By taking that right away from Boy Willie, Bernice is also taking away the possibility of Boy Willie ever being able to live the life he's always wanted for himself, especially after years of hardship. However, just simply using logos to persuade someone isn't always enough to do the job, as other methods of persuasion, such as pathos, are used to further improve one's argument.
Using pathos, Boy Willie manipulates Berniece's emotions to try and persuade her into allowing him to sell the piano. During an argument between the two about the piano, Boy Willie brings up the fact that Berniece has yet to even tell the history of the piano to her daughter Martha. He says to her, "If you want to tell her something tell her about that piano. You ain't even told her about that piano. Like that's something to be ashamed of" (Wilson 90-91). Boy Willie uses pathos in such a way that makes Berniece feel almost guilty about not telling her own daughter the history of the piano, especially because that history is the reason as to why Berniece feels she should be sentimental about it and not sell it. By making her feel guilty, Boy Willie hopes to guilt Berneice into selling the piano. "I take my hat off whenever someone say my daddy's name. But I ain't gonna be no fool about no sentimental value" (Wilson 51). Boy Willie, once again, chose his words very carefully during this argument with Berniece. By using the basis of her argument against her, which is that the she carries too much sentiment for the piano, he's able to use a consensus-counter argument combination to make her feel bad about being sentimental. Using words such as "fool" towards it, he effectively shows her that her argument doesn't hold. But when making an argument, one must explain how he or she is credible. Using the next method of persuasion, ethos, he or she is able to easily improve the argument one step further.
