Final answer:
Douglass employed emotional language, logical arguments with evidence, and moral appeals to persuade readers to support the abolition of slavery. His historical context and literacy played significant roles in his rhetorical strategy and content decisions in his 'Narrative'. The appendix further reinforces his arguments and targets a specific audience.
Step-by-step explanation:
Frederick Douglass used various rhetorical appeals to persuade readers in favor of abolishing slavery. By using emotional language, he was able to evoke sympathy from his readers, which is an appeal to pathos. In addition, he presented logical arguments backed with evidence, an approach known as logos. Douglass also appealed to readers' sense of morality and justice, encouraging them to see slavery as a moral failing, which aligns with the strategy of ethos. Therefore, the correct answer is d) All of the above.
Considering the historical context when Douglass was writing his Narrative, slavery had not yet been abolished in the United States, and this shaped his content decisions. To counter the institution of slavery, Douglass highlighted the sophisticated harm it caused not just to enslaved people, but also to slaveholders, demonstrating an acute awareness of his audience and the rhetorical situation. His Narrative provided evidence of the power of literacy and language, and by attaining and using his own literacy, he was able to instruct and advocate for others, rounding out the arc of his narrative with a resolution.
The appendix of Douglass's work is significant because it serves to reinforce his arguments through additional rhetorical devices and caters to a specific target audience—those still skeptical after reading the main narrative or those seeking extended commentary on slavery and morality.
