Final answer:
Sojourner Truth utilizes logical arguments by illustrating contradictions in societal norms and her own lived experiences. She establishes credibility through personal triumphs in legal battles and her involvement in social movements. Indignation is the main emotion evoked through her passionate delivery and emphatic content.
Step-by-step explanation:
Sojourner Truth incorporates logic into her speech "Ain't I a Woman" by delineating the hypocrisy in the treatment of women and Black people. Firstly, she directly challenges the perception of women as weak by referencing her own physical strength and hard labor, which was on par with men. Secondly, she uses reductio ad absurdum by questioning the logic that suggests women need help into carriages and over ditches—privileges she, as a Black woman, never received. Finally, she addresses the religious argument that women are lesser than men because Christ was a man, by noting that Christ was born from a woman, without the aid of a man.
Truth's arguments could be considered credible for two primary reasons. Her personal experience of discrimination and hardship lends authenticity and credibility to her claims. Moreover, her status as the first Black woman to win a court case against a white man further establishes her credibility as a figure of authority and knowledge in the movements she represents.
An emotion that Sojourner Truth evokes in her speech is a strong sense of indignation. This emotion is conveyed through her passionate recounting of the injustices she has faced and her direct challenges to the arguments upholding those injustices. This sense of moral outrage is intended to move the audience to reconsider their perceptions and to rally in the fight against discrimination.
