Wallace Stevens, de poesía moderna

Of modern poetry

The poem of the mind in the act of finding
What will suffice. It has not always had
To find: the scene was set; it repeated what 
Was in the script.
   Then the theatre was changed
To something else. Its past was a souvenir.

It has to be living, to learn the speech of the place.
It has to face the men of the time and to meet 
The women of the time. It has to think about war
And it has to find what will suffice. It has
To construct a new stage. (...)
