It is according to Aristotle that a speaker or writer has three ways to persuade his audience: The first kind depends on the personal character of the speaker; the second is on putting the audience into a certain frame of mind; the third is on the proof, or apparent proof, provided by the words of the speech itself.
One of the most influential people who made a memorable speech for the past century is President John F. Kennedy, a famous public speaker who wrote an inaugural address that contains a power to persuade a lot of people.
