President John F. Kennedy delivered his “We Choose to Go to the Moon” speech to a crowd of thousands at Rice University Stadium in Houston, Texas on September 12, 1962. The purpose of the speech was to address the uncertainty of the country about the time and cost of sending a man to the moon. Kennedy used rhetorical appeals and devices to achieve his purpose. He used logos by citing facts and figures about the progress of science and technology in the country. He also used pathos by appealing to emotions such as hope and fear. For example, he said “we meet in an hour of change and challenge, in a decade of hope and fear, in an age of both knowledge and ignorance.” He also used ethos by establishing his credibility as a leader who is determined and cannot be deterred. He used antithesis by contrasting knowledge with ignorance, and by contrasting space exploration with war. He also used repetition by repeating the phrase “We choose to go to the moon” several times throughout his speech. These rhetorical devices helped Kennedy connect with his audience and achieve his purpose of inspiring them to support space exploration.
