Stevens's poetry makes one understand how valuable it can be for a poet to write a great deal. Not too much of that great deal, ever, is good poetry; but out of quantity can come practice, naturalness, accustomed mastery, adaptations and elaborations and reversals of old ways, new ways, even-so that the poet can put into the poems, at the end of a lifetime, what the end of a lifetime brings him. Stevens has learned to write at will, for pleasure; his methods of writing, his ways of imagining, have made this possible for him as it is impossible for many living poets-Eliot, for instance. Anything can be looked at, felt about, meditated upon, so Stevens can write about anything; he does not demand of his poems the greatest concentration, intensity, dramatic immediacy, the shattering and inexplicable rightness the poet calls inspiration.
