer,
Are you the leaf, the blossom or the bole?
O body swayed to music, O brightening glance,
How can we know the dancer from the dance?"
— W.B. Yeats, from "Among School Children"
