Objective Correlative and the Articulation of Vision 	

                              "the unattended
Moment, the moment in and out of time,
The distraction fit, lost in a shaft of sunlight,
The wild thyme unseen, or the winter lightning
Or the waterfall, or music heard so deeply
That it is not heard at all" 

"These are only hints and guesses,  
Hints followed by guesses;"

"The hint half guessed, the gift half understood" 
  is Objective Correlative.
