The speech President Kennedy's Report to the American People uses logos, ethos, and pathos, which are rhetorical appeals.
Explanation:
In Aristotle's rhetoric, pathos, ethos and logos are the three fundamental pillars. Nowadays, these three categories are considered different ways of convincing an audience about a particular topic, belief or conclusion.
Pathos means 'suffering and experience'. In Aristotle's rhetoric, this translates to the ability of the speaker or writer to evoke emotions and feelings in his audience. Pathos is associated with emotion, appeals to sympathizing with the audience and awakening their imagination.
In essence, pathos is to seek empathy with the audience. When used, the values, beliefs and understanding of the arbiter are involved and communicated to the audience through a story.
The pathos is used when the arguments that are going to be exposed are controversial. Since these arguments tend to lack logic, success will reside in the ability to empathize with the audience.
The second category, the ethos, means character and comes from the word ethikos, which means moral and show the moral personality. For speakers and writers, the ethos is formed by its credibility and similarity with the audience. The speaker must be trustworthy and respected as an expert on the subject.
For the arguments to be effective, it is not enough to make logical reasoning. The content must also be presented in a reliable manner to become credible.
Logos means word, speech or reason. In persuasion, the logos is the logical reasoning behind the speaker's statements. The logos refers to any attempt to appeal to the intellect, to logical arguments. In this way, logical reasoning has two forms: deductive and inductive.
