Problem: Read the following excerpt from Frederick Douglass's "Blessings of Liberty and Education" speech. Answer the question that follows. But if man is without education, although with all his latent possibilities attaching to him, he is, but a pitiable object; a giant in body, but a pigmy in intellect, and, at best, but half a man. Without education, he lives within the narrow, dark and grimy walls of ignorance. He is a poor prisoner without hope. The little light that he gets comes to him as through dark corridors and grated windows. The sights and sounds which reach him, so significant and full of meaning to the well-trained mind, are to him of dim and shadowy and uncertain importance. He sees, but does not perceive. He hears, but does not understand. The silent and majestic heavens, fretted with stars, so inspiring and uplifting, so sublime and glorious to the souls of other men, bear no message to him. They suggest to him no idea of the wonderful world in which he lives, or of the harmony of this great universe, and hence impart to him no happiness. How does Douglass's use of rhetorical appeals help him achieve his purpose?
