Answer:
Dr. Martin Luther King Jr. was a master at using argument techniques to achieve his purpose of securing civil rights for African Americans and promoting equality. One of his most effective methods was the use of ethos or appealing to his audience's sense of ethics and morality. He often referenced the founding principles of the United States and the principles of Christianity to demonstrate that segregation and discrimination were not just politically, but also morally wrong. He also employed pathos, or appealing to his audience's emotions, through powerful and poignant language and personal anecdotes to illustrate the human impact of segregation. Additionally, King employed logos, or appealing to reason, by presenting logical and well-reasoned arguments supported by facts and evidence. This combination of ethos, pathos, and logos allowed King to build a persuasive argument and rally support for the civil rights movement.
