Final answer:
The rhetorical appeal enhances Walker's work by establishing his credibility on racial issues, inciting emotional engagement, and presenting logical arguments, which reinforces the message and supports his purpose.
Step-by-step explanation:
The rhetorical appeal in question supports Walker's purpose by establishing credibility, appealing to the emotions of the reader, and presenting logical evidence. Walker's use of these appeals, particularly when discussing sensitive topics such as race and inequality, effectively strengthens his arguments and underscores his purpose. For instance, his ethos is established through his vocal opposition to slavery and colonization, and he manages to become a symbol of hope, demonstrating his credibility on the topic of racism in the South. Pathos is used to create a connection with the audience, possibly inciting anger at the unjust dismissal of the importance and success of African Americans, such as Dr. Martin Luther King, Jr., especially considering his work against deeply ingrained societal injustices. Lastly, the appeal to logos is evident through the presentation of facts, as when Walker sent memorials or spoke out against lynching, providing a strong logical basis for his views.
The highlights of Walker's rhetorical strategy are not only in shaping his message but also in shaping the public's view, as noted in his detailed analysis of the rhetoric used during the Civil Rights Movement and its profound impact on a national scale.
