Song of the Dynamo

How do I know what Order brings
   Me into being?
I only know, if you do certain things,
  I must become your Hearing and your Seeing
Also your Strength, to make great wheels go round,
And save your sons from toil, while I am bound! 

What do I care how you dispose
  The Powers that move me?
I only know that I am one with those
  True Powers which rend the firmament above me,
And, harrying earth, would save me at the last—
But that your coward foresight holds me fast!
