szymborska 'a note' -as in the beginning, in the newyorker:
life is the only way to tell pain from what it is not,
to go on not knowing something important.
icarus, are you falling?
Nor mouth had, no nor mind, expressed
What heart heard of, ghost guessed:
Sorrow's springs are the same.
Thought is a form of grief. Spirits Hovering Over the Ashes, p.9.
