Man have pity on man.  
Rain from the outraged sky
drowned the innocent earth
yet the seed did not die.
Flowering from that rebirth,
man, have pity on man
as you hold the fire in your hand
that can destroy mankind
and desolate every land.
If the power and the glory is this,
a flame that burns to the bone,
what shall be left to grow
when you and your fires have gone?
What maimed and desolate few
shall recover life's full span
from among the ashes of time?
Man, have pity on man.
-Ursula Vaughan Williams
