“If the pages of this book contain some successful verse, the reader must excuse me the discourtesy of having usurped it first. Our nothingness differs little; it is a trivial and chance circumstance that you should be the reader of these exercises and I their author.”
– From “To the Reader” [“A quien leyere”], preface to Fervor of Buenos Aires [Fervor de Buenos Aires] (1923)

“Truly fine poetry must be read aloud. A good poem does not allow itself to be read in a low voice or silently. If we can read it silently, it is not a valid poem: a poem demands pronunciation. Poetry always remembers that it was an oral art before it was a written art. It remembers that it was first song.”
– From “The Divine Comedy” (1977)
