The context for this speech was the commemoration of the one hundredth anniversary of the signing of the Emancipation Proclamation, but King devotes only his first three sentences to actions of “Five score years ago”; the promise of a joyous future, made attainable by Lincoln’s signature on the proclamation, is the subject of King’s discourse. King’s purposes are to urge his followers to continue their actions and not allow the nation to return to “business as usual”; to promote changes that will eventually abolish segregation, discrimination, and prejudice across the country, especially in the South; and to convince his followers that their actions must be immediate and nonviolent.
King’s speech employs predominantly emotional strategies. His first words echo the Gettysburg Address in tribute to the “great American” whose “momentous decree” the marchers have come to celebrate, and these words set the tone, as well as readers’ expectations, for what is to come. Like Lincoln’s famous speech, King’s is crafted from connotative words like slaves, brotherhood, sacred, exalted, bright day, and warm threshold. His style borrows heavily from the great persuasive traditions of political “stump” speeches and religious sermons; his “campaign promises” are described as his “dream,” and it is King the Baptist minister who exhorts his followers to “continue to work with the faith that unearned suffering is redemptive.” Repetition of key words and phrases is characteristic of oral style, and King uses it extensively, repeating “one hundred years later,” “now,” “go back,” “I have a dream,” “let freedom ring,” and “free at last.” The most prevalent emotional strategy in the speech is King’s use of figurative language. Rich with metaphor, some passages of this speech (such as the second paragraph’s description of contemporary black status) employ metaphors in nearly every sentence. Evocative examples include “beacon light of hope,” “flames of withering injustice,” “manacles of segregation,” “chains of discrimination,” “palace of justice,” and “valley of despair.” King’s analogy comparing the U.S. Constitution and the Declaration of Independence to a “bad check” establishes America’s guilt in withholding “the riches of freedom” and automatically aligns the civil rights movement with the lofty ideal of “justice.”
King’s tone, however, avoids creating enemies or establishing dichotomies. He unites the nation in the pursuit of freedom, using the pronoun “we” and phrases such as “this is our hope . . . our freedom.” King’s speech is best remembered (and therefore probably most effective) for its “I have a dream” paragraphs (10 through 18). These psalm-like passages, whose repetitions and refrain of “I have a dream today,” incited his audience to act in 1963 and continue to inspire readers today.
In his speech, he criticizes the government’s inadequate administration of democracy and confronts the South with its archaic prejudices, citing the governor of Alabama’s obstruction of true justice and directing vitriolic criticism at Mississippi, where blacks were not allowed to vote. King’s primary purpose, however, is to inspire his audience, a goal he admirably achieves in his “I have a dream” and “let freedom ring” sequences, which conclude the discourse.
