What are two of the same rhetorical devices that William Faulkner used in his Nobel prize speech with quotes?

In his Nobel Prize speech, William Faulkner employed both repetition and alliteration as key rhetorical devices. For instance, he repeatedly emphasizes the importance of the human spirit, stating, "The past is never dead. It's not even past." This repetition underscores the enduring impact of history on the present. Additionally, Faulkner uses alliteration in phrases like "the heart in conflict," which enhances the lyrical quality of his speech while emphasizing the internal struggles faced by humanity.
