A poem

Today brought this poem by Czeslaw Milosz. 

Secretaries

I am no more than a secretary of the invisible thing
That is dictated to me and a few others.
Secretaries, mutually unknown, we walk the earth
Without much comprehension. Beginning a phrase in the middle
Or ending it with a comma. And how it all looks when completed
Is not up to us to inquire, we won't read it anyway.

Another of his poem has this phrase :  if not I, then someone else/ Would be walking here, trying to understand his age.
