Ere the birth of my life, if I wished it or no 
No question was asked me--it could not be so ! 
If the life was the question, a thing sent to try 
And to live on be YES; what can NO be ? to die. 
 
     NATURE'S ANSWER 
 
Is't returned, as 'twas sent ? Is't no worse for the wear ? 
Think first, what you ARE ! Call to mind what you WERE ! 
I gave you innocence, I gave you hope, 
Gave health, and genius, and an ample scope, 
Return you me guilt, lethargy, despair ? 
Make out the invent'ry ; inspect, compare ! 
Then die--if die you dare !
Samuel Taylor Coleridge
