Shadow on the Rock
At Hiroshima there’s a museum
and outside that museum there’s a rock,
and on that rock there’s a shadow.
That shadow is all that remains
of the human being who stood there on
August 6, 1945
when the nuclear age began.
In the most real sense of the word,
that is the choice before us.
We shall either end war and the nuclear arms
race in this generation,
or we will become Shadows on the rock.
— Daniel Berrigan, S. J.
