Identify the persuasive and rhetorical techniques in this passage: "I refuse to accept the idea that the "isness" of man's present nature makes him morally incapable of reaching up for the eternal "oughtness" that forever confronts him. I refuse to accept the idea that man is mere flotsom and jetsom in the river of life, unable to influence the unfolding events which surround him. I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality." -Nobel Prize Acceptance Speech
