This endlessly elaborating poem
Displays the theory of poetry,
As the life of poetry. A more severe,

More harassing master would extemporize
Subtler, more urgent proof that the theory
Of poetry is the theory of life,

As it is, in the intricate evasions of as,
In things seen and unseen, created from nothingness,
The heavens, the hells, the worlds, the longed-for lands.

— Wallace Stevens, “An Ordinary Evening in New Haven”
