Robert Penn Warren (April 24, 1905–September 15, 1989)
For the basic fact about poetry is that it demands participation, from the secret physical echo in muscle and nerve that identifies us with the medium, to the imaginative enactment that stirs the deepest recesses where life-will and values reside. Beyond that, it nourishes our life-will in the process of testing our values. And this is not to be taken as implying a utilitarian aesthetic. It is, rather, one way of describing our pleasure in poetry as an adventure in the celebration of life.
