In his book On the Sublime, Longinus rhetorically identifies five major elements of the art of mastering the sublimity, through the use of written texts. Longinus defines sublimity as “a sort of eminence or excellence of speech […] sublimity on the other hand, produced at the right moment, overturns everything like a whirlwind and shows the power of the orator in one fell swoop” (Longinus 347). However, the risk is great when writers try to produce subliminal messages. Longinus describes the difference between falsely and truly sublime messages. He characterizes false sublimity as “puerile” and bombastic. True sublimity will touch the hearts of the audience; it goes beyond words, allowing emotions to flow. Furthermore, Longinus outlines the five rhetorical principles for achieving sublimity. (1) Ethos: greatness of thoughts, (2) Pathos: emotion, (3) Pathos: figures of speech Logos, (4) Logos: noble diction, and (5) Logos: disposition. For years, blacks fought hard to gain the same rights as whites. The late 1950s and early 1960s were a turning point for African Americans with the establishment of the civil rights era. The Civil Rights era represented a social movement for blacks in hopes of ending racial segregation and discrimination, especially in the Jim Crow Deep South. At the forefront of this movement was Dr. Martin Luther King Jr., who sought equality for the poor, victims of injustice, and African Americans by supporting peaceful protests. On August 28, 1963, King gave one of the most memorable speeches of all time during the March on Washington. Longinus' mastery of the five principles of the sublime is exemplified in King's “I Have a Dream” speech. Also, the last two minutes or…half of the paper…and, I struggle to enumerate them all” (357). Longinus argues that figures of speech reinforce the sublime, while the sublime supports it. Furthermore, many times in his speeches Martin Luther King uses figures of speech to support his passion in his speech. According to Longinus, the use of rhetorical figures is very important when advocating the sublime. King states in his speech, “With this faith, we will be able to hew from the mountain of despair a stone of hope. With this faith we will be able to transform our nation's jarring discords into a beautiful symphony of brotherhood. With this faith, we will be able to work together, pray together, fight together, go to prison together, defend freedom together, knowing that one day we will be free” (AmericanRhetoric.com). King's use of figure of speech gives a deeper meaning to his words.
