A poem begins with a lump in the throat; a homesickness or a love sickness. It is a reaching-out toward expression; an effort to find fulfillment. A complete poem is one where an emotion has found its thought and the thought has found words.
For, dear me, why abandon a belief, Merely because it ceases to be true, Cling to it long enough, and not a doubt, It will turn true again, for so it goes.
You've got to be brave and you've got to be bold. Brave enough to take your chance on your own discrimination, what's right and what's wrong, what's good and what's bad.
To Time it never seems that he is brave
To set himself against the peaks of snow
To lay them level with the running wave,
Nor is he overjoyed when they lie low,
But only grave, contemplative and grave.
Keats mourned that the rainbow, which as a boy had been for him a magic thing, had lost its glory because the physicists had found it resulted merely from the refraction of the sunlight by the raindrops. Yet knowledge of its causation could not spoil the rainbow for me. I am sure that it is not given to man to be omniscient. There will always be something left to know, something to excite the imagination of the poet and those attuned to the great world in which they live (p. 64)
