The Killers: Human

My cousin Kim just texted me to say that her new favorite song is "Human" from The Killers' new album. Watch and listen here.

Are we human?
Or are we dancer?
My sign is vital
My hands are cold
And I'm on my knees
Looking for the answer
Are we human?
Or are we dancer?

And from "Among School Children" by Yeats:

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?
