America is essentially a dream, a dream as yet unfulfilled. It is a dream of a land where men of all races, of all nationalities and of all creeds can live together as brothers. The substance of the dream is expressed in these sublime words, words lifted to cosmic proportions: "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty, and pursuit of happiness." This is the dream. —"The American Dream,"
Dr. Martin Luther King, Jr.

Which argument technique does King use when he refers to the Declaration of Independence with the line “We hold these truths to be self-evident, that all men are created equal”?

appeal to ethos, or ethics
repetition
appeal to logos, or logic

the speech this question is referring to is president kennedy's special message to the congress on urgent national needs, may 25, 1961

kennedy responds in a very direct and concrete way to those thinking that communism is a positive system:

"yet their aggression is more often concealed than open. they have fired no missiles; and their troops are seldom seen. they send arms, agitators, aid, technicians and propaganda to every troubled area. but where fighting is required, it is usually done by others--by guerrillas striking at night, by assassins striking alone--assassins who have taken the lives of four thousand civil officers in the last twelve months in vietnam alone--by subversives and saboteurs and insurrectionists, who in some cases control whole areas inside of independent nations." (kennedy)

president kennedy presents communism as cowardly, as a hidden and treacherous weapon that strikes from the shadows like thieves, he represents the system as not even being capable of showing and open and overt attack or confrontation. to finish up the response, he expresses that the system attacks even a country's idependence and freedom.
